Problems solved by technology

However, the command-based encoding method in the prior art requires that the drawing command cannot be lost (otherwise the picture will be incomplete), so it is difficult to control the number of commands sent, and the traffic in the WAN environment is too large, so it is not suitable for remote desktops under the WAN. data transmission

Abstract

The invention discloses a data processing method for a virtual desktop, and the method comprises the steps of generating a current screen content on a canvas according to a drawing command when the drawing command is received; judging whether the available bandwidth of the current network is greater than a preset value or not; and if so, determining target area content in the current screen content, and performing compressed encoding operation on the target area content to obtain to-be-sent data so as to send the to-be-sent data to the client. According to the method, the real-time transmission of the remote desktop can be ensured on the premise of reducing the sending data volume corresponding to the drawing instruction. The invention furthermore discloses a virtual desktop data processing device, a computer readable storage medium and an electronic device, which have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a virtual desktop data processing method and device, a computer-readable storage medium and an electronic device. Background technique [0002] A key technology in virtual desktop is the need to transmit desktop content to the client through the network. In order to enhance user experience, how to make better use of limited bandwidth to transmit desktop content in a complex and changeable network environment is a key issue in virtual desktop technology. A problem that must be solved. Remote desktop encoding is a method to compress the screen content to reduce the amount of data sent. The screen content is generated by drawing commands, and different encoding methods depend on different drawing command processing procedures. [0003] In the prior art, the processing method of the remote desktop drawing command is mainly a command-based encoding method: each draw...
