The Internet Protocol Television has received much attention in recent years. It is a service that delivers media contents to costumers using the Real-time Transport Protocol and RTP Control Protocol. It brings many benefits for consumer and even for media distributors. IPTV is a specific application. It has only one sender and it should be able to offer its content to a huge number of receivers. As it is a new kind of service, there are still some problems to be solved. One of the most important is the Quality of Service (QoS) reporting delay and its dependence on the number of receivers in the session. The conventional RTP/RTCP architectures exceed acceptable range of the reporting interval with a relatively small number of receivers. This paper surveys the newest RTP/RTCP topologies and proposes a simulation model for further optimizations of algorithms and mathematical models for IPTV systems.
