ABSTRACT:
A video signal processing apparatus for processing a video signal having: a memory circuit for receiving a video signal and storing received video signal; a synchronization signal separation circuit for separating a synchronization signal included by the received video signal, and transmitting the synchronization signal; a first counter for transmitting count data by performing a counting operation in synchonization with the synchronization signal transmitted from the synchronization signal separation circuit or by spontaneously performing the counting operation; a second counter for transmitting count data by spontaneously performing the counting operation; a memory control circuit for controlling writing or reading of the video signal to and from the memory circuit in accordance with the count data transmitted from the first counter; a first decoder for resetting the second counter in accordance with a value denoted by the count data transmitted from the first counter; and a second decoder for resetting the first counter in accordance with a value denoted by the count data transmitted from the second counter, so that a video signal can be formed while preventing disorder of the synchronization signal.
