Résumé

The production, transmission and display of video content requires significant amounts of energy. Whether broadcasting or streaming a video, its display on modern televisions is responsible for a significant proportion of the energy consumption. This paper proposes a framework for analyzing and processing High Dynamic Range (HDR) video frames that allows a modern screen to use less energy when displaying these frames. The content is analyzed prior to encoding and transmission, generating metadata that are attached to the content. After reception by a compatible display, the metadata is then used along with display parameters and user settings to adapt the peak brightness of the content. Picture quality is assessed objectively and subjectively, while in the meantime, we analyze the influence of the peak brightness over the power consumption of the screen. All these analysis provide us new insights to propose an energy-aware HDR rendering.
