What is Multicast?

Multicast is way of streaming video over the Internet in an efficient way. For example all Aquiss Internet customers wanting to watch the BBC News stream can get the stream from Aquiss’s network rather than getting multiple copies from the BBC. This helps reduce the amount of bandwidth required by large organisations wanting to stream content to many users, and reduces costs to the ISP receiving that content too. This means that more streams of a high quality can be provided to many more people.

How does Aquiss provide Multicast?
Aquiss has enabled its ADSL gateways to allow you to receive Multicast streams from the BBC’s trial. In order to receive these streams you will need to have a compatible modem or router. Listed below is the hardware that we have tested with Multicast.

How do I watch Multicast video?
You will need a computer capable of playing Video and Audio together and for certain video formats the computer will have to be powerful enough to meet the media player's specification. The BBC are broadcasting their Multicast streams in the following formats: Realplayer 10 H.264 (QuickTime 7) MediaPlayer 9 To download any of these players follow the information on the BBC's web site, the page is linked below: http://www.bbc.co.uk/multicast/players.shtml

The BBC multicast service is a trial and as such Technical Support are unable to provide assistance with hardware configuration and setup. In all instances you should visit your hardware manufacturer's Web site or post on the Aquiss forum for help with Multicast setup.
