More Power! Years ago, I was told that there were several ways to rate the power output from an amplifier, but only one of those ratings was the "true" measureRMS or continuous power. The Federal Trade Commission (FTC) got into the act back in the 1970s, requiring all amps over 5 or 10 watts to be rated in RMS watts with both channels driven. That requirement was lifted in the '80s, and now when I read power output specs, I don't know if they are RMS (root mean square), IHF (Institute of High Fidelity), or something else. Could you clarify this confusion?

Last Sunday, my wife and I joined 25.8 million of our closest friends to watch the 52nd Annual Grammy Awards on CBS. So why am I writing about it here? Because this is <I>Ultimate AV</I>, and the Grammys are all about the best in audio <I>and</I> video. The audio part is obvious—this is "music's biggest night" honoring the best recording artists, and all the performances are live, a technological tour de force in its own right. But the show is no less dedicated to video, both on stage and in the home.

On June 11, 2009, I lost a cherished friend: the Sony Watchman TV I'd owned for 20 years. When analog TV broadcasts went dead that day, my Watchman, along with every other portable analog mini-TV, suddenly became useless. A few portable digital TVs have since appeared to fill the gap, but because the ATSC digital-TV standard wasn't designed for mobile use, none of them can deliver the reliable roving reception of my 1980s-vintage Watchman.
