Abstract

The embodiment of the invention discloses a device for supporting multipath video signals. The device comprises a display, a microprocessor and a multipath multiplexing switch, wherein a control output port of the microprocessor is connected with a controlled port of the multipath multiplexing switch; video output interfaces of a plurality of operation devices are respectively connected with a digital video signal input end of the multipath multiplexing switch; and a digital video signal output end of the multipath multiplexing switch is connected with an input end of the display. The multipath multiplexing switch provided by the embodiment of the invention supports the video signal inputs of the video output interfaces of the plurality of operation devices and video line switching is realized under the control of the microprocessor, so as to provide video switching and playing for the plurality of operation devices; and the technical effects of reducing the quantity of displays and reducing the cost of facilities in a car are realized under an application scene needing multi-device video display.

Description

technical field [0001] The present invention relates to the technical field of vehicle communication, and more specifically, relates to a device and system supporting multi-channel video signal switching. Background technique [0002] Car video is to provide car users with monitoring video and human-computer interaction interface through the car screen under the control of the car processor. [0003] Taking the car screen as an example of an LCD screen, an existing LCD screen supports the video display of a single operating device. Generally, there are two ways, one is to control the digital video signal RGB565 or RGB888 transmission through a microcontroller; the other is The digital video signal RGB565 or RGB888 is controlled by the microcontroller through the original car bus signal and the decoder. In order to meet the needs of DVD video, navigation, TV, and video game consoles, multiple displays must be installed inside the car body. [0004] However, the above-mention...
