The aim of this paper is to describe how QoS (Quality of Service) metrics such as packet delay can be used to optimise the routing algorithms used in a network where IP Television (IPTV) content is being distributed. We outline the usage of metric instrumentation in a network to gauge the bandwidth limits of the network and how to use this information to generate a model of network link utilisa...

This study examined the prevalence of 3 types of aggression on prime-time television during the spring of 2005. Verbal aggression was found to be the most prevalent, followed by indirect and physical. Physical aggression appeared more frequently among Caucasians and males. Female characters were more involved in indirect aggression, while verbal aggression was sex neutral. In general, minority ...

Seventy years ago Paul Lazarsfeld and colleagues found empirical evidence for a significant influence of the social context on media effects by interpersonal communication. Subsequently various theories in mass media science incorporated the social context as an independent or dependent variable. However, there is little empirical research that addresses the dynamics of media use within a socia...

The Internet supports a growing number of services ranging from legacy web browsing to the more recent online gaming or voice over IP. Among these services, some emerging network applications, such as IP television or video on demand, have stringent requirements in terms of guaranteed endtoend performance. These requirements translate into multiple quality of service (QoS) constraints related t...

Ethernet Passive Optical Network (EPON) is a point to multipoint network architecture and suitable for carrying Internet Protocol Television (IPTV) service because it provisions higher bandwidth for downstream, but it also cannot satisfy the bandwidth requirement of tens of thousands of IPTV channels and carry these channels simultaneously. Previous papers had proposed some multicast mechanisms...

Contemporary DTV technologies introduce the concept of interactivity to traditional TV broadcast services, provided that a data return channel exists. This paper proposes a wireless access network which is a result of the convergence of wireless data network technologies and digital broadcasting. The proposed network, which is being implemented in the frame of the EU-funded MAMBO IST project, c...
