Problems solved by technology

[0003] In related technologies, in order to meet the above-mentioned requirements, in-vehicle infotainment systems generally adopt a linear transmission structure, which requires the output unit to have multiple physical video output channels, and a dedicated video codec unit and transmission cable must be added for each output. Increase the number of wiring harnesses for the on-board infotainment system, increase the cost and structure complexity of the on-board infotainment system, and the transmission delay is high

Abstract

The invention provides a vehicle-mounted infotainment system, a vehicle and a communication method of the vehicle-mounted infotainment system. The system comprises at least one display unit; a host, wherein the host and the display unit are sequentially connected through a daisy chain topological structure, and the host is used for transmitting at least one path of video data to the display unit connected with the host through the daisy chain topological structure; and the display unit is used for acquiring the video data belonging to the unit according to the transmission routing protocol after receiving the video data, displaying the video according to the video data belonging to the unit, and transmitting the video data to the next display unit. Therefore, the system adopts a daisy chain topological structure; only one transmission cable and one video physical channel are needed to realize respective display of multiple paths of different videos on different display units, so the display requirements of different display units are met, the transmission delay of the system is reduced, the number of wiring harnesses of the system is reduced, the system cost is reduced, and the system structure is simplified.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a vehicle infotainment system, a vehicle and a communication method of the vehicle infotainment system. Background technique [0002] With the development of intelligent network technology of the Internet of Vehicles, the number of display units in the car and the trend of increasing the size of the display screen are becoming more and more obvious, and the demand for video interaction (transmission) between multiple systems in the car is also increasing. For example, the video data of the in-vehicle infotainment system needs to be synchronously transmitted to the in-vehicle display units such as digital instrumentation, HUD (Head Up Display), rear seat entertainment display system (RSE), and some of the in-vehicle infotainment system units The video content is transmitted to the corresponding display unit in the car according to different display requirements. ...
