(continued)
Audio LTC controls described below only appear on cards with +LTC licensed optional feature. This feature
allows audio LTC from an embedded audio channel to be used as a timecode source, with conversion to a selected SMPTE 12M
format on the output video.
• Timecode Source Status Displays Displays the current status and contents of the received timecode formats
shown to the left.
• If a format is receiving timecode data, the current content (timecode
running count) is displayed.
• If a format is not receiving timecode data, Not Present is displayed.
• Audio LTC Source and Mute Controls
(+LTC option only)
LTC Input control selects input embedded audio channel when audio LTC
is to be used as a source.
Mute LTC Audio control allows timecode using LTC audio sources to
freeze as follows:
• When set to Enabled and input timecode is lost, timecode insertion is
disabled.
• When set to Disabled and input timecode is lost, timecode output
reverts to free-run.
Note: If muting upon loss of a particular input format is desired, set all
Source Priority 1 thru 4 to that particular input format. If this is not done,
the card failover timecode selection may substitute another format choice
for the format not being received.
• 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. (For example, if both SDI ATC_VITC and
ATC_LTC are present on the input video, and only ATC_LTC is desired,
using the Removal control will remove both timecodes from the output.
The ATC_LTC timecode by itself can then be re-inserted on the output
using the other controls discussed here.)
Note: When the Scaler is enabled, ATC packets are automatically
removed. The Timecode function must be used to re-insert the
timecode data into the output video.
• Timecode Master Insertion Control
Turns on (when checked) or turns off Timecode insertion onto the output
video.
Note: This control must be enabled for any timecode re-insertion
regardless of desired timecode output format.
