Definition of NGN and IPTV

Definition of NGN

Definition of IPTVIPTV is defined as multimedia services such as television/video/ audio/text/graphics/data delivered over IP based networks managed to provide the required level of QoS/QoE, security, interactivity and reliability

a packet-based network able to provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies. It enables unfettered access for users to networks and to competing service providers and/or services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision of services to users.



Important Requirements from NGN and IPTV

Support broadband enough for TV, video, audio, text, graphics and Data Support Packet based transport (including IP and others) Support QoS/QoE enabled capabilities Support Security, Interactivity and Reliability in managed way Support multiple broadband with unfettered access features Support transport agnostic features for services Support generalized mobility and ubiquitous provision of services Support competition to service providers and/or services

IP enabled multiple managed Broadband Accesses supportingMultimedia over Convergences (e.g. FMC, Tele-Broadcasting etc.)

NGN; a Convergence Platform

Combination IP with Broadband accelerating intrinsic convergence

• Service convergence: Web based service provisioning

• Network convergence: IP over any broadband transport networks Advanced Mobile and Wireless technology initiate business

convergence such as Fixed-Mobile convergence Broadband Fixed, Wireless and Mobile technology boost another

business convergence, called “Multiple Play: Tele-Broadcasting”
