Flick the Switch

Being the avid rugby fan that I am, I tried to watch the Tri=nations game between Australia and South Africa on Sky Sports 2 on Saturday.

However, the image quality was so poor that the game was unwatchable. It looked like a 500Kbps Windows Media stream.

This just goes to show the problems that the TV delivery companies are facing as they add more channels - and especially as they add bandwidth hungry HD channels.

The answer is to change from an 'always on' switched delivery network, where a few hundred channels are 'always on' for every viewer to a 'server switched' model whereby only one channel is delivered to a customer and this is then switched at the server end when the viewer wishes to change channels. Tens of thousands of channels can be made available to any viewer.
