FEATURES

VBI Insertion
Field 1 & Field 2 Process
Line 10 thru 21
Recover Lost Captions
The LINK model IEC-787 is a video inserter that
provides an economical way to recover signals in
the vertical blanking interval that may be lost
during video processing
compression or overlay and comb filtering. This
would include Closed Caption data on line 21,
Ghost Cancellation Reference signal on line 19
and other signals in the vertical interval.
Using front panel switches, any of lines 10 through
21 may be selected for insertion by the IEC-787.
Odd and even fields are handled separately. The
keyer employs the same high performance phase-
linear circuit used by LINK Closed Caption
equipment to provide clean insertion, completely
free of artifacts. Overall video handling is
outstanding as well.

Differential input configuration is standard on both
video inputs, but single ended configuration can be
selected by an internal jumper.
A switchable Monitor output allows the user to
view either of the video inputs ahead of the keyer.
For system timing, a front panel calibrate switch
will cause the unit to alternate between inputs at a
field rate. If no input is connected to the VBI
Source Input BNC, the IEC-787 may be used to
simply pass or delete selected lines in the VBI of
the program video.
Packaged in LlNK's attractive and rugged 700
series chassis, and covered by a ten-year
warranty, the IEC-787 will provide years of reliable
service.
