Nintendo DS Digital TV Tuner

The Nintendo DS Digital TV Tuner is a DS Terrestrial Digital Broadcast Receiver Card (TV tuner) for Japan's digital TV. It uses a service called 1seg in Japan. Some of cell phones are capable of receiving the broadcasts also. The top screen is the TV broadcast and it's only being used for digital TV, the second screen of the Nintendo DS is used to switch channels. The prototypes Nintendo had at the press conference ran via the Game Boy Advance cartridge slot, but the final version of the card plugs into the DS card slot. The TV tuner was released April 2007 in Japan. The card features a built-in Game & Watch game, Game & Watch Fire. The TV Tuner is not scheduled for release outside of Japan because Digital Broadcasts are planned to be replaced by cable.
