The invention relates to a vehicle application data transmission method, comprising: obtaining an application request input by a user to an integrated entertainment host; judging the type of the application request; and establishing the host and the vehicle T-BOX when the application request is a type of multi-channel high-definition video playback wireless communication connection, wherein the wireless communication connection is based on a network protocol not lower than Wi‑Fi6; in response to application requests, T‑BOX obtains and downloads multiple channels of high-definition video data from the cloud server; T‑BOX transmits multiple channels of high-definition video data through wireless The communication connection is transmitted to the host; the host distributes the multi-channel high-definition video data to the central control screen and the rear screen correspondingly for synchronous playback of multi-channel high-definition video. The transmission method and system adopted in the present invention can satisfy the function of synchronous transmission of multi-channel high-definition video, avoid the modification of the original communication mode at the same time, and reduce the development cost.
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 sends the service content data to the integrated entertainment system through the in-vehicle 100M Ethernet architecture. host for in-vehicle applications. [0003] With the continuous upgrading of in-vehicle entertainment audio and video applications, the bandwidth of 4G communication gradually cannot meet the needs of audio and video applications, especially in the application scenarios that require real-time synchronous playback of multi-channel high-definition video in the car. The launch of high-bandwidth, low-latency 5G communication solves this pain point in o...
