Abstract
This application provides video picture prediction methods and apparatuses. In an implementation, a method for encoding of video picture comprises generating a bitstream for video signals, the bitstream comprises a plurality of syntax elements, wherein the plurality of syntax elements comprises a first identifier indicating that an affine motion model based motion compensation is enabled for a video sequence including a picture block to be processed, wherein a second identifier is conditionally signaled at least based on a value of the first identifier, wherein a false value of the second identifier indicates that a 6-parameter affine motion model based motion compensation is disabled for the video sequence, and wherein a true value of the second identifier indicates that the 6-parameter affine motion model based motion compensation is enabled for the video sequence.
