Abstract
In order to achieve centralized management, efficient use and privacy control of computer resources, a cloud-desktop system based on video stream is designed and implemented. A general-purpose server with VirtualBox virtualization technology is applied to achieve desktop virtualization. A freescale i.MX6DL ARM processor for hardware decoding is the core of client terminal. The improved state-of-the-art H.264 video compression standard is applied in desktop image compression. A smooth network traffic transfer method is used in desktop video stream transmission. The Linux kernel module is used to redirect mouse and keyboard messages. Experimental results show that when the virtual desktop resolution is 1 280×720, this cloud-desktop has a more stable display quality and less network traffic around 500 KB/s compared with commonly used desktop transfer protocols, in addition the very short response time around 120 ms.关键词
