Abstract:
A signal transmitting circuit includes a HDMI signal transmitting unit adapted to output a HDMI signal, a VGA signal transmitting unit adapted to output a VGA signal, a VGA signal processing unit, and a transmitting control unit. The VGA signal processing unit is connected to the VGA signal transmitting unit. The VGA signal processing unit is adapted to receive the VGA signal from the VGA signal transmitting unit, and include a detection signal into the VGA signal to form a combination signal. A transmitting control unit is connected to the VGA signal processing unit and the HDMI signal transmitting unit. The transmitting control unit is adapted to receive the combination signal and the VGA signal, to distinguish the combination signal and the VGA signal, and to output the combination signal and the VGA signal to the appropriate receivers.
