This paper handles features of the test-bed in detail including conceptual pictures. Also, the per-phase test-bed construction is described in terms of goal and action item. The utilization of the IPTV2.0 demonstration test-bed throughout the entire process from project planning to service launching and the expected effectiveness are suggested. Specifically, some media services show what kinds of...
This paper introduces the IP Multimedia Subsystem (IMS) and its terminal application. It develops a software system of the IMS intelligent terminal based on Windows Mobile. The paper also introduces the development environment and the overall structure of the IMS terminal and describes the main thread. It presents the complete process of the Internet Protocol Television (IPTV) in detail through elaborating...
Session Initiation Protocol (SIP) has been widely applied to multimedia telephony service in Broadband Converged Network (BCN). SIP is also adopted as the basic signalling protocol of VoIP and 3GPP. IP multimedia subsystem (IMS) is a SIP based multimedia telecommunication infrastructure in 3GPP. Recently, many mobile operators have selected IMS as a core infrastructure because IMS has a flexible architecture...
This paper is about the scheme to provide number portability to additional service of mobile IPTV system. In this paper, we present system and packet structure to realize number portability of additional service of mobile IPTV.
Internet protocol TV (IPTV) has emerged as a new platform in converged environments. In particular, due to its support for the convergence of devices, IPTV allows almost every IP-enabled terminal to simultaneously consume the same rich media service delivered over an IP-based network. However, this convergence potentially leads to a significant decrease in both quality of service (QoS) and quality...
This paper is about the scheme to provide additional service on mobile terminal device by using mobile IPTV system. In this paper, we represent system and packet structure to realize additional service of mobile IPTV.
Internet Protocol Television (IPTV) is an emerging and killer application for WiMAX networks, which takes advantage of multicasting mechanisms to efficiently deliver the video data to groups of subscribers. In this paper, we propose a Reception-rate-tracking Opportunistic Multicast Scheduling (ROMS) to enhance the performance of scalable IPTV layered multicasting over WiMAX networks. The proposed...
This paper discusses the necessary media processing functional requirements for new multimedia services in core networks, and proposes an open system architecture to addresses them. The system architecture provides efficient transcoding, rate adaptation, filtering, scaling and other functions needed for video communications, IPTV and 3DTV applications over networks.
Since digital media is being combined into all aspects of our lives and an ubiquitous broadband networks are being surfaced, people expect to extend the consumption of these services on any device, anytime and anywhere. This new demand requires the flexible service adaptation to user requirements and to device capabilities. Specifically, various access networks and devices with different capabilities,...
This paper presents IMS architecture resulting from SYSTERMIN@L, a project running from mid 2007 to mid 2009. The project addresses services and network convergence from the customer terminals point of view: ldquoselect all your services on the terminal wherever you are.rdquo The basic idea is to consider terminals interacting in a system configuration as opposed to independent standalone devices...
This paper presents concept and realized solution of media collaboration system that supports the various different media of broadcasting and communications as well as fixed and mobile environments with the goal of implementing more advanced IPTV services. This article gives an overview of its capabilities and roles of its main technologies. By implementing cooperative combinations of different media,...
There is a rapid growth and evolution in the area of telecommunications and network operators are expected to provide seamless integration of all communication applications on a single system. In these circumstances IMS has emerged out as a key player. IMS is basically a network architecture consisting of an IP-based core network connected to multiple access networks to provide a converged service...
Wireless IPTV (Internet protocol television) aims to make the traditional IPTV and related services available to users anywhere, anytime, on any device, and through any network. Mobile streaming TV is one of the alternatives to deploy such a system, others are DVB-H or MediaFLO. In this paper we propose an architecture to distribute contents to different access networks, in order to create a triple...
The active TV concept offers solutions providing end users with easy access to new audiovisual services and applications from various terminals. A unique experience with new types of group interactions becomes possible in the form of advanced local and community services. To enable the delivery of such services with the required quality and security, active TV addresses the problem of pushing a part...
Convergence is a key word in all of industries as well as telecommunication industry recently. The most noted case is media (specially, broadcasting) and IT convergent one in Korea. The reason is that broadcasting is under the influence of IT technology development trajectory such as digitalized, broadband, interactive and so on. For example, there are mobile TV (in Korea, DMB), IPTV, and mobile IPTV...
There is a visible evolution in the telecommunication networks from pure voice traffic to the service provisioning. In this article, we focus on the evolution of the service provisioning platforms, from the Intelligent Networks towards the IP Multimedia Subsystem as the Next Generation Networks implementation. We stress the latest progress in the standardization activities, like common IMS and multimedia...
