Google suggests that you find a copy of ITU 601, It sounds as if ITU
601 wants you to lock your pixel-level sampling clock to the line scan clock - presumably with some form of phase-locked loop. You can probably get away with using a voltage-controlled crystal oscillator as the adjustable clock source.

Back in the long ago times it would have been a time of day clock locked to the power line frequency - probably has some other meaning today

Probably is that today as well. Some 20-odd years ago I worked on such a system, that was locked to the mains frequency so as to fire thyristors at the desired phase angle, even in Sudan.
