[QuadList] RCA Color Tape

[Chill315 at aol.com]

RCA used direct color for the recording.  Nothing was done to the  signal.  
It was recorded at full bandwidth to the tape.
 
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.
 
As a side point, if you ever wondered what the "Non 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.
