摘要

Method to provideg video chunks to a client entity (C) using a request-response protocol. Each video chunk is available at a server entity (S) as a plurality of encoded video chunks encoded according to respective quality levels. The method includes the steps of : - the server entity sending to the client entity information on the different quality levels, - the client entity making a selection of one quality level of the different quality levels based on criteria related to local transfer bandwidth related parameters, - the client entity requesting the server entity to transfer to it encoded chunks encoded in that one chunk quality level and - the server entity sending the encoded chunks encoded according to that one chunk quality level to said client entity, - the server entity sending to the client entity additional information related to a transfer time of the encoded chunks from the server entity to the client entity, and - the client entity in making the selection of the one quality level taking into account also the additional information.
