Wi-Fi video transmitter
Princeton has launched its PCK-UAV wireless video transmitter intended primarily for Apple's fifth-generation iPod. The adapter plugs into the iPod's headphone jack to relay music, photos, and video through UHF channels to a compatible TV, such as many in-car models already available in Japan. The transmitter includes an iPod cradle and a special cable; although the hardware's use of standard RCA jacks allows for DVD players or virtually any other video source to broadcast a signal, according to Electronista. The PCK-UAV ships within the next few days in variants with and without an iPod mounting kit from $90.

Headline Misnomer
Having gone to the Japanese site, I believe that the use of the word "Wi-Fi" in this article headline is a misnomer.
The unit takes the output of the iPod and transmits it via a UHF channel to a TV mounted in a car with a UHF tuner. So it is not "Wi-Fi", nothing digital about it, just plain old loop-antenna UHF technology and can be received by any TV that has a UHF tuner.
The Electronista article correctly describes the unit.
