There are a number of CCIR 625/50 standards, as well as other CCIR/ITU-R

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.
