HbbTV-Association/ReferenceApplication ? reverse-engineered prompt

Build me a reference video catalogue and player app for HbbTV devices that can browse test content and play DASH video streams.

I want it to support both HbbTV 1.5 and 2.0 devices, and also work on devices that need a browser based player fallback. The app should let me browse a simple catalogue, open a video, and test things like DRM protected streams, clear streams, audio track selection, subtitles, cue data, live and VOD playback, and multi period streams. It should also have a way to test ad insertion, including pre roll and mid roll, and show clear playback status and errors when something goes wrong.

Please make the catalogue data driven so the menu and items come from a config file, and keep it easy to change the source content later. If you need to, look up the current HbbTV and DASH docs online before you build it.
