摘要： An apparatus for band compression processing of a picture signal which generates forecasting error signal (block 3) and movement vector (block 1) and updates only the movement vector during a comb-out operation. During comb-out processing, a picture signal is recirculated (block 5) while the movement vector is produced and accumulated (block 11). At the end of the comb-out processing, the change in the movement vector from the accumulated vector is within a desired range. Therefore, a scale of circuit does not increase for detecting the movement vector after the comb-out operation.

摘要： A differential coding circuit including a subtractor (7,8). a quantizer (3) for quantizing a differential signal (D) from the subtractor (1), and a predicted signal generating circuit (4,5,6) for generating a predicted signal on the basis of a quantized differential signal from the quantizer (3). The subtractor (7,8) subtracts the quantized differential signal of the quantizer (3) and the predicted signal from the sampled input signal (A). The critical path of the circuit is shortened, therefore the operation speed of the differential coding circuit increases.
