摘要

在这项研究中，我们验证了一种配对比较方法，在这种方法中，评估者可以根据需要多次重复评估视频。我们使用该方法对8K 119.88 Hz (120 Hz)和59.94 Hz (60 Hz)视频进行主观评价，这些视频使用模拟8K 120 Hz编码器的软件进行压缩。实验结果证实:(1)该方法可以检测出视频质量之间的微小差异;(2)由于顺序效应不可忽略，必须对所有视频对进行评估;(3)适当的重复次数在4到9之间。

Validation of a Repeatable Pair Comparison Method

In this study, we verify a pair comparison method in which videos being evaluated can be repeated by the evaluators as many times as desired. We use the method to conduct a subjective evaluation of 8K 119.88 Hz (120 Hz) and 59.94 Hz (60 Hz) videos that were compressed using software that emulates an 8K 120 Hz encoder. The experimental results confirm that (1) this method can detect small differences between video qualities, (2) all video pairs must be evaluated because the order effect is not negligible, and (3) the appropriate number of repeats is between four and nine.
