In what eerily resembles the hype over VOIP, there is growing enthusiasm for IP-TV. Infonetics Research expects IP-TV service revenue will jump to $44-billion by 2009 while the number of subscribers will climb to more than 53 million. The investment required to get this business is starting to pick up momentum - climbing to $4.5-billion in the next four years from $304-million in 2004. So far, Infonetics said a lot of the spending has been on DSLAMs, edge routers and aggregation switches but service providers will need to focus on major investments on VOD servers, encoders and head-end equipment. The Infonetics report comes a couple days after Telus Corp. said it has launched IP-TV (over ADSL) in Edmonton and Calgary following an extensive testing program. For all the optimism about IP-TV, a key consideration will be how it will be different from cable-TV. A $53-billion market in the next four years will not materialize if there is a lack of compelling bells and whistles for consumers. Telus, for example, is hoping it can maintain financial discipline (a.k.a. non-discount prices) to win IP-TV market share. While the carrier hasn't provided many details, its IP-TV service will give consumers the ability to customize their programming. Hopefully, this mean you don't have to take crappy channels within a package just to get "good channels" such as A&E.
