From Unreal Streaming Technologies:
Unreal Media Server is a software streaming server offering rich choice of live and on demand streaming functionality. It streams with variety of streaming protocols to deliver content to Flash Player, Silverlight, Windows Media Player, Unreal Media Player, mobile devices and Set-Top boxes. The server supports UMS (our proprietary, DirectShow-based, codec-independent) protocol for streaming to Unreal Media Player in Unicast and Multicast modes; RTMP and RTMPT protocols for streaming to Flash Player; MS-WMSP and MS Smooth streaming protocols for Silverlight and Windows Media Player; Apple HTTP Live streaming protocol for iOS and other HLS-enabled devices; MPEG2-TS protocol for streaming to Set-Top boxes. Unreal Media Server streams ANY multimedia file format, encoded with ANY codec. Supported container formats include but are not limited to: MP4, ASF, AVI, MKV, MPEG, WMV, FLV, OGG, MP3, 3GP, MOV. Files can be unicasted in "on-demand" mode or multicasted in "live" mode. Playlist functionality is supported. Unreal Media Server supports ingesting live streams from wide range of live software and hardware encoders that send streams over RTMP, RTSP, MPEG2-TS, MS-WMPS and UMS protocols. Incoming live streams can be instantly served to various players via two live streaming delivery modes: Near-Real-Time and Buffered. Conferencing applications can take advantage of 0.2 - 2 seconds latency provided by Near-Real-Time mode. Supported live encoders include: RTMP hardware and software live encoders such as FMLE; RTSP and MPEG2-TS software servers and encoding devices such as IP cameras and broadcasting equipment; MS-WMSP encoders such as WME; Unreal Live Server which is our proprietary live audio-video encoder. Unreal Live Server supports any possible capture device attached to a PC, such as USB digital camera, microphone or capture/TV-tuner card. Unreal Live Server encodes captured audio-video with H264, VC1, AAC, MP3, WMA codecs and streams it over UMS protocol to Unreal Media Server. Unreal Live Server and Unreal Archival Server can also record live content based on schedule or motion detection, independently of streaming, into ASF and MP4 files.
