ABSTRACT:
A television signal processing circuit which separates a television signal into a luminance signal and a chrominance signal or interpolates the scanning lines of the television signal by using a video memory such as a frame memory or a field memory. The circuit determines whether the television signal to be treated is a standard television signal or a non-standard television signal. Depending upon this determination, the signal processing circuit changes its operation mode so that it operates properly even in case the television signal is different from the standard television signal and contains jitter in the time axis like the signal from a VTR. When the television signal is a non-standard television signal, the processing circuit without the video memory operates.
