Abstract:
An encoding and decoding method and apparatus are disclosed. whereby, According to the disclosed method, in response to a current frame including a current block being a P frame, a motion vector and an intra-mode-to-inter mode ratio of a frame encoded and decoded previously to the current frame are analyzed in order to determine a temporal search range and a spatial search range of a reference frame.
