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…
The Bjøntegaard Bible -- Why your Way of Comparing Video Codecs May Be Wrong
Christian Herglotz, Hannah Och, Anna Meyer +8
In this paper, we provide an in-depth assessment on the Bjøntegaard Delta. We construct a large data set of video compression performance comparisons using a diverse set of metrics…
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…
Matched Quality Evaluation of Temporally Downsampled Videos with Non-Integer Factors
Christian Herglotz, Geetha Ramasubbu, André Kaup
Recent research has shown that temporal downsampling of high-frame-rate sequences can be exploited to improve the rate-distortion performance in video coding. However, until now, r…
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…
Optimized Decoding-Energy-Aware Encoding in Practical VVC Implementations
Matthias Kränzler, Adam Wieckowski, Geetha Ramasubbu +4
The optimization of the energy demand is crucial for modern video codecs. Previous studies show that the energy demand of VVC decoders can be improved by more than 50% if specific…
