[Tig] sync gen question.

Theoretically you could do without a tri-level sync generator by running the
Spirit on internal sync. This is very limiting however as you cannot
reliably down-convert. The 2K only locks to incoming video, so it won't be a
problem, however to get the 2KTLC (or external TLC2) to operate correctly
you will need at the least a 6Hz generator locked to your NTSC reference.

The easiest way to do this is with an Evertz 7000 system tri-level card
which gives tri-level 48hz as well as bi-level 6hz and can be gen-locked to
an external 525 reference.

The HDCAM will lock to the system tri-level, or you can leave the reference
in AUTO mode and it will also lock to incoming video.
