An Efficient VoD Scheme Combining Fast Broadcasting with Patching

Today, mobile IPTV provides various multimedia services. Therefore, extensive researches on providing service continuity in the mobile IPTV environment are being conducted. Here reducing the user waiting time under the restriction of limited bandwidth is an important design issue in the video on-demand multicast service. In this paper we propose a scheme reducing the waiting time of a user wanting to start to view the video not from the beginning but from any point. The proposed scheme allows significantly reduced waiting time compared to the existing scheme for varying request rates and number of channels, as verified by computer simulation.
