Abstract (en)
[origin: WO2015007868A1] Method of adaptive broadcasting of multimedia data streams Fi originating from a service provider (20), during a download between a receiving terminal (40) and a server (30), as a function of an energy criterion, comprising the following steps: · determining, for N representations Fi, at least one first energy index by calculating for each of the representations Fi of a multimedia segment, a value of energy Ei(t) consumed for decoding the representation Fi at the instant t, the maximum value of energy Emax(t) associated with the most energy consuming representation, and the values of the corresponding ratios formula (I) storing these values in a file associating with a representation Fi at least one ratio formula (I), • measuring the energy consumption used by the terminal in the course of the restoration of the representation Fi, and choosing another representation Fi or acting on the quality of restoration of the representation if the energy reserve of the terminal is insufficient to restore the content of the multimedia data stream on the basis of the representation Fi.
