Energy-Aware Frame Rate Selection for Video Coding
Geetha Ramasubbu, Andrè Kaup, Christian Herglotz
The main contributions of this paper are twofold: First, we present an in-depth analysis of the impact of frame rate reductions on the visual quality of the video and the encoding…
Modeling the Energy Consumption of the HEVC Software Encoding Process using Processor events
Geetha Ramasubbu, Andrè Kaup, Christian Herglotz
Developing energy-efficient video encoding algorithms is highly important due to the high processing complexities and, consequently, the high energy demand of the encoding process.…
Towards Video Codec Performance Evaluation: A Rate-Energy-Distortion Perspective
Geetha Ramasubbu, André Kaup, Christian Herglotz
The Bjøntegaard Delta rate (BD-rate) objectively assesses the coding efficiency of video codecs using the rate-distortion (R-D) performance but overlooks encoding energy, which is…
A Bit Stream Feature-Based Energy Estimator for HEVC Software Encoding
Geetha Ramasubbu, André Kaup, Christian Herglotz
The total energy consumption of today's video coding systems is globally significant and emphasizes the need for sustainable video coder applications. To develop such sustainable v…
Modeling the HEVC Encoding Energy Using the Encoder Processing Time
Geetha Ramasubbu, André Kaup, Christian Herglotz
The global significance of energy consumption of video communication renders research on the energy need of video coding an important task. To do so, usually, a dedicated setup is…
