OPERATION POINT FOR CARRIAGE OF LAYERED HEVC BITSTREAM |
| 摘要 |
A device for processing a bitstream including video data, such as a demultiplexer, extracts a descriptor from the bitstream, wherein the bitstream includes layers of video data for operation points, separate from the descriptor, such that each operation point includes one or more of the layers of video data, and wherein the descriptor includes a set of profile, tier, and level (PTL) structures and data that associates each of the layers of each of the operation points with a corresponding one of the PTL structures, extracts video data for one of the operation points from the bitstream based at least in part on the PTL structures to which the layers of the one of the operation points correspond, and provides the extracted video data to a video decoder. |

1. A method of processing a bitstream including video data, the method comprising:
extracting a descriptor from the bitstream, wherein the bitstream includes layers of video data for operation points, separate from the descriptor, such that each operation point includes one or more of the layers of video data, and wherein the descriptor includes a set of profile, tier, and level (PTL) structures and data that associates each of the layers of each of the operation points with a corresponding one of the PTL structures; extracting video data for one of the operation points from the bitstream based at least in part on the PTL structures to which the layers of the one of the operation points correspond; and providing the extracted video data to a video decoder. |
