Abstract: A video transmission system is disclosed. The video transmission system comprises a multi-drop bus, a first source driving chip, a second source driving chip and a timing controller. The first source driving chip comprises a first source driving circuit and a first terminal circuit. The first terminal circuit is coupled to the multi-drop bus and the first source driving circuit for providing a first terminal resistor. The second source driving chip comprises a second source driving circuit and a second terminal circuit. The second terminal circuit is coupled to the multi-drop bus and the second source driving circuit for providing a second terminal resistor. The timing controller is coupled to the first source driving chip and the second source driving chip via the multi-drop bus.
