  1. MULTIMEDIA via SATELLITE Paolo De Vincenti Multimedia Programme Directorate EUTELSAT

  2. SATELLITE: Why?? (1) • BANDWIDTH Satellite networks offer • Broadband Links • Bandwidth independency from the number of users for Broadcast and Multicast transmissions

  3. SATELLITE: Why?? (2) • COVERAGE Satellite coverages enable the international and intercontinental extension of the networks overcoming • geological constraints • poor terrestrial infrastructures

  4. SATELLITE: Why?? (3) • RELIABILITY • EXPANDABILITY • FLEXIBILITY

  5. SATELLITE SERVICES EVOLUTION (1) • FROM • CENTRALISED INSTALLATIONS , • LARGE DIMENSIONS (Dant from 13 m to 3.7 m), • HIGH POWER (Pout from 1500 W to 150 W) • HIGH INVESTMENT AND OPERATION COSTS • TO • DISTRIBUTED TERMINALS, • SMALL DIMENSIONS (Dant from 3.7 m to 60 cm), • REDUCED POWER (Pout from 150 W to 1 W) • REDUCED INVESTMENT AND OPERATION COSTS

  6. SATELLITE SERVICES EVOLUTION (2) SATELLITE PARTECIPATES IN THE GENERAL EVOLUTION OF TECHNOLOGY: - WIDESPREAD DIFFUSION OF THE INSTRUMENTS OF INFORMATION TECHNOLOGY - WIDESPREAD ACCESS TO AN INCREASING NUMBER OF INFORMATION - DIFFUSION OF THE CAPABILITY OF CREATING AND TRANSMITTING CONTENTS

  7. Market Based Analysis Market segmentation between: • consumer profile (provision of services to the residential user) • professional profile (provision of services to the business user): • SOHO • corporates • banks • institutions (Schools, Public Administration, Hospitals)

  8. Application Based Analysis (1) Emerging broadband applications are based on integration of existing and new broadcasting applications and IP network-based applications

  9. Application Based Analysis (2) CONSUMER PROFILE • Interactive Television • Internet via satellite • e-commerce • e-banking • leasure

  10. Application Based Analysis (3) PROFESSIONAL PROFILE • Software and Data distribution • Business TV • Internet via Satellite • Videoconference • Distance Learning • Telemedecine • Monitoring and Control

  11. PROFESSIONAL NETWORKS EUTELSAT BROADBAND DAMA SERVICES • Multimedia Mesh Networks • Based on Bi-directional Balanced Terminals (antenna diameter D from 1.2 m to 2.4 m, SSPA output from 2 W to 25 W) • Demand Assignment of Satellite capacity to each terminal means • Reduced Space segment costs • Optimised transponders use

  12. EUTELSAT BROADBAND DAMA SERVICES (1) • Adaptive transmission bit rate (from 64 KB/sec to 4 Mb/sec) • Access Scheme: Multifrequency TDMA • Network reconfigurability in real-time • IP, Ethernet, ATM, Frame Relay, ISDN interfaces

  13. EUTELSAT BROADBAND DAMA SERVICES (2) DSAT 2000

  14. Satellite IP Broadcast (1) Internet households in Europe (in millions) Source: Morgan Stanley Dean Witter “The European Internet Report, July 1999” Eutelsat analysis

  15. INTERNET BROADCASTING International Open Standards IP DVB XDSL DTH PSTN CABLE MPE* SMATV ISDN FRAME RELAY Satellite IP Broadcast (2) Based on the encapsulation of IP packets into DVB Transport Stream. The DVB Stream is received via a DTH antenna and IP packets are de-encapsulated by an interface card. * Multiprotocol Encapsulation

  16. Satellite IP Broadcast (3) EUTELSAT Multimedia Platform (EMP) Concept • A platform providing a variety of multimedia services • Platforms built following a standard EUTELSAT specification • Utilization of low cost receive equipment • Utilization of terrestrial return line • Utilization of coverages and orbital positions particularly suitable for the service and market addressed (7°&10°East, 8°West)

  17. DTH Household/ Company ISP Backbone POP PC Backbone PSTN Smartcard** Backbone orContent PushServices Consumer & CorporateDirect Access Servicesincluding Push & Pull EMP Satellite Applications for the Internet • Application • Examples: • ISP • -caching • -backbone • access • POP • -streaming • -caching • Household/ • Company • -access/pull • -push * POP: Point Of Presence ** Optional

  18. THE FUTURE (1) • Enhance the integration of satellite networks with terrestrial ones • Increase the Frequency Bandwidth available on satellites • Decrease the cost of terminals • to increase the use of bi-directional networks, • to make return channel via satellite accessible also to consumers and SOHO

  19. THE FUTURE (2) • Enhanced satellite/terrestrial networks integration: • integration of DAMA networks with WLL, xDSL • integration of Multimedia Platforms with optical fibers.

  20. THE FUTURE (3) • Introduction of Ka band • Increase of satellite G/T through the use of multiple spot beam coverages to reduce the size and power of the terminals • Improvement of On-Board Processing (OBP) techniques for on-board cross connection between spot beams • Standardization of systems to ensure interoperability and large volume production of terminals

  21. DVB-RCS (1) Development Program Objective • to design and develop bi-directional satellite terminals meeting the DVB-RCS standard and therefore ensuring interoperability between terminals and HUBs from different manufacturers. This way • to ensure large volume production for terminals and therefore • to decrease the price of terminals

  22. DVB-RCS (2) System Characteristics • Multifrequency TDMA Access Scheme • MPEG Profile • Turbo Coding • Capacity request signaling • Standardized ODU/IDU Interface • System flexibility to work in Ku-band and/or Ka-band

  23. DVB-RCS (3) Terminal Prices Achievable bit rate will depend on satellite network characteristics (G/T, Gateway size, Interference environment, availability target).

  24. DVB-RCS (4) Feeders & Gateways MF-TDMA 128-2000 Kbps DVB-S 38 Mbps typically =2.4m-9m NCC THE INTERNET RCSTs =60cm-120cm
