iPods have had TV-out for years but the iPhone has always been left out. Now, however, the, firmware 2.2 has TV-out capabilities and it can send video selectively from certain applications.
Erica Sadun shows us the ropes.
The MPTVOutWindow class allows your iPhone to send its video to a connected TV rather than to the built-in screen. Intended to be used with movies, the unpublished class creates a live video feed that is sent out through the iPhone’s connector port. End-users will need to buy a video adapter or cable to use this functionality.
