Many of the broadcast standards have been dictated by governments. I believe that the
625/50 standard is "CCIR?
At one time there were at least four B&W video transmission standards in Europe (we
had a tube TV with a 4-position selection knob to support them). 625/50 regular, 625/50
inverted in some way (?) used by the Dutch speaking Belgian stations, 819/50 for France,
and a different 819/50 for French speaking Belgian stations.
