One of my earlier posts in this thread said that, I made a comment about it being suitable for VOD or if we change our view and considered it a VOD type service instead of broadcast.
Yes, the set top box can only display one channel at a time, but currently the customer has facility in many cases to watch one channel, record one of the off air bypass channels and surf the net at the same time. This will be impossible with the current bandwidth available down DSL.
I understand (from BBKing) that improvements have been made in bandwidth available over ADSL, and I assume it could now be possible to have 2 or 3 different services running on the available bandwidth.
I assume much of this has been made possible by clever Error correction, Software and protocol changes to overcome the shortcomings of the twisted pair.
ADSL is a method of making a silk purse out of a sows ear, there will only be so far they can go with software changes/fudges until they need to start upgrading the distribution network.
Time will only tell if higher bandwidth services over BT's ancient twisted pair network will be relaible and just as importantly available to the mass majority of householders. Even some people within the required distance of an ADSL enabled BT exchange are still not able to get ADSL service!
