VD (Digital Versatile Disk) is rapidly spreading.
Currently widely used DVDs are single-sided, single-layer recording.
Data with a capacity of 7 Gbytes (Giga) or 9 Gbytes in single-sided, dual-layer recording can be recorded. As described above, attention has been paid to the future development of DVDs that can encode a large-capacity moving image, audio, data, and other signals and digitally record them.

[0003] These DVDs are classified into a read-only type in which data cannot be written and a DVD in which data can be newly written or rewritten. The former includes a DVD-Video recording video such as a movie and a DVD-Audio recording music and the like, and the latter includes a DVD-R
W (Rewritable) or DVD-RAM (Random Access Memor)
y).

[0004] In the current DVD standard, there is control data in which information on recorded contents and the recording medium itself is recorded. In the information area, information on the attribute of the content, the definition of the structure of the volume, and the reproduction control of the title are recorded. DV
The D playback device refers to text information on the volume structure included in the control data and displays the content. Further, as necessary, a menu incorporating a still image corresponding to the chapter has been used as a menu of the DVD recording medium in order to reproduce each chapter (delimiter) of the title.

In a personal computer,
For example, if a DVD-ROM device into which a DVD recording medium is inserted is displayed by using a file operation tool such as Explorer in Microsoft Windows, a DV

A menu system creating section 46 for creating a menu system from the directory structure information created by the creating section 44, and a DVD recording medium 10 capable of writing the menu system created by the menu system creating section 46.
And an image database creating unit 47 for recording the information in the image database.

The control data analyzer 43 reads and analyzes the control data sent from the navigation data read circuit 35 and held in the memory 41. As a result of this analysis, information such as the volume of the DVD recording medium 10 itself, the definition of a title and the definition of a chapter, and the like are recorded from the control data. The extracted title definition and chapter definition are sent to the directory structure creation unit 44.

The directory structure creating section 44 creates directory structure information indicating the logical relationship of the contents recorded on the DVD recording medium 10 based on the title definition and chapter definition obtained by the control data analysis section 43. I do. Specifically, the directory structure creation unit 44 receives information such as title definitions and chapter definitions analyzed by the control data analysis unit 43, and performs mapping based on this information to visualize directory configuration information. Create graphics data. The graphics data created by the directory structure creation unit 44 is stored in the memory 41.
By using the graphics data, not only the directory structure information is displayed, but also the reproduction of the corresponding content is started by selecting and confirming the directory (elements such as titles and chapters) of the displayed directory structure information. A user interface can be provided. This user interface is called a disc guide.

The image link unit 45 adds, for each directory of the directory structure information created by the directory structure creating unit 44, a representative image representing the directory. This representative image is displayed on the DVD recording medium 10.
Can be a still image file of a predetermined scene extracted from the video data recorded in the image data. The file of the created representative image is stored in the memory 41.
Originally, control data is provided with fields for setting text information on titles, chapters, and the like. However, by adding an ID to the still image file of the above-described representative image, providing a field for writing the ID of the still image file in the text information of the control data, and describing the ID of the corresponding still image file, the directory structure is improved. A still image file of a representative image recorded as a file different from the graphics data of the above can be linked. In this way, the representative image can be embedded in the graphics data of the directory structure information created by the directory structure creation unit 44. Here, the representative image is
For example, it can be automatically created by cutting out a still image from the video at the beginning of each chapter. In addition, a still image of a scene arbitrarily selected from a video of a chapter corresponding to the user can be cut out to be a representative image. This still image file is a bitmap or J
It can be created in a general data format such as PEG (Joint Photographic Experts Group). In addition,
By the same method as described above, a representative image can be added to a directory other than a chapter such as a title, and it is needless to say that it is not always necessary to add a representative image to all chapters.

As described above, the graphics data having the directory structure created by the directory structure creating section 44 is stored in the memory 41 with a field for embedding the ID of the representative image. The still image file of the representative image having the ID created by the image link unit 45 is also stored in the memory 41. As a result, the graphics data having the directory structure is stored in the memory 41 with the representative image embedded therein. The data stored in the memory 41 is sent to the synthesizing unit 34 of the A / V decoder unit 30 and sent to the video output unit 51 of the reproducing unit 50. The graphics data of the directory structure information displayed on the display device connected to the outside of the DVD reproducing device will be described later in detail with reference to FIG.

The menu system creating section 46 gathers chapters arbitrarily selected by the user from the displayed directory structure information and creates a menu system unique to the user. In this menu system,
Create a menu screen that lists the chapters selected by the user. On this menu screen, a still image of an arbitrary scene selected by the user from the corresponding chapter can be used as the representative image, and text information describing information about the chapter can be edited. The menu screen will be described later in detail with reference to FIG. Note that information on the created menu system can be written and stored in the DVD recording medium 10 on which data can be additionally written or rewritten.

The image database creating section 47 records the menu system created by the menu system creating section 46 on the writable DVD recording medium 10 as an image database. Once the created menu system is stored, the user controls the reproduction of the content from the next time using the menu screen of the menu system instead of the directory structure information created by the directory structure creating unit 44. It becomes possible.

Next, the operation of this embodiment will be described with reference to a flowchart. FIG. 3 is a flowchart showing the flow of processing from the start of the DVD playback device to the start of the disc guide in the present embodiment. First, when the DVD reproducing apparatus is started and the DVD recording medium 10 is inserted (step 101), first, the DV
The data recorded on the D recording medium 10 is a pickup 11
Is read as an optical signal. Pickup 11
The optical signal read by the A / V decoder 30 is sent to the A / V decoder 30 as data via the front processor 20. The data sent to the A / V decoder unit 30 is separated into control data and object data by a separation unit 31. The control data is read by the navigation data read circuit 35 and sent to the system control unit 40, and the memory 41 (Step 102).

Next, the control data stored in the memory 41 is read out by the system controller 42,
The data is analyzed by the control data analysis unit 43 (step 103). Then, based on the control data analyzed in step 103, the directory structure creating section 44 creates graphics data of directory structure information (step 104). After this, step 10
The graphics data created in step 4 is stored again in the memory 41 (step 105). At this time, the image link unit 45 automatically creates a still image file at the head of each chapter of the directory structure information. The created still image file is also stored in the memory 41 similarly to the graphics data of the directory structure information. An ID is assigned to such a still image file, and the ID of the corresponding still image file is embedded as a representative image in the graphics data of the directory structure information. The operation up to this point is automatically executed in response to activation of the DVD reproducing device or insertion of the DVD recording medium 10.

Next, a determination is made as to whether or not the user has requested a disk guide activation (step 106).
When a user requests a disk guide, a disk guide is started (step 107). It is assumed that the disk guide activation request in step 106 is performed by an operation device such as a controller attached to the DVD playback device, for example. If there is no request to start the disk guide in step 106, the apparatus enters a standby state.

FIG. 4 is a flowchart showing the flow of processing from the time when the content recorded on the DVD recording medium 10 is selected using the disc guide to the time when the video is reproduced in this embodiment. First, a disk guide is activated by a user's operation of a controller or the like (step 201). When the disk guide starts,
The graphics data of the directory structure information stored in the memory 41 and the still image data of the representative image are A /
The video signal is sent to the synthesizing unit 34 of the V decoder unit 30 and is synthesized with the video signal (step 202). The synthesized video signal is sent to the video output unit 51 of the playback unit 50, and is displayed as a disc map on a display device connected to the DVD playback device (step 203). With this disc map, the user can visually recognize the logical structure of the content recorded on the DVD recording medium 10, and can select desired content by intuitive operation and instruct reproduction. You can do it.

Next, the user performs an operation of selecting a desired content on the disc map displayed in step 203 (step 204). This operation
This is performed by moving between layers in the directory structure of the disc map or moving within the layers, and it is possible to select a chapter unit or a title unit. This operation on the disk map is performed by an operation of a controller or the like.

Next, it is determined whether or not there is a reproduction request (step 205). When there is a reproduction request from the user, the directory structure information displayed as the disc map and the object data which is the target file linked to the still image are searched for, and the reproduction of the file is started ( Step 206),
The disk guide ends (step 207). If there is no reproduction request in step 205, the process returns to step 204, where the operation by the user is accepted. The reproduction request in step 205 is, for example,
It can be performed by an ENTER button or the like provided on an operation device such as a controller attached to the DVD playback device.

That is, the still image data of the scene arbitrarily selected by the user from the video data in the chapter is cut out as the representative image and embedded in the image information 71. Also, the text information 72 can be arbitrarily rewritten. This not only displays text information originally attached to titles and chapters,
It is possible for the user to add a description or the like of his choice, and to create a menu unique to the user.

By creating a menu system that is uniquely configured for the user, it is possible to provide a more convenient interface for the user than when the disc map 60 is used. In this case, in the disc guide in the operation shown in FIGS. 3 and 4, instead of displaying a disc map describing directory structure information, a menu screen 70 of the menu system can be displayed. In this way, the user can reproduce a desired chapter by using a menu in which his or her favorite chapters are collected without searching for a chapter using the disc map 60.

For the menu system described above, a search keyword 81 for a chapter can be set on the search screen 80. In the search keyword 81, the genre of the content for each chapter and the like can be recorded. In this way, DVD
Only a desired genre can be retrieved from a plurality of contents recorded on the recording medium 10 and reproduced.
