The present invention concerns a method to control the transmission and transmission data rate between at least two servers (1,2) and a receiver (4), the servers (1,2) being adapted to transmit data representative of an audiovisual content, the audiovisual content being available from each of said at least two servers (1,2) in at least two versions, the versions corresponding respectively to different transmission bit-rates, the servers (1,2) being adapted to transmit audiovisual contents in successive parts, each of said successive parts being chosen as one of at least two versions in response to transmission requests sent by the receivers (4), said transmission requests comprising a transmission parameter, the method comprising the steps of reception by a controller (6) of information from the receiver (4), the transmission of at least a control parameter from the controller (6) to the receivers (4), the at least one control parameter being defined from the information in order to define the transmission parameters of the requests from the receiver (4) to one of at least two servers (1,2) or a reception parameter of the receiver (4).
