| Abstract(in English) | In this paper, we propose an effective simple method for reducing bandwidth usage over an access link in the IPTV multicast delivery services. The IPTV services are required to meet rapid channel switching as well as conventional analog TV services, but these services encounter issues to achieve rapid channel switching. A significant problem is excess bandwidth consumption due to repeated channel switching behavior (channel zapping). This problem is caused by multicast leave processing, i.e., edge routers (ERs) cannot stop transmission immediately due to the leave processing, so that ERs are required to stop unnecessary distributions. The feature of the proposed method is a reduction of bandwidth usage on the access link. We show effectiveness of the proposed method through simulation evaluations. |
