Abstract
PURPOSE: To exercise write control over a memory without changing the order of storage by generating a control signal for the command of the write control over the memory by using a correcting signal when no data synchronizing signal arrives by detecting a horizontal synchronizing signal and then by generating the correcting signal a certain time after the horizontal synchronizing signal.
CONSTITUTION: Correcting signal generating circuit 8 is provided and correcting signal C is generated a certain time after a horizontal synchronizing signal obtained by horizontal synchronizing signal separating circuit 7. This correcting signal C is inputted to the write timing control circui. If any data synchronizing signal is not detected owing to a dropout, etc., write timing control circuit 4 and write counter 5 are operated normally by using correcting signal C as a substitute for control signal B.
