Control for dividing a part in the rear of the management information file as a new chapter of the first title, and control for writing a post command for jumping to the new chapter after reproduction of the second title in the management information file; And a second control including the above.

According to such a configuration, in the DVD-VIDEO format, data cannot be physically deleted in accordance with the standard. However, when the title is reproduced according to the management information file after editing, the reproduction of the designated deleted portion is skipped and not reproduced. From the viewpoint of the viewer, the part (cell) appears to have been deleted. That is, virtual deletion becomes possible. At this time, since deletion can be performed in cell units by using cell commands, editing with high practicality can be performed. Further, according to the first control, since the deleted portion can be skipped and the front and back of the cell can be continuously reproduced, it is possible to provide viewing that does not feel that the deleted / edited state is felt. Also,
According to the second control, the second title is reproduced instead of the deleted portion, so that the viewer can be notified that there is a deleted cell. Further, since the jump to the new chapter, that is, the portion behind the deleted portion, is made after the second title is reproduced, the viewer's hands are not bothered for reproduction after the deleted portion. Further, since the user can select the first control or the second control as the deletion method, the range of editing for the user is widened.

Furthermore, in order to achieve the above object, the present invention provides an editing apparatus for editing a title conforming to the DVD-VIDEO format, comprising: a control unit;

A cell command having a content for skipping the reproduction of the deleted portion after the reproduction of the cell is written into the management information file.

According to such a configuration, in the DVD-VIDEO format, data cannot be physically deleted in accordance with the standard. However, when the title is reproduced according to the management information file after editing, the reproduction of the designated deleted portion is skipped and not reproduced. From the viewpoint of the viewer, the part (cell) appears to have been deleted. That is, virtual deletion becomes possible. At this time, since deletion can be performed in cell units by using cell commands, editing with high practicality can be performed.

The cell command is preferably a cell command in which the playback order moves to the next cell of the deleted portion after the previous cell is played back. According to such a configuration, the deleted part can be skipped and the cell can be continuously reproduced before and after the cell, so that it is possible to provide viewing that does not feel that the edited data has been deleted.

In addition, a second title is further recorded on the recording medium, and the second title is also defined in the management information file. The cell command is transmitted after the previous cell is reproduced. A cell command for jumping to two titles, wherein the control unit divides a part of the first title that has a playback order later than the deleted part into the management information file as a new chapter of the first title, It is preferable that a post command for jumping to the new chapter after the reproduction of the second title is written in the management information file. According to such a configuration, since the second title is reproduced instead of the deleted portion, it is possible to notify the viewer that there is a deleted cell. Further, since the jump to the new chapter, that is, the portion behind the deleted portion, is made after the second title is reproduced, the viewer's hands are not bothered for reproduction after the deleted portion.

Neither of the above-mentioned patent documents 1 and 2 discloses a technique for performing virtual deletion editing in cell units by using cell commands.

According to the present invention, it is possible to provide an optical disc apparatus and an editing apparatus capable of deleting and editing a title of a DVD-VIDEO format in cell units.

Here, FIGS. 2 and 3 are schematic diagrams for explaining the DVD-VIDEO format. As shown in FIG. 2, in a DVD compliant with the DVD-VIDEO format,
One video manager VMG and one or more video title sets VTS are recorded in the D video area (or DVD video zone). FIG. 2 illustrates three video title sets VTS.

The video manager VMG includes video manager information VMGI, a menu video object set VMGM_VOBS, and a backup VMGI_BUP. On the other hand, the video title set VTS includes video title set information VTSI, a menu object set VTSM_VOBS, and a title video object set VT.
It consists of STT_VOBS and backup VTSI_BUP.

The video manager information VMGI is information for managing and controlling the entire DVD video area, and the video title set information VTSI is information for managing and controlling the video title set VTS.

The title object set VTSTT_VOBS is a video title set V
This is the playback content of the title included in the TS, and there is a unit called “cell” (see FIG. 3) as one of the units for storing and managing the content. Each cell 93 is given a unique identification number or ID number. By specifying this identification number, the reproduction order of the cells 93 can be defined, and thus the cells 93 that are continuously reproduced are designated. A group constitutes one title 91. The means for realizing the reproduction information of the cell 93 in each title 91, that is, the reproduction order information of the cell 93 is called a program chain PGC (see FIG. 3).

As shown in FIG. 3, the program chain PGC (in other words, title 91) is DVD2
00, the management information file 90 corresponds to the video manager information VMGI and / or video title set information VTSI file (so-called IFO file).

FIG. 3 illustrates the case where the management information file 90 includes one program chain PGC. However, the management information file 90 may include a plurality of program chains PGC. As shown in the structure diagram of FIG. 3, in the program chain PGC, the identification number of the cell to be reproduced first, the identification number of the cell to be reproduced secondly,... Are related to the playback order. FIG. 3 illustrates the case of specifying up to the sixth, but the description “cell # 1” in the figure means “the first cell to be reproduced”, and the cell identification number is not necessarily “1”. Does not match.

In the program chain PGC, a pre-command 95 which is a command executed before reproducing the first cell # 1, a post command 96 which is a command executed after reproducing the last (sixth in this case) cell 93, A cell command 97 which is a command executed when the cell 93 is reproduced can be placed. In addition, continuous cells in the program chain PGC can be defined in the unit of “chapter” in the management information file 90,
FIG. 3 illustrates a case where one title 91 is composed of two chapters 92.

Next, the operation of the DVD device 1 (in other words, the side of the DVD device 1 as an editing device) or the control by the control unit 10 when editing the title 91 compliant with the DVD-VIDEO format will be described.

First, FIGS. 4 and 5 are a schematic diagram and a flowchart for explaining the first editing method ST10. Here, as shown in FIG. 4, a case where the title 91 to be edited recorded on the DVD 200 includes a chapter 92 and the chapter 92 includes six cells 93 is taken as an example. The DVD 200 has a management information file 90 that defines title 1.
Is also recorded.

Here, “title 91 is recorded on DVD 200” means that a group of cells 93 which are reproduced according to management information file 90 recorded on DVD 200 and form title 91 are recorded.

In the first editing method ST10, the user designates or selects a cell 93 (here, the reproduction order is the fourth cell 93) and deletes the cell 93 by operating the remote controller 51 (see FIG. 1) or the like. If the instruction to do so is input, the main control unit 10 in FIG.
As shown, the instruction is acquired through the input unit 50 (see FIG. 1).

By acquiring such an instruction, the main control unit 10, as shown in step ST12 in FIG. 5, causes the third cell 93 whose playback order is one before the cell 93 specified by the user (in other words, the deleted portion). After the reproduction, the cell command 97 having the content of skipping the reproduction of the designated cell 93 is written into the management information file 90 in the DVD 200 by controlling the DVD drive unit 20 (
First control). More specifically, a cell command “LinkCN 5” that moves to the fifth cell 93 in the reproduction order one after the designated cell 93 after the reproduction of the third cell 93 is stored in the title 91 of the management information file 90. Program chain PGC describing the playback information of
Write against.

When a plurality of continuous cells 93 are to be deleted, the main control unit is configured so that a cell command “LinkCN” is described by setting the cell 93 next to the deleted portion consisting of such a cell group as a movement destination. Ten execution programs may be created.

Next, FIGS. 6, 7 and 8 show a schematic diagram and a flowchart for explaining the second editing method ST20. Here, on the DVD 200, as shown in FIG. 6A, the title 91 similar to that of FIG. 4 described above is recorded as the first title 91 to be edited (“title # 1” in the figure). In addition, a second title 91 (shown as “title # 2” in the drawing) shown in FIG. 6B is recorded. Note that the second title 91 includes one chapter 92, and the chapter 92 is an example in which the second title 91 includes one cell 93 corresponding to an image that informs the viewer of cell deletion.

Further, it is assumed that a program chain PGC and the like are defined for both the first title 91 and the second title 91 in the management information file 90 (see FIG. 3) in the DVD 200. In other words, the “management information file 90” is a generic name for files in which the program chains PGC and the like of the first title 91 and the second title 91 are defined.

As shown in FIG. 8, in the second editing method ST20, when the instruction to delete the designated cell 93 (here, the reproduction order is the fourth cell 93) is acquired from the user, as in step ST11 described above. The main control unit 10 performs step ST21 including steps ST21A, ST21B, and ST21C (second control).

First, as shown as step ST21A in FIG. 8, the main control unit 10 has a third cell 93 whose playback order is one prior to the cell 93 designated by the user (in other words, the deleted portion).
After the reproduction, the cell command 97 having the content of skipping the reproduction of the designated cell 93 is written into the management information file 90 in the DVD 200 by controlling the DVD drive unit 20. More specifically,
After playback of the third cell 93, the cell command “JumpT” jumps to the second title 91.
T 2 ″ is written to the program chain PGC in which the reproduction information of the first title 91 is described in the management information file 90.

Further, as shown in step ST21B in FIG. 8, the main control unit 10 newly sets a portion of the first title 91 whose playback order is behind the deletion designation cell 93 (here, the fifth and sixth cells 93). Divide into chapters 92 (see FIG. 7). Such chapter division is performed by the chapter 9 in the first title 91 in the management information file 90.
This is possible by changing the definition of 2 and updating the management information file 90 in the DVD 200. After the division, as shown in FIG. 7, the first to fourth cells 93 remaining in the division source
The first chapter 92 (denoted as “Chapter # 1” in the figure) is constituted by the second chapter 92 (denoted as “Chapter # 2” in the figure) by the new chapter 92 by the division. As a result, the first title 91 has two chapters 9.
It will be composed of two.

Further, as shown in step ST21C in FIG. 8, the main control unit 10 sends a post command 96 for jumping to the newly created second chapter 92 in the first title 91 after the reproduction of the second title 91 to the DVD drive. The unit 20 is controlled to write in the management information file 90 in the DVD 200. Specifically, the post command “JumpVtsPtt (1,2
”Is written in the program chain PGC in which the reproduction information of the second title 91 is described in the management information file 90.

Note that the post command “JumpVtsPtt” in step ST21C designates the jump destination by a chapter number, so that step ST21C is a chapter division step ST.
Although it is necessary to execute after 21B, the execution order of steps ST21A and ST21B may be reversed from the above example.

In the above example, the DVD 200 is provided for each of the steps ST21A, ST21B, and ST21C.
The management information file 90 is written into the DVD 200, but after the processing in steps ST21A, ST21B, and ST21C is performed on the management information file 90 on the memory 12 of the main control unit 10, the information is written to the DVD 200 collectively. You may comprise as follows. Even in such a case, the changes made in steps ST21A, ST21B, and ST21C are changed to DVD2.
It is still written in the management information file 90 in 00.

When deleting a plurality of continuous cells 93, the execution program of the main control unit 10 is divided so as to divide the part whose playback order is behind the deleted part consisting of such a cell group as a new chapter 92. Create it.

9 is applied to the first and second editing methods ST10 and ST20 described above.
The editing method ST30 can also be configured. In detail, the user controls the remote controller 51 (FIG. 1).
The cell 93 to be deleted and the deletion method (deletion by either the first control ST12 in the first editing method ST10 or the second control ST21 in the second editing method ST20) are designated or selected by an operation such as If the deletion instruction is given, the main control unit 10
As shown in step ST31, the instruction is acquired via the input unit 50 (see FIG. 1). And the main control part 10 performs deletion of the designated cell 93 by the designated deletion method, ie, 1st control ST12 or 2nd control ST21.

According to such a DVD device 1 or an aspect of the DVD device 1 as an editing device, a DVD
-In the VIDEO format, data cannot be physically deleted according to the standard. However, when the title 91 is reproduced according to the management information file 90 after editing, the reproduction of the designated deletion cell 93 is skipped and is not reproduced. It appears that cell 93 has been deleted.
That is, virtual deletion is possible. At this time, the use of the cell command 97 causes the cell 9
Since deletion can be performed in three units, editing with high practicality can be performed.

In particular, according to the first control implemented as step ST12, since the deleted cell 93 can be skipped and the front and back of the deleted cell 93 can be reproduced continuously, viewing that does not feel that the deleted cell has been edited is provided. be able to. In addition, the second implemented as step ST21.
According to the control, since the second title 91 is reproduced instead of the deleted cell 93, it is possible to notify the viewer that there is a deleted cell 93. At this time, after the reproduction of the second title 91, the jump to the new chapter 92 in the first title 91, that is, the deletion cell 93, may cause trouble for the viewer in the reproduction after the deletion cell 93. Absent. Furthermore, according to the third editing method to which the first control and the second control are applied, the user can select the deletion method, so that the editing range is widened for the user.

Even when a plurality of continuous cells 93 are deleted, the same effect as described above can be obtained.

By the way, the title 91 and the management information file 90 are not limited to the above-described DVD 200, but may be recorded on a recording medium writable via a recording medium drive unit under the control of the main control unit 10, for example, a hard disk unit. Even in the case where the title 91 and the management information file 90 are recorded on the hard disk 300 (see FIG. 1), the same control as described above can be applied via the hard disk drive unit 31 (see FIG. 1).

The DVD device 1 is a so-called (HDD built-in) DVD recorder.
The above-described control / operation, that is, an aspect as an editing apparatus can be realized by a configuration using, for example, a personal computer (whether a desktop type or a notebook type). Even in this case, the recording location of the title 91 and the management information file 90 is not limited to the DVD 200 as described above.
