Interactive video network transmission method and system, recording and broadcasting host and storage medium

The embodiment of the invention provides an interactive video network transmission method and system, a recording and broadcasting host and a storage medium, the network quality of a main recording and broadcasting host is monitored, when the network quality of the main recording and broadcasting host meets a preset congestion condition, to-be-transmitted video data is transmitted in a picture transmission mode by using a TCP transmission protocol, and a slave recording and broadcasting host transmits the to-be-transmitted video data to the recording and broadcasting host. And the receiving module is used for receiving video data transmitted in a picture transmission mode under the condition that the network quality of the main recording and broadcasting host meets a first preset congestion condition. Through a TCP congestion control mechanism, when the broadband is insufficient, the transmission rate of the TCP is actively reduced, packet loss and invalid transmission are avoided, the network transmission qu
