Real-time transmission data stream forward error correction method, system, device and storage medium

Abstract

The invention discloses a forward error correction method and equipment for a real-time transmitted data flow, and a computer readable storage medium. The method comprises the steps: screening out a first type of data packets meeting a preset first condition from the real-time transmitted data flow transmitted by a transmitting end; generating a redundancy packet through a preset encoder according to the first type of data packets, and transmitting the redundancy packet to a receiving end; screening a second type of data packets meeting a preset second condition from the real-time transmitted data flow transmitted to the receiving end and the redundancy packet, and a second type of redundancy packets; and generating a recovery packet through a preset decoder according to the second type of data packets and the second type of redundancy packets when a packet is detected to be lost. According to the scheme of the invention, the method enables a forward error correction mechanism to be applicable during the transmission of a network communication data flow between incompatible systems, and guarantees the quality of communication between heterogeneous real-time communication systems.

Description

technical field [0001] The present invention relates to the field of error control of network communication data streams, in particular to a forward error correction method, system, device and computer-readable storage medium for real-time transmission data streams. Background technique [0002] Packet loss is a common problem in network communication data flow transmission. In scenarios with high real-time requirements, the User Datagram Protocol (UDP) is generally used to transmit data. To overcome the problem of packet loss in UDP transmission, most real-time applications use Forward Error Correction (FEC) to recover lost packets. However, in practical applications, FEC mechanisms between different systems are generally incompatible, resulting in complete failure of the FEC function, thereby failing to reduce or eliminate the problem of packet loss. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a forward error correction met...
