Method and system for control transmission of virtual desktop image

Abstract

The invention discloses a transmission control method and system of virtual desktop images. The transmission control method comprises the steps that updating information of the desktop images are sent to a data processing center of a server end for demanding processing through a client end or a server end controller; image block division of the desktop images is carried out according to windows, image blocks are divided into a plurality of windows, window information is built, and the windows are further divided into dynamic areas and static areas according to a certain division rule; the data processing center of the server end obtains basic information of a current window and compares the basic information with image information of client end window image cache, and change image data of the current window compared with the client end window image cache are determined as image data to be sent; the image data to be sent are sent to the client end after being compressed by automatically-selected suitable compression algorithms; after the client end carries out uncompress on the received change image data, the change image data after uncompress are combined with the image information of the client end window image cache to generate and display new desktop images.

Description

technical field [0001] The invention relates to the technical field of virtual desktop image transmission, in particular to a method and system for controlling transmission of virtual desktop images. Background technique [0002] At present, computer remote control is widely used in the fields of network management and internal affairs communication of enterprises. It virtualizes the screen of the controlled terminal at the control terminal, and the user can control the controlled terminal in real time through the interface of the screen image, as if the user sits at the controlled terminal directly. Same as operating a computer. However, the remote control technology has a lot of defects in the acquisition of screen images, screen image compression, and remote image transmission. The screen image data transmission process occupies a large amount of bandwidth and even blocks the network, which affects real-time performance and security. [0003] With the increasing populari...

Problems solved by technology

However, while virtual desktops bring users a virtual interface environment like sitting next to the current host, they also bring many problems: the transmission of desktop images brings serious congestion problems to the network

For remote connections, the key to performance optimization lies in the size of bandwidth resources, but bandwidth resources are limited by physical conditions
