Nowadays video streaming is growing over the social clouds, where end-users always want to share High Definition (HD) videos among friends. Mostly videos were recorded via smartphones and other HD devices and short time videos have a big file size. The big file size of videos required high bandwidth to upload and download on the Internet and also required more time to load in a web page for play. So avoiding this problem social cloud compress videos during the upload for smooth play and fast loading in a web page. Compression decreases the video quality which also decreases the quality of experience of end users. In this paper we measure the QoS of different standard video file formats on social clouds; they varied from each other in resolution, audio/video bitrate, and storage size.

服务质量 (QoS):视频流的测量

如今,视频流在社交云上不断发展,最终用户总是希望在朋友之间共享高清 (HD) 视频。大多数视频是通过智能手机和其他高清设备录制的,短时间视频的文件很大。视频的大文件大小需要高带宽在互联网上上传和下载,也需要更多的时间加载到网页中进行播放。所以避免这个问题社交云在上传过程中压缩视频,以便在网页中流畅播放和快速加载。压缩会降低视频质量,这也会降低最终用户的体验质量。在本文中,我们测量了社交云上不同标准视频文件格式的 QoS;它们在分辨率、音频/视频比特率和存储大小方面各不相同。
