RECEIVING SYSTEM FOR BAND-COMPRESSION IMAGE SIGNAL

When the receiving system for a band-compression image signal receives a dropout signal representing a dropout portion of an image signal, an output of the third delay circuit of the temporal filter for motion detection processing, that is, motion information of an image signal, which precedes by one field, and a dropout signal activate the signal selection control circuit to produce an output signal for controlling the operation of the signal selection circuit, so that an output signal of the first delay circuit is selected for a static portion of an image, and an output signal of the dropout compensation circuit is selected for a moving portion of an image, so as to effect compensation control of the dropout portion of an image signal, thereby preventing deterioration of the quality of an image.
