Absolute or Explicit Reference Picture Signaling

摘要

An encoded representation of a picture of a video stream is decoded by retrieving buffer description information identifying a buffer description defining multiple reference pictures of the video stream from the encoded representation. A picture identifier of a reference picture is determined based on picture identifier information retrieved from the buffer description for the reference picture and a reference picture preceding the reference picture according to a list order in the buffer description. The determined picture identifier is used to update a decoded picture buffer that stores reference pictures to be used as decoding reference for the picture and/or any subsequent picture of the video stream.

主权项

1. A method of decoding an encoded representation of a current picture of a video stream of multiple pictures, said method comprising:
retrieving, from said encoded representation of said current picture, a buffer description defining multiple reference pictures independent of encoded representations of previous pictures; determining a picture identifier identifying a reference picture of said multiple reference pictures based on picture identifier information retrieved from said buffer description for said reference picture and picture identifier information retrieved from said buffer description for a reference picture preceding said reference picture according to a list order in said buffer description; and updating a decoded picture buffer based on the determined picture identifier.
