In the figure, solid arrows between blocks indicate data buses, and broken arrows indicate control buses.

In the optical disk device shown in FIG. 1, when the power is turned on, the system ROM and RAM
The system CPU unit 50 reads out the initial operation program from 52 and operates the desk drive unit 30. Therefore, the disk drive unit 30 starts the read operation from the lead-in area 27, and the volume management information area 74 of the volume management area 70 following the lead-in area 27.
Volume management information is read from. That is, the system CPU section 50 gives a read command to the disk drive section 30 in order to read the volume management information from the volume management information area 74 recorded at a predetermined position of the disk 10 set in the disk drive section 30.
The contents of the volume management information are read out and temporarily stored in the data RAM unit 56 via the system processor unit 54. The system CPU unit 50 extracts information such as the recording position and recording capacity of each file and other information necessary for management from the data string of the volume management information stored in the data RAM unit 56, and stores the information in a predetermined area of the system ROM & RAM unit 52. Transfer to a location and save.

Next, the system CPU section 50 refers to the information of the recording position and the recording capacity of each file previously acquired from the system ROM & RAM section 52, and the file number 0
The disk information file 76 corresponding to the number is acquired. That is, the system CPU unit 50 includes a system ROM and R
The AM unit 52 gives a read command to the disk drive unit 30 by referring to the information on the recording position and the recording capacity of each file acquired earlier, and outputs the file management information of the disk information file 76 having the file number 0. The data RAM section 56 is read through the system processor section 54.
To be stored. Similarly, the acquired information is used for system ROM &
It is transferred to a predetermined location in the RAM section 52 and saved.

The system CPU section 50 uses the disk configuration information 8 of the file management information of the disk information file 76.

The cell information to be reproduced first is acquired from the cell reproduction order information in the sequence information thus acquired, and the disk drive unit 30 is based on the video data reproduction start address and size in the cell information. Is given a read instruction from the target address. The disc drive unit 30 drives the optical disc 10 in accordance with the read command, reads the data of the target address from the optical disc 10, and sends it to the system processor unit 54. The system processor unit 54 temporarily stores the transmitted data in the data RAM unit 56, and determines the type of the data (video, audio, sub-picture, reproduction information, etc.) based on the header information added to the data. Then, the data is transferred to the decoder units 58, 60, 62 according to the determined type.

Each of the decoder units 58, 60 and 62 decodes the data according to their respective data formats, and D
/ A & sends to reproduction processing unit 64. D / A & reproduction processing unit 64
Converts the decoded digital signal into an analog signal, performs mixing processing, and outputs the mixed signal to the monitor unit 6 and the speaker unit 8.

In the process of determining the type of data, if the data is reproduction information indicating the reproduction position of the video data, this reproduction information is not transferred to the decoder, and this reproduction data is stored in the data RAM section. 56. The reproduction information is referred to by the system CPU unit 50 as necessary and used for monitoring when reproducing the video data.

When the reproduction of one cell is completed, the cell information to be reproduced next is obtained from the cell reproduction order information in the sequence information, and the reproduction is continued in the same manner.

By appropriately setting the description of PGC_CAT described in No. 05 by the program provider, it is possible to produce a title set having an excellent user interface in an interactive environment. That is, not only the simple serial reproduction mode in which the program chains are reproduced in ascending order from the entry program chain # 1 as shown in FIG. 87 (a), but also the program from the entry program # 1 as shown in FIG. 87 (b) is executed. Chain # 2, # 3, # 4
It is also possible to realize a branch reproduction mode in which the story branches to either of the two and the story progresses.

In the initial version format,
20 to 25, the method of creating a sequence is described. A program chain is created in the same manner as this description. In the description of FIG. 20 to FIG. 25, the sequence should be replaced with a program chain, a cell including an intercell command required when arranging cells should be arranged, and a pre-navigation command and a post-navigation command should be appropriately arranged to create a program chain. Good. Needless to say, it can be understood by referring to the description of the format according to the improved version and the description of FIGS. 20 to 25.

Next, referring to FIGS. 88 to 93, FIG.
From now on, a description will be given of video data in a logical format shown in FIG. 79, a recording method on the optical disc 10 for reproducing the video data, and a recording system to which the recording method is applied.

FIG. 88 shows an encoder system for generating a video file 88 of a title set 84 in which video data is encoded. In the system shown in FIG. 88, as sources of main video data, audio data, and sub-video data, for example, a video tape recorder (VTR) 201, an audio tape recorder (ATR) 202, and a sub-picture playback device (Subpicture, sour).

It is stored in the memory 216 by 205.

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

The main video data and audio data are encoded according to the flow shown in FIG. 89 and encoded main video and audio data (Comp, Video, Comp,
Audio) data is created. That is, when the encoding process is started, parameters required for encoding the main video data and audio data are set as shown in step 70 of FIG. Some of these configured parameters are system controller (Sys, con)
The file formatter (F
FMT) 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. As shown in step S272, 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,
Partial re-encoding of the main video data is performed, and the main video data in the re-encoded part is replaced. 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 (3) 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. 90, the encoded main video data, audio data, and sub-video data (Com, Video, Comp, Audio, Comp, Sub-pict) are combined to obtain FIGS. It is converted into the title set structure of the video data as described with reference to FIG. That is, as shown in step S276, a cell is set as the minimum unit of video data, and cell reproduction information (C_PBI) regarding the cell is created. Next, step S277.
As shown in, the configuration of cells constituting the program chain, main video, sub-video, audio attributes, etc. are set (part of these attribute information uses information obtained at each data encoding), As shown in FIG. 50, video title set information management table information (VTSI_MAT) 27 including information about program chains 27
8 and the video title set program chain table (VTS_PGCIT) 300 are created. At this time, a video title set direct access pointer table (VTS_DAPT) is also created if necessary. Encoded main video data, audio data, and sub video data (Com, Video, Comp, Audio, Com
