(continued)
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 the card RS-485 interface.
• 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 timecode running
count is displayed.
• If a format is not receiving timecode data, Unlocked is displayed.
• 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 RS-485 LTC (“Audio LTC”) is being received, the timecode running
count is displayed.
• 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 SD VITC Waveform
and SD ATC_VITC timecode data are present on the input video, and only
ATC_VITC is desired, using the Removal control will remove both
timecodes from the output. The ATC_VITC 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.
