We built an underwater photon-counting wireless optical communication (WOC) system, proposed and verified a video transmission protocol for high bit error rate (BER) environment. At the transmitting terminal, each pixel of the video frame has a sequence number indicating its position, and the sequence number information and the pixel information are encapsulated into independent data frames. After the receiving terminal distinguishes between the sequence number frame and the pixel frame according to the flag bit, the pixel and the sequence number are correspondingly placed into the storage unit. The experimental results show that when the BER is more than 0.6, the contour of the video frame can still be recovered, which effectively solves the problem of pixel dislocation of video frame caused by bit error.
