Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
the input video, and in turn re-insertion of timecode data into the output SDI.
The function can monitor the SDI video input of the card for supported
timecode formats, and then select and prioritize among SDI VITC,
SDI ATC VITC, and SDI ATC LTC timecode sources. If the preferred format
is detected, the preferred format is used by the card; if the preferred format is
not detected, the card uses other formats (where available) as desired.
The function provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
