This paper analyzes the relationship between video con tent and subjective video quality, and applies the results to rate control methods for streaming video services. In this analysis, we classify video programs into some groups in which large majority of users feel the same video quality. We determine the relationship by conducting an experiment with method of paired comparisons, and express that as equations by multiple linear regression analysis. Moreover, we apply the results to an actual encoding system, and we found out that the proposed schemes makes it possible to provide high-quality streaming services under various sys tem environments.
