Indeed as soon as the box is connected and powered up you can select TV, but I think the detection is actually pretty simple.
The 10-pin DIN connector on the back of the RNS is all that is needed and the contacts on that break down pretty simply into stereo audio (plus ground), red/green/blue (plus ground and sync) and two signal wires.
Those two separate signals are PAL/NTSC and Video-on. I haven't bothered measuring them, but I'd guess they are simple 5V or 12V vs 0V presence/absence, nothing cleverer.
Interestingly the TV tuner is PAL (of course) but the reversing camera comes up (brief initial display) as NTSC. I'm not sure if that initialisation display coming from the RNS or the converter box though. 
How the RNS communicates with the OEM tuner, e.g. to change channel, I have no idea, but I don't think it's down that connector, it's purely for input.
