Problems solved by technology

[0004] Using the above-mentioned coding schemes is better for static, a large number of regular color blocks and window images with a lot of color block translation. However, the above-mentioned coding methods are used to transmit dynamic, colorful and irregularly changing dynamic images. When the compression ratio is low, it will take up a lot of bandwidth when using the virtual desktop to play video or play games. When the network condition is not good, network congestion and delay increase will occur, and the TCP retransmission mechanism will further aggravate the congestion, and finally the screen will appear. drop frame

Abstract

The invention discloses a screen image transmission method, apparatus and system. A specific embodiment of the method comprises the steps of receiving an image updating request; obtaining one or more rectangular dynamic regions unshielded by other windows in a dynamic window; combining the one or more rectangular dynamic regions into a rectangular region; removing the rectangular region from a screen region to obtain a static region; performing encoding on the rectangular region and the static region filled with a pure color by adopting a first encoder to obtain first encoded data; performing encoding on the static region and the rectangular region filled with the pure color by adopting a second encoder to obtain second encoded data, wherein a compression ratio of the first encoder is greater than that of the second encoder; and sending the first encoded data and the second encoded data to a user end. According to the screen image transmission method, apparatus and system, the jamming, delay and the like caused by excessively low compression ratio in dynamic image transmission is effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method, device and system for transmitting screen images. Background technique [0002] Virtual desktop technology is a remote control software, which is divided into server and client. After the server is started, it runs in the background. After the client successfully connects to the server through the TCP / IP protocol, it can display the desktop image of the machine where the server is located in real time in the window, and can provide the client with the function of remotely operating the server desktop. [0003] In related technologies, the virtual desktop technology uses a request update method during communication: on the one hand, the client will periodically request image updates from the server, and the server will encode the image displayed on the screen after receiving the update, and send it to the ...
