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.
