The PRORX from Cobham Tactical Communications and Surveillance is a feature-rich multi-way diversity COFDM receiver, featuring Cobham technology at its core. Supporting interoperation with other manufacturers’ DVB-T systems and able to receive the Cobham transmitter family, the PRORX is supplied in a 1/2 19” 2U high rack receiver chassis, where two units can be mounted together to occupy a 19” slot.

It is available with 2-way, 4-way, 6-way and 8-way maximum ratio combining RF inputs, ensuring video is recovered free from the distortions typically associated with fading and multipath. Designed to work with external Cobham down-converters, the receiver will provide phantom power on its inputs for this purpose.

The PRORX incorporates a fully featured SD MPEG2 decoder, with composite and SDI video outputs as well as a Genlock video input.

The PRORX can be controlled through its OLED front panel display, as well as on its RS232 or IP Ethernet browser control interfaces.

For customers wanting to distribute received video to remote locations, the PRORX is supplied with ASI and IP streaming outputs.

A comprehensive On-Screen Graphical display is available for monitoring and diagnostics, which can be enabled or disabled separately on the composite and SDI outputs.

The PRORX can be upgraded with a second video decoder output (PRORX-DEC2). The advantages and limitations of this are described in a separate datasheet.

TX Features:

• Low delay H.264 SD & HD encoding
• HD-SDI/SDI with embedded audio input
• Composite video input
• HDMI input with embedded audio input
• ASI input and output
• DVB-T 6/7/8MHz and optional narrowband modulation
• Low power consumption 10W
• Ultra lightweight 400g

The SOLO H.264 Transmitter from Cobham is a rugged, Standard or High Definition digital video transmitter, ideal for motorsport, airborne, sports, news links and law enforcement surveillance applications.

The H.264 Transmitter can operate in a variety of transmission bandwidths allowing the user to trade off image quality against range to suit all types of applications. Excellent range, performance and spectral efficiency are offered when operating in the optional narrow bandwidth mode, which combined with the ultra efficient H.264 encoding allows true broadcast quality pictures to be transmitted in only 2.5MHz bandwidth. This enables users to maximise usage of limited RF spectrum as 2 or 3 cameras can occupy the bandwidth previously required by a single MPEG2 system. All modes of DVB-T modulation are also supported.

The increased compression and efficiency of the MPEG4 H.264 encoder offers users additional range with the added benefit of small size, low latency and low power consumption. In particular, HD transmission is possible using 40% lower bit-rates than conventional MPEG2 systems, enabling true HD transmission in a single 8MHz DVB-T channel whilst using robust modulation settings. Able to transmit images in a non-line of sight environment up to 1km depending on mode and frequency, the
transmitter can achieve even further range with an optional clip-on booster PA.

Greater security of the transmission can be ensured using the optional internal AES128/256. The SOLO H.264 transmitter features mounting holes for bespoke applications and can be 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 (see separate datasheet). The Pro-RXB receiver is available with 2-way, 4-way, 6-way and 8-way diversity.
