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

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.
