Abstract
In an adaptive prediction encoding device which carries out adaptive encoding of a digital picture signal by making a selector adaptively select a two-previous predictor, a previous field predictor, and a higher order intraline predictor in accordance with the digital picture signal, a first selection forcing circuit forces a selector to select the higher order intraline predictor at first timing of fixed scanning lines which periodically appear at a period of (2N+1) scanning lines in each field of successive frames of the digital picture signal, where N represents a natural number. A second selection forcing circuit forces the selector to select the higher order intraline predictor at second timing of additional scanning lines which precede the fixed scanning lines by (m-1) scanning lines in each field of an m-th frame of the digital picture signal, where m consecutively varies from 2 to (2N+1) which is equal to M.
