Page 7: Introduction
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...
Page 8: Configuration Examples
Figure 1: Connections and data flow 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.

Page 15: Mounting Procedure For A Single Receiver
• The rack should be a minimum of two inches (5.1 cm) away from the receiver, and the back of the rack should be a minimum of four inches (10.2 cm) from the receiver’s back panel. • Since there is no power button (on/off switch) on the receiver, ensure that you have access to the rear of the rack or leave a sufficient wire management loop to pull the unit out from the front of the rack.
Page 16: Mounting Procedure For Two Receivers
Mounting procedure for two receivers To mount two receivers side by side, you will require 2RU (3.5 inches, 89 mm) of vertical rack space and a Real Freedom Dual Receiver Rack Mount Kit (BRK-0006-00). Figure 7: Joining two receivers for rack mounting. 1 Bracket Fixing 2U, 2 Joining Blocks, 3 Bracket Fixing 2U, 4 Block Joining Rear.
Page 17: Connect Real Freedom Components
Since systems are typically installed in shared circuits, be aware of how many units are plugged into the source and the total current draw. WARNING: Connect the product only to a power source with the specified voltage rating. AC SUPPLY When powering from an AC supply, you must connect the receiver to the mains supply using the IEC mains cable provided.
Page 18: Connect Downconverters To The Receiver
Alternatively, use an active UHF splitter to connect six Real Freedom Receivers to a single fiber base unit. CAUTION: To prevent damage, it is recommended that you only use BSI supplied cables and accessories with the receiver. Connect downconverters to the receiver Up to eight downconverters can be directly connected to the receiver using coaxial cables.

Page 20: Receiver Configuration
Receiver configuration Once you have connected all the Real Freedom components and made the connections to the Real Freedom Receiver, you must enter some basic configuration information. If the camera is live, you should see a preview of the video on the receiver’s screen, which can help during the configuration process. Overview After powering on the Real Freedom Receiver, enter the configuration menu by pressing the left arrow button from the front panel constellation navigation controls.
Page 21: Network Configuration Notes
NOTE: Select a BSI camera type to remotely-control the transmitter from the receiver. When under ‘BSI control’, the receiver is the ‘master’ and the ‘transmitter’ the slave. If the system is not under ‘BSI control’, the transmitter parameters can be set independently to those on the receiver.
Page 22 BSI Iris Only applies to a BSI camera without linear iris control. Select ‘On’ if you are using a BSI Point of View (POV) camera that does not have a linear iris. BSI POV Timeout Only applies to a BSI POV camera.

Defines the modulation scheme. The default value is ‘DVB-T’, a European Modulation Scheme digital video broadcasting standard. In ‘BSI control’ mode, the selected scheme syncs with the transmitter. Real Freedom | Receiver Product Manual 23 of 51...
Page 24: Remote Transmitter Control Settings
In ‘BSI control’ mode, the selected value updates the camera back transmitter. If the bandwidth is not correct, the system will still work if under ‘BSI control’, but if not, you will need to match the value to the transmit parameters.
Page 25: Fiber Remote And Splitter Settings
Setting Description Symbols Lower order modulation formats like QPSK do not transmit data as fast as the higher modulation formats such as 64-QAM, but they can be received when signal strengths are lower. Code Rate Match the code rate to the requirements of the broadcast network. The higher the level of error correction that is applied, the greater the level of supporting error correction data that needs to be transmitted, which reduces the data rate of the transmission.
Page 26: Video Settings
Sets the required sync offset to delay the video feed. The required offset depends on the transmitter, so you must check and select the type of BSI transmitter that you are using. If set incorrectly, the image may freeze or result in picture judder.

‘BSI control’. This value corresponds to a value that can also be set manually on the transmitter. If the transmitter is configured as ‘BSI control’, then this overrides anything that you may set on the transmitter. Audio Output Defines which audio channels will be output onto the two rear panel audio XLR connectors.
