Tracking a reference picture on an electronic device
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.
1. A system comprising:
a computer-readable medium storing a bitstream comprising encoded picture data; and
one or more decoder processors that are configured to decode the encoded picture data by performing operations comprising:
accessing the bitstream;
decoding a portion of the bitstream to produce a decoded reference picture;
tracking the decoded reference picture in a decoded picture buffer (DPB) with reduced overhead referencing based on a designated picture, wherein the tracking is based on a signaled wrap indicator, wherein the wrap indicator indicates a transition between two sets of pictures, and wherein the wrap indicator causes modification of a cycle parameter for one or more of the two sets of pictures; and
decoding a picture based on the decoded reference picture.
2. The system of claim 1 , wherein the wrap indicator is signaled when a picture order count (POC) numbering transitions from one set of pictures to the next set of pictures.
3. The system of claim 2 , wherein the POC numbering transitions from one [0, . . . , MaxPOC-1] set of pictures to the next set of pictures, and wherein MaxPOC corresponds to a maximum value of the POC used to decode the encoded picture data.
