DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic user interface (GUI) technology, and more particularly, to a GUI operation for a part (still image or short-time repeating moving image) in a reproduced video from a disc. The present invention relates to a background image capturing system that can be freely captured as a background image via a computer.

2. Description of the Related Art In recent years, a DVD playback system for a moving image, which plays back an optical disk on which digital data such as video and audio data is recorded, has been developed. Is progressing. In accordance with the MPEG2 system layer, this DVD standard supports MPEG2 as a moving picture compression method, AC3 audio, MPEG audio, linear PCM, etc. for audio, and sub-picture data obtained by run-length-compressing bitmap data for subtitles. Control data (navigation pack) is added for special playback such as fast rewind. In addition, the DVD standard conforms to the ISO 9 standard so that data can be read by a computer.
660 and UDF bridge (micro UDF) are supported. Furthermore, in the DVD standard, a multi-angle function (a function of recording moving image data of various angles progressing simultaneously in a time-division manner and reproducing only one desired angle), a menu function (a simple language for menu: navigation) Commands are added, and functions such as a menu display function that combines main video data (main video) and subtitle data (sub-video) are included, enabling an unprecedented interactive way of enjoying.

Here, the menu functions include a function of displaying a button selected by a user's selection and a color changing function (highlight function) of a button indicating that the button is selected. As for the menu, the video manager menu domain (VMGM_DOM) implements the title menu. And VTS menu
The domain (VTSM_DOM) is the root menu, audio menu, sub-picture menu, angle menu,
A part-of-title (PTT) menu (or chapter menu) is realized. The title creator
These menus can be created freely, but if an audio menu, sub-picture menu, angle menu, or PTT menu exists, it must have a link function (call function) to these menus. Generally, a DVD player is provided with a root menu call button and a title menu call button as a user interface for calling the menu, and when the user calls each menu, a menu screen is displayed on a TV monitor. ing.

[0004]

By the way, before the DVD player starts the reproducing operation, the DVD player itself has its own background image (usually a mere blue screen or a still image containing a logo indicating the player maker). Or the player itself outputs a unique screen saver image (moving image including a simple animation).

However, the background image is unique to the player, and the user can always show the same image as long as the player continues to use the background image. However, people become tired of being repeatedly shown the same thing, and they want another background image.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a background image capturing system that allows a user to freely use a desired image (still image or short-time repeating moving image) as a background image. To provide.

[0007]

In order to achieve the above-mentioned object, a background image capturing system according to the present invention provides a recording information (VTSTT_DATA) including a video from an information medium (10).
VOBS) (DVD player in FIG. 1). Here, a predetermined navigation menu (FIG. 13) is displayed by a user operation (ST in FIG. 19).
500 to ST502), a predetermined capture menu is displayed from the navigation menu by the user's operation (ST504 to ST506), and a still image of a part of the video reproduced from the information medium or a moving image repeated for a short time is displayed on the background. Captured as an image (ST50
8-ST514). In such a system, when the recorded information is not reproduced from the information medium (standby state or stopped state before reproduction starts), the captured background image can be used as a background image of the device. Be composed.

Information is recorded. That is, one VTS includes one or more PGCs, one PGC includes one or more programs, one program includes one or more cells, and one cell includes a plurality of video object units V.
It is composed of OBU. The data of each cell is composed of multiple VOs.
BU is cut and recorded. Each VOBU has a navigation pack NV_PCK at the beginning, and further includes various types of data packs (audio packs A_PC
K, video pack V_PCK, sub-picture pack SP_PC
K etc.). Each pack is composed of a pack header and one or more packets. here,
A pack is a minimum unit for performing data transfer processing.
On the other hand, the minimum unit for performing logical processing is a cell, and logical processing (reproduction or the like) is performed in this unit, whereby the reproduction order can be changed or branching can be performed.

Each navigation pack NV_PCK is
A pack header, a system header, a packet header of a PCI packet, and a sub-stream I of a PCI packet.

And a button information table. The button information table includes one or more button information (not shown),
Each button information includes button position information, adjacent button position information, and a button command. The button position information includes the button color number information and the button position information (X
-Y coordinate information), auto action mode information indicating a button selection / activation (action) state, and the like.

For example, when a menu screen is reduced and a plurality of menus are simultaneously displayed on one screen, a button operation may be performed from the reduced menu.
In this case, since the actual button position (the mark operated by the user when selecting a menu item) is shifted from the case where the image is not reduced, it is necessary to correct the position data of the button so as to match the reduced menu. The correction of the position data includes the display position of the reduced menu on the screen (for example, the XY coordinate of the upper left corner of the reduced menu display area), the reduction ratio (1/2 or 1/4, etc.), and FIG. This can be performed based on the button position information.

In the DVD video system, a simple language called a navigation command is prepared in order to enhance interactivity. The button command in FIG. 3 is also a kind of navigation command, and when the button is activated (action), the corresponding navigation command is executed. This navigation command is transmitted before and after the reproduction of the program chain, after the reproduction of the cell, after the reproduction of the VOBU, the navigation pack NV_
Each can be performed during the PCK process.

FIG. 4 is a diagram for explaining the types of menu information recorded on the DVD disk of FIG. 2 and the hierarchical structure of the menu used in the DVD player 1 of FIG. This diagram is also a conceptual diagram for explaining the correspondence between the system menu and the user operation functions.

In a DVD player, a title menu and a root menu (main menu) are essential, and the title menu is a video manager menu (V
MGM), and the root menu is handled by a video title set menu (VTSM).

As shown in FIG. 3, the video title set menu has a hierarchical structure composed of a root menu and various lower hierarchical menus. Here, the category (VTSM_PGC_CAT) of the program chain for the video title set menu is configured as follows. That is, although not shown, VT
The lower 8 bits of SM_PGC_CAT are assigned to the lower bits of the parental identification field, the next 8 bits are assigned to the upper bits of the parental identification field, the next 4 bits are reserved as a reserved field, and the next 2 bits specify the block type. The next two bits specify the block mode, the next four bits describe the menu identifier (menu ID), the next three bits are reserved as a reserved field, and the last one bit (the 32nd bit) is the entry type. Is specified.

First, if the first entry type is 1b (binary 1) counting from the upper bit of 4 bytes (32 bits), it indicates that the corresponding program chain (PGC) is the entry PGC, and if it is 0b, it corresponds. This indicates that the program chain is a program chain other than the entry PGC.

The contents of the subsequent 4-bit menu identifier (menu ID) are determined as follows. If the entry type is 0b, 0000b is entered in the menu ID, and if the entry type is 1b, the following binary code is entered in the menu ID.
That is, 0011b is entered for the root menu, 0100b is entered for the sub-picture menu, 0101b is entered for the audio menu, 0110b is entered for the angle menu, and 0111b is entered for the part of title (such as chapter) menu.
Is entered. Other 4-bit binary codes of menu identifiers (menu IDs) are reserved for other uses.

If the 2-bit block mode following the menu identifier (menu ID) is 00b, it indicates that it is not the program chain in the corresponding block, and if it is 01b, it indicates that it is the first program chain in the corresponding block. If it is 10b, it indicates that it is the program chain in the corresponding block.
If it is b, it indicates that it is the last program chain in the corresponding block. The following 2-bit block type is 0
If it is 0b, it indicates that it is not a part of the corresponding block, and if it is 01b, it indicates that it is a parental block (a block whose reproduction is allowed only under specific conditions). The subsequent 8 + 8 bits are an area in which information (flag bit string) for determining the reproduction condition of the parental block is described.

FIG. 5 is a diagram for explaining a part of the user operation control information recorded on the DVD disk of FIG. This figure shows the user operation control (UOP0, UOP1) in the title reproduction type TT_PB_TY in FIG. 2, the user operation control (UOP0 to UOP24) in the user operation control PGC_UOP_CTL in FIG. 2, and the user operation control VOBU_UOP_CTL in FIG.

Then, the management information is read from the part storing the management information of the disc being reproduced, and the attribute information relating to the angle is referred to. The attribute information on the angle is described in the angle information in the PCI or DSI in FIG. For example, in the case of a DVD, nine angles of streams can be divided and recorded. The division unit is called an interleave unit, and the interleave unit is recorded in an interleaved manner. The angle information describes the next address of its own interlib unit next to each stream, and the size of the unit. Therefore, by referring to the angle information, it is possible to recognize how many angle streams are recorded.

Therefore, in the apparatus according to the embodiment of the present invention, by referring to the angle information, it is possible to grasp which stream number is the angle selected at present. Based on this grasp, a display like angle 1/5 can be obtained as shown in FIG. 14 (step D13). When the angle selection image 613 is designated by the cursor and the enter key is pressed,
The display showing the currently selected angle can be switched. Here, for example, when a predetermined position of the cursor control button is pressed, a display indicating the next angle is obtained. For example 2 /
5 is obtained. Thus, the angle can be switched one after another (step D15). When the angle display is switched, the video stream being reproduced is naturally switched to the specified angle. Then, the user presses the enter key when the stream of the desired angle is obtained (step D14).

FIG. 18 shows in more detail the description contents of the video title set audio stream attribute table (VTS_AST_ATRT) and the description contents of the video title set sub-picture stream attribute table (VTS_SPST_ATRT) described in VTSI. Is shown.
