    摘要： In one embodiment, the method for decoding a video signal using inter layer prediction includes obtaining a residual signal of a corresponding block in a base layer from a base layer bitstream, scaling the residual signal of the corresponding block in the base layer, obtaining a residual signal of a current block in an enhanced layer from an enhanced layer bitstream, obtaining a prediction pixel value of the current block in the enhanced layer based on an intra prediction mode of the corresponding block in the base layer and a pixel value of a neighboring block in the enhanced layer, and reconstructing the current block by using the prediction pixel value of the current block, the residual signal of the current block.

    摘要： A method for decoding/encoding a video signal using an inter-layer prediction process is disclosed. The method for decoding a video signal including several layer information includes: a) acquiring a first prediction signal for a current block of an enhancement layer and a residual signal based on at least a base layer block; b) smoothing the sum of the first prediction signal and the residual signal, and generating a second prediction signal for the current block; and c) reconstructing the current block based on the second prediction signal, wherein the step a) for generating the first prediction signal is based on prediction mode information of at least the current block. Therefore, the method for decoding/encoding a video signal uses a variety of inter layer prediction methods according to the macroblock types of macroblocks of the current and base layers, and removes inter layer redundancy, resulting in increased coding efficiency.
