Video signal processing system.

摘要

A video signal processing system for outputting an EDTV signal from which an accompanying auxiliary signal is removed when the auxiliary signal of the inputted EDTV signal hh' is in the base-band frequency. The system includes an auxiliary signal period detection circuit (6-12) for outputting a detection signal "g" by detecting auxiliary signal periods dd11 and dd22 corresponding to the auxiliary signals dd1' and dd2' in the base band frequency and a mute circuit 4 for muting the EDTV signal in the auxiliary signal periods dd11 and dd22 in response to the auxiliary signal detection signal "g".
