(continued)
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 as listed below.
• Emb Ch 1 thru Ch 16
• AES Ch 1 thru Ch 16
• Analog audio Ch 1 thru Ch 8
Note: Audio LTC Source must be appropriately set for card to
receive and process audio LTC.
• RS-485 Port LTC Control Allows RS-485 port to be used to receive LTC, or send LTC over RS-485
port as follows:
• If RS-485 LTC is to be received via the shared RS-485 port, set the
RS-485 Port Function control to LTC In.
• If RS-485 LTC is to be outputted via the shared RS-485 port, set
the RS-485 Port Function control to LTC Output. The timecode
string carried on the LTC output is that selected using the Source
Priority controls described on the next page.
• 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.
