Though Apple made no mention of the Apple TV update when announcing the forthcoming launch of iOS 4.2, the software arrived at the same time, around 10 a.m. Pacific, 1 p.m. Eastern on Monday. The Apple TV software update can be initiated through the device's settings menu, and is done directly over a wireless or wired Internet connection.
In addition to AirPlay, which will allow streaming of video and audio from iOS devices to the Apple TV, the 4.1 update also brings VoiceOver functionality. The new feature can be turned on through the accessibility menu of the Apple TV.
VoiceOver reads menus and metadata, including episode descriptions for TV shows. In the settings, users can also set the speed of voice playback.
The Apple TV 4.1 software update automatically enables AirPlay without password protection. If users choose, they can turn AirPlay off entirely through the settings menu, or can add a password to limit access.
AirPlay is built in to iOS 4.2 for the iPhone, iPad and iPod touch. It allows users to stream video or audio content directly to the Apple TV over a Wi-Fi network. Users can also directly stream music to an AirPort Express.
