Abstract

A method for transmitting scene composition information from an apparatus therefor in a multimedia communication system is provided. The method includes generating scene composition information comprising media attributes information and temporal information, and transmitting the scene composition information, wherein the media attributes information and temporal information is separated into different formats.

First claim

The invention claimed is:

1. A method of transmitting scene composition information in a multimedia system, the method comprising:
generating scene composition information comprising a list of asset (LoA) which includes media data type information for a plurality of scenes and spatial and temporal information of asset (STIA) which includes spatial and temporal information related to each of a plurality of scenes and spatial and temporal information related to each of a plurality of areas composing a scene of the plurality of scenes; and
transmitting the scene composition information,
wherein the LoA indicates asset information of all assets composing the plurality of scenes, and
wherein the spatial and temporal information related to the plurality of scenes represents that the plurality of scenes is activated in series based on a time axis, and the plurality of areas included in the scene is activated in parallel based on the time axis.

2. The method of claim 1 , wherein types of an asset included in each of the plurality of areas are different from each other.

3. The method of claim 1 , wherein media data type information for initialization is acquired by analyzing the LoA.

4. The method of claim 1 ,
wherein the media data type information comprises an address of a media source, and
wherein the spatial and temporal information related to each of the plurality of areas comprises at least one of a type or a format of media.

5. A non-transitory computer-readable storage medium storing instructions that, when executed, cause at least one processor to perform the method of claim 1 .

6. The method of claim 1 , wherein the LoA is separately described from the STIA in the scene composition information.

7. A method of receiving scene composition information in a multimedia system, the method comprising:
receiving scene composition information comprising a list of asset (LoA) which includes media data type information for a plurality of scenes and spatial and temporal information of asset (STIA) which includes spatial and temporal information related to each of a plurality of scenes and spatial and temporal information related to each of a plurality of areas composing a scene of the plurality of scenes; and
displaying a scene using the scene composition information,
wherein the LoA indicates asset information of all assets composing the plurality of scenes, and
wherein the spatial and temporal information related to the plurality of scenes represents that the plurality of scenes is activated in series based on a time axis, and the plurality of areas included in the scene is activated in parallel based on the time axis.

8. The method of claim 7 , wherein types of an asset included in each of the plurality of areas are different from each other.

9. The method of claim 7 , wherein media data type information for initialization is acquired by analyzing the LoA.

10. The method of claim 7 ,
wherein the media data type information comprises an address of a media source, and
wherein the spatial and temporal information related to each of the plurality of areas comprises at least one of a type or a format of media.

11. A device for transmitting scene composition information in a multimedia system, the device comprising:
at least one processor configured to generate scene composition information comprising a list of asset (LoA) which includes media data type information for a plurality of scenes and spatial and temporal information of asset (STIA) which includes spatial and temporal information related to each of a plurality of scenes and spatial and temporal information related to each of a plurality of areas composing a scene of the plurality of scenes; and
a transmitter configured to transmit the scene composition information,
wherein the LoA indicates asset information of all assets composing the plurality of scenes, and
wherein the spatial and temporal information related to the plurality of scenes represents that the plurality of scenes is activated in series based on a time axis, and the plurality of areas included in the scene is activated in parallel based on the time axis.

12. The device of claim 11 , wherein types of an asset included in each of the plurality of areas are different from each other.

13. The device of claim 11 , wherein media data type information for initialization is acquired by analyzing the LoA.

14. The device of claim 11 ,
wherein the media data type information comprises an address of a media source, and
wherein the spatial and temporal information related to each of the plurality of areas comprises at least one of a type or a format of media.

15. A device for receiving scene composition information in a multimedia communication system, the device comprising:
a receiver configured to receive scene composition information comprising a list of asset (LoA) which includes media data type information for a plurality of scenes and spatial and temporal information of asset (STIA) which includes spatial and temporal information related to each of a plurality of scenes and spatial and temporal information related to each of a plurality of areas composing a scene of the plurality of scenes; and
at least one processor configured to control a display of a scene using the scene composition information,
wherein the LoA indicates asset information of all assets composing the plurality of scenes, and
wherein the spatial and temporal information related to the plurality of scenes represents that the plurality of scenes is activated in series based on a time axis, and the plurality of areas included in the scene is activated in parallel based on the time axis.

16. The device of claim 15 , wherein types of an asset included in the plurality of areas are different from each other.

17. The device of claim 15 , wherein media data type information for initialization is acquired by analyzing the LoA.

18. The device of claim 15 ,
wherein the media data type information comprises an address of a media source, and
wherein the spatial and temporal information related to each of the plurality of areas comprises at least one of a type or a format of media.

19. The device of claim 15 , wherein the LoA is separately described from the STIA in the scene composition information.
