Abstract: Methods of encoding and decoding for video data are describe in which significance maps are encoded and decoded using non-spatially-uniform partitioning of the map into parts, wherein the bit positions within each part are associated with a given context. Example partition sets and processes for selecting from amongst predetermined partition sets and communicating the selection to the decoder are described.

Abstract: A video decoding method includes acquiring N pieces of motion information of a target area according to motion-related information in a bitstream, where N is an integer greater than or equal to 2, separately performing a motion compensation operation on the target area by using each piece of motion information in the N pieces of motion information to obtain N predictions of the target area, where each prediction in the N predictions of the target area includes predicted values of all sampling points in the target area, acquiring a prediction selection reference of the target area, where the prediction selection reference of the target area is values of all sampling points in a corresponding reference area of the target area, and determining a final prediction of the target area according to the N predictions of the target area and the prediction selection reference of the target area.
