<p>In the encoding of video data, a list of references pictures is constructed to be used in decoding. Prediction (direction) modes are defined by n -tuples ( x 0 , x 1 ,..., x M-1 ), where x m specifies prediction option of the m -th component of the motion vector field, m =0,.., M -1, where M components to the motion fields exist; where a coding option x m 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 "/", x m ˆˆ {"/",0, 1, ..., r m -1}; where option "/" specifies that the component is not used, and other options 0, 1, ..., r m -1 specify one of r m combinations. A subset of all possible n -tuples is provided and a prediction mode used for predicting an inter-coded block is defined by reference to that subset.</p> |
