On the Immersive Properties of High Dynamic Range Video

This paper presents the results from two studies which used a dual-task methodology to measure an audience's experience of immersion while watching video under typical television viewing conditions. Immersion was measured while participants watched either a high dynamic range, wide color gamut video or a standard dynamic range, standard color gamut video, in high definition or ultra-high definition. Other video parameters were carefully measured and controlled. The study found that high dynamic range, wide color gamut video is significantly more immersive than standard dynamic range, standard color gamut video in the chosen configuration. However, there was no evidence of significant differences in immersion between high-definition and ultra-high-definition resolutions.
