(continued)
• Timecode Source Status Displays Displays the current status and contents of the supported timecode
formats shown to the left.
• If a format is receiving timecode data, the current content (timecode
running count and line number) is displayed.
• If a format is not receiving timecode data, Unlocked is displayed.
• If Audio LTC is being received, the timecode running count is
displayed.
• Audio LTC Source selects audio source to be used by card audio
LTC function from Emb Ch 1 thru Ch 16.
Note: Audio LTC Source must be appropriately set for card to
receive and process audio LTC.
• Incoming ATC Packet Removal Control Enables or disables removal of existing input video ATC timecode packets
from the output. This allows removal of undesired existing timecodes from
the output, resulting in a “clean slate” where only desired timecodes are
then re-inserted into the output.
• Source Priority As described here, provides 4-level prioritization of timecode format
choices from choices shown to the left.
Source Priority 1 thru Source Priority 4 select the preferred format to be
used in descending order (i.e., Source Priority 2 selects the second-most
preferred format, and so on. See example below.)

In this example, SDI VITC 1st priority selection selects SDI VITC (received on SDI
input) over audio LTC (received on a selected card audio input channel).
The selected timecode source is embedded on the SDI video output using the
selected line number. In this example, if the SDI VITC on the SDI input becomes
unavailable, the card then uses the audio LTC data received on a selected card
audio input channel.
