To provide high quality of multimedia service in mobile environment, mobile IPTV service technology that enables higher reliability of transmission quality and multimedia service to many subscribers has been developed. One of the important technologies for mobile IPTV is to mitigate interference. This can be done by the configuration of MBS zone. 3GPP/LTE and Mobile WiMAX support MBS technology to...
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 proposes a functional architecture on MS (Mobile Station) for MS. The proposed MS has several management modules and binding tables about authentication and session to provide seamless multimedia services. The binding table about authentication and session to provide seamless multimedia services. The binding table is managed in the MSS(Media Streaming Server) as well as HG(Home Gateway)...
The following topics are dealt with: advanced communication technology; wireless communication technology; mobile communication; RFID technology; USN technology; home network technology; wireless sensor network; optical networking technology; distributed computing; game technology; multimedia technology; information security technology; next generation network technology; network management; network...
IP multimedia Subsystem (IMS) is one the most promising architectures for IP Television (IPTV). It proposes a common control plane achieving a certain service convergence and guaranteeing Quality of Service (QoS). The QoS issue is a major research challenge in NextTV4all, an ambitious project of the competitive pole Images&Réseaux in France that proposes a package of innovative services enriching...
The Third Generation Partnership Project(3GPP) forum [1] has specified IMS (Internet Protocol Multimedia Subsystem) which provides resource, admission and charging control [2] for multimedia services. The OMA (The Open Mobile Alliance) forum [3] has specified BCAST (Mobile Broadcast Services) [4] which is network agnostic service enabler for mobile broadcast service. Up to now, IMS and BCAST are separated...
Mobile WiMAX access network is being developed to support various multimedia services such as mobile Internet Protocol Television (IPTV), mobile Video-on-Demand (VoD), and mobile internet services. This mobile network is a shared radio medium which utilizes a point-to-multipoint method, where one base station (BS) can be connected to many mobile stations (MS). That is to say that a mobile IPTV viewer...
As the number of requiring multimedia streaming and broadcasting such as IPTV through wireless access network, to provide efficient mobility in access network can be important issue. Proxy Mobile Internet Protocol (PMIP) is aimed for network side mobility support without Mobile Node side processing. In this paper, we extended our previous work by developing mathematical analysis which contains 2 state...
As the fast growth in the development of the related technologies, IEEE 802.11-based wireless mesh networks (WMNs) will be widely deployed as the access networks in community or campus environments. In this kind of WMNs, the playback of multicast streaming video (such as IPTV) could be discontinued due to the handoff process of the mobile stations. In this paper, practical system architecture for...
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.
In this paper, we propose a new hybrid broadcasting method for bandwidth-restricted clients. The proposed method is called Pagoda-Extended Fibonacci Hybrid Broadcasting (PEFHB) which incorporated Pagoda Broadcasting and Fibonacci Broadcasting. By combining two methods, we reduced the maximum wait time of clients comparing to conventional NVoD methods. Our simulation results showed that PEFHB significantly...
For converged technology both broadcasting and communication, currently mobile IPTV is focused on portable broadcasting system with users' feedback. To implement mobile IPTV based on mobile communication, the MIMO technique is necessary due to increasing capacity and applying different modulation ratio. In this paper, we proposed decision vector. The decision vector improves system performance by...
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,...
Mobile access networks are being developed to support various multimedia services such as IPTV (Internet protocol television), VoD (video on demand), and high speed Internet services. Especially, these networks are a point-to-multipoint method in which one MAG (mobile access gateway) and many MNs (mobile node) are connected. In other words, if a mobile multimedia viewer is joining a specific multicast...
Television (TV) is getting more personal. It went from a passive broadcast medium without any form of personalization or user identification, to subscription TV, interactive TV and now to IPTV, featuring an integrated return channel. IMS-based IPTV is a good example of a personalised IPTV architecture, featuring advanced identity management. This article studies a next step in the personalization...
In this paper, we analyze the efficiency of resource occupied by QoS management messages in the converged wireless networks. Handover blocking may be generated by radio resource limitation when a number of QoS management messages are transferred between nodes simultaneously. So, the analysis of bandwidth occupied by QoS management messages is required to prepare the solution for handover blocking...
Future Internet requires a service provision that guarantees the adequate control of user related profiles and information. Current service enabler architectures provide attracting tool boxes to compose and provide advanced services in converged environments.
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,...
