METHOD AND APPARATUS FOR ENCODING/DECODING VIDEO SIGNAL USING BLOCK PREDICTION INFORMATION

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.
