Abstract:
1. A method for decoding a video signal performed by a video decoding system, comprising: deriving, with the video decoding system, a corresponding pixel value of a corresponding block in a base layer from the video signal, the corresponding block being referred by a current block in an enhanced layer, wherein the base layer represents an up-sampled base layer, and a spatial resolution of the up-sampled base layer corresponds to a spatial resolution of the enhanced layer; obtaining, with the video decoding system, a pixel prediction value of the current block from the corresponding pixel value; and reconstructing, with the video decoding system, the current block based on the pixel prediction value of the current block and a residual value, wherein a block type of the corresponding block is intra mode, and the residual value represents a difference value between the pixel prediction value of the current block and a pixel value of the current block.
