TELEVISION SIGNAL PROCESSING CIRCUIT

摘要

The television signal processing circuit has an input device for receiving a television signal and a signal processing circuit which includes a video memory having a delay time equal to a vertical scanning period of the television signal or to an integer multiple of the period. A luminance signal and a chrominance signal of the video signal are separated, or the scanning line is interplated. A second signal processing circuit without a video memory is arranged in parallel with first signal processing circuit and responsive to the television signal. A selector in response to a television signal to be processed which does not conform with the standard colour levision signal, selects the output of the second signal processig circuit.
