MacRumors is reporting that a new feature is beginning to show up on the latest generation Apple TV called Live Tune-In. The feature, described on an Apple TV splash screen, lets you use the Siri Remote to access live streamed media available in certain Apple TV apps. According to MacRumors:

To use Live Tune-In, Apple TV users can speak into the Siri Remote using commands like “Watch CBS,” or specifically ask to “Watch ESPN live.”

Little by little, the Siri Remote is becoming a more powerful tool for quickly navigating Apple TV apps in a way that is not unlike the evolution we have seen with Siri on iOS.
