UHD supports the Real Audio/Video (.ra and
.rm) format for streaming audio and video over the Internet. We
use RealMedia’s Helix server product with a cache system
to stream audio and video. RealNetworks server software is used
to stream multimedia presentations to a RealPlayer.
Player Standards
An updated player from RealMedia is required to view UHD streaming
material. One can obtain a Real Player from RealMedia at their
website. http://www.real.com/freeplayer/?rppr=rnwk
If you have Real Player on your computer go to the update section
and download the latest version. RealMedia players are available
on most operating systems. The current Real Player 10.5 will work
on Windows 2000, XP, OS 10.x and Unix operating systems. Visit
www.real.com
for more information.
Encoding Standards
UHD ITV/Multimedia typically produces Web video in two RealMedia
standards: one for dial up and one for broadband. We use the Variable
Bitrate encoding method, to ensure higher rates of playback. We
also use SureStream, a technology that lets a single video clip
stream at different bit rates. It does this by bundling a single
clip into multiple streams, each of which runs at a different
bit rate. In-house Web videos for UHD may be encoded at higher
transfer rates.
If your video file is in a different format
than a realmedia file. (ie): AVI, Mov, MPEG, WMF or other. UHD
ITV/Multimedia Media Services provides broadcast quality video
services that can encode or transcode your file into a RealMedia
file. Pre-recorded material on VHS or DVD provided by faculty
and staff can also be encoded for distribution on the Web.
Support Standards
If you have met all the above standards and are still not able
to view the scheduled streaming program, contact user support
services at x3000 for on-campus users. For off-campus users, contact
your Internet service provider for additional help.
