Embodiment Construction

[0057] The following description is given in a completely non-limiting way of illustration in order to correctly explain the method according to the invention in case a user wishes to download a video representation or a video stream onto his terminal. The term terminal in the examples given denotes a mobile phone, tablet or connected device enabling reception of multimedia streams. The invention may be used in the context of multimedia data such as audio or multimedia streams without departing from the scope of the invention. The term multimedia stream can denote different programs such as video games, movies, music, etc. distributed over a communication network. Basic properties of histograms enable the description or characterization of histograms. This may include a population of values ​​accounted for in each class of the histogram, or accounted for above or below various thresholds.

Abstract

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.

Description

technical field [0001] The subject of the invention relates to a method and a system allowing adaptive broadcasting of multimedia streams (selection of representations to be downloaded) between a server and one or more terminals by exploiting at least one criterion of the energy consumed by the terminals. For example, for mobile terminals with limited self-sufficiency, it is especially suitable when a user wishes to view video broadcasts via the Internet. Background technique [0002] Typically, data content is distributed via servers managed by service providers. Therefore, in order to receive specific content, a user sends a request to a server that stores that content. Typically, the user receives these data on a mobile phone, tablet or any other equivalent device. The pervasiveness of high bitrate access (such as 4G networks) and the emergence of the HEVC high-efficiency video coding compression standard will lead to significantly more online video usage than currently...
