Abstract
This disclosure describes various methods and techniques for decoded picture buffer (DPB) management when multiple decoded layer components with different resolutions need to be stored. In one example, a method of coding video data comprises decoding video data to produce a plurality of decoded layer components, storing the decoded layer components in one or more sub-units of a DPB, and performing a DPB management process on the one or more sub-units, wherein the DPB management process is managed separately for each of the one or more sub-units.
Claims28
A method of coding video data, the method comprising:
- decoding video data to produce a plurality of decoded layer components;
- storing the decoded layer components in one or more sub-units of a decoded picture buffer (DPB);
- and
- performing a DPB management process on the one or more sub-units, wherein the DPB management process is managed separately for each of the one or more sub-units.
An apparatus configured to code video data, the apparatus comprising:
- a video coder configured to:
- decode video data to produce a plurality of decoded layer components;
- store the decoded layer components in one or more sub-units of a decoded picture buffer (DPB);
- and
- perform a DPB management process on the one or more sub-units, wherein the DPB management process is managed separately for each of the one or more sub-units.
An apparatus configured to code video data, the apparatus comprising:
- means for decoding video data to produce a plurality of decoded layer components;
- means for storing the decoded layer components in one or more sub-units of a decoded picture buffer (DPB);
- and
- means for performing a DPB management process on the one or more sub-units, wherein the DPB management process is managed separately for each of the one or more sub-units.
A computer-readable storage medium storing instructions that, when executed, cause one or more processors of a device configured to code video data to:
- decode video data to produce a plurality of decoded layer components;
- store the decoded layer components in one or more sub-units of a decoded picture buffer (DPB);
- and
- perform a DPB management process on the one or more sub-units, wherein the DPB management process is managed separately for each of the one or more sub-units.
