Due to the enormous improvement of networking technologies and the advances in media encoding and compression techniques, IPTV becomes one of the fastest growing services in the Internet. When offered via wireless technologies (e.g., WiMAX), IPTV can pave the way for quad-play in next generation networks and ubiquitous delivery. IPTV subscribers expect the same or even better Quality of Experie...

Internet television (IPTV) is rapidly gaining popularity and is being widely deployed in content delivery networks on the Internet. In order to pro-actively deliver optimum user Quality of Experience (QoE) for IPTV, service providers need to identify network bottlenecks in real-time. In this paper, we develop psycho-acousticvisual models that can predict user QoE of multimedia applications in r...

In this paper a proof of concept infrastructure for the delivery of standardized IMS-based IPTV services driven by the IPTV enabled Open IMS Playground at Fraunhofer FOKUS will be presented. The so called Media Interoperability Lab represents one of the world’s first real world test beds for these kind of services. This has been achieved by actively guiding the different SDOs work with a focus ...

Triple-play (high-speed Internet, Telephone, and TV) in which IPTV is an important factor is now largely offered by many Internet Service Providers (ISP). But being a combined business model, it has some limits because of price and equipment requirements. By that reason, P2P-IPTV appeared as a competitor. With low price and does not require deluxe configuration at end-user computer, P2P-IPTV be...

Network service providers have to consider both network and multimedia processing factors to guarantee adaptable network service level of IPTV service. In the view of network service customers, it is a good way to require network service providers to ...

As the IMS provides session establishment, QoS parameter negotiation, authentication and accounting it is an overlay architecture well qualified for session signaling concerning IPTV scenarios. The management of the signaling can be integrated as an application into an IPTV Application Server. The IPTV AS is further responsible for all necessary media signaling towards a proper IPTV media serve...

 Abstract—In this paper, we analyze user behaviors in Internet Protocol television (IPTV). We propose a novel coupled LDA model, which considers topic of TV programs viewed as well as the timestamps of the viewing behaviors, in order to capture the inherent viewing patterns of the users along the topic as well as the time dimensions. Based on the coupled LDA model, we further summarize the beh...
