Patent ID: 7209184

Claim:
Video apparatus comprising an input switching matrix, to which at least one video input is coupled, the video input comprising a terminal for a component video signal and a CVBS terminal (Video) or a S-VHS terminal, a synchronization signal detector coupled to a luminance output of the input switching matrix, a color decoder coupled to the luminance output and to a chrominance output of the input switching matrix, an output switching matrix coupled to the input switching matrix and to the color decoder, and a microcontroller coupled to the input switching matrix and to the synchronization signal detector for controlling the input switching matrix, wherein the detection of the component video signal is made automatic by means of the microcontroller, which, after selecting a Y video input, sets the input switching matrix to pass a signal from the terminal for the component video signal of said video input to the synchronization signal detector, and, in case this terminal provides a valid luminance signal, then a component video signal is recognized, which is switched through then by the output switching matrix, and, in case no valid luminance signal is available at the component video terminal, then the microcontroller switches the input switching matrix to the CVBS terminal or a S-VHS terminal of said video input, respectively, for checking for a valid synchronization signal by means of the synchronization signal detector.
