Said method comprises: a sending device acquiring data packets of a target data stream, and sending the data packets by means of at least two physical links with a receiving device, the sequence numbers of the data packets sent by means of the at least two physical links being the same. As data packets of a target data stream are sent by means of different physical links, instead of by means of one physical link only, when the transmission delay of the data packets in any one physical link increases due to bandwidth instability factors such as burst traffic or electromagnetic wave interference, the receiving device can combine the target video stream using data packets having a smaller delay sent by the other physical links, thereby effectively reducing the transmission delay of data.
