Abstract

PURPOSE:To enable to receive two TV signals having two horizontal scanning frequencies, by converting a horizontal scanning frequency of the standard system into n-times of said frequency and providing a horizontal deflection circuit which operates with n-times scanning frequency of that of the standard system. CONSTITUTION:A demodulating signal of a video signal of the standard system outputted from a demodulation circuit 2 enters a signal conversion circuit 3 to be a signal converted into n-times speed and applied to an amplifying circuit 4. A synchronizing separation circuit 5 separates the synchronizing signal obtained from the circuit 2 into horizontal and vertical synchronizing signal. The horizontal synchronizing signal is applied to a multipication circuit 7, which converts the signal into a signal having n-time frequencies and supplies to a horizontal deflection circuit 8. On the other hand, the video signal in n-times horizontal scanning frequency of the standard system is given to input terminal and demodulated at a demodulation circuit 10. The demodulation signal of the circuit 2 is applied to the circuit 4. A synchronizing separation circuit 12 separates the synchronizing signal into the vertical and horizontal synchronizing signals and applies them to a vertical deflection circuit 6 and a horizontal deflection circuit 8 respectively.
