Contemporary Research Co. ICE-HE
Ethernet Head End Controller

OUR PART #  CRC-ICE-HE


Contemporary Research introduces a new solution for display system control and distributed media management, the ICE-HE Ethernet Head-End. Through a single Ethernet port, the ICE-HE can network thousands of iC-Net TV controllers, communicating over the same CATV cable that carries the media channels.

The industry-standard iC-Net protocol operates seamlessly over Ethernet networks, RS-232 control ports, RF coax, Cat5 wiring, and fiber optic cables. Our Display Express software or custom control systems can easily integrate all TV and video projectors across a facility or campus.
 
The ICE-HE typically distributes 1-way control over RF, operating in the gap between channels 4 and 5, without interfering with any other channel. 2-way control is available for legacy systems.

Applications:

  • Educational television systems
  • Presentation rooms
  • Auditoriums
  • Pay-per-view
  • Theme parks
  • Museums
  • Industrial video networks
