ABSTRACT:
A multi-television broadcasting signal receiving apparatus and method thereof are provided. In the apparatus, if aerially transmitted several television broadcasting signals are tuned and the tuned signal is inputted as an IF signal, a microcomputer outputs a different chrominance control signal according to the broadcasting system by using the input IF signal. A chrominance signal amplifying portion varies a color concentration of a detected signal according to the broadcasting system by the chrominance control signal output from the microcomputer so as to discriminate the broadcasting system. The color concentration is automatically corrected without the need of an extra correction circuit by correcting the color concentration of the broadcasting signal discriminated by a preprogrammed different gain according to the broadcasting system of the received signal. This effect can be applied to a television for receiving a plurality of broadcasting signals.
