IEC-788
Closed Caption Decoder
Decoder for the NTSC/PAL
system. It is capable of processing
and displaying all standard
closed caption format
transmissions. This includes
the codes specified by the FCC
Report and Order on General
Docket No. 91-1 and EIA-608
recommended practices for Captions, Text and XDS. Nine standard data
channels are supported by the IEC-788: Caption channels 1 through 4
(CC1- CC4), Text modes 1 through 4 (T1 through T4), and Extended Data
Services (XDS). The various operating modes are selectable from four
front panel switches.
A switch on the rear panel selects PAL or NTSC and a switch on the
front panel selects between 115 or 230VAC. Designed with the
professional user in mind, the IEC-788 processes composite baseband
video or S-Video. The composite video input is high impedance looping
and the S-Video is standard levels. A complementary differential input
amplifier assures high common mode rejection while its phase-linear
keyer cleanly inserts decoded characters into the video image.
Differential gain and phase are well within 0.1% and 0.1° respectively.
In addition, the IEC-788 is backed by a standard 10-year warranty.
High performance, flexibility, and economy are equally represented in
the IEC-788.

IEC-754 Video Delay DA
The IEC-754 Video Delay DA
features continuously variable
delay from 30ns to 475ns. It
offers transparent transmission,
with -3dB frequency response
to 32MHz, and -3dB to 16MHZ
with maximum delay. A
differential input is standard
and provides more than 80 dB of common mode rejection. An internal
spare 32 pin IC socket provides for additional optional delay that
increases the delay by 200, 300, 400, or 500ns. Cable equalization is
adjustable from the front panel with a calibrated control that
compensates for loss in coax cable for up to 1000’ of Belden 8281.
A delay trim on the front panel allows matching of signal propagation
delays with a range of ±5ns.

IEC-751 1x4 S-Video DA
Two gain controls on the front
panel adjust the video level to
±3dB for each the “Y” signal
and the “C” signal. The
IEC-751 Y/C Video DA has a
video bandwidth of 20 MHz,
making it a very useful device
for any S-Video application. A fuse on the front panel provides easy
replacement. Self-contained with an on board power supply, it draws
only 4 watts.

IEC-752
1x6 Video DA with 2000 feet Equalization
The most versatile video DA in
the broadcast industry, the
IEC-752 offers transparent
transmission, with a
bandwidth equal to 35MHz.
A differential amplifier on the
input is standard, and provides
more than 80 dB of
common mode rejection. UThe versatility of the IEC-752 is illustrated
by its choice of built-in features. A switch on the front panel selects
feedback clamp on and off. Gain control is ±3dB.
Cable equalization is a slider control located on the front panel that
adjust up to 1000’ of coax cable loss. When EQ switch is activated, 1000’
are added. A delay trim on the front panel allows matching of signal
propagation delays. Delay adjustment range is 6°.

IEC-787
Vertical Interval Inserter
Provides an economical
way to recover signals in the
vertical blanking interval
that may be lost during
video processing such as
video 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. The keyer employs a high-performance phase linear
circuit to provide clean insertion, completely free of artifacts.
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 you 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.
