A data processing method and device, and a computer-readable storage medium

Abstract

The embodiment of the invention provides a data processing method and device and a computer readable storage medium. The method comprises the following steps: acquiring the ith multimedia data to be transmitted; when i is greater than 2, acquiring the i-1-th packet loss rate and i-2-th packet loss level; obtaining ith packet loss level according to the i-1-th packet loss rate, the i-2-th packet loss level, and fast increasing and slow decreasing relation between preset adjacent packet loss levels and a mapping relation between the preset packet loss level, the packet loss rate, the number of data packets and the number of redundant packets, and further determining the number of the ith data packets and the number of the ith redundant packets corresponding to the ith packet loss level; encoding the ith multimedia data to be transmitted according to the number of the ith data packets and the number of the ith redundant packets to obtain an ith data packet and an ith redundant packet; andsending the ith data packet and the ith redundant packet to a receiving terminal.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies in the Internet field, and in particular, to a data processing method and device, and a computer-readable storage medium. Background technique [0002] With the development of the multimedia Internet, more and more attention has been paid to the transmission efficiency and anti-interference of multimedia data in the transmission process. [0003] At present, for the transmission of multimedia data, anti-packet loss processing and the like are used to ensure the efficiency of data transmission. For example, anti-packet loss processing of IP-based voice transmission (VoIP, Voice over Internet Protocol) is generally implemented using a forward error correction (FEC, Forward Error Correction) technology. [0004] However, in the current anti-packet loss processing methods, the anti-packet loss strategy is relatively simple, which cannot meet the processing requirements in differen...

AI Technical Summary

Problems solved by technology

[0004] However, the current anti-packet loss processing methods all use a relatively simple anti-packet loss strategy, which cannot meet the processing requirements in different transmission situations.

For example, when using FEC technology, the FEC strategy uses fixed delay and fixed redundancy rate to process multimedia data, but it is difficult to determine the value of the delay and redundancy rate. If the delay and redundancy rate are too small, Poor anti-packet loss capability; high delay, poor experience, high redundancy rate, waste of bandwidth, unable to achieve better anti-packet loss effect according to actual transmission conditions, resulting in low accuracy of data transmission
