PURPOSE: To improve utilizing efficiency of a circuit and to simplify the circuit by continuously operating a motion-compensates sub-assembly, generating a half part of a compensated signal, temporarily storing the half part in an auxiliary memory stage in a field cycle and decoding the half part by adding it to a half part of a signal compensated next. CONSTITUTION: The motion-compensated sub-assembly 730 is provided with a decoder. The sub-assembly 730 temporarily stores the motion-compensated signal or compensates the signal, when an untransmitted field to which the motion is compensated is reproduced as well as receiving a motion information component, transmitted via a digital auxiliary TV channel 20. Specifically, the motion information component is received by the motion compensated sub-assembly 730 in a first motion step, and the half part of the motion is simultaneously compensated by using memory 733 supplying a first half-compensated field D2 (X-V) in a first operation step. The half-part of the motion is compensated by using the memory 733 supplying a second half compensated field D2 (X+V) from a vector V by the motion compensated sub-assembly 730 in a second operation step. |
