[Doit.wisc.edu] (Dial-up Internet service providers don't support multicast either, but they don't have sufficient bandwidth for television, so the multicast issue is moot in this case.) As a result, IPTV multicast channels will not be available over DSL or cable modems. On-demand programs use unicast technology, so it is possible to view on-demand programs over DSL or cable modem technology if the bandwidth is available (I have tested this on Charter cable modems at home, and it works).

[Blogmaverick.com] Broadcast TV will never die. - Blog Maverick - www.blogmaverick.com _: When a file or live event is multicast, rather than having a copy of the program delivered, uniquely from each source to each destination (unicast delivery), the stream of bits is replicated through the routers on the network so that one copy exists on the network at any given time.

Set top boxes suddenly speak IGMP to tune into program channels and SAP/SDP-style announcements/EPGs (more general: Internet Media Guides, IMGs :-) gain importance.

Viewers should be able to listen to their voicemail through their TV, read their SMS and MMS messages, send picture messages so they appear on the TV screen (and subsequently forward to friends, other email accounts etc), view their account details, buy accessories they can send to their phone directly (backgrounds, ringtones, games etc) and optionally display their location in the world if their phone is programmed to allow it.
