| 摘 要： | 为了实现设备之间快速、安全的通信接入,将以太网视频传输与室内可见光通信原理相结合,实现了单向可见光视频传输系统。提出了对视频数据进行4B5B和NRZI编码,利用UDP协议进行传输,并由CDR(Clock and Data Recovery)芯片恢复同步时钟数据。最终,设计了发送电路和接收电路,并对时钟恢复和系统整体性能进行了测试。测试结果表明,基于4B5B编码的可见光视频传输系统可以实现1M距离以内的以太网视频传输。

| Abstract: | In order to realize a rapid and safe access mode between equipments, the Ethernet video transmission and indoor visi-ble light communication principle are combined to achieve a one-way visible light video transmission system. This paper puts for-ward a method using 4B5B, NRZI and UDP protocol, then uses the CDR （Clock and Data Recovery） chip to recovery synchronous clock and data. Finally, it designs a transmitting circuit and receiving circuit, and tests the performance of CDR and overall system. The results demonstrate that the system based on 4B5B can realize video transmission at 1M distance. |
