1. A method for encoding of video picture, comprising:
generating a bitstream for video signals, the bitstream comprises a plurality of syntax elements, wherein the plurality of syntax elements comprise a first identifier, wherein a third identifier and a second identifier are conditionally signaled based on a value of the first identifier, wherein a fourth identifier is conditionally signaled based on a value of the second identifier and the third identifier, wherein the first identifier indicates that an affine motion model based motion compensation is enabled for a video sequence including a picture block to be processed, wherein the second identifier indicates that an affine motion model-based advanced motion vector prediction (AMVP) mode is used for inter prediction of the picture block and the third identifier has a true value, wherein a false value of the third identifier indicates that a 6-parameter affine motion model based motion compensation is disabled for the video sequence and the true value of the third identifier indicates that the 6-parameter affine motion model based motion compensation is enabled for the video sequence, wherein a true value of the fourth identifier indicates that the 6-parameter affine motion model-based motion compensation is used for inter prediction of the picture block, and wherein the false value of the fourth identifier indicates that a 4-parameter affine motion model-based motion compensation is used for inter prediction of the picture block; and
sending the bitstream to a decoding apparatus.
