    摘要: A motion compensation method and apparatus that sequentially use global motion compensation and local motion compensation, a video decoding method, a video encoder, and a video decoder are provided. The motion compensation method includes extracting global motion information of a reference block, performing global motion compensation by applying the extracted global motion information to the reference block, extracting local motion information of the global motion-compensated reference block, and performing local motion compensation by applying the local motion information to the global motion-compensated reference block.

    摘要: Provided are an encoding and decoding method and an apparatus for implementing the same in which a processing order for predetermined-size blocks included in a macroblock is defined in order to efficiently use spatial correlation in an image. After a macroblock is divided into first blocks of a predetermined size and motion compensation is performed on each of the first blocks, a second-block processing order for sequentially processing second blocks included in a current first block is determined in order to process a residue between a motion compensation value of the current first block and the current first block in units of the second blocks having a smaller size than that of the current first block.

    摘要: A method of assigning a priority for controlling a bit rate of a bitstream having a plurality of quality layers is provided. The method includes composing first quality layers for a reference picture, composing second quality layers for a current picture that is encoded with reference to the reference picture, and assigning a priority each of the first and second quality layers, wherein a low priority is assigned to a quality layer having a small influence on a video quality reduction of the current picture when the quality layer is truncated.

    摘要: Deblocking filter used in a video encoder/decoder based on a multilayer. In deciding a deblocking filter strength when performing a deblocking filtering with respect to a boundary between a current block coded by an intra-BL mode and its neighboring block, it is determined whether the current block or the neighboring block has coefficients. The filter strength is decided as a first filter strength if it is determined that the current block or the neighboring block has the coefficients, and the filter strength is decided as a second filter strength if it is determined that the current block or the neighboring block does not have the coefficients. The first filter strength is greater than the second filter strength.

    摘要: A method and apparatus for encoding and decoding a video signal by extending an application of directional intra-prediction. When performing a directional intra-prediction during video data encoding, a second block in a frame is searched in order to predict information of a first block included in the video data from the second block existing in the same frame as the first block, a residual between information included in the searched second block and the information included in the first block is calculated, and the calculated residual is encoded. The second block exists in a position adjacent to the first block, and the first block refers to the second block in a third direction existing between a first direction and a second direction that are adjacent to each other for use in the directional intra-prediction.
