Description

Information record carrier and method

The application is that application number is " 02803785.5 (PCT/JP02/00219) ", and the applying date is on January 16th, 2002, and denomination of invention is divided an application for the application of " information record carrier and method ".

Technical field

The present invention is the carrier that can read and write, particularly relates to the carrier of the multi-medium data of the data that write down all forms that comprise animation image data, static picture image data, audio data etc.Further, the present invention relates to record the information in this carrier, perhaps, the apparatus and method of the information of regenerative recording.

Background technology

In recent years; DVD (Digital Versatile Disc (digital versatile disc))-ROM CD (also being called DVD-ROM simply) etc. read special-purpose cd; Except utilizing, also apply flexibly as the medium of the static picture of the animation of film etc., photo etc. and voice data (below be called " AV data ") as the medium of computer data.In recent years, further, as the recording medium that can write at any time, make to be called DVD-RAM CD (also being called DVD-RAM simply), the phase-change optical disk with several GB capacity has got into practicability.

Through complementing each other with coding standard Moving Picture Experts Group (MPEG) (animation expert group) or the practicability of MPEG2 as the international standard of digital AV data; We wait in expectation DVD-RAM can be not only as the medium of computer data, and as the record regeneration medium in audio video (AV) technical field.That is, we predict that it popularizes the medium of the tape of instead existing representational AV recording medium.

Use these with the CD of high capacity, how to write down the AV data, and realize that the performance that greatly surpasses existing AV equipment becomes key subjects from now on new function as purpose.

The maximum characteristic of utilizing CD to cause is to have improved access performance at random significantly.Suppose when inserting data at random, rewind the time that tape volume needs several minutes magnitudes usually.Relatively want slow several magnitude the search time (approximate number 10ms) in this and the disk medium.Thereby, in practicality, can not process accidental access device with tape.According to this access performance at random, can realize dispersed record with the impossible AV data that realize of existing tape with CD.

Fig. 1 is the block scheme of the drive unit of DVD registering instrument.Drive unit have the data of reading DVD-RAM CD 10 optical picking-up head 11,12,1 trace buffer 13 of ECC (Error Correcting Code (error correcting code)) processing unit, switch switch 14, cell encoder 15 and the decoder element 16 of the input and output of trace buffer 13.

As shown in the figure, in DVD-RAM CD 10, with 1 section (sector)=2KB as the least unit record data.Again, make 16 sections=1ECC piece, in ECC processing unit 12, carry out correction process.

Trace buffer 13 is because can be recorded in the AV data in the DVD-RAM CD 10, so can be used for variable bit rate record AV data more expeditiously.When explaining in more detail; Because with the read-write speed (Va) to DVD-RAM100 be that fixed rate is opposite; The complicacy of AV data and its content (if video then is an image) correspondingly changes bit rate (Vb), so can trace buffer 13 be used to absorb the poor of these 2 bit rate.Through more effectively utilizing trace buffer 13, with the AV data discrete be configured in the situation on the CD 10, also can the AV data be supplied with decoder element 16 continuously.In the situation of video, also can the AV data that send to cell encoder 15 be recorded among the DVD-RAM again.

In order more effectively to use this DVD-RAM as the huge storage capacity recording medium, in DVD-RAM, adopt UDF (Universal Disc Format (universal disc format)) file system, can insert through PC.In " Universal Disc Format Standard (universal disc format standard) ", disclosed the detailed situation of UDF file system.

Secondly, we explain the AV equipment that uses so far.Fig. 2 is the figure of the relation of the existing AV equipment of expression and medium, form.For example, if the user wants to see the image of videotape, then common, the user inserts VTR with videotape, carries out audiovisual through TV.Again, if want to listen to the music, then the user puts into CD player with CD and the CD radio cassette player is listened to through loudspeaker or earphone.That is, in existing AV equipment, there are a kind of medium for a kind of form (video or audio frequency).Therefore, the user needs often to change medium or AV equipment for the content of wanting to see or want to listen, and feels very inconvenient.

Again, in recent years because the popularizing of digital technology, in grouping software dvd video disc and in broadcast system digital satellite broadcasting practicability.In these backgrounds, exist the practicability of the innovation of digital technology, particularly mpeg format, this is self-evident.

Fig. 3 is the figure of the mpeg data stream that in above-mentioned dvd video disc and digital satellite broadcasting, uses.Mpeg standard has been stipulated stratum's structure shown in Figure 3.The data stream of the mpeg system layer that importantly final here application program is used is different in the communication medium system of such grouping media system of dvd video disc and digital satellite broadcasting that kind.The former is called " MPEG program data stream ", carries out data with the bag unit of the section (situation of DVD is 2048 bits) of recognizing the record unit that becomes dvd video disc etc. and transmits.The latter is called " MPEG transmitting data stream ", particularly through recognizing that ATM carries out the data transmission with the TS grouping unit of 188 bit bases.

We wait in expectation according to the MPEG as the coding techniques of digital technology and image and voice; Can freely handle the AV data with media-independent; But also exist this delicate difference, also do not have AV equipment and the medium corresponding up to now with routine package medium and communication medium both sides.Therefore, we wait in expectation because the appearance of the jumbo CD of DVD-RAM etc., can eliminate the inconvenience of with existing AV equipment the time, feeling.

Particularly we hope to be accompanied by the beginning of digital satellite broadcasting, and the CD of MPEG transmitting data stream can be likewise write down in appearance with the MPEG program data stream.

We hope that the DVD registering instrument can freely not show and the various format and contents of regenerating with single medium shown in Figure 4, single AV equipment under the user need not recognize the situation of each form.When describing particularly, Fig. 5 is an example of the menu screen in the DVD registering instrument.In this menu, need not recognize " 1) American-European film arenas " that on television image, can select digital satellite broadcasting under the situation of medium and record format of original record, the serial in morning of ground wave broadcast " 2) ", " 3) world cup finals " the user and from " 4) Beethovan " of the pirate recordings of CD.

Through using the CD of expectation as AV recording medium of future generation, the maximum problem when realizing this DVD registering instrument is how to manage AV data and the AV data stream that is made up of various forms uniformly.If only manage the form that has existed, then need not use special management method.But, use not only for the many forms that existed, and, be indispensable for the above-mentioned DVD registering instrument of realization for the management method that the format that occurs from now on also can both tackle.

According to by the difference that whether can handle the user interface that all AV data stream produce uniformly, possibly be created in the sort of inconvenience that existing example has suffered, promptly need the user to recognize that each content and form operate.Therefore, even if in various AV data stream, how to handle and carried out digitized data for digital broadcasting in emission one side and become a significant problem receiving a side.Particularly, in order to be implemented in the so-called time shift that also can utilize the various functions of the digital satellite broadcasting that newly begins behind the video, need be in the intact state of these data stream of emission these data stream of record.In the biography data stream of MPEG, can make a plurality of multiplexedization of video data stream (many scenes) simultaneously.

Further, even if for the new digital broadcasting that occurs in the future,, also require these broadcasting of time shift record even if for example its part of service content is also definite now.

As AV data for digital recording, apply flexibly example as the access property at random of the maximum characteristic of Digital Media, can enumerate entering (entry) point.In recent years, the user sets desired place (inlet point), and the necessity that can begin to regenerate from this place through the inlet point that inserts setting has improved.But also exist the self registering inlet point of pen recorder.Thereby, because have confusion reigned, so the data configuration that need be able to distinguish with mixing of these inlet points.

Summary of the invention

The objective of the invention is in order to make user easier understand ground management inlet point.Again, in order to be recorded in the data stream of using in the digital broadcasting (MPEG transmitting data stream stream) with various AV data stream, and the further data of regenerative recording.

Information record carrier of the present invention comprises: receiving element, and it receives the data stream that is made up of the numerical data of encoding; Input block, it receives the 1st positional information from the user, and wherein the 1st positional information is used to and at random inserts and the above-mentioned data stream and to setting in the regeneration path of above-mentioned data stream of regenerating; Resolution unit, it detects the variation and the output detection information of the attribute of above-mentioned data stream; Control module is obtained the 2nd positional information that comprises above-mentioned detection information and time information, and generates the management information of above-mentioned the 1st positional information and above-mentioned the 2nd positional information being registered with can identification mode; And drive unit, with above-mentioned management information and above-mentioned traffic logging in recording medium; The above-mentioned management information that comprises the identifying information that is used to discern above-mentioned the 1st positional information and above-mentioned the 2nd positional information.

Again, information recording method according to the present invention is realized as carrying out above-mentioned processed steps.Further, the present invention realizes as the information record program of carrying out through the computing machine that carries out above-mentioned processing.Therefore, can achieve the above object.Can information record program be recorded in the recording medium.

Control module also can generate the 1st table that comprises above-mentioned the 1st inlet point of registration and register the management information of the 2nd table of above-mentioned the 2nd inlet point.

If according to the present invention, then can obtain to discern the inlet point set according to data stream property and the management information of the inlet point of user's setting.According to management information, through selectively showing inlet point, the user can easily find desired sight from these information.

Embodiment

Below, we at length explain DVD-RAM, DVD registering instrument and the DVD phonograph of an example of the conduct carrier relevant with the present invention, pen recorder and regenerating unit with accompanying drawing.

Can in a CD, write down the AV data of various forms according to DVD-RAM of the present invention, and the data of management accounts uniformly.Therefore, can be with through making analog broadcasting be encoded into MPEG transmitting data stream video data recorded and being recorded in the CD as the MPEG transmitting data stream of digital broadcast transmitting.Again, can with fixed order regenerative recording these data in DVD-RAM.Therefore, the DVD-RAM relevant with the present invention has the management information that is used for irrespectively managing with the kind of the form of AV data the AV data stream.

At first, with reference to Fig. 6 A and Fig. 6 B, the data configuration of the data of declare record in DVD-RAM of the present invention.Data configuration on the CD 100 that Fig. 6 A representes can be familiar with through the file system of DVD-RAM CD 100.Fig. 6 B representes the structure of the physical segment on the CD 100.As shown in the figure, be provided with at the fore head branch of physical segment and introduce zone 31.In introducing zone 31, writing down and be used for stablizing the required standard signal of servo control mechanism and with the identification signal of other medium etc.With introducing zone 31 data area 33 is set continuously.In data area 33, write down active data in logic.33 front record is called the management information that the file system of information, volume is used in the data area.File system for example is the UDF form, so but because be that well-known technology is omitted the explanation to it here.Be provided with at last and draw zone 35.In drawing zone 35 with introduce regional 31 identical recordings standard signals etc.

Through file system, shown in Fig. 6 A, can be used as catalogue and file, handle the data in the CD 100.Shown in Fig. 6 A, manage under the DVD_RTAV catalogue of the total data that the DVD registering instrument is handled below ROOT (root) catalogue is direct.

In the file that the DVD of this example registering instrument is handled, exist the AV file that comprises audio video data (AV data) and comprise such 2 class files of management of information message file that are used to manage these AV files.In the example shown in Fig. 6 A, management information file is " VIDEO-RT.IFO ", and the AV file is the file " M_VOB.VOB " that comprises animation data.Again, the file that comprises the pictorial data that digital broadcasting uses is " D_VOB.VOB ".

Below, we specify these files.In addition, in this example, be object (Object) with each AV data definition.That is the various AV data stream that, in object, comprise MPEG program data stream etc.Here, through the AV data stream is carried out abstract as Object Snap, the management information of AV data stream is defined as unitized object information (ObjectI).

At first, we explain management information with reference to Fig. 7.As the example of management information, adopt the management information VIDEO_RT.IFO of AV file.Fig. 7 representes object, object information and program chains (the Program Chain of AV file; PGC) relation of information.Management information VIDEO_RT.IFO has PGC information 50,70 and all information of video management (VMGI:Video Manager General Information) 90 of regeneration order and recovery time of the data that the object information 80, definition of the record position of management object etc. regenerate in will the data in being recorded in DVD-RAM etc.Though data based their form of AV is that each is variant, also has the key element (for example time attribute) that can change jointly.Therefore, can carry out above-mentioned abstract.The AV data stream that will have a same form again, with the sequential storage of record in same AV file.

Object information (ObjectI) 80 by attribute information (AttributeI) 80b of the general information relevant (Object GI) 80a, object with object, with recovery time of object be transformed into access Figure 80 c of the address on the CD and represent any place of object access point (below; Be called inlet point), about the inlet point table 80d formation of PGC information 50.

For the conversion utilization of carrying out between time shaft and data (ranking) axle 1 inserts Figure 80 c.Inserting Figure 80 c has for each object unit data corresponding with time zone and address area.This be because as later described, 1 to as if by a plurality of object unit (VOBU) formations.Needing to insert Figure 80 c is because the AV data stream generally has 2 benchmark of time shaft and data (ranking) axle, between these 2 benchmark, does not have correlativity completely.For example, corresponding with the complicacy of image quality in situation as the MPEG-2 video of the international standards of video data stream, becoming main flow with the variable-digit speed mode that changes bit rate.At this moment, because from the data volume of front and disproportional relation between the recovery time, so can not to carry out with the time shaft be the access at random of benchmark.Therefore, the access Figure 80 c that needs the correlationship of stipulated time and data.

When pictorial data and the voice data of controlling recording in DVD-RAM100, i.e. utilize PGC information 50,70 during the regeneration of object.A unit when PGC information 50,70 expression DVD phonographs carry out data reproduction continuously.That is the object of PGC information 50,70 expression regeneration and represent in this object the regeneration sequence of the unit information between the renewing zone 60,61,62,63 arbitrarily.We will state unit information 60 etc. in the back.Can PGC information be divided into the user-defined PGC information 70 such 2 types that the original PGC information 50 that generates automatically for the DVD registering instrument comprises whole record objects when the long-pending record of object and user can freely define the regeneration sequence.

In addition, inlet point table 80d regulation a inlet point (being also referred to as original inlet point) of the object information 80 of front explanation about original PGC information 50.Each unit information about in the user-defined PGC information 70 of inlet point (being also referred to as user's inlet point) regulation of user-defined PGC information 70 for example is arranged on the inlet point table 72 in the unit information 71.With original inlet point automatically, be set in the object self of regulation in the object information 80 by the DVD registering instrument.On the other hand, user's inlet point is at random set the regeneration path of object by the user.

In addition, also can inlet point table 80d be arranged in the original PGC information 50.If in original PGC information 50, then also can be provided with accordingly with each unit information, also can be used as the information that is not included in each unit information and in original PGC information 50, be provided with 1.Again, the inlet point table that comprises in the user-defined PGC information 70 can not be provided with 1 of each unit information yet, can be used as the information that is not included in the unit information yet and in user-defined PGC information 70, is provided with 1.

PGC information 50,70 formation and functions, except user-defined PGC information 70 by user definition with have the inlet point table 72, be identical.Therefore, below, we mainly at length explain original PGC information 50.To state in the back about inlet point table 72,80d.

As shown in Figure 7, original PGC information 50 comprises 1 unit information 60,61,62,63 at least.Unit information 60 grades are specified the object of regeneration, and specify between the renewing zone of this object.Usually, PGC information 50 is with a plurality of unit of certain journal.The regeneration order when the object of each unit appointment of regeneration represented in proper order in the record of the unit information in PGC information 50.

A unit information; For example; In the unit information 60, comprise the kind of the object of representing its appointment type information (Type) 60a, object after state many scene informations (View_Type) 60b, as start position information (Start) 60d in object ID (Object ID) 60c of object identifying information, the object on time shaft and end position information (End) 60e in the object on time shaft.When data reproduction, read the unit information 60 in the PCG information 50 in order, only separate between renewing zone by the unit appointment, regeneration is by the object of each unit appointment.

For the object information with abstract is applied to actual AV data stream, need more specific.This consideration, other succession of level of in the objects point model, seeing particularly, collects object information as mother, and the structure that will in each AV data stream is used, specialize is to understand easily as subclass.Fig. 8 is the figure of expression from each data stream management information of object information derivation.As shown in Figure 8, in this example, as the subclass of object information, each subclass of definition animation subclass, DVB subclass, data stream subclass.The animation subclass is the animate object information (M_VOBI:Movie Video Object Information) 82 of the object information (MPEG transmitting data stream) used of expression video.The DVB subclass is the DVB object information (D_VOBI:Digital Video Object Information) 86 of the object information of expression digital broadcast data (MPEG transmitting data stream) usefulness.The data stream subclass is the data stream object information (SOBI:Stream Object Information) 89 of the object information of representing that the data stream of special-purpose is not used.Below, we explain each object information.

Animate object information 82 has general information (M_VOB_GI) 82a of MPEG transmitting data stream, traffic flow information (M_VOB_STI) 82b, time diagram 82c and the inlet point table 82d of animate object.

The general information of animate object information 82 (M_VOB_GI) 82a comprises the identifying information (M_VOB_ID) of animate object, the record time information (M_VOB_REC_TM) of animate object, the information zero hour (M_VOB_V_S_PTM) of animate object, the information finish time (M_VOB_V_E_PTM) of animate object.The traffic flow information of animate object (M_VOB_STI) 82b comprises the bar number (AST_Ns) of the video data stream information (V_ATR) that begins from the coding mode of video data stream, audio data stream and the audio data stream information (A_ATR) that begins from the coding mode of audio data stream.Time diagram 82c is included in the preceding leading address of the animate object in the AV file, the recovery time (VOBU_PB_TM) and the size of data (VOBU_SZ) of each animate object unit (VOBU).Here, the minimum access unit in animate object unit (VOBU) the expression animate object (M_VOB), we will state its detailed situation in the back.

DVB object information (D_VOBI) 86 has general information (D_VOB_GI) 86a, traffic flow information (D_VOB_STI) 86b, time diagram 86c and the inlet point table 86d of MPEG transmitting data stream.

The general information of digital broadcasting object (D_VOB_GI) 86a comprises the identifying information (D_VOB_ID) of digital broadcasting object, the record moment (D_VOB_REC_TM), the information zero hour (D_VOB_V_S_PTM) of digital broadcasting object of digital broadcasting object, the information finish time (D_VOB_V_E_PTM) of digital broadcasting object.The traffic flow information of digital broadcasting object (D_VOB_STI) comprises the information (PROVIDER_INFR) of the additional information of providing and delivering in the storage digital broadcasting.Time diagram 86c is included in the preceding leading address of the digital broadcasting object (D_VOB) in the AV file, the recovery time (VOBU_PB_TM) and the size of data (VOBU_SZ) of each object unit (VOBU).

Data stream object information (SOBI) 89 has general information (SOB_GI) 89a of digital data stream, traffic flow information (SOB_STI) 89b, time diagram 89c and the inlet point table 89d of digital data stream.

The general information of digital data stream (SOB_GI) 89a comprises the identifying information (SOB_ID) of data stream object, the record moment (SOB_REC_TM), the information zero hour (SOB_S_TM) of data stream object of data stream object, the information finish time (SOB_E_TM) of data stream object.The traffic flow information of SOB (SOB_STI) 89b comprises the information (PROVIDER_INF) of storage as the additional information of data stream dispensing.Time diagram 89c is included in the recovery time (SOBU_PB_TM) of the preceding leading address of the interior SOB of AV file and each data stream object unit (SOBU).Big or small identical the fixing of the size of each SOBU and above-mentioned EEC piece.Here, the minimum access unit in data stream object unit (SOBU) the expression data stream object (SOB), we will state its detailed situation in the back.

Like this, specialize through the object information that makes abstract, as shown in Figure 8, for each AV data stream, definition corresponding data flow message file.

Secondly, with reference to Fig. 9,, the corresponding relation of digital broadcasting object information (D_VOBI) 86 and unit information 60 is described as 1 concrete example of object information (ObjectI).

If the value of the type information of appointment (Type) is " D_VOB " in the unit information 60, mean that then this unit is corresponding with object with digital broadcasting.In addition, mean that then this unit is corresponding with animate object, and is if the value of type information is " SOB ", then corresponding with the data stream object if the value of type information is " M_VOB ".

When the value by the type information (Type) of unit information 60 appointments is " D_VOB ", given scenario type information (View_Type) in unit information.Scene type information specifies in whether there are many scenes (afterwards stating) in the suitable unit, when existing, specifies several scenes.In the scene type information, when having many scenes, set maximum scene number, when not existing, set 0.Again, utilize object ID (Object ID), can retrieve corresponding object information (VOBI).This can be through utilizing, and for example, (D_VOB_ID) correspondence realizes one to one for the object ID of expression digital broadcasting object and the digital broadcasting object ID (identification number) that in general information (D_VOB_GI) 86a of digital broadcasting object information (D_VOBI) 86, comprises.Like this, through with type information (Type) and object ID (Object ID), can seek the object information corresponding with unit information 60.

Start position information in unit information 60 (Start) is corresponding with the information zero hour (D_VOB_V_S_PTM) of digital broadcasting object.If the value according to each expression is same value (constantly), then this unit is represented from the regeneration of the front of digital broadcasting object.When the value of start position information (Start) was bigger than the information zero hour (D_VOB_V_S_PTM), the regeneration from the way of digital broadcasting object was represented in this unit.At this moment, only with poor (mistiming) of value with the value of start position information (Start) of the information zero hour (D_VOB_V_S_PTM), from the front delay of digital broadcasting object and this unit of regenerating.Again, the end position information (End) of unit also has same relation with the information finish time (D_VOB_V_E_PTM) of digital broadcasting object.

Like this; According to the information zero hour (D_VOB_V_S_PTM) and the information finish time (D_VOB_V_E_PTM) in general information (D_VOB_GI) 86a of the start position information in unit information 60 (Start), end position information (End), digital broadcasting object information (D_VOBI) 86, regeneration beginning and the end position that can access this unit are as the relative time in the animate object.

Time diagram 86c in the digital broadcasting object 86 is the file that is made up of the recovery time of each animate object unit (VOBU) and size of data.Through can the regeneration in the animate object of above-mentioned unit being begun and finish relative time to be transformed into address date with reference to this time diagram 86c.In addition, animate object unit (VOBU) is in the VOB of the AV of presentation graphs file, the set of a plurality of bags that surrounded by heavy line.In addition, each bag has the size identical with section, utilizes the bag memory image data more than 1 or 1.

Then we explain the concrete example of the address mapping of reference time figure with reference to Figure 10 A～Figure 10 F.

Figure 10 A representes to show the digital broadcasting object (D_VOB) that the video on the time shaft shows.Figure 10 B representes the time diagram by the recovery time length of each animate object unit (VOBU) and size of data formation.Figure 10 C is illustrated in the digital broadcasting object of performance on data (section row) axle.Figure 10 D representes the bag row of the part of amplifier digital broadcast object (D_VOB).Figure 10 E and Figure 10 F represent video data stream harmony frequency data stream respectively.

Animate object (D_VOB) is the MPEG transmitting data stream.The MPEG transmitting data stream flows divide into groups (PES grouping) to video data stream, audio data in order to be changed, and comprises the sequence of a plurality of this groupings (PES grouping) bag.

Transmission grouping (TS grouping) has the fixed size of 188 bits.Because 1 section of DVD-RAM has 2048 bits, thus in section with after the header information stated write down a plurality of transmission and divide into groups (2048 bits/188 bits=10TS divides into groups).

In transmitting data stream, make 1 data stream of multiplexedization of video packets (V_PKT) harmony frequency division group (A_PKT) formation of TS packetizing.Figure 10 C～Figure 10 F representes the appearance of multiplexedization.

Again, as the general name of transmitting data stream and program data stream, the mpeg system data stream, the video harmony frequency data stream for multiplexedization of synchronizing regeneration has time tag in data stream.

In the situation of transmitting data stream, as time mark is the regeneration PTS (Presentation Time Stamp (express time mark)) constantly of expression frame.The information zero hour (D_VOB_V_S_PTM) of above-mentioned digital broadcasting object, the information finish time (D_VOB_V_E_PTM) of digital broadcasting object are the time informations that this PTS is tried to achieve as benchmark.

Then, we explain animate object unit (VOBU).Minimum in animate object unit (VOBU) the expression digital broadcasting object (D_VOB) inserts unit.The MPEG video data stream is not only used the image compression of the spatial frequency characteristic in the frame of video, and utilizes between the frame of video, and promptly the image compression of the dynamic perfromance on the time shaft realizes high efficiency image compression.This means that when certain frame of video of elongation need the information on the time shaft, promptly the information of future or frame of video in the past can not be extended frame of video individually.In order to address this problem, in general MPEG video data stream,, insert frame of video (I-image) without the dynamic perfromance on the time shaft with about 1 ratio in 0.5 second, the raising program inserts property.

Animate object unit (VOBU) is that bag with the front data that comprise this I-image is as the front, as the set up to the interval regulation of the bag of the direct front of the bag of the front data that comprise next I-image.In time diagram, constitute by the size of data (TS packet count) of these each object unit (VOBU) and the recovery time (symbols number) of the frame of video in the object unit (VOBU).

In addition, the front data of I-image are not necessarily the front that TS divides into groups.Therefore, have final data in certain object unit (VOBU) be present in next object unit (VOBU) in the situation of data identical TS in front in dividing into groups.Therefore, the size of data of object unit (VOBU) is to comprising next object unit (VOBU), the TS packet count of the direct front that the TS of the front data of promptly next I-image divides into groups.

For example, the difference of expression value of supposing the information zero hour (D_VOB_V_S_PTM) of value that the Start by the unit representes and digital broadcasting object is 1 second (60 symbols).Through be multiplied by the recovery time of each object unit (VOBU) in the time diagram 86c from the front, can try to achieve from the regeneration zero hour of each object unit of the front of digital broadcasting object (D_VOB).Same size of data (TS packet count) through being multiplied by each object unit can be tried to achieve from the address of each object unit of the front of digital broadcasting object (D_VOB).

In the situation of this example; Because the object unit (VOBU) of 24,30,24 symbols arranged side by side respectively, count 1 second frame of video after (60 symbols) from the front of digital broadcasting object (D_VOB) and be included in from the 3rd object unit (VOBU#3) that the front is counted so can try to achieve from the front of digital broadcasting object (D_VOB).Again; Because counting from the front of digital broadcasting object, the data volume of object unit (VOBU) is respectively 1250,908,1150 TS groupings; So can try to achieve the preceding leading address of the 3rd object unit (VOBU#3) is that the 2158th TS of counting from the object front divides into groups, and promptly the 8th of 215 sections the TS divides into groups.As a result, through adding 5010 sections as the preceding leading address (ADR_OFF) of D_VOB in the AV frame, can try to achieve the preceding leading address of the data that begin to regenerate.

In above explanation, suppose the regeneration of the frame of video of the 60th frame of counting from the front.As explaining, because in nature, can not decode and regenerate, so in order to regenerate, regenerate from the front of the object unit (VOBU) nearby that departs from 6 symbols from the front of I-image from frame of video arbitrarily at the MPEG video.But, only these 6 symbols to be decoded through demoder, and do not carry out work with showing, video symbols that can the appointment from the unit is regenerated.Can with above-mentioned explanation likewise obtain with the regeneration ending of the corresponding digital broadcasting object of the end position of unit constantly and the address in the AV frame.

In addition, in the PROVIDER_INFR symbols in the traffic flow information (D_VOB_STI) of digital broadcasting object, comprise the intrinsic information of the ID that discerns broadcaster and each broadcaster.

Secondly, we explain animate object information (M_VOBI).Because animate object information also is the subclass that derives from from object information, so identical with digital broadcasting object information basically.Big difference is that animate object (M_VOB) is to the earthwave generation of recording.That is, and generate digital broadcasting object (D_VOB) relatively through direct record from the data of digital broadcast satellite emission, animate object is to have very big difference through registering instrument this point of AV data stream that obtains of encoding.Address mapping about reference time figure is identical with D_VOB.

For example, 1 section of DVD-RAM has 2048 bits, and the grouping in M_VOB also has the fixed size of 2048 bits.So, in the situation of animate object (M_VOB), can be treated to=1 section of 1 bag.Because for DVD-RAM can reading and writing data the unit section of being, so can be from the section to the section definition animate object unit, ground.About identical with D_VOB basically with reference to the address mapping of T (time) figure.In addition, the time diagram that in the address mapping of M_VOB, uses replaces representing with packet count the size of data of VOBU as the D_VOB situation, also can show it with the bag numerical table.

Secondly, our declarative data flow object information (SOBI).Because the data stream object information also is the subclass that derives from from object information, so identical with digital broadcasting object information basically.Big difference is with in digital broadcasting object (D_VOB), can to resolve its data stream contents with registering instrument relative, in data stream object (SOB), can not resolve its content with registering instrument.Digital broadcasting object (D_VOB) is as animate object (M_VOB), and self encodes registering instrument to data.Therefore, the data configuration of data stream is self-evident, and registering instrument can be resolved., because in data stream object (SOB), registering instrument does not carry out record to data with resolving; So for example; When in order data to be carried out copyright protection etc. and to carry out encipherment, perhaps, when because be new service; So when registering instrument does not have corresponding decoder etc., registering instrument is not known the internal structure of data stream.

Therefore, when deal with data flow object (SOB), can not make above-mentioned time diagram.Therefore, in this example, use the ATS (Arrival Time Stamp (due in mark)) of the due in of representing that each TS in the MPEG transmitting data stream divides into groups to make time diagram.

Figure 11 A and Figure 11 B represent that the TS in the data stream object (SOB) divides into groups and the relation of header information.In data stream object (SOB), the header information of a plurality of ATS of comprising and TS are divided into groups alternatively to be configured in 1 section.In this example, because header information is 4 bits, it is 188 bits that TS divides into groups, so in 1 section, dispose the right of 10 header information and TS grouping.Use this ATS, the moment in the specific data flow object (SOB).

The set that utilization is called SOB unit (SOBU) is defined in the object among the time diagram 89c (Fig. 8) of data stream object (SOB).In data stream object (SOB), because can not resolve its content, so the fixing size of data of SOBU.In this example, the size of data that makes SOBU is the size of ECC piece.So, through the fixing size of data of SOBU, in the time diagram 89c of data stream object (SOB), need not specify size.Therefore, time diagram is the table of the front TS of object unit (SOBU) due in (ATS) information of dividing into groups.In the situation of data stream object (SOB), the information zero hour (D_VOB_V_S_PTM) of object, the information finish time (D_VOB_V_E_PTM) of object are respectively the front of object or the due in (ATS) that final TS divides into groups.

About the address mapping of reference time table, identical with D_VOB basically.But at the timetable of the address mapping that is used for SOB, the size of data of each object unit (VOBU) is fixed as the situation of D_VOB, representes without packet count.

In addition, replace giving ATS, the TS packetized memory that also can be used in the MPEG transmitting data stream PCR (Program Clock Reference (program clock with reference to)) rise time figure.PCR representes the input moment of the demoder that each TS divides into groups.At this moment,, PCR divides into groups, so slotting in need be in registering instrument these values being carried out because not necessarily giving whole transmission.

In the PROVIDER_INF symbols in the traffic flow information (S_VOB_STI) of data stream object, identical with the situation of digital broadcasting object, comprise the intrinsic information of the ID that discerns broadcaster and each broadcaster.

Figure 12 representes the formation of all management information in the CD of this example.Putting down in writing the data configuration that arrives this explanation among Figure 12.Below, we explain all management information.Except above-mentioned PGC information 50,70 etc., also have all video management information 90 and various file information table 92,94,96 according to the CD of this example.

All video management information VMGI90 are about all management information of CD, for example, comprise the start address of original PGC information 50, user-defined PGC information 70 and various file management table 92,94 etc., i.e. dot information.Through with reference to this dot information, can insert PGC information 50,70 and file management table 92,94 etc.

Here, we explain file management table shown in Figure 12 92,94,96.Each file management table the 92,94, the 96th is used to manage the table of the data file that is made up of object, and every kind of object is set.The data streaming file admin table 96 of data streaming file of digital broadcasting file management table 94 and management accounts data stream object of animation file with animation file admin table 92, management accounts animate object of the file of management accounts digital broadcasting object.

As stated, according to the object ID special object information of the unit information in the PGC information, but at this moment, through the address of file management table 92,94,96 special object information.Therefore, file management table 92,94,96 has the information of object information number, the object ID of management, size of object information etc.For example, when the object ID order of representation, according to the object ID by the unit information appointment, whether the object information that can be familiar with this appointment is by which object information in the object information of file management table management.After this, through calculating from the order of this object information and file size, can access the address of the object information of this appointment with the start address of file management table compensation rate as benchmark.

Shown in figure 12, digital broadcasting file management table 94 is tables of the digital broadcasting file of management accounts digital broadcasting object.Digital broadcasting file management table 94 comprises file control information (D_AVFITI) 94h that comprises digital broadcasting object information (D_VOBI) 94a, 94b......, the digital broadcasting object information number of this table 94 management, the size of digital broadcasting object etc.Only the digital broadcasting object information number to recording and narrating among this file control information 94h is recorded in digital broadcasting object information on the CD continuously.Digital broadcasting object information 94a...... as stated, comprises general information (D_VOB_GI), traffic flow information (D_VOB_STI), time diagram and inlet point table.Again, time diagram comprises the demonstration time and the size (VOBU_ENT) of each digital broadcasting object unit (VOBU).In addition, the data streaming file admin table (S_AVFITI) 96 of animation file admin table (M_AVFITI) 92, the record data flow object of record animate object also has the data configuration identical with digital broadcasting file management table 94.

In original PGC information 50, unit information with the journal that will regenerate.Unit information has corresponding informance (type and object ID) and the regeneration block information in object (Start and End) to object information.Can will represent that information conversion between the renewing zone of unit becomes the address information of object virtual condition through the access figure in the object information.

As stated, except not or the inlet point off-balancesheet is arranged, the data configuration of user-defined PGC information 70 is identical with the data configuration of original PGC information 50.

As stated, the management information of earlier the AV data stream being used is carried out abstract, can irrespectively define the PGE information as the regeneration control information for each AV data stream format and intrinsic information, can manage the AV data stream uniformly.Therefore, can realize the user can be under the situation of not recognizing the AV data stream environment of reproducing AV data stream freely.

Again, through above-mentioned data configuration, i.e. box lunch when being taken into new AV form is also preferably stipulated the management information that derives from from object information with existing AV form identically.Therefore, can simply new form be taken in the data configuration.

Secondly, we at length explain the inlet point table.Inlet point is the access point that begins to regenerate from the anywhere of broadcast program of video on CD for the user.For example; As putting down in writing among Fig. 7; To be recorded in about the inlet point of original PGC information 50 among the inlet point table 80d that is arranged in the object information 80; On the other hand, will be recorded in each unit information that is arranged on user-defined PGC information 70, for example in the inlet point table 72 in the unit information 71 about the inlet point of user-defined PGC information 70.

Identical with starting position, the end position of unit, in the situation of digital broadcasting object (D_VOB) and animate object (M_VOB), specify inlet point with PTS, in the situation of data stream object, specify inlet point with ATS.

The setting of inlet point is carried out as follows.At first, digital satellite broadcasting also comprises a plurality of additional informations except the AV data stream.According to being stored in information Recognition and 1 the AV data stream that program is suitable in the special table that is called program description information PSI (Program Specific Information), program description information PSI and information on services SI (Service Information) are the information of the regeneration of control transmission data stream in digital satellite broadcasting.Specifically, be through TS packet group with 1 suitable AV data stream of program from the video harmony frequency data stream corresponding with being included in a plurality of programs the transmitting data stream, extract a plurality of TS that constitute this program out and divide into groups that row obtain.Can divide into groups to be listed as according to a plurality of TS that are attached to specific this program of formation of packet ID information (PID) in each grouping.This packet ID information (PID) is recorded in the flowchart (PMT) in the PSI information corresponding with this program.Digital satellite broadcasting can realize comprising the interaction information of data broadcasting etc., the service that can not use existing analog broadcasting to realize.

In digital broadcasting, have the function that is called many scenes, can in 1 program, comprise a plurality of animations arranged side by side on the time.About many scenes, in ARIBTR-B15, have detailed record, but in this manual, we explain the data configuration of realizing many scenes with reference to Figure 13 simply.Figure 13 is the figure of data configuration of the Event Information Table EIT (Event Information Table) of the many scenes of expression explanation.

When the scape of regeneration home court, with reference to the table of component_group_id=" 0x0 ".In the table of component-_group_id=" 0x0 ", judge that the component_tag of corresponding animation data stream is V0.Secondly, with reference to the table of user prompt unit because the group_PID of V0 equals " 0x01 ", thus judge component_tag for the TS grouping row corresponding data flow of the PID that obtains 0x01.Equally, judge that the audio data stream corresponding with the home court scape is that the TS with PID of 0x02 divides into groups to be listed as.In digital video,, show the home court scape of many scenes program to the user through these data stream are decoded.

Again, in addition, the AV data stream of digital broadcasting also comprises a plurality of additional informations except acoustic information.In these additional informations, have about can by the user carry out the data broadcasting of reciprocation operation information, can not see towards father and mother's control information of adult's content etc. in order to make the minor.Send information with rotating disc type tape mode about data broadcasting.So-called rotating disc type tape mode refers to the data of giving each same content of fixing time storage for each file or than its little unit weight recurrence.Because, also can repeat to send data, so can obtain data necessary when needing even if be called unidirectional communication mode of broadcasting through adopting rotating disc type tape mode.

When audio-visual data is broadcasted, if carry out audiovisual, so be high efficiency then because can in the short time, obtain the data that need from the front of rotating disc type tape.If can jump over, then can realize the audiovisual of high efficiency time shift because father and mother's control is forbidden the part of minor's audiovisual and regenerated again.

The user is a lot of in the situation that these switching points insert program.That is, through these switching points can be inserted the program that is recorded in the CD expeditiously as the inlet point user.Can on registering instrument, detect automatically and this inlet point of automatic setting.

On the other hand, exist the user sight of liking etc. to be set the situation of inlet point alone.For the user, oneself recognize and the inlet point set is different with inlet point by the registering instrument automatic setting.Because when showing them simultaneously and selecting, take place chaotic, so need the data configuration that can distinguish.

In this example, through setting attribute information at each inlet point, the inlet point that the inlet point of difference automatic setting and user set.Figure 14 representes to set at inlet point the inlet point table of attribute information.The inlet point table has for each inlet point, and the expression user recognizes and specify the USER_EP flag information of this inlet point.For example,, give distinguishing mark 1,, give distinguishing mark 0 for original inlet point for user's inlet point.Through reference mark information, registering instrument or phonograph can show to the user whether this inlet point is set by the user clearly.

Further, the inlet point table for each inlet point have expression as the PG_Change of program variation point, expression as the PSI_SI of the variation point of the PSI/SI information in the transmitting data stream, in the expression change transmitting data stream mpeg data stream attribute SQH_Change, expression data carousel formula tape the place, front Data_Top, expression data carousel formula tape content alteration point Data_Change, expression PMT variation point PMT_Change, expression data event renewal point DE_Change, representation module renewal point Module_Change, Aud_Change that expression change voice attribute becomes each flag information and represent that for corresponding the Multi_View symbols of the scene number of program, father and mother control (pupillary audiovisual is limited) information symbol group with many scenes.The inlet point table has the link information of the file beyond text managemant information and the AV data stream in the CD for each inlet point.This link information in the situation of digital broadcasting object (D_VOB) and animate object (M_VOB), is the PTS for each inlet point, in the situation of data stream object, is ATS.

When the user sets inlet point; No matter whether set USER EP sign, registering instrument can both show whole inlet points, their attribute information (PG_Change, PSI_SI, SQH_Change, Data_Top, Data_Change, PMT_Change, DE_Change, Module_Change, Aud_Change, Multi_View symbols, father and mother's control information) to the user.The user labels to needs oneself editor's inlet point from whole inlet points of these demonstrations and their attribute information.When setting tagged inlet point, on tagged inlet point, set USER_EP sign " 1 " by registering instrument by registering instrument.When having added mark once more on the inlet point of before the user, setting, keep until this USER_EP sign " 1 ".

Also exist the user to set the situation of inlet point in the place of not detecting automatically again.At this moment, the user selects desired sight through the operation note appearance, sets inlet point.When being registered in this inlet point in the inlet point table, set USER_EP sign " 1 " by registering instrument.

Registering instrument, in PGC edits, only to user's display setting the inlet point of USER_EP sign.Therefore the user can be less than the trouble that caused by the detected inlet point of automatic setting under situation about oneself not recognizing, only the inlet point of selection needs carries out PGC and edits.

If inlet point table shown in Figure 14, the inlet point table 80d that then sets object information 80 is just enough.But, also can individually be set in the user-defined PGC information 70 (Fig. 7) as to this explanation.At this moment, both can comprise also and can not be included in the unit information.

Through with the inlet point of other table management automatic setting shown in Figure 15 and the inlet point that the user sets, can distinguish each inlet point.Figure 15 is the inlet point table of expression automatic setting and the figure of the inlet point table that the user sets.Because be ability automatic setting inlet point when writing down, preferably only in original PGC information, set the inlet point table of automatic setting by registering instrument.The attribute information of the inlet point of front explanation is recorded in this table.On the other hand, the inlet point table of the user being set is set in the unit information of user-defined PGC information 70 (Fig. 7).In addition, can the inlet point table of automatic setting be set in the object information 80 (Fig. 7) yet and be set in the original PGC information 50 (Fig. 7).

In addition, as other example, also the inlet point table corresponding with each scene can be set in above-mentioned many scenes.Figure 16 is the figure of the inlet point table that is provided with accordingly with each scene of expression.Therefore, can easily manage the inlet point of each scene.The recording of information symbols that also can in each inlet point table, set a property, this is self-evident.

Secondly, we explain the phonograph model of the above-mentioned CD of regeneration with reference to Figure 17.Shown in figure 17, phonograph 1700 have from the optical picking-up head 1701 of CD 100 sense datas, carry out the ECC processing unit 1702 of the error correction etc. of sense data, temporarily store the sense data after the error correction trace buffer 1703, regeneration animate object (M_VOB) and digital broadcasting object (D_VOB) etc. transmitting data stream TS demoder 1706 and control the control module 1711 of the each several part of phonograph 1700.

Phonograph 1700 further, has the digital interface 1704 that is used for the AV data stream is supplied with the outside.Therefore, also can the AV data stream be supplied with outside through the communication protocol of IEEE1394 and IEC958 etc.This particularly when being taken into new AV form, when not through phonograph 1700 inner demoders but output to outside AV equipment through digital interface 1704, is effective during regeneration in this AV equipment.When phonograph 1700 is supported new AV form, preferably further have with other demoder and likewise be connected, with new AV form corresponding decoder 1709 with trace buffer 1703.

Below we explain the reproduction operation of phonograph 1700.Phonograph 1700 utilizes optical picking-up head 1701, the data of playback record on CD 100.1702 pairs of data of reading of ECC processing unit are carried out the ECC processing, obtain transmitting data stream (TS).The transmitting data stream (TS) that will pass through the ECC processing is stored in the trace buffer 1703.When transmitting data stream (TS) can be decoded, control module 1711 made selected cell 1710 work, is connected with demoder 1706 with trace buffer 1703.Demoder 1706 separates into video data and audio data through coding with transmitting data stream (TS), respectively they is decoded.And output is through the video data and the audio data of decoding.In addition, when control module 1711 judges that transmitting data stream (TS) can not be decoded, preferably be provided with and decode with new AV form corresponding decoder 1709.

Secondly, we explain for above-mentioned CD with reference to Figure 18, the formation and the work of the DVD registering instrument of record data.Because the DVD registering instrument also can the data of regenerative recording in CD, so we also will explain its reproduction operation in the back.

Shown in figure 18; DVD registering instrument 1900 have as accept to user's demonstration and from all system control units 1902 of user interface (user I/F) unit 1901 of the input block of user's requirement, management and control DVD registering instrument 1900, receive VHF and UHF analog tuner 1903, simulating signal is transformed into digital signal, further be encoded into the MPEG transmitting data stream scrambler 1904, receive the digital tuner 1905 of the data stream of digital satellite broadcasting, the display unit 1907 of resolution unit 1906, televisor and loudspeaker etc. that the data stream (MPEG transmitting data stream) that is made up of the numerical data through coding is resolved and the demoder 1908 that the AV data stream is decoded.Demoder 1908 not only comprises demoder shown in Figure 17 1706 but also comprises the demoder 1709 that appends.Further, DVD registering instrument 1900 has the trace buffer 1910 that digital interface unit 1909, temporary transient storage write the data of DVD-RAM, the motor that makes the DVD-RAM100 rotation, data is write the laser radiation unit of DVD-RAM100 and have the driver 1911 of optical picking-up head etc.Digital interface unit 1909 is the interfaces that data outputed to external unit according to the communication protocol of IEEE1394 etc.

In DVD registering instrument 1900, the user interface section 1901 initial requirements of accepting from the user.User interface section 1901 will send system control unit 1902 from user's requirement to, and 1902 pairs of requirements from the user of system control unit make an explanation and are issued to the processing requirements of each module.

Below, we are the work when digital broadcasting is recorded with reference to Figure 19 explanation from user's requirement.Figure 19 is the flow diagram that the video of expression DVD registering instrument 1900 (Figure 18) is handled.

To send system control unit 1902 to from user's the requirement that digital broadcasting is recorded through user interface section 1901.System control unit 1902 requires digital tuner 1905 receiving digital broadcasts, further, requires resolution unit 1906 that this MPEG transmitting data stream is carried out data parsing.Resolution unit 1906 is at first extracted the information zero hour (D_VOB_V_S_PTM) as generating the required information of digital broadcasting object information (D_VOBI) from the MPEG transmitting data stream, sends to system control unit 1902 (step S191).

Resolution unit 1906 determines further and cuts apart the object unit (VOBU) in the MPEG transmitting data stream that time span and the size that will scheme required object unit the rise time send to system control unit 1902 (step S192).In addition, can decision objects unit (VOBU) through the I-image in the detected transmission data stream.

To send trace buffer 1910 to from the MPEG transmitting data stream that digital tuner 1905 sends over through resolution unit 1906.System control unit 1902 is to driver 1911 output record requirements, and driver 1911 takes out and is stored in the data in the trace buffer 1910, is recorded in (step S193) in the DVD-RAM CD 100.At this moment, whether system control unit 1902 from the configuration information of file system, is recorded on each CD consistently with, sends indication to driver 1911.

Resolution unit 1906 is kept watch on the MPEG transmitting data stream in receiving with detected object unit time information, detects its attribute change (step S194).Below, we enumerate the example of the concrete detection method in the BS digital broadcasting.At this moment, recording unit has the storer of information before only preserving with certain data volume for the variation point of each information of detecting (a)～(k).

In addition, the detection method of enumerating here is an example, also exists and by a part of inconsistent situation in the ARIB predetermined data structure, still can certainly detect with the data configuration consistent with the ARIB regulation.

(a) PG_Change: the event_id (Figure 20) among the EIT in the reference number broadcast data stream (Event_Information_Table), additional when in this value, changing.

(b) PSI_SI: be the table that constitutes the PSI/SI information in the digital broadcast data stream; With reference to the version_number (Figure 21) of APT (Program_Association_Table), CAT (Conditional_Access_Table), NIT (Network_Information_Table), BIT (Broadcaster Information Table), SDT (Service_Description_Table), EIT (Event_Information_Table), additional when in this value, changing.

(c) SQH_Change: the sequence header information (Figure 22) in the MPEG2 data stream in the reference number broadcast data stream, additional when it changes.

(d) Data_Top: when the dsmccMeddageHeader () that detects in the DII (DownloadInfoIndication) in the digital broadcast data stream additional (Figure 23) time.

(e) Data_Change:, additional when in this value, changing with reference to the transaction_id (Figure 24) among the dsmccMeddageHeaderntr () among the DII in digital broadcast data stream.

(f) PMT_Change:, additional when in this value, changing with reference to the version_number (Figure 25) among the PMT (Program_Map_Table) in digital broadcast data stream.

(g) DE_Change:, additional when in this value, changing with reference to the data_event_id (Figure 26) among the DownloadID in the DII message in digital broadcast data stream.

(h) Module_Change:, additional when in this value, changing with reference to the module_version (Figure 27) in the DII message in digital broadcast data stream.

(i) Aud_Change: in component_type in the sound componential description symbol among the EIT of reference in digital broadcast data stream and the symbol of the sound componential description among the EIT _ sampling_rate (Figure 28), additional when in this value, changing.

(j) Multi_View: divide into groups to record and narrate the num_of_group (Figure 29) in the symbol with reference to the one-tenth among the EIT in digital broadcast data stream, additional when in this value, changing.

(k) father and mother's control information: the father and mother that private_data_byte during record accords with reference to the qualification receive mode among the PMT in digital broadcast data flows or the father and mother among the EIT (Event_Information_Table) control the rating symbols in the speed record symbol control rate information (Figure 30), add.

Once more with reference to Figure 19, resolution unit 1906 when detecting the content change of MPEG transmitting data stream, sends to system control unit 1902 (step S195) with at this moment time information as inlet point information with these detection information.It is the inlet point table of inlet point ensemble of communication that system control unit 1902 makes.

The requirement that stops according to from the user indicates whether to finish video (step S196).To require to send to system control unit 1902 from user's the video that stops through user interface section 1901, system control unit 1902 sends to digital tuner 1905 and resolution unit 1906 and stops requirement.When not from the stopping video and require of user, repeat the processing that begins from step S192, intactly continue video.

Resolution unit 1906 is accepted to stop to resolve requirement from system control unit 1902; Stop dissection process, last demonstration finish time (D_VOB_V_E_PTM) of the animate object unit (VOBU) of the MPEG transmitting data stream of resolving is at last sent to system control unit 1902.

System control unit 1902 is after the accepting processing and finish of digital broadcasting, and the information according to accepting from resolution unit 1906 generates digital broadcasting object information (D_VOBI), secondly, generates and this digital broadcasting object information (D_VOBI) corresponding cells information.At this moment, set " D_VOB " as the type information in the unit information.At this moment, system control unit 1902 generates inlet point table (step S197) from the inlet point information of accepting from resolution unit 1906.Again, at this moment, system control unit 1902 is according to the scene type (View Type) of the unit of inlet point information setting record.

Final system control module 1902 to driver 1911, sends the data recording that finishes to be stored in the trace buffer 1910 and the requirement of recording digital broadcast object information and unit information.Driver 1911 is recorded in remaining data, digital broadcasting object information (D_VOBI) and the unit information of trace buffer 1910 in the DVD-RAM CD 100, finishes video and handles (step S198).

When the requirement from the user is when analog broadcasting is recorded, also carry out same basically processing.But, be different so VOBU generates this point by equipment because 1904 pairs of transmitting data streams of coding unit are encoded.

When the requirement from the user is record data stream, carry out same basically processing.But, be different so each time information is set this point according to ATS because do not carry out the parsing of data stream object (SOB).

More than, we have explained the work of carrying out according to the requirement of recording from user's beginning and end.But for example when the timer that carries out also in existing VTR, using video, just replacing the user, system control unit automatically send beginning and finish video to require this point be different, the work of DVD registering instrument 1900 is identical in essence.

Below, we are with reference to Figure 31, and the work when requirement from the user is the data of regenerative recording in DVD-RAM is described.Figure 31 is the flow diagram of the Regeneration Treatment of expression DVD registering instrument 1900 (Figure 18).Below, we explain the situation of regeneration by the original PGC of 1 animate object (D_VOB) and 1 unit information formation.In addition, about the reproduction operation of following explanation, also can realize the identical work of DVD phonograph 1700 (Figure 17) with the front.

At first, user interface section 1901 acceptance are from the regeneration requirement of user's original PGC.User interface section 1901 will send system control unit 1902 from user's requirement to, and system control unit 1902 will be interpreted as the regeneration requirement of original PGC from user's requirement, and send processing requirements to each module.System control unit 1902 is resolved (Fig. 7) such as original PGC information 50 (Fig. 7) and unit informations 60, the specific object that will regenerate (step S311).That is, system control unit 1902 at first, is resolved the type information in the unit information in the PGC information.When type information was " D_VOB ", the AV data stream of judging regeneration was the AV data stream as MPEG transmitting data stream record.Secondly, system control unit 1902 is sought the digital broadcasting object information (D_VOBI) (step S312) from the correspondence of unit information ID from table (D_AVFIT).After this, system control unit 1902 is according to the information zero hour (M_VOB_V_S_PTM) and the information finish time (M_VOB_V_E_PTM) and the time diagram of animate object, the position of specific object in DVD-RAM (step S313).When the position of special object, system control unit 1902 is according to beginning and the end position information and the time diagram of unit information, tries to achieve the start and end address (step S314) among the DVD-RAM of AV data of regeneration.

When obtaining the address that will insert, system control unit 1902 will send to driver 1911 with reading the address from the requirement of reading of DVD-RAM CD 100.Driver 1911 is read the AV data from the address of system control unit 1902 indications, is stored in (step S315) in the trace buffer 1910.1902 pairs of demoders 1908 of system control unit send decoding request.Demoder 1908 is read the AV data in being stored in the trace buffer 1910, carries out decoding processing.Through the AV data (step S316) of display device 1907 outputs through decoding.

Driver 1911 judges from the reading of total data of system control unit 1902 indications whether finish (step S317).When not finishing, repeat the processing that begins from step S315, continue to read the AV data, when finishing, driver 1911 is read end to system control unit 1902 reports, and system control unit 1902 sends to demoder 1908 and finishes the regeneration requirement.Demoder 1908 carries out data reproduction till trace buffer 1910 becomes sky, becomes empty in trace buffer 1910, after the decoding and regeneration ending of all data, to system control unit 1902 report regeneration endings, finishes Regeneration Treatment.

More than, we are that example is illustrated with the original PGC by 1 digital broadcasting object (D_VOB) and 1 unit information formation.But, when original PGC only comprises 1 animate object (M_VOB), when comprising a plurality of animate object, when comprising a plurality of digital broadcasting object, perhaps, when animate object mixes with digital broadcasting object, also can be through carrying out same processing, reproducing AV data stream.Comprise the situation of a plurality of unit and also be same in the situation of user definition PGC at original PGC again.

Secondly, we do not have the regeneration function of whole AV data stream with demoder 1908 situation is an example declarative data flow object (SOB).Once more with reference to Figure 18, for example, when demoder 1908 does not have the regeneration function of MPEG transmitting data stream, as stated, can not stream of regenerated data through demoder 1908.Therefore, at this moment, data are supplied with external unit, carry out data reproduction in the external apparatus through digital interface unit 1909.

System control unit 1902; When the unit information in the PGC information that the regeneration that detects from the user requires is the unsupported data stream object of system (SOB); Replacement is sent the requirement that data is outputed to the outside to the regeneration requirement of demoder 1908 to digital interface unit 1909.Digital interface unit 1909 according to be stored in trace buffer 1910 in the communication protocol of the digital interface that is connected of AV data carry out data and transmit.In addition, except above-mentioned processing, identical when regenerating with digital broadcasting object (D_VOB).Both can self judge whether demoder 1908 is corresponding with the AV data stream of regeneration object by system control unit 1902, also can be from system control unit 1902 to demoder 1908 inquiries.Demoder 1908 oneself judges whether corresponding with this data stream with reference to the PSI/SI information of MPEG transmitting data stream.

We should note about data stream object (SOB), also exist can not resolution data stream content, the situation that a part of regeneration function is restricted.Particularly so-called special reproduction, for example regeneration slowly is because need the data flow data that repetition can regenerate separately and send, so will in the SOB of content that can not the resolution data flow data, realize it being difficult.

Therefore, according to the registering instrument 1900 of this example, when receiving the indication of this special reproduction from the user, with reference to the type information of this unit, if it is SOB, the message informing user I/F unit 1901 of the special reproduction that then can not indicate.

Again; Because consider above-mentioned restriction to data flow object (SOB) regeneration; So when making the PGC of the regeneration order of specifying a series of AV data stream, also can forbidden data flow object (SOB) and other object be digital broadcasting object (D_VOB) and animate object (M_VOB) and be blended in 1 PGE.

Below, we are to the CD of record AV data stream, and the processing when existence requires from user's inlet point setting be described.Figure 32 is the flow diagram that the setting of expression user inlet point is handled.When passing through user I/F unit 1901 (Figure 18); Existence is set (step S321) when requiring from user's inlet point; System control unit 1902 (Figure 18) is read the inlet point table from CD, on user I/F unit 1901, demonstrates the whole inlet points of the inlet point table in this unit and the attribute information (step S322) of setting.Here so-called inlet point table refers to the inlet point table of automatic setting shown in Figure 15 and the inlet point table that the user sets.That is the inlet point table 80d of the inlet point table 72 of the unit information 71 of user-defined PGC information 70 (Fig. 7) and object information 80 (Fig. 7)., also can be the inlet point table that the user sets.When not needing attribute information especially, can not show again, yet.

In addition; Attribute information is; For example, expression as the PG_Change of program variation point, expression as the PSI_SI of the variation point of the PSI/SI information in transmitting data stream, in the expression change transmitting data stream mpeg data stream attribute SQH_Change, expression data carousel formula tape the place, front Data_Top, expression data carousel formula tape content alteration point Data_Change, expression PMT variation point PMT_Change, expression data event renewal point DE_Change, representation module renewal point Module_Change, represent to change each flag information of the Aud_Change of voice attribute, for corresponding Multi_View symbols and the father and mother's control information of representing the scene number of program with many scenes.

Whole inlet points and attribute information according to showing carry out when the user needs from the regeneration of this point, can easily find get into desired program the position of the sight of wanting and desired data broadcast program, desired many scenes sight.

The user specifies expression to select the mark (step S323) of inlet point to registering instrument 1900.The system control unit 1902 of registering instrument 1900 when the mark indication accepted from the user inlet point, appends inlet point (step S324) in the inlet point table that the user sets.At this moment, the user when on the position beyond the original inlet point, not setting inlet point, specifies the starting position and the end position of the partial section of the data stream of hoping setting.The system control unit 1902 of registering instrument 1900, the information according to the starting position of accepting obtains and this starting position moment corresponding information PTS.System control unit 1902 appends inlet point in the inlet point table that the user sets, the time information PTS that obtains is registered among the time information EP_PTM.In addition, when the inlet point table (Figure 15) that is not provided with 2 types, during the inlet point set with the inlet point and the user of 1 table management automatic setting, when promptly utilizing the inlet point table of Figure 14, the USER_EP that sets the inlet point table indicates.

When accomplishing the setting of inlet point, end process (step S324).When not accomplishing, repeat the processing that begins from step S322, show the whole inlet points so far set and the attribute information of setting.

Secondly, we explain the Regeneration Treatment of inlet point with reference to Figure 33.Figure 33 is the flow diagram of the Regeneration Treatment of expression user inlet point.System control unit 1902 when the regeneration of accepting inlet point from the user requires (step S331), is judged the inlet point table on CD, whether exist the user to set (that is, inlet point table 72, perhaps, the table of the hypomere of Figure 15) (step S332).When the inlet point table that exists the user to set, read this table and be stored in the storage area that is used for showing, show inlet point (step S334).The trouble that the user can avoid showing a plurality of inlet points of oneself not recognizing is only selected the regeneration starting point from the inlet point of needs.When the inlet point table that do not exist the user to set, read the inlet point table of automatic setting, be stored in the storage area that is used for showing, show inlet point (step S334).In addition, best when utilizing the inlet point table of Figure 14, about each inlet point,, only read the inlet point of setting with reference to whether having set the USER_EP sign.

When the user selects inlet point, the information (step S335) of system control unit 1902 regioselective inlet point of 1901 acceptance from user I/F unit.System control unit 1902 detects inlet point inlet point moment corresponding information table and suitable EP_PTM (step S336).Precision at the time information of each inlet point of inlet point table is the 27Muz that uses among the common MPEG.In addition, also can make it is the value of following figure place bit of omitting frame number and the 90KHz or the 27MHz of video.

Further, use the object (D_VOB) corresponding, be arranged on the time diagram in the object information, time information is transformed into the fragment position information (step S337) on the CD with system control unit 1902.The MPEG transmitting data stream (step S338) of system control unit 1902 from this fragment position regeneration CD.

So, can be from inlet point reproduced picture and sound as the desired sight of user.At this moment the scene type (View Type) in the system control unit 1902 reference unit information, if its value beyond the expression 0, promptly many scenes are then with the scene type in the unit information (View Type) notice user interface section 1901.According to the scene type of notice, DVD registering instrument 1900 can be on the picture of user interface section 1901, and the scene number that for example demonstrates many scenes is as OSD (On Screen Display (showing on the screen)) information.

In Figure 32, Figure 33 and the explanation related, the demonstration of whole inlet points has been described with them.But, also can not necessarily show whole inlet points.For example, also can be only the inlet point of attribute change that data representing decide selectively, also can be only selectively demonstration be present in the inlet point of fixing time and being with.This selection can be according to the attribute information that is arranged in the inlet point table, and perhaps time information (EP_PTM) carries out.

In addition, in the regeneration of DVD registering instrument, when the unsupported AV data stream of regeneration demoder, regenerate through digital interface.But, even if the AV data stream that demoder is supported also can output to the external unit of the box that is arranged on the top etc. according to user's requirement through digital interface.

Again, the present invention has explained CD, optical disc recorder and compact disk audio player, even if but in other medium of for example hard disk etc. the situation of record MPEG transmitting data stream, through with same inscape, carry out same processing, also can access same effect.Therefore, in essence to not restriction of physical medium.At this moment but " same inscape " also can be taken on by central calculation element (CPU) and the image processing IC of for example PC.Bases such as CPU at this moment are by (logging program that can implement of the computing machine of the processing of Figure 19, Figure 31～Figure 33) carries out work according to above-mentioned flow diagram.This program itself is recorded in the various recording mediums of floppy disk, CD, semiconductor storage etc., and perhaps the communication line through the Internet etc. transmits, and is installed among the PC.

In this example, we have explained with the situation of MPEG transmitting data stream as the own coding data stream.But, both can use the MPEG program data stream, again, also can be data stream according to other form.

More than, we have explained the present invention about the example of certain illustrated.If the practitioner then understands certainly and can carry out many different changes and improvement.So above-mentioned example does not limit the scope of the present invention by additional claims regulation.

If according to carrier of the present invention, then can be with other AV data stream, the transmitting data stream that record is brought with digital broadcast transmitting, further, can discern for the inlet point of the digital broadcasting object that writes down is the inlet point that the user sets.Again; In each inlet point information in the inlet point table; Expression is set as the sign of program variation point, expression symbols, father and mother's control information symbols as the scene number of the flag information of the sign in the place of the sign in the place of the variation of the sign in the place of the sign in the place of the content of the sign in the place, front of the sign of the attribute of the sign of the variation point of PSI/SI information, expression change mpeg data stream, expression data carousel formula tape, expression change data carousel formula tape, expression change PMT content, representation module, expression change data event, expression change voice attribute and expression program; Through showing them, the user can easily find desired sight from these information.When the unit is when being made up of many scenes, can represent them to the user again.
