Rob Brigham:
Does the CRT display its data from the sensor, or does it read back what has been written to the tape/media?
It has to be data from the sensor, or else the tape player must have separate playback heads after the record heads. I don't think that is the case in either Betacam SP or DVCAM. I've never seen a switch for it at least, like reel-to-reel audio players have. In Digital Betacam the order is the other way around, playback first and record after, to be able to process the playback signal and record the processed version back to the same frame.
However, studio cameras have a switch so the operator can see either his/her own camera or which image the producer has chosen in the mixer at the moment. But this is after mix only, it's still not after tape.
