Abstract: A method for controlling a player of a client device comprising a cache for storing segments of a data stream in a format adapted for transfers within a P2P network, the player being configured to play segments of the data stream stored in a buffer, and whenever an amount of data pending for playback in the buffer is less than a threshold parameter of the player, request other segments of the data stream to be transferred from the peer-to-peer cache to the buffer, wherein the method comprises: determining a download completion ratio associated with a reference segment of the data stream; computing a score depending on the download completion ratio, changing the threshold parameter of the player from a first value to a second value greater than the first value only if the score meets a predefined condition.
