this brightness level.
The above is based on the SMPTE
recommendation for adjusting color monitors with
SMPTE color bars. More detail may be found in
SMPTE recommendation ECR 1-1978.
Bars on Tape
The purpose for recording bars on tape is to provide
a standard color signal that has the same color and
brightness levels as the rest of the recording (your
equipment must be properly calibrated). This way, if
color or brightness needs correction on playback,
you will have a stable signal (color bars) to work
with. This may also be used as a confirmation that
your VTR is working correctly. In addition, putting
bars at the beginning of the tape gives it a more
professional look.
As a Genlock Source
The SG-7 may be used as a genlock source to feed
as many as 6 separate pieces of equipment. Each
of the six black burst outputs is able to drive a 75
Ohm input. All outputs are synchronous. These
outputs may be used to genlock VCR’s, Edit
Controllers, SEG’s, Switchers, etc. Take care with
cable lengths to assure correct timing to all
equipment.
ID Option
Both the SG-3 and SG-7 may be factory
programmed with an ID. An example would be
