新型冠状病毒疫情加速了视频会议和视频通信服务的采用，推动了视频数据流量的快速增长。对更高分辨率和质量的需求、对沉浸式视频格式的需求以及最新、更复杂的视频编解码器增加了数据中心和显示设备的能耗。在本文中，我们探索并比较了优化的最先进视频编解码器SVT-AV 1、VVenC/VVdeC、VP 9和x.265的能耗。此外，我们将能量使用与各种客观质量指标和不同分辨率的一组视频序列的压缩性能相一致。结果表明，从测试的编解码器和配置，SVTAV 1提供了最好的折衷之间的能量消耗和质量。报告的结果旨在作为可持续视频流的指南，同时不影响最终用户的体验质量。
The adoption of video conferencing and video communication services, accelerated by COVID-19, has driven a rapid increase in video data traffic. The demand for higher resolutions and quality, the need for immersive video formats, and the newest, more complex video codecs increase the energy consumption in data centers and display devices. In this paper, we explore and compare the energy consumption across optimized state-of-the-art video codecs, SVT-AV1, VVenC/VVdeC, VP9, and x.265. Furthermore, we align the energy usage with various objective quality metrics and the compression performance for a set of video sequences across different resolutions. The results indicate that from the tested codecs and configurations, SVTAV1 provides the best tradeoff between energy consumption and quality. The reported results aim to serve as a guide towards sustainable video streaming while not compromising the quality of experience of the end user.
