An adaptive predictive encoding apparatus for encoding a video signal by utilizing correlation between frames in both the forward and reverse directions of the time axis. A prediction signal for use in deriving prediction error values to be encoded for a frame is selected by an adaptive prediction section (4), in units of blocks, from a plurality of mutually differently derived prediction signals, in accordance with the degree of correlation of the block with corresponding ones of a specific preceding independently encoded frame and a specific succeeding independently encoded frame. |
