Essential patents
IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no

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.

The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network
operators, software developers, regulatory bodies, content owners and others committed to designing global standards
for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and
economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital
television from transmission through interfacing, conditional access and interactivity for digital video, audio and data.
The consortium came together in 1993 to provide global standardisation, interoperability and future proof
specifications.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

1 Scope
The present document describes the Single Illumination System, which allows to deliver Parent Signals for direct
reception by consumer receivers and, at the same time, for a deterministic generation of daughter streams for terrestrial
retransmission. Parent Signals can be provided to the daughter site via all defined TS-based DVB means - be it satellite,
cable or terrestrial. Metadata may be provided as part of the Parent Signal(s) (called "in-band" in the present document).
Part of the metadata may also be provided "out-of-band".
A typical use case is described by the present document and is based on satellite broadcast signals on parent side - be it
DVB-S (ETSI EN 300 421 [8]), -S2 (ETSI EN 302 307-1 [9]) or -S2X signals (ETSI EN 302 307-2 [10]) - that are
addressing consumer Direct-to-Home (DTH) receivers and terrestrial transmitters on daughter side in parallel. For
terrestrial retransmission of the whole or partial content, the DTH signal(s) of MPEG-2 TS format
(ISO/IEC 13818-1 [5]) from one or several satellites can be used and services and service components can be selected
according to terrestrial broadcasters' needs. Also other non-satellite Parent Signals and out-of-band metadata feeds can
be integrated into the preparation of the terrestrial DVB-T2, ETSI EN 302 755 [2], and/or DVB-T, ETSI
EN 300 744 [3] signals on daughter site. Single Frequency Networks (SFN) operation of the terrestrial networks driven
by the Single Illumination System is enabled.
