Real Audio/Video is included free with all accounts. Real Audio is a real time audio transmission/player system. A digital audio stream is transmitted from the server over the Internet to the destination and played immediately, rather than being stored to disk first and then played.

Each audio/video clip requires two files: a metafile with extension .ram, and the digital audio clip itself, with extension .ra or .rm.

The .ram file holds one or more lines of ASCII text, each of which references the .ra file to be played when the .ram file is accessed by the browser. Entries in .ram files have the form:
      pnm://servername.host4u.net/yourdomain/name-of-clip.ra
or
      rtsp://servername.host4u.net/yourdomain/name-of-clip.ra
(where "servername" is replaced with the name of your server, you may lookup the name of your server here).

The .ram file may be placed anywhere in your www directory. The binary clips MUST be uploaded to the 'realaudio' subdirectory, which is located in your www directory. When you access the .ram file through a web browser (http://yourdomain.com/yourfile.ram) it will tell the server where to look for the clip, and if you have RealPlayer installed on your computer, the Realaudio/video clip should start playing right away.

Important: In order to use the G2 features such as multi-rate SureStream and Slide Presentations (.smi), You must use rtsp:// in the .ram file. The metafiles (.ram) must be uploaded in ASCII mode while the clips (.ra or .rm) must be uploaded in BINARY mode.
