    摘要: Provided is a video encoding and decoding method and apparatus. The video encoding method includes selecting a plurality of reference blocks based on a plurality of motion vectors and setting weights assigned to the plurality of reference blocks independently for each of a plurality of regions of a current block in order to predict and encode the current block, thereby providing a new encoding mode allowing accurate prediction of the current block and thus improving the compression rate of video encoding.

    摘要: A method and apparatus are provided for reducing the inter-layer redundancy of a difference signal obtained from an intra-prediction when coding a video using multi-layer structure supporting intra-prediction. The method includes obtaining a first difference block between a block of a first layer and a first prediction block which is used to perform an intra-prediction on the block, obtaining a second difference block between a block of a second layer corresponding to the block of the first layer and a second prediction block which is used to perform an intra-prediction on the block, and obtaining a final difference block between the first difference block and the second difference block.

    摘要: A method and apparatus are provided for improving the compression efficiency of motion vectors of an unsynchronized picture by efficiently predicting the motion vectors using motion vectors of a lower layer. The method compresses motion vectors of an unsynchronized picture belonging to a current layer in a video encoder based on a multilayer having at least the current layer and a lower layer of the current layer. The method includes selecting a base picture for the unsynchronized picture, generating a predicted motion vector of the current layer from a motion vector of the base picture, subtracting the predicted motion vector from a motion vector of the unsynchronized picture, and encoding the result of subtraction.

    摘要: A method and apparatus for extracting a higher quality video stream for a given bit-rate by replacing a specific frame by a base layer frame at a predecoder are provided. A predecoding method performed by the predecoder includes selecting a mode by determining frames to be skipped according to a predetermined criterion among frames located at positions where the base layer exists, and extracting a portion of the bitstream according to the selected mode and extraction conditions.
