提到媒体,大家马上就会想到报纸杂志,广播电视。要说起现在刚出现的一个新名词—流媒体,一些人可能会认为它同平常我们所说的媒体有某种关系。其实,所谓的流媒体同我们通常所指的媒体风牛马不相及,它只是一个技术名词。流媒体到底是什么?又能给我们带来什么呢? 随着宽带成为网络架构的重点,网络上的信息不再只是文本、图像或者简单的声音文件,流媒体(Streaming Media)由此孕育而生。流媒体不同于传统的多媒体,传统多媒体文件需要从服务器上下载之后才能播放,一个一分钟的视频文件,在56K的窄带网络上至少需要30分钟才能下载到本地硬盘。而流媒体的特点是运用可变带宽技术,使人们可以在28K到1200K的带宽环境下在线欣赏高品质音频和视频节目。
Mention the media, we will immediately think of newspapers and magazines, radio and television. To talk about a new term emerging now - streaming media, some may think it has something to do with the usual media we speak of. Actually, the so-called streaming media is irrelevant to the media we usually refer to. It is just a technical term. What is streaming media in the end and what can we bring? As broadband becomes the focus of network architecture, the information on the network is no longer just text, images or simple sound files, and streaming media is born Health. Unlike traditional multimedia, traditional multimedia files need to be downloaded from the server before they can be played. A minute of video files takes at least 30 minutes on a 56K narrow-band network to download to a local hard drive. The streaming media is characterized by the use of variable bandwidth technology, so that people can enjoy high quality audio and video programs online in the 28K to 1200K bandwidth environment.
