Problems solved by technology
The 5G frequency band has a higher frequency, carries more data, and has a shorter transmission distance
However, in some scenarios, the transmission of input event data between the terminal and the display device may be disturbed, affecting real-time and reliability
For example, the 5G WiFi channel is transmitting a large amount of audio and video data, and there are multiple 5G WiFi devices working at the same time near the scene, causing mutual interference
It can be seen that in the current application scenario of wireless screen projection technology, the real-time and reliability of transmitting input event data is not high, which affects the user experience after screen projection

Embodiment Construction
[0059] As described above, in the current wireless projection technology, a single 5G WiFi channel is used for data transmission. However, the input event data is sudden, and it is difficult to predict the moment of user operation. At the same time, this technical scenario is very sensitive to the delay of input event data. If the delay is too large, the same-screen effect will be affected. Therefore, once the 5G WiFi transmission channel used fails, it will seriously affect the user's experience of using the wireless projection technology.
[0060] Based on the above problems, embodiments of the present application provide a wireless communication method, related equipment, and system. In the embodiment of the present application, multiple independent wireless transmission channels are established between the display device and the terminal before data transmission, so as to prevent the occasional failure of a single channel from affecting the normal transmission of input eve...

The invention discloses a wireless communication method, related equipment and a system. A plurality of wireless transmission channels are established between the display device and the terminal, the display device supports input, and after the display device obtains input event data, the input event data can be transmitted to the terminal through the plurality of wireless transmission channels. The display device adds a serial number to the input event data according to a time sequence before transmitting the input event data. When the terminal receives the input event data through the plurality of wireless transmission channels, the type of the data can be determined based on the serial number of the transmitted input event data, and the input event data is processed based on the processing mode matched with the data type. Through redundant transmission of multiple channels and insertion of serial numbers in data, a terminal can conveniently distinguish data types and complete processing operation of a corresponding processing mode. The influence caused by data transmission delay after a single-channel fault can be avoided, and the real-time performance and reliability of transmission are ensured, so that the screen projection experience of a user is improved.
Description
