1T -25- A7 £ 7_ 5. Description of the Invention (23) The title_number in play_item () is used to specify a title. The time set by a title is used to determine the start and end points of taking out all the films. A plurality of these slices 1 are assembled to constitute a program. The following describes an additional recording operation to record new information on disc 1. Specifically, the additional recording operation is generally performed as a recording operation, or by a user. The input unit 14 is operated to input a command to perform real-time recording on the optical disc device. In the latter case, if the recording end time is unknown, press the record button ^ However, if the recording end time is predictable, press the one-touch recording function button. One-touch recording function is used to perform fixed-time recording. The additional recording operation is explained by taking timer recording as an example. In this case, the user of the optical disc device specifies a recording start time, a recording end time, a digital rate of a digital stream, and a channel to be recorded, etc. in advance. Moreover, at the time of recording reservation, check disc 1 in advance to determine whether there is free space left for the digital rate and recording time length. If another recording operation is performed on disc 1 between the scheduled time and the time when the scheduled recording is performed, it is highly likely that the free space for confirming that the scheduled recording is performed at the specified rate no longer exists. In this case, c P U 2 1 reduces the number rate to less than one of the previously specified, and records the data at the time of the appointment, or keeps the number rate unchanged, and records the information for as long as possible. Without a word, CPU 2 1 continues to perform the recording operation, and when it is detected that the scheduled recording is inconvenient, it sends a message to inform the user of the inconvenience. When the start time of the scheduled recording is approached, the CPU uses the embedded rule.

Description of the invention (24) (Yes " Please refer to the note below for further details) The clock and clock signal 'to automatically restore the disc device from sleep mode to operation mode . Then, the CPU 21 sends out the file system operation 1 contained in the processing procedure 作 as an instruction to allocate an area 'for recording the reserved program on the optical disc 1. That is, first, the CPU 21 subtracts the start time from the end time of the reservation recording to obtain the recording time length, and then calculates the product of the recording time length and the bit rate to obtain the size of the area to be allocated for recording the reserved program. In addition to the digital stream files required to schedule recordings, data may need to be stored in information files. More specifically, when a new title needs to be stored in the title information file, an area needs to be allocated on disc 1 to record the title information file. If an area with a sufficient size cannot be allocated, the above-mentioned reverse Control technology, that is, to reduce the number of bits, or to perform the recording operation only at a time equivalent to the allocated area. It should be noted that since a new title is stored in this case, the user provides a name to the new digital stream file, and, strictly speaking, to the new digital stream file in the new digital stream directory. Suppose the name is ¥ MPEGAV ¥ STREAM_003 ¥ CHUNK_003 1. That is, the name of the digital stream file is CHUNK_003 1.MPEG2 in the STREAM_003 directory under the MPEGAV directory in the root directory shown in FIG. C P U 2 1 Issues an execution command to other components of the optical disc device in the recording mode. For example, a video signal v received via the input terminal P 3 and an audio signal from a tuner (not shown in the figure) through the input terminal P 4 are decoded by the decoder 10 and then stored in the write channel. In buffer 1 1.

At this time, the data to be recorded in the newly set file named CHUNK_003 1 .MPEG2 is read from the write channel buffer 1 1, via switch 5, ECC circuit 4, RF and demodulation / modulation power. In the above operation period, when one of the following events occurs, the CPU suspends the operation. 1. The end time of the scheduled recording is up. 2 • Information cannot be recorded on disc 1 due to, for example, insufficient storage capacity. 3. Receive an instruction to stop the recording operation. Secondly, by using the file system operation instructions contained in the processing program in advance, the CPU 2 1 points to one of the new record locations of information and more recently to the index of CHUNK_003.MPEG2 in the file system. In addition, the CPU 2 1 prepares each block information. For the archives of digital block group information and title information, give these files a name and record the information in the files. It should be noted that during the recording operation or at the reserved time, the free space for recording files needs to be allocated on disc 1 in advance. As a result, a new information file is generated, as shown generally in Figure 30. In the figure, each file with a star placed to its right is the newly created file in the above operation.

That is, the new digital stream is recorded in the information file as TITLE_004. By using a function of the optical disc device, it is confirmed that a title ' user can know information of attributes such as TITLE_004. Moreover, TITLE_004 can be played back. ○ The following describes the operation of overwriting / recording information on disc 1. It is the same as that shown in Fig. 26 (or Fig. 27). -It is similar to the operation of recording a signal on a video tape, and the overwrite-record operation is an operation to record a new program on an existing program that has been recorded on the disc 1, and obliterate the existing program. In an overwrite-record operation, where the operation starts is important. Assume that the user specifies that the beginning of TITLE_001 is the position at which to overwrite a record. In this case, by overwriting the existing information recorded in TITLE_001, TITLE_002, and TITLE_003 in the order listed, the overwriting-recording operation is performed. If the overwrite-record operation is not completed even when the end of TITLE_003 is reached, the recording operation is continued by allocating a new free area to disc 1. If TITLE_002 is specified as the position to start overwriting-recording, the information in TITLE_001 is not overwritten by the recording device, because TITLE_001 is before the operation start position. Assume that timer recording is performed by overwriting existing information, starting at the beginning of TITLE_003 \. In this case, the user of the optical disc device first specifies the recording start time, the recording end time, the number rate of the digital stream * and the channel to be recorded. Furthermore, the beginning of TITLE_003 is designated as the recording start position, which is important for overwriting a recording operation. • And, in this case, the home sample (CNsl (210X297 ^ ft) ~~ " -29- A7 ____ B7__ 5. Description of the invention (27) At the time of recording reservation, first confirm whether there is space on the disc 1 applicable to the digital rate and recording time. In the case of overwriting a recording operation, The total size of multiple rewritable titles and the sum of free areas on disc 1__ from the specified position are recordable space. More specifically, in this case, STREAM_0011 and STREAM_0012 The total size of the digital stream and the sum of the free areas are recordable spaces. In the overwrite-record operation, there are some items to choose from for the above recordable spaces and the order of the actual recordings to be performed. As the first conceivable selection item, one of the technologies of sequential digital stream record information can be selected to be specified in the title. To be more specific, in this case, a technology can be selected, wherein Start recording, and when the end of STREAM_0011 is reached, continue recording to the beginning of STREAM_001 2. Then, when the end of STREAM_0012 is reached, continue recording on the free space of disc 1. In another technique, first, the freedom of disc 1 Recording is performed on the area, and when the free area is used up, recording is continued on the existing digital stream. The former technology is superior because this technology imitates a videotape. That is, because the recording operation is similar to recording information on the videotape, Operation, so the feature of the operation is that the user can easily understand the operation. "On the other hand, it is characterized by the recorded digital stream being erased later. The latter technology is better at protecting the recorded information. If another recording operation is performed on disc 1 between the time when the appointment is set and the time when the scheduled recording is performed, it is very likely that it will be used to test the KK home purine in Jfl_ ((, NS) Λ4 Xianbai (210X297 mm) ---------- (For the precautions to read first, then "quote this page") -30-A7 _B7_ V. Description of the invention (28) The experience of performing scheduled recordings on the digital rate The free space is considered to be non-existent. In this case, much like the additional recording operation described earlier, the CPU 21 automatically reduces the number rate from _ 'to less than the specified one to record the information of the reservation time. Or record information for as long as possible, keeping the number rate unchanged. When the start time of the scheduled recording is approaching, the disc device returns from sleep mode to operation mode. CPU2 1 allocates all free areas on disc 1. No waiting Speakers also have a method, so that free zones are not allocated at this time, but are allocated when such a zone is needed. For simplicity of explanation, the required area is allocated before the recording starts. It should be noted that since the start time, end time, and number rate are specified, the size of the required area is known before the timer records, so it can only be allocated with the required size, or the required size plus some extra margin. region. However, in a case where an information file needs to be recorded, such as in a recording period, when a title information file needs to be recorded as a new title, an area having a sufficient size is allocated to record the information slot case. Provide a name for the new digital stream file. Strictly speaking, a new digital stream file in the New Digital Stream directory assumes that the name is ¥ MPEGAV ¥ STREAM_002 ¥ CHUNK_0031. That is, the name of the digital stream file is CHUNK_0031.MPEG2 in the \ STREAM_002 directory in the MPEGAV directory in the root directory shown in Figure 32. A video signal is received via input P 3 and an audio signal from a tuner (not shown) is received via input P 4 is decoded by decoder 10 and then stored in the write channel buffer器 11 1。 In the device.

Description of the Invention (29), CPU2 1 moves the optical head 2 to the address of the area allocated earlier. The writing position determined by the information. The CPU 2 1 then sets the optical head 2, the RF and the demodulation / modulation circuit 3, and the ECC circuit 4 in the write mode, and sets the switch 5 to one of the write channel buffers 1 1. After the position of the optical head 2 is finely adjusted, the writing operation of the optical head 2 is started. At this time, the read from the write channel buffer 11 is to be recorded in the newly set file named CHUNK_003 1.MPEG2 The data is recorded on the optical disc 1 via the switch 5, the ECC circuit 4, the RF and demodulation / modulation circuit 3, and the optical head 2.

1T At this time, first, rewrite the digital stream gun case named CHUNK_0011.MPEG2. After the recording has reached the end of the file named CHUNK_0011.MPEG2, the operation continues to the digital stream file named CHUNK_0012.MPEG2, and then continues to the digital stream file named CHUNK_0031.MPEG2. During the execution of the above processing, the CPU 2 1 stops the write operation at any point in time when any of the 3 conditions described earlier is met. Then, the CPU 21 executes a file system operation instruction included in the processing program in advance to update the digital stream file, digital block information, digital block group information, and title information. By the way, the configuration of the file changes synchronously with the completion of the write operation. For example, after completing the writing operation of the binary stream files named CHUNK_0011.MPEG2 and CHUNK_0012.MPEG2, the name of CHUNK_0031. When the digital stream file of MPEG2 is recorded, the configuration of the file on disc 1 is changed to that shown in Figure 33. The name of the file with a star attached to the right is the name of the newly generated file at this time. Κ 家 用 行 4 (210 X 297 mm) 纸 4 (210 X297 mm) -32- •-^ '' Μ A7 _B7__ 5. Description of the invention (30) Figure 3 4 shows so new The generated file is the relationship between the files shown in IB3 3. When compared with that shown in FIG. 31, it can be seen that CHUNK_0031 is added as a number block contained in CHUNKGROUP_002 specified by 'TITLE_003' and CHUNK_003 1 specifies STREAM_0031. On the other hand, if the overwrite-record operation is completed and the data is written into the existing digital stream file, that is, if the overwrite-record operation is completed, the data is written into the digital stream file named CHUNK_0011.MPEG2 , The free area allocated for the overwrite operation of the digital stream planting case named CHUNK_0031.MPEG2 is released because no data is overwritten on the file. In this case, special title processing is performed. In detail, when the overwrite-record operation starts at the beginning of TITLE_003 and the operation is completed in the middle, the title is divided. More specifically, as shown in FIG. 35, the new TITLE_003 is specified in an area between the start position and the completion position of the overwrite-record operation, and TITLE_004 is specified in the area after the area, that is, the area originally designated as TITLE_003 is assumed The rest of the area. Next, the playback of a title will be described. It is now assumed that a disc 1 having a file shown in FIG. 26 is inserted into the disc device, and then a title of the disc 1 is played back. When the optical disc 1 is inserted into the device, first, C P ϋ 21 reads out the data in the information file on the optical disc 1 and stores the data in the RAM unit 24. The reason here is to repeat the basic operation to read out the information in the information file described earlier.

More specifically, first, the CPU 21 reads out the data in VOLUME.TOC and ALBUM.STR. Then, CPU2 1 checks the directory named TITLE to find out how many extensions and VDs in this directory have trial papers ((.NS) Λ4 specifications (2 丨 OX297)) Order {read first And the precautions should work again?

The number of files is equal to the number of titles. In the example shown in Figure 26, the number of titles is three. Then, _'C PU 2 1 reads out the header information in the three files and stores the information in the RAM unit 2 4. The CPU 2 1 controls the OSD control circuit 9 so that the OSD control circuit 9 generates character information, that is, information of a title recorded on the optical disc 1. The character information is synthesized with the video signal by the synthesizing circuit 8. The synthesized result is then output through the output terminal P1, and is displayed on the display unit. More specifically, the length and attributes of 3 existing titles that are present in the scale are displayed. The attribute contains the title name, and the date of the title record. It is assumed that the user designates TITLE_002 as the title to be played back, for example. In the information file of TITLE_002, to be more specific, in the cgit_file_id of title_info () shown in FIG. 16, one of the specified HUNKGROUP_001 title I D »CPU2 1 is recorded in the file ID, and HUNKGROUP_001 is stored in the RAM unit 24. Then, the CPU checks CHUNK corresponding to the start and end time of TITLE_002. The start and end times are recorded in title_start_chunk_group_time_stamp and title_end_chunk_group_time_stamp of title_info () shown in Figure 16. The check is performed by comparison with the information contained in the information on a HUNKGROUP, whose individual blocks have been recorded. More specifically, the check is performed by comparing the information recorded in the presentation_start_cg_time_count and presentation_end_cg_time_count places of chunk_arrangement_info shown in Fig. 23 to the paper's recognition standard, which is the ten-decade_ (('N'S) Λ4 Regulations (210X297 public address)'- 34- A7 __B7__ V. Description of the Invention (32) {诮 Read the precautions on the back first and then copy this page). In this example, know that the start time of TITLE_002 is in the middle of CHUNK_0001, as shown in Figure 27. That is, obviously, in order to play back TITLE_〇d2 from the beginning, the playback operation needs to start from the middle of the CHUNK_0001.MPEG2 digital stream file. Thereafter, CPU 2 1 checks the digit stream to determine which part of the digit stream corresponds to the beginning of TIELE_002. That is, CPU2 1 calculates an offset time (a time stamp) in one of the number streams corresponding to the beginning of TITLE_002. Second, by using the characteristic point information in the CHtJNK file, a playback start point corresponding to a point immediately before the start time is identified. In this way, the offset distance between the playback start point and the beginning of the file can be determined. Then, using the file system operation instructions contained in the processing program beforehand, C P U 2 1 confirms that the physical address of CHUNK_0011.MPEG2 and its length have been recorded on disc 1. Moreover, the offset address of the playback start point found earlier is added to this physical address to finally confirm the address of the playback start point of TITLE_002. Thereafter, CPU2 1 moves the optical head 2 to the readout position determined by the information on the address of CHUNK-0001 .MPEG2 · CPU2 1 then sets the optical head 2, RF and demodulation / modulation circuit 3, and ECC The circuit 4 is in the read mode, and the switch 5 is placed in parallel with one of the read channel buffers 6. After the position of the optical head 2 is finely adjusted, the reading operation of the optical head 2 is started. At this time, the data read from the file named CHUNK_0001.MPEG2 is stored in the read channel buffer 6. The data stored in the readout channel buffer 6 is then output to the decoder 7, where it is decoded.

However, these etc. The file usually does not exist on the newly inserted disc. In this case, that is, when VOLUME_TOC and ALBUM.STR cannot be read, the CPU 21 sends a message requesting the user's instruction. In response to this message, Issued by the user For CPU2 1, if the newly inserted disc has a different format, eject the disc 1, or initialize the disc 1 if the newly inserted disc is a new disc with even the same format. Or, in the case of a disc with the same format In the case that the data on the disk is damaged, the instructions can restore the data on the newly inserted disc by using some methods. Second, further explain a title. TITLE _ ###. VDR shown in Figure 15 is a file for storing The information of a title. The information of a title \ title is recorded in a title_info () field.

CGIT is a file The title is used to store the definition of the time axis of a title contained in the title, the configuration of the digital block, and the processing of discontinuities. A title contains various digital streams, such as digital data without video data. Stream and DV (digital video) digital stream. In a DV format, a time axis is specified in frame units. If MP EG is used as the reference STC (system clock), the format is different, and a DV digital stream cannot be controlled To do this, set a local time axis in the title. The time axis is not related to the stream of digits that make up the title. Setting the boundary between titles has nothing to do with the boundary between digit blocks. Therefore, it is not necessary to set each digit The block uses a local time axis (that is, associated with a number of streams on a 1: 1 basis), or sets each standard The question uses a local time axis, but a local time axis is used to properly set a group of digital blocks that contain multiple titles, that is, titles with random numbers. A group of digital blocks is called a digital block group. In the block group, a single time axis is defined. On the time axis, each block is connected to determine the time for displaying each block. That is, a block group is arranged for each block. State, where a digit stream file (a row of digit tuples) is expanded along the time axis. In a digit stream file along the time axis

One arrangement of all the blocks of elements contained in V is called a path. In a number block group, multiple paths can be arranged. The path that specifies the playback start time and playback end time of a block group is called a main path. The other paths are secondary paths. A pair of paths mainly represents information such as audio digits, which are later recorded in a paper-based scale.

The connection points between the blocks need not coincide with the boundaries between the titles. Therefore, the connection points between the blocks are not a title. However, if the relationship between each number block is listed as a number block attribute, there is an opposition at the level of class organization. The information on this discontinuity point is placed between a number block and a title. It's considered to be appropriate to be placed at the hierarchical organization level of the digital block group. In the above, the information of the digital block group includes how to arrange each digital block along the time axis, and play back the sequence of each digital block. Sequence, a discontinuity at the connection point between the end of the first digit block and the start of the next digit block to be played back after the first digit block. It should be noted that a digit block group can also be used to Specify the digital stream to be played back at the same time. For example, in the example shown in Figure 38, TITLE_001 specifies HUNKGROUP_001, Specify CHUNK.0001 and CHUNK.0002. At least part of STREAM_0001 and STREAM_0002 specified by CHUNK_0001 and CHUNK_0002, respectively, overlap on the time axis, and therefore play back at the same time. Figure 3 9 shows a situation in which this one-tuple block group is generated. In this case, the digital block A that controls the digital stream A is combined with the digital block B that controls the digital stream B. In the resulting digital block group, the control digital blocks A and B are respectively the same as a main Path and a pair of paths. At least part of the digital streams A and B overlap each other and are therefore played back at the same time. "As shown in Figure 40 and Figure 21, the file_type_id of CHUNKGROUP _ ###.

Next, the title editing process is described to divide and move a title. In the title division operation, an existing title is divided at a position designated by the user to generate a new title. In a title moving operation, the order of the titles is changed. The format structure of one of the above title information files is a structure that can easily perform a title division operation and a title movement operation. That is, according to the above format, a group of digits, that is, a structure containing a collection of digit stream files, and a title, that is, a structure that is recognized by the user as a title can be divided into information pieces. And the operation of moving a title * does not need to change the information under a group of digits. "Second, referring to the flowchart shown in FIG. As shown in the figure, the process starts from step S1, where the user specifies a dividing point. For example, a predetermined position in TITLE_002 shown in FIG. 27 is designated as the dividing point. The processing flow then proceeds to step S2, where the CPU 21 makes a name TITLE_002. An information file of VDR, as the first title, has the title to be divided, that is, the start point of TITLE_002 before the division is its starting point, and the division point is its ending v point. Then, the processing flow proceeds to a step S 3, where the CPU 21 generates an information file named TITLE_003.VOR as a second title, with a division point as its starting point, and a paper size of the title book to be divided.

Description of the invention (45), that is, the termination point of TITLE_002 before division is used as its termination point. Thereafter, the processing flow proceeds to step S4, where the CPU changes the title of the title after the divided title. More specifically, TITLE_003 shown in FIG. 2 is changed to TITLE_004, resulting in the title shown in FIG. 4-9. As described above, the information on a digit block group, digit block, and digit stream does not change, even when a title is divided. Next, with reference to a flowchart shown in FIG. 50, the process of exchanging titles will be described. More specifically, -TITLE_002 shown in Fig. 49 is exchanged with TITLE_003 shown in the same figure. As shown in FIG. 50, the process starts from step S11. Here, the CPU 2 1 changes the name TITLE_002 of the title with the number 002 to TITLE ^ X with the title of one of the numbers X. The processing flow then proceeds to step S12, where the CPU 21 changes the name TITLE_003 of the title having the number 003 to TITLE_002 having the title of the number 002. Then, the processing flow proceeds to step S13, where CPU 2 1 changes the name of the title having the number X, and TITLE_X is TITLE_003 having the title of the number 0 0 3. As described above, CPU21 first changes the name of the title with the number 002 TITLE_002 to TITLE_X with one of the titles X, and then \ changes the name of the title with the number X TITLE_X to TITLE_003 with the title 0 0 3. It is avoided here that if CPU 2 1 directly changes the title of the title with the number 0 0 2 TITLE_002 to TITLE_003 with the title of the number 0 0 3, then the CPU 2 1 changes the scale of the paper with the number桠 彳 (CNS > Λ4 gauge cypress (210 > < 297 mm) II I--KI- II I---r, HV ^ I -1 I-II, 1τ Read t and note the general matters again Fill in this buttercup) -48- A7 ___B7__ V.

Figure 5 shows a flowchart showing the process of deleting a title. As shown in the figure, the process starts at step S21, where the user specifies a title to be deleted. The processing flow then proceeds to step S2, where the CPU2 1 determines whether one of the digit block group, the digit block, and the digit stream associated with the specified title is also related to another title. If it is not related to another title, the processing flow proceeds to step S 2 3, where C P U 2 1 deletes the digital block group, digital block, and digital stream related to the specified title. On the other hand, if the result of the judgment made in step S 2 2 shows that a group of digital blocks, a digital block, and a digital stream are also related to another title, the digital block group, the number Deletion of metablocks and digital streams will make them disappear.

However, It should be noted that if the judgment made in step S 2 indicates the number related to the specified title; the metablock group, the digital block, and the digital stream are also related to another title, the specified title is basically not "Delete" In this case, 0 SD control circuit 9 outputs a message to the display, stating that the designated title is basically not deleted. After TITLE_002 is deleted as described above, the former TITLE_003 becomes TITLE_002, and the former TITLE_004 becomes TITLE_003, as shown in Figure 5 3. At the same time, the former CHUNKGROUP_001 number block is divided into CHUNKGROUP.OOl R CHUNKGROUP_002, and the former CHUNKGROUP_002 is changed to CHUNKGROUP_003. Moreover, the former STREAM_001 number stream is divided into STREAM ^ OOl and STREAM_002. The above description shows that it is generally deleted. Title exercise In order to increase the size of the free area, on the other hand, there is also a technology that deletes a title by eliminating only the information used as control information on the title. In this case, it occupies one of a substantial area The meta stream is not actually deleted, so the digital block group, digital block, and digital stream associated with the title are not changed at all, even if the title is deleted. Second, the title will be described with reference to the flowchart shown in FIG. 54. As shown in the figure, the process starts from step S 31, where the user specifies the title to be merged. For example, the title to be merged is TITLE_002 and TITLE_003 shown in FIG. 4 9.

In this example, all The name of the manufacturing case is TITLE_00'2. Then the processing flow proceeds to step S 3 3. To execute the deletion process of the title before the combination. In this case, delete the previous TITLE_002 title and TITLE_003. After that, the processing flow continues to step S34, where the CPU 21 processes the information file of the title after the merged title. More specifically, in this case, TITLE_004 shown in Fig. 49 is changed to TITLE_003. As a result, the title shown in Fig. 27 is obtained. It should be noted that in the example mentioned above, the 2 titles are grouped in the same block group and are adjacent to each other. In another case, the 2 titles to be combined have their own set of digital blocks, digital blocks, and digital streams. In the process of combining these two headings, the digital block group, the digital block, and the digital stream are rearranged in order, and the titles are combined to form a single digital block group. Next, a program will be described. The operation of playing back a program means collecting the required parts of each title and playing back the collected parts without performing irreversible editing on the raw material, that is, the bit stream. The structure used to do this is called a project. The operation of playing back a program is also called an index playback operation. -The program contains multiple play sequences, each of which contains multiple playlists. A playback sequence controls an output channel. Specifying which output channel \ channel of a disc device to a playback sequence is determined according to the specifications of the disc device. The playlist of the play sequence is used to indicate the overlap of the decoding and display operations of each playitem along the time axis.

However, in the example of this format, a program has only 1 play sequence, and there is only 1 play and 1 play list. A play list contains play items, which are arranged so that each play item does not overlap in display time. In the program, the play item is represented by a pair of inner and outer points, which point to an area of a title. At the connection point between play items, a playback operation may be seamless or sometimes not. That is not Ensure a seamless operation. Referring to the flowchart shown in FIG. 55, the setting processing of the operation of playing back a program will be explained. Now suppose, for example, that in a state, PROGRAM_001 shown in FIG. 27 exists, and another PR0GRAM_002 is generated. As shown in FIG. 55, the process starts from step S41, where the user specifies a title and the inner and outer points in the title to be played back. For example, the predetermined first and second positions in TITLE_003 are designated as internal, respectively And the outer point 11 is shown in FIG. 5 6. The process of processing then proceeds to step S 4 2, where the CPU 2 1 sets the title specified in step S 4 1, that is, TITLE_003 in program.

PGI as one of the files used to store program (), and records the file on disc 1. Attention should be paid to the name of the file; the symbol $$$ in the name is the number of the program produced. Therefore, the '$$$' symbol in this example is 002. As above, the program_002 shown in Figure 56 is generated. Second, refer to The flowchart shown in Figure 57 illustrates the process of playing back a program. The process starts from step S 51. Here, once the user installs the optical disc 1 on the optical disc device, the CPU 21 reads out the information file from the optical disc 1, which contains the information shown in FIG. 27 or 56. Repeat this basic operation to read in one of the information files described earlier. The CPU21 stores the information file in the RAM unit 24. More specifically, first, the CPU2 1 reads VOLUME.T0C and ALBUM.STR, and then asks the file system about having an extension file i.PGI " · The number of files under the directory. A file with an extension file *. PG I " is a file used to store information on a program playback file. The number of each file with extension file *. PGI "is the number of programs that can be played back. In the example shown in Figure 27, the number of files with extension file" .PGI "is 1. On the other hand In the example shown in FIG. 56, the number of files each having an extension file *. PGI ^ is 2. The processing flow then proceeds to step S52, where the CPU 21 controls 0 the SD control circuit 9 and is stored in the RAM 2 4 Read out information such as the number of programs that can be played back, their length, and their nature, and enter these to the display unit.

Then, the processing flow proceeds to step S 5 3, where the user specifies that the playback is required. One program. Since there are 2 programs available for playback in the example shown in Figure 56, the user specifies one of the two by the operation input unit 14. When the user specifies a program to be played back, the processing flow continues to step S 5 4, here, CPIJ2 1 performs an operation to play back the specified program. In the playback operation of the specified program performed in step S 54, the program is played back from the position indicated by the specified in point to the position indicated by the specified out point. For example, in the operation playback, the example shown in FIG. 5 6 is played back. In the case of PROGRAM_001, playback ranges from one of TITLE_001's in-points to one of the out-points and from one of TITLE_003's in-points to one of the out-points. On the other hand, in the case of operating playback PROGRA1VL002, it is played back from TITLE_003 A range from one in point to one out point. Then, the process flow proceeds to step S 5 5 'Here CPU 21 determines whether the operation of playing back a program has been completed. If the operation is not completed, the processing flow returns to Step S 5 4 'The process of this step and subsequent processes are repeatedly performed. On the other hand,' if the judgment result made in step S 5 5 indicates that the operation of playing back a program has been completed ', the processing flow proceeds to step S56, Here, the CPU 2 1 determines whether there is another program to be played back. If there is another program to be played back, the processing flow returns to step 5 5 3 v to repeat the processing in this step and subsequent processing. Another If the result of the judgment in step S 56 indicates that all programs have been played back, then the processing is terminated.

As shown in Figure 59, a play sequence contains any arbitrary number of playlists. A playlist describes any arbitrary number of play items corresponding to a predetermined time (time stamp). In the example shown in Fig. 59, the playlist 1 shows the play item 1, play item 2, play item 3, play item 6, and play item 7 to be played back one by one. On the other hand, ... Playlist 2 describes the playback item 4 to be played back, starting from the middle of playback item 2 to the end of playback item 3. As for playlist 3, to play back play item 5, the time starts from the middle of play items 3 and 4 to the end of play item 6. Therefore, in the operation of playing back this play sequence, play item 1, play item 2, play item 3, play item 6, and play item 7 are played back one by one, and at the same time, play back play item 4, and time since play item 2 It starts from the middle to the middle of play item 3, and plays back item 5 at the same time. The time starts from the middle of play items 3 and 4 to the middle of play item 6. The relationship between a program, a play sequence, and a play item is summarized as a single diagram shown in FIG. In summary, a program contains any arbitrary number of play sequences, each containing any arbitrary number of playlists, and each of which contains any arbitrary number of play items. As described so far, the present invention has been exemplified by its application to an optical disc device.
