Embodiment Construction
[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0048] The main solution of the embodiment of the present invention is: send a network data packet to the receiving end, the network data packet includes encoded video frame data and FEC redundant data, and the FEC redundant data is determined to have corresponding FEC redundant data according to the network packet loss rate Level; receive the feedback data sent by the receiving end; when the feedback data is packet loss feedback data, according to the current packet loss model of the packet loss feedback data, reselect the corresponding level from the preset multiple sets of redundancy levels of FEC redundancy data In addition, when the feedback data is decoding error feedback data, according to the current decoding error model, the independently decodable frame corresponding to the decoding error frame is obtained an...
