Abstract

Method of adaptive broadcasting of multimedia data streams Fi originating from a service provider (20), during a download between a reception 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 to decode the representation Fi at the instant t, the maximum energy value Emax(t) associated with the most energy-consuming representation, and the values of the ratios corresponding E i ⁡ ( t ) E Max ⁡ ( t ) storing these values in a file associating with a representation Fi at least one ratio E i ⁡ ( t ) E Max ⁡ ( t ) , measuring the consumption of energy used by the terminal in the course of the playback of the representation Fi, and choosing another representation Fj or altering the quality of playback of the representation if the energy reserve of the terminal is insufficient to play back the content of the multimedia data stream on the basis of the representation Fi.
