According to the description of the start address (NSML_AGL_C_DSTA) of such an angle cell,
Specifically, the following angle changes are realized.
Here, the angle change will be described on the assumption that a series of times from the pitcher's throw to the batter's hit and the hit to the home run are continuous in a baseball game.
Here, the angle cell (ANG_C # j) controlled by the PCI 113 can be changed in units of the video object unit (VOBU) 85 as shown in FIG. In FIG. 48, the video object unit (VOBU) 85 is numbered according to the playback order, but a certain angle cell (ANG_C

4, a full view of the pitcher and batter is displayed on the screen, and VOBUs 85 are continuously arranged as video data showing a series of motions. Also, the angle cell (ANG_C # 1) 84 is hit by the batter. In order to view the form, the VOBU 85 is continuously arranged as video data in which only the batter is projected on the screen, and further, in the angle cell (ANG_C # 9), only the facial expression of the pitcher is projected on the screen as V data.
It is assumed that the OBUs 85 are arranged in series. First, if the user changes the angle cell # 1 (AGL_C # j) to the angle cell # 1 at the moment when the user is watching it and hits it,
That is, if you change the angle to the angle that only the batter appears at the moment you hit, the screen will not change to the screen of only the batter after hitting, but the screen after the batter before the hit begins to swing the bat. Becomes In addition, if the angle cell #j (AGL_C # i) was first viewed and then changed to the angle cell # 9 at the moment of hitting, that is, if the angle was changed to an angle at which only the pitcher was projected, then the angle was hit. The momentary struck expression of the pitcher is displayed on the screen, allowing you to appreciate the psychological changes of the pitcher.

As shown in 0, the DSI general information (DSI_GI) includes
System time reference reference value of NV pack 86 (NV_PC
K_SCR) is described. The system time reference value (NV_PCK_SCR) is stored in the system time clock (STC) incorporated in each unit shown in FIG. 1, and the video, audio and sub-picture packs are stored as video, audio and sub-picture on the basis of this STC. The video and audio are decoded by the decoder units 58, 60 and 62, and reproduced on the monitor unit 6 and the speaker unit 8. In the DSI general information (DSI_GI), the start of the NV pack (NV_PCK) 86 in which the DSI 115 is recorded with the relative logical sector number (RLSN) from the first logical sector of the VOB set (VOBS) 82 in which the DSI 115 is recorded. Address (NV_PCK_LBN) is described and VO

It is described in (SML_AGLI).

DSI angle information (SML_AGL
When I) is used, the PCI can be changed in the video object unit (VOBU), but the angle is changed in cell units, and the scene is continuously changed in time. That is, the PSI angle information (SML_AGL
I) describes a temporally discontinuous angle change, whereas the DSI angle information (SML_AGLI) describes a temporally continuous angle change. If the concrete example of the angle is explained using the above-mentioned baseball example, the following change of the angle is realized. The angle cell #j (AGL_C # j) 84 is a stream of image data in which the pitcher throws the ball, the batter hits the ball, and a series of scenes in which the ball hits the home run is captured from the infield side. Let us assume that a similar scene is an image data stream captured from the outfield side. In addition, it is assumed that the angle cell # 9 is an image data stream obtained by photographing the state of the team to which the batter belongs in the same scene. If angle cell #j (AGL_C # j) is viewed and changed to angle cell # 1 at the moment of hitting, that is, if the scene from the outfield side is changed at the moment of hitting, it will be continuous in time after the batter's hit. You can change to a screen where a hit ball flies to the outfield. In addition, if you change to angle cell # 9 at the moment when you are watching the angle cell #j (AGL_C # i) and start a home run, that is, if you change the angle to show the situation of the team to which the batter belongs, you will get a home run. The state of the team and the facial expression of the manager who were in a fuss are displayed on the screen. Thus, the PCI 113 angle information (NSML_AGL
I) and angle information of DSI115 (SML_AGL
When I) is used, a clearly different scene will be reproduced.

As shown in step S23, it is checked whether the angle is changed. The angle can be changed from the key operation / display unit 4 or the remote controller 5 to the system C.
It is determined based on whether the PU unit 50 has an input for changing the angle. If the angle is not changed, it is checked whether the cell 84 is the last cell of the program chain (PGC) to which the cell 84 belongs, as shown in step S24. This check is judged depending on whether the cell 84 shown in FIGS. 27 and 33 is the last cell of the cell reproduction information table (C_PBIT) 107. That is, it is checked by the number of cells constituting the program chain and the identification number of the reproduced cell. If the cell does not correspond to the last cell of the program chain (PGC), the process returns to step S19 again.

Cell 84 is a program chain (PGC)
If the cell is the last cell of, the next program chain (PGC) is designated as the end of the program chain. Except in special cases, the program chains are played back in numerical order, so step S25
As shown in (1), the program chain number to be reproduced next is set by adding 1 to the number of the program chain which has been reproduced. In step S26, it is checked whether or not there is a program chain with the set program chain number. If there is no program chain to be reproduced next, the flow proceeds to the procedure of the reproduction end procedure shown in FIG. 65 described later. If there is a set program chain, the address of the cell of the reset program chain as shown in step S27, that is, the cell playback information (C_PB shown in FIG. 34.

If it matches the system time clock (STC), the display of the screen of the monitor 6 is stopped as shown in step S32, and the system CPU is displayed as shown in step S33.
Then, a data transfer stop command is given to the disk drive unit 30, the data transfer is stopped, and the reproducing operation is ended.

When an angle change is input from the key operation / display unit 4 or the remote controller 5 in step S23, it is checked whether or not there is angle data as shown in step S40 of FIG. The presence or absence of this angle is determined by the PCI data 1 of the navigation pack 86.
It is described as angle information (NSULS-ANGLI, SML_AGLI) in both 13 and DSI data 115. Here, any information is checked by the system CPU unit 50 in response to an input from the key operation / display unit 4 or the remote controller 5. If there is no angle to be changed in step 40, the fact that there is no angle data is displayed on the key operation / display unit 4 or the monitor unit 6 as shown in step S41. After the display without this angle data,
Control goes to step S24. If there is angle data, the angle number to be changed is specified from the key operation / display unit 4 or the remote controller 5 as shown in step S42. Here, as described above, the angle information (NSU) of PCI data and DSI data is
Which of LS-AGL_CI and SML_AGLI is used to change the angle is designated. However, when there is only one angle information, the selection is limited to one. When the angle number is specified, the target address (NSLS_A) of the angle cell corresponding to the specified angle number as shown in FIGS. 47 and 48.
GL_C_DSTA, SML_ANG_DSTA) are obtained in step S43. A cell is searched at this address, and the address is set as the logical block number (NOWLBN) to seek. Here, especially PCI
At the time of changing the angle using, the system CPU unit 50 performs the mute process for the reproduction of the video and audio data and the pause process for the reproduction of the sub-picture in accordance with the angle changing operation. Along with this processing, the system time clock (STC) of each part of the playback device is stopped, and the buffers in the video, audio and sub-picture decoder parts 58, 60 and 62 have already been cleared, and changed angle data can be accepted. The state is set (step S44). At the same time, as shown in step S45, the system CPU section 50 issues a read end address command to cause the disk drive section 30 to temporarily stop the read operation. After that, as shown in step S46, a read command is given from the system CPU section 50 to the disk drive section 30, and the cell is searched and selected by the set logical block number to seek, that is, the start address of the selected angle cell. The transfer of angle cell data is started.

When the transfer is started, the transfer of the navigation pack of the first cell, which is the change angle destination, is again waited. As shown in step S48, it is checked whether or not the transfer of the navigation pack due to the data transfer is completed, and if the transfer of the navigation pack is not completed, the process returns to step S47 again. When the navigation pack 86 is transferred, each system time clock (STC) is set by referring to the SCR (NV_PCK_SCR) of the NV pack 86 described in the DSI general information (DSIG) of the navigation pack 86. Then, the mute state of the video and audio and the pause state of the sub-picture set in step S44 are released,
The operation of the system time clock (STC) is started. After that, step S21 shown in FIG. 63 is executed similarly to the normal reproduction.

It is stored in the memories 210, 211 and 212 as pict.

The main video data, audio data, and sub video data (Comp Video, Comp Audio, Comp Sub-pic
t) is output to the file formatter (FFMT) 214 by the system controller (Sys con) 205, converted into the file structure of the video data of this system as described above, and the setting conditions and attributes of each data, and the menu. Management information such as data for creating data is stored in the memory 216 as a file by the system controller (Sys con) 205.

The data for creating this menu data is the number of parts of title (PTT_N
s), the number of title search pointers (TT_Ns), the number of audio streams (VTS_AST_Ns), the number of sub-picture streams (VTS_SPST_Ns), the audio stream attribute (VTS_AST_ATR), the sub-picture stream attribute (VTS_SPST_ATR).

The standard flow of the encoding process in the system controller (Sys con) 205 for creating a file from video data will be described below.

According to the flow shown in FIG. 68, main video data and audio data are encoded and encoded main video and audio data (Comp Video, Comp Aud
io) data is created. That is, when the encoding process is started, parameters required for encoding the main video data and the audio data are set as shown in step S270 of FIG. Some of these set parameters are system controller (Sys con) 2
File formatter (FF
MT) 214. As shown in step S271, the main video data is pre-encoded using the parameters, and the optimal distribution of the code amount is calculated. Step S
As shown by 272, the main video is encoded based on the code amount distribution obtained by the pre-encoding. At this time, audio data encoding is also executed at the same time. If necessary as shown in step S273, the main video data is partially re-encoded to replace the re-encoded main video data. Main video data and audio data are encoded by this series of steps. Further, as shown in steps S274 and S275, the sub-picture data is encoded and encoded sub-picture data (Comp Sub-pict) is created. That is, the parameters necessary for encoding the sub-picture data are similarly set. Step S274
A part of the parameters set as shown in (1) is stored in the system controller (Sys con) 205 and used by the file formatter (FFMT) 214. The sub-picture data is encoded based on this parameter. By this processing, the sub-picture data is encoded.

According to the flow shown in FIG. 69, the main video data, the audio data, and the sub video data (Com Video, Comp Audio, Comp Sub-pict) encoded are combined and the video as described with reference to FIG. Converted to data title set structure. That is, step S27
As shown in 6, a cell is set as the minimum unit of video data, and cell reproduction information (C_PBI) regarding the cell is created. Next, as shown in step S277, the configuration of cells constituting the program chain, main video, sub-video, audio attributes, etc. are set (some of these attribute information are obtained by the information obtained at each data encoding. 12, the video title set information management table information (VTSI_MAT) and the video title set time search map table (VTS_MAPT) 142 including the information about the program chain are created. At this time, a video title set part of title search access pointer table (VTS_PTT_SRPT) is also created if necessary. Encoded main video data, audio data, and sub video data (Com Video, Comp Audio, Comp Sub-pict) are subdivided into fixed packs, and each VOBU unit can be played back in order of the time code of each data. Each data cell is arranged while arranging the NV pack at the head thereof to form a video object (VOB) composed of a plurality of cells as shown in FIG. 6, and the set of the video objects is formatted into a title set structure. To be done.

In the flow shown in FIG. 69, the program chain information uses the database of the system controller (Sys con) 205 in the process of step S277, or re-enters data as necessary. Is executed and is described as program chain information (PGI).

FIG. 70 shows a disc formatter system for recording a title set formatted as described above on an optical disc. As shown in FIG. 70, in the disk formatter system, these file data are stored in the memories 220 and 222 in which the created title set is stored, and the file formatter
MT) 226. In the volume formatter (VFMT) 226, the management information is extracted from the title sets 84 and 86 to create the video manager 71, and the logical data to be recorded on the optical disc 10 is created in the arrangement order shown in FIG. Data for error correction is added to the logical data created by the volume formatter (VFMT) 226 in the disk formatter (DF).
MT) 228 and reconverted into physical data to be recorded on the disc. Modulator 230
At, the physical data created by the disk formatter (DFMT) 228 is converted into the recording data to be actually recorded on the disk, and the modulated recording data is recorded on the disk 10 by the recorder (Recoder) 232.

A standard flow for creating the above-mentioned disc will be described with reference to FIGS. 71 and 72. Figure 7
1 shows a flow in which logical data to be recorded on the disk 10 is created. That is, step S28
As indicated by 0, parameter data such as the number of video data files, the order of arrangement, the size of each video data file, etc. is set at the beginning. Next, from the parameters set as shown in step S281 and the video title set information 281 of each video title set 72, the video manager 7
1 is created. Then, as shown in step S282, the video manager 71 and the video title set 72 are displayed.
In this order, the data is arranged along the corresponding logical block number, and the logical data to be recorded on the disk 10 is created.

After that, a flow for creating physical data to be recorded on the disc as shown in FIG. 72 is executed. That is, as shown in step S283, the logical data is divided into a certain number of bytes, and error correction data is generated. Next, as shown in step S284, the logical data divided into a fixed number of bytes and the generated error correction data are combined to create a physical sector. afterwards,
As shown in step S285, physical data is created by combining the physical sectors. In this way, the physical data generated by the flow shown in FIG. 72 is subjected to a modulation process based on a certain rule to create recorded data. Then, this recording data is recorded on the disc 10.

The above-mentioned data structure can be applied not only to the case where it is recorded on a recording medium such as an optical disk and distributed to the user for reproduction, but also to a communication system as shown in FIG. That is, according to the procedure shown in FIG. 67 to FIG.
The optical disc 10 in which the video manager 71, the video title set 72, etc. are stored in the reproducing apparatus 300, the encoded data is digitally taken out from the system CPU section 50 of the reproducing apparatus, and the modulator / transmitter is used. It may be sent to the user or the cable subscriber side by radio wave or cable by 310. Also, data encoded on the provider side such as a broadcasting station is created by the encoding system 320 shown in FIGS. 67 and 70, and this encoded data is similarly generated by the modulator / transmitter 3.
It may be sent to the user or the cable subscriber side by radio wave or cable by 10. In such a communication system, the information of the video manager 71 is first modulated by the modulator / transmitter 310 or directly distributed to the user for free, and when the user becomes interested in the title, the user or subscriber can In response to the request from the user, the title set 72 is transmitted to the user side by the modulator / transmitter 310 via radio waves or a cable. In the transfer of the title, first, the video title set information 94 is sent under the control of the video manager 71, and thereafter, the video object 95 for the title in the video title set reproduced by the title set information 94 is transferred. At this time, if necessary, the video object 95 for the video title set menu is also sent. The transmitted data is received by the receiver / demodulator 400 on the user side, and is processed as encoded data by the system CPU unit 50 of the reproducing apparatus on the user or subscriber side shown in FIG. Is played.

In transferring the video title set 72, the video object sets 95 and 96 are transferred in units of the video object unit 85 shown in FIG. In this video object unit 85, an NV pack 86 in which video reproduction and search information is stored is arranged at the head thereof. Moreover, this NV pack 86
Since the address of the video object unit to be played back and forth based on the video object unit 85 to which the NV pack 86 belongs is written in the field, the video object unit 85 is transferred for some reason during the transfer of the video object unit 85. Even if the video data is missing, the video data can be surely reproduced on the user side by requesting the retransmission of the missing video object unit 85. Further, even if the transfer is not performed in the reproduction order of the video object unit, the system ROM / RAM unit 52 on the user side holds the reproduction information of the correct program chain, and the address data of the NV pack 86 is referred to for the reproduction order. Can be instructed by the system CPU unit 50.
