The Power of Color
It’s a great time to be a video storyteller — yet as the bulk of color essence continues to increase, color transformations will become more costly. Color processing, such as blending, fading, chroma-subsampling and resizing will need to be processed quickly, with minimal error. Which raises the question: What does HDR and wide color gamut mean to MSO infrastructure and distribution? If nothing else, we’re at a moment in time where long-standing color uniformity issues can be corrected. Plus: A quantitative method to provide MSOs with video quality data that can be used to make operational, technological and product decisions. With it, MSOs can report overall video quality and provide data on specific distortions that can be introduced during video compression, as well as in format conversion (HDR-to-SDR, for example.) A key aspect of this approach is that it can be used to enhance PSNR and SSIM methods by leveraging principles of the human visual system — with minimal computational complexity. The objective is to show data and analysis that quantifies how HDR/WCG video quality can be made accurate, actionable and practical, particularly when content owners consider the various trade-offs between bandwidth, technology options and the viewer’s experience.
