FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The IEC 62766 series is based on a series of specifications that was originally developed by
the OPEN IPTV FORUM (OIPF). They specify the user-to-network interface (UNI) for
consumer terminals to access IPTV and open internet multimedia services over managed or
non-managed networks as defined by OIPF.

4 Metadata content
4.1 General
The content metadata specified in the present standard are based on two ETSI specifications:
• Service discovery and selection (SD&S)
SD&S metadata are a set of data related to the service discovery and selection (SD&S)
mechanism as defined in ETSI TS 102 034. These metadata allow the OITF to retrieve
information to select linear TV services (i.e. multicast address, channel name, package,
etc.), BCG services (for linear TV or CoD) or other DVB services. For FCC/RET services,
the appropriate SD&S records are defined in Annex I of ETSI TS 102 034:2014.

IEC 62766-3:2016  IEC 2016 − 11 −
• Broadband content guide (BCG)
The BCG is a set of data related to the description of linear TV events and services,
and/or CoD content as defined by ETSI TS 102 539.
This clause defines extensions to the SD&S and BCG schemas and the AV classification
schemes. Refer to the ETSI TS 102 034 and ETSI TS 102 539 specifications for the base
schemas.
4.2 Schema extension and validation
4.2.1 General
The metadata is in the form of an instance document which is validated against a schema
defined in the present document. The XML schema is obtained by extending the SD&S
schema defined in ETSI TS 102 034 and the BCG schema defined in ETSI TS 102 539.
4.2.2 Metadata extensibility
This document provides schema descriptions of those elements and attributes that are
extended from the original schema defined in ETSI TS 102 034 for SD&S, or ETSI TS 102 539
for BCG. The extension rule adopted in this standard follows the forward compatibility
constraints specified in order to be able to extend the BCG schema in ETSI TS 102 822-3-2.
4.2.3 Metadata validation
No specific XSD validation tool is mentioned in ETSI TS 102 034 for SD&S or in ETSI TS 102
539 for BCG. Content that is purported to conform to the extension specified in this document
shall pass a validation test using any widely-accepted XSD validation engine. In cases where
the narrative description of this standard conflicts with the extended schema, the narrative will
be considered authoritative. A companion schema (.xsd) document associated with the
present document provides the consolidated XML schema definition of SD&S and BCG
metadata extended as defined in the present document.
4.3 SD&S extensions
4.3.1 General
This subclause describes the extensions to the SD&S schema described in ETSI TS 102 034
in conjunction with the generic application signalling defined in ETSI TS 102 809. SD&S
records provide an XML-based description of service providers and their services. They
enable OITFs to discover and select appropriate services. In addition to ETSI TS 102 809,
extensions are defined in order to provide a means to signal web-based applications from
within SD&S records. Extensions are provided also for
• bandwidth renegotiation,
• purchasing a broadcast service,
• indicating container format.
For FCC/RET, no extensions are required, but the definition of one SD&S element is extended
in order to indicate to the OITF to use the cookie signalling method for FCC/RET services,
without breaking the interpretation of this SD&S element for non-OIPF deployments.
All schema extensions are described in Annex B. For details of the original SD&S schema,
see ETSI TS 102 034.
− 12 − IEC 62766-3:2016  IEC 2016
4.3.2 Service provider discovery extensions
4.3.2.1 General
Service provider discovery information contains information about service providers including
references to the service offerings as well as any OIPF-specific services they may provide
(e.g. emergency notification service). Further details of the service provider XML schema can
be found in 5.2.13.7 of ETSI TS 102 034:2014.
The service provider type is extended by the present standard to signal the access
information for the emergency notification service, see Figure 1.
The schema for the extension is provided in Clause B.3.
IEC
Figure 1 – Outline of service provider record updates
4.3.2.2 Emergency notification service
EmergencyNotificationService contains SDP-based session description that the terminal
needs in order to receive an emergency notification message. Two methods are used to carry
session information.
• Inline: where the SDP file is inlined in the service provider XML document as element
content. This is useful for situations where the contents of the SDP file are fixed.
• Out of band: where the SDP file is delivered independently of the service provider XML
document. This is useful for situations where the contents of the SDP file are not
necessarily fixed. In this case, the SDP file can be delivered via unicast or multicast. For
unicast, a URL is provided; for multicast, an SDPStream together with an SDPURI are
provided.
The schema for the extension is provided in Clause B.4. Table 1 provides a description of the
parameters and Figure 2 depicts an emergency notification structure.

4.3.3 Service discovery extensions
4.3.3.1 General
Service discovery records provide descriptive information about and access details to the
services (e.g. service name, service URL, etc.) offered by a service provider, for example,
linear TV broadcasts or BCG(s).
Three types of extension are defined by this document:
• bandwidth renegotiation;
• purchasing broadcast services;
• indicating container format.
4.3.3.2 Bandwidth renegotiation
The MaxBitrate element in the IPService record of SD&S (ETSI TS 102 034) shall be provided
in case of scheduled content services with SIP session management provided in managed
networks relying on IMS. It is used during session initiation or session modification to ensure
that the necessary bandwidth is available in the network. Table 2 shows this extension of the
Broadcast Discovery record.

The IPService record of SD&S ETSI TS 102 034 is extended for scheduled content services
with SIP session management with an optional TimeToRenegotiate element that, when
present, is used to determine when down-sizing of the reserved bandwidth for the content
session is performed. This extension is shown in Table 3.
See Clause B.7 for the IPServiceType schema extension.

TimeToRenegotiate This element provides the duration in seconds to be O
used in conjunction with MaxBitrate to determine
when renegotiation of network bandwidth shall
occur.
a
M = Mandatory
O = Optional
Each service is represented by an IPService structure in the Broadcast Discovery record.
When the service is changed, typically through a user-initiated channel change request, the
TimeToRenegotiate value will be used for scheduled content services with SIP session
management in conjunction with the MaxBitrate to determine how bandwidth re-negotiation
will be performed.
At every channel change, if there is a pending timeout for session modification due to a
previous service change it is cancelled. The OITF may initiate a new session modification as
described below.
The TimeToRenegotiate element should only be provided in an IPService structure
representing a scheduled content service with SIP session management. When the
TimeToRenegotiate element is provided with the IPService record then
• if the MaxBitrate of the new service is greater than the reserved bandwidth, network
bandwidth reservation using the MaxBitrate of the new service shall occur immediately, to
ensure sufficient bandwidth is made available for the new service;
• if the MaxBitrate of the new service is equal to the reserved bandwidth, network bandwidth
reservation procedures shall not be performed, as sufficient bandwidth is already available
for the new service;
IEC 62766-3:2016  IEC 2016 − 15 −
• if the MaxBitrate of the new service is less than the reserved bandwidth, network
bandwidth reservation using the MaxBitrate of the new service shall occur after the period
(in seconds) provided by the TimeToRenegotiate element of the new service.
4.3.3.3 Purchasing broadcast services
The IPService record of SD&S ETSI TS 102 034 is extended to include an optional
PurchaseItem element, as shown in Table 4. The PurchaseItem element allows conditions to
be placed on the availability of purchased content.
See Clause B.7 for the IPServiceType schema extension.

4.3.3.4 Container format indication
The IPService record of SD&S ETSI TS 102 034 is extended to include an optional FileFormat
element as defined in “AVattributesType” defined in clause 6.3.5 of TV-Anytime specification
ETSI TS 102 822-3-1. This element provides a means to indicate file format. This extension is
shown in Table 5.
See Clause B.7 for the IPServiceType schema extension.

The FileFormat element shall be provided in case of scheduled content services with SIP
session management provided in networks relying on IMS, to signal the use of SIP session
management.
4.3.3.5 FCC/RET attribute definition
The SD&S FCC/RET attributes are defined in Annex I of ETSI TS 102 034:2014. The relevant
extract of the broadcast discovery record is shown in Table 6.
