| Zusammenfassung: | An apparatus for discriminating a color format comprises signal processing paths, a direct signal path, a relay device, a detection device, a discrimination device and a control device. The signal processing paths separate a luminance signal and a color signal form 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 inputted to any one of the respective signal processing paths and the direct signal path. The detection device detects variation of the color format 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 inputted through the direct signal path. The control device controls 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. |
