If you have an 8meg ADSL line and want to deliver IPTV you need some kind of
preferential treatment to the TV packets on this access line to ensure
quality, for instance in the case of the user doing a file transfer at the
same time they're watching TV.
Provided that IPTV or VoIP are the only [large] datagram streams in
progress, this is not difficult to do on the CPE end -- in fact, this sort
of thing is already available as a QoS option in some home router
appliances. It involves scaling back TCP streams so that they leave enough
headroom for the in-progress IPTV or VoIP.
