Timecode
Proc
525i 5994 SDI (w/
VITC waveform)
SDI 525i 5994
Noting that program material VITC waveform timecode is only
to be used, Source Priority 1 is set to prioritize SDI VITC as
the only 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 on SDI A is converted
to Audio/RS-485 LTC and outputted on SDI A Emb Ch 7 and an RS-485 port.
Audio LTC Out
on SDI A
Emb Ch 7
Using the SDI Crosspoint tab controls, SDI A LTC encoder output LTCA is selected as the source for SDI A Emb Ch 7, thereby
outputting LTC on this channel. (If this LTC output is intended for any other audio channel, either AES, MADI, or another video
path embedded channel, it can be applied by selecting LTCA also for other channels as desired.)
RS-485 LTC
Out on COM 1
Because COM 1 is to be used for the RS-485 LTC output in this example,
COM 1 is set to Out - LTCA Encoder on the COM Routing tab.
