Sat-Go: Satellite TV now travels in a briefcase. The lid must stay aimed at the southern sky, meaning it can't be on the move while you're watching. And the system weighs 27 pounds, so it's not meant for carrying around. But while on a tailgate, it offers all the sports, movies, and sitcoms that DirecTV offers. Sat-Go comes with a 17-inch LCD screen for viewing. Lining up the antenna can be tricky, especially if there are tall obstacles nearby. And don't venture far, as the battery can die in an hour. Cost: $1,000 plus monthly subscription fee. Or if you want 185 channels while on the go, consider the $3,000 (plus subscription fees) TracVision A7.
Mobile Broadcast: By next year, this new standard could deliver broadcasts from local tv stations to hand-held devices. Stations are expected to simulcast local programs and offer extra, cablelike channels. Some willbe supported by advertising; some will carry monthly fees. The first of the devices could appear in 2009 as hand-held media players but can be built into navigation units, laptops, and cellphones. The experience should be like that of Flo TV, which uses similar technology, with TV-like viewing and reception issues, depending on a handset's position.
