The present invention provides a real-time video transmission method for a multipath network. The multipath network comprises at least two video stream transmission sub-paths from a transmitting terminal to a receiving terminal. The real-time video transmission method for a multipath network comprises steps of: 1) by the transmitting terminal, packing original video stream data and sequentially adding a tag into a packet header to obtain multipath transmission data, and sending the multipath transmission data packets to different ones of the video stream transmission sub-paths for transmission; and, 2) by the receiving terminal, receiving and parsing the multipath transmission data packets, and restoring the original video data stream according to the tags in the packet headers. The present invention can take full advantage of outlet and inlet bandwidths at two ends of a transmission path, and can effectively improve stability in video transmission to improve user experience.
