METHOD AND APPARATUS FOR CONTROLLING A VOICE OVER INTERNET PROTOCOL (VOIP) DECODER WITH AN ADAPTIVE JITTER BUFFER

摘要

Controlling a Voice over Internet Protocol (VoIP) decoder with an adaptive jitter buffer to produce improved voice quality. The VoIP decoder controller may detect lost, misordered, or delayed packets, and may optimally choose a mitigation path based on the state of the VoIP decoder. The jitter buffering may be done ppmaply in the audio buffer or queue, and the depth of the queue may be set according to the variability of the packet inter-arrival time Finally, the VoIP decoder controller may automatically compensate for differences in the audio sampling clock in the VoIP encoder and decoder.
