Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switch communications. The de-jitter buffer methods and apparatus presented avoid playback of underflows while balancing end-to-end delay. In one example, the de-jitter buffer is recalculated at the beginning of each talkspurt. In another example, talkspurt packets are compressed upon receipt of all remaining packets.

L'invention concerne un tampon suppresseur de gigue adaptatif destiné à un système vocal sur l'Internet (VoIP) pour des communications par commutation de paquets. Les procédés de tampon suppresseur de gigue et appareils associés selon l'invention permettent d'éviter une lecture de soupassements et équilibrent en même temps un retard de bout en bout. Dans un exemple, le tampon suppresseur de gigue est recalculé au début de chaque impulsion vocale. Dans un autre exemple, les paquets d'impulsion vocale sont comprimés au moment de la réception de tous les paquets restants.
