Patent ID: 8923399

Claim:
A method of processing a video signal with a decoding apparatus, comprising: obtaining, with the decoding apparatus, a global disparity vector of a current slice in a current view, the global disparity vector of the current slice being derived from a global disparity vector of an anchor picture, the anchor picture being a coded picture in which all slices reference only slices corresponding to a same time and a different view of the anchor picture; extracting, with the decoding apparatus, a motion skip flag from the video signal, the motion skip flag indicating whether motion information of a current block in the current view is derived from a reference block in a neighboring view, the reference block included in an inter-view reference picture of a reference picture list; extracting, with the decoding apparatus, offset refinement information of the current block based on the motion skip flag, the offset refinement information being an offset vector between a corresponding block indicated by the global disparity vector of the current slice and the reference block, the corresponding block being in the neighboring view, the corresponding block included in the inter-view reference picture of the reference picture list; obtaining, with the decoding apparatus, a refined global disparity vector of the current block using the global disparity vector of the current block and the offset refinement information; determining, with the decoding apparatus, the reference block for the current block using the refined global disparity vector; deriving, with the decoding apparatus, the motion information of the current block from the determined reference block; and decoding, with the decoding apparatus, the current block using the motion information of the current block.
