Encoding the predictive error signal, information of the motion vector, and index information indicating the selected combination is included. | 2010-11-04 |
20100278243 | VIDEO ENCODING/DECODING METHOD AND APPARATUS FOR MOTION COMPENSATION PREDICTION - A video encoding method and apparatus to select one combination, for each block of an input video signal, from a plurality of combinations. Each combination includes a predictive parameter and at least one reference picture number determined in advance for the reference picture. A prediction picture signal is generated in accordance with the reference picture number and predictive parameter of the selected combination. A predictive error signal is generated representing an error between the input video signal and the prediction picture signal. Encoding the predictive error signal, information of the motion vector, and index information indicating the selected combination is included. | 2010-11-04 |
