French dual standard TV's.

I'm thinking a Belgian 4 standard telly would have been a very complicated thing. It'd have to receive 625 lines 5 MHz negative video with FM sound, 625 lines 5 MHz positive video with AM sound with pre-emphasis, 819 lines 5 MHz positive video with AM sound with pre-emphasis (I think) & 819 lines 9/10 MHz positive video with AM sound with no pre-emphasis. It's making my head spin just thinking about it. I suppose they could have made it a bit simpler by restricting the French 819 bandwidth to 5 MHz, & of course Mr & Mrs Belgian Public would be used to a soft 819 picture..
