We can't imagine this working very well, but Princeton Japan will soon be shipping its PCK-UAV video transmitter, letting you plug in any device with audio and composite video outputs using an RCA jack, whose signal is then transmitted to any TV receiver tuned to the UHF band.
Targeted at iPods, it's designed to eliminate the need to deal with cables and plugs into your television set. But then, you'll need to deal with cables and plugs with your iPod. If this works like FM transmitters for iPods to car radios, this is not going to be worth the $70 tariff for owning one.
And please, do the rest of us motorists a favor and don't use it as indicated in the illustration above to watch videos while you're driving.
