是公司生产的新一代广播级高清晰度图像实时接收系统。 The handheld high-definition wireless image receiving system LA-H6800RH is a new generation broadcast-level high-resolution image real-time receiving system produced by the company. 高效压缩 H.264 新数字视频解码标准 ,清晰度达到全高清HD1080P画质,分辨率达到(1920*1080兼容1080I、720P、480P及标清),内置9寸高清全视角显示屏,支持CVBS 输出接口;内 置高容量电池供电系统,操作简便 Adopting the current leading COFDM demodulation technology, relatively narrow-band air frequency occupation (2 / 2.5 / 4 / 8MHz) and strong anti-multipath interference ability, combined with foreign advanced diversity receiving technology, overcomes analog technology and conventional modulation technology Difficulties caused by multi-path reflection and occlusion in image transmission, to achieve high-speed motion shooting and receive high-quality images in real-time under non-line-of-sight (non-line-of-sight) conditions; using the new digital video decoding standard H.264 with high efficiency compression , Clarity reaches Full HD HD1080P quality, resolution (1920 * 1080 compatible with 1080I, 720P, 480P and SD), built-in 9-inch high-definition full-angle display, supports CVBS output interface; built-in high-capacity battery-powered system, easy to operate .

Application range

It is mainly used in broadcasting and broadcasting, broadcasting and broadcasting: broadcasting, sports broadcasting, social ⎝⎛叫我棋牌⎞⎠, air live, studio, mountaineering and other aspects. It can be applied to public security, fire protection, traffic police, civil air defense emergency, urban management law enforcement, environmental protection monitoring, three defense emergency, water conservancy flood prevention, power rescue, railway rescue, maritime law enforcement, sea surveillance inspection, customs border control, terminal monitoring, forest fire prevention, oil field anti-theft Military reconnaissance, TV broadcasting, etc .; suitable for real-time mobile transmission of high-quality images in a variety of complex environments such as urban areas, seas, and mountains.

Product Features

    Handheld integration, easy to carry; simple operation, save time; easy to realize non-line-of-sight wireless image transmission; this product has a wide range of applications; suitable for departments and institutions with high image quality requirements, is a landmark product that replaces SD with high definition . It adopts the new digital video decoding standard of H.264 with high efficiency, and the resolution reaches the full high-definition HD1080P quality, and the resolution reaches (1920 * 1080 compatible with 1080I, 720P, 480P and SD) .                   

COFDM anti-electromagnetic interference performance

It has excellent performance against frequency selective fading or narrow-band interference and interference between signal waveforms. It has strong anti-fading ability through the joint coding of each subcarrier. In a single carrier system (such as digital microwave, spread spectrum microwave, etc.), a single fading or interference can cause the entire communication link to fail, but in a multi-carrier COFDM system, only a small part of the subcarriers will be interfered with, and these subcarriers The channel can also use error correction codes for error correction to ensure a low bit error rate for transmission.

COFDM anti-multipath fading performance

It can effectively combat the interference between signal waveforms, and is suitable for high-speed data transmission in multipath environments and fading channels. When frequency selective fading occurs in the channel due to multipath transmission, only the subcarriers that fall in the band depression and the information they carry are affected, and the other subcarriers are not damaged, so the overall bit error rate performance of the system is better many.

Application form of receiving equipment

It is suitable for field-to-vehicle reception, field-to-room reception, aerial image transmission, and wireless image transmission on drones.
