                                        REPORTER Mobile wireless COFDM system

 

    Receiver, modulator and power supply unit

 The Reporter Mobile wireless COFDM system is intended for digital video/audio transmission
in a frequency range of 2GHz from a TV van to central TV studio.The system provides reliable
transmission for up to 25km line-of-sight. Also it can transmit to at least several kilometers non-line-of-sight (the distance depends of an environment) and provides reporting on the move. The system is best suited for news, music festivals, sports broadcasting and can be mounted in ground or airborne vehicles. In conjunction with the VIDEOLINK wireless system it provides real-time reporting without wasting time on equipment deployment (mounting antennas, unrolling cables and so on).

 

                         1. The VIDEOLINK Wireless Camera COFDM System

                            • VIDEOLINK transmitter;
                            • diversity receiver (ASI, CVBS, Stereo Audio outputs);
                            • active antennas (2pcs); 

                         2. The REPORTER Mobile system

                            • TV van equipment
                            • COFDM modulator of 2GHz frequency range (ASI input) housed in Rack 2U;
                            • Power amplifier of 2GHz freThe system includes:quency range (available                                                              power output of 1W or 5W) packaged in Rack 2U or hermetic housing;                                                                 Power supply unit;
                            • Transmitting omni-directional antenna providing gain of 8 dB;
                            • Transmitting directional antenna providing gain of 24 dB.

                         3. TV studio equipment

                            • Diversity receiver (ASI, SDI, CVBS, Stereo outputs);   
                            • Downconverter transforming the signal from 2GHz frequency range to a receiver                                                  frequency range (2pcs);
                            • receiving omni-directional antenna providing gain of 8 dB.


                                Brief specification:

                            • Fast start-up time 10 s
                            • Modulation СOFDM (DVBT 2K) 
                            • Guard interval 1/4
                            • Modulation 16-QAM 
                            • Code rate 1/2 
                            • RF output frequency 2 GHz
                            • Channel bandwidth 8 MHz
                            • Bit rate 10 Mb/s
                            • Encoding 4:2:0 MPEG2
                            • compliant to ISO IEC13818
                            • DC supply voltage 12-24 VDC

 

                 There can be offered the following system solutions under different signal                                                                                 transmission conditions
