- Additional information
- This was the first empirical evaluation of the energy usage of different video encoding / decoding (codec) mechanisms, including codecs commonly known as H.264 (aka MPEG4 part 10), H.265 (aka High Efficiency Video Codec, HEVC), VP8, and VP9: between them, these account for a majority of the world's video content. The work included a simple, desktop measurement methodology and the definition of the first measurement-based metric that combined energy usage and objective Quality of Experience (QoE) for video, so allowing direct comparison of the energy usage of different codecs. The work also included estimates for reductions in carbon emissions, and models for changes to user interfaces to include energy labelling of Internet video for users.
