  • Video device, output switching method for video device, and cable discriminating method
    Patent number: 8154661
    Abstract: A video device comprises: a video signal processor generating a standard definition video signal at least having a composite signal and a high definition component video signal; an outputting unit outputting the standard definition video signal or the high definition component video signal to a cable to be connected; a discriminating unit discriminating a kind of cable connected to the outputting unit; and a switch allowing the outputting unit to selectively output the standard definition video signal and the high definition component video signal on the basis of the discrimination result of the discriminating unit. When the discriminating unit determines that the cable connected to the outputting unit is a cable for a high definition signal, the switch allows the outputting unit to output the high definition component video signal.
