Introduction
	The Helix Universal Media Server is the only universal platform with support for live and on-demand delivery of all major file formats, including Real Media, Flash, Windows Media, QuickTime, MPEG 4, MP3, and more. It also accepts live encoder connections for these file formats, increasing content creation flexibility and preserving investments in automated encoding systems. A full or 30-day trial version of the software is available.
	Installation
	Connect to your Virtual Private Server via Telnet or SSH and complete the following steps. Download the Helix Universal Server software. FreeBSD [Helix Universal Server] The software is found at the RealNetworks Web site. Be sure to select "FreeBSD" as the server Operating System! Download Helix Universal Server Create an install directory for Real Server. Issue these commands while connected to your server via Telnet or SSH: % cd % mkdir ~/usr/local/real Upload the Installation software (in BINARY format, if you are using FTP) to this new install directory. If you entered the registration information correctly when downloading the software, a Real Server Evaluation license key file will be e-mailed to you by RealNetworks. RealNetworks offers the following advice for uploading your license key: Your license file for your Helix Universal Server will be corrupted if it is transferred from one computer to another via FTP as a text document. Doing so will cause changes in the file to the degree that the checksum the Helix Universal Server runs on the installed license file at startup will fail, and the Helix Universal Server will not start. The file can be successfully transferred via FTP as a binary document. Run the setup utility by issuing the following commands (the example is the file for FreeBSD installation. Change the filename to the name of the file you downloaded from RealNetworks): % cd ~/usr/local/real % chmod 755 rs900-freebsd4-ia32.bin % ./rs900-freebsd4-ia32.bin The installation program will now run, stopping when it needs further information (outlined below).
