Abstract

PURPOSE: To ensure the decoding of the TV signals featuring the reduced impairment of the reproduced picture and no disturbance of the raster scan be replacing the registered signal of the erroneous block with the analogous signal of the error- free block.
CONSTITUTION: Decoding circuit 3 decodes the received signals for each block, and the error is checked via detector circuit 5 for the decoding signals with every block. And the position of the block is memorized in memory circuit 2 until the error is corrected by the refresh signal for the erroneous block, and the registered signals of the erroneous block are replaced with the analogous signals of the error- free block at multiplexer 7. Thus, the decoding of the TV signals becomes possible with reduced impairment of the reproduced picture and with no disturbance of the raster scan.
