defines the number of shifted cycles for
every line; remark: 4 cycles correspond to
2 pixels; only multiple of 4 should be
programmed
defines the polarity of the sync signals
If no FID polarity transitions are detected
in the input signal, then an internal toggle
of FID polarity ensures the encoding of
some frames.
If no FID polarity transitions are detected
in the input signal, then no frames are
encoded.
