In-car multimedia video device and image channel switching circuit

Abstract

The present invention discloses an in-car multimedia video device and image channel switching circuit. The in-car multimedia video device includes a display device and a multimedia image circuit that is electrically coupled to the display device. The multimedia image circuit includes a first image circuit, a second image circuit, an image channel switching circuit that is electrically coupled to the first image circuit and the second image circuit, and an input circuit that is electrically coupled to the image channel switching circuit. The image channel switching circuit includes a switching circuit, a first serializer circuit, a second serializer circuit, a deserializer circuit, and a control circuit. The switching circuit is configured to control the first serializer circuit to be electrically coupled to the deserializer circuit or the second serializer circuit to be electrically coupled to the deserializer circuit according to a switching signal, so that the display device is configured to display an image according to a first image signal or a second image signal.
