RDE-MOGA: Automatic Selection of Rate-Distortion-Energy Control Points for Video Encoders Using Muti-Objetive Genetic Algorithm

摘要

Controlling energy consumption of video encoders is a complex multi-objective optimization problem of great importance. In this work we propose the RDE-MOGA, an multi-objective genetic algorithm capable of finding energetically efficient configurations for the HEVC encoder and replacing the current sensitivity analysis methodologies in the development of energy controllers. The utilization of our algorithm improved its efficiency in 60% whereas increasing the range of achievable reductions of the controller in at least 50%. Furthermore, the algorithm proved capable of sustaining 30% energy reduction at a cost of 3.45 BD-BR loss.
