Just launched in Japan, Sony’s got high hopes for its 1-SEG digital TV tuner — and with over seven million Japanese PSPs now capable of viewing high quality video over the air (complete with EPG), we can’t blame Sony for it’s optimism. The only way you’ll get one of these, though, is if you pack your sorry self up and move on overseas — or find a way to set up a pirate 1-SEG cell, anyway. It’ll might just be worth it though, the whole mobile TV experience we saw on this tuner was pretty smooth, with near-instant channel changes and that slick guide, to boot.
