In recent years, need of transmitting high quality video signal for industrial Internet of Things (IoT) is increased for monitoring and manufacturing process automation. In mid sea oil rigs, during oil exploration autonomous systems are used widely which requires better video transmission through Underwater Wireless Optical Connection (UWOC). The underwater optical links are affected due to various water types, distinctive water profundities, various seasons, diverse weakening attributes the signal transmitted may endure different issue like absorption, scattering, reduced SNR, expanded BER, link misalignment issues, which will prompt low quality video. In this paper, the UWOC link characteristics such as BER, link mis alignment, video quality, pertaining to video transmission for various modulation techniques are analysed. The simulation results state that, UWOC communication link equipped with better error correction scheme results in better video quality.

近年来，用于监视和制造过程自动化的工业物联网（IoT）传输高质量视频信号的需求不断增长。在中海石油钻井平台中，石油勘探期间广泛使用了自治系统，这需要通过水下无线光学连接（UWOC）进行更好的视频传输。水下光链路受以下因素影响：各种水类型，不同的水深，不同的季节，多样的减弱属性，所传输的信号可能会遇到不同的问题，例如吸收，散射，SNR降低，BER扩展，链路未对准问题，这将导致视频质量降低。本文分析了与各种调制技术的视频传输有关的UWOC链路特性，例如BER，链路失准，视频质量。
