Nintendo announces a digital TV Tuner card for the Nintendo DS portable game system in Japan.

The Nintendo Digital TV tuner card will come in April when in Japan terrestrial digital TV launches.
The second screen of the Nintendo DS comes in handy and is used to switch channels.
It is questionable if watching TV on the Nintendo DS will be supported in other markets. Yesterday we reported about a 4GB HDD with media player for the Nintendo DS. The Nintendo DS is catching up (see the news about the DS browser) in terms of non-gaming features to the Sony PSP. I think though Sony has a stronger media concept with UMD videos and built-in music and video player.
