The Op n IPTV Forum (OIPF) IPTV solution provides sp cification for an en -to-en

platf orm for the de loyment of IPTV services Fig re 1 s ows a high-level logical view of the

The Op n IPTV Forum has develo ed an en -to-en solution to al ow an con umer en

p rsonal sed IPTV services either in a managed or a non-managed network

To that en , the Op n IPTV Forum foc ses on stan ardisin the u er to-network inter ace

(UNI) b th for a managed an a non-managed network, as de icted in Fig re 1

Figure 1 – Ope IPTV Forum s ope

Throu hout the sp cif i ation , the terms “o en Internet an “u managed network” are u ed

interc an e bly to refer to the a i ty to ac es an service provider u in an ac es

network provider without an q al ty of service g arante s

Managed network IPTV services are provided with QoS g arante s, for example within a

triple-play wal ed garden

Op n Internet IPTV services are ac es ed via the Internet, without QoS g arante s, for

example via a p rtal

In b th cases, IPTV services are ac es ed via a service platform that provides s p ortin

f aci ties for multiple service providers

Third-p rty content providers s p ly media as ets that are del vered within the IPTV services

Managed network IPTV services are provided f rom within an o erator’s core network,

Op n Internet IPTV services are ac es ed via an in e en ently o erated ac es network,

with or without QoS g arante s Op n Internet IPTV services may b ac es ed via a service

platform (e.g a p rtal) that provides s p ortin faci ties for multiple service providers

Figure 2 – IPTV solution s ope

The doc ment provides an en -to-en solution that can provide an of the fol owin IPTV

services:

• s hed led content services (lne r TV), p s ibly h brid (combinin the u age of IPTV an

• media formats for voice an A/V commu ication services;

• h brid (bro d ast-bro db n ) a plcation s p ort

These IPTV services can b provided generaly in b th the managed network an o en

internet modes of o eration, but there may b dif feren es in how e c service is provided

An ex B provides the def i ition of the relevant f un tional entities an the ref eren e p ints

b twe n them, whic are sp cif ied normatively in the other p rts of the IEC 6 7 6 series

Comp red with the ITU-T IPTV arc itecture, as sp cified in ITU-T Recommen ation Y.1910

[3] the OIPF Fu ctional Arc itecture [1] a pl es dif ferent terminolog for f un tional entities

an referen e p ints, but there is a cle r logical ma pin b twe n the two arc itectures,

hen e they are not in contradiction in any resp ct

The OIPF IPTV terminal fu ction (OITF), as des rib d a ove, is a logical fu ctional entity that

can b implemented in an kin of a pro riate terminal device The OITF implements the UNI

sp cified in the present doc ment but there is no pres ription of the actual terminal device

This is in contrast, to a certain extent, to the a pro c for ITU-T terminal devices introd ced

in ITU-T Recommen ation H.7 0 [4] but the two a pro c es are not in contradiction

4.2 Me ia formats

IEC 6 7 6-2-1 sp cif ies the complete set of ado ted media f ormats, in lu in au io, vide

an s stems layers, also an i ary content s c as s btitles an resources u ed by other p rts

of the solution, namely gra hic an au io cl p f ormats f or the interactive a plcation

en ironments

Sup ort for H.2 4/AVC vide [5] an HE-AAC au io for content del very services is man atory,

but further o tional codec are in lu ed in order to cater for sp cific regional req irements

an migration f om legac de loyments

Vide f ormats f or A/V content services are sp cified for HD an SD f ormats Sub-picture

vide profi es for PiP an other services are also sp cified

Sy tems layers are sp cified b sed on MPEG-2 s stems ( ran p rt stre m) an the MP4 f ile

f ormat, b th of whic are man atory to b s p orted f or u protected content in the OITF For

protected f iles, thre variants are sp cified: OMA DCF, OMA PDCF an Marl n IPMP

Ad itional f eatures related to media formats are:

• cle n au io fu ction, ref er in to the solution sp cif ied by DVB;

• media formats f or voice an A/V commu ication services;

• media f ormats f or A/V content services via mo i e network to mo i e terminals;

• sig al n f or the del very of DAE a pl cation in-b n within MPEG-2 TS [6]

4.3 Adaptiv stre ming

IEC 6 7 6-2-2 is the sp cif i ation for HTTP ada tive stre min There are two method

sp cified for ena l n ada tive bit- ate stre min with IPTV services

The first, an pref er ed method, is b sed on MPEG DASH [7] where y OIPF-sp cific

intero era i ty p ints are defined f or DASH u age with MPEG-2 TS an ISOBMFF [8]

container content

The secon is the OIPF HTTP ada tive stre min (HAS) f ormat, whic is b sed on 3GPP

Rele se 9 PSS An exten ion is sp cified in order to ac ommodate the MPEG-2 TS s stems

layer as wel as MP4 fi e f ormat HAS also provides ef ficient management an del very of

comp nent media stre ms (e.g alternative au io lan uages) with ada tively stre med

content

4.4 Conte t meta ata

IEC 62 6 -3 sp cifies al asp cts of content metadata, in lu in service provider information

an metadata del very

Two levels of service an content dis overy an selection are def i ed, mir orin the DVB

sp cification , stan ardised by ETSI f or service dis overy an selection (SD&S) [9] an

bro db n content g ide (BCG) [10]

Where s DVB SD&S f oresees the del very of metadata within XML doc ments, the IPTV

solution also ena les service dis overy via CE-HTML [1 ] content as p rt of an interactive

a plcation hosted by the declarative a pl cation en ironment (DAE), des rib d b low

Provision is also made for metadata to b del vered within the content, i.e the MPEG-2

tran p rt stre m, namely as DVB service information, EIT present f olowin , without

ac omp n in SDT inf ormation This method en ures that at le st a minimum of metadata is

avai a le to the OITF in every circ mstan e, e.g when u icast retrieval of the metadata mig t

b overlo ded at the server It is also very con enient f or q ic retrieval e.g when the OITF is

za pin throug l ne r TV services

IEC 6 7 6-3 sp cifies some exten ion to DVB SD&S Exten ion are defined for the

f ol owin purp ses: DAE a pl cation sig al n , b n width renegotiation, content an service

protection control information, an f ile format in ication

Several exten ion are also sp cified for BCG, namely: tran p rt protocol indication, content

protection information, an content f ormat information, comprisin au io, vide , f ile format,

tran p rt protocol, an p rental g idan e information

Metadata del very is p rf ormed as sp cif ied in DVB SD&S an BCG, i.e u in DVB SD&S

As sp cified by DVB, BCG data can b del vered in containers via u icast or multicast,

in lu in updates via TVA f agments The OITF may also implement the SOAP q ery

mec anism to selectively retrieve BCG data

4.5 Protocols

IEC 6 7 6-4-1 brin s together the sp cification of the complete set of protocols for the IPTV

solution, coverin the referen e p int interf aces defined in the OIPF Arc itecture [1] These

referen e p ints are clas if ied as:

• the UNI inter aces, b twe n the network or service provider domain and the con umer

domain;

• the HNI interaces, b twe n the f un tional entities in the con umer network domain;

• the NPI inter aces, b twe n the f un tional entities in the network an service provider

domain ; an

• interf aces to external s stems, e.g the DLNA home network [12]

Fig re 3 s ows the fu ction in ide e c of the residential network f un tional entities an the

set of UNI an HNI ref eren e p ints that interace to them

Note that the a pl cation gateway (AG) f un tional entity is o tional, so that in its a sen e,

OITFs commu icate with services via the HNI-INI set of interf aces directly This mode is also

sti p s ible when an AG is de loyed Note also that HNI-AGG an HNI-AGI interaces are

not specified
