METHOD AND DEVICE FOR BOUNDARY PROCESSING USING NEIGHBOUR BLOCK INFORMATION IN SCALABLE VIDEO ENCODER/DECODER
摘要
A method and a device for processing a boundary with peripheral block information in a scalable imaging encoder/decoder are provided to offer previously restored information of an upper layer as boundary information, which is needed for enlarging a block corresponding to a lower layer through down-sampling, when a small lower layer is encoded and decoded. A macroblock mode determiner(120) determines a macroblock mode of a lower layer when a scalable image is encoded/decoded. A boundary pixel information generator(130) generates boundary pixel information by performing down-sampling according to an up-sampling ratio with protected information of a block close to the macroblock of an upper layer when the macroblock mode of the lower layer is an internal mode. An up-sampler(140) performs up-sampling of the lower layer based on the boundary pixel information.
