Since two-way interactive broadcasting service began, remote controls have been fitted with 4 color buttons, which enables interaction and convenience to increase between users and content. Currently, diverse studies on IPTV are in progress. Particularly, as the mobile market rapidly grows, studies on mobile IPTV and on linkage with other media are constantly increasing. However, mobile IPTV ha...

IPTV is not a well-defined term and may be a source of ambiguity and sometimes confusion. This article describes the basic building blocks in order to clarify the difference between “IPTV” and what is increasingly being called “WebTV”. A comparison between IPTV and the DVB transmission schemes for satellite and cable is also made, providing some insight into the similarities between these deliv...

The promises of IPTV and related changes of the traditional TV environment are broadly discussed in the EuroiTV community. In this paper we present preliminary, qualitative results from a user evaluation conducted for an IPTV community platform focusing on usability and user experience issues. Our results show that major obstacles in the first phase of developing an IPTV community application a...

Abstract AIMS Brain metastases carry significant morbidity and mortality. The survival of patients with metastatic disease has improved due to systemic therapy advances conferring greater extracranial control. Optimal intracranial local control is probably surgical resection or stereotactic radiosurgery. However, there a cohort for whom this inappropriate, either patient fitness reasons. Tradit...

In traditional TV delivery systems, all the channels are pushed toward the subscribers. Therefore, user activities like channel switching have no effect on the provider network. Consequently, TV providers have felt no strong need to analyze and investigate the behavior of their subscribers. In IPTV networks, however, the situation is quite different. Channel switching activity of users imposes ...

The success of IPTV suggests that an expansion to mobile devices is likely. A key difference between IPTV delivery to mobile devices and broadband access is the possibility of vertical handovers, which can cause disruption to real-time video streaming. This paper proposes a lightweight form of IPTV transport based on negative acknowledgments. The performance of the scheme is analyzed in compari...

T he Quality of Service Metrics (QoSM) Committee of the Alliance for Telecommuni-cation Industry Standards (ATIS) Internet Protocol Television (IPTV) In teroperability Forum (IIF) is tasked with defining how objective quality metrics can provide meaningful IPTV performance measures. This group has reviewed current objective quality models as well as the processes by which such models are valida...

Convergence has recently become a key word in all industries including telecommunications. The most noted case is the media and IT convergence in Korea. The reason for this is that broadcasting is under the influence of IT technology development, such as broadband, digitalized, and interactive trajectories. Mobile Internet Protocol Television (IPTV) is one of the converging technologies, which ...

In recent years, IPTV has received an increasing amount of interest from the industry, commercial providers and the research community, alike. In this context, standardization bodies, such as ETSI and ITU-T, are specifying the architecture of IPTV systems based on IP multicast. An interesting alternative to support the IPTV service delivery relies on the Peer-to-Peer (P2P) paradigm to distribut...

It is absolutely essential to implement advanced IP network technologies such as QoS, Multicast, High Availability, and Security in order to provide real-time services like IPTV via IP backbone network. In reality, the existing commercial networks of internet service providers are subject to certain technical difficulties and limitations in embodying those technologies. On-going research effort...
