AI Technical Summary

Problems solved by technology

For example, when the network becomes congested, the sending device can reduce the transmission bandwidth of the media stream by reducing the quality of the media, so that the media stream does not further congest the network, and it takes less time for packets to reach the receiving device through the congested network

Abstract

A method of identifying a network condition between a pair of network devices, wherein one of the devices comprises a jitter buffer for storing packets received via a network, the method comprising: monitoring a measure of delay in receiving media packets over the network; monitoring a size of the jitter buffer; and identifying a network condition in dependence on a change in the measure of delayand a variation in the size of the jitter buffer.

Description

Background technique [0001] The present invention relates to methods and devices for identifying network status. [0002] Real-time streaming of multimedia content over the Internet has become an increasingly common application in recent years. A wide range of multimedia applications such as on-demand TV, live TV viewing, audio streaming, video conferencing, web conferencing, video telephony, Voice over Internet Protocol (VoIP), and many others rely on end-to-end streaming solutions. Unlike "downloading" media files (which can be retrieved first at a "non-real-time" time and played back later), streaming media applications require the media source to encode the media signal and transmit it over the network to the media sink, which This media signal must be decoded and played back in real time. [0003] Problems may arise when streaming media across a network, such as the Internet. For example, a network link between a pair of network endpoints may become congested, which ma...
