Abstract

The invention discloses a data transmission method, a terminal and a computer readable storage medium. The data transmission method comprises the following steps: processing to-be-transmitted data based on a real-time transport protocol (RTP) to obtain a plurality of RTP data fragments; performing forward error correction coding on the plurality of RTP data fragments to obtain a plurality of pieces of error correction data; obtaining an RTP error correction packet through the error correction data, wherein the RTP error correction packet comprises the error correction data and an RTP packet header, and the RTP packet header comprises error correction information; and sending the RTP error correction packet to a receiving end. According to the data transmission method provided by the invention, on one hand, the receiving end can recover the lost data packet, and on the other hand, the size of the data packet can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a data transmission method, a terminal, and a computer-readable storage medium. Background technique [0002] When video media is transmitted on the network, some video data packets are likely to be lost due to network equipment forwarding, transmission channel congestion, and transmission bandwidth limitations, which in turn leads to poor user experience such as video playback freezes, blurred screens, and audio and video out of sync. [0003] Aiming at the problem of packet loss, various methods have been proposed to solve or reduce the impact of packet loss. Among them, forward error correction (Forward Error Correction, FEC) technology is a technology widely used in communication systems. It encodes a set of erasure codes with certain rules before data transmission. When the receiving end finds that the channel has data loss The data is restored accordi...
