Central Integrated Receiver System, Six Way MaxRC COFDM Receiver
A completely new concept in central receive systems, the CIRAS-X6 receiver combines a six-way high gain antenna system with the latest diversity receiver technology, in one easy-to-install package. It offers innovative RF performance in a durable IP66-rated outdoor housing. It is particularly well suited to helicopter video downlink and electronic newsgathering operations, as well as any application where ease of operation and reliable reception are required.
The CIRAS-X6 system automatically optimizes the receive signal, virtually eliminating all human intervention. In contrast to old highly directional antennas, the CIRAS-X6 employs multiple antenna elements arranged to cover 360°of azimuth in overlapping sectors.
Operational efficiency in signal acquisition is improved by a focused approach to integration and optimization of the antenna design, use of adaptive digital signal processing (ADSP) and maximal ratio combining (MRC) techniques. Formerly these three areas have been treated and controlled independently. By combining and optimizing these areas, IMT provides a new class of fully autonomous Central Receiving Systems that provide significant value and efficiency to the industry.
The IMT CIRAS-X6 features a compact, lightweight rugged IP rated chassis making it equally suited to rooftop, tower, vehicle, or portable applications. The CIRAS-X6 uses Ethernet for control and power as well as providing an MPEG Video Over IP transport Stream, eliminating the need for expensive RF and control cables. The CIRAS-X6 sends the MPEG Transport Stream by Ethernet cable to a local decoder, video management system and/or a network distribution center. Smaller, less expensive cables minimize installation costs. Interference from strong signals from nearby transmitters getting into RF cables is eliminated. The small radome and light weight make it the perfect receiver to use with pneumatic masts on emergency vehicles.
All CIRAS-X6 functions are monitored and controlled through an intuitive Web GUI. No standalone control system is required. Select the channel, and the CIRAS-X6 automatically detects the bandwidth, modulation, spectrum, and encryption keys. design, use of adaptive digital signal processing (ADSP) and maximal ratio combining (MRC) techniques.
