[0033]
8 to 12 are diagrams showing the editing operation in the present invention. FIG. 8 is a diagram illustrating the first division processing. When a cell having a still image unit (ASVU) is divided, the same ASVU cannot be referred from another cell after editing. For this reason, an ASVU # 2 which is a copy of the same data as the ASVU # 1 is created, and the front cell refers to the ASVU # 1, and the rear cell refers to the ASVU # 2. ASVUI). The ASVU numbers referred to by the subsequent cells are added one by one in order.
[0034]
FIG. 9 is a diagram illustrating the second division processing. When a cell is split, the ASVUI is inherited by the preceding cells and does not remain in the following cells.
[0035]
FIG. 10 is a diagram illustrating the third division processing. The third division process is a method in which the ASVOB allocated to each program after the division is changed according to the length of the track to be divided and the playback time of the ASVOB. In this case, the ASVOB is a method of allocating half the ASVOB regardless of the division point of the program. When the ASVOB is an odd number, the center sheet is allocated to one of them.
[0036]
FIG. 11 is a diagram illustrating the fourth division processing. The fourth division processing is a method in which the number of sheets to be allocated changes according to the relation between the division point of the program and the playback time of ASVOB. In this case, four ASVOBs have been allocated to the cell before the division. However, when dividing, since the division point was located before the center of the cell, the allocation of the ASVOB after the division is performed by ASVU # 1: ASVU # 2. 1: 3. If the dividing point is behind the center, the ratio may be 3: 1, if any of the divided cells is sufficiently large, 0: 4, 4: 0, and if the cell is approximately at the center, 2: 2. .
[0037]
Similarly, when a certain cell of the representative image (REP_PICT) is divided, a method of copying the ASVU and designating each ASVU, a method of inheriting only the preceding cell, and a method of inheriting each reproduction time can be considered.
[0038]
FIG. 12 is a diagram illustrating a process of combining cells having ASVU in both cells. In this case, one ASVU is created by combining the ASVU in the front cell and the ASVU in the rear cell and is referred to from the combined cells. At this time, the data structure is as shown in the still image unit 111 of FIG. ASVOB can contain only 99 pieces in one ASVU. For this reason, if there are 99 or more ASVOBs in the combined ASVU, the 99th or more ASVOBs are erased. In the instruction information file for referring to a still image, ASVUI_SRP_Ns is reduced by one and the number of ASVUIs is also reduced by one. Also, rewriting is performed so that ASVOB_Ns in the ASVUI is increased to a corresponding number. Alternatively, one of the ASVUs before the combination is selected and referred to, the still image data and the instruction information are also made to correspond to the ASVU, and one of them is invalidated.
[0039]
Further, according to the standard, the still image display time of a plurality of ASVOBs stored in one ASVU must be the same. That is, the still image display time of ASVOB # 1 and # 2 corresponding to ASVUI # 1 is the same, and the still image display time of ASVOB # 1 and # 2 corresponding to ASVUI # 2 is the same. However, the still image display time of ASVOB # 1 and # 2 corresponding to ASVUI # 1 may be different from the still image display time of ASVOB # 1 and # 2 corresponding to ASVUI # 2. In such a case, the still image display times of all the ASVOBs stored in one ASVU are unified according to the combining process. The still image display time is described in the ASV display information 726 shown in FIG. Specifically, the still image display time is defined as ASV_DUR = ASV_DUR * 100 [ms].
[0040]
FIG. 13 is a diagram illustrating division processing when a division point is specified in an RA section of a cell having a representative voice (RA). RA is, for example, a rust portion included in audio content information. The RA is defined in the audio content information according to the start position and the length. When a division point is specified in the RA section, RA is left only in the cell including the start point. Alternatively, a method of canceling RA can be considered. FIG. 14 is a diagram showing a joining process of two cells each having RA. When two cells each having an RA are combined, one of the RAs is inherited, and the other RAs are erased. Or a method of canceling both is also conceivable. In these cases, in the case of actual data, in the case of division, the description of the program and in the case of the division, the information of one RA is deleted and the description of the program information is changed.
[0041]
FIG. 15 is a diagram illustrating a case where a cell in which an index point (IndexPoint) is specified is divided. In this case, an Index is added to the head (division point) of the subsequent cell divided as shown in FIG. In the data structure, the portion related to the cell information search pointer group 73 and the cell general information 740 in FIG. 7 is changed along with the division of the cell, and a new Index is also added to the portion of the cell entry point information group 741. In this way, by adding the index to the division point, it is possible to easily find the reproduction information.
[0042]
