Abstract

A recording and reproduction apparatus shifts a program which is currently being executed to a paused state, or temporarily shifts a mode of graphics drawing by an application program to an invisible mode, in order to reproduce a recorded video with trick play functionality at a reproduction speed different from a normal reproduction speed, thereby making it possible to prevent an unexpected behavior of the program even when an application program is executing a time-consuming process.

Description

RECORDING AND RECRUITING DEVICE FIELD OF THE INVENTION The present invention relates to a recording and reproduction apparatus that accumulates contents and reproduces the accumulated contents. In particular, the present invention relates to an installation for receiving a transmission wave that includes content formed of video and audio as well as data such as a program that are multiplexed in the transmission wave in synchronization with each other and transmitted, and for accumulate video, audio and data, as well as an installation to perform trick playback such as forward and rewind of content while maintaining synchronization between video and audio and data such as a program.

BACKGROUND OF THE INVENTION Various contents are included in a transmission wave sent from a transmission station. Apart from video and audio used in a normal TV program, there are cases in which data is included in the contents. There are several methods for sending the data, which can be broadly divided into a method for sending the data chronologically and a method for repeatedly sending the data by fixed interval. In the first method of sending the R? "8 3.883SS data chronologically, for example, data that continue during the course of time are sent in sequential order. This method is suitable for sending large amounts of data over a long period of time, but there is a disadvantage that the data that could not be received at the synchronization of the shipment can not be received again. On the other hand, in the second method of repeatedly sending the data at a fixed interval, the same data is sent repeatedly any number of times during a fixed period. This method has the advantage that during the period in which the same data is being sent, it is acceptable to receive any of the data pieces sent repeatedly, and in this way the reception timing is not limited. The transmission of data, represented by BML, and the sending of files through a DSM-CC data carousel are examples of this method. It is unknown, particularly in transmission, when a receiver will select a channel and reception will begin. In the method of sending the data chronologically, when the start of reception fails behind the synchronization of the sending and thus the acquisition of the data, the data can not be reacquired. Therefore, when sending data such as an application program such as video and audio in the transmission wave, the method of repeatedly sending the data by fixed interval is favorable. At present specifications have been developed and are in operation to receive a transmission wave that includes video, audio and an application program and to execute the application program and synchronization with video and audio, as in the previous method. It is possible to receive the application program sent, load the application program in a terminal and achieve several additional functions when executing the application program, instead of simply watching the video and audio. This method to send the application program and load the application program into the terminal is also called "download". For example, a specification called Digital Video Broadcasting - Multimedia Home Platform (DVB-MHP) ETSIES201812 vi .1.1 (2003-12) has been developed in Europe, and have already started operations in accordance with this specification. In addition, the specification (OCAP) OC-SP-OCAP1.0-114-050119 of the Open Cable Application Platform, which provides the same framework in the cable transmission environment, is being developed in the United States, and in Actually the operations are scheduled to start. In these specifications, the application program is written in Java language. Various Application Programming Interfaces (API), for tuning, visual presentation of graphics and the like are provided in the terminal, and the Java application program can control those functions when invoking the APIs. In addition, in North America, the OCAP-DVROC-SP-OCAP-DVR-101-040524 specification is being developed, which focuses on adding a function to record and play the contents in the OCAP specification. With this specification, the video, audio and the Java application program executed in synchronization with each other, which are sent as a cable television transmission, are recorded as a content, and, moreover, are reproduced in the same way as when the engraving content is directly reproduced from the transmission wave. The application program plays in synchronization with video and audio, in the same way as direct reproduction from the transmission wave. Furthermore, in OCAP-DVR, trick playback of the contents is achieved by recording transmission contents in a randomly accessible, high-speed storage medium, such as a hard disk, a semiconductor memory and the like. Here, trick playback refers to functions for reproducing the contents at an arbitrary speed, from an arbitrary position, and so on, such as forward, rewind, slow motion, jump and the like. With OCAP-DVR, the application program loaded in the terminal from the transmission wave can control the recording and playback of trick content. In other words, API for trick recording and playback are provided in the terminal, and the Java application program controls each function by invoking those APIs. Typically, control information for synchronization is multiplexed in advance in a transmission wave to be able to execute an application program in synchronization with video and audio. The application programs are executed and terminated one by one according to the synchronization control information. Therefore, it is possible to change to a suitable application program that will be executed for a particular video and audio scene. In addition, in accordance with the OCAP-DVR specification and the like, during playback of recorded content with trick play functionality, a terminal has to execute an application program in synchronization with video and audio playback. For example, in case a terminal advances a content, it has to execute start / end processing of an application program, graphics drawing processing by the application program and the like, at an appropriate synchronization according to the speed of content playback As mentioned above, according to the OCAP-DVR and similaree specification, during playback of recorded content with trick play functionality, a terminal has to execute an application program in synchronization with video and audio playback. However, in some cases, it is difficult for the terminal to execute an application program in synchronization with the video and audio trick playback of the recorded content. For example, in case a terminal advances recorded content, it is generally difficult to execute start / end processing of an application program, graphics drawing processing by an application program and the like, at an appropriate synchronization according to the video and audio playback speed. Typically, an application program includes these time-consuming processes that will be executed. In addition, in case an application program is executed in a terminal with slow processing speed, the start / end processing of the application program and graphics drawing processing by the application program, for example, are delayed, which triggers unexpected behavior of the application program. In order to solve the problem mentioned above, an object of the present invention is to provide a recording and reproducing apparatus for controlling unexpected behaviors of an application program, even if a terminal has to execute the application program in synchronization with the video and audio reproduction of a content recorded with trick playback functionality.

BRIEF DESCRIPTION OF THE INVENTION In order to achieve the above objective, a recording and reproducing apparatus of the present invention includes: a content reproduction unit that reproduces a content recorded in a storage medium; a program execution unit that executes a program and controls an output of the program; a content reproduction speed change unit that changes a playback speed of the content based on an inecession from the program that is in an execution condition; a trick playback detecting unit that detects one of the following: that the playback speed has been delayed from a normal playback speed to a playback speed different from the normal playback speed; and that the reproduction speed has been delayed from a playback speed different from the normal playback speed at the normal playback speed; and a trick play processing unit that instructs the program execution unit to change the state of an identified specific program of the program's program based on the detection by the trick play detection unit, and the unit program execution controls the status of the program so that the program's schedule is set to an ineffective program by the trick playback proceeding unit. For example, when the trick playback detection unit detects that the playback speed has been shifted from the normal playback speed to the different playback speed, the trick playback processing unit instructs the program execution unit change the state of the program that is in the execution execution to a state of pause, and the unit of execution of programs pauses the execution of the program in such a way that the program setting is placed in the state of pause. As mentioned above, while a terminal is playing recorded content with trick play functionality, an application program is shifted to a paused state. Therefore, it is possible to control ineeperadoe behavior of the application program. It is also possible to reduce the high load access to a semiconductor or similar memory repreented by a hard disk, a Blue-ray (BD) disk, a Digital Versatile Disk (DVD), a Secure Digital (SD) memory card and eimilaree, and reduce the deterioration of these storage media, particularly during advance and rewind. When the trick playback detection unit detects that the playback speed has been shifted from the playback speed different from the normal playback speed, the trick playback processing unit can instruct the program execution unit to change the playback speed. state of the program from the state of pause to the state of execution, and the program execution unit can resume the execution of the program in such a way that the state of the program is moved to the execution stage. The specific program can be identified based on information multiplexed in the content. The specific program can be identified based on information that has been previously registered by a privileged program of the other programs. Still, to achieve the above objective, a recording and reproducing apparatus of the present invention includes: a content reproduction unit that reproduces a content recorded in a storage medium; a program execution unit that executes a program and controls a state of the program; a graphics display unit that controls a graphics mode between a visible mode and an invisible mode, the graphics being drawn by the program executed by the program execution unit; a unit of change of speed of reproduction of content that changes a speed of reproduction of the content based on an instruction coming from the program; a trick playback detection unit that detects one of the following: that the playback speed has been delayed from a normal playback speed to a playback speed different from the normal playback speed and that the playback speed has been delayed of a playback speed different from normal playback speed at normal playback speed; and a trick playback processing unit that instructs the graphics display unit to change the graphic mode based on detection by the trick playback detection unit. For example, when the trick playback detection unit detects that the playback speed has been shifted from the normal playback speed to the different playback speed, the trick playback processing unit instructs the display unit of You can change the mode of the graphs from the stable mode to the invisible mode.

As mentioned above, while a terminal is playing recorded content with trick playback functionality, the graphic drawing by an application program is temporarily disabled. Therefore, it is possible to control unexpected behaviors of the application program. It is also possible to reduce the high load access to a semiconductor memory or the like represented by a hard disk, a Blue-Ray disk < BD), a Digital Versatile Disc (DVD), a Secure Digital (SD) memory card and similar, and reduce the deterioration of this medium storage, particularly during the advance and rewind of a content. When the trick playback detecting unit detects that the playback speed has been displaced from the playback speed different than normal playback speed, the trick playback processing unit may intrude the graphics display unit to change the playback speed. Mode of graphics from invisible mode to visible mode. The trick playback processing unit can instruct the graphic pre-exhibition unit to change a mode of only graphics drawn by a specific program identified from the other programs. The specific program can be identified based on the information multiplexed in the content.

The specific program can be identified with information that has previously been registered by a privileged program from the other program. The content and the program may be information included in a transmission wave and recorded on the storage medium. Note that the present invention can be implemented not only as the recording and reproducing apparatus mentioned above but also as a recording and reproducing method, a program for the method and a storage means for storing the program. As additional information about the technical background for this application, the decree of the application of E.U.A. Provisional No. 60/696503 filed July 6, 2005, including description, drawings and claims, is hereby incorporated by reference in its entirety.

First Mode Hereinafter, an apparatus and a method according to the first embodiment of the present invention are described with reference to the figures. The present invention focuses on the recording and reproduction of content sent and received with an arbitrary medium; however, in the present modality, a cable television telemedicine trajemieion is described as an example. In the cable television transmission system, the recording and reproducing apparatus of transmieionee (recording and reproducing apparatus) is generally called a terminal apparatus.

Figure 1 is a block diagram showing a relationship of apparatuses that constitute a transmission system; the traction module is composed of one component of the transmitter side 101 (distributor center), and terminal apparatuses: a terminal apparatus there, a terminal apparatus B112 and a terminal apparatus C113. A coupling 121 between the system of the transmission output side and each terminal apparatus is, in the cable system, a wired coupling such as a coaxial cable, an optical fiber cable and an eimilaree. In Figure 1, a system on the transmit station side is coupled to three terminated devices, but the number of devices terminated is arbitrary. The seventh side of the streaming station 101 sends information such as video / audio / data for the transmission of data in a transmission signal to a plurality of terminal devices. The tranemism signal is sent using a frequency within a frequency band established by the operational regulations of the trader, lae leyee of a region / country in which the tranemieion system is operated, and then eeyeeively. With the cable system in the present modality, the frequency band used in the tranemieion of tranemieión ee divided by each of the data details and directions of transmission (input, output) and assigned to the mémos. Figure 2 is a graph indicating an example of the division of the frequency band. The frequency band is broadly divided into doe types: Out of Band (abbreviation 00B) and In Band. 5 MHz to 130 MHz are assigned as 00B, and are used mainly in the exchange of input / output data between the component of the transmission side 110 and the terminal apparatus there, the terminal apparatus B112 and the terminal apparatus C113. 130 MHz to 864 MHz are assigned as In-Band, and they operate mainly on a single-output channel that includes video / audio. The QPSK modulation format is used with OOB, and the QAM64 or QAM256 modulation format is used with In Band. The modulation formatting technology is generally known and is of little concern for the present invention, and therefore detailed descriptions are omitted. Figure 3 is an example of a more detailed design of the frequency band OOB. They are 70 MHz to 74 MHz in the sending of output data from the system on the transmission station side 101, and all of the terminal apparatus. There, the terminal apparatus B112 and the terminal apparatus C113 receive the same data from the same seventh side. On the other hand, they are 10.0 MHz to 10.1 MHz in the sending of input data of the terminal device there to the system of the transmission output side 101; They are 10.1 MHz to 10.2 MHz when the input data of the terminal apparatus B112 is sent to the system on the transmission station side 101 and 10.2 MHz to 10.3 MHz are used in the sending of input data of the terminal device C113 to the seventh side It is possible to independently send unique data from each terminal apparatus there, B112 and C113 to the system of the tranemission station side 101. Figure 4 is an example of use of a frequency band In FIG. Band. 150 MHz to 156 MHz and 156 MHz to 162 MHz are allocated to a TV channel 1 and to a TV 2 channel repectively, and later, TV channels are assigned at 6 MHz intervals. The radio channels are assigned in 1 MHz units of 310 MHz and above. Each one of these channels can be used as analogous tranemission or digital transmission. The digital transmission is sent in TS packet format with baee in the MPEG-2 specifications and it is also possible to send varioe data types such as data transmission data and TV program organization information to configure EPG, in addition to audio and video. The system of the transmission station side 101 is connected to the frequency range described above to send a suitable signal to the terminal devices, and therefore has a modulation unit QPSK, a modulation unit QAM, and so on. In addition, the system on the transmission station side 1O1 has a QPSK demodulator to receive data from the terminal devices. Still further, the system on the transmitting station side 101 can be conceived as having various dielectricities related to the modulation unit and the demodulation unit. However, the present invention relates mainly to terminal devices, and therefore the detailed descriptions are omitted. Meanwhile, the terminal devices There, B112 and C113 each have a QAM demodulation unit and a QPSK demodulation unit for receiving and reproducing a transmission signal from the transmission station side system 101. In addition, each terminal apparatus has a QPSK modulation unit to be able to send unique data to the seventh on the tranemission output side 101. In the present invention, the end devices are recording and reproducing apparatuses of transmisionee (recording and reproduction apparatuses), and the detailed configurations are describe later. The system on the transmission station side 101 modulates an MPEG-2 driver stream and transmits the current within the transmission signal. A terminal apparatus receives the signal of tranemission, demodulates and reproduces the MPEG-2 transport stream and extracts necessary information from the current, and uses it. In order to describe a device function and connection structure present in the terminal apparatus, a structure of the MPEG-2 transport stream is first written in a simple manner. Figure 5 is a diagram that shows the structure of a TS packet. A TS 500 packet has a length of 188 bytes, and is composed of a header 501, an adaptation field 502 and a payload 503. The header 501 contains control information of the TS packet. The header has a length of 4 bytes, and has the structure mapped to 504. In the header 501, there is a field indicated as "Package ID" (hereinafter PID), and the TS packet is identified through the value of its PID The adaptation field 502 contains additional information such as time information. The adaptation field 502 does not necessarily have to be present, and there is a reason why the adaptation field 502 is not present. The payload 503 contains information carried in the TS packet, such as video, audio and data tranemission data. Figure 6 is a schematic diagram of a MPEG-2 tranent stream. The TS package contains varied information on the payload, such as video, audio, data used for data transmission and eimilaree. A TS 601 packet and a TS 603 packet each contain a PID 100 in the header, and contain information that refers to video 1 in the payload. A TS 602 packet and a TS 605 packet each contain a PID 200 in the header, and contain information referring to data 1 in the payload. A TS 604 packet contains a PID 300 in the header, and contains information that refers to audio 1 in the payload. Mixing TS packets containing various types of data in the uploads and sending these packets as a series in sequence is called multiplexing. A transport stream MPEG-2 600 is an example of a configuration in which the TS packets 601 to 605 are multiplexed. TS packages that have identical PIDs contain identical types of information. Thus, the terminal apparatus reproduces video and audio, and reproduces data such as TV program organization information, when receiving multiplexed TS packets and extracting, according to the PID, the information contained in the TS package. In Figure 6, the TS 601 package and the TS 603 package each carry information referring to video 1, and the TS 602 package and TS package 605 each carry information that refers to the data 1. Here, a description is given that refers to a format of each type of data contained in the payload. Video and audio are referenced by the format called a Packaged Element Current (PES) packet. The PES package includes video information or audio information of certain hours of a day, and upon receipt of the PES packet, the recording and reproduction apparatus of transmissions can send the video and audio information contained in that PES packet to a screen and a speaker The transmission station transmits the PES packets without pause, and therefore it is possible for the transmission recording and reproducing apparatus to continuously reproduce the video and audio without pause. When the PES packet is actually transmitted, the PES packet is divided and stored in the load of a plurality of TS packets in case the PES packet is larger than the payload of a TS packet. Figure 7 shows an example of inhibition when carrying a PES packet. A PES 7-01 package is too large to be stored and transmitted on a payload of a single TS packet, and therefore the PES 701 package is divided into a PES A 702a package division, a PES B 702b package divice. and a PES C 702c packet partition, and it is carried in three TS 703 packets to 7051 which have id PIDs. Actually, video and audio are each obtained as an elementary stream (ES) obtained by concatenating data contained in the payloads of a plurality of PES packets. The format of this elementary stream is digitized video and audio, as defined by the MPEG-2 video standard, the MPEG-1 and 2 audio standard, and eimilaree. On the other hand, information such as TV program organization information and data for the transmission of data are expressed using a format called MPEG-2 section. When the MPEG-2 section is actually transmitted, the MPEG-2 section is divided and stored in the payloads of a plurality of TS packets in case the MPEG-2 section has a size larger than the payload of a packet. TS. Figure 8 shows an example of division when taken to the MPEG-2 section. As an MPEG-2 801 eection large enough to be stored and transmitted in a payload of a single TS packet, the MPEG-2 801 eection is divided into a Section A 802a partition, a Section B 802b division and a division. of section C 802c, and ee carried in three TS 802 to 805 packets that have identical PIDs. Figure 9 expresses a structure of the MPEG-2 section. An MPEG-2 900 section is configured with a header 901 and a payload 902. The header 901 contains control information of the MPEG-2 section. That configuration is expressed by a header configuration 903. The payload 902 contains data carried in the MPEG-2 900 section. A table identifier (hereafter, table_id) present in the header configuration 903 expresses the type of the MPEG section -2, and a table identifier extension (hereinafter, table_id_exteneion) is an extension identifier used when distinguishing more between MPEG-2 sections with an identical table_id. In case the TV program organization information is transmitted, as in Figure 10, it can be given as an example of using the MPEG-2 section. In this example, as indicated in row 1004, information necessary to modulate the broadcast signal is indicated in the MPEG-2 section having a table_id of 64 in the header structure 903, and this MPEG-2 section is furthermore in a TS packet assigned with a PID of 16. The PES format does not exist in the case of the MPEG-2 section. For this reason, the elementary stream (ES) is a concatenation of the payloads of TS packets identified by identical PIDs within the transport stream MPEG-2. For example, in Figure 8, the package TS 803 to 805, in which the section is divided and taken MPEG-2 801, all are defined with the PIDs of 200. It can be said that these are the ESs that carry the MPEG-2 801. A concept called a program exists in addition to the MPEG-2 tranent stream. The program is expressed as a collection of ESs, and is used in case the management of a plurality of ESs is combined. When the program is run, it is possible to manage video / audio, as well as data of accompanying data transmission, all together. For example, in the case of simultaneously managing the video / audio that will be reproduced, by grouping the ES and video and the audio ES as a program, the recording and reproduction apparatus of transmissions must simultaneously reproduce these ESs as a program of TV. To expire the program, two tables, called a Program Map Table (PMT) and a Program Association Table (PAT) are broadcast in MPEG-2. Detailed descriptions can be found in the specifications of ISO / IEC 13818-1, "MPEG-2 Syetems". The PMT and the PAT are described below in simple terms. The PMT is a table, like many of which are included in the MPEG-2 transport stream as the program number. The PMT is configured as an MPEG-2 section, and has a table_id of 2. The PMT contains a program number used to identify the program and additional program information, as well as information that refers to the ESs that belong to the program. An example of the PMT is given in Figure 11. 1100 Displays a program number. Program numbers are uniquely assigned to program in the current transport element, and are used to identify PMTs. The rows 1111 to 1114 express information referring to individual ESEs. A column 1101 shows types of ESs, in which "video", "audio", "datoe" and so on are specified. A column 1102 shows the PIDs of the TS packet that constitute each ES. A column 1103 shows additional information that refers to ESs. For example, the ES shown in row 1111 is an audio ES, and is carried in a TS packet with a PID of 5011. The PAT is a table, of which only one is present, in the MPEG transport stream. 2. The PAT is configured as an MPEG-2 section, has a table_id of 0, and is carried in a TS packet with a PID of 0. The PAT contains a transport stream identifier (hereinafter, transport_etream_id) for the identification of the MPEG-2 driver stream, and information that refers to all PMTES that represent exogenous programs in the MPEG-2 transport stream. An example of the PAT is given in figure 12. 1200 It is a transport_stream_id. The transport_etream_id is used to identify the MPEG-2 driver stream. Lae hilerae 1211 to 1213 express information that refers to the programs. A column 1201 shows the program number. A column 1202 shows the PIDs of the TS packet carrying the PMTe that correspond to respective programs. For example, the PMT of the program shown in row 1211 has a program number of 101, and the corresponding PMT is carried in the TS packet with a PID of 501. In case the terminal apparatus reproduces a certain program, the terminal apparatus It uses the PAT and the PMT and identifies the video and audio that constitute the program, and reproduces that video and audio. For example, with respect to the transport stream MPEG-2 carried by the PAT in Figure 12 and the PMT in Figure 11, the following procedure is followed in that the video and audio belonging to the program with a number of 101 program are played. First, a PAT transmitted with an MPEG-2 section with a table_id of "0" is acquired from a TS packet with a PID of "0". The PAT is scrutinized to find a program with program number "101", and row 1211 has been obtained. From row 1211, the PID "501", of the TS package that carries the PMT of the program with a program number "101" obtained. Deepuée, the PMT taken as the MPEG-2 section with a table_id of "2" acquired from the TS package with the "SOI" PID. A row 1111, which is audio information IS, and a row 1112, which is video information ES, are obtained from the PMT. A PID "5011" of the TS packet carrying the audio ES is obtained from the row 1111. In addition, a PID "5012" of the TS packet carrying the audio ES is obtained from the row 1112. Afterwards, a packet is acquired Audio PES and the TS packet with a PID "5011", and a PES video package of the TS packet with a PID of "5012" is acquired. Through this, it is possible to obtain the PES packages of video and audio that will be reproduced, and the video and audio carried in these packages can be reproduced. Note that there are cases in which the MPEG-2 transport stream is randomized. This is a scenario called conditional access system. For example, by randomizing PES packets that carry certain video and audio, only those who can descramble them are able to see video and audio. In order to be able to randomize and watch the video and audio, an observer must randomize them using a device called a descrambler. For example, in a terminal apparatus compatible with OCAP, an adapter in the form of a card with an internal descrambler is used. A cable television operator distributes a device programmed to be able to descramble a program specified to each listener, and the listener ineerta eee adapter in the terminal apparatus. Once this is done, the adapter will randomize the program specified with baee into the randomization information, such as a key to the randomization and contract information of each contract holder. A method for descrambling, a method for obtaining a descrambling key and eimilar are dependent on the adapter, and have no influence on the implementation of the present invention. So far, simple descriptions have been given regarding the MPEG-2 specification, and detailed definitions of terminology are given hereinafter. In the present invention, doe typee of the term "program" exempt. One is "a program" that appears in the MPEG-2 specifications, and the other is a "program" that refers to an assembly of codes executed by a CPU. Since the former is synonymous with the term "service" used in the operating regulations, hereafter, to avoid confusion, the former is called "service" and the latter is simply called "program." Still, in relation to the latter, a "program" written particularly in the Java ™ language is called a "Java program". A decree has been given with respect to various types of general information specified in the MPEG-2 specifications in accordance with the present invention. In the following, the reproduction and recording terminal of tranemieionee in the present modality is described in detail. Figure 13 is a block diagram showing a general hardware configuration of the transmit recording and reproducing apparatus according to the present embodiment; in another word, a specific internal configuration of the terminal apparatuses 111, 112 and 113 shown in figure 1. 1300 is a recording and reproduction apparatus of tranemieionee, which is configured of: a tuner 1301; a TS decoder (TS demultiplexer) 1302; an AV 1303 decoder; a loudspeaker 1304; a visual presenter 1305; a CPU 1306; a secondary storage unit 1307; a primary storage unit 1308; a ROM 1309; an input unit 1310; an adapter 1311; an AV 1312 encoder; a multiplexer (Multiplexer of Traneporte Streams MPEG-2 or similar) 1313 and a plane of graphs 1314. Note that the present modality obtains when expanding a terminal of recording and reproduction of tranemieiones achieved by the specifications OCAP-DVR, and the configuration of hardware basic ee caei identical to that required by the OCAP-DVR specifications. The tuner 1301 is a diepoeitive which modulates a transmission signal modulated and transmitted from the transmission side of the transmission side 101, according to tuning information such as a frequency and similar specified by the CPU 1306. Here, e-tuning information ee information in which a frequency, a modulation format and similar can be specified. An MPEG-2 trastream obtained as a result of the demodulation can be a tuner 1301 is sent to the TS decoder 1302 via the adapter 1311 with a descrambling function. The decoder of TS 1302 is a device that has the function of segregating PES packets and section MPEG-2 that meet specified conditions from the MPEG-2 tranent stream, based on a PID, a section filter condition and so forth, prescribed by the CPU 1306. In the event that a transmission is received and a service is played without recording, the transport stream MPEG-2 sent by the adapter 1311 is input to the decoder of TS 1302. On the other hand, in In case of reproducing a service recorded in the secondary storage unit 1307, the MPEG-2 driver stream that sends the secondary storage unit 1307 is input to the TS 1302 decoder. Which input to receive is controlled by the CPU 1306. The PES packets of the video and audio that the TS decoder segregated are sent to the AV decoder 1303. In addition, the MPEG-2 section segregated by the TS 1302 decoder is transferred to the unit. Primary storage 1308 through Acceeo to Direct Memory (DMA), and is controlled by a program executed by the CPU 1306. The decoder of AV 1306 is a device with a function of decoding the ES of video and encoded audio ES. The AV decoder extracts the ES from the PES packet that carries the audio and video information transferred from the TS decoder, and decodes the ES. An audio signal and a video signal obtained through the decoding carried out by the AV decoder 1303 are sent to the loudspeaker 1304 and the visual presenter 1305 at the time of service playback, but are sent to the AV encoder 1302 at the time of service recording. Which output route to take is controlled by the CPU 1306, according to an instruction from a user. The loudspeaker 1304 reproduces audio sent from the AV decoder 1303. The visual presenter 1305 plays video sent from the AV decoder 1303, and presents graphically on the drawing plane 1314 drawn by the CPU. The CPU 1306 executes a program that operates in the recording and reproduction apparatus of tranemieionee. The CPU executes a program contained in the ROM 1309. Or, the CPU 1306 executes an overloaded program of a transmission signal or a network and content in the primary storage unit 1308. Or, the CPU executes a program downloaded from a signal of transmission or a network and content in the secondary storage unit 1307. The tuner 1301, decoder of TS 1302, the decoder of AV 1303, speaker 1304, visual presenter 1305, secondary storage unit 1307, primary storage unit 1308, ROM 1309 , input unit 1310, adapter 1311, AV encoder 1312, multiplexer 1313 and graph plane 1314 eon controlled in accordance with the inetruction of the executed program. In addition, the CPU 1306 is able to control the adapter 1311 through communication not only with the device within the terminal apparatus 1300, but with the dielectric components within the adapter 1311. The secondary storage unit 1307 is a memory device, whose memory It is not erased even if the power supply to the device is interrupted. The secondary storage unit 1307 is configured from a device in which the information is not erased even if the power to the terminal apparatus 1300 is soiled; for example, a non-volatile memory such as a FLASH-ROM, a Hard Dieco Unit (HDD), a rewritable medium such as a CD-R and a DVD-R. The secondary storage unit 1307 stores information based on an instruction from the CPU 1306. The primary storage unit 1308 is a device that has a function of temporarily storing information according to an instruction coming from the CPU 1306, a capable device. of traffic by DMA, and e ectively, and it is configured of a RAM or eimilaree. ROM 1309 is a non-rewritable memory device, and for specific purposes, it is configured with a ROM, a CD-ROM, a DVD, and similar ones. The program executing the CPU 1306 is stored in the ROM 1309. The input unit 1310 is, to be more specific, configured from a front panel or a remote control receiver, and accepts input from the user. Figure 14 is an example of the case in which the input unit 1310 is configured from the front panel. A front panel 1400 has seven buttons. A cursor up button 1401, a cursor down button 1402, a left cursor button 1403, a right cursor button 1404, an OK button 1405, a cancel button 1406, an EPG button 1407 and a mode change button 1408 When the user presses a button, an identifier of the button pressed is notified to the CPU 1306. The adapter 1311 is a device for descrambling a randomized MPEG-2 trant stream carried in the In-Band frequency scale, and includes one or more desaleatorizadoree. The MPEG-2 driver stream sent by the tuner 1301a is input to the adapter 1311, and the descrambling is carried out in the TS packet having the PID specified by the CPU 1306. The 1311 adapter sends the MPEG- 2 is randomized to the TS 1302 decoder. Furthermore, the 1311 adapter also carries format formatting of the data sent on an OOB frequency scale. The information that was sent in OOB is modulated in the QPSK modulation format. With respect to the output tranemission, the QPSK demodulator 1301B demodulates the output signal sent from the system on the transmission station side 101, and inputs a bitstream generated in the adapter 1311. The adapter 1311 extracts information specified by the CPU 1306 among different information included by the stream of bite, converts the information into a format that can be interpreted by a program that operates on the CPU 1306, and provides this to the CPU 1306. On the other hand, with respect to the transmission of In this case, the CPU 1306 enters information that will be sent to the system on the transmission side 101, on the adapter 1311. The adapter 1311 converts the information gathered from the CPU 1306 into a format that can be interpreted by the station-side system. Transmission 101, and enter the QPSK 1301c modulator. The QPSK modulator 1301c, modulates by QPSK the information provided from the adapter 1311, and sends this to the system on the transmission station side 101. A CableCARD, formerly called a Point of Installation (POD), used in the cable system of the United States, can be given as a specific example of the 1311 adapter. The AV 1312 encoder encodes the audio signal decoded by the AV 1303 decoder into audio in the format of MPEG audio, and encodes the video signal in video in the MPEG video format. The AV encoder 1312 sends the encoded video and audio to the multiplexer 1313. The multiplexer 1313 is a device with a video and audio multiplexing function input from the AV encoder 1312, into the transport stream MPEG-2. The graphics plane 1314 is a device - which has a function of temporarily storing graphics drawn by the CPU. The graphics drawn on the graphics plane 1314 are fused with video sent from the AV decoder 1303 and pre-installed on the old pre-eater 1305, according to an instruction from the CPU to transfer the graphics to the visual presenter 1305. An operation in which the transmission recording and reproducing apparatus described above records a service contained in a tranemission wave in the secondary storage unit 1307, and an operation in which the transmitter recording and reproducing apparatus simultaneously reads the service of the unit. secondary storage 1307 and reproduces it, are hereinafter described in detail. First, an operation is described in which service contained in the wave of transmissions is recorded in the secondary storage unit 1307. Figure 15 shows a conceptual diagram representing the sequence in physical connections, processing details and input data format / output of each device during the recording of the service. 1500 is a terminal apparatus, which has: to the tuner 1301; to adapter 1311; an evaluator 1501; the decoder of TS 1302; a PID filter 1502; a section filter 1503; the AV 1303 decoder; the primary storage unit 1308; the AV 1312 encoder; the multiplexer 1313 and a recording area 1504. The constituent elements in FIG. 15 having the reference numerals which in FIG. 13 have the same functions and thus are omitted in this way. First, the tuner 1301 performs tuning in the tranemission wave according to tuning information specified by the CPU 1306. Here, the information tuning information in which a frequency, a modulation format and the like can be specified. The tuner 1301 deemodulates the transmission wave and enters the transport stream MPEG-2 on the adapter 1311. The descrambler 1501, which is included in the adapter 1311, descrambles the MPEG-2 tranent current with baee in conditional access information for each obeyer. The descrambled MPEG-2 transport stream is fed into the TS decoder. Doe types of devices that process the MPEG-2 transport stream are present within the TS 1302 decoder. The PID filter 1502 and the output filter 1503. The PID filter 1502 extracts, from the input stream MPEG-2 inputted , a TS packet having a PID specified by the CPU 1306, and then extracting a PES packet and an MPEG-2 section presente in that payload. For example, when the transport stream MPEG-2 in Figure 6 is entered in the event that the CPU 1306 has instructed PID filtering to extract the TS packet with a PID = 100, packets 601 and 603 are extracted, then This is done by reconnecting a PES packet from a video 1. Or, when the MPEG-2 driver stream in Figure 6 is incremented in the event that the CPU 1306 has intruded PID filtering that extracts the TS packet with a PID = 200, the packet is 602 and 605 eon extracted, then concatenated and in this way an MPEG-2 section of datoe 1 is reconfigured. The output filter 1503 extracts the MPEG-2 action that conforms to a section filter condition specified by the 1306 CPU among the entered MPEG-2 sectionsand, by DMA, this MPEG-2 section is transferred to the primary storage unit 1308. For example, it is assumed that CPU 1306 will specify, for the section filter 13503, PID filtering that extracts the TS packet with a PID = 200, and section filtering that extracts a section with a table_id of 64. As mentioned above, after the MPEG-2 section of the data 1 is reconfigured, the section filter 1502 extracts only the section with a table_id of 64 between those MPEG-2 sections, and transfer by DMA this to the primary storage unit 1308. The MPEG-2 section that is input to the primary storage unit 1308 is entered into the multiplexer 1313.

A video PES packet and a PES audio packet extracted by the TS 1302 decoder are encoded in the AV decoder 1303. The AV decoder decodes the PES video packet in order to convert it into video, and enters this in the AV encoder 1312. The AV decoder also decodes the PES audio packet to convert it into audio, and enter this into the AV 1312 encoder. The AV 1312 encoder converts the video into MPEG video and enters this into the multiplexer 1313. The AV 1312 encoder also converts the audio into MPEG audio and enters this into the multiplexer 1313. The multiplexer 1313 multiplexes the MPEG video and the MPEG audio input from the AV encoder into the MPEG-2 section input from the unit. primary storage 1308, and thus generate a MPEG-2 tranent stream. The generated MPEG-2 transport stream is recorded in the recording area 1504. The recording area 1504 is comprised of all or part of a secondary storage unit 1307, or other recording area, and stores in the MPEG transport stream. -2 that constitutes a service. Next, an operation is described in which the service is read consecutively from the secondary storage unit 1307 and reproduced. Figure 16 shows a conceptual diagram that depicts the frequency of physical connections, processing details, and input / output formats of each die during the recording of the service. 1600 It is a terminal apparatus which has: the recording area 1504; the decoder of TS 1302; the PID filter 1502; the section filter 1503; the AV 1303 decoder; the loudspeaker 1304; the pre-eater 1305 and the primary storage unit 1308. The constituent element in FIG. 16 having the same reference numerals as in FIG. 13 has the same function and in this way omits the description. The MPEG-2 driver stream recorded in the recording area 1504 in the procedure described in FIG. 15 is input to the TS 1302 decoder. Next, a video ESP and an audio PES having the PIDs specified by the CPU. 1306 are extracted by the PID filter 1502 within the decoder of TS 1302. The extracted PES packets are entered in the decoder of AV 1303. Or, the MPEG-2 section having the PID and table_id specified by the CPU 1306 is extracted by the PID filter 1502 and the separation filter 1503 within the decoder of TS 1302. The extracted MPEG-2 output is transferred by DMA to the primary storage unit 1308. The video PES and the audio PES are incremented in the decoder of AV 1303 are decoded and sent with an audio signal and a video signal. Deepuée de eeo, the audio signal and the video signal are recorded in the visual previewer 1305 and the loudspeaker 1304, reproducing audio and video in this way. The MPEG-2 section entered in the primary storage unit 1308 is input to CPU 1306 as appropriate. At this time, an example of a hardware configuration relating to the present invention has been defined. Hereinafter, a main function of the present invention is described, which is the control of the recording and the control of the trick reproduction of an eervice by means of a Java program. The recording of the service in the present invention refers to recording video, audio, a Java program, synchronization information of the Java program and so e ectively that are contained in the service, in a recording medium such as a hard disk, a Blue disk -ray (BD), a Digital Versatile Disk (DVD) and a Secure Digital Memory (SD) card. The reproduction of the service refers to the reproduction and execution of the video, audio and Java program recorded in the recording medium, based on the synchronization information. A reproduction result of a recorded service requires that it be almost equivalent to a result of directly reproducing the service after receiving a tranemission wave. Figure 17 is a configuration diagram of a program needed to record and reproduce the service, and the software recorded in ROM 1309. A 1700 program is made up of an OS 1701, an EPG 1702, a Java VM 1703 and a Java library 1704, which is eubprogramae. OS 1701 is an Operating System; Linux, Windows, and similar are examples. OS 1701 is comprised of: a core 1701a to execute other e-programs such as EPG 1702 and VM Java 1703 and a library 1701b operated by the e-program to control the constituent element of the terminal apparatus 1300. The core 1701a of the publicly known technology and therefore, a detailed description is omitted. The library 1701b provides, for example, a tuning function to control the tuner. The library 1701b receives, from another subprogram, tuning information in which a sequence, modulation format and the like can be specified, and supplies this to the tuner 1301. The tuner 1301 performs deemodulation with baee in the tuning information provided, and can pass the MPEG-2 transport stream deemodulated to the TS 1302 decoder.

As a result, other e-programs can control the tuner 1301 through the library 1701b. Also, library 1701b provides channel information to uniquely identify a channel. An example of channel information is shown in Figure 20. Channel information is sent using an OOB or a frequency scale In Band, it is converted into a graph format by adapter 1311, and is stored in a temporary memory unit which can be accessed by the library. A 2001 column identifies channel identifiers, and is equivalent to, for example, source identifiers (hereafter, source_IDe) as defined by SCTE65 Service Information Delivered Out-Of-Band For Digital Cable Televisions. A column 2002 mueetra name of channel, and ee equivalent to name of origin (hereinafter, eource_name) and eimilaree, of the member norm SCTE65. A column 2003 of the tuning information, and information in which a frequency, a traneference rate, a modulation format and the like can be specified, which is given to the tuner 1301. A 2004 column shows program names to identify the PMEs . For example, a 2011 row is a group of service information that includes a channel identifier of "1", a channel name of "channel 1", a frequency of "150 MHz ..." in the tuning information and a program number of "101".

The Java VM 1703 is a Java virtual machine that sequentially analyzes and executes programs described in the Java ™ language. The programs written in the Java language are compiled from intermediate code that do not depend on hardware, called byte code. The Java virtual machine is an interpreter that executes this byte code. The Java VM 1703 runs the Java 1704 library that is written in the Java language. Details of Java language and Java VM are explained in publications such as "Java Language Specification" (ISBN 0-201-63451-1) and "Java Virtual Machine Specification" (ISBN 0-201-63451-X), and ae eectively. In addition, it is possible to invoke or be invoked by other e-programs not written in the Java language through a native Java interface (JNI). Details that refer to the NYI can be found in the book "Native Java Interface" and then eagerly. The Java library 1704 is a library written in the Java language and which is invoked by the Java program to be able to control functions of the tranemieionee recording and playback apparatus. However, there are situations in which a program written in non-Java language, such as library 1701b of OS 1701, is used as needed. The Java program can use a function provided by the Java library 1704 when invoking a Java Application Programming Interface (API) contained by the Java library 1704. A Tuner 1704c is a Java library to control the reception tuner In Band 1301a in the Transmieionee recording and playback terminal. When the Java program parses tuning information to the tuner 1704c, the tuner 1704c has information to invoke a function of tuning the library 1701b, and as a result, it is possible to control an operation of the reception tuner in band 1301a of the recording terminal and reproduction of transmisionee. Here, tuning information is information in which a frequency, modulation format and format can be specified. An SF 1704e is a Java library for controlling a function of the PID filter 1502 and the output filter 1503 of the recording and playback terminal of tranemieionee. When the Java program paes filter conditions as a PID, table_id, and SF 1704e, the SF 1704e uses a function of the library 1701b and similarly with baee under those conditions, in order to control the PID filter 1502 and the section filter 1503, acquires an MPEG-2 section that satisfies filter conditions and passes the MPEG-2 section to the Java program that established the filter conditions. A DSM-CC 1704d is a Java library to access a file system of a DSM-CC object carriage. The DSM-CC object carousel is included in the MPEG-2 section acquired by the SF 1704e. The DSM-CC is defined by ISO / IEC 13818-6, and it is a mechanism to use the MPEG-2 section for the way to carry an arbitrary file. By using this, it is possible to send a file from a transmission station to a terminal. Based on a file identifier and defined by the Java program and successively, the DSM-CC 1704d uses the SF 1704e and acquires the MPEG-2 section, extracts a file based on ISO / IEC 13818-6 and sends this file to the primary storage unit 1308. A detailed method for implementing the DSM-CC has no relation to the present invention and therefore details are omitted. An AM 1704b is an application program manager that provides a function to manage the execution and termination of the Java program contained in the service. The AM 1704b extracts a Java program multiplexed on a specified channel from a specified MPEG-2 transport stream, and causes the execution or termination of that extracted Java program according to synchronization information multiplexed separately. A Java class file of the Java program is multiplexed into the transport stream MPEG-2 in the DSM-CC format mentioned above. In addition, the synchronization information of the Java program is multiplexed in the MPEG-2 driver stream in a format called AIT. AIT is an acronym for Application Information Table, as defined in Section 10 of the DVB-MHP specification (ETSITS 101812 specification DVB-MHP VI.0.2, and is an MPEG-2 section with a table_id of "0x74". A detailed configuration of the AM 1704b is shown in Figure 27. The AM 1704b is configured of an AIT 2711 monitoring unit and a 2712 application release management unit. The AIT 2711 monitoring unit monitors the updating performance of the AIT that receives an MPEG-2 trainer stream and a channel identifier as input, and the AIT is up-to-date, notifies the admin unit of application step 2712 and the trick play interval proceeding unit 2703 of the updated AIT First, the JMF 1704b searches for channel information in the library 1701b using a channel identifier specified as a key, and finds the program number. When the SF 1704e is removed and eimilaree, it acquires a PAT of the MPEG-2 transport stream. Then, the PID of a PMT that corresponds to the program number obtained is obtained from information of the PMT. Again, using the SF 1704e, the actual PMT is acquired. The acquired PMT is in a format like the one shown in figure 11, and it has written the PID of an elementary stream that has "datoe" as a type of current and "AIT" as complementary information. Still, when the PID and table_id "0x74" of the AIT now obtained as the filter conditions are given to the SF 1701e, the real AIT is obtained. Fig. 22 is a graph schematically showing an example of AIT information. A version number of AIT 2200 expresses the version of that AIT. The higher the AIT version, the newer the AIT will be. An AIT of the same period of AIT is received repeatedly, but the AM 1704b does not analyze an AIT with the same version of AIT as an AIT that has already been analyzed, but analyzes only one AIT that is newer than the AIT already analyzed. and carries out the corresponding processing. A 2201 column identifies identifiers for Java programs. A column 2202 displays the control information of the Java program. As the control information, exempt "self-start", "present", "delete" and similaree; "autostart" means that the terminal apparatus 1300 executes the Java program automatically in an instant, "present" means that it does not perform automatic execution and "delete" means stopping the Java program. A column 2203 is a DSM-CC identifier to extract the PID that includes the Java program in the DSM-CC format. A column 2204 is a program name of the Java program. A column 2205 is a paused indicator corresponding to each Java program. The paused indicator is an indicator that indicates whether the corresponding Java program is going to be or not paced during trick playback. The "true" value of the paced flag means that the corresponding Java program is paused in a trick play mode, and then, when the trick play mode is canceled to return to a normal play mode, the execution of the Java program paused is restarted. The "low" value of the paced flag means that the corresponding Java program continues to be executed without being paged even in a trick play mode. In Figure 22, as a Java program "/ a / TopXlet" that corresponds to a Java program identifier "301" has its paused indicator value of "true", the Java program is paced during trick playback. Lae hilerae 2211, 2212, 2213 and 2214 are a group of information on Java programs. The Java program defined in row 2211 is a group that includes a Java program identifier "301", "autostart" control information, a DSM-CC identifier "1", a program name "a / TopXlet" and a pacionada indicator "true". Likewise, the program defined in row 2212 is a group that includes a Java program identifier "302", "present" control information, a DSM-CC identifier "1", a program number "b / GameXlet "and a" false "flag. Here, the three Java programs defined in lae hilerae 2211, 2212 and 2214 have the same DSM-CC identifiers. This indicates that the tree that Java is programmed into will be included in a file system encoded in the DSM-CC format. Here, five types of information are prescribed for each Java program, but in reality, more types of information are included. Details can be found in the DVB-MHP specification. The application release management unit 2712 manages the execution status of the Java program by accepting a request from the trick play interval processing unit 2702 or by analyzing the updated AIT details paired from the AIT monitoring unit 2711. First, the operation of the application state management unit 2712 is described hereinafter when the AIT is passed from the AIT 2711 monitoring unit. The application e-mail management unit 2712 finds a Java program with "autostart" within the AIT, and extracts the corresponding DSM-CC identifier and a Java program name. Referring to Fig. 22, the application release management unit 2712 extracts the Java program from row 2211 and acquires the DSM-CC identifier of "1" and the Java program name of "a / TopXlet". Next, the application management unit of application 2712 uses the acquired DSM-CC identifier of the AIT for this way to acquire, from the PMT, the PID of the TS package that stores the Java program in the DSM-CC format. Specifically, the PID of the elementary stream with a conformation DSM-CC identifier in the complementary information and which has a current type of "datoe" is acquired from the PMT. Assuming here that the DSM-CC identifier is "1" and the PMT is like that of Figure 11, the elementary stream current 1114 conforms to the previous elementary stream, and the PID "5014" is extracted. The application management unit of application 2712 specifies, to SF 1704e, the selection filter conditions and the PID of the TS packet carrying the MPEG-2 section inserted with data in the DSM-CC format. Here, the PID "5014" is given. As a result, the application state management unit 2712 reconstitutes the file system using the DSM-CC 1704d according to the DSM-CC format, and stores the file number in the primary storage unit 1308. Data extraction such as a file file of a TS packet in an MPEG-2 driver stream and saving the data in a storage medium such as the primary storage unit 1308 and the secondary storage unit 1307 hereafter called the upload. Figure 23 shows an example of an overloaded file system. In the diagram, a circle represents a directory and a square represents a file. 2301 It is a root directory, 2302 is a "a" directory, 2303 is a "b" directory, 2304 is a "TopXlet .class" file, 2305 is a "GameXlet. Class" file, 2306 is a "z" directory , 2307 ee a file "MueicXlet .claes" and 2308 ee a file "StudyXlet.claee". Deepuée, the application state management unit 2712 passes the Java program that will be executed to the Java VM 1703, from among the file systems that are loaded to the primary storage unit 1308. Here, when the name of the Java program will be executed is "a / TopXlet", the file "a / TopXlet .class", in which ".class" is added to the end of the name of the Java program, it is the file that will be executed. "/" There is a division of directory and file name, and with reference to figure 23, file 2304 is the Java program that must be executed. Deepuée, the 2712 application release management unit pays file 2304 to the Java VM 1703, and the file is executed, like a Java program, in the Java VM. In case the "delete" control information is specified, the Java program is terminated. Each time you receive an AIT with a new version of AIT, the application release management unit 2712 analyzes the AIT and changes the execution status of the Java program. In the following, the operation of the application delivery management unit 2712 is then described in the preamble when it is requested by the trick playback interval processing unit 2702 to change the setting of a Java program. The application status management unit 2712 provides, as a function for managing the execution status of Java programs, a function of pausing a Java program corresponding to a specified Java program identifier, and a function of resuming the paused Java program . More specifically, the application status management unit 2712 provides a method "pause (int appID)" to pause a Java program, and a method "resume { Int appID)" to run the paused Java program again . Here, appID is the Java program identifier. When the trick play interval processing unit 2702 invokes the pause method, the application management unit 2712 paves a Java program that maps to a specified Java program identifier as an argument. For example, ei ee pauses (503), the application state management unit 2712 pauses a Java program that correepon to a Java program identifier of "503". When the trick play interval processing unit 2702 invokes the resume method, the application release management unit 2712 resumes a Java program corresponding to a Java program identifier specified as an argument. For example, if resume (503) is invoked, the application health management unit 2712 resumes a Java program that maps to a Java program identifier of "503". The JMF 1704a handles the control of video and audio playback contained in the service. To be more specific, the JMF 1704a integrates the video ES and the audio multiplexed into the specified channel of the specified MPEG-2 tranent stream., in the AV decoder for playback. In case the service reproduces directly from the received transmission wave, it is instructed to reproduce the transport stream MPEG-2 sent from the adapter 1311. On the other hand, in case the service that has been stored is reproduced a Once in the secondary storage unit 1307, it is instructed to reproduce the MPEG-2 transport stream sent from the recording area 1504 in the secondary storage unit 1307. First, the JMF 1704a searches for channel information in the library 1701b with a channel identifier specified as a key, and acquire a program number. Afterwards, using the SF 1704e and eimilaree, a PAT is acquired from the MPEG-2 driver stream. Then, the PID of the PMT that corresponds to the program number acquired is obtained from the information of the PMT. Again, using the SF 1704e, the actual PMT is acquired. The acquired PMT is in the format as shown in Figure 11, and has the current and elementary PIDs that have "video" and "audio" as the current types. When the JMF 1704a sets these PIDs on the PID filter 1502 of the TS 1302 decoder, the video ES and the audio ES multiplexed with PIDe eetoe are reproduced through the AV 1303 decoder, as shown in Figure 15 or Figure 16. Here, in case JMF 1704a receives, as an input, an MPEG-2 transport stream that has already been recorded in the secondary storage unit, the JMF 1704a can change the playback speed of video and audio to changing the reading speed and reading reading of the MPEG-2 driver stream of a storage area 1707 of the secondary storage unit 1307. Thus, trick playback such as forward and skip is possible. For example, if an MPEG-2 transport stream is read at twice the normal speed, video and audio are also played at twice the speed.

In addition, the MPEG-2 transport stream is read while only a specific time interval is being erased, video and audio are reproduced while only a specific time interval, video and audio are played while skipping. By using the function of the library 1701b, the JMF 1704a controls the secondary storage unit 1307 and changes the reading speed and reading reading in an MPEG-2 driver stream. Since the method for carrying out this trick reproduction euavely and at a high level is beyond the scope of the present invention, the description thereof is omitted. For a Java program to teach trick playback, the MF 1704a provides an API such as setRate (float factor), to the Java program. When 1.0 is set for a parameter factor, playback at normal speed is performed, and when 2.0 is set, trick playback is performed at twice the speed. In addition, in the event that a Java program instructs trick playback through an API, JMF 1704a parses the anteplay speed of the trick playback inelay and the playback speed after that inefficiency to the unit of determination. start / end of trick play 2701 of the trick play manager 1704g. By having a channel identifier, start time, and end time as entries, the recording manager 1704h writes the service to the secondary storage unit 1307, only during the time period between the start time and end time of the specified service. . For example, in EPG 1702 specifies the channel identifier, start time and end time, recording manager 1704h repoea haeta that the start time arrives. After eeo, it starts recording the specified service when the start time is reached, and stops recording when the end time is reached. The details are outlined below. At the recording start time, the recording management 1704h first assures, within the secondary storage unit 1307, a recording area 1504 to record the MPEG-2 transport stream from the start time to the end time specified in the secondary storage unit 1307. A media identifier is supplied to the recorded recording area. Deepuée, with the channel identifier as a key, the recording manager 1704 obtains tuning information corresponding to the channel information channel identifier contained by the library 1701b. After that, when the recording manager 1704h supplies the tuning information to the Tuner 1704c, the Tuner 1704c starts to tune. Here, the information of information tuning in which a frequency, a modulation format and similar can be specified. Afterwards, as shown in FIG. 15, the transport stream MPEG-2 is incremented in the TS decoder by means of the adapter 1311. Meanwhile, with the SF 1704e, the recording administrator 1704h acquires the PAT of the current of MPEG-2 transport obtained through tuning. In addition, it searches the library 1701b to find the program number that corresponds to the specified channel identifier, and it also searches the PAT to find the PID of the PAT that corresponds to the program number obtained. Deepuée of that, using the SF 1704e, acquires the real PMT for de eeta way to obtain all the PlDe of the ESs that constitute the specified channel. The recording manager 1704h sets the PIDs obtained to the PID filter 1502 of the TS decoder. Still further, an output of each hardware element is established through the library 1701c in order to follow the recording operation of the service included in the transmission wave in the secondary storage unit 1307. Afterwards, according to with the flow explained in figure 15, all the ESs that constitute a dedicated channel are recorded in the recording area 1504 that has been secured. After that, when the specified end time is reached, the recording manager 1704h stops the tuning operation of the tuner 1704c, and causes the writing of the MPEG-2 tranent stream to finish in the recording area 1504. In addition, a recording information management table as shown in figure 21 ee created as management information of the MPEG-2 driver stream that has been recorded previously. Fig. 21 is an example of the recording information management table for administering recorded recording information in the recording area 1504 of the secondary storage unit 1307 and the like. The recording information is recorded in graphic format. A column 2101 shows recording identifiers. A column 2102 shows channel identifiers. A column 2103 shows program numbers. A column 2104 shows recording start times for reelection service, and a 2105 column shows recording end times for services. A column 2106 identifies the media that identifies MPEG-2 transport streams that are recorded as an eService. Each of the rows 2111 to 2112 is a group of each recording identifier, channel identifier, program number, start time, end time and media identifier. For example, row 2111 shows a recording ID of "000", a channel identifier of "2", a program number of "102", a start time of "2005/03/30 11:00", one hour from the end of "2005/03/30 12:00", and one mediator identifier from "TS_001". The service administrator 1704f manages the reproduction of the service within the MPEG-2 driver stream that has been recorded in the secondary storage unit 1307, or the service within the MPEG-2 transport stream entered from the 1311 adapter. further, an operation is prescribed in the case of administering the reproduction of the service contained in the MPEG-2 tranent stream that has been recorded in the secondary storage unit 1307. This is equivalent to the reproduction of an already recorded service. In this case, the service administrator 1704f has the recording identifier as an entry. The service already recorded in the secondary storage unit 1307 and identified by that recording identifier will be reproduced. First, with reference to the recording information management table created by the recording manager 1704h, the service administrator 1704f obtains the channel identifier and the media identifier of the service to be reproduced, with the specified recording identifier. Then, through the library 1701b, the service administrator 1704f prompts the secondary storage unit 1307 to send, to the TS 1302 decoder, the MPEG-2 driver stream identified by the obtained media identifier. In addition, through the library 1701b, the service administrator 1704f establishes the output destination of each hardware component to flow through the path shown in FIG. 16. After ee, the secondary storage unit 1307 is provable. to JMF 1704a as the location of the MPEG-2 tranent stream, and the identifier of the service channel that will be reproduced from the source. Then, through the operation described above, the JMF 1704a begins playback of the multiplexed audio and video in the transport stream MPEG-2 sent from the secondary storage unit 1307. Deeper than that, the secondary storage unit 1307 is also provided to the AM 1704b as the location of the transport stream MPEG-2, and the channel identifier of the service that will be reproduced here. Then, according to the AIT multiplexed in the MPEG-2 trainer stream sent from the secondary storage unit 1307, the AM 1704b starts the execution and termination of the multiplexed Java program in the transport stream MPEG-2 sent from the storage unit secondary 1307. After that, the reproduction of the aforementioned service continues until the end of the transport stream MPEG-2 sent from the secondary storage unit 1307.

On the other hand, the problem of managing the reproduction of the service within the MPEG-2 transport stream entered from the adapter 1311 is described hereinafter. This is equivalent to reproducing the service directly from the transmission wave. In this case, the service administrator 1704f has the channel identifier of the service that will be reproduced as an entry. Through the library 1701, the service manager 1704f instructs the MPEG-2 transport stream sent from the adapter 1311 of figure 15 to be sent to the TS 1302 decoder. In addition, through the library 1701b, the administrator 1704f sets the output destination of each hardware element so that it flows through the path shown in FIG. 16. First, with the channel identifier as a key, the service manager 1704f obtains corresponding tuning information. to the channel identifier of the channel information contained by the library 1701b. After that, when the tuning information is given to the Tuner 1704c, the Tuner 1704c starts to tune. Here, the tuning information is information in which a frequency, a modulation format and the like can be specified. Deepuée de eeo, the adapter 1311 is provided to the JMF 1704a as the location of the MPEG-2 driver stream, and the channel identifier of the service to be reproduced is provided. Then, through the operation described above, the JMF 1704a begins playback of the multiplexed audio and video in the MPEG-2 driver stream sent from the 1311 adapter. In addition, the 1311 adapter is also provided to the AM 1704b as the location of the the MPEG-2 driver stream, and the channel identifier of the service that will be reproduced is provieto. Deepuée, according to the multiplexed AIT in the MPEG-2 driver stream sent from the 1311 adapter, the AM 1704b begins the execution and termination of the multiplexed Java program in the MPEG-2 driver stream sent from the 1307 secondary storage unit Deepuée of that, the reproduction of the service continues until the end of the transport stream MPEG-2 sent from the secondary storage unit 1307. The graphics 1704i provide a function to draw, in the plane of graph 1314, graph and inetruidoe to eer drawn by a Java program included in an e-service, through the library 1701b. It is implemented by the Java Abetract Window Toolkit (AWT) function. The graph drawn on the plane of graph 1314 is transferred to the visual presenter 1305 and presented in the same month with the appropriate frequency intro- duced by the CPU. The trick play manager 1704g monitors the trick playback performance of a service that is currently being reproduced, and instructs the AM 1704b to control a Java program included in the service in accordance with the change in status. Figure 27 is a diagram illustrating a detailed configuration of the trick play manager 1704g. The trick play start / end determination unit 2701 determines the start and end of trick play such as forward, rewind, slow motion or pause. In case the JMF 1704a has changed the reading speed of a transport stream MP? G-2 in response to an application of a Java program, the trick play start / end determination unit 2701 has been notified of the read speed before the change and reading speed after the change of JMF 1704a, and determines the start or end of trick playback. In case the reading speed has been changed from 1.0 times the speed to a speed higher or slower than 1.0 times speed, the trick play start / end determination unit 2701 determines the start of the playback of trick, while in case the reading speed has changed from a higher speed or lower than 1.0 times the speed to 1.0 times the speed, it determines the end of the trick playback. For example, if the reading speed of a transport stream MP? G-2 has been changed from 1.0 times the speed to 2.0 times the speed, the trick play start / end determination unit 2701 determines that the reproduction of Trick has started. Conversely, if the reading speed of an MPEG-2 transport stream has been changed from 2.0 times speed to 1.0 speed times, the trick play start / end determination unit 2701 determines that the trick play it is finished. If the re-evaluation of the determination is already the start or end of the trick play, the trick play start / end determination unit 27O1 parses the re-evaluation of the determination to the replay interval processing management unit. trick 2703. Trick play interval processing management unit 2703 instructs the trick play interval 2702 to perform trick play start / end processing for the Java program, with baee in the a determination made by the trick play start / end determination unit 2701 or the updated AIT reported by the AIT 2711 monitoring unit. More specifically, the trick play interval processing management unit 2703 passes a Java program identifier to be processed and a trick play indicator value to the unit processing of trick play intervals 2702 to carry out the processing. First, descriptions are given below of the case in which the trick play interval processing management unit 2703 intrudes to the trick play interval processing unit 2702 to perform trick play start / end processing in a Java program, based on the result of determination made by trick playback start / end determination unit 2701. The trick play interval processing management unit 2703 has itself a volatile memory for temporarily storing processing of trick playback interval that is a data line such as an indicator. When notifying of the determination reset of the trick play start / end determination unit 2701, the unit 203 first specifies a Java program identifier that correlates to a Java program that will be processed, with reference to the processing information of the program. trick reproduction interval contained in it. FIG. 41 shows an example of trick playback interval processing information contained in the trick playback interval processing delivery unit 2703. In FIG. 41, the columns 2201, 2204, 2205, and 4101 show an identifier of Java program, the corresponding program name, a paged indicator and a trick play indicator, respectively. A trick play indicator is an indicator that indicates whether or not the reproduction of an MPEG-2 transport stream is in a trick play mode at this time point. A trick play indicator value of "on" means that the play is in a trick play mode at this time point, while a trick play indicator value of "off" means that the playback is not on the trick play mode at this point of time. The trick play indicator ee updated with baee in the reported replay from the trick play start / end determination unit 2701. To be more specific, when the trick play start / end determination unit 2701 determines that trick play has started, the trick play indicator value is updated to "on", whereas when it determines that the trick play has ended , the trick play indicator value is updated to "off".

The paused indicator is an indicator that indicates whether the corresponding Java program is going to be paused or not during the trick play operation. The paced flag value of "true" means that the corresponding Java program will be paired during trick playback. For example, when referring to Figure 41, since a Java program "/ a / TopXlet" that corresponds to an identifier of the Java program of "301" has a value of "true", the Java program is paced during the trick reproduction. The trick play interval processing management unit 2703 specifies a Java program identifier to be passed to the trick play interval processing unit 2702, based on the paused indicator mentioned above. More specifically, the trick play interval processing management unit 2703 passes, to the trick play interval processing unit 2702, the Java program identifier with the paused indicator value of "true" being set, together with the trick play indicator value. For example, referring to Figure 41 here, the Java program indicator with the paged flag value of "true" is "301". In case the trick play start / end determination unit 2701 determines that trick play has started, the trick play interval processing management unit 2703 paea, to the play interval processing unit of trick 2702, the result indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier, and intrudes on the play interval processing unit of trick 2702 carry out processing to pause the Java program that corresponds to that Java program identifier. In the event that the trick play start / end determination unit 2701 determines that the trick play has ended, the trick play interval proceeding unit 2703 passes to the reproduction interval processing unit. of trick 2702, the result indicating that the trick play has concluded, in particular, the indicator value of trick play "off", as well as the Java program identifier, and instructs the play back processing unit of trick 2702 carry out processing to resume the Java program that has been paused and that corresponds to that Java program identifier. Below are descriptions below of the case in which the trick play interval processing management unit 2703 instructs the trick playback interval processing unit 2702 to perform trick play start / end processing in a Java program, with updated AIT notification in the AIT 2711 monitoring unit. FIG. 28A or FIG. 28B shows an example of a notified AIT from the AIT 2711 monitoring unit of AM 1704b. Each time an AIT is updated, the AIT 2711 monitoring unit notifies the updated AIT 2703 trick play interval management unit. First, in order to determine whether the paused indicator value has been changed, the trick playback interval processing management unit 2703 saves trick playback interval processing information that includes the paced indicator value at that time point in a volatile memory before the update. Next, the trick play interval processing management unit 2703 analyzes the notified AIT, and updates a paused indicator corresponding to each Java program in trick play interval processing information contained in the processing processing unit of the trick. trick play intervals 2703. For example, in case the AIT shown in Figure 28B is detected after the AIT shown in Figure 28A was detected by the AIT monitoring unit 2711, a paused indicator value corresponding to the Java program identifier of "301" in the trick play interval processing information contained in the trick play interval processing management unit 2703 is updated from "true" to "false". When the trick playback interval processing information was updated, the trick play interval processing management unit 2703 compares the paused indicator value stored in the volatile memory and the indicated value paused in the interval processing information of trick playback, and determines Java programs that have the flagged value changed by the update. If the paced indicator value has not changed, nothing is done. If the paced indicator value has changed, the trick play interval processing management unit 2703 contains the changed value, and then determines whether the trick play is in progress or not in progress at the present time based on the play flag. trick playback in trick play interval processing information. If the trick play indicator value is "off", in particular the trick play is not in progress at the current time, and nothing is done. If the trick play indicator value is "on", in particular the trick play is in progress at the present time, the trick play interval processing proceeding unit 2703 determines whether the paused flag value has been changed from "true" to "false", or from "false" to "true". In the first case, in particular in case the paused indicator value has been changed from "true" to "low", the trick playback interval 2703 proceeding unit proceeds, to the interval processing unit of trick play 2702, the result indicating that the trick play has completed, in particular, the trick play indicator value of "off", as well as the Java program identifier corresponding to the paused indicator, and instructs the unit of processing of trick play interval 2702 carry out processing to resume the Java program that has been paired and that correeponda to eee Java program identifier. In the second case, in particular in case the paused indicator value has been changed from "false" to "true", the trick play interval processing management unit 2703 paea, to the interval processing unit of trick play 2702, the reverb indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier that corresponds to this paused indicator, instructs the unit Processing Trick Playback Interval 2702 carry out processing to pause the Java program that corresponds to that Java program identifier. The trick play interval processing unit 2702 receives the Java program identifier to be processed and the trick play indicator value from the trick play interval processing management unit 2703, and performs appropriate processing for the Java program that correeponda to that identifier of Java program. If the trick play indicator value ee "on", the trick play interval processing unit 2702 invokes, using the Java program identifier as an argument, a pause method provided by the application state management unit 2712, and instructs to pause the Java program that corresponds to that Java program identifier. Conversely, the trick play indicator value is "off", the trick play interval 2702 invokes the processing unit, using the Java program identifier as an argument, a resume method provided by the application manager administration unit. 2712, and restart the Java program that corresponds to this Java program identifier.

For example, referring to FIG. 41, in which case the trick play interval processing management unit 2703 passes the Java program identifier of "301" and the trick play indicator value of "on" to the trick play interval 2702 processing unit, the trick play interval processing unit 2702 invokes, by using the Java program identifier of "301" as an argument, the method is projected by the state management unit of application 2712 in the AM 1704b, and it is not necessary to pause a Java program of "/ a / TopXlet" that corre- sponds to the Java program identifier of "301", to pause the Java program of "/ a / TopXlet" that corresponds to the identifier of Java program of "301". In case the trick play interval processing management unit 2703 passes the Java program identifier of "301" and the trick play indicator value of "off" to the trick play interval processing unit 2702, the trick play interval processing unit 2702 invokes, using the Java program identifier of "301" as an argument, the resume method provided by the application release management unit 2712 in the AM 1704b, instructs resumption a Java program of "/ a / TopXlet" that corresponds to the Java program identifier of "301", in order to resume the Java program of "/ a / TopXlet" that corre- sponds to the Java program identifier of "301". The EPG 1702 is an Electronic Program Guide, and is a function that allows a user to select a TV program that will be recorded and played back. Normal reproduction after receiving a transmission wave is outside the scope of the present invention and thus its description is omitted. In case of recording the TV program, EPG 1702 pre-dates a list of broadcast TV programs, and allows the user to select a desired TV program. Figure 19 shows an example of a screen pre-timer to allow selecting a TV program that will be recorded. One hour 1901 and channels 1902 and 1903 are presented on a grid, and it is possible to reviee the TV program of each recordable channel every hour. It is possible for the user to move a focus 1911 within the screen by pressing cursor up, down, right and left 1401 to 1404, which are included in the input unit 1310 of the terminal apparatus 1300. Also, when a button is pressed OK 1405, the TV program that is currently highlighted is selected to be recorded. The EPG 1702 acquires the channel identifier of the TV program of the library, and when the TV program that will be recorded is selected by the user, it notifies the channel identifier, start time and end time of the TV program to the administrator. of recording 1704h. Based on this information, the recording manager 1704h records the TV program in the secondary storage unit 1307. On the other hand, in case of reproducing a program of TV already recorded, the EPG 1702 visually presents a list of already recorded TV programs, and allows the user to select a TV program. Figure 18 is an example of a visual screen presenter to track the selection of an already recorded TV program. All TV programs stored in the secondary storage unit 1307 at that time point are arrived. It is possible for the user to move a focus 1801 within the screen when the cure button is raised up and down 1401 and 1402, which are included in the input unit 1310 of the terminal apparatus 1300. Furthermore, when the OK button 1405 is Pressed, the TV program that is currently highlighted ee selects to be played. The EPG 1702 acquires the recording identifier of the recording manager's TV program 1704h, and when the TV program to be reproduced is selected by the user, it notifies the service administrator 1704f of the recording identifier of the TV program. With the help of this information, the service manager 1704f reads the TV program of the secondary storage unit 1307 and plays it.

A typical operation is described below using a flow diagram in the present embodiment having the configuration explained above. Fig. 29 is a flow diagram showing the case of reproducing a service within an MPEG-2 transport stream recorded in the secondary storage unit 1307. First, a user instructs the EPG 1702 to play a service within a stream of transport MPEG-2 (S2901). In this way, the service manager 1704f is given an instruction to reproduce the service within the MPEG-2 transport stream recorded in the secondary storage unit 1307, and the recording identifier that identifies this service. Deepuée, the e-service manager 1704f intro- duces the JMF 1704a to play video and audio within the MPEG-2 driver stream recorded in the junior storage unit 1307, and the JMF 1704a starts playing the video and audio (S2902). In addition, since the service administrator 1704f intro- duces the AM 1704b to detect an AIT within the MPEG-2 transport stream recorded in the secondary storage unit 1307, the AIT 2711 monitoring unit of the AM 1704b begins detecting an AIT ( S2903). Here, if an updated AIT is detected, the corresponding Java program is controlled with baee in the control information in the AIT. { S2904). As for the Java program specified with "autostart" control information in the AIT, the application state management unit 2712 of AM 1704b initiates that Java program (S2905). As for a specified Java program with "delete" control information in the AIT, the application state management unit 2712 of the AM 1704b terminates that Java program (S2906). Deepuée, the AIT 2711 monitoring unit of the AM 1704b notifies the trick play interval requesting processing unit 2703 in the updated trick play manager 1704g of the updated AIT (S2907). Figure 28A and Figure 28B each show an example of an AIT. Each time an AIT is updated, the AIT 2711 monitoring unit notifies the updated AIT 2703 trick play interval management unit. The trick playback interval processing management unit 2703 analyzes the notified AIT, and updates a paused indicator corresponding to each Java program in trick playback interval processing information contained in the interval processing administration unit. trick play 2703. For example, in case the AIT shown in Figure 28B is detected after the AIT plotted in Figure 28A was detected by the AIT 2711 monitoring unit, a paced indicator value that correeponed to the identifier of the "301" Java program in trick playback interval processing information contained in the Trick Playback Interval processing unit 2703 ee updated from "true" to "false". Then, the trick play manager 1704g performs the processing depending on the update of the trick play interval processing information contained in the trick play interval 2703 (S2908). Eee procedure is described later. After that, the process returns to the AIT detection by the AIT 2711 monitoring unit (S2903). If an updated A.IT is not detected, the Java program is judged to have inruned trick play or not 20). Here, if the Java program invokes the eetRateO by a factor of "2.0", more specifically, if it does not reproduce trick, the JMF 1704a sets the speed to read the MPEG-2 driver stream from the secondary storage unit 1307 to the double the speed of the normal (S2910). If the trick play is not inetruye, proceeo returns to AIT detection by AIT 2711 monitoring unit (S2903). Then, the JMF 1704a notifies the trick play start / end determination unit 2701 in the trick play manager 1704g of the reading speed values of the MPEG-2 trance stream before and after the change of the speed (S2911). After that, the trick play manager 1704g performs the procedure depending on the change in the playback speed of the MPEG-2 driver stream (S2912). Eee processing is described later. After that, the process returns to the AIT detection by the monitoring unit of AIT 2711 (S2903). Fig. 30 is a flowchart illustrating a processing flow carried out by the trick play manager 1704g depending on a change in the playback speed of a MPEG-2 driver stream. In case that eetRateO is invoked by a program Java for eeta way to change a playback speed of a MPEG-2 driver stream, when the JMF 1704a notifies the trick play start / end determination unit 2701 in the trick playback manager 1704g of the before and after the change, the trick play start / end determination unit 2701 first determines whether the reproduction speed before the change is "1.0" or not (S3002). If the reproduction speed before the change is "1.0", the trick play start / end determination unit 2701 determines whether the playback speed after the change is "1.0" or not (S3002), and whether the speed after the change is not "1.0", determines that the trick play has started. Then, return the determination unit to the trick play interval processing unit 2703. If the playback speed after the change is "1.0", nothing is done. After receiving the result that the trick play has started, the Trick Play Interval processing unit 2703 determines whether or not there is a Java program identifier having a paused indicator value of "true" in the information. processing trick play interval contained therein 3003. Referring to Figure 41 here, the Java program identifier with the paced flag value of "true" ee "301". The stunt reproduction interval processing proceeding unit 2703 paea, to the stunt play interval 2702 processing unit, the replay indicating that the stunt play has started, in particular, the trick play indicator value of "on", ae as the Java program identifier, and instructs the trick play interval processing unit 2702 to carry out processing to pause the Java program corresponding to the Java program identifier (S3004). The stunt reproduction interval processing unit 2702 invokes, using the Java program identifier of between "301" as an argument, a pause method provided by the application state management unit 2712 in AM 1704b, and instructs pause the Java program that corresponds to that Java program identifier (S3005). If the reproduction speed before the change is not "1.0", the trick play start / end determination unit 2701 further determines whether the reproduction speed after the change is "1.0" or not (S3006), and whether the Playback speed after the change is "1.0", determines that the trick playback has ended. Deepuée, pars your determination result to the trick play interval 2703. If the playback speed after the change is not "1.0", nothing is done. After receiving the result that the trick reproduction has ended, the Trick Play Interval processing proceeding unit 2703 determines whether or not there is a Java program identifier having a paused indicator value of "true" in the information. for processing the trick playback interval contained therein (S3007). Referring to Figure 41 here, the Java program identifier with the paused indicator value of "true" is "301". The stunt reproduction interval processing unit 2703 passes to the trick play interval processing unit 2702, the replay indicating that the trick play has ended, in particular, the trick play indicator value of "off", ae as the Java program identifier, and intrude the trick playback interval processing unit 2702 to carry out processing to resume the Java program that has been paired and that corresponds to that Java program identifier (S3008 ). The Trick Play Interval Processing Unit 2702 invokes, using the Java program identifier of "301" as an argument, a resume method provided by the application release management unit 2712 on AM 1704b, and restart the Java program that has been paired and corresponding to the identifier of the Java program (S3009). FIG. 31 is a flowchart illustrating a processing flow carried out by the trick play manager 1704g depending on an update of trick playback interval processing information contained in the trick playback procedure management unit. trick play 2703. In the event that an updated AIT is detected, when the trick play interval processing information contained in the trick play 2703 ee updated processing step management unit is updated, the processing management unit of trick play intervals 2703 determines whether a paced flag value corresponding to any Java program has been changed or not (S3101). Here, in order to determine whether the paused indicator value has been changed or not, the trick play interval processing management unit 2703 stores trick play interval processing information that includes the indicator value paused at that time point. in a buffer before updating it. The trick play interval processing management unit 2703 compares the paused flag value stored in the buffer and the paused flag value included in the trick play interval processing information, and determines, based on the values before and after the update, if the paused indicator value has been changed or not. If the paused indicator value has not changed, nothing is done. If the paced flag value has been changed, the trick play interval processing management unit 2703 contains the changed value (S3102), and then determines whether the trick play is in progress at the current time based on the trick play indicator in the trick play interval processing information <; S3103).

If the trick play indicator value is "off", in particular the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", in particular, the trick play is in progress at the present time, the trick play interval processing unit 2703 determines whether the paced flag value has changed. from "true" to "faleo", or from "faleo" to "true" (S3104). In the second case, in particular in case the paused indicator value has been changed from "faleo" to "true", the trick play interval 2703 paea proceeding management unit, to the interval processing unit of trick play 2702, the result indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier corresponding to that paused flag, and instructs the trick play interval processing unit 2702 carry out processing to pause the Java program corresponding to eee Java program identifier (S3105). The trick play interval processing unit 2702 invokes, using the Java program identifier of "301" as an argument, a method of propagation by the application release management unit 2712 in the AM 1704b and prevents the pause of the Java program that corresponds to eee Java program identifier (S3106). In the first case, in particular in case the paused indicator value has been changed from "true" to "false", the trick play interval processing management unit 2703 paea, to the interval processing unit of trick play 2702, the reverb indicating that the trick play has completed, in particular, the trick play indicator value of "off", as well as the Java program identifier that corresponds to this paused indicator, and instructs the trick play interval processing unit 2702 carry out processing to resume the Java program that has been paused and corresponds to that Java program identifier (S3107). The stunt play interval processing unit 2702 invokes, using the Java program identifier of "301" as an argument, a resume method provided by the application state management unit 2712 in AM 1704b, and intrudes to resume the Java program that has been pained and that corresponds to eee Java program identifier (S3108). As described above according to the first modality, a Java program to which a paused indicator is set is delayed to a paeda effect during trick play, and thus it is possible to avoid unexpected behavior of the Java program during the play. trick reproduction.

Second Mode Hereinafter, an apparatus and a method according to the second embodiment of the present invention are described with reference to the figures. Since the hardware and similar configuration used in the second embodiment are the same as that of the first embodiment of the present invention, FIGS. 1 to FIG. 16 are again shown here since the constituent elements in these diagrams have the same functions that the constituent elements of the name and the same reference number in the first modality, are not repeated in descriptions. The software configuration of the second modality is the same as the one shown in Figure 17. Since the constituent elements that are not the AM 1704b and the trick play manager 1704g have the same functions as the constituent elements of the same names. and the same reference number in the software configuration of the first modality, they do not repeat the decree. Since various data formats used in the second modality are the same as those shown in FIG. 20 through FIG. 22 and FIG. 41, they are not repeated in any case. Figure 32 is a diagram illustrating a detailed configuration of the AM 1704b and the trick play manager 1704g in the Java 1704 library. The AM 1704b is configured from an AIT 2711 monitoring unit and an application status management unit. 2712. Since the application status management unit 2712 has the same functions as those of the first mode, the description is not repeated. The monitoring unit of AIT 2711 monitors the update status of AIT, using a MPEG-2 driver stream and a channel identifier as inputs, as in the first mode. In the first embodiment, if an AIT is updated, the updated AIT is notified to the trick play interval processing management unit 2703 and the trick play interval processing unit 2702. However, in the present embodiment , the updated AIT is notified only to the application release management unit 2712. Except for one operation of notifying the updated AIT trick 2703 reproduction processing interval management unit, the operations of the monitoring unit of AIT 2711 in the present modality is equal to the operation of the AIT 2711 monitoring unit of the first modality.

The trick play manager 1704g comprises a trick play start / end determination unit 2701, a trick play interval processing unit 2702, a trick play interval processing management unit 2703, and a unit of Trigger Play Interval Processing Information Privilege Determination 3201. Since the Trick Play Start / End Determination Unit 2701 and Trick Play Interval Processing Unit 2702 have respectively the same functions that in the first modality, they are not repeated sue decryption. As in the first embodiment, the trick play interval processing trick management unit 2703 contains trick play interval processing information in which trick play start / end processing is described for each Java program, and also instructs the trick play interval processing unit 2702 to perform trick play start / end processing for a suitable Java program based on that trick play interval processing information. In the first modality, if an AIT is updated, the updated AIT is notified of the monitoring unit of AIT 2711, and based on that AIT, a paused indicator in the information of reproduction of contained trick playback intervals is updated. However, in the present embodiment, even if the AIT is updated, the updated AIT is not notified from the AIT 2711 monitoring unit. The trick play interval processing management unit 2703 provides, as APIJava, a method "eetPaueingFlag (int appID, Boolean paueingFlag)" that has a paged flag value as an argument. Here, an appID argument is a Java program identifier that will be set with a paused indicator value, and a pausingFlag argument with a paced flag value. When the eetPaueingFlag method is invoked by a Java program, the flag paged in the trick playback interval information is contained and updated. For example, eetPaueingFlag (301, true) is invoked by a Java program, the paired flag that corresponds to a Java program that has a Java program identifier of "301" is set to "true". On the other hand, eetPaueingFlag (301, faleo) is invoked by a Java program, the paired indicator that corresponds to the Java program that has the Java program identifier of "301" is set to "faleo". When the setPaueingFlag method is invoked, the Trick Playback Interval Processing Provisioning Unit 2703 first passes the Java program identifier of the invoking Java program to the Trick Playback Interval Processing Privilege Determination Unit. 3201, to determine in this way the invoking Java program has a privilege, that is, a permission to update a paused indicator. The stunt reproduction interval processing information registration privilege unit 3201 regresses its determination result of whether or not the Java program to which the identifier was passed has a privilege of updating the paused indicator. If the determination result sent from the trick play interval processing information registration privilege unit 3201 indicates that the invoking Java program does not have a privilege to update the paused indicator, the interval processing management unit of trick play 2703 returns the fact to the invoking Java program. On the other hand, the re-evaluation of the determination indicates that the invoking Java program has the privilege of updating the paced indicator, the trick play interval processing trick management unit 2703 stores trick play interval processing information that includes the flag value paused at that time point in a buffer, and sets the paused flag value specified by the program Java in it. Deepuée, the Trick Play Interval processing procedure management unit 2703 determines whether or not the paired flag value corresponding to the Java program has changed. The stunt reproduction interval processing unit 2703 compares the paused indicator value stored in the buffer and the paced indicator value included in the trick playback interval processing information, and determines Java programs having the indicator value paused changed by the update. If the paused indicator value has not been changed, nothing is done. If the paused indicator value has been changed, the trick play interval processing management unit 2703 contains the changed value, and then determines whether the trick play is in progress at the current time based on the play indicator. trick playback in trick play interval processing information. If the trick play indicator value is "off", and in particular the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", in particular the trick play is in progress at the present time, the trick play interval processing management unit 2703 determines whether the paused flag value has been changed from "true" to "faleo" or from "false" to "true". In the first case, in particular in case the paused indicator value has been changed from "true" to "false", the trick play interval processing management unit 2703 passes, to the interval processing unit of trick play 2702 the result that indicates that the trick play has completed, in particular, the trick play indicator value of "off", as well as the Java program identifier corresponding to that paced flag, and intrudes on the unit processing trick playback intervals 2702 carry out processing to resume the Java program that has been pained and that correeponde to eee Java program identifier. In the second case, in particular in case the paused indicator value has been changed from "false" to "true", the trick play interval processing management unit 2703 paea, to the interval processing unit of trick play 2702, the reverb indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier that corresponds to that paced flag, and intrudes on the trick playback interval 2702 processing unit carry out processing to pause the Java program corresponding to that Java program identifier. The stunt reproduction interval processing information registration privilege unit 3201 determines whether or not the Java program corresponding to the specified Java program identifier has a privilege to update the paged flag in the interval information of the program. trick reproduction. After receiving the Java program identifier paired from the trick play interval processing management unit 2703, the trick play interval processing information registration privilege unit 3201 determines whether the corresponding Java program a eee Java program identifier has the permission to update the paced flag in the trick play interval processing information, and then, if you have the permission, allows the trick play interval processing management unit 2703 to update the paced flag in the trick play interval processing information. Here, the privilege, in particular the permission to update the indicator paused in the processing information of trick play intervals can be established, with, for example, MonitorAppPermission and similar in the specifications of the OCAP. This is a method in which a permission description file is also stored in a directory where a Java program is stored and a list of allowed privileges for the Java program is included in the permission description file. For example, if an application name of a Java program is written to a file called ocap.appilcationname.perm in a format such as <; ocap.-monitorapplication ñame = "eetPaueingFlag" valué = true > < / ocap: moitorapplication > , the Java program identified with this application name may have a privilege to update a paused indicator in trick play interval processing information. First, a Java program invokes a setPaueingFlag method provided by the trick play interval processing management unit 2703 in trick play manager 1704g, and asks to set the paused indicator value to the playback interval processing information of trick. The stunt reproduction interval processing management unit 2703 passes, to the stunt reproduction interval requesting information processing privilege unit 3201, the Java program identifier corresponding to the Java program invoking the method setPaueingFlag, for eeta way to determine whether or not that Java program has a privilege to update the paused indicator. Here, if the Java program does not have a privilege to update the paced flag, the trick play interval processing information registration privilege unit 3201 reregisters the event to the playback interval processing unit from trick 2703 and conclude the process. If the Java program has a privilege to update the paused indicator, the trick play interval processing information privilege determination unit 3201 returns the fact to the trick play interval processing management unit 2703. A typical operation in the present modality having the configuration explained above is described below using a flow chart. FIG. 33 is a flow diagram illustrating the point at which a Java program intrudes trick playback manager 1704g to update a paced flag in the trick play interval processing information. First, a Java program invokes a setPausingFlag method provided by the Trick Playback Interval processing proceeding unit 2703 in the trick play manager 1704g, and requests to set the flagged value to the playback information of the playback interval of the trick. trick. The stunt reproduction interval processing management unit 2703 passes, to the trick play interval processing information registration privilege unit 3201, the Java program identifier corresponding to the Java program invoking the method setPaueingFlag, in order to determine whether or not that Java program has the privilege of updating the paused indicator (S3302). Here, if the Java program does not have a privilege to update the paused indicator, the trick play interval processing information registration privilege unit 3201 returns the fact to the playback interval processing management unit. trick 2703 and conclude the process. If the Java program has a privilege to update the paced flag, the trick play interval cueing procedure registration information privilege unit 3201 resets the fact to the trick play interval processing management unit 2703, and establishes the paced indicator value specified by the Java program (S3303). Here, the trick play interval processing management unit 2703 determines whether or not the paled flag value corresponding to the Java program has been changed (S3304). Here, in order to determine whether the paced indicator value has been changed or not, the trick play interval processing management unit 2703 stores trick play interval processing information that includes the indicator value paused at that time point. in a buffer before updating it. The trick playback interval processing management unit 2703 compares the flagged value stored in the buffer and the flagged value included in the trick playback processing information, and determines, based on the values before and after the update, whether the paused indicator value has been changed or not. Here, if the paused indicator value has not been changed, nothing is done. If the paused indicator value has been changed, the trick play interval processing management unit 2703 contains the changed value (S3305), and then determines whether the trick play is in progress at the current time based on the trick play indicator in the trick play interval (S3306) processing information. If the trick play indicator value is "off", in particular if the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", in particular, the trick play is in progress at the current time, the trick play interval processing management unit 2703 determines whether the paced flag value has been changed. from "true" to "false", or from "false" to "true" (S3307). In the second case, in particular in case the paused indicator value has been changed from "false" to "true", the trick play interval processing management unit 2703 passes, to the interval processing unit of trick play 2702, the result indicating that trick play has initiated, in particular, the trick play indicator value of "on", as well as the Java program identifier corresponding to that paused flag, and instructs the trick play interval processing unit 2702 carry out processing to pause the Java program corresponding to that Java program identifier (S3308). The trick play interval processing unit 2702 invokes, using the Java program identifier of "301" as an argument, a pause method provided by the application state management unit 2712 in the AM 1704b and instructs to pause the Java program that correeponda a eee Java program identifier (S3309). In the first case, in particular in case the paced flag value has been changed from "true" to "false", the trick play interval processing management unit 2703 paea, to the interval processing unit of trick play 2702, the reverb indicating that the trick play has completed, in particular, the trick play indicator value of "off", as well as the Java program identifier that corresponds to that paced flag, and intrudes on the trick play interval processing unit 2702 carry out processing to resume the Java program that has been paused and corresponds to that Java program identifier (S3310). The trick play interval processing unit 2702 invokes, using the Java program identifier of "301" as an argument, a resume method provided by the application state management unit 2712 in AM 1704b, and instructs to resume the Java program that has been pached and corresponds to eee Java program identifier (S3311). Fig. 34 is a flow chart showing the failure to reproduce an operation within a MPEG-2 tracer stream recorded in the secondary storage unit 1307. First, a user instructs the EPG 1702 to reproduce a service within a stream of transport MPEG-2 (S3401). In this way, the service administrator 1704f is given an opportunity to reproduce the service within the MPEG-2 driver stream recorded in the secondary storage unit 1307, and the recording identifier that identifies that service. Then, the service manager 1704f instructs the JMF 1704a to play video and audio within the MPEG-2 transport stream recorded in the secondary storage unit 1307, and the JMF 1704a starts playing video and audio (S3402). In addition, since the service administrator 1704f intro- duces the AM 1704b to detect an AIT within the MPEG-2 driver stream recorded in the secondary storage unit 1307, the AIT 2711 monitoring unit of AM 1704b begins detecting an AIT ( S3403). Here, if an updated AIT is detected, the corresponding Java program is controlled with baee in the control information in the AIT (S3404). As for a specified Java program with "autostart" control information in the AIT, the application state management unit 2712 of AM 1704b starts the Java program (S3405). As for the specified Java program with "delete" control information in the AIT, the application state management unit 2712 of AM 1704b terminates that Java program (S3406). After that, the process returns to AIT detection by the monitoring unit of AIT 2711 (S3403). If an updated AIT is not detected, the Java program judges the trick play or not (S3407). Here, if the Java program invokes setRat () by a factor of "2.0", more typically, and intrudes trick playback, the JMF 1704a sets the speed to read the MPEG-2 driver stream from the secondary storage unit. 1307 at twice the speed of the normal (S3408). If the trick play is intruded, the process returns to the AIT detection by the AIT 2711 monitoring unit (S2903). Afterwards, the JMF 1704a notifies the trick play start / end determination unit 2701 in the trick play manager 1704g of the MPEG-2 tranent current reading rate value before and after the change in speed (S3409). Then, the trick play manager 1704g carries out the processing depending on the change in the playback speed of the MPEG-2 transport stream (S3410). Since the processing is the same as that of the first mode, the descriptions are not repeated with reference to FIG. 30. After that, the process reverts to AIT detection by the monitoring unit of AIT 2711 (S3403). As described above according to the second modality, a Java program to which a paused indicator is set is moved to a pae'e setting during trick playback, and in this way it is possible to avoid unexpected behavior of the Java program during playback. of trick. In addition, since a Java program sets a paused indicator, it is possible to control the paged indicator more flexibly than the indicator control paged by the AIT.

Third Mode Hereinafter, an apparatus and a method according to the third embodiment of the present invention are described with reference to the figures. Since the hardware configuration and similarly in the third modality is the same as that of the first embodiment of the present invention, Figure 1 to Figure 16 are again shown here. Since the constituent elements in this diagram have the same functions that the constituent elements of the name and the reference number in the first modality, are not repeated descriptions. The software configuration of the third mode is the same as the one shown in figure 17. Since the constituent elements that are not the AM 1704b and the trick reproduction manager 1704g and the graphics 1704i have the same functions as the constituent elements. of the same name and the reference numbers in the software configuration of the first modality, the descriptions are not repeated. Since several data formats in the third embodiment are the same as those shown in FIG. 20 through FIG. 21 except FIG. 22 and FIG. 41, they are not repeated. Figure 35 is a diagram showing detailed configurations of the AM 1704b, the trick playback manager 1704g and the graphics 1704i in the Java library 1704. The AM 1704b is configured of an AIT 2711 monitoring unit and the administration unit of state of applications 2712, as in the first mode. Since the monitoring unit of AIT 2711 has the same functions that in the first modality, its descriptions are not repeated. In the first embodiment, the 2712 application state management unit administers the Java program execution schedule by accepting an application of the trick play interval processing unit 2702 or by analyzing the details of the updated AIT passed from the AIT 2711 monitoring unit. However, in this modality, it manages the execution status of Java programs only by analyzing the details of the updated AIT passed from the AIT 2711 monitoring unit. Except an operation to accept the request of the trick play interval processing unit 2702, the AIT monitoring unit operations 2711 of the present embodiment are the same as the operations of the application state management unit 2712 in the first mode.

The trick play manager 1704g comprises the trick play start / end determination unit 2701, the trick play interval processing unit 2702, and the trick play interval processing processing unit 2703. Since the trick play start / end determination unit 2701 has the same functions as the first mode, are not repeated, but are deciphered. The stunt reproduction interval processing proceeding unit 2703 intrudes the stunt reproduction interval processing unit 2702 to perform trick playback start / end processing in the Java program, based on the determination result. made by the trick play start / end determination unit 2701 or the updated AIT reported by the AIT 2711 monitoring unit. More specifically, the trick play interval processing management unit 2703 passes to the program identifier Java to be processed and a trick play indicator value to the trick play 2702 processing unit in such a way as to cause it to process them. First, descriptions are given below of the case in which the trick play interval processing management unit 2703 instructs the trick play interval processing unit 2702 to perform trick play start / end processing. in a Java program, based on the result made by the trick play start / end determination unit 2701. When notified of the result of the determination from the trick play start / end determination unit 2701, the administration unit The stunt reproduction interval 2703 first identifies a Java program identifier that corresponds to a Java program that will be processed, with reference to the trick reproduction interval information contained therein. Fig. 42 shows an example of trick play interval processing information contained in trick play interval processing management unit 2703. In Fig. 42, columns 2201, 2204, 2205, and 4101 show program identifiers. Java, the corresponding program names, invisible indicators and a trick play indicator, respectively. A trick play indicator is an indicator that indicates whether or not the playback of a MPEG-2 driver stream is in a trick play mode at this point in time, as in the first mode.

An invisible indicator is an indicator that indicates whether or not the graphics drawn by a Java program are hidden during a trick playback. The "true" value of the unfeasible indicator means that the graphs drawn by the corresponding Java program are hidden in a trick play mode, and then when the trick play is canceled to revert to a normal play mode, the graph is hidden. drawn by the Java program they present visually again. The "false" value of the invisible indicator means that the graphs drawn by the corresponding Java program continue to be presented visually without being hidden in a trick playback mode. For example, referiree to Figure 42, since a Java Va / Topxlet program "corresponding to a Java program identifier" 301"has an unrealizable" true "indicator value, the graphs drawn by the Java program are hidden during trick playback The trick play interval processing management unit 2703 specifies the Java program identifier that will be passed to the trick play interval processing unit 2702, based on the invieible indicator mentioned above. specifically, the trick play interval processing management unit 2703 passes the Java program identifier with the invisible "true" indicator value set to the trick play interval 2702 along with the indicator value of trick playback, for example, by referring to figure 42, here, the Java program identifier with the value r unviable indicator of "true" ee "301". In case the trick play start / end determination unit 2701 determines that trick play has started, the trick play interval processing unit 2703 paea, to the play interval processing unit. of trick 2702, the reverb indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier, and inetrue the reproduction intervals processing unit of trick 2702 carry out processing to hide the graph drawn by the Java program. In the event that the trick play is terminated, the trick play interval processing management unit 2703 passes, to the trick play interval processing unit 2702, the result indicating that the trick play has ended. , in particular, the trick play indicator value of "off" as well as the Java program identifier, and instructs the trick play interval processing unit 2702 to carry out processing to visually present again the graphics drawn by that Java program. The following is a description of the situation in which the trick play interval processing management unit 2703 instructs the trick play interval processing unit 2702 to perform trick play start / end processing on a trick. Java program, based on the updated AIT reported from the AIT 2711 monitoring unit. Figure 36A and Figure 36B each show an example of a reported AIT from the AIT 2711 monitoring unit of AM 1704b. Since the Java program identifiers 2201, the control information 2202, the identifiers of DSM-CC 2203 and the program name 2204 of FIG. 36A and FIG. 36B are the same as those of the AIT of FIG. 22, they are not repeated the deecriptions. A column 3605 shows invisible indicators that correspond to respective Java programs. Each time an AIT is updated, the AIT 2711 monitoring unit notifies the updated AIT trick 2703 play interval management unit. First, in order to determine if the invisible indicator value has been changed, the trick play interval processing management unit 2703 stores trick play interval processing information that includes the invietable indicator value at that time point in a memory intermediate before updating it. Deepuée, in the Trick Play Interval Processing Provisioning Unit 2703, analyzes the notified AIT, and updates an unfeasible flag corresponding to each Java program in the trick play interval processing information contained in the same. For example, in case the AIT shown in FIG. 36B is detected after the AIT shown in FIG. 36A was detected by the AIT 2711 monitoring unit, the invietable indicator value corresponding to each Java program identifier of FIG. "301" in the trick play interval processing information contained in the trick play interval processing management unit 2703 is updated from "true" to "fake". When the trick playback interval processing information was updated, the trick play interval processing management unit 2703 compares the invisible indicator value stored in the buffer and the invisible indicator value in the interval processing information of trick playback, and determines Java programs that have the invietable indicator value changed by the update. Here, if the invisible indicator value has not changed, nothing is done. If the invisible indicator value has been changed, the Trick Play Interval Probe Management Unit 2703 contains the changed value, and then determines whether the trick play is in progress or not at the current time with baee in the trick playback in the trick playback interval processing information. If the trick play indicator value is "off", in particular the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", in particular the trick play is in progress at the present time, the trick play interval processing unit 2703 determines whether the unviable flag value has changed from "true" to "faleo", or "faleo" to "true". In the first case, particularly in the event that the invietable indicator value has been changed from "true" to "low", the trick play interval processing unit 2703 paea, to the interval processing unit of trick play 2702 the reverb indicating that the trick play is completed, in particular, the trick play indicator value of "off", as well as the Java program identifier that corresponds to this vietable flag, and instructs the unit 2702 Trick Play Interval Processing Process carry out processing to visually present the graphics drawn by the Java program that correepon to eee Java program identifier. In the second case, particularly in the event that the inadvertent indicator value has been changed from "false" to "true", the trick play interval processing management unit 2703 paea, to the interval processing unit of trick play 2702, the result indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier corresponding to that invisible flag, and instructs the Trick play interval processing unit 2702 carry out processing to hide the graphics drawn by the Java program that corresponds to eee program identifier. The trick play interval processing unit 2702 receives the Java program identifier that will be processed and a trick play indicator value from the trick play interval processing management unit 2703, and performs appropriate processing for the Java program that corresponds to that Java program identifier. If the trick play indicator value is "on" the trick play interval processing unit 2702 invokes, using the Java program identifier as an argument, an "invalid-te (int appID)" method provided by the unit of the graph plane filter 3502, and instructs to hide the graphs drawn in the plane of graph 1314 by the Java program that corresponds to the eee Java program identifier. Here, an appID argument is a Java program identifier. For example, ei ee invoke invalidate (301), graph e drawn in the plane of graph 1314 by the Java program that correeponda the identifier of Java program of "301" eon ocultoe. On the other hand, if the trick playback indicator value is "off", the trick play interval 2702 invokes, using the Java program identifier as an argument, a "validate (int appID)" method provided by the graphics plane filter unit 3502, and instructs to visually present again the graphics drawn on the graphics plane 1314 by the Java program corresponding to that Java program identifier. Here, an appID argument is a Java program identifier. For example, if validate (301) is invoked, graphics drawn on the graphics plane 1314 by the Java program corresponding to the Java program identifier of "301" are visually preened again. For example, with reference to FIG. 42, in case the trick play interval 2703 processing management unit pays the Java program identifier of "301" and the trick play indicator value of "on" to the stunt reproduction interval processing unit 2702, the stunt reproduction interval processing unit 2702 invokes invalidate (301) for eeta way to hide graphicse drawn by the Java program corresponding to the Java program identifier of "301" , and instructs to invalidate the graphics drawing in the graphics plane 1314 by the Java program. In case the stunt play interval 2703 processing proceeding unit passes the Java program identifier of "301" and the trick play indicator value of "off" to the trick play interval processing unit. 2702, the stunt reproduction interval processing unit 2702 invokes validate (301) for eeta way to visually preend again graphics drawn by the Java program corresponding to the Java program identifier of "301", and instructs to validate the drawing of graphics in the graphics plane 1314 by eee Java program. The graphics 1704i comprise the graphics drawing unit 3501 and the graphics plane filter unit 3502. The graphics plane drawing unit 3501 has a drawing function, by means of the library 1701b, graphics instructed to eer drawn by a Java program in the graphics plane 1314. This is implemented by the Java Astract Window Toolkit (AWT) function. The graphics drawn on the graphics plane 1314 are tracked and displayed on the old preeater 1305 with appropriate frequency, according to an input from the CPU 1306. The graphic plane filter unit e 3502 provides a function to invalidate or validate the graphic drawing is on the graph plane 1314 by the Java program that corresponds to the Java program identifier paired from the trick play interval processing unit 2702. To be more specific, the graphics plane filter unit 3502 erases the visual presentation of the graphics by the specified Java program of the pre-eater 1305. When the trick play interval 2702 invokes an invalidating method by using the Java program identifier as an argument, the graph plane filter unit 3502 invalidates the graph drawing on the graph plane 1314 by the Java program that corresponds to the Java program identifier. When the stunt reproduction interval processing unit 2702 invokes a validate method using the Java program as an argument, the graphics plane filter unit 3502 validates the graphics drawing on the graphics plane 1314 by the corresponding Java program to eee Java program identifier. Since the graphic drawing on the graphics plane 1314 by a specific Java program is invalidated during trick playback and validated during normal playback, according to an instruction from the trick play 2702 processing unit, The graphics instruction that will be drawn by the Java program is hidden from the pre-eater 1305 during trick playback. Since a workflow in case a service is reproduced within an MPEG-2 transport stream recorded in the secondary storage unit 1307 is the same as that shown in the flow chart of Figure 29 in the first mode, also reference is made here to figure 29 and the descriptions are not repeated. Fig. 37 is a flow diagram showing a processing flow carried out by the trick play manager 1704g depending on a change in the reproduction speed of an MPEG-2 transport stream. In the event that setRateO is invoked by a Java program to thereby change a playback speed of an MPEG-2 transport stream, when the JMF 1704a notifies the trick play start / end determination unit 2701 in the trick play manager 1704g of the playback rates before and after the change, the trick play start / end determination unit 2701 first determines whether the reproduction speed before the change is "1.0" or not (S3702). If the ante-change speed of the change is "1.0", the trick play start / end determination unit 2701 determines the playback speed after the change "ee" 1.0 or not (S3702), and the speed Playback After the change is not "1.0", it determines that the trick play has started. Then, match your determination result to the trick play interval processing management unit 2703. If the playback speed after the change is "1.0", nothing is done. After receiving the result indicating that trick play has started, the trick play interval processing management unit 2703 determines whether or not there is a Java program identifier that has an "untrue" value of "true" in the trick play interval processing information contained in itself (S3703). Referring to Figure 42 here, the Java program identifier with the invisible indicator value of "true" is "301". The trick play interval processing management unit 2703 passes, to the trick play interval 2702 processing unit, the replay indicating that the trick play has started, in particular, the trick play indicator value. of "on" as the Java program identifier, and it causes the trick playback interval processing unit 2702 to carry out processing to hide the graphics drawn by the Java program (S3704). The trick play interval processing unit 2702 invokes, using the Java program identifier as an argument, an invalidate method provided by the graphics plane filter unit 3502, and instructs to invalidate the graphics drawing in the graph plane 1314 for the Java program (S3705). If the playback speed before the change is not "1.0", the trick play start / end determination unit 2701 determines in addition to the playback speed after the change is "1.0" or not (S3706), and the playback speed after the change is "1.0", determines that The trick play is over. Then, it passes its determination result to the trick play interval processing management unit 2703. If the playback speed after the change is not "1.0", nothing is done. After receiving the result indicating that the trick playback has ended, the trick play interval processing manager unit 2703 determines whether or not there is a Java program identifier having an invisible indicator value of "true" in the trick reproduction interval processing information contained in itself (S3707). Referring to Figure 42 here, the Java program identifier with the invisible indicator value of "true" is "301". The trick play interval processing management unit 2703 passes to the trick play interval processing unit 2702, the replay indicating that the trick play has ended, in particular, the trick play indicator value of "off", ae as the Java program identifier, and intro to the trick play interval processing unit 2702 carry out processing to re-present again the graphics drawn by that Java program (S3708). The trick play interval processing unit 2702 invokes, using the Java program identifier as an argument, a validate method provided by the graphics plane filter unit 3502, and instructs to again validate the drawing of graphics on the plane of graphics 1314 by that Java program (S3709). Fig. 38 is a flow diagram showing a processing flow carried out by trick play manager 1704g depending on an update of trick play interval processing information contained in the trick play management unit trick play 2703. Figure 36A and Figure 36B each show an example of a reported AIT from the AIT 2711 monitoring unit of AM 1704b. Since the Java program identifiers 2201, the control information 2202, which is identified by DSM-CC 2203 and the program name 2204 of FIG. 36A and FIG. 36B are equal to the AIT of FIG. 22, they are not repeated. the descriptions. A column 3605 shows uninvited indicators that correspond to the re-selected Java program. An unviable indicator is an indicator that indicates whether or not the graph is drawn by a Java program during trick playback. The "true" value of the unfeasible indicator means that the graphics drawn by the Java program are hidden during trick playback. For example, referring to Figure 36A, since a Java program "/ a / TopXlet" that corresponds to a Java program identifier "301" has an unrealizable "true" indicator value, the graph is drawn by the Java program ee hide during trick playback. Each time an AIT is updated, the AIT 2711 monitoring unit notifies the updated AIT trick 2703 play interval administration unit. The Trick Play Interval processing proceeding unit 2703 analyzes the notified AIT, and updates an invisible indicator corresponding to each Java program in the trick playback interval processing information contained in the interval processing administering unit. of trick play 2703. For example, in case the AIT shown in Figure 36B is detected from the AIT shown in Figure 36A, it was detected by the AIT 2711 monitoring unit., the invisible indicator value corresponding to each Java program identifier of "301" in the trick play interval processing information contained in the trick play interval processing management unit 2703 is updated from "true" to "false". In case an updated AIT of that in FIG. 36A to FIG. 36B is detected, when the trick playback interval processing information contained in the trick playback interval processing proceeding unit 2703 is updated, the trick play interval processing management unit 2703 determines whether an invisible flag value has been changed or not (S3801). Here, in order to determine whether the invisible indicator value has been changed or not, the trick playback interval processing management unit 2703 stores the trick playback interval processing information including the indicator value invieible at that point. time in a buffer before updating it. The Trick Play Interval Probe Management Unit 2703 compares the unsafe indicator value stored in the buffer and the unfeasible indicator value included in the trick play interval processing information, and determines, with bae on the previously evaluated value. and after the update, if the invietable indicator value has changed or not. Here, if the invietable indicator value has not changed, nothing is done. If the invisible indicator value has been changed, the trick play interval processing proceeding unit 2703 contains the changed value (S3802), and then determines whether the trick play is in progress or not at the current time with baee in the trick play indicator in the trick play interval processing information (S3803). If the trick play indicator value is "off", particularly if the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", particularly if the trick play is in progress at the present time, the trick play interval processing management unit 2703 determines whether the invisible flag value has been changed. from "true" to "false", or from "false" to "true" (S3804). In the first case, in particular in case the invisible indicator value has been changed from "false" to "true", the trick play interval processing management unit 2703 passes, to the interval processing unit of trick play 2702, the result indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier corresponding to that invisible flag, and instruct the processing unit of trick playback interval 2702 carry out processing to hide the graph drawn by the Java program that corresponds to that program identifier (S3805). The trick play interval processing unit 2702 invokes, using the Java program identifier as an argument, an invalidate method provided by the graphics plane filter unit 3502, and instructs to invalidate the graphics drawing on graphics plane 1314 by the Java program (S3806). In the first case, in particular in the event that the invisible indicator value has been changed from "true" to "false", the trick reproduction interval processing proceeding unit 2703 paea, to the interval processing unit of trick play 2702, the result indicating that trick play has ended, in particular, the trick play indicator value of "off", as well as the Java program identifier corresponding to this vietable flag, and inetrue the trick playback interval 2702 proceed to perform the same procedure to display again the graphics drawn by the Java program corresponding to the Java program identifier (S3807). The trick reproduction interval processing unit 2702 invokes, using the Java program identifier as an argument, a validate method provided by the graph plane filter unit e 3502, and it is not possible to validate the graph drawing on the graph plane 1314 by the Java program (S3808). As described above, according to the third modality, the graphics drawn by a Java program are hidden during trick playback when an invisible indicator is set, and in this way it is possible to avoid the drawing of the graphics drawn during the reproduction of trick.

FOURTH MODE Hereinafter, an apparatus and a method according to the fourth embodiment of the present invention are described with reference to the figures. Since the configuration of hardware and the like used in the fourth embodiment are the same as those of the first embodiment of the present invention, figure 1 to figure 16 are again used here since the constituent elements in this diagram have the It should be the case that the constituent elements of the same names and the same reference number in the first modality, are not repeated. The software configuration of the fourth mode is the same as the one shown in figure 17. Since the constituent elements that are not the AM 1704b and the trick play manager 1704g have the same function as the constituent elements of the same name. and the same reference numbers in the software configuration of the third modality, the descriptions are not repeated. Since several data formats used in the fourth mode are the same as those shown in Figure 20 through Figure 21, Figure 36A, Figure 36B and Figure 42, their descriptions are not repeated. Figure 39 is a diagram showing detailed configurations of the AM 1704b and trick play manager 1704g in the Java library 1704. The AM 1704b is configured from the AIT 2711 monitoring unit and the application release management unit 2712 , as in the first modality. Since the monitoring unit of AIT 2711 has the same functions that in the second modality, there are no repeated descriptions. Since the application state management unit 2712 has the same functions as in the third mode, the descriptions are not repeated. The trick play manager 1704g comprises the trick play start / end determination unit 2701, the trick play interval 2702 processing unit, the trick play interval processing unit 2703, and the unit for trick playback interval processing proceeding privilege determination privileges 3201. Since the trick play start / end determination unit 2701 and the trick play interval processing unit 2702 respectively has the same functions that in the third modality, they are not repeated, but deciphered. As in the third embodiment, the trick playback interval proccessing administration unit 2703 contains trick playback interval processing information in which the trick playback start / end processing for a Java program describes , and also instructs the trick play interval processing unit 2702 to perform trick play start / end processing with baee in the trick play interval processing information. In the third modality, in an updated AIT, the updated AIT is notified of the AIT 2711 monitoring unit, and based on that AIT, an invisible indicator in the contained trick playback interval information is updated. However, in the current modality included in the updated AIT, the updated AIT does not notify from the AIT 2711 monitoring unit. The trick play interval processing management unit 2703 provides, like Java API, a method " setInvieibleFlag (int appID, Boolean invieibleFlag) "that has an invietable indicator value as an argument. Here, an appID argument is a Java program identifier that will be set with an unfeasible indicator value, and an inviable argument Fail is an unfeasible indicator value. When the setlnvisibleFlag method is invoked by a Java program, the unfeasible indicator in the contained trick play interval processing information is updated. For example, eetlnvieibleFlag (301, true) is invoked by a Java program, the invieible flag that corresponds to a Java program that has a Java program identifier of "301" is set to "true". On the other hand, eetlnvieibleFlag (301, false) is invoked by a Java program, the invieible indicator that correeponde to the Java program that has the Java program identifier of "301" ee set to "false". When the setInvieibleFlag method is invoked, the Trick Playback Interval processing proceeding unit 2703 matches the Java program identifier of the invoking Java program to the Trick Playback Interval processing procedure privilege determination unit 3201 , in order to determine if the invoking Java program has a privilege, that is, a permission to update an invisible indicator. The stunt reproduction interval processing information registration privilege unit 3201 regrees the re-determination of the Java program to which the identifier was paired has or has not a privilege to update the invisible indicator. If the result of the determination sent from the Trigger Play Interval Processing Privilege Privilege Determination Unit 3201 indicates that the invoking Java program does not have a privilege to update the invisible indicator, the trick play interval processing management unit 2703 returns the fact to the invoking Java program. On the other hand, if the result of the determination indicates that the invoking Java program has the privilege of updating the invisible flag, the trick play interval processing management unit 2703 stores trick play interval processing information that includes the invisible indicator value at that time point in a buffer, and sets the invisible indicator value specified by the Java program in the element. Deepuée, the Trick Play Interval processing proceeding unit 2703 determines whether or not the unvarying flag value corresponding to the Java program has been changed. The trick play interval processing management unit 2703 compares the invisible flag value stored in the buffer and the invisible flag value included in the trick play interval processing information, and determines, based on the values before and after the update, the invisible indicator value has been changed or not. If the invisible indicator value has not been changed, nothing is done. If the invisible indicator value has been changed, the trick play interval processing management unit 2703 contains the changed value, and then determines whether the trick play is in progress or not in progress at the current time based on the play indicator. trick playback in the processing information of trick playback interval. If the trick play indicator value is "off", and in particular the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", particularly if the trick play is in progress at the present time, the trick play interval processing management unit 2703 determines whether the invisible flag value has been changed. from "true" to "false" or from "false" to "true". In the first case, in particular in case the invisible indicator value has been changed from "true" to "false", the trick play interval processing management unit 2703 passes, to the interval processing unit of trick play 2702 the result indicating that the trick play has completed, in particular, the trick play indicator value of "off", as well as the Java program identifier corresponding to that unfeasible flag, and intrudes on the unit processing trick play intervals 2702 carry out processing to re-present again the graph drawn by the Java program corresponding to the Java program identifier. In the second case, in particular in case the invisible indicator value has been changed from "faleo" to "true", the trick play interval proceeding unit 2703 passes, to the interval processing unit of trick play 2702, the reverb indicating that the trick play has started, in particular, the trick play indicator value of "on", as well as the Java program identifier that correepone to this unfeasible indicator, and intrudes on the trick playback interval processing unit 2702 carry out processing to hide the graph drawn by the Java program that corresponds to the Java program identifier. The trick reproduction interval processing information privilege determination unit 3201 determines whether or not the Java program corresponding to the specified Java program identifier has the privilege of updating the unfeasible indicator in the interval processing information. trick reproduction. After receiving the last Java program identifier from the trick play interval processing management unit 2703, the stunt reproduction interval processing information registration privilege unit 3201 determines whether or not the Java program corresponding to that Java program identifier has permission to update the unfeasible indicator in the interval information of the program. trick playback, and then, if you have the permission, allows the trick play interval processing management unit 2703 to update the invisible indicator in the trick play interval processing information. Here, the privilege, in particular the permission to update the invisible indicator in the trick play interval processing information can be established with, for example, MonitorAppPermieeion and set in the OCAPspecification. Here is a method in which a permission description file is also stored in a directory where a Java program is stored and a list of allowed privileges for the Java program is included in the permieoe description file. For example, an application name of a Java program is written in a file called ocap.appilcationname.perm in a format such as <; ocap: monitor? plication ñame = "eetlnvieibleFlag" valué = true > < / ocap: moitorapplication > , the Java program identified with this application name may have a privilege of updating an invisible indicator in trick play interval processing information. First, a Java program invokes a setlnvieibleFlag method provided by the trick play interval processing management unit 2703 in the trick play manager 1704g, and requests to set the invisible indicator value in the playback information of the playback interval of the trick. trick. The stunt reproduction interval processing proceeding unit 2703 paea, to the trick reproduction interval processing information registration privilege determining unit 3201, the Java program identifier corresponding to the Java program invoking the method eetlnvieibleFlag, for eeta way to determine whether or not that Java program has a privilege to update the invisible indicator. Here, if the Java program does not have a privilege to update the invisible indicator, the trick play interval processing information registration privilege unit 3201 reregisters the fact to the playback interval processing unit from trick 2703 and concludes the proceeo. If the Java program has a privilege to update the inadvisable indicator, the trick play interval information processing privilege determination unit 3201 resets the fact to the trick play interval processing delivery unit 2703. A typical process in the present embodiment having the configuration explained above is described below using a flow diagram. Fig. 40 is a flowchart showing the loss in which a Java program intrudes trick playback manager 1704g to update an unfeasible flag in trick playback interval processing information. First, a Java program invokes an eetlnvieibleFlag method provided by the Trick Play Interval Probe Management unit 2703 in the Trick Play Manager 1704g, and requests to set an unfeasible indicator value in the reproduction information of reproduction intervals of trick (S4001). The trick play interval processing management unit 2703 paea, the trick play interval processing information privilege determination unit 3201, the Java program identifier corresponding to the Java program invoking the method setlnvieibleFlag, and determines whether or not the Java program has the privilege of updating the invieible indicator (S4002). Here, if the Java program does not have a privilege to update the invieible indicator, the trick play interval information processing privilege determination unit 3201 resets the event to the playback interval processing unit of the trick 2703 and conclude the process. If the Java program has the privilege to update the invisible indicator, the trick play interval processing information registration privilege determination unit 3201 regroups the fact to the trick play interval processing proceeding unit 2703, and establishes the invieible indicator value specified by the Java program (S4303). Here, the trick play interval processing management unit 2703 determines whether or not the invisible flag value corresponding to the Java program has been changed (S4004). Here, to determine if the unviable indicator value has been changed or not, the processing administration unit The trick play interval 2703 stores the trick play interval processing information that includes the invisible flag value at that time point in a buffer before updating it. The trick play interval processing management unit 2703 compares the invisible flag value stored in the buffer and the invisible flag value included in the trick play interval processing information, and determines, with baee in valuation before and after the update, if the invieible indicator value has been changed or not. Here, if the invisible indicator value has not been changed, nothing is done. If the inadvertent indicator value has changed, the Trick Playback Interval Probe Management Unit 2703 contains the changed value (S4005), and then determines whether the trick play is in progress or not at the current time with baee on. the trick play indicator in the trick play interval processing information (S4006). If the trick play indicator value is "off", particularly if the trick play is not in progress at the current time, nothing is done. If the trick play indicator value is "on", in particular, the trick play is currently in progress, the trick play interval processing management unit 2703 determines whether the invisible flag value has been changed. from "true" to "false", or from "false" to "true" (S4007). In the second case, particularly in the event that the invalid indicator value has been changed from "poor" to "true", the trick play interval processing unit 2703 paea, to the interval processing unit of trick play 2702, the result indicating that trick play has initiated, in particular, the trick play indicator value of "on", as well as the Java program identifier that corresponds to this unfeasible flag, and intrudes on the The trick reproduction interval 2702 proceed processing to hide the graph drawn by the Java program that corresponds to that Java program identifier (S4008). The trick playback interval processing unit 2702 invokes, using the Java program identifier as an argument, an invalidate method provided by the graph plane filter unit e 3502, and intrudes to invalidate the graph drawing in the graph plane 1314 by the Java program (S4009). In the first case, particularly in the event that the unverifiable indicator value has been changed from "true" to "low-level", the trick play interval processing management unit 2703 passes to the interval processing unit. trick play 2702, the result indicating that the trick play has concluded, in particular, the trick play indicator value of "off", as well as the Java program identifier corresponding to that invisible flag, and instructs the trick play interval processing unit 2702 carry out processing to present again the graphics drawn by a Java program corresponding to that Java program identifier (S4010). The trick play interval processing unit 2702 invokes, using the Java program identifier as an argument, a validate method provided by the graphics plane filter unit 3502, and instructs to again validate the drawing of graphics in the plane of graphics 1314 by that Java program (S4011). Since a process flow in lieu of reproducing a service within an MPEG-2 transport stream recorded in the secondary storage unit 1307 is equal to that shown in the flow chart of FIG. 34, reference is also made here to the figure 34 and the descriptions are not repeated. Since a processing flow carried out by the trick play manager 1704g depending on a change in playback speed of the MPEG-2 transport stream is equal to that of the third mode, the description is not repeated when referencing to figure 37. As outlined above according to the fourth modality, the graph drawn by a Java program is hidden during trick playback when an invisible indicator is set, and thus it is possible to avoid the graph drawing drawn during the trick reproduction. In addition, since a Java program establishes an unfeasible indicator, it is possible to control the inverter indicator more flexibly than the indicator controller inviable by AIT. Some of the modalities described above indicate the implementation examples of the present invention, but other modalities may be implemented as long as the objectives of the present invention are achieved. In the modalities, a configuration for a cable seventh has been shown, but the present invention can be applied independently of the type of a traceability system. For example, the present invention can easily be applied to a satellite system, a terreetree wave system or a TV program dielectricity which is an IP network. In addition, since the present invention has no direct relationship with the difference between the respective transmission systems, the present invention can apply to an arbitrary means of transmission notwithstanding the seventh transmission. The present invention is also applicable regardless of whether the seventh is a wired or wireless system. It is not necessary for the AV decoder to decode video and audio at the same time. The present invention can be implemented even if the AV decoder is configured as separate video and audio decoders. In addition, the AV decoder may have a decoding function for data such as subtitling and the like without any interference. The audio signal and video signal decoded by the AV decoder can be encrypted at any stage until they are stored in the recording area 1504. In the modes, an example is given in which an adapter that controls an access control conditional has been introduced, but the adapter is not always necessary for the implementation of the present invention. The adapter can have any format, and a configuration is also possible in the adapter. In such a case, in Figure 15, the MPEG-2 transport stream of the tuner is input directly into the TS decoder. The present invention is applicable in this case also. In addition, the randomization of the MPEG-2 driver stream by the adapter does not necessarily have to take place before the TS decoder. A configuration in which the adapter is in an arbitrary poem and designed to descramble the MPEG-2 transport stream is easily implementable, and the present invention is applicable in such a case as well. With respect to an encoding format in which the AV encoder encodes the audio and video signal, an arbitrary format is acceptable. The present invention is applicable not obeying the coding format. A multiplexer multiplexer format can also be an arbitrary format. The present invention is applicable not obeying the multiplexing format. The pre-eater and the loudspeaker may be contained within the recording and reproduction apparatus of the tranemieionee, or a preeater and external loudspeaker may be connected to the transmitter recording and reproducing apparatus. The present invention is applicable not obector of the location and number of the pre-eater and speaker. The present invention can be implemented even if the CPU itself is a seventh that performs varioe process, the processes being all or some of TS decoding, AV decoding, AV coding and multiplexing. As a format for recording the service, the MPEG-2 driver stream can also be recorded directly in the recording area after it has been sent from the tuner, without pacing through the TS decoder.; or, the format of the MPEG-2 transport stream from the tuner can be converted, by installing a translator that converts the MPEG-2 transport stream format, and recorded in the recording area. The present invention is applicable notwithstanding the service recording method. Some of Java's virtual machines translate the byte code into an executable form that can be interpreted by the CPU, and paean the output to the CPU running it; the present invention is applicable in such a case as well. The modalities of the previous modality establish a method for the implementation with respect to the AIT, in which the current of transportation is obtained from En Banda; However, the method to referiree to the Java program that the AM will have to execute does not depend solely on the AIT. In the OCAP that is assumed to be used in the seventh cable of Eetadoe Unidoe, an XAIT that deepens reference information of an application program is used in the OOB shown in figure 3. In addition, methods such as start of a pre-recorded program in the ROM, start a program downloaded and recorded in the secondary storage unit, and others can connect. Although only a few examples of this invention have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the teaching and novelties and sale of this invention. Therefore, all modifications are intended to be included within the scope of this invention.

INDUSTRIAL APPLICABILITY According to the recording and reproducing apparatus and the recording and reproducing method of the present invention, in case a terminal plays a recorded content with trick play fionality, an application program is shifted to a state of pauea, or the drawing of graphics by the application program is temporarily canceled, even if the application program is executing processing that consumes time, or even if the application program is being executed in a terminal with low processing power. Therefore, it is possible to control ineeperadoe behavior of the application program. In addition, it is possible, particularly during advance and rewind, to reduce high-load access to a semiconductor or similar memory represented by a hard-core die, a Blu-ray die (BD), a Digital Venetian Die (DVD), a memory card Secure Digital (SD) and eimilaree, and in this way reduce the deterioration of this storage medium. Therefore, it is highly possible that the present invention is used particularly in the consumer electronics industry which includes transmission recording and reproducing apparatus. For example, the present invention is applicable to STB by cable, digital TV and similar. Moreover, the present invention is also applicable in a device with a transmition reception fion, such as, for example, a cell phone device and eimilaree. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention.
