Example Embodiment

[0018] In order to make the purpose, technical solutions and effects of this application clearer and clearer, the following further describes this application in detail with reference to the drawings and embodiments.

[0019] The present application provides a screen projection method, which aims to solve the problem of low data transmission efficiency in the existing screen projection solution and prone to stagnation in streaming. See figure 1 with figure 2 , figure 1 It is a schematic diagram of the structure of the first embodiment of the projection system of this application, figure 2 It is a schematic flowchart of the first embodiment of the projection method of this application. In this embodiment, the projection system 100 includes a projection device 10 and a target screen device 20. During the projection process, the projection device 10 transmits the projection data obtained by itself to the target screen device 20 and displays it on the target screen. . The specific...

Abstract

The invention discloses a screen projection method, a screen projection system and a storage device, and the method comprises the steps: obtaining screen projection data, the screen projection data comprising a first type of screen projection data and/or a second type of screen projection data; transmitting the screen projection data to target screen equipment, therefore, the target screen devicereceives and displays the screen projection data, wherein the application layer is provided with at least a first transmission channel and a second transmission channel, the first type of screen projection data and the second type of screen projection data of the application layer are transmitted through the first transmission channel and the second transmission channel respectively, and the low-delay user datagram transmission protocol is used for transmitting the screen projection data on the transmission layer. In this way, the screen projection method and device can reduce the lagging in the screen projection process and improve the fluency.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a screen projection method, system and storage device. Background technique [0002] With the development of electronic technology, it is more and more common to put the data on one device to another device for display, such as sending the video played on a mobile phone or tablet to a smart TV for display and playback. Currently common screen projection solutions generally use a Real Time Messaging Protocol (RTMP) protocol based on a Transmission Control Protocol (Transport Control Protocol, TCP) channel to send data. However, the transmission efficiency of this transmission method is relatively low, especially in the case of poor network conditions, it is prone to network congestion, which in turn leads to stuck streaming. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a screen projection method, system ...
