Abstract: The Ultra High-Definition (UHD) standard introduces improvements in video quality across several dimensions. Although the first to be adopted commercially was the increase in resolution, features such as high frame rate and dynamic range, wide color gamut, and increased bit-depth offer important gains in the quality of experience of the end user. Nevertheless, each of these improvements comes with an associated cost in terms of storage, bandwidth, and energy consumption. In this paper, we first present key studies for evaluating the energy impact of streaming video and associated models. We then aim to quantify this cost for each UHD dimension, considering the distinct elements of an example streaming video chain and using concrete scenarios that combine different UHD features, an end-to-end model is employed to provide a comparative analysis. This allows us to evaluate the impact of each UHD characteristic and aid in guiding workflow choices for UHD content production and distribution.
