Abstract

The invention provides a real-time communication method and a real-time communication device. A real-time communication method for a first electronic device may comprise the steps of: receiving, from a server, audio packets of electronic devices, other than the first electronic device, communicating with the server; when an mth audio packet of a second electronic device in the other electronic devices is not received after the T_exp (m + n) or an audio frame of the mth audio packet at the current moment is not recovered by forward error correction after the T_exp (m + n), requesting a server to retransmit an (m + n) th audio packet of the second electronic device, m representing the serial number of the audio packet and being an integer equal to or greater than 1, n representing the number of redundant frames carried by the audio packets and is an integer equal to or greater than 1, and T_exp (m + n) representing estimated time at which the first electronic device receives the (m + n) th audio packet from the server in a normal communication case.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a real-time communication method and a real-time communication device. Background technique [0002] With the development of network technology, real-time communication technology is widely used. For example, video conferencing has become an indispensable communication tool among company employees when working from home, telecommuting or lack of physical meeting rooms. In the process of real-time communication, network packet loss is affected by the actual situation of the network and is unavoidable. When network packet loss occurs, the audio quality heard by participants will be poor, and even the voices of other participants cannot be heard clearly. Therefore, packet loss recovery of voice is very important during real-time communication. Contents of the invention [0003] The present disclosure provides a real-time communication method and a real-time ...
