Table of Links Abstract and Introduction HDR Standards HDR Subjective Testing Workflow Conclusion and References Abstract—Over the past few years, there has been an increase in the demand and availability of High Dynamic Range displays and content. To ensure the production of high-quality materials, human evaluation is required. However, ascertaining whether the full playback pipeline is indeed HDR-compliant can be challenging. In this paper, we present a set of recommendations for conformance testing to validate various aspects of the testing workflow, including playback, displays, brightness, colours, and viewing environment. We assessed the effectiveness of HDR conversion techniques used in current standards development for making source materials. Additionally, we evaluate HDR display technologies, including OLED and LCD, using both consumer television and a reference monitor Index Terms—HDR, testing workflow, testing environment, playback, video coding. I. INTRODUCTION In recent years, HDR displays sales and content delivery have increased , . Oftentimes, the displayed video output may not always be true HDR. It is hard to confirm whether the playback is actually HDR or to cross-check a playback pipeline disruption. Validating this is important for quality assessment studies and it yields technical challenges. The development of standards testing protocols for subjective viewing environments for HDR videos is being led by the Video Quality Experts Group , International Telecommunication Union Recommendations, and the European Broadcasters Union for both televisions and broadcast applications –. Despite efforts made by previous authors to explore and adapt these techniques for HDR subjective studies –, there are still issues unresolved. Particularly, the configuration and technical validation of the playback pipeline is often not transparently presented in the literature. Thus, there is currently a lack of an HDR quality assessment framework that can be readily used to conform with these standards. Taking into account all the above, in this paper, we introduce an HDR quality assessment testing workflow , which comprises three important elements, a) the documentation of the playback pipeline, b) the HDR intermediate file conversions, and c) the testing environment.
