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…
Content-Driven Frame-Level Bit Prediction for Rate Control in Versatile Video Coding
Amritha Premkumar, Prajit T Rajendran, Vignesh V Menon +1
Rate control allocates bits efficiently across frames to meet a target bitrate while maintaining quality. Conventional two-pass rate control (2pRC) in Versatile Video Coding (VVC)…
Adaptive Resolution and Chroma Subsampling for Energy-Efficient Video Coding
Amritha Premkumar, Christian Herglotz
Conventional video encoders typically employ a fixed chroma subsampling format, such as YUV420, which may not optimally reflect variations in chroma detail across different types o…
Fast Multirate Encoding for 360° Video in OMAF Streaming Workflows
Amritha Premkumar, Christian Herglotz
Preparing high-quality 360-degree video for HTTP Adaptive Streaming requires encoding each sequence into multiple representations spanning different resolutions and quantization pa…
A High-Level Feature Model to Predict the Encoding Energy of a Hardware Video Encoder
Diwakara Reddy, Christian Herglotz, André Kaup
In today's society, live video streaming and user generated content streamed from battery powered devices are ubiquitous. Live streaming requires real-time video encoding, and hard…
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.…
