You can already find PlayStation Vue, Sony's proprietary streaming service, on most every device in your living room. It's native on the Playstation 3 and 4, available on Android TV, Roku boxes, Fire TV and Stick, not to mention compatible smart TVs. You can also find it on Android and iOS devices as a mobile app, which can be streamed to Chromecasts. Today, that ecosystem grew a bit more with the announcement that Vue is now available on Apple TV as well.
Vue's UI and features like cloud DVR won't change from what you're used to but it will take advantage of Apple TV's hardware including the Siri Remote and touch navigation. You'll be able to stream live television and sports plus gain access to premium channels like HBO and CInemax, if you don't already -- you simply need to link your Vue and Apple TV accounts. Vue offers a bunch of different channel packages and a la carte options so head over to the Vue website for more details.
