超高清视频技术要素主观评价研究

Research on Subjective Evaluation of Ultra High Definition Video Technology Elements

本文研究了超高清视频技术要素对主观体验的影响,通过主观评价实验量化了分辨率、动态范围、帧率和量化深度等技术要素的提升对观看体验的贡献。实验结果显示,技术要素的提升对改善主观体验有积极作用,其中,4K分辨率、HDR技术、高帧率对主观体验的影响较为显著,2K HDR在某些情况下优于4K SDR。该研究为超高清视频技术的发展提供了参考。

This article investigates the impact of ultra-high definition video technology elements on subjective experience,and quantifies the contribution of improving technical elements such as resolution,dynamic range,frame rate,and quantization depth to the viewing experience through subjective evaluation experiments.The results show that the improvement of technical elements has a positive effect on improving subjective experience.Among them,4K resolution,HDR technology,and high frame rate have a more significant impact on subjective experience,and 2K HDR is better than 4K SDR in some cases.This study provides a reference for the development of ultra high definition video technology.
