Link electronics Two Field Closed Caption Decoder IEC-788 Specification Sheet

LINK ELECTRONICS, INC.

TWO FIELD CLOSED CAPTION DECODER
PAL & NTSC, COMPOSITE PLUS Y/C

MODEL IEC-788

MADE IN THE USA

CLOSED CAPTION SERIES

FEATURES

 Field 1 & Field 2
 Captions
 Text
 XDS
 EIA-608 Extended Character Set

The IEC-788 is a high performance Closed Cap­tion 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 (CC1­CC4), Text modes 1 through 4 (T1 through T4),
and Extended Data Services (XDS). The various
operating modes are selectable from four front
panel switches.

Packaged in LINK's compact 700 Series chassis,
the IEC-788 is both rugged and reliable. If desired,
it may be rack mounted along side two other 700
Series units of any mix.

 PAL/NTSC
 S-Video Input & Output
 Baseband Video Input & Output
 Differential Input
 Rack Mountable (Optional Tray)

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
Closed Caption Decoder.
