OFDM HD Video Transmission Motherboard

The COFDM HD Video Transmission Motherboard is a high-performance, low-power solution designed by Zixi Xinyuan for integrator customers and professional developers requiring compact, high-quality wireless video transmission. This motherboard integrates Кодовано мультиплексування з ортогональним частотним поділом (COFDM) технологія модуляції, a cutting-edge technique recognized globally for its superior performance in complex transmission environments. Its small form factor makes it ideal for integration into custom systems while ensuring excellent signal stability and reliability.

Опис товару

This motherboard supports передача відео високої чіткості and is capable of real-time streaming of HD content with resolutions up to 1920×1080p, while remaining compatible with lower resolutions such as 720p and standard definition (SD). By using the H.264 digital video compression standard, the system achieves high-quality image transmission at low bit rates, optimizing spectrum efficiency while reducing latency.

COFDM technology provides a narrow transmission bandwidth, making efficient use of radio spectrum while delivering strong resistance to interference. It also features robust anti-multipath capabilities, allowing the system to maintain signal integrity even in complex indoor or urban environments. The motherboard is capable of поза межами прямої видимості (NLOS) спосіб передавання, providing high-quality real-time video under conditions where direct visibility is obstructed by obstacles or buildings. Додатково, це підтримує high-speed motion transmission, making it suitable for aerial, землю, and vehicular applications.

Technical Core of COFDM

COFDM converts high-speed data streams via serial-to-parallel conversion, allocating data to multiple sub-channels with lower transmission rates. This design ensures excellent immunity to noise and interference, дифракція, and penetration obstacles. Key technical highlights include:

1. Strong anti-multipath interference: Minimizes signal degradation caused by reflections or echoes in urban or indoor environments.
2. High spectral efficiency: Maximizes use of available radio spectrum while maintaining stable signal quality.
3. Support for non-line-of-sight transmission: Ideal for drones, mobile vehicles, and other dynamic platforms where direct line-of-sight may not always be available.
4. Real-time high-definition transmission: Capable of maintaining HD quality video even under high-speed motion conditions.
