A Half-Dozen Ways to Get TV on the Go

Cell carriers, satellite companies, and local broadcasters are all peddling mobile TV.

DirecTV Sat-Go.

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.
