Media servers

Real Server
Realnetworks media server was originally designed  for slow and congested connections like dial-up modems but now it can also transfer fairly good video quality for broadband audiences. The most used compression method is proprietary. Basic free player is available for most popular operating systems like Linux, MacOS and Windows. Netscape browser is often preinstalled with it. It can also support several competing audio and video formats. You can control the playout of the multimedia streams according to RTSP and SMIL standards. For more information please see manufacturers homepage.
Quicktime Streaming Server

This is a streaming server based on open standards like RTSP, RTP and HTTP. Since it's developed by Apple it comes as standard with MacOS X servers and it supports the Quicktime file format that can contain many kinds of streams. A proprietary Sorenson codec has been quite popular but Apple has also launched a new ISMA standard MPEG-4 codec support. More information can be found from the program homepage

Darwin Streaming Server

Apple supports the development of a Open Source streaming server within the Darwin project. It's basically the Quicktime streaming server adapted to other operating systems like Linux, FreeBSD, Solaris and Windows. We have for example successfully used it to relay multicast RTP/H.261 streams to Quicktime users from the Finnish parliament. More information can be found from program homepage.

Kasenna Mediabase

Kasenna (formerly SGI) Mediabase is especially designed for delivering various MPEG formats in real time even for large number of users. The older versions do support also quicktime and Realmedia files, the newest one ISMA MPEG-4 and Windows Media. For more information please check our Mediabase server's original documentation or the manufacturers homepage.

Windows Media Services

Mediaserver designed by Microsoft for their server line of operating systems. It uses their own propriatary protocols and formats. Windows media player is used as the client. Since there's no linux/unix client or server available we haven't used it in our production server environment although some successfull pilot tests have been done. It's best suited in a Microsoft only environment where it's relatively easy to deploy and manage. For more information please see the product homepage.
