Abstract
A method for tracking a reference picture on an electronic device is described. The method includes receiving a bitstream. The method also includes decoding a portion of the bitstream to produce a decoded reference picture. The method further includes tracking the decoded reference picture in a decoded picture buffer (DPB) with reduced overhead referencing. The method additionally includes decoding a picture based on the decoded reference picture.
Claims5
A method for decoding video bitstream comprising:
- receiving a buffer description of decoded reference pictures from said bitstream, wherein said buffer description includes a poc cycle parameter for one or more long term reference pictures, and said poc cycle parameter is used to calculate a picture order count (POC) for said decoded long term reference pictures;
- identifying said decoded reference pictures of a current picture from a decoded picture buffer, based on said poc cycle parameter;
- decoding said current picture using inter-frame prediction based on said decoded reference pictures;
- and
- buffering said decoded picture in said decoded picture buffer for prediction, wherein said identifying uses said poc cycle parameter to calculate at least a part of references for said decoded reference pictures.

An electronic device configured for decoding video bitstream, comprising:
- a processor being executable to:
- receive a buffer description of decoded reference pictures from said bitstream, wherein said buffer description includes a poc cycle parameter for one or more long term reference pictures, and said poc cycle parameter is used to calculate a picture order count (POC) for said decoded long term reference pictures;
- identify said decoded reference pictures of a current picture from a decoded picture buffer, based on said poc cycle parameter;
- decode said current picture using inter-frame prediction based on said decoded reference pictures;
- and
- buffer said decoded picture in said decoded picture buffer for prediction, wherein said poc cycle parameter is used to calculate at least a part of references for said decoded reference pictures.
