The invention relates to a vehicle-mounted application data transmission method. The method comprises the steps that an application request input to an integrated entertainment host by a user is acquired; the type of the application request is judged; when the application request is of a type of playing multiple paths of high-definition videos, wireless communication connection between the host and the vehicle-mounted TBOX is established, and the wireless communication connection is based on a network protocol not lower than WiFi 6; in response to the application request, the TBOX acquires anddownloads multiple paths of high-definition video data from the cloud server; the TBOX transmits the multiple paths of high-definition video data to a host through wireless communication connection;and the host correspondingly distributes the multiple paths of high-definition video data to the central control screen and the rear row screen so as to synchronously play the multiple paths of high-definition videos. According to the transmission method and system, the function of synchronous transmission of multiple paths of high-definition videos can be achieved, meanwhile, an original communication mode is prevented from being transformed, and the development cost is reduced.
Description
technical field [0001] The invention relates to the field of vehicle data transmission, in particular to a vehicle application data transmission method and system. Background technique [0002] At present, in-vehicle application communication is mainly based on 4G technology. The in-vehicle T-BOX (TelematicsBox) that supports 4G communication communicates with the cloud server to obtain service content data, and the service content data is sent to the integrated entertainment system through the in-vehicle 100M Ethernet architecture. Host for in-vehicle applications. [0003] With the continuous upgrading of in-car entertainment and audio-visual applications, the bandwidth of 4G communication is gradually unable to meet the needs of audio-visual applications, especially in the application scenario where multiple high-definition videos need to be played synchronously in real time in the car. The launch of high-bandwidth, low-latency 5G communications solves this pain point in...
