Adapting a Jitter Buffer

摘要

A receiver receives a first data stream and a second data stream from a transmitting device over a packet-based communication network, the first data stream being of a first media type (e.g. audio) and the second data stream being of a second media type (e.g. video). The first jitter buffer will buffer each of a plurality of portions of the first data stream as they are received via the receiver, and apply a de-jittering delay before outputting each portion of the first data stream (e.g. audio stream) to be played out through the receiving device. The jitter buffer controller receives information on the second data stream (e.g. video stream), and adapts the de-jittering delay of the first jitter buffer (e.g. audio jitter buffer) in dependence on the information on the second data stream (e.g. information on the video stream).

主权项

1. A receiving device comprising:
a receiver configured to receive a first data stream and a second data stream from a transmitting device over a packet-based communication network, the first data stream being of a first media type and the second data stream being of a second media type other than the first media type; at least a first jitter buffer configured to buffer each of a plurality of portions of the first data stream as the first data stream is received via the receiver, and to apply a de-jittering delay before outputting each portion of the first data stream to be played out through the receiving device; and a jitter buffer controller configured to receive information on the second data stream, and to adapt the de-jittering delay of the first jitter buffer in dependence on the information on the second stream.
