Released to developers along with the iOS 7 beta, Apple TV software update 5.4 beta 1 brings some new features to our little black boxes: a long-awaited iTunes Radio, Conference Room Display option, automatic updates in the background and customizable subtitles.

You can set a custom message and a background image. The instructions are then displayed as a screensaver.
