Abstract

A method comprises storing real-time multimedia data in a plurality of tracks and/or track subsets; and identifying one or more multi-track groups, each multi-track group being associated with a relationship among one or more of the plurality of tracks and/or track subsets.

Claims

1. A method, comprising:

storing real-time multimedia data in a plurality of tracks and/or track subsets; and

identifying one or more multi-track groups, wherein each multi-track group being identified based at least in part on a relationship among one or more of the plurality of tracks and/or track subsets.

2. The method of claim 1, further comprising:

identifying at least one relation between two or more multi-track groups.

3. The method of claim 1, wherein identifying one or more multi-track groups comprises at least one of:

identifying a multi-track group based on at least one track subset;

grouping multiple tracks and/or track subsets corresponding to multimedia data representative of different views of a scene; and

using a multi-track group box to indicate relations between tracks and/or track subsets.

4. The method of claim 1, further comprising:

forming at least one set of multi-track groups, the set of multi-track groups being associated with one or more characteristic of the multi-track groups.

5. The method of claim 4, wherein forming at least one set of multi-track groups is based at least in part on similar characteristics from a point of view of at least one of multi-view media rendering, coding and capturing.

6. The method of claim 4, wherein forming at least one set of multi-track groups comprises using a multi-track group relation box to indicate relations between multi-track groups.

7. The method of claim 6, wherein one or more criteria are used to indicate relations between multi-track groups.

8. The method of claim 7, wherein a criterion indicates that only one of the multi-track groups is to be processed at one time.

9. A computer program embodied on a computer-readable medium, the computer program comprising computer-executable instructions which when executed by a processor cause the performance of at least the following:

storing real-time multimedia data in a plurality of tracks and/or track subsets; and

identifying one or more multi-track groups, wherein each multi-track group being identified based at least in part on a relationship among one or more of the plurality of tracks and/or track subsets.

10. The computer program of claim 9, wherein the computer-executable instructions which when executed by a processor further cause the performance of:

identifying at least one relation between two or more multi-track groups.

11. The computer program of claim 9, wherein identifying one or more multi-track groups comprises at least one of;

identifying a multi-track group based on at least one track subset,

grouping multiple tracks and/or track subsets corresponding to multimedia data representative of different views of a scene, and

using a multi-track group box to indicate relations between tracks and/or track subsets.

12. The computer program of claim 10, wherein the computer-executable instructions which when executed by a processor further cause the performance of:

forming at least one set of multi-track groups, the set of multi-track groups being associated with one or more characteristic of the multi-track groups.

13. An apparatus, comprising:

a memory for storing real-time multimedia data and comprising computer program code; and

a processor,

the memory and the computer program code configured to, working with the processor, cause the apparatus to perform at least the following;

store real-time multimedia data in a plurality of tracks and/or track subsets; and

identify one or more multi-track groups, wherein each multi-track group being identified based at least in part on a relationship among one or more of the plurality of tracks and/or track subsets.

14. The apparatus of claim 13, wherein the memory and the computer program code configured to, working with the processor, further cause the apparatus to:

identify at least one relation between two or more multi-track groups.

15. The apparatus of claim 13, wherein the memory and the computer program code configured to, working with the processor, further cause the apparatus, in identifying one or more multi-track groups, to at least;

identify a multi-track group based on at least one track subset,

group multiple tracks and/or track subsets corresponding to multimedia data representative of different views of a scene,

use a multi-track group box to indicate relations between tracks and/or track subsets.

16. The apparatus of claim 13, wherein the memory and the computer program code configured to, working with the processor, further cause the apparatus to:

form at least one set of multi-track groups, the set of multi-track groups being associated with one or more characteristic of the multi-track groups.

17. The apparatus of claim 16, wherein forming at least one set of multi-track groups is based at least in part on similar characteristics from multi-view media rendering, coding or capturing point of view.

18. The apparatus of claim 16, wherein forming at least one set of multi-track groups comprises using a multi-track group relation box to indicate relations between multi-track groups.

19. The apparatus of claim 18, wherein one or more criteria being used to indicate relations between multi-track groups.

20. The apparatus of claim 19, wherein a criterion indicates that only one of the multi-track groups to be processed at one time.
