tvOS multi video channel template

I’m new to building tvOS apps, and really need an example app built to present user with multiple video channels/feeds, allowing user to scroll through vids available within each channel/feed, then select a vid to play within selected channel/feed.

I’ve already developed such xml vid feeds for our Roku TV app, so I could easily adapt those for a tvOS app.

Anyone know of such a multi-channel video tvOS app template out there?
