Abstract

A setup (a service manager 1704f or the like) for notifying a user that an application program is not executed due to a trick play in the case where the application is not executed for some reasons, during the trick play, in a synchronization interval during which the application is to be executed in synchronization with video/audio when normal reproduction is operated, and for starting the normal reproduction of a content from the start of the range within which the application is to be executed, in the case where the user desires the normal reproduction of the content during the trick play.

Description

APPARATUS AND METHOD PAHA THE RECORDING AND REPRODUCTION OF TRANSMISSIONS FIELD OF THE INVENTION The present invention relates to an apparatus for recording and reproducing transmissions that stores transmitted contents and reproduces the stored transmitted contents. In particular, the present invention relates to an installation for storing video, audio and data by receiving a transmission wave with which formed video, audio and data contents such as a program, which are mutually synchronized are multiplexed, as well as to a scenario for performing trick playback such as fast forwarding or rewinding the content while maintaining video, audio and data synchronization 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 REFs; 184011 data by fixed interval. In the first method of sending data chronologically, for example, data that continues over time is 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 data that could not be received due to synchronization of the shipment can not be received again. On the other hand, in the second method of repeatedly sending the data in 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 when the same data is being sent, any of the data pieces sent repeatedly can be received, and in this way the reception timing is not limited. The transmission of data, represented by BML, and the sending of files through a DSMCC 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 the reception fails after the synchronization of the sending and acquisition of the data fails, the data can not be reacquired. Therefore, when sending data such as an application program together with video and audio in the transmission wave, the method of repeatedly sending the data by fixed interval is favorable. Currently, the specifications for receiving a transmission wave that includes video, audio and an application program and running the application program in synchronization with video and audio, as in the previous method, have been developed and are in operation. It is possible to receive the application program sent, load the application program in a terminal and implement several additional functions when executing the application program, instead of simply watching the video and audio. This method for sending the application program and importing the application program into the terminal is also called "download". For example, a specification called the Digital Video-Multimedia Video Broadcasting Platform (DVB-MHP) ETSIES201812 vl.1.1 (2003-12) has been developed in Europe, and operations in accordance with this specification have already begun. In addition, the Open Cable Application Platform (OCAP), which provides the same specification in the cable broadcast environment in the United States, is being developed in the United States, and real operations are being prepared to begin. In these specifications, the application program is written in the Java language. Several Application Programming Interfaces (APIs) 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-I01-040524 specification is being developed, which is focused on adding a function to record and reproduce the contents in the OCAP specification. With this specification, the video, audio and the Java application program synchronized with them are executed, which are sent as a cable television transmission, recorded as content and also reproduced in the same way as when the recorded contents they are being reproduced directly from the transmission wave. The application program plays in synchronization with the video and audio, in the same way as the direct reproduction of the transmission wave. Furthermore, with OCAP-DVR, trick playback of the contents is achieved by recording transmission contents in a high-speed random access 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 fast forward, rewind, slow motion, pause, jump and the like. With OCAP-DVR, the application program imported into the terminal from the wave of Transmission can control the recording and trick playback of the contents. In other words, APIs for trick recording and playback are provided in the terminal, and the Java application program controls each function by invoking these APIs. Normally, in order for the application program to run in synchronization with the video and audio, control information for the synchronization is already multiplexed in the transmission wave. The application program is executed sequentially according to the synchronization control information and is finished. Thus, it is possible to run the application program by changing the program to an appropriate one according to a specific video and audio scene. Incidentally, in case of reproduction, in a trick play mode, a content recorded by a terminal based on the OCAP-DVR or similar, it is necessary to change the application program by an appropriate one according to the state of the trick play operation. For example, in case a video is changed by another video through fast forward, the application program that is associated with the synchronized video is also changed according to the video playback speed. In case of playing the content using a jump mode, the application program synchronizes with the position to start playing the video after the Jump operation is executed, for example. In the case of rapid advance of content, the terminal, in some cases, may not be able to execute the application program through the change according to the speed of fast forward playback. Such a case includes the case in which it takes time to activate the application program and the synchronization to activate the next application program arrives during the activation. In the OCAP-DVR specification, in consideration of such a case in which it is difficult to execute the application program in synchronization with video and audio during playback of the content in a trick play mode, an indicator is specified that executes a program of application during playback of the content in a trick play mode and an indicator that an application program does not play during playback of the content in a trick play mode. Here, these indicators can be specified by a content creator for each application, and in case the indicator that does not run an application program while playing the content in a trick play mode is set, even the application program that is to be played in a normal playback mode has to be terminated during the trick play operation of the content that this application program includes. It specifies that when the reproduction of the content is returned to a reproduction in normal reproduction mode, the application program has to be again executed in synchronization with the video and audio according to the control information. The Japanese translation of PCT International Patent Application No. 2003-513555 also defines "an application program with a configuration that allows the application program to be executed while playing a content in a trick play mode" and "an application program with a configuration that does not allow the application program to be executed while playing a content in a trick play mode". In the case of "an application program with a configuration that does not allow the application program to be executed while playing a content in a trick play mode", a system in which the application program is terminated during the reproduction of a content that includes that application and when the trick playback operation is finished, the application is activated again, and the control information of the application that has not been detected due to the execution of the operation of the playback mode of trick is notified to the application.

BRIEF DESCRIPTION OF THE INVENTION With the prescriptions defined in the OCAP-DVR specification, and the invention described in the Japanese translation of the PCT International Application No. 2003-513555, a content creator may previously specify that an application program does not must be executed while playing a content in a trick play mode. In this way, even in the case that the application program can not be executed in synchronization with video and audio due to the length of time to activate the application, the creator of the content can take steps as to not let the application be activated. However, with the prescriptions defined in the OCAP-DVR specification, and the invention described in the Japanese translation of the international PCT application No. 2003-513555, in the case where it is specified not to execute an application program during the reproduction of a content in a trick play mode, a problem is that an application program that will be executed during the normal playback operation is not executed during the trick play operation, and the observer may not know, during the reproduction in trick play mode, there is this application. Therefore, the observer who has operated the fast forward playback is not aware of the presence of the application that normally should be reproduced, and thus lose the opportunity to run this application. The present invention therefore provides a mechanism for notifying the viewer that an application is not executed because a content is being played in a trick play mode, in case an application program is not executed, due to some problem, in a synchronization interval during which the application program has to be executed in synchronization with video / audio at the time of the normal playback operation. In addition, in the event that the observer desires an execution of an application program during playback in the trick play mode, the present invention also provides a mechanism to initiate playback of the content in a normal playback mode from the start. of the scale within which the application must be executed. The present invention focuses, with these mechanisms, so that the observer can enjoy an application program synchronized with the video / audio included in a content without any application program being omitted, even if the reproduction is operated in the reproduction mode of trick.

DETAILED DESCRIPTION OF THE INVENTION First Mode Hereinafter, an apparatus and a method according to the first embodiment of the present invention will be described with reference to the figures. The present invention is focused on the recording and reproduction of content sent and received by an arbitrary means; however, in the present embodiment, a cable television transmission system is described as an example. In the cable television transmission system, a transmission recording and reproducing apparatus is generally called a terminal apparatus. Figure 1 is a block diagram showing a list of apparatuses constituting a transmission system; the transmission system is configured a transmission station side system 101 (distribution center), and a terminal apparatus there, a terminal apparatus B112 and a terminal apparatus C113. A coupling 121 between the transmission station side system 101 and each terminal apparatus is, in the cable system, a wired coupling such as a coaxial cable, a fiber optic cable and the like. In Figure 1, a transmission station side system is coupled with three terminal devices, but the number of terminal devices is arbitrary. The transmission station side system 101 sends information such as video / audio / data for the transmission of data in a transmission system to a plurality of terminal devices. The transmitted signal is sent using a frequency within a frequency band set by operational regulations of the transmission system and the laws of a country / region in which the transmission system is operated, and so on. With the cable system according to the present embodiment, the frequency band used in the transmission of transmission signals is divided into the data content and transmission direction (inward, outward) and then applied. Figure 2 is a graph indicating an example of the division of the frequency band. The frequency band is broadly divided into two types: out of band (abbreviation OOB) and In Band. 5MHz to 130MHz These are assigned as OOB, and are used mainly in the exchange of input / output data between the transmission station side system 101 and the terminal apparatus there, the terminal apparatus B112 and the terminal apparatus C113. 130MHz to 864MHz These are assigned as In-Band, and are mainly used in a single-output channel that includes video / audio. A QPSK modulation scheme with OOB and a modulation type QAM64 or QAM256 with In-Band is used. The technology of Modulation schemes are generally known and are of little concern for the present invention, and therefore their detailed description is omitted. Figure 3 is an example of a more detailed use of the OOB frequency band. 70 MHz to 74 MHz are used in output data that is sent from the transmission station side system 101, and all the terminal apparatuses. There, the terminal apparatus B112 and the terminal apparatus C113 receive the same data from the transmission side system. transmission station 101. On the other hand, 10.0 MHz to 10.1 MHz are used in the sending of input data from the terminal apparatus there to the transmission station side system 101; 10.1 MHz to 10.2 MHz are used in input data that is sent from the terminal apparatus B112 to the transmission station side system 101 and 10.2 to 10.3 are used in input data that is sent from the terminal apparatus C113 to the station side system transmission 101. Through this, it is possible to independently send unique data from each terminal apparatus there, B112 and C113 to the transmission station side system 101. Figure 4 is an example of use of the In-band frequency band. 150 MHz are assigned to 156 MHz and 156 MHz to 162 MHz to a TV channel 1 and a TV 2 channel respectively, and subsequently, TV channels are assigned at 6 MHz intervals. Radio channels are assigned in units of 1 MHz. MHz of 310 MHz and above. Each of these channels can be used as analog transmission or as digital transmission. In the case of transmitting a digital transmission, a TS packet format based on MPEG-2 specifications is used for transmission, and it is also possible to send data for the transmission of various data and composition information of TV programs to configure EPG, in addition to audio and video. The transmission station side system 101 uses the frequency bands described above to send a suitable transmission signal to the terminal devices, and therefore, has a modulation unit QPSK, a modulation unit QAM, and so on. In addition, the transmission station side system 101 has a QPSK demodulator to receive data from the terminal devices. In addition, the transmission station side system 101 can be thought of as having several devices related to the modulation units and the demodulation unit. However, the present invention relates mainly to terminal devices, and detailed descriptions are therefore omitted. Terminal devices There, B112 and C113 have a demodulation unit QAM and a demodulation unit QPSK in order to receive and reproduce a signal transmitted from the transmission station side system 101. In addition, each terminal apparatus has a QPSK demodulation unit. to be able to send the unique data to Transmission station side system 101. In the present invention, the end apparatuses are recording and reproducing apparatuses of detailed transmissions and configurations will be described later. The transmission station side system 101 modulates an MPEG-2 transport stream and transmits the current within the transmitted signal. The terminal devices receive the transmitted signal, demodulate the transmitted signal in order to reproduce the MPEG-2 transport current, extract necessary information from it, and use the information extracted. In order to describe the function and connection structure of a device present in the terminal apparatus, the structure of the MPEG-2 transport stream will first be described in a simple manner. Figure 5 is a diagram showing 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 501 has a length of 4 bytes, and a structure presented by 504. In the header 501 there is a field indicated "Package ID" (hereinafter, PID), and the TS packet is identified through the value of this 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 are cases in which the adaptation field 502 is not present. The payload 503 contains information carried in the TS packet, such as video, audio and data transmission data. Figure 6 is a schematic diagram of an MPEG-2 transport stream; the TS package contains various information in the payload, such as video, audio, data used for data transmission, alerts and the like. A TS 601 packet and a TS 603 packet contain a PID 101 in the header and contain information that refers to video 1 in the payload. A TS 602 packet and TS 605 packet contain a PID 200 in the header, and contain information that refers 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 payloads and transmitting these 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 PlDs contain identical types of information. Therefore, the terminal apparatus reproduces video and audio, data such as composition information of TV programs, upon receiving multiplexed TS packets and extract, by PID, the information contained in the TS packet. In Figure 6, the TS 601 packet and the TS 603 packet each transmit information that relates to the video 1, and the TS 602 packet and the TS 605 packet each transmit information that relates to the data 1. Here, it is gives a description that refers to a format of various types of data contained in the payload. Video and audio are represented by a format called a packet of Packed Elementary Stream (PES). The PES package includes video information and audio information of a certain period of time, and upon receipt of the PES packet, the transmission recording and reproducing apparatus 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 broadcast recording and playback apparatus to continuously play the video and audio without pause. When the PES packet is actually transmitted, the PES packet is divided and stored in the payloads of a plurality of TS packets in case the TS packet is larger than the payload of a TS packet. Figure 7 shows an example of division when a PES packet is transmitted. A PES 701 package is too large to be stored and transmitted on a load useful of a single TS package, and therefore the PES 701 package is divided into a PES A 702a package division, a PES B 702b package division and a PES C 702c package division, and is carried in three TS 703 packages to 705 which have identical PlDs. Actually, video and audio is obtained as an elementary stream (ES) that is obtained by concatenating data contained in the payloads of a plurality of PES packets. The elementary stream is in the form of digitized audio and video, as defined by the MPEG-2 video standards, the MPEG-1 and 2 audio standards, and the like. On the other hand, information such as the composition information of TV programs and data used 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 larger size than the payload of the MPEG-2. a TS package. Figure 8 shows an example of division when the MPEG-2 section is transmitted. Since an MPEG-2 801 section is too large to be stored and transmitted in a payload of a single TS packet, the MPEG-2 801 section is divided into a section division A 802a, a section division B 802b and a division of section C 802c, and it is carried in three packages TS 803 to 805 which have identical PIDs. Figure 9 presents a structure of this MPEG-2 section. An MPEG-2 900 section is structured by a header 901 and a payload 902. The header 901 contains control information of the MPEG-2 section. The composition of the header 901 is presented by a header structure 903. The payload 902 contains data transmitted by the MPEG-2 900 section. A table identifier (table_id, hereinafter) present in the header configuration 903 represents the type of the MPEG-2 section, and a table identifier extension (hereinafter, table_id_extension) is an extension identifier used when it is further distinguished between MPEG-2 sections, each having an identical table_id. The case of transmitting the composition information of TV programs is shown in figure 10 as an example of the use of the MPEG-2 section. In this example, as written in a row 1004, information necessary for demodulation of the transmission signal is written in the MPEG-2 section that has a table_id of 64 in the header configuration 903, and this MPEG-2 section is transmitted more for a TS packet with a PID of 16. The PES format does not exist in the case of the MPEG-2 section. For that reason, the elementary current (ES) is a concatenation of the payloads of the TS packets identified by the identical PIDs within the MPEG-2 transport stream. For example, in Figure 8, all TS 803 to 805 packets, in which the MPEG-2 801 section is divided and transmitted, are identified with the PID of 200. It can be said that this is an ES that transmits the section MPEG-2 801. A concept called a program also exists in the MPEG-2 transport stream. The program is expressed as a collection of ESs, and is used in case you want to manage a plurality of ESs all together. With the use of the program, it is possible to manage video / audio, as well as accompanying data transmission data, all together. For example, in the case of handling the video / audio that will be played simultaneously, by grouping the video ES and the audio ES as a program, it can be seen that the transmission recording and playback apparatus should simultaneously reproduce these two ESs like a TV show. To express the program, two tables, called a program map table (PMT) and a program association table (PAT) are used in MPEG-2. Detailed descriptions can be found in the specifications of ISO / IEC 13818-1, "MPEG-2 Systems". The PMT and the PAT are briefly described hereinafter. The PMT is a table included in the transport stream MPEG-2, in a number as much as that of the Program. 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 an ES that belongs to the program . An example of the PMT is given in Figure 11. 1100 It is a program number. The program number is assigned only to programs in the same transport stream, and is used to identify the PMT. The rows 1111 to 1115 express information referring to individual ESs. A column 1101 is a type of ES, in which "video", "sound", "data" and so on are specified. A column 1102 is the PID of the TS packets that make up the ES. A column 1103 is additional information that refers to the ES. For example, the ES shown in row 1111 is an audio ES, and is carried in the TS packets with a PID of 5011. The PAT is a table, of which only one is present in the MPEG-2 transport stream. . The PAT is configured as an MPEG-2 section, has a table_id of 0, and is carried in the TS packet with a PID of 0. The PAT contains a transport stream identifier (hereinafter, transport_stream_id) used for the identification of the MPEG-2 transport stream, and information that refers to all the PMTs that represent a program in the MPEG-2 transport stream. An example of the PAT is given in figure 12. 1200 Indicates a transport_stream_id. The transport_stream_id is used to identify the MPEG-2 transport stream. The rows 1211 to 1213 express information that refers to the program. A column 1201 indicates a program number. A column 1202 indicates the PID of the TS packet sent by the PMT corresponding to the program. 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 501. In case the terminal apparatus plays a certain program, the terminal apparatus specifies the video and audio that constitute a program, with reference to the PAT and the PMT, and reproduce that video and audio. For example, with respect to the MPEG-2 transport stream that transmits to the PAT in Figure 12 and the PMT in Figure 11, the following procedure is taken in case the video and audio belonging to the program with a number of 101 programs are reproduced. First, a PAT transmitted as 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 for a program with program number "101", and row 1211 is obtained. From row 1211, the "501" PID of the TS package transmitted by the PMT of the program with a program number is obtained " 101". Then, the PMT transmitted as an MPEG-2 section with a table_id of "2" is acquired from the TS packet with a PID of "501" Row 1111, which is audio information IS, and row 1112, which is video information ES, are obtained from the PMT. A PID "5011" of the TS packet transmitting the audio ES is obtained from the row 1111. In addition, a PID "5012" of the TS packet transmitting the video ES is obtained from the row 1112. Afterwards, a packet is acquired Audio PES of the TS packet with a PID "5011", and a PES pack of video of the TS packet with a PID of "5012" is acquired. Through this, it is possible to acquire the ES video and audio packages that will be reproduced, and the video and audio that constitute the program number 101 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 transmit certain video / audio information, only specific observers who can descramble them will be able to see that video and audio information. In order to descramble and watch the video and audio, an observer must descramble them using a device called a descrambler. For example, in a terminal apparatus compatible with OCAP, a card-type adapter with an integrated descrambler is used. A cable television operator distributes an adapter configured to be able to decrypt a specific program for each observer, and the observer inserts that adapter into the terminal apparatus. After doing so, the adapter descrambles the specific program based on descrambling information such as a descrambling key and contract information from each contract holder. A descrambling method, a method for obtaining the descrambling key and the like, are dependent on the adapter, and have no influence on the embodiment of the present invention. So far, simple descriptions have been provided with respect to the MPEG-2 specifications; hereafter, detailed definitions of the terminology are given. In the present invention, there are two types of term "program". 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". In addition, in relation to the latter, a "program" written particularly in the Java language is called a "Java program". A description has been given regarding various types of general information specified in the MPEG-2 specifications, in accordance with the present invention. Hereinafter, a hardware configuration is described prerequisite for the present modality. Fig. 13 is a block diagram showing a general hardware configuration of the transmission recording and reproducing apparatus according to the present; in other words, a specific internal configuration of the terminal apparatuses 111, 112 and 113 shown in figure 1. 1300 is the transmission recording and reproducing apparatus, 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 and a multiplexer (transport stream MPEG-2 OR similar) 1313. Note that the present modality is obtained by expanding a transmission recording and playback terminal implemented by the OCAP-DVR specifications and the basic hardware configuration it is almost identical to that required by the OCAP-DVR specifications. The tuner 1301 is a device that demodulates a transmission signal modulated and transmitted from the transmission station side system 101, according to tuning information that includes a frequency prescribed by the CPU 1306. A transport stream MPEG- 2, obtained as a result of the demodulation carried out by the tuner 1301, passes through the adapter 1311 having a descrambling function, and is sent to the TS 1302 decoder. The TS 1302 decoder is a device having a function to segregate PES packets and MPEG-2 sections that meet the specified conditions of the MPEG-2 transport stream, based on a PID, a section filter condition and so on pre-written by the CPU 1306. In case 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 case of playing a service recorded in the secondary storage unit 1307, the MPEG-2 transport stream that sends the secondary storage unit 1307 is input to the 1302 is input to the TS 1302 decoder. Which input receive is controlled by the CPU 1306. The PES packets of the video and audio segregated by the TS 1302 decoder are sent to the AV decoder 1303. In addition the MPEG-2 section segregated by the TS 1302 decoder is transferred to the primary storage unit 1308 through Direct Memory Access (DMA), and is used by a program executed by the CPU 1306. The AV 1303 decoder is a device with a function of decoding the ES of video and ES of audio encoded. The AV decoder extracts the ES from the PES packet that transmits the audio and video information sent 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 reproduction, but are sent to the AV 1312 encoder at the moment of recording the service. Which output path to take is controlled by the CPU 1306 according to an instruction coming from the user. The loudspeaker 1304 reproduces audio sent from the AV decoder 1303. The visual presenter 1305 plays video sent from the AV decoder 1303. The CPU 1306 executes a program operating in the transmission recording and reproducing apparatus. The CPU 1306 executes a program contained in the ROM 1309. Or, the CPU 1306 also executes a program downloaded from a transmitted signal or a network and contained in the primary storage unit 1308. Or, the CPU 1306 executes a program downloaded from a transmitted signal or of a network and content in the secondary storage unit 1307. The tuner 1301, decoder of TS 1302, decoder AV 1303, speaker 1304, visual presenter 1305, unit of secondary storage 1307, primary storage unit 1308, ROM 1309, input unit 1310, adapter 1311, AV encoder 1312 and multiplexer 1313 are controlled in accordance with the addresses of the executed program. In addition, the CPU 1306 is able to control the adapter 1311 by communicating not only with the devices present within the terminal apparatus 1300, but also with the devices within the adapter 1311. The secondary storage unit 1307 is a memory device, the memory which is not deleted even if the power supply to the device is interrupted. This secondary storage unit 1307 is configured of devices, for example, a non-volatile memory such as a FLASH-ROM, a hard disk drive (HDD), a rewritable medium such as a CD-R and a DVD-R, the information of which is not deleted even if the power source of the terminal apparatus 1300 is cut off. The secondary storage unit 1307 stores information according to an instruction coming from the CPU 1306. The primary storage unit 1308 is a device having a function of temporarily storing information according to an instruction coming from the CPU 1306, a device transmissible by DMA, and so on, and is configured of a RAM or the like. The input unit 1310 is a device for non-rewritable memory, and to be more specific, it is configured of a ROM, a CD-ROM, a DVD, and the like. The program running 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. Fig. 14 is an example of a case in which the input unit 1310 is configured from the front panel. A front panel 1400 has seven buttons: an upward cursor button 1401, a downward cursor button 1402, a left cursor button 1403, a right cursor button 1404, an OK 1405 button, 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 transport stream. sent in the frequency band In Band, and includes one or more descramblers. The transport stream MPEG-2 sent by the tuner 1301a is input to the adapter 1311, and the removal of cryptography is carried out in the TS packet having the PID specified by the CPU 1306. The adapter 1311 sends the transport stream MPEG-2 descrambler to the TS 1302 decoder.

In addition, the 1311 adapter performs format conversion of sent data on an OOB frequency scale. The information sent in the OOB frequency scale can be modulated by the QPSK modulation scheme. With respect to the output transmission, the scrambler QPSK 1301b demodulates the output signal sent from the transmission station side system 101, and input a bit stream generated in the adapter 1311. The adapter 1311 extracts information specified by the GPU 1306 among various information included in the bitstream, converts the information into a format that can be interpreted by a program operating on the CPU 1306, and provides this to the CPU 1306. On the other hand, with respect to the transmission of input, the CPU 1306 enters information that will be sent to the transmission station side system 101 on the adapter 1311. The adapter 1311 converts the information entered from the CPU 1306 into a format that can be interpreted by the station side system of transmission 101, and enter this to the QPSK 1301c modulator. The QPSK 1301c modulator modulates the entered information of the 1311 adapter by QPSK, and sends this to the transmission side of the transmission system 101. A CARD Cable, formerly called an Installation Point (POD), used in the United States cable system. , 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 MPEG audio format, and encodes the video signal into video in the MPEG video format. The video and audio encoded by the AV 1312 encoder are sent to the multiplexer 1313. The multiplexer 1313 is a device with a multiplexing function, with an MPEG-2 transport stream, the video and audio input of the AV 1312 encoder as well as a section MPEG-2 obtained from the primary storage unit. Fig. 15 is a flat screen television (TV) which is an example of the appearance of the transmission recording and reproducing apparatus (terminal apparatus) according to the present embodiment. 2801 It is a flat screen TV cabinet and all the components of the terminal apparatus except for the 1313 adapter are built into the cabinet. 2802 It is a visual presenter and is an equivalent of the visual presenter 1305 shown in figure 13. 2803 It is a front panel on which several buttons are placed. 2804 It is a signal input terminal and connects cable lines for sending and receiving signals to and from the side of the transmission station system. The signal input terminal is connected to the tuner 1301a, the scrambler QPSK 1301b and the modulator QPSK 1301c. 2806 It's a slot insert to insert the adapter 1311 shown in figure 13. 2811 It is a power switch. 2812 It is a visual sub-presenter such as a liquid crystal panel. An operation in which the above-described recording and reproduction apparatus described above records a service contained in a transmission wave in the secondary storage unit 1307, and an operation in which the recording and receiving apparatus is described in detail is described below. of transmissions read consecutively from the secondary storage unit 1307 and reproduce the service. First, the operation in which the service contained in the transmission wave is recorded in the secondary storage unit 1307 is described. Figure 16 shows a conceptual interpretation representing the physical connection sequence, processing details and input data format / output of each device during service recording. 1500 is a terminal apparatus, which has: the tuner 1301; to adapter 1311; a descrambler 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 figure 16 which have the same numbers as in figure 13 have the same functions and in this way their descriptions are omitted. First, the tuner 1301 conducts tuning in the transmission wave according to a tuning instruction prewritten by the CPU 1306. The tuner 1301 demodulates the modulated transmission wave and inputs the transport stream MPEG-2 into the adapter 1311. The descrambler 1501, which is inside the adapter 1311, descrambles the MPEG-2 transport stream based on conditional access information for each observer. The descrambled MPEG-2 transport stream is entered into the TS decoder. Two types of devices that process the MPEG-2 transport stream are present within the TS 1302 decoder: the PID filter 1502 and the section filter 1503. The PID filter 1502 extracts, from the input stream MPEG-2 input, a TS packet that has a PID specified by the CPU 1306 and then extracts a PES packet and an MPEG-2 section present in that payload. For example, when the transport stream MPEG-2 in Figure 6 is entered in the case where the 1306 in which the CPU 1306 has instructed PID filtering that extracts the TS packet with a PID = 100, packets 601 and 603 they are extracted, then concatenated and in this way a PES of a video 1 is reconfigured. Or, when the MPEG-2 transport stream in Figure 6 is entered in the case in which the CPU 1306 has instructed PID filtering that extracts the TS packet with a PID = 200, the packets 601 and 603 are extracted, then concatenated and in this way an MPEG-2 section of data 1 is reconfigured. The section filter 1503 extracts, from the entered MPEG-2 sections, the MPEG-2 section that conforms to a section filter condition specified by the CPU 1306 and transfers this MPEG-2 section to the storage unit by DMA 1308. For example, CPU 1306 specifies, to the 1503 section filter, 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 that the MPEG-2 section of the data 1 is reconfigured, the section filter 1503 extracts only the section with a table_id of 64 from those MPEG-2 sections, and transfers this to the primary storage unit 1308 by DMA. MPEG-2 that is input to the primary storage unit 1308 is input to the multiplexer 1313. A PES video packet and a PES audio packet extracted by the TS 1302 decoder are input to the AV 130 decoder. 3. The AV decoder decodes the PES video package in order to convert it into video, and enter the video in the AV 1312 encoder. The AV decoder also decodes the audio PES package to convert it into audio, and enters the audio into the AV 1312 encoder. The AV 1312 encoder converts the video into video MPEG and enter this in 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 MPEG audio input from the AV encoder, with the MPEG-2 section entered of the primary storage unit 1308, and thus generate an MPEG-2 transport stream. The generated MPEG-2 transport stream is recorded in the recording area 1504. The recording area 1504 is formed of all or part of the secondary storage unit 1307, or another recording area, and records the MPEG transport stream. 2 that constitutes a service. Next, an operation in which the service is consecutively read from the secondary storage unit 1307 and reproduced will be described. Figure 17 shows a conceptual interpretation representing the sequence of physical connections, processing details and input / output data format of each device during service playback. 1600 is a terminal apparatus, which has: recording area 1504; the decoder of TS 1302; the PID filter 1502; the section filter 1503; the AV 1303 decoder; the loudspeaker 1304; the visual presenter 1305; and the primary storage unit 1308. The constituent elements of figure 17 having the same numbers as in figure 13 have the same functions and thus their descriptions are omitted. In the order described in Fig. 16, the MPEG-2 transport stream recorded in the recording area 1504 is input to the TS 1302 decoder. Next, a video ESP and an audio PES having a PID specified by the CPU 1306 are extracted by the PID filter 1502 within the decoder of TS 1302. The extracted PES packet is input to the AV decoder 1303. Or, the MPEG-2 section having a PID and a table_id specified by the CPU 1306 is extracted by the PID filter 1502 and the section filter 1503 within the decoder of TS 1302. The extracted MPEG-2 section is transferred by DMA to the primary storage unit 1308. The video PES and the audio PES entered into the AV 1303 decoder they are decoded and sent as an audio signal and a video signal. After this, the audio signal and the video signal are input to the visual presenter 1305 and speaker 1304, thus reproducing the audio and video.

The MPEG-2 section entered in the primary storage unit 1308 is input to the CPU 1306. An example of a hardware configuration relating to the present invention has been described so far. Hereinafter, a key function of the present invention is described, which is the control of the recording of the service and the control of trick playback, by means of a Java program. The recording of the service in the present invention relates to recording video, audio, a Java program, synchronization information of the Java program and so on which are contained in the service, in a storage medium such as a hard disk, a Blu-disk -ray (BD), a versatile digital disk (DVD), and a secure digital memory (SD) card. The reproduction of the service refers to the execution and reproduction of the video, audio and Java program recorded in the recording medium, based on the synchronization information. It is required that a reproduction result of a recorded service is almost equivalent to a result of directly reproducing the service after receiving a transmission wave. Figure 18 is a configuration diagram of a program necessary to record and reproduce the service, and is software recorded in ROM 1309. A program 1700 is formed of an OS 1701, a EPG 1702, a Java 1703 VN, and a Java 1704 library, which are subprograms. OS 1701 is an operating system; Linux, Windows, and the like are examples. OS 1701 is configured of: a core 1701a to execute other subprograms such as EPG 1702 and Java VM 1703; and a library 1701b used by the subprograms to control the constituent elements of the terminal apparatus 1300. The core 1701a is publicly known technology and therefore its detailed description is omitted. The library 1701b provides, for example, a tuning function for controlling a tuner. The library 1701b accepts, from another subprogram, tuning information that includes a frequency, and supplies the information to the tuner 1301. The tuner 1301 performs demodulation processing based on the tuning information provided, and the MPEG transport stream can pass. -2 demodulated to the TS decoder 1302. As a result, other subprograms can control the tuner 1301 through the library 1701b. Also, library 1701b provides channel information to uniquely identify a channel. An example of the channel information is shown in Figure 19. The channel information is sent using an OOB or a frequency scale In Band, it is converted into a graph format by adapter 1311, and it is stored in a temporary memory unit accessible by the library. A column 2001 is a channel identifier, and is equivalent to, for example, an originator identifier (hereinafter, source_ID) as defined by Service Information SCTE65 Supplied Out of Band for Digital Cable Television. A 2002 column is a channel name and is equivalent to a source name (hereinafter, source_name) as defined by the same SCTE65 standard. A column 2003 is tuning information, and is information such as a frequency, a rate of transfer, a modulation scheme and the like given to the tuner 1301. A column 2004 is a program number for specifying the PMT. For example, a 2011 row is a group of service information with a channel identifier of "1", a channel name of "channel", a frequency of "150 MHz ..." for tuning information and a number of program between "101". In addition, the library 1701b can set parameters to control the hardware configuration as shown in Figure 13. The individual functions will be mentioned later. The Java VM 1703 is a Java virtual machine that analyzes sequentially and executes programs written in the Java ™ language. The programs written in the Java language are compiled in intermediate codes, called codes of bytes, which do not depend on hardware. The Java virtual machine is an interpreter that executes these byte codes. The Java VM 1703 runs the Java 1704 library that is written in the Java language. Details of the Java language and the Java VM are explained in publications such as "Java Language Specification" (ISBN 0-201-63451-1) and "Specification of Java Virtual Machines" (ISBN 0-201-63451-X). In addition, it is possible to invoke or be invoked by other subprograms not written in the Java language through a native Java interface (JNI). The details that refer to the NYI can be found in a publication called "Native Java Interface" and so on. The Java library 1704 is a library written in the Java language and is invoked by the Java program to control functions of the transmission recording and playback apparatus. However, there are situations in which a subprogram not written in the Java language, such as a 1701b library of OS 1701, is used as necessary. The Java program can use a function provided by the Java 1704 library when invoking a Java Application Programming Interface (API) contained by the Java 1704 library. A Tuner 1704c is a Java library to control the reception tuner in Band 1301a of the recording terminal and playback of transmissions. When the Java program passes tuning information to the tuner 1704c, the tuning control unit 2911 uses that information to invoke a tuning function of 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 playback of transmissions. An SF 1704e is a Java library for controlling a function of the PID filter 1502 and the filter section 1503 of the transmission recording and playback terminal. When the Java program passes filter conditions such as a PID, table_id and similar to the SF 1704e, the SF 1704e establishes, based on the past filter conditions, filtering conditions in the PID filter 1502 and the section filter 1503 using a function of the library 1701b to thereby control the PID filter 1502 and the section filter 1503, acquire an MPEG-2 section that satisfies desired filter conditions and pass the MPEG-2 section to the Java program that has established the filter conditions . A DSM-CC 1704d is a Java library to access a file system of a DSM-CC object carousel. The DSM-CC object carousel is included in the MPEG-2 section acquired by the SF 1704e. The DSM-CC is defined by ISO / IEC13818-6, and is a mechanism for sending an arbitrary file, using the MPEG-2 section. By using this system, it is possible to send a file from a station transmission to a terminal. The DSM-CC 1704d obtains the MPEG-2 section using the SF 1704e, based on a file identifier specified by a Java program or similar, it outputs a file based on ISO / IEC13818-6 standards, and sends the file. A detailed method for implementing the DSM-CC is not related to the present invention and therefore its details are omitted. An AM 1704b is an application manager that provides a function to manage the execution and termination of the Java programs contained in the service. The AM 1704b extracts a Java program multiplexed on a channel specified by a specified MPEG-2 transport stream, and causes the execution or termination of that Java program extracted according to synchronization information multiplexed separately. A Java class file of the Java program is multiplexed into the transport stream MPEG-2 based on the DSM-CC method mentioned above. In addition, the synchronization information of the Java program is multiplexed into the transport stream MPEG-2 in a format called AIT. AIT is an acronym for application information table, as defined in chapter 10 of the DVB-MHP specification (ETSITS 101812 DVB-MHP specification Vl .0.2), and is an MPEG-2 section with a table_id of "0x74" . In the present embodiment, the AIT defined by the DVB-MHP specification is modified to be used.

Figure 20 shows an internal structure of the AM 1704b. The AM 1704b is configured of an AIT 3502 monitoring unit and an application status management unit 3503. The AIT 3502 monitoring unit has an MPEG-2 transport stream and a channel identifier as inputs, and monitors the status update of the AIT. First, the AM 1704b searches for channel information in the library 1701b, which has a channel identifier specified as a key, and obtains the program number. Next, using the SF 1704e and the like, the PAT is acquired from the MPEG-2 transport stream. Then, the PID of a PMT that corresponds to the program number obtained is acquired from the information of the PMT. Using the SF 1704e again, the actual PMT is acquired. The acquired PMT is in the format shown in Figure 11, and the PIDs of elementary streams that have "data" as a type of stream and "AIT" as supplementary information are written there. When the SF 1704e is provided with the PID of the obtained AIT and table_id "0x74" as the filtering conditions, the details of the AIT can be obtained. Figure 21 is a graph schematically showing an example of the information in the AIT. A version of AIT 2200 expresses the version of that AIT. The higher the version of the AIT, the more recent the AIT will be. The AIT with the same version of AIT is received repeatedly, but AM 1704b does not analyze AIT with the same version of AIT since an AIT has already been analyzed, and only analyzes an AIT that is more recent than the AIT already analyzed. A column 2201 is an identifier of the Java program. A column 2202 is control information of the Java program. In the control information, there is "autostart", "present", "delete" and the like; "auto start" means that the terminal apparatus 1300 executes the Java program automatically in an instant, "present" means that no automatic execution is carried out, and "delete" means stopping the Java program. A column 2203 is a DSM-CC identifier for extracting the PID that includes the Java program, based on the DSM-CC method. A column 2204 is a program name of the Java program. A column 2205 is an indicator that complies with trick playback, and in the case of a service that includes a Java program that is played in a trick play mode, it indicates whether or not the Java program is executed. When an indicator that meets trick playback indicates "true", the Java program plays even if the service that includes the Java program is being played in a trick play mode. Conversely, when an indicator that meets trick playback indicates "false", the Java program does not run while the service is playing in trick play mode, and it runs only during the operation of normal reproduction of the service. For example, in case there is a possibility of affecting the whole system due to the failure of the Java program included in the service, after operating fast forward and jumping during service playback, it is possible to prohibit the execution of the Java program during the Playback of the service in trick play mode by specifying the indicator that matches trick play as "false". The rows 2211, 2212, 2213 and 2214 are groups of the Java program information. The Java program defined in row 2211 is a combination of a Java program identifier "301", "autostart" control information, a DSMCC identifier "1" and a program name "a / TopXlet". Similarly, the Java program defined in row 2212 is a combination of a Java program identifier "302", "present" control information, a DSMCC identifier "1" and a program name "a / GameXlet". Here, the three Java programs defined by rows 221, 2212 and 2214 have the same DSMCC identifier. This indicates that three Java programs are included in a file system encoded based on the DSM-CC method. Here, four types of information are pre-written for the Java program, but in reality, more types of information are defined. Details can be found in the DVB-MHP specification. The application status management unit 3503 analyzes the details of the updated AIT, and manages the execution status of a Java program based on the details of the AIT as well as notification of the start and end of the playback in trick play mode from the service manager 1704f which will be mentioned later. The operation of managing the state of a Java program is described below. The application state management unit 3503 finds a Java program that has the "auto-start" control information of the AIT, and extracts the corresponding DSMCC identifier and Java program name. Referring to Figure 21 AM 1704b extracts the Java program from row 2211, and obtains a DSMCC identifier of "1" and a Java program name "a / TopXlet". AM 1704b then obtains, from the PMT, a PID of the TS packets in which the Java program is stored in DSMCC format. To be more specific, AM 1704b obtains the PID of the elementary current that has, within the PMT, "data" as a type of current and a DSMCC identifier that corresponds to the DSMCC identifier of the complementary information. Here, assuming that the DSMCC identifier is "1", and the PMT is as shown in Figure 11, the elementary stream of row 1114 is equalized and the PID "5014" is removed. The AM 1704b specifies the PID and the conditions of section filter of the TS packets to send the MPEG-2 section in which the data is inserted based on the DSMCC method. Here, the PID "5014" is provided. As a result, the AM 1704b can collect necessary DSMCC MPEG-2 sections. The AM 1704b reconstructs the file system from the MPEG-2 sections collected according to the DSMCC method, and stores the reconstructed file system in the primary storage unit 1308. The invocation of data such as the file system of the TS packets in the MPEG-2 transport stream and the saving of the data in a storage medium such as the primary storage unit 1308 and the secondary storage unit 1307 is hereinafter called download. Figure 22 is an example of a downloaded file system. In the diagram, a circle represents a directory and a square represents a file. 2301 is a root directory, 2302 is a "a" directory, 2303 is a "b" directory, 2304 is a "TopXlet. Class" file and 2305 is a "GameXlet. Class" file, 2306 is a "z" directory , 2307 is a "MusicXlet. Class" file and 2308 is a "StudyXlet. Class" file. 2309 is a bitmap file of "TopXlet.bmp" icons. Subsequently, the AM 1704b passes to the Java VM 1703, a Java program that will be executed from the file system downloaded to the primary storage unit 1308. Here, assuming that the Java program name that will be executed is "a / TopXlet", a file "a / TopXlet. class", which results from the ".class" appendix to the name of Previous Java program, is a file that will be executed. "/" is a division between directory and file names, and file 2304 is the Java program that must be executed with reference to figure 22. Then, after AM 1704b passes file 2304 to the Java VM 1703, the file is executed as a Java program in the Java VM. Each time an AIT with the new version of AIT is entered, the AM 1704b analyzes the AIT and changes the execution status of the Java program. Here, in case "delete" is specified for the control information, the AM 1704b terminates the Java program, and also, notifies the 2702 trick playback instruction program judgment unit of the program's Java program identifier Java finished. So far, the operation and management of the Java program state carried out by the application state management unit has been described. When the start of playback in the trick play mode is reported from the service manager 1704f, the application state management unit 3503 subsequently carries out the Java program status management operation described above. only for the Java program that has an indicator that matches trick playback of "true". The application state management unit 3503 then removes the Java program that has an indicator that matches trick playback from "false" and does not execute that Java program even if the control information is "auto-start". The application state management unit 3503 further notifies a Java 3103 program suspension processing unit that will be mentioned below, the following: a Java program identifier of the Java program that has just been removed; a Java program identifier of the Java program that has not been activated, that is, the Java program that has the flag that complies with "false" trick playback and the "autostart" control information; the Java program names of these Java programs; one hour of update (that is, one hour when the initial AIT describing the "auto-start" control information for each of the Java programs is updated) of the AIT that describes these Java programs, - and bitmap files of icons of these Java programs. The notification is carried out in case a Java program is eliminated and every time the AIT is updated. The update time of the AIT is presented not by a real time but by an hour of media of the MPEG-2 transport stream in which the stream header MPEG-2 transport stored in the secondary storage unit 1307 is defined as being "0". The media time is a unique time stamp for the media. In the period of time during which playback is performed in the trick play mode, the media time may advance or delay with the speed corresponding to the playback in the trick play mode. This time can be calculated based on the size of the total file reading and a bit rate of the MPEG-2 transport stream. For example, the media time at the time of reading 8 MB of the recorded file at the speed of 3 Mbps is 00:00:03. On the other hand, when the end of the playback in the trick play is notified from the service manager 1704f, the application state management unit 3503 subsequently carries out the Java program state management operation as described above for all Java programs notwithstanding an indicator value that fulfills trick playback. Note that in the initial state, the service is played in a normal playback mode; therefore, the operation is carried out under the assumption that the end of the trick play in the trick play mode has been notified. A JMF 1704a handles the control of the reproduction of the video and audio contained in the service. To be more specific, the JMF 1704a enters the ES video and IS audio multiplexed in the channel specified by the MPEG-2 transport stream specified in the AV decoder, so the AV decoder reproduces them. In the case of reproducing the service directly from the received transmission wave, it is specified that the transport stream MPEG-2 sent from the adapter 1311 must be reproduced by the loudspeaker 1304 and the visual presenter 1305. In case of reproducing the service that is recorded once in the secondary storage unit 1307, it is specified that the transport stream MPEG-2 sent from the recording area 1504 within the secondary storage unit 1307 must be reproduced by the loudspeaker 1304 and the visual presenter 1305. First , JMF 1704a searches for channel information in library 1701b with a channel identifier specified as a key, and obtains the program number. Then, using the SF 1704e and the like, the PAT of the MPEG-2 transport stream is acquired. Then, the PID of a PMT that corresponds to the program number obtained is obtained from information from the PMT. Again, using the SF 1704e, the actual PMT is acquired. The acquired PMT is in the format shown in Figure 11, and the PIDs of elementary streams that have "video" and "audio" as the current types are written on it. When the JMF 1704a establishes those PIDs in the PID filter 1502 of the TS 1302 decoder through the library 1701b, the video ES and the audio IS, in the which those PIDs are multiplexed, are reproduced by means of the AV 1303 decoder as well as the loudspeaker 1304 and the visual presenter 1305, as shown in figure 16 or figure 17. In the particular case in which the JMF 1704a enters the transport stream MPEG-2 that is already recorded in the secondary storage unit, the JMF 1704a can change the playback speed of the video and audio by changing the speed and position of the MPEG-2 transport stream reading. Thus, it is possible to perform trick playback such as fast forward and jump. For example, in case the MPEG-2 transport stream is read at a speed that is twice the normal speed, the video and audio are also recorded at a speed that is double the normal speed. In case the reading position of the MPEG-2 transport stream is read after a predetermined interval is skipped, the video and audio will be played back with this jump. The JMF 1704a controls the secondary storage unit 1307 using the functions of the library 1701b, and changes the reading position and speed of the MPEG-2 transport stream. The method of performing this trick play at a high level deviates from the scope of the present invention, therefore, its descriptions are omitted. For the Java program to instruct on trick playback, the JMF 1704a provides the Java program with, for example, an API called setRate (float factor). The parameter "factor" has a service reproduction speed, and when the "factor" parameter is specified as 1.0, the reproduction is carried out at normal speed, whereas when the "factor" parameter is specified as 2.0, the Playback in trick play mode will be performed with speed twice as fast as normal speed. When setRate () is invoked, a value of the "factor" service playback speed is reported to a trick playback detection unit 3102 that will be mentioned later. In addition, the JMF 1704a also provides the Java program with an API called "setPosition (int time)" to change the position to start playback. An "hour" parameter indicates the playback start position specified by the media time starting from the header of the MPEG-2 transport stream. When "setPosition ()" is invoked, the JMF calculates the data size up to the specified time based on the bit rate of the MPEG-2 transport stream, reads from the secondary storage unit 1307, the transport stream MPEG-2 starting from the position in which the jump mode is operated with the size calculated as deviation. Thus, the service is reproduced after the specified time. By having the channel identifier, start time and At the end time entered as inputs, the recording manager 1704h records the service in the secondary storage unit 1307, only during the time period between the start time and the end time that are specified. For example, when the channel identifier, start time and end time are specified by EPG 1702, the recording manager 1704h waits until the start time is reached. Then, when the start time is reached, the recording manager 1704h starts recording the specified service, and when the end time is reached, the recording manager 1704h ends the recording. The details will be described below. When the recording start time is reached, the recording manager 1704h first reserves, within the secondary storage unit 1307, a recording area 1504 to record the MPEG-2 transport stream from the specified start time to the end time specified. A media identifier is supplied to the reserved recording area. Then, with the channel identifier as a key, the recording manager 1704h obtains tuning information corresponding to the channel identifier, of the channel information contained by the library 1701b. After that, when the tuning information is supplied to the tuner 1704c, the tuner 1704c begins to tune. Here, the Tuning information is information that can specify a frequency, a method of modulation and the like. Then, as shown in Figure 16, the transport stream MPEG-2 is input to the TS decoder via adapter 1311. Then, using the SF 1704e, the recording administrator 1704h acquires the PAT of the transport stream MPEG-2 obtained through tuning. In addition, the recording manager 1704h searches for the program number corresponding to the channel identifier specified in the library 1701b, and searches for the PID of the corresponding PMT in the PAT. After that, using the SF 1704e, the recording manager 1704h acquires an actual PMT, and obtains all the PIDs from the ESs that constitute the specified channel. The recording manager 1704h establishes the PIDs obtained in the PID filter 1502 of the TS decoder. Moreover, an output destination of each hardware constituent element is established through the library 1701b to follow the recording operation of the service included in the transmission wave in the secondary storage unit 1307. Then, according to the The flow described in Figure 16, all the ESs that constitute a desired channel are recorded in the reserved recording area 1504. 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 transport stream MPEG-2 in the recording area 1504 to come to an end. In addition, a recording information management table such as that shown in FIG. 23 is created as management information of the MPEG-2 transport stream recorded above. Figure 23 is an example of the recording information management table for managing recording information recorded in the recording area 1504 of the secondary storage unit 1307 or the like. The recording information is recorded in graphic format. A column 2101 has a recording identifier. A column 2102 describes channel identifiers. A column 2103 indicates a program number. A column 2104 is the recording start time for the service, and a column 2105 is the recording end time for the service. A column 2106 is a media identifier that identifies the MPEG-2 transport stream that is recorded as the service. Each of the rows 2111 and 2112 is a group consisting of a recording identifier, a channel information, a program number, a start time, an end time and a media identifier. For example, row 2111 shows a recording ID of "000", a channel information of "2", a program number of "102", a start time of "2005/03/30 11:00", one hour to end "2005/03/30 12:00", and a media identifier of "TS_001". A service manager 1704f manages the reproduction of the service within the transport stream MPEG-2 that has been recorded in the secondary storage unit 1307, or the service within the transport stream MPEG-2 entered from the adapter 1311. The figure 20 shows a detailed internal structure of the service manager 1704f. The service manager 1704f is configured of a service reproduction unit 3101, a trick playback detection unit 3102, a Java program suspension processing unit 3103, and a Java program 3104 suspension display unit. AM 170b and JMF 1704a are shown in the diagram, however, they have the same constituent elements as the constituent elements with the same reference numbers shown in Figure 18, therefore, their descriptions are omitted. The service reproduction unit 3101 reproduces a service. Hereinafter, an operation is described in the case of managing the reproduction of the service contained in the MPEG-2 transport stream that has already been recorded in the secondary storage unit 1307. This is equivalent to the reproduction of an already recorded service. In this case, the service manager 1704f has the recording identifier as an entry. The service that it is already recorded in the secondary storage unit 1307 and is specified by that recording identifier to be reproduced. First, with reference to the recording information management table created by the recording manager 1704h, the service reproduction unit 3101 obtains the channel identifier and media identifier of the channel to be reproduced, with the identifier of specified recording. Then, through the library 1701b, the service manager 1704f instructs the secondary storage unit 1307 to send, to the TS 1302 decoder, the transport stream MPEG-2 specified by the obtained media identifier. In addition, through the library 1701b, the service manager 1704f sends the output destination of each hardware constituent element to flow through the path shown in FIG. 17. After this, the secondary storage unit 1307 is provided. to JMF 1704a as the location of the transport stream MPEG-2, and the channel identifier of the channel 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 transport stream sent from the secondary storage unit 1307. After that, the secondary storage unit 1307 is provided. to JMF 1704a as the location of the transport stream MPEG-2, and the channel identifier of the channel to be reproduced is provided. Then, according to the multiplexed AIT in the transport stream MPEG-2 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 unit of secondary storage 1307. After that, the reproduction of the service continues until the end of the transport stream MPEG-2 sent from the secondary storage unit 1307. On the other hand, the case of managing reproduction of the service within the transport stream MPEG-2 entered from adapter 1311 is described below. This is equivalent to the reproduction of the service directly from the transmission wave. In this case, the service reproduction unit 3101 within the service manager 1704f has the channel identifier of the service that will be reproduced as the entry. Through the library 1701b, the service reproduction unit 3101 instructs the transport stream MPEG-2 sent from the adapter 1311 shown in figure 16 which is sent to the decoder of TS 1302. In addition, through the library 1701b , the service administrator 1704f establishes the exit destination of each hardware constituent element to flow through the path shown in Figure 17. After that, the adapter 1311 is provided to the JMF 1704a as the location of the transport stream MPEG-2, and the channel identifier of the channel that will be reproduced is provided. Then, through the operation described above, the JMF 1704a begins playback of the video and audio multiplexed in the transport stream MPEG-2 sent from the adapter 1311. In addition, the adapter 1311 is provided to the AM 1704b as the location of the MPEG-2 transport stream, and the channel identifier of the channel that will be reproduced is provided. Then, according to the multiplexed AIT in the transport stream MPEG-2 sent from the adapter 1311, the AM 1704b starts the execution and termination of the multiplexed Java program in the transport stream MPEG-2 sent from the secondary storage unit 1307 After this, the playback of the service continues until the end of the MPEG-2 transport stream sent from the secondary storage unit 1307. The trick playback detection unit 3102 determines the start and end of the playback operation of the device. trick with respect to the service that is currently being reproduced, based on the value of the service reproduction speed "factor" entered from JMF 1704a, and notifies the AM 1704b of the start and end of the reproduction in the trick play mode. When the factor = 1.0, it is judged that the reproduction is carried out in a normal reproduction mode. During the normal playback operation, when a value other than 1.0 is recently entered as a "factor" by the JMF, the trick play detection unit 3102 judges that the playback in the trick play mode was initiated, and notifies to the application status management unit 3202 within the AM 1704b of "start trick play operation". During playback in the trick play mode, when the factor = l .0 is recently entered from the JMF, the trick play detection unit 3102 judges that the trick play is terminated, and notifies the administration unit of application status 3202 within the AM 1704b of "conclude trick play operation". The Java 3103 program suspension processing unit operates based on an input from the AM 1704b. From AM 1704b, a Java program identifier of a Java program that is finished or not executed, a Java program name of that Java program, an AIT update time in which that Java program is described and a map file of bits of that Java program are entered. In the case of this entry, the Java 3103 program suspension processing unit enters the above information into a visual presentation unit of suspension of Java 3104 programs that will be mentioned later. Also, the information mentioned above is also entered into a privilege handler invoking unit 3105. The visual display unit of Java program 3104 visually presents a dialogue on the screen of the visual presenter 1305 based on the input of the information mentioned above from the Java 3103 program suspension processing unit. Figure 24 is an example of the dialog. A dialogue 2901 is presented visually on the visual presenter 1305. In the dialogue 2901, a Java program that has had its execution suspended is visually presented. In the example shown in Fig. 24, a Java program name 2902, a Java program identifier 2903, a Java program icon 2904, a "perform jump to start and return to normal playback" button 2905 are displayed visually, and a button "cancel" 2906. The button "carry out jump to start and return to normal playback" 2905 and the button "cancel" 2906 can be selected by means of a remote control. When the user presses the "perform jump to start and return to normal playback" button 2905, the visual display unit of Java 3104 program suspension causes the dialog to disappear. After this, "setPosition (int time)" a JMF 1704a API is invoked when specifying the update time of the AIT that includes that Java program at "hour". Then, when invoking "setRate (1.0)", the service playback speed is returned to normal speed. Thus, the reproduction of the service is restarted from the position where the AIT of the Java program that has had its execution suspended appears, and the reproduction of the service in the trick play mode is terminated to return to the normal playback mode. In this way, the service will be reproduced in the state where the Java program that has not been executed for a long time is executed. In case the button "cancel" 2906 is pressed by the user, nothing happens, but the dialogue disappears. Here, the Java 3104 program suspend presentation unit should update the details of the dialog each time that Java program information of the Java program that has had its execution suspended is entered from the Java 3103 program suspension processing unit. other words, in case the new updated AIT does not include at all the Java program information of the program that has had its execution suspended so far, the dialogue presented visually will disappear. The privileged driver manager 1704g is configured with a 3105 privilege handler invocation unit and a handler register unit privileged 3106. The privileged handler registration unit 3106 provides the Java program with a Java API called "registerHandler (Handler h)". When the Java program implements an arbitrary program code as a Handler class and specifies the program to a parameter h in order to invoke the API, the privileged handler register unit 3106 passes that handler to the privilege handler invocation unit 3105. The privilege handler invocation unit 3105 stores the handler h passed from the privileged handler registration unit 3106 to the primary storage unit 1308. After that, when the information referring to the Java program that has had its execution suspended is input from the processing unit of Java 3103 program suspension, the 3105 privilege handler invocation unit invokes the handler h that has just been registered, in order to execute the program code described in the handler. Handler h is here a Java class that has a callback method called "notifydnfo i)". "Info" is a kind of data contention that may contain the Java program identifier of the Java program that has been terminated or not been executed, the Java program names of these Java programs, the AIT update time that describes these Java programs and the icon bitmap files of these Java programs. By the fact that the privilege handler invocation unit 3105 invokes the return method, the program code described in the handler h can freely execute the operation based on the information that refers to the Java program that had its execution suspended. For example, the handler h may have a program code to visually present the dialogue as described in the description of the Java program suspension display unit 3104. When the "setRateO" and "setPosition ()" methods are provided. of the JMF 1704a as Java APIs, it is possible for the h handler to invoke these methods. The EPG 1702 is an Electric Program Guide, and is a function that allows a user to select a TV program that will be recorded and played. The normal reproduction operation after receiving a transmission wave deviates from the scope of the present invention and thus its descriptions are omitted. In case of recording a TV program, the EPG 1702 visually presents a list of broadcast TV programs, and allows the user to select a desired TV program. Figure 25 is an example of a visual screen presenter to allow the user to select a TV program that will be recorded. One hour 1901 and 1902 channels and 1903 are presented visually in a grid, and it is possible to review the TV programs of each channel that are recordable in each hour. It is possible for the user to move a focus 1911 within the screen using up, down, right and left cursor buttons 1401 to 1404 which are included in the input unit 1310 of the terminal apparatus 1300. Furthermore, when an OK button is pressed 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 to 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 that information, the recording manager 1704h records the TV program in the secondary storage unit 1307. On the other hand, in case of playing a recorded TV program, the EPG 1702 visually presents a list of the programs of TV already recorded, and allows the user to select a desired TV program. Figure 26 is an example of a visual screen presenter to cause the selection of an already recorded TV program. All TV programs stored in the secondary storage unit 1307 at that time point are listed. It is possible for the user to move a focus 1801 within the screen when using the up and down cursor buttons 1401 and 1402, which are included in the input unit 1310 of the terminal apparatus 1300. Moreover, when the OK button 1405 is pressed, the TV program that is currently highlighted is selected. to be reproduced. 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 reproduction service unit 1301 within the service manager 1704f of the identifier recording of that TV show. Based on that information, the service manager 1704f reads the TV program from the secondary storage unit 1307 and plays it. The operating characteristics of the transmission recording and reproducing apparatus having the configuration described above in the present embodiment will be described below with reference to a flow diagram. Figure 27 is a flow diagram showing an example of the operation used in recording a service. When the user selects a service that will be recorded, using EPG, the EPG enters, in S3201, a channel identifier, a start time and an end time in the recording manager. Then, the recording manager waits until the start time is reached. When the start time is reached, the process goes to S3202 and the recording manager secures a recording area in the secondary storage unit, gives tuning information to a tuner and also adjusts the input and output of each hardware constituent element in such a way that the signal flows as shown in figure 16 Then, moving to S3203, video, audio and section data of the service selected by the EPG are multiplexed and recorded as an MPEG-2 transport stream in the secondary storage unit. After that, when the end time is reached, the recording manager stops the tuner tuning operation and stops recording on the secondary storage unit. The recording manager also creates a recording information management table. With the operation as described above, the service selected by the EPG is recorded in the secondary storage unit. Next, the case of reproducing the service recorded in the secondary storage unit will be described. Figures 28, 29 and 30 are flow diagrams showing an example of the operation of reproducing the recorded service using MPEG-2 transport stream format in the secondary storage unit. First, when the recorded service to be reproduced is selected, EPG 1702 enters, in S3001 in FIG. 28, a recording identifier in the recording unit.

Service Replication 3101 from Service Manager 1704f. Then, moving to S3002, the service reproduction unit 3101 of the service manager 1704f searches for the channel identifier and the media identifier corresponding to the recording identifier. After that, in S3003, the service reproduction unit 3101 of the service manager 1704f establishes the input and output of each constituent element, and controls in such a way that the MPEG-2 transport stream is sent from the storage unit secondary to the TS decoder and the signal flows as shown in figure 17. Further, in S3004, the service reproduction unit 3101 of the service manager 1704f gives the channel identifier to the JMF 1704a. Then, the process goes to S3005, and the JMF 1704a plays the video and audio specified by the specified channel identifier. On the other hand, in S3006, the service reproduction unit 3101 of the service manager 1704f specifies, for the AM 1704b, the secondary storage unit as the location of the MPEG-2 transport stream, and notifies the channel identifier of the channel that will be reproduced. Thereafter, a process used by the AM 1704b to start and stop a Java program is executed. Fig. 29 is a flow diagram showing the operation. First, in S3301, AM 1704b verifies the notification detail that specifies the playback speed through the invocation of "setRateO" carried out by the JMF 1704a to the trick play management manager. First, in S3302, the playback speed has been 1.0 so far and AM 1704b judges whether the speed is changed or not by a value other than 1.0 when invoking "setRateO". In case the speed changes, the process changes to S3303, and the AM 1704b is notified of the beginning of playback in the trick play mode. Then, in S3304, the AM 1704b removes all Java programs with indicator that matches trick playback = false, among the Java programs that are being executed. In S3305, AM 1704b verifies if the AIT is updated or not and the details updated. Moving to S3306, the AM 1704b activates and terminates only the Java programs with indicator that meets "trick playback = true", based on the control information in the updated AIT. Then, moving to S3307, the AM 1704b notifies the Java 3103 program suspension processing unit of the Java program identifiers of the deleted Java programs and the Java programs with "indicator that matches trick playback = false". S3309 is an operation carried out by the Java program suspension processing unit 3103 and will be described with reference to FIG. 30. In S3401, the processing unit of suspension of Java programs 3103 notifies the visual presentation unit of Java program suspension 3104 of the Java program information. Turning to S3402, the Java 3104 program display presentation unit visually presents, in a dialog, the deleted Java programs and the Java programs that have not been executed. Here, the AM 1704b judges, in S3403, if the button "carry out jump to start and normal playback" is pressed or not, and in case the button is pressed, the process goes to S3404. In S3403, with the "setPosition" (update time of the AIT that includes the Java program), the playback is restarted from the time of update of AIT until when the time is tracked again, and with "setRate (1.0 ) ", the reproduction is carried out at normal speed. In this way, the services are reproduced again at normal speed after returning to the time at which the AIT is updated, therefore, the service is reproduced again in the state in which the deleted Java programs and the Java programs with "indicator that meets trick playback = false" are activated. Thus, the operation carried out by the Java program suspension display unit 3104 concludes, the process passes to S3404 and the operation carried out by the privilege handler invoking unit 3105 continues. That is, the suspension processing unit of Java 3103 programs notifies the privilege handler invoking unit 3105 of the Java program information. Then, at S3405, the privilege handler invoking unit 3105 performs redial execution on the handler h that has been registered in the privileged handler register unit 3106 in the past. In this way, an arbitrary Java program described in handler h is executed. Here, returning to Figure 29, when "setRateO" of the JMF is invoked in S3310, the process restarts from S3301. Note that in case the playback speed does not change from 1.0 to a value other than 1.0 in S3302, the process goes to S331. In S3311, it is judged, on the contrary, if the speed indicated by a value other than 1.0 is changed or not changed back to 1.0, and in case the speed is changed, the process goes to S3312 and the AM 1704b is notified of the end of the reproduction the trick play mode. After that, the updated details of the AIT are verified in S3313, and the activation and termination of the Java program is controlled, in S3314, based on the control information regardless of the value of the indicator that fulfills trick playback. Then, in S3315, when "setRateO" of the JMF is invoked, the process restarts from S3301. Thus, through the operation described above, in case the AIT (l) as shown in Figure 31, by For example, the activation and termination of the Java program is carried out based on all the control information, regardless of whether the service is being played in a trick play mode or in a normal play mode. In another example of receiving the AIT (2) as the AIT that is updated during the normal playback operation, only the Java program (Java program identifier = 301) of the row 2721 is activated. After this, when the playback in trick play mode is started by invoking "setRateO" with the value that is not the 1.0 factor, the Java program (Java program identifier = 301) of row 2721 is removed. When the AIT (2) is received during playback in trick play mode, the Java program is not executed. Thus, according to the present modality, in case the Java program is terminated due to the beginning of the reproduction of the service in the trick play mode, the use is informed of the state so the user can know the presence of the Java program that should run normally and apply the method of returning the trick play mode back to the normal playback mode. In this way, it is possible to prevent the Java program from being executed.

Second Mode Figure 32 is a block diagram showing a general hardware configuration of the transmission recording and reproducing apparatus according to the present embodiment; in other words, a specific internal configuration of the terminal apparatuses 111, 112 and 113 shown in figure 1. 1300 is the transmission recording and reproducing apparatus, 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 and a multiplexer (transport stream multiplexer MPEG-2 or the like) 1313, a section conversion unit 2401 and a section reading unit 2501. The constituent elements separate from the multiplexer 1313, the conversion unit of section 2401 and section reading unit 2501 are the same as the constituent elements with the same reference numbers shown in figure 13, therefore, their descriptions are omitted. Multiplexer 1313 differs from that described in the first embodiment in that the former does not multiplex AIT sections and DSMCC sections. Apart from that, they are the same.

The section conversion unit 2401 records the section that has not been multiplexed by a multiplexer in the recording area 1504 of the secondary storage unit 1307. The AIT sections and the DSMCC sections that have been filtered by the TS 1302 decoder are recorded in the recording area 1504 through the section conversion unit 2401 without passing through the multiplexer after passing through the primary storage unit 1308. The recording of the section in the recording area 1504 differs depending on the section format. In case of a file system recorded in an MPEG-2 transport stream in a DSMCC file system, the file system is converted into a single file system format for the recording area 1504, which is in turn only for a terminal, and records the file system in the recording area 1504. In addition, with respect to an AIT, the section conversion unit 2401 converts the AIT to a format of an expanded recording information management table, as in FIG. 33, and records the AIT in the recording area 1504. The recording information management table shown in FIG. 33 is an expanded version of the recording information management table shown in FIG. 23; the items identified with the The same reference numbers in both tables have the same meaning as those in the recording information management table shown in Figure 23. Their descriptions are therefore omitted. Each of the rows 2611 and 2612 shows recording information of a service. Each of the rows 2611, 2612 has a recording identifier 2101, a channel identifier 2102, a program number 2103, a service start recording time 2104, a service recording end time 2105, a service identifier means 2106 and a reference to an AIT information management table. The AIT information management table has a media time of 2621 and a version of AIT 2622 that corresponds to it. The media time 2621 is the time at the time of playback of the corresponding MPEG-2 transport stream, and shows a position in the corresponding MPEG-2 transport stream. The AIT version number 2622 corresponds to a version number of AIT 2200 in Figure 21. For example, recording information of the service having "001" as a recording identifier 2101 has "TS_002" as a media identifier. 2106, and when the media time 2621 indicates "00:00:00" in the referred AIT information management table, the corresponding AIT 2622 version number is "1". In the same way, when the media time 2621 indicates "00:05:00", the The corresponding AIT 2622 version number is "2" and when the media time 2621 hits "00:20:00", the corresponding AIT 2622 version number is "3". For example, at the time of playback of the service having "001" as a channel identifier 2601, referring to the recording information management table, the MPEG-2 transport stream that is multiplexed with the video and audio specified by the media identifier 2602 of "TS_002" is reproduced; in addition, referring to the AIT information management table, when the media time 2621 reaches "00:00:00", control that causes the Java program to start or finish is carried out according to the AIT with a AIT 2622 version number of "1". Similarly, the control that causes the Java program to start or end is carried out according to the AIT with a version number of AIT 2622 of "2" when the media time 2621 reaches "00:05:00", and according to the AIT with a version number of AIT 2622 of" 3"when the media time 2621 reaches" 00:20:00". The real AIT is converted, as a binary file in private section format, into the single file system format for the recording area 1504, which is in turn unique to a terminal, and is recorded in the recording area 1504. The recorded file is given a unique file name by which it can be uniquely identified, and the which is recorded in the recording information management table as an AIT file name 2623. In a real transmission wave, the AITs with the same version of AIT are transmitted repeatedly any number of times, but in the present modality, the detect a change in the received AIT version, only the first AIT that is updated at that time point is recorded in the recording area 1504. The section reading unit 2501 searches for the media time that corresponds to the playback time current of the MPEG-2 transport stream that is read from the recording area, reads the AIT and the DSMCC file that correspond to the middle time of the file, and passes them to the AIT monitoring unit. In other words, the AIT 3201 monitoring unit does not refer to the filtering result of the TS decoder as shown in the first embodiment, but instead obtains the AIT binary file and the DSMCC file system of the section reading unit. 2501. The operation used by the recording and reproducing apparatus of transmissions as described above in the recording of the service contained in a transmission wave in the secondary storage unit 1307 and the reproduction of the service by sequentially reading are described in detail below. the service of the secondary storage unit 1307.

First, the operation of recording the service included in a transmission wave is described below. Figure 34 shows a conceptual interpretation representing the sequence of physical connections, processing details and input / output data format of each device during service recording. The constituent elements in the diagram which have identical numbers to the constituent elements shown in figure 16 have already been described in the first embodiment, and therefore, the descriptions are omitted. The hardware configuration shown in Figure 34 differs from that in Figure 16 in that the AIT section and the DSMCC sections that have been filtered by the TS decoder 1302 are recorded in the recording area 1504 by means of the conversion unit. section 2401 without going through the multiplexer after passing through the primary storage unit 1308. Next, the operation of reproducing the service by reading the service of the transport stream MPEG-2 recorded in the unit will be described. secondary storage 1307. Figure 35 shows a conceptual interpretation representing the sequence of physical connections, processing details and input / output data format of each device during service playback. The constituent elements in the diagram that have numbers identical to the constituent elements shown in figure 17 have already been described in the first embodiment, and therefore, their descriptions are omitted. The hardware configuration shown in Figure 35 differs from that in Figure 17 in that the section stored in the recording area 1504 is read in the primary storage by means of the section reading unit 2501 without passing through the decoder of TS. An example of a hardware configuration that relates to the present invention has been described so far. Hereinafter, a key function of the present invention is described, which is the control of the recording of the service and the control of the trick reproduction by means of a Java program. The structure of the program necessary for the recording and reproduction of the service is the same as that shown in figures 18 and 20 used in the first mode, and is stored in software in ROM 1309. The constituent elements other than the AM 1704b shown in the diagram they have the same function as those described in the first modality and therefore their descriptions are omitted. The AM 1704b has the internal structure as shown in Figure 20, as in the first mode. The AIT 3201 monitoring unit differs in that it reads the AIT file recorded separately in the secondary storage unit, instead of obtaining, through filtering, the multiplexed AIT with the MPEG-2 transport stream that is read from the secondary storage unit 1307. The monitoring unit AIT 3201 checks the AIT of the current media time with the media time 2621 within the AIT information management table, obtains the AIT file name that corresponds to the current media time, and reads an AIT file real. As the media time and the time to refer to another AIT are reached, the AIT 3201 monitoring unit reads a new AIT. In other words, this is equivalent to updating the AIT version. Therefore, the valid AIT time of the current version must come from a valid start time of the AIT until the valid start time of another AIT. The application status management unit 3202 reads the Java class file that is recorded in an original file system format in the secondary storage unit 1307, instead of reading the input reading of the Java program from the section DSMCC multiplexed with the transport stream MPEG-2. The AP operation other than that is the same as that of the application status management unit according to the first mode.

Here, the case of reproducing, from the recording area 1504 at normal speed, the service corresponding to the channel identifier "001 !, using the AIT shown in FIG. 21 and the recording information management table is taken as an example. shown in figure 33. When the service corresponding to the channel identifier "001" is specified as a service that will be reproduced, each one of the audio, video and Java programs that belong to and the service are reproduced and activated, as already mentioned in the description that refers to the reproduction of the service, in case one hour of means to start the reproduction is not specified, the reproduction starts from the time of means 2621 of "00:00:00". words, such as audio and video, the transport stream MPEG-2, which has a media identifier 2102 of "TS_002" which corresponds to a recording identifier 2101 of "00:00:00", is reproduced from the time of m Edios 2621 from "00:00:00". In reference to the AIT information management table, since the AIT 2622 version that corresponds to the media time 2621 of "00:00:00" is "1", the AIT with the AIT 2200 version of " 1"is read from the file. Based on the details of the AIT, the Java program that corresponds to the program name 2204 that has information 2202"auto-start" control is activated. Then, the reproduction of the service continues, and when the position, in which the transport stream MPEG-2 corresponding to the media identifier 3502 of "TS_002" is being reproduced, indicates the time of means 2621 of "00:05: 00", referring to the AIT information management table, since the AIT 2622 version number that corresponds to the 2621 means time of" 00:05:00"is" 2"", the Java program that corresponds to the program name 2204 which has control information 2202 of "auto-start" is activated, and also, the Java program corresponding to the program name 2204 that has control information of "destroy" or "delete" is terminated, based on in the AIT with the AIT version number 2202 of "2." Here, referring to figure 21, the program name that has control information 2202 of "destroy" is "/ b / MusicXlet" and the name of program that has control information 2202 of "delete" is "/ z / StudyXlet", for therefore, in case the Java programs corresponding to these program names are executed at the time of means 2621 of "00:05:00", those Java programs are finished. Then, the reproduction of the service continues, and when the position, in which the transport stream MPEG-2 corresponding to the media identifier 2106 of "TS_002" is being reproduced, indicates the time of media 2621 of "00:20:00", in reference to the AIT information management table, in AIT 2622 version number that corresponds to the 2621 media time of "00:20:00" is "3", therefore, the Java program corresponding to the program name 2204 having control information 2202 of "auto-start" is activated, and also, the Java program corresponding to the program name 2204 having control information 2202 of "destroy" or "delete" is finished, based on the AIT with the AIT 2200 version of "3". The characteristic operation for the transmission recording and reproducing apparatus with the configuration described above can be described with reference to the same flow diagram as that used in the first embodiment. Figure 27 is a flow diagram showing an example of the operation of recording a service. Figures 28, 29 and 30 are flow charts showing an example of the operation for reproducing the recorded service in MPEG-2 transport stream format in the secondary storage unit. Any of them is the same as the one used in the first modality and therefore their descriptions are omitted. Thus, through the operation described above, with the AIT (1) as shown in figure 31, the activation and The termination of the Java program is carried out based on all the control information regardless of whether the service is being played in a trick play mode or in a normal play mode. As another example, when the AIT (2) is received as the updated AIT during the normal playback operation, only the Java program (Java program identifier = 301) of the row 2721 is activated. After this, when playback in trick play mode starts after "setRateO" is invoked with the value that is not factor 1.0, the Java program (Java program identifier = 301) of row 2721 is removed . When the AIT (2) is received during playback in trick play mode, the Java program is not executed. Thus, according to the present modality, in case the Java program is terminated due to the start of the reproduction in the trick playback mode, the user is informed of the state so that the user can know the Java program that will be executed originally, it is possible to adopt the method of returning to the normal or similar reproduction operation, and in this way the Java program can be prevented from being executed.

Third embodiment Some of the embodiments described above indicate embodiments of the present invention, but other embodiments may be considered without departing from the scope of the present invention. In the embodiments, a configuration for a cable system has been shown, but the present invention can be applied independently of the type of transmission system. For example, the present invention can be easily applied to a satellite system, a landwave system or a TV program distribution system using an IP network. Furthermore, since the present invention has no direct relationship to the differences between each transmission system, the present invention can be applied to an arbitrary transmission medium notwithstanding the transmission system. The present invention is also applicable regardless of whether the system 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 controlling a conditional access system has been introduced, but the adapter does not it is necessary for the implementation of the present invention. The adapter can have any format, and a configuration without the adapter is also possible. In such a case, in Fig. 16, the MPEG-2 transport stream of the tuner is input directly into the TS decoder. The present invention is applicable in such a case as well. In addition, the descrambling of the transport stream MPEG-2 by the adapter does not necessarily have to be carried out before the TS decoder. A configuration in which the adapter is in an arbitrary position and used to descramble the transport stream MPEG-2 can be easily implemented, 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 notwithstanding the coding format. A multiplexer multiplexer format can also be an arbitrary format. The present invention is applicable notwithstanding the multiplexing format. The visual presenter and loudspeaker may be contained within the transmission recording and reproducing apparatus, or an external visual presenter and loudspeaker may be connected to the transmission recording and reproducing apparatus. The present invention is applicable notwithstanding the location and number of the loudspeaker and the visual presenter. The present invention can be implemented even if the CPU itself is a system carrying out several processes, the processes being all or some of the decoding TS, AV decoding, AV coding and multiplexing. As a format for recording the service, the MPEG-2 transport stream can also be recorded directly into the recording area after it has been sent from the tuner, without passing 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 the Java virtual machines translate the bytecode into an executable form that can interpreted by the CPU, and pass the result to the CPU that executes it; the present invention is applicable in such a case as well. The above embodiments describe a method for its implementation with respect to the AIT in which the transport stream is obtained from In-Band; however, the method to refer to the Java program that the AM will execute does not depend solely on the AIT. In the assumed OCAP is used in the United States cable system, XAIT describing 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 of a downloaded program and recorded in the secondary storage unit, and others can be considered. Note that the first and second modalities show that, with the establishment of an indicator that fulfills trick playback when expanding an AIT, if the corresponding Java program meets trick playback it is shown. However, it can be shown by another method. In the present embodiment, a Java program is applied as a program to instruct reproduction of the trick playback mode, however, the present invention is applicable even to the case in which a program other than an Java program of such instruction. The format for recording a DSMCC file system and an AIT file may be arbitrary. The present invention can be implemented even by combining the method of obtaining, of the MPEG-2 transport stream, an AIT section through filtering, and the recording method, in a file, of a DSMCC section in an original format. The present invention can also be implemented even by combining the method of obtaining, from the MPEG-2 transport stream, a DSMCC section through filtering, and the recording method, in a file, of an AIT section in an original format. In the modalities, both the Java 3104 program suspension presentation unit and a privilege manager administrator are implemented; however, any of them can be implemented. In addition, the privilege manager administrator is achieved with a redial of the driver program codes, but the administrator can be achieved through an event notification instead. For the registration of a privileged driver, a configuration that requires a certain type of authentication or permission can be applied. For example, the configuration can request a permission request file as defined by the DVB-MHP specification and the OCAP specification.

The modalities describe the configuration of sequentially invoking both methods of "setPosition (start time of AIT)" and "setRate (1.0)" which are contained by the JMF, to reproduce the service from the start time of the AIT at normal speed. However, a new method that incorporates the two methods can be established again as an API. For example, when a method such as "rewindO" is invoked, both methods, "setPosition (start time of AIT)" and "setRate (1.0)" are executed sequentially and internally. Or, it is possible to have a configuration that defines a return value of a callback method "notifyO" of a privileged driver as "Boolean" and reproduces the service from the start time of the AIT at normal speed in the case of " true" . Although some exemplary embodiments of this invention have been described in detail above, those skilled in the art will readily appreciate that many modifications to the exemplary embodiments are possible without departing materially from the teachings and novel advantages of this invention. Accordingly, all of these modifications are intended to be included within the scope of this invention.

Industrial applicability In case a program that will be executed in synchronization with video and audio is not executed during playback, in a trick playback mode, of a service that includes this program, it is possible, with the recording and playback apparatus of transmissions and method of recording and reproducing transmissions in accordance with the present invention, to prevent the program from being overlooked by the user, by providing a system for notifying the viewer that the program is not executed because the service is being played in a trick play mode, and also a system for reproduce this service from the start time of the program in the jump to start operation. Therefore, there is a high possibility that the present invention is used particularly in a consumer apparatus industry with respect to the transmission recording and reproducing apparatus. For example, the present invention is useful as a cable STB and a digital TV or the like. Moreover, the present invention is also applicable in a device such as a cellular phone, as long as the device is equipped with a transmission reception function. 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.
