On this webpage, an HEVC encoder for generating decoding energy saving bit streams can be downloaded. The code is based on HM-14.0 and freely available for personal use (under the GNU-GPL-license). It can be compiled for Windows as well as for Linux. Read the README_DERDO.txt for more information.
Next to the classic QP value, which is used to control the visual quality of the output bit stream, a new variable t can be chosen to control the rate-energy trade-off. t=0 means classic RDO, t=1 means pure decoding-energy-distortion optimization (without considering the rate), values in between can be used to optimize both rate and energy at the same time.
As a result, if rate increases are acceptable, decoding energy can be saved which is especially beneficial for mobile applications.
