Problems solved by technology

[0006] Although this solution can effectively solve the shortcomings of the pure software implementation solution, it also has some defects: adding a UWB accessory platform and an external power supply outside the host is very inconvenient to use
[0008] It can be seen that the graphics card and the network card in the prior art work separately. In the use of UWB technology, the graphics card part is usually wirelessized on the hardware to realize the wireless display function, or the network card part is wirelessized to realize the function of wirelessly transmitting data files, but no matter which This implementation fails to make full use of the bandwidth of UWB, and leads to considerable overlap of hardware, resulting in a serious waste of resources

Embodiment Construction

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] see figure 1 , figure 1 It is a working schematic diagram of a wireless data transmission device according to an embodiment of the present invention. The wireless data transmission device of the present invention is located inside a host 101, and through wireless transmission, it can transmit image data to a wireless display device 103 to realize a wireless display function; It is also possible to transmit non-image data to another host 102, or to receive non-image data from another host 102. Moreover, while realizing non-image data interaction between the host 101 and the host 102 , the host 101 can still send image data to the wireless display device 103 . The wireless device in the above-mentioned host 102 can be the wireless data transmission device of the present invention, or an existing wireless device. Here, for the ...
