Video encoding and decoding using reference pictures

摘要

A method of encoding of video data using motion compensated motion prediction whereby a list of references pictures is initially constructed to be used in decoding. Prediction (direction) modes are defined by constructing n-tuples, each tuple containing M prediction options Xm, where each prediction Xm is an element from a set composed of all defined combinations of motion prediction modes and reference picture indices with the addition of an option I specifying that a component is not to be used. A subset T of all possible n-tuples is provided and a prediction mode used for predicting an inter-coded block is defined by reference to a said n-tuple. Also disclosed is a method for decoding video data using motion compensated motion prediction by construction a subset of T of all possible n-tuples.
