Verizon's VP of network architecture admitted the company's IPTV technology isn't ready for a full IPTV deployment, at least until 2007. Verizon, to hasten its quest for early revenue, "didn't want to wait, even if we could do it in stages," he said. "Technically speaking, the problem is getting highly scalable IP multicast. Nobody has ever built an IP multicast network on that scale before." Much like the cable industry, Verizon is presently using an RF overlay to deliver video services, but running IPTV to the home is on its way, someday. Article
