Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0028] The terms involved in the embodiments of the present application are described below.

[0029] VoIP (Voice over Internet Protocol, voice transmission based on Internet Protocol): a voice communication method based on IP (Internet Protocol, Internet Protocol) network. Specifically, the sending device encodes and compresses the audio data through an audio compression algorithm. According to the network transmission protocol standard, the encoded and compressed audio data is packaged to obtain the audio data packet, and the audio data packet is sent to the target IP address corresponding to the receiving end device through the IP network, and the receiving end device parses and decompresses the audio data packet After process...

Abstract

The invention discloses a data transmission method and device, a terminal and a storage medium, and belongs to the technical field of networks. The method comprises the following steps of making voicecriticality analysis on to-be-transmitted audios; obtaining key levels of to-be-transmitted audio frames in the to-be-transmitted audios; according to current redundancy multiples and redundancy multiple factors corresponding to the key levels of the to-be-transmitted audio frames, determining the to-be-transmitted audio frames; obtaining correction redundancy multiples of the to-be-transmitted audio frames, copying the to-be-transmitted audio frames according to the correction redundancy multiple of each audio frame to be transmitted to obtain at least one redundant data packet, and sending the at least one redundant data packet to the target terminal, so that the anti-packet loss effect of the network can be improved under the condition of not causing network congestion.

Description

technical field [0001] The present application relates to the field of network technologies, and in particular to a data transmission method, device, terminal and storage medium. Background technique [0002] With the development of network technology, VoIP (Voice over Internet Protocol, voice transmission based on Internet Protocol) technology can be used to communicate between terminals. Since the Internet is an unreliable transmission network, the audio data transmitted by the sending end based on the Internet is easy. Packet loss occurs. [0003] At present, network packet loss can be resisted by means of FEC (Forward Error Correction, forward error correction), PLC (Packet Loss Concealment, packet loss concealment), or ARQ (Automatic Repeat Request, automatic repeat request). However, FEC or PLC technology has poor anti-packet loss effect on continuous bursts of massive packet loss, and ARQ technology has poor anti-packet loss effect in some high-real-time scenarios. T...
