I did mention that the safe area might exist or not, depeding on cable used, type of TV, where the user agent runs and other unpredicted conditions. It could run on an external device or on the TV itself. But I'm repeating myself.

You don't sniff for a cable, you sniff for the user agent of the browser that runs on the media device, which might or might not need a safe area and so on, which as you understand is *extremely* error prone and just an outright broken heuristic.
