MediaFLO was demonstrating their live television solution for wireless, and it was quite impressive. The company doesn't make hardware, but rather transmits audiovisual content across their own nationwide network. Service providers working with MediaFLO can then offer the content to their customers; MediaFLO has powering Verizon's Cast service for a year or so now.
A rep showed me a Qualcomm handset (MediaFlo is owned by Qualcomm) playing TV content, and she flipped through the channels just like you do on the couch at home. The image was clear and sharp, audio was in sync, and Prison Break looked just like it does on TV (but smaller). Expect news from MediaFLO this year as the battle for your cellular entertainment dollars heats up.
