US Mobile DTV standard finally approved

Well freaking finally. The Advanced Television System Committee just approved the Mobile DTV standard, meaning we're finally about to see for-real mobile television in the US. LG and Samsung have already made gear for the new standard, and the tech will be demoed later today before a rollout... sometime. Still, it's heartening news to hear that it's finally ready -- over 800 stations are signed up to broadcast the new signal, which makes use of existing 6MHz airwaves to do everything from straight TV to video-on-demand and targeted advertising. Cool, so now we're what, just a billion years behind DVB adoption?
