Abstract:
1. A method for decoding a video signal, comprising: obtaining, with a video coding apparatus, position information of a current block in a current image in an enhanced layer; obtaining, with the video coding apparatus, offset information between at least one boundary pixel of a reference image and at least one boundary pixel of the current image from one of a sequence parameter set and a slice header, the reference image being up-sampled from an image in a base layer, the image in the base layer being a residual-coded image, the offset information including, obtaining, with the video coding apparatus, position information of a reference block in the reference image based on the position information of the current block and the offset information; obtaining, with the video coding apparatus, reference residual data based on the offset information and the position information of the reference block; obtaining, with the video coding apparatus, residual data of the current block based on the reference residual data; and decoding, with the video coding apparatus, the current block based on the residual data of the current block.
