As we progress in this discussion, we are getting more into the basics
of professional video reproduction which may be off topic for our
forum, but I wanted to add that about one to two minutes of these color
bars and audio tones are generally put on the head of a professional
video tape when it's recorded to enable an engineer to be able to play
it back at a later time with the proper audio and video settings. So,
both the video tape and the monitor used to view it must be properly
set up for things to be up to SMPTE standards.|
Fortunately, as someone has already mentioned, most home equipment playback equipment does a pretty good job of this, automatically, so such "standards" are truly academic to the average viewer. Generally, it's the picture (or TV) monitor settings at home that distort the original intent and the balances of audio and video of the recording when it was mastered.
