Abstract

An arrangement is provided for adapting the output bit rate of a multimedia source to the bandwidth available in a wireless network. Depending on the value of the available network idle time, at least a portion of the available network idle time may be used by the source to increase its output bit rate so that the network bandwidth may be more efficiently utilized. If the effective throughput of the network after the increase of source output bit rate drops significantly, the source may reduce its output bit rate until the effective throughput returns to the level before the source output bit rate increase. Additionally, packet delay and queue jitter information may be collected and used for queue rate adaptation as well as bandwidth adaptation.
