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

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. 

11
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.

12
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.

Standardization in the Satellite field
The role of ETSI / TC-SES

14
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.

15
Working Groups (WG)

• Working groups dealing with Harmonized standards
  (RTTE 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)

16
Working Group on Geo Mobile RadioGMR

• 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

17
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/IMT-2000 enabling the satellite
  access network to directly inter-work 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.

18
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

19
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.

22
BSM air interface families

• Transparent Satellite Star A (TSS-A)
• TS 102 352 TS 102 402
• DVB-S/DVB-RCS profile for transparent satellites

• TS 102 429-x (4 parts)
• DVB-S/DVB-RCS family for regenerative satellites

23
Preparation of the C2P standard(Connection
Control Protocol)

• Mesh networks requires enhancement of the control
  plane of the DVB-RCS systems
• The task to develop two C2P-standards is taken on
  by ETSI TC SES Work Group BSM Broadband Satellite
  Multimedia (ETSI WG BSM)
• One C2P standard specifically for DVB-RCS, in
  close co-operation with TIA, and in liaison with
  DVB
• One generic C2P standard for broadband satellite
  multimedia systems
