Embodiment Construction

[0025] see figure 1 , figure 1 is a schematic flowchart of the first embodiment of the jitter buffer adjustment method of the present invention.

[0026] The jitter buffer adjustment method includes the following steps:

[0027] S102, acquiring the packet loss rate and delay of the receiving end of the data transmission;

[0028] S104. According to the packet loss rate and delay, adjust the size of the jitter buffer of the receiving end according to a preset period.

[0029] The jitter buffer adjusting 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 receiving end of data transmission. Therefore, the size of the jitter buffer is adaptively changed, which can solve the problem that the jitter buffer is too small to deal with the excessive packet loss rate caused by network jitter delay, and can also solve the problem of excessive network delay caused by too large jitter bu...

Abstract

The invention provides a method and a system for regulating a jitter buffer. The method for regulating the jitter buffer comprises the following steps: acquiring the packet loss rate and the time delay of a data transmission receiving end; regulating the size of the jitter buffer of the receiving end by a preset period according to the packet loss rate and the time delay. Jitter buffer self-adaptation can be carried out according to network conditions, and data transmission quality can be ensured when a network delay jitter is solved. The method and the system are particularly suitable for the transmission of network video data.

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 led to the emergence of many video interactive products, and video transmission and codec technologies are also widely used in real-time network communication. However, no matter in single-person network video technology or multi-person network video technology, network jitter delay is an inevitable problem. Jitter is a concept commonly used in QOS (Quality of Service), which means the variation degree of 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 vary, and jitter is used to describe the degree of such delay variation. Therefore, jitter will be an important parameter for real-tim...
