Abstract
A predictive coding/decoding system for block-formed picture signals includes predictive coding and decoding units in transmitter and receiver sides, respectively: each of the predictive coding and decoding units is provided with a control pulse generator responsive to a horizontal synchronization pulse in the picture signal to produce a sampling signal and a select signal, and a pair of selectors together responsive to the select signal to select a sum of a prediction signal and a prediction error signal or a fixed value as an input of a prediction circuit, the pair of selectors selecting the fixed value for a partial picture block including a fraction of pixels due to the block formation.
