Abstract
The present invention relates to a receiver system in a communication system supporting packet-based communication (e.g., an IP-network), including a receiver, speech decoder and a jitter buffer for handling delay variations in the reception of a speech signal consisting of packets containing frames with encoded speech. A jitter buffer controller is provided for keeping information about the functional size of the jitter buffer and for providing the speech decoder with control information, such that the speech decoder, based on that information, provides a dynamic adaptation of the size of the jitter buffer using the received encoded, packetized speech signal. The invention also relates to a method of adapting the function size of the jitter buffer of a receiver system.
