Abstract: A method regulates transmission rate during a transmission of audio/video data over a network link between a sender and a receiver. The method comprises a first mode not using any return information from the receiver, executed at the start of the transmission, where the only possible modification to the transmission rate by the sender is an increase, and at least one second mode implemented following the first mode using at least one item of return information from the receiver. A change from the first mode to a second mode takes place when return information indicates that the transmission rate has reached a maximum rate available on the network link. The transmission rate is shared between a useful-data rate budget comprising the audio/video data and a secondary-data rate budget not necessary for the decoding of the audio/video data. The secondary budget is used for exploring the capacities of a network link.
