If you want to build a virtual tv channel from your existing content library, our channel playout system produces a very high quality live stream, as high quality as your content encoding can achieve.
Once your stream is built and running, submit a Scaleengine JSON feed url to Roku Direct Publisher. Your Roku app will show this live stream to your viewers. We recommend Tappla if you need Roku or Apple TV app development. We also recommend Instant TV Channel if you need a custom Roku app developed.
