Method and apparatus for encoding/decoding video signal using prediction information of intra-mode macro blocks of base layer

The present invention, as using the inner (intra) prediction information of the mode block of the auxiliary layer, and encoding the image signal, to a method and apparatus for decoding the image data encoded accordingly, encodes the video signal into a scalable a MCTF scheme scale the enhanced but at the same time and outputs the bit stream of de-layer output bit stream of the base layer by encoding the video signal group in the indicated way, when encoded to the MCTF method, the internal mode, that is included in the bit stream of the base layer on the basis of the prediction information of the corresponding block coded in, for a given image block included in the frame of the video signal, and by using the coding before the value of the pixel adjacent to the image block coded in the error value, constraint information to transmits a bitstream off.
