INTER-VIEW RESIDUAL PREDICTION IN MULTI-VIEW OR 3-DIMENSIONAL VIDEO CODING

摘要

A video coder scales a motion vector of a current prediction unit (PU) of a current picture in order to compensate for a difference in temporal distance. In addition, the video coder determines a predictive block for the current PU, determines a disparity reference block based on samples of the disparity reference picture at a location indicated by a disparity vector of the current PU, and determines, based on samples of the fixed reference picture at a location indicated by the scaled motion vector, a temporal-disparity reference block for the current PU. The video coder then determines a residual predictor for the current PU. Each sample of the residual predictor for the current PU indicates a difference between a sample of the temporal-disparity reference block for the current PU and a corresponding sample of the disparity reference block.
