Abstract
An apparatus discriminates a color format. The signal processing paths separate a luminance signal and a color signal from a broadcasting signal based on a plurality of color formats. The direct signal path provides a direct output of the broadcasting signal without separating the luminance signal and the color signal therefrom. The relay device selectively relays the broadcasting signal as input to any one of the respective signal processing paths and the direct signal path. The detection device detects color format variation of the broadcasting signal based on an output signal from the signal processing paths. The discrimination device discriminates the color format of the broadcasting signal based on the broadcasting signal as input through the direct signal path. The control device controls the relay device to relay the broadcasting signal to the direct signal path when color format variation is detected by the detection device.
