[0043] See Figure 1A , The flowchart of the first embodiment of the video decoding method of this application:
[0044] Step 101: Obtain an initial candidate motion vector set of the currently decoded block.
[0045] Specifically, the spatial candidate motion vector can be obtained according to the surrounding decoded blocks of the current decoded block, and the temporal candidate motion vector of the current decoded block can be obtained according to the reference frame. The reference frame is the previous frame of the current frame where the current decoded block is located, or the next Frame, or the previous frame and the next frame, the spatial domain candidate motion vector and the time domain candidate motion vector form an initial candidate motion vector set.
[0046] See Figure 1B , Is a schematic diagram of the motion vector selection of the decoded block in the B frame with bidirectional motion compensation. Assuming that the decoded block mv in the current frame is the c...
