Although not addressed during yesterday’s media event, the Apple TV is scheduled for a software update on Sept. 18, AllThingsD reports. One new feature in the update will let users stream their purchased iTunes content to another user’s Apple TV using AirPlay. The content will stream directly from the cloud to an Apple TV — it will no longer be necessary to download the content to an iOS device to send to the TV. It’s also likely that the update will contain iTunes Radio, Apple’s new music exploration service. The software update will be released the same day as iOS 7.
