With the advent of multi-channel TV services, a prohibited amount of IPTV program contents becomes available to user’s sides. Furthermore, the number of IPTV service providers is rapidly increasing over internets. Therefore such information overload requires large amounts of efforts for users to search and navigate the program contents that they like to watch. In this paper, we incorporate coll...

In this paper, we explore the use of a set of potential ‘alternative’, emotional state and engagement-related measures of QoE and investigate how they relate to traditional QoE measures. To this end, we present results from a living room lab study (N=28) in which the impact of slicing errors on QoE was investigated. Our findings indicate significant differences in QoE between the three used err...

In this paper we discuss information interoperability, focusing on design and implementation of service and content metadata solutions for crossdomain IPTV services. We approach the problem by discussing experience sharing in interactive TV, and relate it to necessary service platform facilitators, such as: interactive TV sessions, cross-domain service framework and metadata integration (servic...

A technology for multicasting packetized multimedia streams such as IPTV over the Internet backbone is proposed and explored through extensive simulations. An RSVP or DiffServ algorithm is used to reserve resources (i.e., bandwidth and buffer space) in each packet-switched IP router in an IP multicast tree. Each IP router uses an Input-Queued (IQ) switch architecture with unity speedup. A recen...

The Internet is currently experiencing one of the most important challenges in terms of content distribution since its first uses as a medium for content delivery: users from passive downloaders and browsers are moving towards content producers and publishers. They often distribute and retrieve multimedia contents establishing network communities. This is the case of peer-to-peer IPTV communiti...

Das Internet ermöglicht den Zugang zu einer Vielzahl von Diensten wie z.B. YouTube, Skype, Cloud Storage oder IPTV. Die vom Benutzer erfahrene Quality of Experience (QoE) oder Dienstgüte ist jedoch oftmals nicht optimal, da die Netze keine Kenntnis über die Dienste haben deren Daten sie transportieren. Daher werden IPTV Pakete, die in Echtzeit ausgeliefert werden müssen, genauso behandelt wie z...

In this paper, we consider the problem of providing IPTV services by designing routing strategies to handle catastrophic failures in a backbone network. In a typical IPTV architecture, broadcast TV is distributed from two sources to multiple destinations (for resiliency). The aim of this paper is to develop a solution technique for supporting IPTV services in a reliable and cost effective manne...

This paper proposes an effective channel management framework which analyzes the user channel surfing behavior and constructs fast channel change stream consisting of user preferred channels. The usual channel delay is obliterated if the user requested channel is found at the Set-Top-Box (STB).
