1. A method for playing on a player of a client device a content streamed in a network, 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 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 that the player will request according to its ABR logic a next segment at a second quality level after said requested current segment is provided from the first buffer memory, using a model predicting the ABR logic of the player; and

(c) if said next segment is not present at said second quality level in the first buffer memory, fetching said next segment at said second quality level from the network, wherein

said model is trained from a database of training examples each associating a vector of measured parameters representative of a segment reception rate with the corresponding quality level subsequently chosen by the player according to its ABR logic.
