Energy Reduction Opportunities in an HEVC Real-Time Encoder

Abstract : —High Efficiency Video Coding (HEVC) is one of the latest released video standards and offers up to 40% bitrate savings when compared to the widespread H.264/AVC standard, at the cost of a substantial complexity growth. Constraining the complexity of HEVC encoding is a challenging task for embedded applications based on a software encoder. In the last few years, the Internet of Thingss (IoTs) has become a reality. Forecoming applications are likely to boost mobile video demand to an unprecedented level. In this context, designing energy-efficient HEVC real-time encoders is becoming a major challenge for software and hardware designers. In this paper, an analysis is conducted of the energy reduction opportunities offered by an HEVC encoder. The energy reduction search space is demonstrated, and the impact on energy consumption of encoding tools at various levels of granularity is measured.
