USA Today explains that three guys in Berkeley came up with a crazy notion back in 2003 -- MobiTV. It proved that (some) cellphones were powerful enough to display television images. It wasn't great TV, but it moved...at a frame or two a second.

In November 2003, Sprint became the first wireless carrier to offer MobiTV to consumers. The $10-a-month service, now also offered by Cingular, has attracted 500,000 subscribers. Verizon's competitive service, V-Cast, utilizes their faster EV-DO cellular data network to deliver video clips, games and music for $15/month.

But using a cellular channel to deliver multi-media doesn't really pencil out. There just aren't enough channels. Multicasting, like broadcasting, is the ticket. Millions can receive programing over one channel with multicasting.

Technologies like Qualcomm's MediaFLO and Crown Castle's DVB-H offload mobile video on a separate channel outside the cellular band. MediaFLO will use 700 Mhz while DVB-H will use 1.6 GHz to deliver mobile video across the United States in a year or so.

Today, Qualcomm announced the first live, over-the-air demonstration of FLO (Forward Link Only), delivered to a wireless handset.

FLO Technology, a multicast technology, is lots cheaper. Qualcomm says it requires only two or three broadcast towers per metropolitan area -- that's 30 to 50 times fewer towers than required by traditional cellular systems. Operators can provide live streaming video channels (QVGA resolution at up to 30 fps), to millions. Short "clipcasts", audio, and data channels are planned.
