We have developed the communication system synchronized with video scene which is a topic duration defined according to its content. This paper evaluates whether we can understand the content of video more deeply or not by comments registered on this communication system. Two kinds of user tests using TV program videos are performed. One is the comparison of the communication system synchronized with semantic scene whose average duration is 72 seconds, short scene of five seconds and more shorter scene of each video frame. The other is the comparison of the communication system synchronized with viewing videos and independent of viewing videos.Experimental results show that the communication system synchronized with semantic scene can collect more comments which are related to video and include opinions and proposals based on experience and consideration.
