COFDM high-definition image transmission mainboard

product description:The COFDM high-definition image transmission motherboard is a low-power model developed by Zixi Xinyuan.,Small size motherboard,For Integrator Customers,Using COFDM modulation technology,Has a narrow transmission band、Strong anti-multipath interference ability and anti-multipath fading ability,Able to achieve non-line-of-sight (NLOS),Real-time transmission of high-quality images under high-speed motion。 The system adopts H.264 digital video coding standard,Output HD1080P picture quality,Resolution up to 1920*1080 (downward compatible with 720P and SD。

Product Details:

1、Coded Orthogonal Frequency Division Multiplexing;It is the most advanced and potential modulation technology in the world。

2、Practical value;Support for applications that break through the limit of sight distance,It is a technology that makes full use of radio spectrum resources。

3、The technical core of COFDM;Can have good immunity to noise and interference,Diffraction and penetration obstructions。Has a narrow transmission band、Strong anti-multipath interference ability and anti-multipath fading ability,Able to achieve non-line-of-sight (NLOS),Real-time transmission of high-quality images under high-speed motion。

4、Fundamental;Convert high-speed data streams through serial-to-parallel conversion,Allocated to several sub-channels with lower transmission rates for transmission。

Product advantages:

1、high flexibility,easy to expand。

2、Long transmission distance。

3、low latency,real-time transmission。

4、microwave transmission,No need to rely on the network。

5、Clear picture quality up to HD 1080p effect

5、Small size of the machine,Other standards can be customized。

6、Strong anti-interference ability and non-line-of-sight diffraction ability
