Operation point for carriage of layered hevc bitstream

A device for processing a bitstream including video data, the device comprising:

• a memory to store data extracted from the bitstream;
• and
• one or more processing units configured to:
• extract 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,
• extract 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
• provide the extracted video data to a video decoder.

A computer-readable storage medium having stored thereon instructions that, when executed, cause a processor to:

• extract a descriptor from a bitstream including video data, 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;
