Cross-system file transmission method based on wireless screen projector

Abstract

The invention discloses a cross-system file transmission method based on a wireless screen projector. The cross-system file transmission method comprises the following steps that: a target client monitors the wireless screen projector connected with screen projection equipment through UDP broadcast; a socket channel is established; and the target client is remotely controlled through the socket channel, and a file is transmitted to the target client by the screen projection equipment, or the file is captured from the target client to the screen projection equipment. According to the invention, the target client monitors the wireless screen projector connected with the screen projection equipment through UDP broadcast, establishes the socket channel with the wireless screen projector, remotely controls the target client through the socket channel, and transmits the file to the target client or captures the file from the target client to the screen projection equipment, so rapid and stable transmission of the file between the projection screen equipment and the target client is achieved, the file transmission efficiency and speed are greatly improved, meanwhile, the type range of the transmitted file is widened, dependence on third-party software or external storage equipment is not needed, and the file transmission method and device can be suitable for richer use scenes.

Description

technical field [0001] The invention relates to the technical field of file transmission, in particular to a cross-system file transmission method based on a wireless screen projector. Background technique [0002] Wireless screen projection is also called wireless screen sharing, flying screen, and screen sharing. Specifically, it is to display the picture of mobile device A (such as mobile phone, tablet, notebook, computer) on the screen of another device B (tablet, notebook, computer, TV, all-in-one, Projector), the output includes various media information and real-time operation screen. Mature solutions that support wireless projection technology include Apple's Airplay screen mirroring, WIFI Alliance's Miracast protocol, DLNA push technology, APP software projection technology, and hardware projection technology. [0003] At present, all kinds of wireless screen projectors on the market only support the synchronization of small screen images and audio data, and the t...
