| 摘要 |
<p>The present invention relates to a terminal unit in a communication system supporting packet based communication, e.g. an IP-network, including receiving means, speech decoding means (40) and a jitter buffer (20) for handling delay variations in the reception of a speech signal consisting of packets containing frames with encoded speech. Jitter buffer control means (50) are provided for keeping information about the functional size of the jitter buffer (20) and for providing the speech decoding means (40) with control information such that the speech decoding means (40), based on said information, provides for a dynamical adaptation of the size of the jitter buffer (20) by using the received encoded, packetized speech signal. The invention also relates to a method of adapting the functional size of the jitter buffer of a terminal unit.</p> |
