Jitter buffer adjustment method and system

Abstract

The invention provides a jitter buffer adjustment method and system thereof. The method for adjusting the jitter buffer includes: acquiring the packet loss rate and delay at the receiving end of data transmission; and adjusting the size of the jitter buffer at the receiving end according to the packet loss rate and delay at a preset period. The invention can perform jitter buffer self-adaptation according to network conditions, solve network delay jitter and at the same time ensure data transmission quality, and is especially suitable for network video data transmission.

Description

Technical field

[0001] The invention relates to the technical field of data transmission, in particular to a jitter buffer adjustment method and a jitter buffer adjustment system. Background technique

[0002] The development of network multimedia real-time communication has made many video interactive products emerge in an endless stream, and video transmission and codec technologies are also widely used in real-time network communication. However, whether in single-person network video technology or multi-person network video technology, network jitter delay is an inevitable problem. Jitter is a commonly used concept in QOS (Quality of Service), which means the degree of change in packet delay. If the network is congested, the queuing delay will affect the end-to-end delay, and cause the delay of packets transmitted through the same connection to be different, and jitter is used to describe the degree of such a delay change. Therefore, jitter will be an important parameter fo...

Examples

Embodiment Construction

[0032] See figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the jitter buffer adjustment method of the present invention.

[0033] The jitter buffer adjustment method includes the following steps:

[0034] S102: Obtain the packet loss rate and delay of the receiving end of the data transmission;

[0035] S104: Adjust the size of the jitter buffer of the receiving end according to the preset period according to the packet loss rate and delay.

[0036] The jitter buffer adjustment method of the present invention adaptively adjusts the size of the jitter buffer at the receiving end according to the packet loss rate and delay of the data transmission receiving end. Therefore, the size of the jitter buffer is adaptively changed, which can solve the problem of too small jitter buffer and too large packet loss rate caused by network jitter delay. It can also solve the problem of excessive network delay caused by excessive jitter buffer. The problem of data transmis...
