WebELecture needs to be installed on a computer running IIS web server; it can be installed on the same computer that runs eLecture Server, or on the separate one.

3. Unreal Live Server.
Download: Unreal Live Server (1.3 MB).
If you want to broadcast audio/video with your lecture then you need the Live Server that encodes and streams live audio/video sources in WMA, AAC, MP3 audio and VC1 (WMV9), H264, MPEG-4 video formats. Use Live Server configuration tool to setup streaming sources and specify encoding parameters. Then you will be able to import Live Server configuration to eLecture for setting up streaming feeds associated with your lecture. The Live Server can be installed on the same or different computer relative to eLecture Server.
Our UM300 and UM400 hardware streaming devices can be used instead of Live Server, providing more reliable, hardware-encoded audio/video. These devices eliminate the need in encoding computer; essentially they replace the "camera + encoding computer" set.
