PSP and One-Seg?

(tags video, PlayStation Portable, digital broadcast, Japan)

You know what would be great is if the PlayStation Portable could act as a One-Seg digital television tuner. Sorry if this isn't an original thought, yeah, people have been thinking about that since One-seg launched last year. Here's the latest rumor, 2006/12.

Anyway, I wonder if it is technically possible. Right now there's no hardware. Is the PSP fast enough (has dedicated chips or software emulation) for the digital broadcast? According to the specs, yes it can decode the MPEG-4 AVC streams that One-Seg mandates. Let's see, 320 x 240 video on a 480 x 272 screen. Ugly?

Perhaps with Sony's release of the 3.30 firmware which allows full-screen user converted video, Sony seems to be giving up on the UMD format push. Perhaps this will lead to development on One-Seg hardware? Then again, they are still forcing PS1 games for PSP downloads through the PS3, and there's also LocationFree. To add a final blow, why would you need it for the PSP when you can buy mobile phones that show One-seg Digital TV?
