A method of transmitting a stream of packets over a network, the method comprising the steps of: a transmitting device maintaining a measure of network quality; analyzing the measure of network quality so as to determine whether the bandwidth of the network is degrading, beyond a predetermined threshold, the network quality for a transmission over the network; the transmitting device determining a transmission bitrate and a proportion of redundancy in dependence on the analysis; the transmitting device packetising media data and redundancy data in dependence on the determined proportion to generate a stream of packets; and the transmitting device transmitting the generated stream at a rate commensurate with the determined transmission bitrate. |
