Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program creating device and a program creating method, and more particularly to a program creating device and a program creating method for creating a control program for causing a device equipped with a computer to execute a predetermined function.

[0002]

2. Description of the Related Art In recent years, computer-mounted devices equipped with a microprocessor or the like have become widespread. In such a computer-equipped device, a desired function or operation can be realized by creating an arbitrary control program or information data describing a function or operation by a program creating device and loading it.

For example, in a DVD video, in addition to content data such as actual video and audio, information data for supporting functions such as multi-angle and random shuffle reproduction, and special reproduction such as fast forward and rewind. have. Further, it has an interactive menu and command data for jumping to an arbitrary title and menu by operating a button in the interactive menu. Such information data is called navigation data.

DVD video format UDF (Univ
(ersal Disc Format), a VMG (Video Manager), which is a logical area for a menu, and a VTS, which is an area for a title (a so-called video portion of the main part).
The structure of (Video Title Set) will be described. Figure 7
Is a format recorded in the UDF of the DVD. The DVD video format consists of one VMG and several VTSs. The VMG is VMGI (Video Manager Information) in which control information is recorded, and VMGM_V which is content for a title selection menu.
OBS (Video Object Set for VMG Menu) and VM
It is composed of VMGI (BUP) which is a backup of GI. Further, VTS is VTSI which is control information.
(Video TitleSet Information), VTSM_VOBS (Vi which is content for various menus in VTS.
deo Object Set for the VTS Menu), VTSTT_VOBS (Video which is the content for playing the title.
Object Set for Titles in a VTS) and VTSI (BUP) which is a backup of VTSI. Thus, the DVD video format incorporates VMGI and VTSI as control information. Moreover, a part of the control information is also included in the VOBS.

For VMGI and VTSI, PGCIT (Pr
ogram chain Information Table) is recorded.
FIG. 8 is a configuration example of PGCIT. The PGCIT is composed of a plurality of PGCIs, and the number of the cell forming the PGC is recorded in each PGCI. PGC is PGC
It consists of cells in I and VOBS. Also, PGC
I can have a pre-command to be executed before playing the first cell and a post-command to be executed after playing the last cell. Furthermore, as a command, a button on the menu screen is played when each cell is played. Button commands that are executed when you select and enter, and cell commands that are executed immediately after playing each cell are also prepared.

The function realized by such a command is edited by the DVD authoring device, which is a program creating device, converted into the format described above, and then recorded on the disc. A reproducing device for reproducing the created disc executes a predetermined function based on a command recorded on the disc.

[0007]

However, in the conventional program creating apparatus, there are problems that the function expansion is difficult and the management is complicated.

In the conventional program creating apparatus, the data defining the function using the data peculiar to the function realized by the editing software or the data required to create the control program are collectively handled, and the standard of the computer-equipped device is directly used. I was performing the process of converting to a format that suits. In this way, since the processing is not independent for each function, the sequence of creating control programs and information data by editing software becomes complicated,
And it was difficult to expand the function. Further, for such a reason, it is necessary to prepare some editing software based on the standards and specifications of the computer-installed device that creates the control program or the information data. Therefore, there arises a problem that the function construction of the control program and the information data and the management of the processing program suitable for the editing processing become complicated.

In order to reduce the management of such editing software, for example, a program loading device described in Japanese Patent Laid-Open No. 11-85224 discloses a control program built in a computer-installed device in which the program is incorporated and the control program. The editing software that enables editing is installed in advance, and the program creating apparatus reads the control program and the editing software installed in the target apparatus, and uses the read editing software to edit and incorporate the control program. However, there is an inconvenience that the computer-equipped device must have editing software that is not normally used.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a program creating apparatus and a program creating method in which functions can be easily expanded and maintainability is high.

That is, the information data is set, the information data is read from the outside, and the information data is written. Here, the information data unique to each function is the data defining the function or the information data necessary for actually creating the control program. For example, for title playback, stream switching, and jumping to a menu, information data relating to the title number, stream number, and PGC number of the menu are set, respectively. Further, the respective function 1 individual information managing means 110, function 2 individual information managing means 120 and function 3 individual information managing means 130
For example, by having mutual communication functions, necessary information data can be acquired from other blocks.

The control program creating means 200 comprises a command creating means 210 and a buffer 220. The command creating unit 210 provides information necessary for creating a navigation command, which is a control program for realizing a desired function, to the function 1 individual information managing unit 110, the function 2 individual information managing unit 120, and the function 3 individual information managing unit 130.
Read from and create a command. The routine for creating the navigation command is configured independently for each function. The buffer 220 is composed of several blocks (buffer 1, buffer 2, buffer 3,
.., buffer n), and the command created by the command creating means 210 is stored in the buffer of the optimum block. That is, the buffer has a linked list structure, and the created command is inserted into a necessary buffer based on the weight associated with each function. The pre and post command area buffers conform to the DVD standard, for example,
It is prepared for each domain or each PGC.

The shaping means 300 converts the command data of the navigation commands stored in the buffer 220 into DV.
It is taken out based on the D standard and specifications and molded into the final format.

As described above, for each basic function, the function is expanded in order to manage the information data defining the function and the information data necessary for creating the navigation command (control program) for realizing the function. When
It suffices to create and add an individual information management unit that manages the function to be expanded, and does not affect the original individual information management unit. In this way, the function can be easily expanded. Further, even when a certain function is changed, an independent routine may be changed for each function of creating the information data and navigation command managed by the individual information managing means, and other individual information managing means may be changed. It is also possible to improve maintainability such that there is no impact. Further, since the created navigation command is stored in the buffer divided based on the standard or the specification, the subsequent molding process can be facilitated.

Next, the operation of the program creating apparatus and the program creating method according to the present invention will be described with reference to specific examples. As described above, the DVD video disc is composed of a plurality of menus and a plurality of titles. Figure 2 shows DV
It is an example of composition of VMG and its PGC of a D video disc. (1) is the VMG menu screen (VMGM, VM
This is an example of GMenu). The menu has buttons 1, 2, and 3 on one page. Less than,
This menu is called menu 1. (2) is the PG
It is C. It is composed of a pre-command area, a cell command area corresponding to the menu 1, and a post-command area. Each command recorded in the pre-command area, the cell command area, and the post-command area is created by the program creating apparatus of the present invention in the procedure described below.

FIG. 3 shows the V of a DVD video disc.
It is a structural example of TSM, VTS and its PGC. (1)
Is the VTS menu screen (VTSM, VTS Men
u) is an example. The menu has one button per page,
Button 2 and Button 3, Button 1, Button 2 on page 2
And a button 3 are provided. Hereinafter, this menu is referred to as menu 2. (2) is the PGC. It is composed of a pre-command area, a cell command area corresponding to each page of the menu 2, and a post-command area. Further, in the VTS, PGCs corresponding to a total of 7 chapters are recorded in the title 1, and PGCs corresponding to a total of 5 chapters are recorded in the title 2 as contents for reproducing the title. Similar to the above description, VT
The command recorded in the PGC of S is also created by the procedure described below.

A description will be given of a navigation command creation processing procedure in the case where the DVD video disc having such a configuration is provided with a title reproduction function, a title return function of returning to the menu after title reproduction, and a menu jump function of jumping to the menu.

DVD of the program creating apparatus according to the present invention
The object configuration of the authoring software will be described. FIG. 4 is a DVD showing an embodiment of the present invention.
This is the object structure of the authoring software.
The DVD authoring software has a hierarchical structure in which menus and titles on the GUI are objects (scene objects), and cells (pages, chapters) are objects in the objects. In addition, you can have a button object in the cell object. The GUI program holds these object data and updates them as needed.

Each object can have a navigation object which realizes a predetermined function such as the reproduction of the title. The DVD authoring software holds data by saving these as files. The navigation object has individual information (private data) individually and independently, and accordingly has a GUI for each function. These are function 1 individual information management means 110, function 2
Individual information management means 120 and function 3 Individual information management means 1
It is managed by 30 or the like, and when data is set by the GUI, the data is saved or loaded in the corresponding navigation object. For example, in the case of a navigation object for title reproduction or title return, it has the ID number of the scene object of the title of the jump destination. Also, in the case of a navigation object for menu jump, it has the ID number of the scene object of the menu at the jump destination.

Further, the navigation object is
An interface function (Co
It has a mmandGenerate_A ()). This function is the interface function (CommandGenerate_B ()) of the control program creating means 200.
Private data and data required for command generation are called as arguments. For example, in the case of title reproduction or title return, the scene object ID of the jump destination title
In addition to this, the button object ID and cell object I for which this title playback and title return exist
D, the scene object ID is passed as an argument. Similarly, in the case of a menu jump, in addition to the scene object ID of the jump destination menu, the button object ID, cell object ID, and scene object ID where this menu jump navigation object exists are passed as arguments.

Subsequently, the control program creating means 200 creates a navigation command based on the data acquired from the individual information managing means and inserts it into the buffer. The buffer block is based on the DVD standard and is based on the domain (VM
A pre-command area, a post-command area, a cell command area, or a button command area is prepared for each PCG (GM, VTSM, VTSTT). Here, the cell command and the button command correspond to one navigation object, which is one command, on a one-to-one basis. However, the pre-commands and post-commands are shared by each navigation object, as can be seen from the examples of the navigation commands described above.

As a mechanism for independently generating a navigation command as a navigation object for each function, a link list buffer is used, and a command priority order is given to pre-commands and post-commands of each function.
By making the number unique to each function, the independence of the navigation command generation process in each function is ensured.

Subsequently, the shaping means 300 performs shaping processing so that the generated navigation commands are in the order of the commands shown in FIGS. 2 and 3. That is,
The shaping unit 300 obtains the navigation object generated by the control program creating unit 200 from the data in the GUI object. Next, based on the navigation object list, the CommandGenerate_A () function of the navigation object is called. CommandGenerate_A ()
The function is CommandGen of the buffer management block.
Call the erate_B () function and set navigation commands in the buffer. At this time, pre,
The post command area is inserted in the linked list buffer by weighting of each function, and the pre and host commands are merged. Next, the navigation command is copied while performing binary conversion to the DVD disc image buffer.

The first title reproducing function will be described. Here, a case where the button 1 on page 1 of the menu 2 is provided with the reproduction function of the title 1 will be described. In the case of the title reproduction function as described above, the ID number of the scene object of the title of the jump destination is stored in the individual information management means. In this case, the jump destination is recorded as the title 1 scene object, and the control program creating means uses this to generate a command as Button1: JumpVTS_TT TTN = 1. This is a command that causes the Button 1 (button 1) to have a function of causing the TTN (title number) in the VTS_TT (VTSTT_VOBS) area to be 1, that is, to jump to the data area of the title 1. In this case, operation is possible with one command.

Next, the second title return function will be described. Here, the button 2 on page 2 of menu 2 is provided with the playback function of title 2, and after playback of title 2, the page returns to page 2 of menu 2 and button 2 is clicked.
A case where a function of highlighting (changing the button color) is provided will be described. In this case, the navigation object shown in FIG. 5 is generated according to the above procedure. FIG. 5 is an example of a navigation object of the title return function.

Here, GP_XX represents a register, and in Button 2 (button 2), register G
Put 0x8001 in P_N0, jump to the post command, evaluate GP_N0 with the post command, and Title
2 (Title 2), and when the reproduction of Title 2 is finished, the value of the register GP_N0 is evaluated and the original menu is returned. In the pre-command of the original menu (Menu2), GP_N0 is evaluated, button 2 is highlighted,
The operation returns to page 2. Incrementing by 1 with the pre and post commands of Title2PGC is a countermeasure for abort processing by the menu call of the remote controller.

Next, the third menu jump function will be described. Here, a case will be described in which the button 1 on page 1 of menu 1 has a function of jumping to page 1 of menu 2 and highlighting button 3 (changing the color of the button). In this case, the navigation object shown in FIG. 6 is generated according to the above procedure. Figure 6
It is an example of a navigation object of the menu jump function created by the program creating device according to the present invention.

This is because in Button1 (button 1), 0x1001 of the register GP_N0 is entered, the post command is jumped, GP_N0 is evaluated by the post command, and jumped to Menu2 (menu 2). In the pre-command of Menu2, GP = N0 is evaluated and HL_BTNN is evaluated.
= 3 (button 3 is highlighted) to jump to page 1.

The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the function that the program creating apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing content can be recorded in a computer-readable recording medium. In order to put the program into the market, for example, a portable recording medium such as a DVD or a CD-ROM in which the program is recorded is sold. It is also possible to store the program in the storage device of the server computer and transfer the program from the server computer to another computer via the network.

The computer executing the program stores the program recorded in the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, the computer can also sequentially execute processing according to the received program each time the program is transferred from the server computer.
