NOTE: When transmitting S-video, luminance uses the green video pathway, and
chrominance uses the red video pathway. When transmitting composite video, the
signal is carried on the blue video pathway.
NOTE: Use Crescat-QM, or good quality CAT5E / CAT6 cable to make QM
connections. The cumulative skew over the entire length must be less than 15 ns.
Refer to “QuickMedia Wiring” on page 16 for cable specifications.
NOTE: When using Crescat-QM wiring, four additional wires are included for
making Cresnet connections. Refer to “QuickMedia Wiring” on page 16 for cable
