Contemporary Research 1 iC-Net Tips – RF Design and Installation
RF Design and Installation
The architecture of a Contemporary Research SignStream Media Express or Display Express
display control system follows the same design as a standard RF local insertion system. A
key aspect of the system is that the underlying iC-Net technology is compatible with most
existing RF systems, and control channels used for display operation will not conflict with
current TV channels or sub-channels.
Local AV, including:
o AV sources, digital cable or satellite recievers feeding analog modulators
o Off-air HDTV channels inserted as digital QAM channels
o HD sources feeding HD cable modulators
o SignStream HDTV channels
Cable Feed, using a noise filter, if needed
SignStream or Display Express control, inserted as micro control channel
Local Sources
Each local AV source feeds an RF modulator. Analog video sources, such as DVD players, or
a PC that runs standard 4:3 digital media such as digital videos or a PowerPoint information
channel, feed the AV output of the source to an analog channel modulator. CR QMOD HD
Modulators can be used to distribute HD sources as digital QAM cable channels.
There are many ways to balance the channels, depending on the design of the system.
Obviously, the output of some channels will be reduced, while others are amplified.
