Noting that the incoming video contains ATC_LTC
and ATC_VITC timecode data (as shown in the status
display), in this example the Source Priority
drop-down lists is set to include ATC_VITC timecode
data as the preferred choice. This extracts the
selected timecode data from the incoming video.
Since ATC_VITC is the preferred choice and is
available, the received ATC _VITC timecode data is
selected and re-formatted as SDI VITC timecode
data.
In this example, With SD VITC Waveform Insertion
set to Enabled, the SD VITC timecode data is placed
on the output SDI video.
In the example here, the line numbers are set to the
default values.
