A video transmission apparatus and the connector module thereof are provided. The connector module includes a first resistor and a second resistor. The first resistor is coupled between a voltage source and a transmission pin. The second resistor is coupled between a ground terminal and a connector. When the transmission pin is in a floating state, the transmission pin outputs a floating voltage. And when the connector is coupled to the transmission pin, the transmission pin outputs a connection voltage. According to the DC voltage output by the transmission pin, the connector module judges the coupling state between the connector and the transmission pin. |
