Financial Times: Bandwidth Wars, Thomas Hazlett
The vaunted digital television transition is under way. It offers to upgrade broadcast television picture quality. But high definition is mostly window-dressing. Indeed, television advertisers will not pay broadcasters much more for HD audiences, either because viewers watch on sets too small to notice it or because big-screen users subscribe to cable or satellite services for their HD fix. The real pay-off? Spectrum efficiency. What an analogue television transmitter can do using a standard television channel (6-8 MHz, depending on country) a digital station can do four, five or six times. Viewer choice increases multi-fold by flipping a technology switch. Digital’s cleaner use of airwaves also accommodates new voice and data applications.
