different types of networks ranging from satellite links to dedicated video

circuits and microwave links.

synchronization between network components

to the IPTV end user.

► IPTVCDs

An abbreviation for IPTV consumer device, an IPTVCD is defined

as a hardware device that typically terminates an IPTV connection

Examples of IPTVCDs include media center PCs, game consoles,

residential gateways, and IP digital set

IMS

► Reasons for using an IMS core:

Core service network that is

independent of access

technology

Same application and service is

available from any access

method or device

Ability to migrate and deploy

across fixed and mobile users

Standards allow scalable

deployment of new services

Evolution to combined services

for enhanced user experience

(presence, messaging, address

book)

Security is built in — identity

management, authentication,

authorization, and service

access

Centralized user profiles shared between applications Architecture designed for scalability and redundancy Common solution to achieve quality of service

Flexible charging for multimedia and combined services

► For interactive features like voting by short message service (SMS) for a watched IPTV program, IMS will allow service providers to unify billing as part of a triple play bundled service.

IPTV Standards

► DVB OVER IP NETWORKS

Digital Video Broadcasting — Internet Protocol Infrastructure (DVB-IPI) [5]

provides a set of technical specifications that cover the delivery of DVB

MPEG-2-based services over bidirectional IP networks, including

specifications of the transport encapsulation of MPEG-2 services over IP

and the protocols to access such services Another important issue is the

specification of the service discovery and selection (SDS) mechanism for

DVB MPEG-2- based audio/video (A/V) services over bidirectional IP

networks to define the service discovery information, its data format, and

the protocols.

► ITU-T FG IPTV

ITU-T Focus Group IPTV [6] evaluates IPTV regarding various issues such

as services, architecture, IPTV middleware, security, and so on It is

expected that IPTV will be included in the next ITU-T NGN

recommendations

► ETSI TISPAN IPTV

In TISPAN NGN R2, several specifications address IPTV regarding service

requirements and architectures with a non-IMS IPTV subsystem, as well as

IMS-based IPTV

IPTV Standards

► ATIS IPTV INTEROPERABILITY FORUM

The Alliance for Telecommunications Industry Solutions (ATIS) initiated the IPTV

Interoperability Forum (IIF) that develops standards to enable the

interoperability, interconnection, and implementation of IPTV systems and services,

including video-on-demand and interactive TV services The ATIS analyzes within

the IIF initiative several important aspects of IPTV and defines the IPTV logical

domains, IPTV reference architectures (IMS- and non-IMS-based IPTV and their

coexistence) [10], content delivery concepts with quality of experience, digital rights

management (DRM) requirements, and interoperability standards, as well as testing

requirements for the components, reliability, and robustness of service components

► 3GPP MBMS

3GPP specifies multimedia multicast/broadcast service (MBMS) specifications

[11] mainly to define an efficient way to deliver and control multicast and broadcast

services over 3G networks MBMSs are limited at this moment to mobile TV channel

bandwidth, which is usually up to 200 kb/s The advantage of MBMS in comparison

with DVB-handheld (DVB-H) is that the same IP-based common infrastructure is

used as for 3G data services.

► OMA BCAST

The Open Mobile Alliance (OMA) introduces the concept of the mobile broadcast

services enabler to address functional issues that are generic enough to be common

to many broadcast services and that can be defined and implemented in a

bearer-independent way.
