Introduction
The Real Freedom wireless camera system is designed to provide an end-to-end wireless video and audio
link for professional television broadcast applications. The system comprises a camera back transmitter, a
receiver unit and up to eight downconverters (receive antennas) with integrated camera control data.
Overview
The Real Freedom Receiver, which forms the heart of the system, is a next generation Integrated Receiver
Decoder (IRD) comprising up to eight UHF inputs, DVB-T and T2 demodulators, and both MPEG-2 and
H.264 video decoders. The UHF inputs can be connected to a variety of Real Freedom Downconverters,
providing wireless receive in a selection of frequency bands. The internal video decoders provide ultra low
latency performance and, when used in conjunction with a Real Freedom Transmitter, can achieve one
frame end to end delay or two frames when using receiver frame sync.
Eight RF inputs allow for diversity reception from four independent locations and decoding of a single video
stream. The receiver also supports demodulation of dual pedestal RF signals, either as a single or dual video
stream. In dual stream mode, you can select which stream is presented to the decoder, while the other
stream can be passed to the ASI output for decoding elsewhere.
Designed with the hire customer in mind, the receiver features a simple interface with easy adjustment of the
main system parameters. A 5-inch color panel displays the video and shows a Connection Map, audio peak
meters and other key parameters when required. An integrated camera control feature allows you to
configure the data transmitters and fine-tune the image remotely without using any additional cables.
Unique to the industry, the receiver also includes full camera control capability out of the box. A third-party
camera Operator Control Panel/Remote Control Panel (OCP/RCP) can be connected to the receiver over
Ethernet. Connecting a Real Freedom Data Transmitter to one of the system’s downconverters provides a
UHF back channel to the mobile camera and provides full remote control of the camera transmitter and the
camera paint functions.
System architecture
The receiver’s main function is to demodulate and decode the video signal received from the camera back
transmitter. The 5-inch color panel in the front of the receiver displays the decoded video providing a live
preview and facilitating further control of configuration parameters, as required. Multiple receivers can be
networked together enabling them to share a single data transmitter and single data channel for up to six
networked RCPs.
The following schematic shows the connections between the various components in the system, the flow of
control data from the control panel to the camera via the receiver, and the flow of video and audio from the
camera to the receiver.

Configuration examples
Example 1
This example shows a simple configuration with eight downconverters connected to a single receiver.
Figure 2: The data transmitter receives camera control data from an RCP via the Real Freedom Receiver and transmits
a GMSK-modulated narrow band UHF signal of between 430 MHz and 490 MHz. For maximum flexibility, plug the data
transmitter into any downconverter.

Example 2
This example shows networked camera control of six cameras over one UHF frequency.
Figure 3: Networked camera control over one UHF frequency.
Example 3
This example shows multiple RF cameras incorporating camera control deployed from a single remote site
utilizing a single SMPTE hybrid fiber cable. The cable simultaneously powers remote Real Freedom
Downconverters and Data Transmitters.
Figure 4: Networked multi camera reception with fiber antenna extender and active splitter. Up to six Real Freedom
Receivers can be simultaneously supported by a single fiber base unit when utilized with the optional Real Freedom
Active UHF Splitter.
