摘要
针对基于SPICE协议的云桌面全屏播放高清视频时存在占用带宽过大、容易卡顿、用户体验差等突出问题,提出使用压缩效率更高、更加先进的H.265视频压缩标准替换SPICE协议中原有MJPEG视频压缩算法的改进方案。实验表明,改进后的SPICE协议在播放视频时视频传输冗余量极大减少,占用网络带宽更少,视频播放流畅度更高,极大改善了用户体验。
In view of the outstanding problems of excessive bandwidth,easy freezing,and poor user experience when playing high-definition videos on the cloud desktop based on the SPICE protocol,a scheme is proposed which using the H.265 video compression standard with higher compression efficiency and more advanced to replace the original MJPEG video compression algorithm in spice protocol.Experiments show that the improved SPICE protocol greatly reduces video transmission redundancy when playing videos,occupies less network bandwidth,and has higher video playback smoothness,which greatly improves user experience.
