Noting that the incoming video contains audio LTC on Emb
Ch 9, Audio LTC Source is set to receive audio LTC via
Emb Ch 9.
Audio LTC Status verifies that LTC is being received on
selected audio source.
(RS-485 Port Function setting is immaterial to example
here)
Source Priority 1 is set to prioritize Audio LTC as preferred
choice. Therefore, when audio LTC is present, it will be
considered as the source that will eventually be outputted on
the video stream.
Output Status shows audio LTC is being used as timecode
source.
Shown below is an example in which received 720p 5994 SDI video without VBI timecode is to receive audio LTC. The audio
LTC is converted to VBI ATC_VITC timecode and inserted into the SDI video as shown below.
