Abstract
PURPOSE: To improve a receiving picture quality by taking the interrelation between line information and one-line preceding information when an error is detected in a certain line and adopting only picture element information having interrelation.
CONSTITUTION: One-line signals from terminal 1 are stored in shift register 3 by clocks from terminal 2. When a program code and a line code are read into register 3, the output of register 3 is compared with the output of pattern generation circuit 4 by comparator circuit 5 to detect a code error. Data of register 3 is applied to shift register 6 furthermore and is delayed by one horizontal period. This delayed signal and the signal which is not delayed are applied to comparator circuit 7. According to the output of circuit 5, circuit 7 controls switching circuit 8 to output signals from register 3 as they are when no error is detected and the picture element interrelation to one-horizontal period preceding information can be taken in case of error, and circuit 7 outputs signals as picture signal absence when the interrelation above cannot be taken.
