| Zusammenfassung: | The embodiment of the invention provides a redundant code rate determination method, device and equipment based on hybrid retransmission. According to the technical scheme provided by the embodiment of the invention, the redundancy pre-estimation code rate of the forward error correction strategy is determined according to the video source stream code rate and the current packet loss rate, and when the sum of the redundancy pre-estimation code rate, the video source stream code rate and the retransmission code rate of the automatic retransmission strategy exceeds the estimation bandwidth, the forward error correction strategy is determined. The residual code rate is determined according to the video source stream code rate, the retransmission code rate and the estimated bandwidth, the target redundancy code rate of the forward error correction strategy is determined according to the residual code rate, and the target redundancy code rate of the forward error correction strategy is determined according to the |
