IPTV Introduction

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 quality of service
and experience, security, interactivity and
reliability.

IPTV Introduction

The interface to the access network is
generally common, but there are
significant variations on how the other
components are structured and behave.

In a setting where even subtle variations
on protocols or data formats can be a
barrier to interoperability.

European Telecommunications Standards
Institute Telecommunications and Internet
converged Services and Protocols for
Advanced Networking(ETSI TISPAN)

DVB

DVB released DVB-IPTV 1.4 handbook in
2008.

The goal of the handbook is to specify
technologies on the interface between an
IP network and a Home Network End
Device (HNED).

ETSI TISPAN

ETSI TISPAN was chartered in 2004 to
standardize Fixed NGN, working alongside
3GPP which concentrated on mobile NGN.
 TISPAN
has published NGN R2 in June
2008. There are two variants of IPTV in
TISPAN R2 (and also in R3): Dedicated
IPTV and IMS-Based IPTV.

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.”
20
ITU-T IPTV Focus Group and GSI

IPTV Domains: Four IPTV domains are
identified including content provider,
service provider, network provider and
end user.
21
ITU-T IPTV Focus Group and GSI

IPTV Architectural Approaches: Three
IPTV architecture approaches are
identified that enable service providers to
deliver IPTV services:
 Non-NGN IPTV functional architecture (NonNGN IPTV),
 NGN-based non-IMS IPTV functional
architecture (NGN-Non-IMS IPTV),
 NGN IMS-based IPTV functional architecture
(NGN-IMS-IPTV).
22
ITU-T IPTV Focus Group and GSI

IPTV Functional Architecture: Functions
and functional blocks described in this
clause are common to all architectural
approaches.
23
ITU-T IPTV Focus Group and GSI
24
OIPF

The objective to specify a common and
open end-to-end solution for supplying a
variety of IPTV and internet multimedia
services.

Conclusion

The pursuit of a single IPTV standard may have
failed.

With so many available standards, vendors and
operators will need to make hard choices.
