The present invention concerns a method to control transmission data rate between a server (1) and a field of receivers (4, 6, 8), the server (1) being adapted to transmit data representative of an audiovisual content, the audiovisual content being available from said server (1) in at least two versions, the versions corresponding respectively to different transmission bit-rates, the server (1) 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, 6, 8), said transmission requests comprising a transmission parameter, the method comprising the steps of reception by a controller (2) of monitoring information from the receivers (4, 6, 8), the transmission of control parameters from the controller (2) to the receivers (4, 6, 8), the control parameters being defined from the monitoring information in order to define the transmission parameters of the requests from the receivers (4, 6, 8) to the server (1) or a reception parameter of at least one of the receivers (4, 6, 8). |
