Abstract: The present disclosure discloses a method for determining a motion vector, comprising the steps of: determining at least one inter-layer reference block by referring to an inter-layer corresponding block of a current processing block; determining the motion vector(s) of the current processing block according to the motion vector(s) of the determined at least one inter-layer reference block as well as the motion vectors of the other adjacent blocks of the current processing block. In comparison with the prior art, in the present disclosure, when a motion vector of a current processing block is derived, the information of the inter-layer corresponding block is referred to and inter-layer correlation in a multi-layer video is utilized, thus compression and coding efficiency for a video are improved remarkably.

Abstract: The present application discloses an encoding method for global disparity vector. The method includes determining global disparity vector prediction information and a global disparity vector of a current encoding region, and encoding information about the global disparity vector of the current encoding region and writing the information into a bit-stream as required, wherein the information about the global disparity vector of the current encoding region is used to determine the global disparity vector of the current encoding region by a decoder.
