  • SCART INTERFACE CONTROL CIRCUIT AND VIDEO DEVICE USING THE SAME
    Publication number: 20110084735
    Abstract: A SCART interface control circuit outputs a mode switch signal to a switch signal pin of the SCART interface according to standby, widescreen and normal modes of video signals. The SCART interface control circuit comprises a first voltage circuit, a second voltage circuit, a voltage combination circuit and an amplifier circuit. The first and second voltage circuits output first and second voltage signals according to the video signal modes, respectively. The voltage combination circuit combines the first and second voltage signals into a combination voltage signal. The amplifier circuit amplifies the combination voltage signal so as to output the mode switch signal for indicating the video signal modes.
