Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0044] FEC is a forward error correction technology. Commonly used FEC algorithms include redundancy, XOR, and RS coding. Generally, the data sending end sends the payload data together with a certain redundant error correction code with the characteristics of the signal itself. The data receiving end performs error detection on the data, and if an error is found, the error correction code is used to correct the error. ...

Abstract

The invention provides a data transmission method and device, terminal equipment and a storage medium. The data transmission method comprises the steps: carrying out forward error correction (FEC) coding on to-be-transmitted media data according to a preset anti-packet-loss mode, and generating a to-be-transmitted data packet which comprises N media data packets, distributing serial numbers for the N media data packets according to a preset rule; sending the to-be-transmitted data to a data receiving device; receiving a network packet loss feature sent by the data receiving device, wherein the network packet loss feature is determined according to a serial number of a media data packet in the received data packet and a preset rule after the data receiving device receives the data packet; and adjusting the preset anti-packet-loss mode according to network packet loss characteristics.

Description

technical field [0001] The present application relates to communication technology, and in particular to a data transmission method, device, terminal equipment and storage medium. Background technique [0002] Forward Error Correction (FEC) is a method to increase the reliability of data communication. Forward error correction technology, before the signal is sent into the transmission channel, the encoding process is performed according to a certain algorithm in advance, and the redundant code with the characteristics of the signal itself is added. After receiving the signal, the data receiving end decodes the received signal according to the corresponding algorithm, so as to find out the error code generated during the transmission and correct it. [0003] FEC has two anti-packet loss modes: random and burst. The two anti-packet loss modes correspond to two encoding matrix types respectively. Only when the corresponding anti-packet loss mode or the corresponding encoding...
