ATC_VITC1 = Line 9 (default SMPTE 12M-2)
ATC_VITC2 = Line 8 (571) (default SMPTE 12M-2)
ATC_LTC = Line 10 (default SMPTE 12M-2)
Noting that analog VITC contains the timecode
source (as shown in the status display), the Source
Priority drop-down lists can be set to include Analog
VITC timecode data as a preferred choice. This
extracts the analog VITC waveform timecode data
from the analog VITC input.
In this example, since it is desired to provide both SDI
ATC_VITC and ATC_LTC timecode data in the SDI
output video, both HD ATC VITC Insertion and
HD ATC LTC Insertion can be set to Enabled.
In the example here, the line numbers are set to the
default SMPTE 12M-2-2008 recommended values.

Shown below is an example in which received analog VITC waveform is extracted and applied to the 720p 5994 (2997 frame
rate) stream as both ATC_VITC and ATC_LTC packets. Each Timecode control is fully described on the pages that follow.
