摘要： This invention relates to a method and apparatus for encoding video signals based on prediction information of an intra mode block of a sub-layer and decoding the encoded video data accordingly. The method encodes a video signal in a scalable MCTF scheme to output a bit stream of an enhanced layer, and simultaneously encodes the video signal using a pre-determined method to output a bit stream of a base layer. When the video signal is encoded in the MCTF scheme, an image block included in an arbitrary frame of the video signal is coded to be an error value using the uncoded value of pixels adjacent to the image block, on the basis of prediction information of the corresponding block coded as an intra mode, the corresponding block being included in a bit stream of the base layer and corresponding to the image block, and a bit stream including the coded image block is transmitted while constraint information being released.

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. Therefore, the method for decoding/encoding a video signal uses a variety of inter layer prediction methods according to the macroblock type of macroblocks of the current and base layers, and removes inter layer redundancy, resulting in increased coding efficiency.
