Apple composite AV Cable with authentication chip.

The new iPod Classic, Nano with Video, iPod Touch and iPhone will only enable video-output when attached to a cable with a Apple Authentication chip inside. Notably, the new iPods are each capable of a higher maximum 480p resolution of video output than last year’s video-ready model and so investment in this cable or a docking unit is worthwhile to get near-DVD video onto your TV.
This is an attractively designed 6-foot audio-video cable designed to connect video-capable iPods and the iPhone to standard-definition television sets, using metallic component RCA plugs on one end, and a Dock Connector on the other. Includes USB power adapter.

Apple’s Composite AV Cable is designed for use with virtually any television set produced in the last 10 years, and many released before that. It contains a set of three RCA-style connectors—left and right stereo audio, plus a single yellow composite video plug—in addition to a USB plug for charging. The video and USB connectors are separated on the cable from the audio plugs for easier connection to separate devices.
USES
Connect an iPod or iPhone to your television with the Apple Composite AV Cable, gather up your friends, and watch videos or slideshows together on the big screen. You can also connect the Composite AV Cable to your stereo or powered speakers for a room-filling audio experience.
The Composite AV Cable connects to your iPod, iPhone, or Universal Dock via the 30-pin dock connector and to your TV, home theater receiver, or stereo receiver via the composite video and red/white analog audio ports. The cable also features a USB connector that you can plug into a power source, such as a computer or the included USB Power Adapter.
