Abstract

The embodiment of the invention discloses a projection screen data transmission method and device, electronic equipment and a storage medium, and the method comprises the steps: receiving feedback information sent by a target data receiving end according to received projection screen data, determining the data round-trip time of the screen projection data according to the information content of a preset data transmission field in the TCP header information in the feedback information; performing network bandwidth estimation according to the numerical change of the data round-trip time, and determining an adjustment strategy of a screen projection data coding parameter based on a network bandwidth estimation result and a current data sending bandwidth; adjusting the screen projection data coding parameter, coding the to-be-sent screen projection data according to the adjusted coding parameter, and transmitting the to-be-sent screen projection data. According to the technical scheme disclosed by the embodiment of the invention, the network state between two parties carrying out screen projection data interaction based on the TCP protocol is monitored, a screen projection data coding strategy is adjusted according to the network state, screen projection data transmission is carried out, and video lagging and pause caused by network problems in the screen projection process are reduced.

Description

Technical field [0001] Embodiments of the present disclosure relate to computer technology, and more particularly to a destinating data transmission method, device, electronic device, and storage medium. Background technique [0002] Typically, transmissions transmitted between the destinating data source and the video playback end are data transfer under the wireless local area. In the process of data transmission, it will encounter the latency of the network, jitter, packet loss, etc., which will cause video to play carton, or even the screen interrupt, to the user's experience is very poor. [0003] In the prior art, in order to be able to dynamically monitor the network state, the process of controlling the data transmission is usually employed in the UDP protocol (User DataGram Protocol, User Data). However, from the application developer's perspective, the application developer will give priority to the data transfer based on the TCP protocol (Transmission ControlProtocol, ...
