1 1 Ewds_jnc.ppt MULTIMEDIAviaSATELLITE Paolo De Vincenti Multimedia Programme Directorate EUTELSAT

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

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

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

5 5 Ewds_jnc.ppt 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 6 Ewds_jnc.ppt 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 7 Ewds_jnc.ppt 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 8 Ewds_jnc.ppt Application Based Analysis (1) Emerging broadband applications are based on integration of existing and new broadcasting applications and IP network-based applications

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

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

11 11 Ewds_jnc.ppt 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 12 Ewds_jnc.ppt 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 13 Ewds_jnc.ppt EUTELSAT BROADBAND DAMA SERVICES (2) DSAT 2000

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

15 15 Ewds_jnc.ppt 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. MPE* DTH CABLE SMATV DVB XDSL ISDN PSTN FRAME RELAY IP InternationalOpenStandards INTERNET BROADCASTING * Multiprotocol Encapsulation

16 16 Ewds_jnc.ppt 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 17 Ewds_jnc.ppt EMP Satellite Applications for the Internet Consumer & Corporate Direct Access Services including Push & Pull POP Backbone Smartcard** PSTN ISP DTH Household/ Company PC Backbone Backbone or Content Push Services Application Examples: ISP -caching -backbone access POP -streaming -caching Household/ Company -access/pull -push * POP: Point Of Presence ** Optional

18 18 Ewds_jnc.ppt 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 19 Ewds_jnc.ppt THE FUTURE (2) Enhanced satellite/terrestrial networks integration: integration of DAMA networks with WLL, xDSL integration of Multimedia Platforms with optical fibers.

20 20 Ewds_jnc.ppt 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 21 Ewds_jnc.ppt 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 22 Ewds_jnc.ppt 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 23 Ewds_jnc.ppt DVB-RCS (3) Terminal Prices Achievable bit rate will depend on satellite network characteristics (G/T, Gateway size, Interference environment, availability target).

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