Adding this feature could make the iPad and iPhone very attractive options for video streaming sources.
If you're not an iPhone or iPad owner, you probably haven't paid much attention to AirPlay. It's a cool idea that currently has fairly limited functionality. A device with AirPlay can stream audio directly from your Apple device without the need for a complicated setup.
AirPlay is currently found on a range of devices from iPod docks to receivers from companies like Denon and Marantz. Rumor has it that Apple is going to go one step further and bring AirPlay to televisions.
To accompany that, there's word that Apple will begin incorporating video into AirPlay. That means that with an AirPlay enabled TV, you'll be able to stream audio and video from your iPhone, iPod or iPad without having to go through any complicated setup.
