<p>A device for transmitting a media stream over a network, the device comprising: a quality estimator configured to maintain a measure of network quality indicative of available bandwidth over the network; a configuration manager configured to: use the measure of network quality to detect a reduction in network quality indicative of a reduced available bandwidth and, responsive to detecting said reduction, estimate a first bitrate corresponding to the reduced available bandwidth; in response to estimating the first bitrate, determine a second bitrate lower than the first bitrate; and a transceiver configured to transmit the media stream at a transmission bitrate substantially equal to the second bitrate for a first period of time, wherein the configuration manager is further configured to cause an increase of the transmission bitrate from the second bitrate to the first bitrate over a second period of time.</p> |
