JTC Broadcast
 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 European Broadcasting Union (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 European
Broadcasting Union (EBU) has active members in about
60 countries in the European broadcasting area;

BROADCAST SUMMARY
 The committee assesses the work performed within e.g.
DVB, WorldDAB and is responsible for broadcast systems
(emission-reception combination) for television, radio, data and
other services via satellite, cable and terrestrial transmitters.
CENELEC is responsible for the standardization of radio and
television receivers (TC 203, 206, 209).
 Technical activities
 Digital Video Broadcasting (DVB) and Multimedia Home Platform (MHP)
 Digital Audio Broadcasting (DAB)
 Analogue TV: Programme Delivery Control (PDC), Wide-Screen Signaling
(WSS), Electronic Programme Guide (EPG), Teletext, NICAM,
PAL/SECAM ghosting
 Analogue RADIO: DAta Radio Channel (DARC) and VHF FM Sound
Broadcasting Transmitters
 Audio/Video Coding: ETSI has published guidelines on the use of
compression formats. Amongst other things, these make more viable the
implementation of HDTV services over DVB by the inclusion of the high
performance compression in MPEG-4 part 10.
 DVB-H (Handheld DVB) is an optimisation of the terrestrial DVB-T
standard to allow broadcasting to handheld devices. The modifications
include optimisations for battery management and for the speed of
movement of the receiver

SEM02-10
Digital Video Broadcasting (DVB)
 The work of ETSI falls into two parts: system specifications
and standards to assist equipment to be placed on the
market in line with European legislation (Harmonized
Standards).
 DVB System Specifications
 The Digital Video Broadcasting Project (DVB) is an industry-led
consortium of over 260 broadcasters, manufacturers, network
operators, software developers, regulatory bodies and others
in over 35 countries committed to designing global standards
for the global delivery of digital television and data services.
Services using DVB standards are available on every continent.
 ETSI standards for DVB system specifications are developed in
the EBU/CENELEC/ETSI Joint Technical Committee Broadcast,
based on proposals from the DVB Project.

SEM02-10
DVB Return Channel by Satellite (RCS)
 EN 301 790 - Interaction channel for satellite distribution systems
 The document forms the specification for the provision of the
interaction channel for GEO satellite interactive networks with
fixed Return Channel Satellite Terminals (RCST).
 The document facilitates the use of RCSTs for individual or
collective installation in a domestic environment. It also supports
the connection of such terminals with in-house data networks.
 The revision accomplished in 2002 provides the means to
extend the applicability of the standard to regenerative satellite
systems. This revision also allows for reduction in terminal costs
without significantly impacting the performance.
 The revision accomplished in 2004 integrates the DVB-S2
standard for forward link transmission. DVB-S2 is the second
generation standard for satellite transmission, which provides
higher power and bandwidth efficiency as well as adaptive
coding and modulation.
11
SEM02-10
TR 101 790 - Guidelines for the use of EN 301 790
 The document gives guidelines for the implementation of Digital
Video Broadcasting (DVB) interaction channel for Satellite
Distribution System (also known as DVB-RCS: DVB Return
Channel via Satellite).
 The document describes the DVB-RCS specification for
geostationary satellite interactive system. It draws attention to
the technical questions that need to be answered in setting up a
DVB-RCS network and offers some guidance in finding answers
to them.
 It provides some examples of implementation details and details
about Return Channel Satellite Terminal (RCST) Implementation
guidelines.

13
SEM02-10
Terms of reference for ETSI/TC SES
 General task
 the “Home” in ETSI for Satellite Earth Stations
and Systems standardization.
 The scope can include:
 All types of satellite communication services and
applications (including mobile and broadcasting),
 All types of earth stations and earth station
equipment, especially the radio frequency
interfaces and network and/or user interfaces,
 Protocols implemented in earth stations and
satellite systems.
14
SEM02-10
Working Groups (WG)
 Working groups dealing with Harmonized standards
(R&TTE Directive):
 Earth stations on board vessels and trains (MAR ESV)
 Harmonisation (HARM)
 Working groups dealing with specific systems

Broadband Satellite Multimedia (BSM)
GEO Mobile Radio Interface (GMR)
Satellite Component of IMT 2000 (S-UMTS)
Satellite Digital Radio (SDR)
15
SEM02-10
Working Group on Geo Mobile Radio
GMR
 Geo-Mobile Radio (GMR) is a satellite-based
extension of the GSM terrestrial cellular standard
 This WG produces air interface specifications to
support mobile satellite service via geostationary
satellites at L or S bands
 GMR uses the standard GSM core network but the air
interface is modified for the satellite path
 GMR specifications include both circuit mode and
packet mode services
16
SEM02-10
Working Group S-UMTS/IMT2000
S-UMTS
 This WG is responsible for standards in the field of the
satellite component of UMTS and IMT 2000
 The Objective of ETSI activities in this field is to ensure the
seamless integration of satellite component of UMTS/IMT2000 enabling the satellite access network to directly interwork with other UMTS networks.
 It studies compatibility of services defined for the terrestrial
component with S-UMTS/IMT-2000 including, and it promotes
adoption of specific satellite services as applicable.
17
SEM02-10
Working Group Satellite Digital Radio
SDR
 SDR: Satellite broadcast to fixed and mobile
receivers, mainly for audio, with or without terrestrial
repeater network
 Objective: Creation of a Technical Specification for
the radio interface of SDR broadcast receivers
18
SEM02-10
Working Group on Broadband Satellite
Multimedia (WG-BSM)
 To produce specifications, standards and other ETSI
deliverables for broadband satellite multimedia. For
example:
 Definition of satellite system architectures supporting
broadband services
 Service requirements and descriptions for broadband
communications systems
 Definition of network architectures and interface
protocols leading to air interface standards and user
terminal specifications.
 To produce specifications that promote
interoperability between satellite networks and other
networks
 To promote adequate representation of BSM specific
issues in other technical fora

BSM Architecture
 The BSM architecture divides the air interface into 2 parts:
 Satellite independent upper layers
 Satellite dependent lower layers
 The upper layers contain a set of common BSM defined IP
interworking functions:
 Define Satellite Independent Adaptation Functions (SIAF)
 Common ways of handling Quality of Service (QoS);
Addressing; Multicast and Security etc.
 Satellite Independent Service Access Point (SI-SAP) defined
as the interface between the upper and lower layers
 An abstract functional interface
 Applicable to all satellite networks
 The lower layers contain the satellite specific functions.
 The lower layers are closely tied to the payload capability of
the satellite and hence cannot be the same in all cases.
 The SI-SAP supports multiple air interface families.

SES Work Group BSM Broadband Satellite Multimedia (ETSI
WG BSM)
 One C2P standard specifically for DVB-RCS, in close cooperation with TIA, and in liaison with DVB
 One generic C2P standard for broadband satellite multimedia
