ICE-HE-DXL Display Control Center Product Manual 042021
iCC-Net Control Overview
iCC-Net is a unique and proprietary control command protocol from Contemporary Research for sending one-way control commands to
display controllers, HDTV tuner/controllers, IPTV decoder/controllers, and HDTV tuners over new or existing video distribution
infrastructure. Separate dedicated control wiring for each component is not required. The user will be able to control the content on the
displays via channel commands as well as volume and power. The video distribution system may be CATV channels delivered over coax,
MPEG-TS IPTV streams delivered over an Ethernet network, or a combination of both.
The structure of the iCC-Net protocol command strings allows for independent control of large numbers of display controllers, HDTV
tuner/controllers, IPTV decoder/controllers, and HDTV tuners.
For RF based CATV applications, an ICE-HE-DXL display control center is required. The RF output of the ICE-HE-DXL carrying the control data
is combined with source channels to be distributed through the RF system. The control interface for the ICE-HE-DXL may be the embedded
Display Express Lite web application, a Display Express server PC, or a third-party control system. Each iCC-Net device will be assigned a
display device number. As the command strings are broadcast to all devices on the distribution network, a device will only respond when it
receives a string with a device number value that matches its configured device number. All other devices will ignore the command string.
The command string data is modulated and transmitted over a low bandwidth RF data channel. The data channel is at 74.7 MHz in the gap
between channels 4 and 5. The RF output of the ICE-HE-DXL is combined with the CATV channels at the head end prior to distribution.
When connected to an IPTV network, the ICE-HE-DXL will simultaneously send the same iCC-Net command strings as a UDP broadcast data
packets for control of compatible IPTV decoder/controllers and HDTV tuners. This allows for the creation of hybrid RF/IP systems with
seamless control.
Building an RF Based Control System
The RF based system will comprise of a control system interface to execute the commands, an ICE-HE-DXL Display Control Center, and any
combination of display controllers and tuner/controllers.
The control system requires a control system interface to execute the commands. The control system interface can be any of the following
listed below.
•
Display Express Server PC
•
Display Express Lite web page embedded in the ICE-HE-DXL
•
Third-party control processor
The ICE-HE-DXL Display Control Center is required to process the iCC-Net data from the control system and allow it to be inserted into the
CATV RF distribution system.
Display control is accomplished using display controllers and HDTV tuner/controllers. Display controllers and tuner/controllers in any
combination are utilized to receive the iCC-Net command strings and process the display specific commands for display control.
The display controllers have an RF pass-
through for connection to the display’s integrated tuner. The tuner/controller replaces the function
of a display’s integrated tuner for receiving and
decoding the CATV channels in addition to provided display control. The display controllers
or tuner/controller include the following listed below.
•
ICC1-232 display controller for RS-232 control of video displays with integrated tuner
•
ICC1-IRX display controller for IR control of video displays with integrated tuner
•
ICC1-TC tuner/controller for RS-232 control of video displays without an integrated tuner
