<Quote: One analogue channel takes up as much bandwidth (8MHz) as a digital <multiplex. The number of digital channels on this multiplex can vary according to the <quality you want to get out of the resulting channels. For example, Sky Sports or <the movie channels are pretty high quality, so there aren't many to a mux, whereas <it's the opposite case for shopping channels.

And the new high-def broadcasts being trialled by Sky use 15Mhz of bandwidth, or twice that of existing analogue broadcasts for each channel! NTL will have to compete with Sky on High-Def so bang goes any ideas for using the freed-up bandwidth from switching off analogue...
If you try downloading any HDTV TV shows from the states, even though compressed using XviD and the resolution dropped to work on standard TV's, the quality is outstanding - better than DVD - and this is for TV recorded by home users onto their DVR's.
P.S. I got the idea of NTL digital being worse than freeview from posts to ntl.discussion.cable-tv.digital newsgroup and ntlhell.co.uk
