This paper is essentially a treatment of the theoretical and practical aspects of the new IPTV service. The central part of the paper constitutes a detailed presentation of analysis scenarios and results, and addresses the following issues in particular: What influence does the encoding rate have of on QoE values? What effect does the most obtrusive impairment factor in a network, i.e. packet l...

The world of telecommunications continues to provide radical technologies. Offering the benefits of a superior television experience at reduced long-term costs, IPTV is the newest offering. Deployments, however, are slow to be rolled out; the hardware and software support necessary is not uniformly available. This paper examines the challenges in providing IPTV services and the limitations in d...

In this chapter1 we describe the integration of a recommender system into the production environment of Fastweb, one of the largest European IP Television (IPTV) providers. The recommender system implements both collaborative and content-based techniques, suitably tailored to the specific requirements of an IPTV architecture, such as the limited screen definition, the reduced navigation capabil...

The fault tolerance mechanism of the PIM-SM IP multicast routing protocol is investigated in order to be able to model it. The analysis is done by playing different fault scenarios on a mesh topology multicast test network built up by XORP routers in a virtualized environment. Different parameters of the PIM-SM and the OSPF protocols are examined if they influence and how they influence the out...
