As multimedia contents rapidly spread and high-speed broadband IP network technologies develop, development of wire and wireless technologies, multimedia and image process technologies through IP network enables various types of service such as IPTV and VoIP. Individual service of communication companies and broadcasters coexist and evolve into a convergence service. Typical broadcast/communica...

IPTV services are the fastest growing television services in the world today. This is a bandwidth intensive service, requiring low latency and tight control of jitter. To guarantee the quality of service required, service providers opt to multicast all TV channels at all times to everywhere. However, a significant number of channels are rarely watched, which makes this a very inefficient delive...

Virtualized services can take benefit of statistical multiplexing across solicitations to yield momentous cost savings to the operator. However, achieving similar benefits with real-time services can be an encounter. In this paper, we pursue to lower a provider’s costs of real-time IPTV amenities through a virtualized IPTV design and through intelligent time shifting of service delivery. We tak...

IPTV has become the next generation of television due, in part, to its ability to support features that have been lacking in conventional broadcasting—for example, end-user interactivity, personalisation and localisation. Providers are also searching for the most efficient delivery methods to provide the greatest amount of contents at the lowest cost. At present IPTV uses IP multicast to delive...

The rapid development of the wireless access technologies challenged the IPTV platform operators to exploit this new medium, although the IPTV systems were designed for fixed transport, and they cannot easily accommodate to the mobile environment. Two aspect of this challenge are analyzed in my dissertation: the bandwidth allocation and packet retransmission; and the charging solutions. First, ...

One of the most important multimedia applications is Internet protocol TV (IPTV) for next-generation networks. IPTV provides triple-play services that require high-speed access networks with the functions of multicasting and quality of service (QoS) guarantees. Among optical access networks, Ethernet passive optical networks (EPONs) are regarded as among the best solutions to meet higher bandwi...

Virtual Home Library (VHL) is an integrated IT system that utilizes virtual reality technology and an IPTV set-top box (STB) to virtually construct a ‘library’ and the relevant reading environment on televisions in people’s home. Unlike the online e-book reading applications, Virtual Home Library can be applied on televisions-the world’s most convenient and most efficient communication tool. Pr...

BACKGROUND The use of Internet protocol television (IPTV) as a channel for consumer health information is a relatively under-explored area of medical Internet research. IPTV may afford new opportunities for health care service providers to provide health information and for consumers, patients, and caretakers to access health information. The technologies of Web 2.0 add a new and even less expl...
