The worldwide cable TV industry is in a race to provision a “three-screen” service that starts with HDTV sets, maps over to broadband-connected PCs, and follows subscribers around during the day on cell phones or other portable devices, reports In-Stat. The company expects strong, continued growth in cable TV infrastructure equipment with sales rising from about $925.4 mln during 2006 to more than $2.1 bln in 2010.
