Network device, system and method for video content processing

Abstract

Network device, system, method and computer readable medium for video content processing. The network device includes a memory having instructions stored thereon, and a processor configured to execute the instructions to cause the network device: to acquire a main video and a plurality of video stream segments, wherein the plurality of video stream segments are generated by preprocessing a video bullet screen by a server, and the preprocessing comprises jointly dividing the video bullet screen in time and space so that the plurality of video stream segments continuously translate in space by frame with time, the area of the screen used for playing the plurality of video stream segments is divided into continuous N picture units in the horizontal direction, each picture unit is used for playing the corresponding video stream segments, and the time from the left edge of the first frame of the corresponding video stream segment entering the picture unit from the right side of the picture unit to the left edge of the kth frame leaving the picture unit from the left side of the picture unit is T; decoding the main video by a main decoder of the network device; decoding video stream segments corresponding to odd-numbered picture units by a first sub-decoder of the network device, and decoding video stream segments corresponding to even-numbered picture units by a second sub-decoder of the network device; and playing the main video and the plurality of video stream segments.
