    摘要: A method for encoding a video block using reference blocks comprises assigning the video block to one of first and second prediction groups, and encoding the video block according to a motion compensated prediction encoding mode, using the reference blocks depending on the one of the first and second prediction groups to which the video block is assigned, one of the reference blocks being a decoded block, wherein a first prediction group is obtained by a prediction using the reference blocks belonging to a first prediction group, and a second prediction group is obtained by a prediction using the reference blocks belonging to at least one of the second prediction group and the first prediction group.

    摘要: A video encoding apparatus includes selecting 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.
