In this paper we present a novel idea regarding transmission of next generation IPTV content. TodayIPTV systems utilize a COP structure tu provide streamsynchronization points for the clients, these are used whena channel switch occur. Since channel switches made byTV audiences are quite rare it is redundant to send synchronization opportunities in a GOP manner. The proposed design, synchronization frames fur channelswitching (SFCS), only requests synchronization frames when needed. We present a network traffic analysis modeland compare it with simulations. SFCS increases bandwidth utilization compared to traditional COP systemunder the presented transmission environment.
