Abstract

A scalable video encoder and decoder has been made. And how to enter Code and decode the corresponding scalable video. A video encoder that can Scalable contains an encoder (100) for encoding blocks in the complementary layer of the image using The parameters in the same auxiliary layer reference weighting are used in the sub-layer reference image to encode. Block in the lower layer of the picture The blocks in the auxiliary layer will correspond to the blocks in the lower layer and the reference images of the auxiliary layer will be. Consistent with the reference image downstairs A scalable video decoder consists of a decoder (200) for decoding blocks in the complementary layer of the image using image weighting parameters. Based on the same auxiliary layer used in the sub-layer reference image to decode the blocks in the lower layers of the image, the blocks in the auxiliary layer correspond to the blocks in the lower layers and the auxiliary layer reference images correspond to the sub-layer reference images.
