SIP-Based Management Architecture for Large-Scale Home Conferencing Using IPTV

Abstract

Recent advances in home network technology, combined with IP-based home appliances such as IPTV, can provide high-quality IP-based video conferencing service at relatively low cost. This paper presents SIP-based management architecture for large-scale home conferencing service using IPTV. In the proposed architecture, we extended the protocol stack of IPTV for the support of SIP-based signaling, and applied IPTV to large-scale home conferencing. High scalability of the proposed architecture is achieved by coordinated distributed conference control and media processing. The signaling procedures for the integrated control of IPTV have been designed in detail for SIP-based conferencing service. The performance of the proposed system has been evaluated by simulation. The simulation results show that the proposed architecture greatly improves scalability 1 .
