Abstract:
The present paper analyzes the relationship between video content and subjective video quality for user-centered streaming services. In this analysis, we conduct subjective assessments using various types of video programs, and propose a method of classifying video programs into a number of groups that are thought by a large majority of users to have the same video quality. Control to a high level of user satisfaction can be performed by applying a different control method to each group obtained using the proposed method. In addition, we demonstrate the necessity of rate control according to video content by comparing a classification result based on vision parameters with the classification result based on the assessment result.
