Abstract

A method of encoding a video signal representing a sequence of pictures, the method employing both non-temporal prediction and temporal prediction, wherein the method comprises, for each picture that forms a reference picture for the temporal prediction of another picture, associating with each such picture an indicator indicating the temporal order of the reference picture in the encoded video signal relative to the other reference pictures in the encoded video signal.

Claims

1. A method of encoding a video signal representing a sequence of pictures to form an encoded video signal comprising temporally independent INTRA pictures and temporally predicted pictures, wherein INTRA pictures and at least some of the temporally predicted pictures are used to form reference pictures for the temporal prediction of other pictures in the video sequence, comprising indicating an encoding order of those pictures used to form reference pictures in the encoded video signal with a sequence indicator having an independent numbering scheme, such that consecutive pictures used to form reference pictures in encoding order are assigned sequence indicator values that differ with respect to each other by a predetermined amount independent of the number of non-reference pictures encoded between successive reference pictures.
