Description

Virtual desktop configuration, acquisition method and device

Technical field

The present invention relates to the field of communications, and in particular, to a configuration, an acquisition method, and an apparatus for a virtual desktop.

Background technique

With the rapid development of cloud computing technology, the application of virtual desktops has become more widespread. The concept of virtual desktops is not to configure each user with a desktop personal computer (PC) running an operating system, but to virtualize the user's desktop by running an operating system on a server in the data center. Users can connect to virtual desktops through virtual desktop clients from client devices (thin terminals), and users access their virtual desktops as if they were accessing existing locally installed desktops. In the actual operation process, the local input of the terminal, for example, a common mouse and keyboard operation is sent to the virtual desktop in the server through the network, and then the virtual desktop responds, and the updated desktop is sent to the terminal for display through the network. .

In the process of using virtual desktops, most of the data exchanged between the terminal and the server is picture data related to desktop updates. In order to save network bandwidth, the updated image is usually compressed. The compression method used can theoretically select various popular compression methods, which may include: lossless compression and lossy compression.

Video playback capability is an important indicator of the performance of virtual desktops. At present, there are two general technical solutions: one is to play video in the virtual desktop of the server, and the video playing window is regarded as an ordinary virtual desktop update. The server captures the updated image according to the preset frequency, and performs the update image. After the compression process, it is sent to the terminal, and finally the terminal receives the compressed data and decompresses the compressed data and displays it. The other is that the virtual desktop in the server does not play the video, but sends the video data directly to the terminal. The terminal plays the video locally and displays it at the specified location according to the requirements of the server. The latter is generally referred to as video redirection. Due to the existence of multiple video compression algorithms, it is required to have a universal video decompression capability if the video redirection function is desired.

In summary, the use of virtual desktops requires the terminal to have multiple images and video decompression capabilities. An important purpose of using virtual desktops is to reduce the cost of compression, so the terminals in the virtual desktop usage environment are mostly embedded devices. Due to the processing power and hardware architecture limitations of embedded devices, it is difficult to fully support various popular image decompression methods, and it is also impossible to have the universal video decompression capability of a general-purpose architecture PC.
