[0004] An example of a video / video editing system in which a television program is produced by an interactive operation between a user and a computer is described in Toshiaki Yokoyama et al., "Program Creation / Interactive Editing System Based on the TV Program Description Language TVML", No. 3. "Information Media Symposium", December 1997, and Toshiaki Yokoyama et al., "Development of TVML Machine Interface for TVML", Electronic Information Society Conference, September 1997.

[0005] An example of an editing screen of the video data editing system disclosed in the above document will be described with reference to FIG. FIG. 3 shows a basic editing screen displayed on the monitor. 201 is an editing window, 202 and 202 'are studio blocks, 203 is a movie block, 204 is a title block, 205 is a superimposed character block, 206 is a sound block, 2
07 is a narration block, 208 is various setting blocks, 2
09 is an event mark, 210 is a dialogue setting section, 211 is an operation setting section, 212 is a camera work setting section, 214 is another setting section,
213 and 213 'are scroll bars, 215 is a start block, and 11 and 12 are representative screens.

In the editing window 201, a studio block 202, a movie block 203, a title block 204, a studio block 202 ', and the like are arranged on the left side of the screen of the editing window 201, and these are video data output to a television screen. Is shown. In the editing window 201, the vertical axis is the time axis, and television programs to be broadcast in order from the top to the bottom of the screen are generated.

For example, in the television program having the configuration shown in FIG. 3, a studio block 202, a movie block 203, a title block 204, and a studio block 202 'continue in order from the bottom of a start block 215 in which "start" is drawn. Therefore, in this case, first, the events generated for the CG character, camera work, and studio set (props, props, and background) in the CG studio are broadcast in the order of the event mark 209, and then the “dog” A moving image of "disappearance scene (day)" will be broadcast, then the title will be displayed in characters, and a CG studio scene will be broadcast. Of course, the order and the combination differ depending on the contents of the program to be broadcast.

The studio block 202 includes a dialogue setting section 210 for causing a CG character to speak (setting the dialogue, voice, and quality of the CG character) in the CG studio, and walking (setting the arrangement and operation of the CG character). Operation setting section
211, a camera work setting unit 212 for specifying a camera work,
In addition, CG studio background and studio set props,
Various program-related information such as the setting section 214 for setting props and their combinations is set. The studio block 202 displays various video data information set for each event, that is, CG studio set information, CG character dialogue and movement, and camera work information. The movie block 203 is a part for performing reproduction control settings of an edited moving image prepared in advance, and displays a file name of the moving image and other information. For example, by clicking the representative screen 11 on the left side of the movie block 203 with the mouse of the input device, a movie setting window (not shown) is popped up on the editing screen, and the editing / setting operation of the movie setting window causes

As mentioned above, the studio block 20
2 includes a dialogue setting unit 210 for setting dialogue of the CG character, and an operation setting unit 21 for setting the movement of the CG character and the like.
1. There is a camera work setting unit 212 for setting camera work in the studio. Each block of the studio block 202, the movie block 203, and the title block 204 is decomposed in the vertical direction (time axis order) into several units called events. It is displayed with mark 209. The creator of the TV program (hereinafter referred to as the creator) uses the GUI on the edit screen in FIG.
Produce a TV program by operation. First, the creator causes the editing window 201 to generate a studio block 202, a movie block 203, a title block 204, and the like in accordance with the scene of the program to be produced, and arranges the blocks in the order of progress (elapse) of the program. Then, a program is produced by making detailed various settings in each block. Hereinafter, an example of the setting in the studio block 202 will be described. Basically, all settings such as dialogue and movement of a CG character can be set only once at the corresponding location of one event. That is, when the studio block 202 is generated and arranged on the editing screen, only one event is generated in the studio block 202. The event here indicates the content of one line in the horizontal direction of the screen displayed on the event mark 209 in FIG. Usually, the studio block 202 requires multiple events, and when the creator specifies the addition of an event, a new event is added to the studio block 202, and the studio block 202 extends vertically and the screen is lower than the block. Blocks in the direction (for example, after the movie block 203) are shifted downward by one event. After adding an event to each block as described above, various settings of the event are performed. For example, the line of the character is input in the line of the line in the studio block 202. Now, when a dog appears as a CG and the dog performs a barking operation, a bark is input in the dialog box 210 of the studio block 202, and a barking operation is input in the operation column 211 of the same line, In column 212, camera work information of the scene is input, and in the other column 214, a set of studios (props, props,
Background) is input. Further, necessary information is similarly input to the superimposed character block 205, sound block 206, narration block 207, and various setting blocks 208 on the same line. In addition, information unnecessary to the event is not input to each of these blocks, so that the blocks may be blank. A TV program is produced by the above operations. Here, as described above, the scroll bar 213 increases the event of each block, and the display is the window 201.
Used to move the display by operating with a mouse or the like when not all are displayed. Edit window 201
Is displayed in a smaller area than the monitor screen,
The display can be moved up, down, left and right using the scroll bars 213, 213 '.

[0011] The television program thus produced is
The confirmation is performed on a display screen as shown in FIG. FIG. 4 shows another example of the edit screen displayed on the monitor. 201
Is an edit window, 301 is a preview window, 302 is a play button, and shows that the preview window 301 has been pop-up displayed on the edit window 201. By clicking the play button 302 of the preview window 301 with the mouse of the input device,
The produced television programs are generated one after another and displayed in the order of the broadcast time sequence of the scenario. The video displayed in the preview window 301 is the video that is actually broadcast on television.

In addition to the purpose of directly producing a program, a studio set can be realized in a virtual space.
A simulation before actually producing a program can be easily performed without using an actual camera, studio set, props, props, actors, extras, and the like. Further, it can be used not only for broadcasting programs and video programs, but also for producing materials for presentations and demonstrations such as conferences and presentations.

As described above, the number of events increases as the program editing / production work progresses, and accordingly, the size of one block to be displayed gradually increases and extends in the vertical direction. The lower block on the screen cannot be displayed on the monitor due to the restriction of the resolution of the monitor screen. In this case, when the creator of the TV program wants to display on the screen a block that has protruded to the lower side of the screen, the user can change the display content of the window while operating the scroll bar 213 (FIG. 3) on the right side of the edit window 201 with the mouse. The content of the production must be confirmed by scrolling, and the operation becomes complicated, and the content cannot be grasped at once.

[0014]

As described above, the above-described prior art displays video data on a screen and uses a GUI.
When editing the video data on the screen, it is necessary to check while operating the scroll bar with the mouse to find the necessary part of the video data, which makes the operation complicated and difficult to grasp the contents There was a disadvantage of becoming.

SUMMARY OF THE INVENTION An object of the present invention is to provide a video data editing method which eliminates the above-mentioned drawbacks, has a simple search for contents, and has an editing screen which is easy to confirm.
