It is difficult to watch TV contents in an active manner such that the user can interactively select TV contents, because TV is originally a broadcast information media. It is also difficult for users to judge whether the information of TV contents is valid because conventional TV contents are not directly linked with related or evidence information. One of the methods to cope with these problems is to provide complementary or comparative information of TV contents obtained from other media such as Web etc. In our research, using the topic structure proposed by Ma et al., we evaluated quality of TV contents, and visualize the quality. In this paper, we defined "contents coverage," "generality," and "social acceptance" as aspects of TV contents' quality, and examined to what extent there is complementary information against TV contents in Web pages. We also implemented a new system to complement TV contents by Web pages, called "TV contents spectrum analyzer," which visualizes the degrees of generality and social acceptance of TV contents using WWW.
