分析了面向用户的流媒体服务中视频内容与主观视频质量之间的关系。在这项分析中，我们进行主观评估，通过使用各种视频节目，并提出了一种方法，将视频节目分成几组，其中绝大多数用户感觉相同的视频质量。通过将不同的控制方法应用于从所提出的方法获得的每个组，可以完成具有高水平的用户满意度的控制。我们还显示了根据视频内容的码率控制的必要性，通过比较基于视觉参数的分类结果与基于评估结果。
This paper analyzes relationship between video contents and subjective video quality for user-oriented streaming services. In this analysis, we conduct subjective assessments by using various kinds of video programs, and propose a method classifying video programs into some groups in which a large majority of users feel the same video quality. The control with a high level of user satisfaction can be done by applying different control method to each group obtained from the proposed method. We also show the necessity of rate control according to video contents by comparing a classification result based on vision parameters with that based on the assessment result.
