The 1seg tuner for PSP makes us jealous of Japanese PSP owners. The tiny peripheral attaches to the top of the system, and allows users to tune into a variety of broadcast channels. The video quality at the Tokyo Game Show floor was stellar, with very minimal artifacting seen in the video. It's easy to change channels through a simple intuitive interface which overlays over the video quite nicely. A variety of video resize options can be readily accessed by bringing up the options menu with the Triangle button.
If there's a complaint we would have about the 1seg tuner, we'd say it has to be the delay that comes when switching channels. It takes a full second or so for the system to display video of the next channel. Certainly not a major hindrance, especially when considering the quality of video that's produced on such a small peripheral. Japanese Joystiq readers will want to check it out.
