Features

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 miniature high-definition wireless image receiving system LA-H6800RS is a new generation of 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),支持数字高清HDMI 输出接口及CVBS模拟音视频输出;新形设计、微型体积 、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 , The resolution is up to Full HD HD1080P, the resolution is up to (1920 * 1080 compatible with 1080I, 720P, 480P and standard definition). It supports digital high-definition HDMI output interface and CVBS analog audio and video output; new design, miniature size and easy operation .
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. Can be used in 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
Miniature design, easy to carry; easy to operate and save time; easy to realize non-line-of-sight wireless image transmission; this product has a wide range of applications; suitable for departmental institutions with high image quality requirements; it is a milestone product that replaces SD in high definition. Adopting the new digital video decoding standard of H.264 with high efficiency, the resolution reaches the full high-definition HD1080P quality, and the resolution reaches (1920 * 1080 compatible with 1080I, 720P, 480P and standard definition).
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.
