A small but significant change being brought to iOS 8
is peer-to-peer AirPlay connections between iOS devices and Apple TVs, Apple's official website reveals
. At the moment, iOS devices wanting to broadcast to an Apple TV have to be on the same Wi-Fi network. That presents a problem, though, if a person doesn't have access to login credentials or a LAN is offline or simply non-existent.
Apple has yet to explain how the technology will work, but it's likely that devices will discover each other through Bluetooth and form direct Wi-Fi links, much like AirDrop. The same concept could conceivably be applied to Macs using OS X Yosemite, but Apple has yet to mention any plans in that regard.
The feature will also presumably require an update to the Apple TV firmware. The set-top has been rumored as getting both a firmware and a hardware refresh sometime this year, but neither was on display at yesterday's WWDC keynote.
