    摘要: A method and an apparatus of decoding a video signal are provided. The present invention includes the steps of parsing first coding information indicating whether a residual data of an image block in the enhanced layer is predicted from a corresponding block in the base layer, from the bitstream of the enhanced layer, and decoding the video signal based on the first coding information. And, the step of parsing includes the step of performing modeling the first coding information based on second coding information indicating whether prediction information of the corresponding block in the base layer is used to decode the image block in the enhanced layer. Accordingly, the present invention raises efficiency of video signal processing by enabling a decoder to derive information on a prediction mode of a current block in a decoder instead of transferring the information to the decoder.

    摘要: In the method for decoding a video signal, at least a portion of a current image in a current layer is predicted based on at least a portion of a reference image, offset information and dimension information. The offset information may indicate a position offset between at least one boundary pixel of the reference image and at least one boundary pixel of the current image, and the dimension information may indicate at least one dimension of the current image.

    摘要: Disclosed is a method for providing and using information about inter-layer prediction when providing a video signal to a plurality of layers by encoding the video signal. The method for encoding an image signal to bit streams of an enhanced layer and a base layer, includes the steps of coding an image block in a picture of the enhanced layer into residual data based on image data of a block of the base layer corresponding to the vide block, and providing indication information through the bit stream of the enhanced layer, the indication information representing whether the coding is achieved in inter-layer prediction constraint or inter-layer prediction unconstraint.

    摘要: The present invention relates to a method for scalably encoding and decoding a video signal. In an embodiment of the present invention, motion information, such as reference indices, motion vector, modes, etc., for an enhanced layer can be derived from a base layer, and a reference index for an image block in the enhanced layer is determined using median criterion based upon the base layer. A reference index for a block, having the most pixels corresponding to those of the image block, in the base layer is selected as the reference index for the image block, and the nearer reference index is selected if more than one block in the base layer have the same pixels corresponding to those of the image block. And, a motion vector for the base layer block related to the selected reference index is selected as the motion vector for the image block.
