ABSTRACT:
This invention relates to a method and apparatus for encoding video signals using 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 schemes, an image block included in an arbitrary frame of the video signal is coded as an intra mode using pixels adjacent to the image block, on the basis of prediction information of the corresponding block coded as the intra mode, the corresponding block being included in a bit stream of the base layer and corresponding to the image block.
