1. An video transmitter, for transmitting a video signal with a control signal, comprising:

  • an video capture module, for capturing a video signal;

    a synchronizing separator circuit, for receiving the video signal, and getting a synchronous signal of the video signal;

    a mixing circuit, coupled to a transmission interface, the mixing circuit receiving the video signal from the synchronizing separator circuit;

    a control unit, coupled to the synchronizing separator circuit and the mixing circuit, for counting the synchronous signal, and generating a counting number; and

    a signal receiver, coupled to the control unit, for receiving a control signal, and transmitting the control signal to the control unit;

    Wherein the counting number matches a pre-set number, the control unit transmits the control signal to the mixing circuit, the mixing circuit insert the control signal into the video signal, and transmits the video signal with the control signal to the transmission interface.
