Abstract
A video decoder is configured to remove pictures from a decoded picture buffer based on the value of an explicitly coded syntax element. A video decoder may be configured to decode a syntax element indicating a picture to remove from a decoded picture buffer, and remove the first picture from the DPB. The video decoder may then decode a current picture, and store the decoded current picture in the DPB.
Claims30
A method of decoding video data, the method comprising:
- decoding a first syntax element indicating a first picture to remove from a decoded picture buffer (DPB);
- removing the first picture from the DPB;
- decoding a current picture;
- and
- storing the decoded current picture in the DPB.
A device configured to decode video data, the device comprising:
- a memory configured to store video data;
- and
- one or more processors implemented in circuitry and in communication with the memory, the one or more processors configured to:
- decode a first syntax element indicating a first picture to remove from a decoded picture buffer (DPB);
- remove the first picture from the DPB;
- decode a current picture;
- and
- store the decoded current picture in the DPB.
A device configured to decode video data, the device comprising:
- means for decoding a first syntax element indicating a first picture to remove from a decoded picture buffer (DPB);
- means for removing the first picture from the DPB;
- means for decoding a current picture;
- and
- means for storing the decoded current picture in the DPB.
A non-transitory computer-readable medium storing instructions that, when executed, causes one or more processors configured to decode video data to:
- decode a first syntax element indicating a first picture to remove from a decoded picture buffer (DPB);
- remove the first picture from the DPB;
- decode a current picture;
- and
- store the decoded current picture in the DPB.
