IPTV is defined as multimedia services delivered over IP based networks. This can be performed using the PIM-SM multicast routing architecture which enable IP multicast routing on existing IP networks. The RP is required for network running PIM-SM, and the RP location changes the efficiency of multicast data packets. In general, the PIM-SM is consisted of a shared tree for keep-alive packets and a source-based tree for sending out large data. Therefore, the RP utilization is very high when the access network uses PIM-SM. And PIM-SM protocol cannot be applied in different architectures with access networks such as PON, HFC. In this paper, we propose a new PIM-SM protocol which reduces processes of traditional PIM-SM protocol in IPTV services. The proposed a new PIM-SM protocol can reduce the number of processes for RPT configuration and can deliver multicast data packets immediately through the SPT. Therefore, the RP utilization in extended PIM-SM improves than traditional PIM-SM.
