2. Requirements from NGN/IPTV
Definition of NGN and IPTV
Definition of NGN
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.
Definition of IPTV
IPTV 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
Meeting of High-Level Experts on “Competitive Platforms for the Delivery of Digital Content”; Geneva, 21-22 June 2007
2. Requirements from NGN/IPTV
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
Requirements
IP enabled multiple managed Broadband Accesses supporting
Multimedia over Convergences (e.g. FMC, Tele-Broadcasting etc.)

4. NGN enables convergences
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”
