摘要
流媒体是指在互联网中使用流式传输技术的连续时基媒体,与传统的单纯下载相比较,流媒体具有明显的优点:不需要将全部数据下载,因此等待时间可以大大缩短;由于流文件远远小于原始文件的数据量,并且用户也不需要将全部流文件下载到硬盘,从而节省了大量的磁盘空间;采用了RSTP等实时传输协议,所以更加适合动画、视频音频在网上的实时传输.本文主要介绍流媒体的技术特征、基本原理及其实际应用.
Streaming media is the continuous time based media applied in Internet/Intranet. Comparing with traditional download mode, it has a lot of advantages: less waiting time due to completely download all data is unnecessary; small streaming file to save disk space, etc. The RSTP and other real time protocols are more suitable for the real time transmission of cartoon or AV signal. The characteristic, principle and practical application of streaming media technology have been discussed.
