Note: The timecode function is tied to and considers timecode sources only
received on SDI IN A.
(See Figure 1-2.) This function provides for extraction of timecode data from
input video source, and in turn allow individual timecode strings to be
embedded and/or burned into the output video. The function can monitor any
of the video inputs of the card for supported timecode formats such as
ATC_LTC or ATC_VITC for down-conversions to HD, and ATC_VITC or
VITC waveform (with selectable odd/even field line number control) for SD
SDI or CVBS inputs. Waveform VITC timecode can also be extracted from a
reference input and used as the output timecode value. 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. An
internally-generated free-run timecode can be also be embedded on output
video if desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
receive, send and translate between audio LTC timecode formats and the VBI
formats described above.
