Multimedia Delivery Service using Multicast Technique on the Head- End-Network

In this paper, we propose Multimedia Delivery Service (MDS) for providing fluent multimedia services using multicast technique on the Head-end-Network. The implemented system is not conventional server-based multicast system but provides client-based on-demand one that has been lacked in conventional multicast delivery. The scheduler generates a multicast group address and port number when a client requests a service, then it sends them to multimedia server and client who request service. And then multimedia server transmits requested streams with a multicast group address and the client joins the group automatically. The scheduler assigns the same multicast group address when other clients request an identical multimedia within the same scheduling duration. Otherwise, it assigns another multicast group address to them.
