The present invention relates to a method and apparatus for sequentially executing inter-frame and intra-frame joint prediction encoding and a method and apparatus for sequentially executing inter-frame and intra-frame joint prediction decoding. The method for sequentially executing inter-frame and intra-frame joint prediction encoding comprises: performing first prediction on an encoding unit or a block unit, and obtaining at least one group of candidate prediction parameters that comprise motion vector information, or at least one group of candidate prediction modes and corresponding distortion degree information; performing second prediction on the basis of a residual value formed after the first prediction, selecting one candidate prediction parameter as a reference prediction parameter, determining a motion vector difference according to the motion vector information and a motion vector of a current prediction unit, and determining a predicted difference according to the motion vector difference and dist
