Foreword
This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European
Broadcasting Union (EBU), Comité Européen de Normalisation ELECtrotechnique (CENELEC) and the European
Telecommunications Standards Institute (ETSI).
NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the
specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body
by including in the Memorandum of Understanding also CENELEC, which is responsible for the
standardization of radio and television receivers. The EBU is a professional association of broadcasting
organizations whose work includes the co-ordination of its members' activities in the technical, legal,
programme-making and programme-exchange domains. The EBU has active members in about
60 countries in the European broadcasting area; its headquarters is in Geneva.

Introduction
The present document informs about the possibilities of an IPTV Terminal to make use of HbbTV features.
Clause 4 of the present document contains requirements that are generic to any IPTV system when used in combination
with HbbTV. Clause 5 contains requirements that are specific to particular IPTV service discovery technologies.
Clause 6 contains requirements that are specific to particular IPTV content delivery technologies. HbbTV terminals
supporting the present document comply with the descriptions given in clause 4, and clauses of 5 and/or 6 depending on
the technologies used for service discovery and content delivery.

1 Scope
The present document describes how IPTV Terminals can make use of HbbTV features. It does not, in any way,
describe an IPTV delivery system itself. As such, technologies like fast channel change, retransmission and forward
error correction are out-of-scope. Instead it defines how several technologies may be used in combination with HbbTV
in a form that can be referenced by markets or organizations that have made choices.
Please note that the scope of the present document only includes channels that use either MPEG-2 Transport Stream or
MPEG DASH in the way defined in clause 6.2.

4 IPTV as the "broadcast"
4.1 General principles
All definitions and requirements of the Hybrid Broadcast Broadband TV specification [1] shall also apply for usage in
an IPTV service except for the changes explicitly listed in this clause. Specifically, unless explicitly stated otherwise
below:
• All relevant signalling and transport (PMT entries, AITs, DSM-CC carousels, etc.) which can be used in the
MPEG2-TS of a conventional DVB broadcast signal shall be supported in the same way for an MPEG2-TS
which is carried via IP in an IPTV system as they would be in a conventional broadcast signal.
• Selecting a broadcast channel by creating a Channel object using a DVB triplet and then selecting that channel
using the setChannel() method on the video/broadcast object shall work as specified in the OIPF DAE
specification [6] with the DVB triplet being resolved by the service discovery mechanism (for example one of
the mechanisms addressed in clause 5 of the present document).
• The requirements on starting broadcast-related applications defined in clause 6.2.2.8 of ETSI TS 102 796 [1]
are applicable to channels delivered according to the present document.
4.2 Application Lifecycle
The exceptional rules for the application lifecycle related to services without an SDT entry (in clause 6.2.2.2 of ETSI
TS 102 796 [1]) shall also apply for IPTV streams without an entry in the Service Discovery Mechanism (SD&S,
OSDT or other).
