Noting that RS-485 LTC is be be received on COM 1, LTC
Input is set to receive audio LTC via COM 1.
Also, COM 1 is selected to be the source the the LTC input.
Input LTC Status verifies that LTC is being received on
selected routing source.
Source Priority 1 is set to prioritize Input LTC as the preferred
choice. Therefore, when RS-485 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 720p 5994 SDI video without SMPTE 12M VANC timecode (on card path SDI A) is to receive
RS-485 LTC. The RS-485 LTC is converted to VBI ATC_VITC timecode and inserted into the SDI video as shown below.
RS-485 LTC on
COM 1
Received audio LTC is converted to ATC_VITC and inserted
into the SDI output video as shown here using
HD ATC VITC Insertion set to Enabled (in this example, the
SMPTE recommended line number are used)
