The template 700 defines reproduction areas 710, 720, and 730 of digital items, and events 750, 760, 770, and 780 of a digital item to be executed. The template 700 determines the reproduction area 710 of a ‘video’ digital item, the reproduction area 720 of an ‘audio’ digital item, and the reproduction area 730 of a ‘slide show’ digital item. A digital item related to ‘video’ content is matched to the reproduction area 710, a digital item related to ‘audio’ content is matched to the reproduction area 720, and a digital item related to ‘slide show’ content is matched to the reproduction area 730.
The template 700 defines the ‘move object’ event 750, the ‘set volume’ event 760, the ‘background color’ event 770, and the ‘add digital item’ event 780. The ‘move object’ event 750 defines a function of moving a location of an associated digital item, and the ‘set volume’ event 760 defines a function of setting a reproduction volume of an associated digital item. The ‘background color’ event 770 adjusts a background color of an associated digital item, and the ‘add digital item’ event 780 adds a new digital item to a corresponding template.
For example, when the template 700 associates the reproduction area 710 with the ‘move object’ event 750, the reproduction area 710 moves when the ‘move object’ event 750 is executed.
The application 800 is generated by associating each of the reproduction areas 710, 720, and 730 of the template 700 with a suitable digital item. In other words, a digital item 810 related to a video item is associated with the reproduction area 710, a digital item 820 related to an audio item is associated with the reproduction area 720, and a digital item 830 related to a slide show is associated with the reproduction area 730. Also, a digital item 840 related to an image added by the ‘add digital item’ event 780 may be included in the application 800. By executing reproduction events of the digital items 810, 820, and 830 respectively associated with the reproduction areas 710, 720, and 730, a reproduction event of the application 800 is executed.
In
The area 910 includes information about at least one of resources 912, 914, and 916 for video content, at least one of media resources 922, 924, and 926 for audio content, and at least one of media resources 932, 934, 936, and 938 for image content.
The area 940 includes a media guide 950, a first template 956, a second template 958, and a third template 960. Since the media guide 950 is displayed on a screen in various formats according to a user input, the media guide 950 is regarded as one template, and thus is located on the top of the area 940.
Since the area 970 may include at least one application, the area 970 includes a first application 990, a second application 994, and a third application 996.
The event executer 520 of the apparatus 500 may call a media information interface. As described above, when the media guide 950 is called as the media information interface, the user may execute a ‘search’ event 955 that searches for accessible templates and applications. The media guide 950 accesses the area 940 and the area 970 of the media storage 900 and displays the media guide 950, the first through third templates 956 through 960, and the first through third applications 990 through 996, so that the user can check the accessible templates and applications.
When the user selects the third template 960 in operation 1010, the media guide 950 displays reproduction areas 961, 962, and 963 of digital items, and events 964, 965, 966, and 967.
The user may select and associate a desired digital item with each of the reproduction areas 961, 962, and 963 of the third template 960. For example, the media resource 916 for video content is associated with the reproduction area 961 for video content, the media resource 922 for audio content is associated with the reproduction area 962 for audio content, and the media resources 934 and 936 for image content are associated with the reproduction area 963 for slide show content. The media guide 950 accesses the area 910 of the media storage 900 so that the user may select a desired digital item.
The user may select a desired digital item to execute an event included in the third template 960. For example, the ‘move object’ event 964 may move the location of the reproduction area 961, and the media resource 938 may be associated as a digital item to execute the ‘add digital item’ event 967.
When a signal that editing of the third template 960 is completed is received in operation 1020, a fourth application 980 is generated due to an association relationship between the third template 960 and digital items, and an event setting. When the association relationship and the event set by the user are applied, the fourth application 980 may reproduce video content 981, audio content 982, and a slide show 983. Also, the location of the video content 981 may move, and image content 984 may be further included in the fourth application 980.
Since the fourth application 980 may be inserted into the area 970 of the media storage 900 in operation 1030, the apparatus 500 may publish an application edited by the user.
A media file generated by the apparatus 400 or a media file used in the apparatus 500 may follow a box based file format. Hereinafter, an MPEG-21 file format is referred to as an example of the box based file format. However, the box based file format is not limited to the MPEG-21 file format.
The media file 1100 according to the MPEG-21 file format includes an mdat box 1110 to which a media resource is inserted, and a meta box 1120 to which various pieces of information about the media file 1100 are inserted. Also, the meta box 1120 includes an extensible markup language (XML) box 1128.
If the media file 1100 is generated by the apparatus 400, the meta box 1120 includes a digital item box 1122, a template box 1124, and an application box 1126 in addition to the XML box 1128. A digital item in the digital item box 1122 and a template in the template box 1124 may be associated with an application in the application box 1126, and a digital item in the digital item box 1122, a template in the template box 1124, and an application in the application box 1126 may be associated with information in the XML box 1128.
An XML based syntax 1130 is defined by XML information in the XML box 1128. An example of the XML based syntax 1130 includes an MPEG-21 digital item declaration (MPEG-21 DID). The MPEG-21 file format describes a scene representation 1135 by using the XML based syntax 1130, and an example of the scene representation 1135 includes a lightweight scene representation (LASeR). The media file 1100 is reproduced in operation 1140 by the XML based syntax 1130.
The apparatus 500 calls a media guide so as to execute a media file 1210 in operation 1215. In operation 1220, the media guide is decoded, and then executed. A user may select at least one of a template and an application displayed to be accessible by the media guide.
When the user selects the template in operation 1225, the selected template is decoded in operation 1230. When the user selects a digital item to be associated with the template in operation 1235, a media storage search engine is operated in operation 1240. When editing, such as associating the searched digital item with the template, is completed in operation 1245, an application is generated, and the generated application is published in an area of media storage in operation 1250. After the generated application is published in the media storage, the application may be searched for, or reproduced via the media guide.
When the user selects the application from the media guide in operation 1227, the selected application is decoded in operation 1260. Then, a digital item of the selected application and events of the digital item may be reproduced.
After executing the events about the application or the template, the media guide may be called again, and the user may select media information via the media guide.
A content distributer manufactures a template in such a way that reproducing and editing of content are possible in one apparatus in operation 1310. The content distributer registers the template in a portal server 1320. A content distributer may be an expert developer of the content. For example, the template may be registered in a portal web site in a template content user created content (UCC) format. The template may be registered after being classified according to application categories. For example, a template for a slide show is registered in a slide show category.
General users (users A and B) may access the portal server in operation 1350 or download the template from the portal server in operation 1330. For example, a user may search for the template content UCC registered in the portal web site, and download template content UCC that is most similar to a desired application. An application is generated in operation 1340 when an editing operation is completed by associating the user's media resource with the downloaded template, and completing setting of a related event. When the user registers the generated application in the portal server, another user can download and use the application.
In operation 1410, at least one digital item including identification information of an individual resource is inserted into a media file.
In operation 1420, at least one template including an event for the digital item and execution environment information of the event is inserted into the media file.
In operation 1430, at least one application including association information of the template and the digital item are inserted into the media file.
