Does Channels integrate with the Apple TV app?

Does Channels into the Apple TV app? If not, will this be supported in the future?

I'd really like to use the Apple TV app to view all my streaming content and my local content (i.e. Channels + HDHomeRun) through that one single app.

No, Apple currently does not provide any APIs for third-party apps to integrate. It is only available to their select big-brand partners.

OK - That's what I figured. Thanks!
