Audio LTC to VBI Conversion/Insertion
Figure 3-8 shows an example of receiving SD VITC waveform timecode on
the received 525i 5994 SDI input, and converting and outputting LTC
timecode on both an embedded output channel and the card RS-485 port.

525i 5994 SDI (w/
VITC waveform)
SDI 525i 5994
Because the RS-485 is to be used for LTC output in this
example, RS-485 Port Function is set to LTC Output.
Noting that the incoming video contains VITC waveform
timecode, Source Priority 1 is set to prioritize SDI VITC as
preferred choice. Therefore, when VITC waveform is
present, it will be considered as the source that will
eventually be outputted by the card regardless of output
format selected.
Output Status shows VITC waveform is being used as
timecode source.
Shown below is an example in which received 525i 5994 SDI video with VBI VITC waveform timecode is converted to LTC
and outputted on Emb Ch 16 and the card RS-485 port.
Audio LTC Out
on Emb Ch 16
Using the Embedded Audio Group 3/4 tab controls, LTC
is selected as the source for Emb Ch 16, thereby outputting
LTC on this channel.
(Gain and Mute controls are disabled when LTC is used as
a source)
