Problems solved by technology

[0002] When audio and video data is transmitted through the Internet, once the video data is lost due to forward reference, it often leads to problems such as static or blurred images, audio and video out of sync, and frame rate drop, while the loss of audio data will cause audio distortion and interruption or intermittent noise, audio interruption, etc.

Abstract

The invention discloses a data transmission method and device, electronic equipment and a storage medium, and relates to the technical field of communication, in particular to the field of voice and information streams. According to the specific implementation scheme, the packet loss rate of a target transmission link is obtained, a coding time interval is determined according to the packet loss rate, an original message generated in the coding time interval is coded to obtain a target message, and then the target message is sent to a receiving end through the target transmission link. The sending end can dynamically adjust the coding time interval according to the packet loss rate, so that bandwidth resources of a network can be effectively utilized, lost messages can be recovered in time, delay caused by retransmission of lost packets is effectively reduced, and the packet loss resistance is improved.

Description

technical field [0001] The present disclosure relates to the technical field of communication, in particular to the field of voice and information flow, and in particular to a data transmission method, device, electronic equipment and storage medium. Background technique [0002] When audio and video data is transmitted through the Internet, once the video data is lost due to forward reference, it often leads to problems such as static or blurred images, audio and video out of sync, and frame rate drop, while the loss of audio data will cause audio distortion and interruption Or intermittent noise, audio interruption, etc. [0003] Because the Internet uses unreliable protocols to transmit data, data loss often occurs on the network. Therefore, it is of great significance to effectively recover the packet loss caused by the network to ensure the quality of audio and video. Contents of the invention [0004] The present disclosure provides a method, device, device and stor...
