(continued)
• HD ATC_VITC Insertion Control
For HD output, enables or disables ATC_VITC timecode insertion into the
output video, and selects the line number for ATC_VITC1 and
ATC_VITC2.
• ATC_VITC Legacy Support Control
When enabled, accommodates equipment requiring ATC_VITC packet in
both fields as a “field 1” packet (non-toggling).
Note: Non-toggling VITC1 and VITC2 packets do not conform to
SMPTE 12M-2-2008 preferences. As such, ATC_VITC Legacy
Support should be enabled only if required by downstream
equipment.
• Free Run Timecode Controls
Allows an initial (starting) count to be applied to output video timecode
when Free Run insertion is enabled.
Note: • Initialization can only be applied when card is outputting Free Run
timecode (as shown by Output Status displaying “Free Run”).
• If failover to Free Run occurs due to loss of external timecode(s),
the Free Run count assumes its initial count from the last valid
externally supplied count.
