Audio LTC and RS-485 LTC controls described below only appear on cards with +LTC licensed optional
feature. This feature allows bidirectional conversion between VBI-based timecode and LTC timecode on audio and RS-485
interfaces.
• 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. (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.
• 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.)
