Abstract:
1. An apparatus for discriminating a color format comprising: a plurality of signal processing paths for separating a luminance signal and a color signal from a broadcasting signal based on a plurality of color formats; a direct signal path for providing a direct output of the broadcasting signal without separating the luminance signal and the color signal therefrom; a relay device for selectively relaying the broadcasting signal as inputted to any one of the respective signal processing paths and the direct signal path; a detection device for detecting variation of the color format of the broadcasting signal based on an output signal from the signal processing paths; a discrimination device for discriminating the color format of the broadcasting signal based on the broadcasting signal as inputted through the direct signal path; and a control device for controlling the relay device so as to relay the broadcasting signal to the direct signal path, when variation of the color format is detected by means of the detection device.
