DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for editing a multimedia scenario that describes a presentation position, a presentation order, and a presentation effect of multimedia data including a moving image, a sound, a still image, and a text. The present invention relates to a method of changing an apparatus.

[0002]

2. Description of the Related Art In conventional multimedia scenarios, there are a format in which a file name of a media to be presented is stored in a scenario including a path name, and a type in which a media is directly read into a scenario. The former has the advantage that the scenario is treated as an external file, so that the capacity of the scenario is small and the media file displayed in the scenario can be easily changed. On the other hand, the latter method has an advantage in that media data is read into a scenario, so that media management as in the former method is not required, and handling when a scenario is moved to another system becomes easier.

As an example of the former, Japanese Patent Laid-Open No. 4-307675
"Computer display system", JP-A-2-16298
6 “Multimedia information presentation system and multimedia information handling method” and the like.

ctor (Director User's Manual). However, even in the latter case, a method of specifying an external reference is used for a medium having a very large capacity such as a moving image.

[0004]

The former method has a problem that the medium cannot be displayed when the drive configuration is changed or the storage directory name is changed because the external file is referred to. Furthermore, when the scenario becomes huge, it is difficult to understand which media can no longer be referred to.

[0005] On the other hand, the latter method has a problem that the scenario file becomes large because the medium is read, the memory is squeezed, and the processing performance decreases. Further, in the latter case, when the medium is changed or modified, the work is extremely complicated.

Therefore, when the scenario execution performance is good and the media is frequently modified, the former method is effective, but there is a need for a method that can easily realize the path management and change of the reference medium. Was.

For example, in the former method, a medium is specified by a file name and a path name. A path name has a relative path and an absolute path specification. The relative path specification is a method of describing a relative path from a directory in which a scenario is set. The absolute path specification is a path specification from a root directory. Here, when specifying a medium in a different drive, the absolute path must be specified.

Here, when a large number of media of different drives are specified in the scenario, the absolute path is specified. Therefore, when the drive configuration is changed, the path change processing for each medium in the scenario is performed for each medium. It has to be processed, which is a very complicated task.

That is, even if a drive or a path is changed, no function has been provided so that the scenario can be changed collectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.

First, an embodiment of a scenario to be edited in the present invention will be described. The scenario targeted by the present invention can be managed in units called media and nodes as shown in FIG. The scenario holds a node management list, and holds pointers to the nodes included in the scenario. The media is an object that manages the presentation of media data, and specifies the presentation position, presentation timing, presentation effect, and the like of the media. On the other hand, the node designates how to present a plurality of media on the screen, and describes the hierarchical relationship when media data is overlapped, the order of presentation, the order of erasure, and the like. A scenario in which such nodes are linked by a hyperlink is a scenario. The hyperlink description can be set as one attribute of the media.

The medium holds the file name of the content to be presented or a pointer to the storage location of the content, and holds the effect, presentation size, and presentation position when media data is presented. Further, when there is a link, the link destination information, the link activation condition, and the like are held.

On the other hand, the node manages the media held by the node in a media management table. The media management table includes a media stacking order list, a presentation order list,
It is composed of an erasure order list, holds the vertical relationship of the overlapping display at the time of media presentation, the order of presentation, and the order of erasure, and refers to the pointer to the media held by the node.

The above-described scenario is only an example, and the management place of the attribute may be changed.

FIG. 1 shows an example of the configuration of a path changing apparatus for a multimedia scenario according to the present embodiment. In FIG. 1, the path changing device includes a file input / output management unit 10.
, Display management means 11, input management means 12, scenario storage means 13, path edit management means 14, and path storage means 15.

The file input / output management unit 10 is a unit for reading / writing a scenario file to be edited and searching for a media file.

The display management means 11 is a means for processing the display of menus, dialog boxes and the like.

The input management means 12 converts a signal from a mouse or a keyboard into a command and transmits the command to the path edit management means 14.

The scenario storage means 13 is a means for storing a scenario for changing a path on a memory.

The path edit management means 14 is a means for managing the path change processing. The path edit management unit 14 receives a path change end command, a path designation command, a path change command, a scenario read command, and a scenario save command from the input management unit. The operation of the path editing management means 14 will be described later.

The path storage means 15 internally stores a path table. The path table includes a path name and a media table name as shown in FIG. The media table contains the media name, the file name included in the path,
This is a table that holds a flag (file confirmation flag) indicating whether a file exists. The file confirmation flag holds two states, that is, no file and a file.

FIG. 5 shows an embodiment of the editing user interface of the path changing device according to the present invention. FIG.
Indicates a state in which LIST1 of the path list in FIG. 3 is displayed. In FIG. 5, reference numeral 51 denotes a path list display control for displaying a path name of the path list, and a path name to be changed can be selected with a mouse. Reference numeral 52 denotes a text editing control for editing / changing the path name highlighted in the path list display control 51.
If you change the path name displayed in this control,
The highlighted part of the path list display control 51 and the corresponding path name in the path list are also changed. Reference numeral 53 denotes a control for displaying media included in the selected path in a list format. Reference numeral 54 denotes a reference button for displaying a file selection dialog for browsing a path. The path name specified in the file selection dialog is written to the text editing control 52. Reference numeral 55 denotes an edit end button. The completion of the change of the path name is notified to the path edit management unit 14. Reference numeral 56 denotes a cancel button for canceling editing. Numeral 57 indicates the state of the file confirmation flag. A circle indicates that the file exists, and a cross indicates that the file does not exist.

[0024] The file selection dialog is Micors
Windows 3.1 (Microsoft)
A dialog prepared by the OS such as the Windows 3.1 User's Guide is used. Select the path,
When the file selection dialog is completed, the path name on the text editing control 52 is changed to the selected path name.

When the mouse is clicked on each control, the input management means 12 is notified. Input management means 12
Determines the control from the place where the mouse button is pressed, and sends the corresponding command to the path editing management means 14.

For example, when the input management means 12 selects the path list display control 51 with a mouse,
The input management means 12 sends a path selection command to the path edit management means 14. When the edit end button 55 is selected,
Send path change command. When the path name is changed on the text editing control 52, a path change command is sent. Similarly, by activating the reference button 54 to display a file selection dialog and to select a path name, a file path change command can be sent. When the editing end button 55 is pressed, a path change end command is sent. When the cancel 56 is pressed, an editing stop command is sent, and the editing is canceled.

Next, the operation of the path editing management means 14 will be described with reference to the drawings. FIG. 4 shows the path editing management means 1.
14 is a flowchart illustrating a path change operation of No. 4; When the apparatus is started, a file selection dialog is displayed (step 40), a scenario to be changed is selected (step 41), the file selection dialog is closed (step 42), and the selected scenario is read into the scenario storage unit 13 (step 40). Step 43). Next, the scenario storage means 13
The medium inside is searched (step 44). If all media are not searched, the media path name and file name are separated and stored in the path storage unit 15 (step 4).
5). If there is no path name having the same name as the separated path name in the path table in the path storage means 15, a new path name is added (steps 46 and 47). The media name and the file name are added to the media table referred to by the path table (step 48). Next, it is confirmed through the file input / output means 10 whether the added file exists in the designated path (step 49). The result of the file presence check is set in the file check flag (step 41).
0). Here, if there is a file, "file exists" is set, and if there is no file, "no file" is set. After step 410 ends, the process returns to step 44. When the processing is completed for all the media in step 44, a path change dialog box is displayed on the display management means 11 (step 411). When the path name is changed and a path change command is received (step 412), the file input / output means 10 is checked to see if a file in the media list exists in the changed path (step 413). The presence or absence of the file is set in the file confirmation flag of the path storage unit 15 (step 414). Thereafter, the display of the file confirmation flag display control 57 is changed, and the process returns to step 412 (step 415). If an editing stop command is received in step 412, the process ends (step 416). In the case of the path change end command (step 417), the contents of the change in the path storage means 15 are recorded in the scenario storage means 13 (step 418), and the processing ends.

It is easy to incorporate the apparatus of the present invention into a conventional multimedia scenario editing system, multimedia scenario presentation system, or the like. In these integrated systems, this device is started when the scenario is read,
It is also possible to change the path and the like.

[0029]

According to the present invention, even if the storage location (drive or path) of the multimedia data specified in the scenario is changed, it can be changed collectively, so that the path name of the media can be changed as in the prior art. There is no need to change each one.

Further, by preparing a file having the same name with different contents for each different directory and changing the path name, it is possible to easily create applications having different contents in a common scenario.

Further, the medium whose file name cannot be referenced due to the change of the directory name is displayed as "no medium", so that it is easy to determine which path name is to be changed. As a result, media not included in the path can be easily identified. The apparatus described above can be easily added to a conventional scenario editing apparatus, for example, a scenario editing apparatus described in JP-A-3-41573 "Data editing method and apparatus".
