1. eLecture Console.
Download: eLecture Console  (560 KB).
Students and Lecturer use this program to subscribe, participate and start lectures.

2. eLecture Server.

Attention: eLecture Server requires Microsoft SQL Server to be installed first! Any version of SQL Server is OK; we recommend installing free SQL Server Express 2005. This installation takes 3 minutes, simply click on the "Next" buttons; do not change any standard settings offered by SQL Server installation wizard. Then install eLecture Server and configure your first lecture!
Free version limitations: 10 concurrent user connections to the server.
Purchase an unlimited version.

3. Unreal Live Server.
Download: Unreal Live Server (1.2 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, MP3, GSM 6.10 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 UM100 and UM200 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.

4. Screen Capture DirectShow source filter (optional).
Download: UScreenCapture (174 KB).
You may need this component for whiteboard functionality, to stream your desktop as a part of your lecture. It needs to be installed on the computer where the Live Server is installed. Capture frame rate and desktop region to capture can be configured. Dual-monitor systems are supported.
