Modeling the energy consumption of HEVC P- and B-frame decoding

Video decoding on portable devices such as smartphones or tablet PCs requires a considerable amount of battery power, shortening their operating time significantly. Hence, tools aiming at minimizing the decoding energy are of special interest. To this end, this paper presents a novel model capable of estimating the energy consumed when decoding an HEVC-coded video. This information can be used to optimize implementations and improve the encoding procedure. An accurate and a more convenient simple model is proposed that, for the evaluated set of test videos, achieved an average relative estimation error of 2.34% and 3.63%, respectively.
