Abstract :
This paper describes the problems of channel change in multicast IPTV scenarios and the sources of delay during channel change. It provides an overview of approaches to reduce the tune-in delay and discusses their impact on image quality and required bandwidth. Finally, it makes recommendations on the applicability of the discussed solutions for selected scenarios.
