ICW-STA

Stereo TV Tuner

2-Way Cat5 Control

The Contemporary Research ICW-STA is a versatile iCW-Net controlled TV tuner featuring optional on-screen text,
stereo audio, 125 channel access, front-panel operation and feedback, and intelligent control. Fully programmable,
the unit can restore all settings on power-up from non-volatile memory. the unit can restore all settings on power-up
from non-volatile memory. A list of channels can be stored in memory, used to provide convenient channel up/down
operation and restrict direct access to other channels.

An optional onboard character generator provides on-screen text for channel names, interactive menus, and system
feedback. Switchable inputs for NTSC video and stereo audio are included for display of PC graphics, a character
generator information channel, camera or other A/V sources.

High-speed 2-way control and feedback is carried over a wired twisted-pair network using Category 5 or Category 3
wiring and connectors. Compatible with the Contemporary Research ABC Media Retrieval System and iC
Commander software, the ICW-VDC can be networked with up to 4000 TV and Video Display controllers. For
custom systems applications, all ICW-VDC units and other CR devices can be accessed from a single RS-232 port
on an ICC-HE or ICW-HE Head-End Network Controller.

Applications include TV channel origination for educational television systems, theme parks, museums, government
facilities, arenas, convention centers, airports and corporate video networks.
