Forgive my ignorance, but why was it done this way? I mean, wouldn’t it have
made sense to record at full bandwidth and then playback at full bandwidth
rather than separating it from base band?<o:p></o:p></span></p>

color:black'>The playback was where the interesting process took place.
The color was separated from the base band. Then in a heterodyne process,
the color was stabilized back to 3.58. The jitter was removed and then
the two were put back together. The result was a viewable signal but the
color was no longer locked to the video. Thus it could not be mixed with
another signal or much of anything else. This process worked without the
servo being locked to either vertical or horizontal. That was a unique
way to do it.<o:p></o:p></span></p>

Standard" position on the Colortec was used for, it was used to play back
a tape that was copied from a machine that used the RCA method to stabilize the
color.<o:p></o:p></span></p>
