that use this channel. The video input board can serve both standards, but the

recorder uses the range set in the From and To lines to look for the VITC
signals. If Automatic VITC detect is not used, the disk recorder expects to
find the VITC signals on the VITC Reader Line 1 (default 10) or Line 2
(default 12). If the signal is found, the
VITC Present indicator is turned on.

determines if the input is synchronized to the reference genlock signal. The
disk recorder records time-base corrected video whether or not it is also

be timed into the system, the
Auto Timed indicator is turned on. For more
information on auto timing, see “Auto Timing” on page 47.
