The Link Electronics IEC-788CG is a Closed Caption decoder for the NTSC and PAL television systems; data channels and text select are offered for user selection. The required input signal is composite or Y/C video with caption data on line 21. This model offers a copy guard decoder.
Extended Data Services is offered for such signals as "V-Chip" information.
A complementary differential input amplifier assures high common mode rejection while its phase-linear keyer cleanly inserts decoded characters into the video image.
This unit will decode Y/C video or composite according to the user's application.
NTSC or PAL
A switch or the rear panel allows the user to select decoding data within the NTSC or PAL television system.
This device is useful when a monitor without a Closed Caption decoder is used in broadcast monitoring; this device can be mounted close to the monitor because of its compact size.
A copy guard decoder is offered for the user's convenience; this operates via clamping circuitry.
