How do I make my content available within the TV App, and know when my app is being opened from within the TV App?
These are good guidelines on the user experience, but I can't find any APIs, frameworks, or any documentation whatsoever for implementing these workflows.
Am I totally missing the boat somehow, or can someone point me to this documentation?
