Abstract

PURPOSE: To perform chrominance signal processing efficiently, by discriminating the system of a chrominance carrier signal with the output of killer detection and holding a changeover switch to a switching state matched to the system.
CONSTITUTION: A carrier signal of a color video signal of the standard MTSC, PAL and virtual NTSC system is processed for the chrominance signal by switching changeover switches 16, 17, 27 and 35. A changeover control circuit 41 controls the changeover switches 16, 17, 27 and 35 with a prescribed period, a carrier signal system is discriminated with a killer detecting output from a killer detection circuit 45, and the switches 16, 17, 27 and 35 are held to the switching state matched to the system. Thus, the chrominance signal processing can efficiently be made.
