Doug, from the Peoples Republic Of, visited Microsoft's IPTV booth at CES yesterday and got some more dirt on how the Xbox 360 IPTV will work. According to him, he found out that the IPTV service will be available over AT&T's 35Mbps lightspeed service which would allow for 2HD and 2SD channels to run simultaneously. Though the big problem here is that you'd have to replace your current ISP and cable provider to AT&T. And if you don't have access to the lightspeed service, then no IPTV for you! Secondly, you'll need a separate set top box that would work by itself or connected to a 360. So, the 360 still needs a separate set top box to use IPTV. Finally, if you have a home router it will need to be replaced by a special QOS (quality of service) router. Feeling sad yet?
Again, this isn't official information from Microsoft, but is information Doug received from Microsoft's IPTV booth at CES. Hopefully things will change before the roll-out, because the whole Xbox 360 IPTV service isn't sounding very good.
