Abstract

The invention discloses a method for virtual desktop compression, which comprises the steps that at a step S101, an instruction buffer device is constructed in a virtual display card of a virtual desktop system, and a rendering instruction is saved; at a step S102, desktop images and the rendering instructions are acquired regularly from the virtual display card; at a step S103, the images are compressed by an image compressor; at a step S104, the compressed images are sent to a client side by a network; at a step S105, the compressed images are received by the client side; at a step S106, the compressed images are decoded by the client side; and at a step S107, decoded images are displayed by the client side. The method for the virtual desktop compression disclosed by the invention makes use of a rendering instruction buffer area which is synchronous with the desktop image and established on a virtual desktop server side and applies the instructions to assist the image compression in order to reduce complexity of the image compression and increase quality of the image compression. Meanwhile, standards and specifications adopted by the image compression do not influence performance and cost of the client side, so that multi-media application capability of the virtual desktop is strengthened.

Description

technical field [0001] The invention relates to the technical field of virtual desktops, in particular to a method for compressing virtual desktops. Background technique [0002] In recent years, the research and application of virtualization technology has gradually deepened with the development of cloud computing, including hardware platform virtualization, network virtualization and desktop virtualization. It has been widely accepted by users to use mobile phones or other portable devices to use the cloud platform for office or business processing through the network. Desktop cloud (Virtual Desktop Cloud, VDC) means that users can access remote desktop applications across platforms through a thin client or any other device connected to the network just like using a local personal computer (PC). The desktop operating system and application environment of the desktop cloud are centrally deployed in a remote data center, and the local terminal is just a low-performance clie...
