摘要
为了将一种基于通道链路(Channel Link)技术的专用接口格式的相机高清视频图像进行高速无压缩光纤传输,采用了对相机信号直接高速采样、数据无损处理和编码传输的设计方法。通过自制相机信号源进行传输验证和使用实物相机进行高清视频图像实时传输实验,获得了监视器视频图像显示正常、信号时序无变化的结果,从而表明传输系统满足高清视频图像传输要求,具有高速、无视频丢帧和链路同步快的特点。
In order to transmit camera video image signal with special interface format based on Channel Link technology at high speed without compressing in the optical fiber, the design method in direct high-speed sampling of camera signal lossless data processing and coding transmission is proposed. The transmission verification of homemade camera signal source and the real-time transmission experiment of physical camera HD video indicate the normal video image display of the monitor and that there is no signal timing change. These results show that the transmission system could meet transmission requirement of the high-definition video image and has the advantages of high speed, no video frame loss and fast link synchronization.
