Real-time video stream optimized transmission method and system based on optical communication

The invention provides a real-time video stream optimized transmission method and system based on optical communication, and relates to the field of video optical communication transmission, and the method comprises the steps: obtaining first network state data and first transmission video stream data corresponding to a past historical time period; acquiring second transmission video stream data corresponding to a target video stream to be transmitted in a future preset time window; predicting second network state data corresponding to the preset time window based on a network state prediction model; when it is detected that the second network state data satisfies a preset transmission congestion state condition, a photon coding device is used to code a photon coding video stream corresponding to the target video stream; and segmenting the photon coding video stream to obtain a plurality of photon coding modules, and transmitting each photon coding module in parallel by using a plurality of target transmissio
