Operating Instructions
9501-DCDA Function Submenu List and Descriptions
(continued)
• SD VITC Waveform Insertion Controls For SD output, enables or disables SD VITC waveform timecode insertion
into the output video, and selects the VITC1 and VITC2 line numbers (6
thru 22) where the VITC waveform is inserted.
Note: • If only one output line is to be used, set both controls for the same
line number.
• SD VITC Waveform Insertion control only affects VITC
waveforms inserted (or copied to a new line number) by this
function. An existing VITC waveform on an unscaled SD SDI
stream is not affected by this control and is passed on an SDI
output.
• SD ATC Insertion Control For SD output, enables or disables SD ATC_VITC timecode insertion into
the output video, and selects the line number for ATC_VITC.
• Audio LTC Output Audio LTC output is routed to desired embedded and/or analog audio
outputs using the Output Audio Routing/Controls (p. 3-23). Whatever
timecode is displayed on the Output Status is converted to audio LTC and
available as an LTC audio output.
• 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.
