SM-3037B + man style remote wireless video transmission system

SM-3037B + remote wireless high-definition real-time image transmission system, the company is the production of high-definition broadcast quality real time image transmission system. Using current leading COFDM modulation technology, it has a relatively narrow bandwidth of the air (8MHz) and a strong anti-multipath interference, to overcome the conventional analog technology and image transmission modulation under multipath reflections and nuisance caused by occlusion, achieved High-speed shooting sports and non-line real time transmission of high quality images, especially suitable for use in a complex environment; video and audio encoding using MPEG-2 standard, with resolutions up to DVD resolution (720 * 576 @ PAL / 720 * 480 @ NTSC) with picture clear, bright colors, image smooth features. 2.1.1, the application can be used for police, fire, police, civil defense emergency, urban management and law enforcement, environmental monitoring, three anti-emergency, flood control, emergency power, railway rescue, maritime law enforcement, maritime surveillance patrol, customs border, port monitoring, more complex environment in real time transmission of high-quality images of moving forest fire, oil security, military reconnaissance, television, etc. for urban, maritime, mountain and so on. 2.1.2 Product features for high-speed data transfer rate is generally greater than 2M bps, meet high quality video and audio transmission. High-quality video and audio in addition to the requirements of the camera, the encoded stream, channel rate requirements are very high. COFDM technology can be selected for each subcarrier QPSK, 16QAM, 64QAM and other high-speed modulation, channel rate after synthesis generally greater than 2M bps. Therefore, it can transmit MPEG-2 4: 2: 0, 4: 2: 2 and other high-quality codecs, receiver image resolution up to 576 × 720 or 480 × 720, meet later analysis, storage and editing requirements. 2.1.3, COFDM anti-electromagnetic interference performance against frequency selective fading or narrowband interference and interference performance superior signal waveforms through joint coding each sub-carrier, has a strong anti-fading capability. In a single-carrier systems (such as digital microwave, spread spectrum microwave, etc.), a single fading or interference can cause the entire communications link failure, but in COFDM multicarrier system, only a very small part of the sub-carriers will be disturbed, and these sub channel may also employ error correction code for error correction to ensure low error rate transmission. 2.1.4, the channel utilization is high which is particularly important in the limited spectrum resources in wireless environments; when the number of sub-carriers is large, the spectral efficiency tends 2Baud / Hz. 2.1.5 Individual application form equipment for man - car, man ~ command center. Since the device power distance, can spot a wide range of mobile high-definition image transmission, line of sight can be transmitted at 60 km. 2.1.6 Product Features
