Method for playing on a player of a client device a content streamed in a network

A method for playing on a player of a client device a content streamed in a network comprising a peer-to-peer network of client devices, said content consisting of a sequence of segments available in a plurality of quality levels, the player being configured so as to choose the quality level of the segments as a function of at least one parameter representative of a segment reception rate, according to an Adaptive BitRate, ABR, logic of the player;

• the client device comprising a first buffer for storing segments in a format adapted for transferring within the network, the method being characterized in that it comprises performing by a processing unit of the client device:
• (a) receiving from the player a request for a current segment at a first quality level;
• (b) determining, as a function of at least one parameter representative of a capacity of said peer-to-peer network, a second quality level;
• (c) estimating an optimal response delay such that providing the requested current segment at the expiration of said optimal response delay will cause the player to request according to its ABR logic a next segment at said second quality level, as a function of a model predicting the ABR logic of the player;
• (d) providing the requested current segment from the first buffer (M1) at the expiration of said estimated optimal response delay.
