"Not possible to use it with affordable crystal oscillator"
What if, after transition of H sync to black, the back porch was raised to 50%?
Seems the GE VIR locked nicely to 60hz interval reference with a cheap osc.
I must look up a schematic of a VIR board, haven't searched yet.
As for that paper from IEEE, they want $33 to read it, good luck with that.
