BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scene including a plurality of objects (for example, a multimedia scene).
The present invention relates to a content editing method for creating / editing a content configured by combining a plurality of Then, the present invention particularly aims to provide a content editing method capable of efficiently performing a link setting for linking another scene to a predetermined object in a predetermined scene at the time of editing.

[0002]

2. Description of the Related Art In recent years, a content creation method is being developed in which a plurality of scenes using a language called a scene description language are combined to create content. HTML (Hyper Text Markup Language) is a typical scene description language. HT
The description of the hypertext document by ML is "<" and ">"
The logical structure of a sentence is expressed by a format specification called a tag surrounded by. The description of the link with other information is made by link information called an anchor. A URL (Uniform Resource Locator) is used to specify the location of the linked information by the anchor. HTML is a language for describing web pages, and it is also possible to embed images, sounds, videos, etc. in the page.

As a scene description language designed to support 3D graphics on the Internet
There is VRML (Virtual Reality Modeling Language). VRM
Even in L, the link can be set by the anchor.

Japanese Unexamined Patent Publication No. 9-138790 "Scenario Editing Device" describes a device that edits contents composed of such a scene description language (script language).

[0005]

[Problems to be Solved by the Invention] Japanese Patent Laid-Open No. 9-138790
In the conventional example described in "Scenario Editing Device", in order to edit the link, the script language is edited,
It is necessary to select and enter the presentation screen name of the transition destination as an attribute of each multimedia data. Therefore, knowledge about the script language is required, or the editor needs to remember the presentation screen name of the transition destination, and the screen transition cannot be visually edited.

In the link setting method in Japanese Patent Laid-Open No. 9-138790, "Scenario Editing Device", a method is used in which the presentation screen being edited is iconized and the transition source screen icon and the transition destination screen icon are connected by an arrow or the like. In general, when the presentation screen being edited is iconized, the screen size is reduced to be iconified. Therefore, in this method, when the transition source screen is composed of multiple objects, it is necessary to set a link for any object, especially an object that has a small occupied area and is difficult to recognize on the icon screen. It is very difficult to do, and when one transition source screen is linked to many transition destination screens, problems such as difficult to see the display occur.

It is an object of the present invention to provide a content editing method capable of efficiently setting a link for linking another scene to a predetermined object in a predetermined scene during editing.

The content to be created consists of two scenes, with the first scene featuring a female and
It is a scene where you are doing PR. Click the star-shaped button in the first scene with the mouse to switch to the second scene. The second scene is a car running. [Outline of Content Creation in Content Editing System] An outline of content creation in this content editing system will be described. In this content editing system, a scene of content is constructed by dragging and dropping the template icon in the template window into the editing window. That is, the template icon can be considered as a component for forming a scene. Details of the template icon will be described later. In the editing window, the scene of the content currently being edited (the scene to be edited) is displayed. [Data Format in this Embodiment] The data structure in this content editing system will be described. Here, it is assumed that they are managed using the MPEG-4 system. The scene structure is BIFS (Binary Format for Scen
It is managed by a scene description language called e). BIFS
Was developed based on VRML and is represented by a tree structure, and the tree is composed of nodes that are its elements. Nodes also have elements called fields to describe their properties.

Each object data is managed by a structure called an object descriptor.
In this object descriptor, the location of the ES of the object data and the information necessary for decoding the ES are described. [Explanation of template window] The template window shows the characteristics of the template icon (scenes that can be added to the scenes displayed in the edit window by dragging and dropping from the template window, functions, etc. are iconified). It is a window in which a plurality of items are listed. The specific state is shown in FIG.

The template window is roughly divided into several tabs according to the characteristics of the template icon, and these tabs can be switched and displayed as needed. Here, a template window in which template icons are listed for each tab of scene description, AV, and button is shown. In this example, two template icons are prepared in the scene description template window, six in the AV template window, and one in the button template window.

First, the AV template window will be described. Scene icons (AV1 to AV6), which are the template icons, are registered as scenes or objects having moving images and sounds. AV1 is an icon of the first scene where a woman is promoting a company, and AV3 is an icon of the scene where a car in scene 2 is running. AV2 and A
V4 to AV6 are not used in the description of this embodiment. The scene icons (AV1 to AV6) also function as scene icons indicating scenes that are link destination candidates, which will be described later.

An is displayed in the scene description template window.
There are chor icon and Group icon. The Anchor icon is a link function designation icon for setting the link function. The Group icon is an icon for grouping, but is not used in this embodiment.

The button template window has a template icon indicating button 1. When this is dragged and dropped into the editing window, buttons are displayed in the scene displayed in the editing window.

FIG. 5 shows a representation of each template icon by a scene description. (A) is a scene description expression of a scene icon AV1 which is a template icon.
Similarly, (b) is a scene description expression of the scene icon AV3. (C) is a scene description expression of the template icon button 1. (D) is a scene description expression of a link function designation icon Anchor which is a template icon.

The ellipses shown in FIG. 5 represent nodes and the rectangles represent fields. Here, URL: ODID = 100 indicates that the object descriptor is associated with an object whose identification ID is 100. That is, the MovieTexture in (a) is associated with the object descriptor whose object descriptor ID is 200, which manages the female moving image object. Similarly, AudioClip is associated with an object descriptor having an object descriptor ID of 100 in which a female voice object is managed. MovieT for (b)
A car video object is associated with the exture, and a car audio object is associated with the AudioClip. The button 1 in (c) has no audio object, and the image texture is associated with a star button that is a still image. U of (d)
An empty RL indicates that it is not yet associated with any object. [Description of Editing Window] The editing window is a window in which the scene being edited is displayed. Clicking on an object in the scene displayed in the edit window puts it in the selected (active) state. When a certain object is selected and the template icon is dragged and dropped into the scene from the template window, the template object acts on the selected object. [Explanation of Scene Tree Window] The scene tree window is a window in which the tree structure of the node of the scene description in the scene being edited is displayed. A node displayed in the scene tree window can be clicked to bring it into the selected state, as in the case of the above-mentioned edit window.

FIG. 6 shows a scene tree window. The node indicated by + in FIG. 6 indicates that there is a child node not displayed below it. A node displayed with-indicates that the child node of the node is displayed. Comments can be entered on the right side of each node. Here, add a comment such as "Top node" to the Layer2D node that is the top node, "Star button" to the Shape node that represents the star-shaped button, and "Woman" to the Group node that represents the female to create a tree structure. The association with the scene is made easy to understand. [Description of Link Creation] Here, a procedure for creating content will be described with reference to FIGS. 7 and 8. FIG. 7 is a flowchart showing the procedure for link setting. Figure 8
Shows the state of link setting on the display screen. FIG. 9 shows a scene description in the procedure of setting a link.

First, when the template icon (AV1) is dragged from the AV template window and dropped into the edit window, the template icon (AV1) is dropped.
1) A woman corresponding to AV1 is displayed on the edit window [Fig. 8 (1)]. In the scene description, the template icon (AV1) shown in FIG. 5A is added below the Layer2D node as shown in FIG. 9A.

Then, when the template icon (button 1) is dragged from the button template window and dropped into the edit window, a star button corresponding to button 1 is displayed on the edit window [Fig.
(2)]. In the scene description, the template icon (button 1) shown in FIG. 5C is added below the Layer2D node as shown in FIG. 9B.

Next, in order to set a link to this star-shaped button, the star-shaped button which is the object (button 1) in the scene displayed in the edit window is clicked to bring it to the selected state [Fig. 8 (3)].

Then, a template icon (Anchor) is dragged from the scene description template window and dropped into the scene displayed in the editing window to set the link function to the star button [Fig. 8
(4)]. In the scene description, as shown in FIG. 9C, an Anchor node is inserted as a parent node of the Shape node which is the highest node of the still image object.

Here, the star-shaped button is added with a link function designated by a template icon (Anchor) which is a link function designation icon, and is grammatically and semantically compatible as a scene description language. It is determined whether or not the object is a linked object, and if it is determined that it is compatible, the link function specification icon (An
Set the link function specified by chor) Next, in order to set the link destination to this star button, drag the template icon (AV3) from the AV template window and drop it in the edit window [Figure 8
(5)]. In the scene description, ODID = 3 indicating the template icon (AV3) is inserted in the URL field of the anchor node as shown in FIG. 9 (d). Here, it is assumed that the ODID of the object descriptor associated with the template icon (AV1) is 3.

Next, a link setting method using the scene tree window will be described. It is assumed that the current scene is displayed in the edit window as shown in FIG. 10, and the scene tree structure showing the scene is displayed in the scene tree window as shown in FIG. here,
With the woman selected in the edit window, the template icon (Anch
If you drag or) and drop it in the edit window, the scene tree structure will be as shown in Figure 12. In addition, although the female object was selected in the edit window, to perform the same operation as this in the scene tree window,
The Group node or Shape node shown in FIG. 11 corresponding to the female object may be selected. And
When a template icon (Anchor) is dragged and dropped in the editing window in the scene description template window, the scene tree structure becomes as shown in FIG. 12 as described above. Here, the Anchor node shown in FIG. 12 is in the selected state.

Next, from the template window shown in FIG.
If a scene icon indicating a male object such as is dragged and dropped, a scene tree structure as shown in FIG. 15 is obtained. Here, the ODID representing the male object is set to 10. The scene tree structure of the scene indicated by the male object is as shown in FIG.

However, if this man does not want to use it as an anchor but wants to display it at the same time as the woman,
Specify the Group node shown in FIG. 12 in the scene tree window and then drag and drop the male object. The scene tree structure in that case is as shown in FIG. In this case, the edit window is displayed as shown in FIG. If you want to specify the link destination for the female object after adding the male object,
After selecting the Anchor node in the scene tree structure of FIG. 16 shown on the scene tree window,
Drag and drop the template icon (AV3) showing the car scene that is the link destination from the template window.

As described above, when the scene tree window is used, it is possible to specify a node that cannot be specified only by specifying an object in the scene displayed on the editing window, and it is possible to realize editing with a higher degree of freedom. [Description of Template Management Unit] The components shown in FIG. 1 will be briefly described. The template management unit 2 manages template icons in the template window. When the user drags and drops the template icon in the template window, the scene description data corresponding to the template icon is sent to the object conformance inspection unit 5. [Description of Object Matching Checking Unit] The object matching checking unit 5 checks whether the scene description data input from the template managing unit 2 is grammatically matched.
If an object in the selected state exists in the scene displayed on the edit window, the scene description data of the selected object and the scene description data input from the template management unit 2 (for example, It is checked whether it matches grammatically with the template icon (link function specification icon) Anchor scene description data in the template window. (For example, whether the selected object is an object that is grammatically and semantically compatible with the scene description language to which the link function designated by the link function designation icon is added. If it matches, the ODID in the scene description is newly reassigned and sent to the scene management unit 6. Also, the ODID of the object descriptor related to the ODID existing in the scene description is changed to the same value. If it does not match, a warning to that effect is displayed and the process ends. [Explanation of Scene Management Unit] The scene management unit 6 synthesizes the scenes according to the input scene description and displays them in the edit window.
