This paper reports an examination of the perceptual video quality space for video degradations. Therefore, we conducted an experiment, which investigates whether the perceptual video quality dimensions obtained in a head-and-shoulder videotelephony setting are also valid for other video content. The method of Direct Scaling is used for directly assessing the identified perceptual quality dimensions. This method makes it possible to assess more test conditions in the same time, due to the reduced experimental effort. Besides the ratings of the perceptual video quality dimensions, the test participants are also asked to rate the overall video quality. This allows drawing conclusions of the composition of the underlying quality dimensions to form overall quality for video. The results of the experiment are compared to the ratings obtained from subjective testing in the domain of video telephony.
