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.

1 Scope ®
The present document specifies a platform, based on the existing HbbTV specification ETSI TS 102 796 [1], that
supports the signalling, transport and presentation of an operator application. The operator application is able to replace
some of the terminal's user interface. The extent to which the terminal user interface is replaced by an operator
application depends on the type of the operator application and the business models of the operator and manufacturer.
The present document assumes the presence of an agreement between an operator and the device manufacturer.
Operator applications will not run in the absence of such an agreement. Topics that could or need to be covered by such
a bilateral agreement are listed in annex D.
The present document makes use of functionalities described in ETSI TS 102 796 [1] which is describing a platform for
signalling, transport, and presentation of enhanced and interactive applications intended for running on hybrid terminals
that include both a DVB compliant broadcast connection and a broadband connection to the Internet. The usage of a
hybrid terminal for IPTV delivered audio-visual content is described in "IP-delivered Broadcast Channels and Related
Signalling of HbbTV Applications" [i.4].
