Abstract:
A reference picture marking process and a reference picture list management process is handled in a unified reference picture marking and reference picture list management process. A new idle reference picture list may be used for handling reference pictures that are not used for reference in the current picture. Differential coding of picture order count may be used to increase coding efficiency. The reference picture management syntax structure may be sent in the picture parameter set for improved coding efficiency e.g. in regular GOP (group of pictures) arrangements.

Claim (Index 5):
A method for decoding video data, comprising:\n decoding from a bitstream an indication from a syntax element indicative of whether or not a picture is to be used as a reference picture in decoding, decoding an instruction from said syntax element indicative of a reference picture list structure, said reference picture list comprising pictures to be used in decoding a current picture, decoding an idle reference picture list instruction in a syntax element, said idle reference picture list instruction indicative of an idle reference picture list structure, wherein pictures in said idle reference picture list are not used as reference pictures in decoding of the current picture, but are to be used as reference pictures in decoding of another picture than the current picture, wherein the pictures in said idle reference picture list are different than the pictures in the reference picture list, and wherein pictures that are not in said idle reference picture list and not in said reference picture list are marked as unused for reference for any other picture decoded after the current picture, and using said indication and said instruction in handling reference pictures in decoding of video data.
