Silverlight Smooth Stream is a new format of playing HD video on the web
Silverlight is an exciting new high-tech technology from Microsoft, that's best described as a more sophisticated version of Flash, its the future of the internet. It detects your bandwidth speed, computer processor power and screen size, then plays the best quality of video possible as a constant stream, changing bandwidth when needed without stopping to buffer, i.e. "smooth stream".
For those of you that don't have high speed broadband, but still want to watch the highest HD quality, you'll see the manual bit-rate selection tabs are available in 300K, 1.5Mbps and HD 4Mbps. But you may have to wait for the video to buffer before playing.
All new PC's will come with the Silverlight web browser plug-in pre installed. If you have an older PC or Mac, then you'll need to install the Silverlight plug-in. It only takes a few seconds to install and works on all web browsers including Firefox.
