easily connected to any camera type. A range of camera brackets are available to facilitate
easy mounting of the SOLO H.264 transmitter to satisfy many different camera styles.
For excellent range and coverage, the SOLO H.264 transmitter can be operated with the
Cobham Pro-RXB receiver. The Pro-RXB receiver is available with 2-way, 4-way, 6-way and
8-way diversity.

The Unique Technology - How Does It Work?
The basic video source used in Cobham broadcast products is your current stock of cameras
and lenses with a PAL or NTSC output. The SOLO product range has been designed to make
use of many common connectors, user interfaces and mounting patterns found on your
products helping you to minimise your investment in transitioning to Cobham digital.

Understanding Digital Transmission
Digital radio is a technology that carries information in a digital signal via a digital modulation
broadcasting method.
Digital transmission advantages include:
1.3.1.1
Fewer errors
Digital communications systems can tolerate large amounts of signal loss and dispersion
without impairing the ability of the receiver to distinguish a binary 1 from a binary 0.
Digital signals therefore do not get corrupted by noise as it easier to detect and correct
errors. This provides better and more predictable reception quality.
Data integrity enables Long range because repeaters take out cumulative problems in
transmission.
1.3.1.2
Better use of valuable radio spectrum
Digital signals typically use less bandwidth. It is also easier to multiplex large channel
capacities with digital. Multiple transport streams can be carried on a single frequency.
1.3.1.3
Encryption
Digital signals can be encrypted so that only the intended receiver can decode them.
1.3.1.4
Simpler to Integrate Video, Audio and Data
It is easier to combine all three signals on the same circuits since the signals are made up of
digital data.
1.3.2
Understanding MPEG
The Moving Picture Experts Group (MPEG) is a working group of experts that was formed by
ISO and IEC to set standards for audio and video compression and transmission.
