Abstract
BUFFER DE-JITTER ADAPTATIVO PARA VOZ SOBRE IP. Trata-se de um Buffer De-Jitter Adaptativo para Voz sobre IP (VoIP) para comunicações comutadas por pacote. Os métodos e o equipamento do buffer de-jitter apresentados evitam a reprodução de underflows ao mesmo tempo em que equilibram o retardo fim-a-fim. Em um exemplo, o buffer dejitter é recalculado no começo de cada jorro de fala. Em outro exemplo, os pacotes do jorro de fala são compactados quando do recebimento de todos os pacotes restantes.
