Abstract

A media information processing method includes obtaining sub-bitstream data, where the sub-bitstream data includes indication information, and the indication information is used to indicate an amount of tile data included in the sub-bitstream data, or the indication information is used to indicate whether the sub-bitstream data can be used for splicing, and processing the sub-bitstream data based on the indication information.

First claim

What is claimed is:

1. A media information processing method, comprising:
obtaining sub-bitstream data, wherein the sub-bitstream data comprises indication information, and wherein the indication information indicates an amount of tile data comprised in the sub-bitstream data or indicates whether the sub-bitstream data can be used for splicing; and
processing the sub-bitstream data based on the indication information.

2. The media information processing method of claim 1 , wherein the sub-bitstream data comprise supplementary enhancement information (SEI), and wherein the SEI carries the indication information.

3. The media information processing method of claim 1 , wherein a box of a track carries the indication information.

4. The media information processing method of claim 1 , wherein a sample entry type of a track carries the indication information.

5. The media information processing method of claim 1 , wherein a media presentation description (MPD) file carries the indication information.

6. The media information processing method of claim 1 , wherein the sub-bitstream data further comprises video parameter set (VPS) information, and wherein the media information processing method further comprises further processing the sub-bitstream data based on the VPS information.

7. The media information processing method of claim 1 , wherein the sub-bitstream data further comprises sequence parameter set (SPS) information, and wherein the media information processing method further comprises further processing the sub-bitstream data based on the SPS information.

8. The media information processing method of claim 1 , wherein the sub-bitstream data further comprises picture parameter set (PPS) information, and wherein the media information processing method further comprises processing the sub-bitstream data based on the indication information and the PPS information.

9. The media information processing method of claim 1 , wherein the sub-bitstream data further comprises slice segment (SS) information, and wherein the media information processing method further comprises further processing the sub-bitstream data based on the SS information.

10. A media information processing method, comprising:
obtaining sub-bitstream data of an original image, wherein the sub-bitstream data comprises tile data;
determining indication information of the sub-bitstream based on an amount of the tile data, wherein the indication information indicates the amount or indicates whether the sub-bitstream data can be used for splicing; and
sending the sub-bitstream data to a terminal,
wherein the sub-bitstream data comprises the indication information.

11. A media information processing apparatus, comprising:
a receiver configured to obtain sub-bitstream data, wherein the sub-bitstream data comprises indication information, and wherein the indication information indicates an amount of tile data comprised in the sub-bitstream data or indicates whether the sub-bitstream data can be used for splicing; and
a processor coupled to the receiver and configured to process the sub-bitstream data based on the indication information.

12. The media information processing apparatus of claim 11 , wherein the sub-bitstream data comprise supplementary enhancement information (SEI), and wherein the SEI carries the indication information.

13. The media information processing apparatus of claim 11 , wherein a box of a track carries the indication information.

14. The media information processing apparatus of claim 11 , wherein a sample entry type of a track carries the indication information.

15. The media information processing apparatus of claim 11 , wherein a media presentation description (MPD) file carries the indication information.

16. The media information processing apparatus of claim 11 , wherein the sub-bitstream data further comprises video parameter set (VPS) information, and wherein the processor is further configured to process the sub-bitstream data based on the VPS information.

17. The media information processing apparatus of claim 11 , wherein the sub-bitstream data further comprises sequence parameter set (SPS) information, and wherein the processor is further configured to process the sub-bitstream data based on the SPS information.

18. The media information processing apparatus of claim 11 , wherein the sub-bitstream data further comprises picture parameter set (PPS) information, and wherein the processor is further configured to process the sub-bitstream data based on the PPS information.

19. The media information processing apparatus of claim 11 , wherein the sub-bitstream data further comprises slice segment (SS) information, and wherein the processor is further configured to process the sub-bitstream data based on the SS information.

20. A media information processing apparatus, comprising:
a receiver configured to obtain sub-bitstream data of an original image, wherein the sub-bitstream data comprises tile data;
a processor coupled to the receiver and configured to determine indication information of the sub-bitstream based on an amount of the tile data, wherein the indication information indicates the amount or indicates whether the sub-bitstream data can be used for splicing; and
a transmitter coupled to the processor and configured to send the sub-bitstream data to a terminal,
wherein the sub-bitstream data comprises the indication information.
