Abstract

The invention discloses a client, a universal serial bus (USB) device and a display processing system and method, relating to the field of communication. By the client, the USB device and the display processing system and method, the problems of more resources of a central processing unit (CPU) of the client are occupied and the decoding speed is relatively slow during decoding of the client can be solved. The display processing system comprises the client and the USB device, wherein the client is used for being communication with a server to acquire display data, existing in a coding form, in the server, send the display data, existing in the coding form, in the server, to the USB device, and decode in the USB device; and the USB device is used for receiving the display data sent from the client, processing the display data and transferring the processed display data to a displayer of the client so as to display a desktop on the displayer. The display processing system is mainly used for a remote desktop technology.

Description

technical field [0001] The present invention relates to the communication field, in particular to a client, a USB (Universal Serial Bus, Universal Serial Bus) device, and a display processing system and method. Background technique [0002] A remote desktop is one that displays another computer's display on the current display. It is also called virtual desktop, which is a popular office mode in the current enterprise office environment. Remote desktop involves remote screen display technology, which is closely related to user experience. [0003] At present, in the case of remote desktop combined with existing screen display technology, the specific process of its remote desktop display is that the desktop protocol server captures the picture from its display driver, and through the VDI (Virtual Desktop Infrastructure, virtual desktop infrastructure) desktop protocol will The captured screen images are compressed and sent to the client, and the client decompresses the dat...
