对输出端视频信号的处理是光端机设计的关键。文章首先简要介绍了四路数字视频光端机的系统架构和工作原理,然后详细描述了基于CPLD的四路数字视频光端机的设计过程,最后对实验结果作了分析。相比传统的光端机,本系统在硬件设计上对输出端视频信号处理方面作了改进,选择具有DirectDrive技术的MAX9530对视频信号进行处理,很好地解决了视频信号的干扰问题,同时提高了视频图像的质量。
The output of the video signal processing is the key to the optical design. The article first briefly introduces the system architecture and working principle of the four-channel digital video optical transceiver, and then describes the design process of the four-channel digital video optical transceiver based on CPLD in detail. Finally, the experimental results are analyzed. Compared with the traditional optical transceiver, this system has improved the output video signal processing in the hardware design. The MAX9530 with DirectDrive technology is used to process the video signal, which solves the problem of video signal interference and improves the video The quality of the image.
