| Abstract(in English) | This report shows that text information improves task performance of the users in audio-video transmission over IP networks. Using three kinds of content types in subjective experiment, we measure task performance with and without subtitles; we then compare the two cases. The task performance is evaluated in terms of the ratio of correct answer. Even if the average amount of load traffic increases in the network, the ratio of correct answer keeps high values because of text information. As a result, we see that text information is effective in improving the task performance in IP networks. |
