With TradeCast's OTT application for Apple tvOS you can offer your online video platform as an OTT application in the Apple TV App Store. The application's contents are based on your web-based video platform, so you only need to upload your content once to make it available to viewers on Apple TV.
Managing content to become visible in your Apple TV app works the same as making content available on the web-based version of your own video platform: by providing a video - through the Media Overview - with a current publication date, this video will also appear for viewers of your video platform app for Apple TV.
Note: it is not possible to have uploaded videos only appear for viewers of your Apple TV app.
