一些概念

1. shoutcast: http://en.wikipedia.org/wiki/SHOUTcast   繁体版：http://zh.wikipedia.org/zh/SHOUTcast

　　SHOUTcast是由Nullsoft研發、支援多個作業系統、免費的聲音串流科技，用於網路廣播。

　　SHOUTcast使用MP3或是AAC將聲音編碼，由HTTP作為傳送協定。

　　SHOUTcast的使用者可建立自己的網路廣播電台，許多軟體都可以收聽該廣播輸出的格式，包括Nullsoft Winamp、XMMS，以及蘋果電腦的iTunes。目前可作的用途包含了聽音樂、看影片以及收聽現場直播。  

　　最常見的用途就是以SHOUTcast製作網路廣播。比起傳統的AM調幅或FM調頻廣播，SHOUTcast不僅便宜，技術門檻也較低，更不受到政府管理頻譜的影響。同時，傳統的廣播電台也利用SHOUTcast將版圖延伸到網路上，讓聽眾在收不到電波的地方（例如地下室）或是地下電台蓋台嚴重的地區仍可利用網路來收聽。

 

 

 

2. Icecast：http://en.wikipedia.org/wiki/Icecast     

　　Icecast is a streaming media project released as free software maintained by the Xiph.org Foundation. It also refers specifically to the server program which is part of the project. Icecast was created in December 1998/January 1999 by Jack Moffitt and Barath Raghavan to provide an open source audio streaming server that anyone could modify, use, and tinker with.^[1] Version 2 was started in 2001, a ground-up rewrite aimed at multi-format support (initially targeting Ogg Vorbis) and scalability.

Technical details

    The Icecast server is capable of streaming content as Vorbis over standard HTTP, Theora over HTTP, MP3 over the protocol used by SHOUTcast, AAC, and NSV over the SHOUTcast protocol. (Theora, AAC, and NSV are only supported in version 2.2.0 and newer.) It uses external programs, called "source clients", to originate the streams, and the Icecast project includes a source client program known as IceS. The source runs typically in the place where the audio is generated (e. g. a studio) and the Icecast server in a place where a lot of bandwidth is available (e. g., a colocation).

It has similar functionality to the proprietary media server program SHOUTcast, by Nullsoft.
