Abstract
Encoding and decoding is accomplished herein using a multi-reference picture buffer. Reference frames are assigned to reference picture buffers when used for encoding and are identified with picture IDs unique relative to other picture IDs currently associated with the reference picture buffers. The maximum picture number used as the picture ID can be based on a number of reference picture buffers available to encode and decode the frames plus a value based on an expected error rate. The picture IDs can be assigned based on a least recently used policy. When a reference frame is no longer needed for encoding and decoding, a picture ID number associated with the reference frame can be released for re-assignment to a new reference frame.
