DS TV Goes on Sale in Japan
The little heard-of television adapter for the DS went on sale in Japan yesterday, retailing for ¥6,800 ($62.70). "The design is different from the prototype shown in 2004, as it features a simple aerial cartridge which plugs in the back of the handheld, and no base unit. The top screen is used for the TV picture, while the bottom screen can be used to do things such as change channels and take notes." The company has no current plans to bring the TV adapter to the US, or anywhere else.
Maybe because it's a 1-seg tuner there are no 1-seg broadcasts outside of Japan. Why would you want it in the US or Europe if you can't even tune to any channels?
It's a digital 1-seg tuner, which just receives an unencrypted 320x240 version of the HDTV signal.
