  11. 11. New Technologies New frequency bands Increase in the Symbol rate Variable Code and Modulation (VCM) H.264 SVC (scalable video coding) New antennas : low profile
  12. 12. 12 New Frequency Bands : BSS – Broadcasting Satellite Service 10.95 10.7 11.2 10.95 11.45 11.2 11.7 11.45 12.2 11.7 12.7 12.2 17.8 17.3 18.8 18.3 20.2 19.7 DBS/DTH Spectrum - Forward Channel (MHz) 1GHz split between two allocations High rain attenuation – primarily spot beam systems 2 degree separation DIRECTV use lower band Ka FSS upper band Ka FSS lower band Ka BSS Ku BSS Ku FSS standard Extended Ku Extended Ku Allotment Ku Allotment Ku 500MHz in development Moderate rain attenuation ~4 degree separation 500MHz used by 2nd Gen Moderate rain attenuation 4.5 - 9 degree separation 500MHz used by DTV/Echo for niche (int’l) services 2 degree separation 1GHz split in two allocations Not in use due to medium power, regulatory restrictions & terrestrial interference 2 degree separation C FSS standard 4.2 3.7 500 MHz used for Cable Low power & rain fade High reliability w/ large antennas (~3 Meter) DBS/DTH Service Providers by Spectrum
  13. 13. Ku BSS Spectrum Overview ITU developed the Ku BSS Planned frequency band for dedicated broadcast applications, it included: • Higher power & greater satellite spacing than FSS to support smaller user antennas (Direct-to-Home) – 45-60cm vs. 60-90cm • Circular polarization eliminates the need for polarization alignment of the consumer antenna, which greatly improves the ease of installation and alignment of the antenna • Dedicated & protected broadcast spectrum greatly reduces the incidence of unintended interference from an adjacent user’s uplink • Broadcast only spectrum eliminates competition for the capacity by other (two- way) applications In the U.S.A., the first generation Ku FSS DTH systems were displaced by the next generation Ku BSS systems (DIRECTV & EchoStar) due to their superior performance • The over 30 Million DTH Households currently in the US has greatly improved the economics of customer premise equipment • The Indoor Unit/Set-Top Box is the same for FSS and BSS; and a dual/triple feed antenna can accommodate Amazonas (FSS) on one feed and a BSS satellite on the other feed(s. Universal LNBs support both bands – FSS and BSS In Latin America, the Ku BSS Plan is highly fragmented because each country is assigned an allotment of fractional amount of spectrum for discrete national or even local coverage – not suited for a broad regional/ large scale system

  15. 15. O3b Constellation: • MEO orbit – fiber-like latency High Capacity: • 216 MHz Ka band transponders • Gigabit speed forward and return connectivity • Rapidly steerable 600 km spot beams • O3b Gateways with high speed direct access to video content and Internet core Benefits: • Fiber performance to locations without fiber infrastructure • Significantly lower cost than GEO bandwidth O3b Provides High Capacity and Low Latency for Video Applications
  16. 16. Event Coverage and Satellite News Gathering O3b steerable beams: • Rapidly steerable to a world hot spot • Able to capture high bandwidth HD streams • Low latency supports live real-time conversations
  17. 17. DVB-S2 : Improved Performance Forward Error Correction Eb/N0 for QEF transmission Uncoded: 14dB DVB-S/QPSK ¾: 5.2 dB DVB-S2/QPSK ¾: 2.5 dB DTH operation : cost of receivers still represents an obstacle for large number of customers.
  18. 18. DVB-S2 CCM, VCM and ACM Constant Coding & Modulation: regular scheme for broadcast Variable Coding & Modulation: services with different protections (different availability or different antenna size) Adaptive Coding & Modulation : adaptation to link budget conditions (for point to point applications)
  19. 19. Advanced use of technologies New generation of equipment : IDU
  20. 20. Unicast - Adaptive Coding and Modulation ACM brings a significant bit rate benefit: • No ACM : bit rate limited by the worst case link budget • ACM : bit rate optimized for the actual link budget Link budget variations are due to • EIRP variation in the footprint • Pointing accuracy • Rain fade • Absence or presence of interferences ACM is mandatory for Ka band in all the regions and for Ku band in heavy rain zones (LA…). Rain fade impact is marginal thanks to ACM: • 90% of the time can be considered as clear sky
  21. 21. Clear Sky HDTV – VCM Ka band in Europe QPSK 1/2 8PSK 2/3 QPSK 1/2 8PSK 2/3 SD ΔHD In a classical approach all terminals are penalized by the worst case link budget of the worst case terminal. This penalty is extreme in Ka Combination of VCM and scalable video (scalable H264) minimize this penalty: • Scalable video (Hierarchical source coding): – HD @ 8 Mbps ≅ SD @ 2 Mbps + ΔHD @ 6 Mbps • For 99% of the time of the worst case terminal, SD and ΔHD are available • For 99.9 % of the time of the worst case terminal, SD is available
  22. 22. Clear Sky SDTV – VCM Ku band in heavy rain zones QPSK 1/2 8PSK 2/3 QPSK 1/2 8PSK 2/3 LD ΔSD The scalable video principle can be used in SDTV: • For 99% of the time of the worst case terminal, LD and ΔSD are available • For 99.9 % of the time of the worst case terminal, LD is available Efficiency close to the 8PSK 2/3 This principle would minimize the penalty of the rain fade in these zones. This benefit can be used to reduce the antenna size
  23. 23. Interference Suppression New generation of equipment : ODU and IDU
  24. 24. MLNB – Principle Multi-feed phase & amplitude combination Signal from several receive combined by linear weighting The weighting is static (optimized at installation time) and transponder specific Practical effect: notch on the interferers • example: +2.0deg and - 2.0deg; 3 feeds
  25. 25. Satellite DTH Reception Evolution Summary Installation Reflector In-home signal distribution LNB Set-Top-Box • Multi-band, „wide-angle“, interference cancellation, interactivity • Integrating decoding & routing • Supraconductivity to reduce the noise for some applications • Integration in in-home LAN (e.g. as a satellite multicast router) • PLC, RF, HomePlug, …from the STB or the LNB • Trend to smaller reflectors • Flat antennas • Phased arrays • Integrated e.g. in windows (ERA) • Simple pointing devices • Auto-fine pointing LNB (e.g. For Ka) • Autopointing antennas e.g. phased array • Generic uPnP / DLNA (hybrid) IP device, redistributing multimedia and datacasting signal on the home LAN • Possible integration in TV set or with the home storage unit • Low cost units for emerging DTH markets; DVB-S2; MPEG-4 Integrated in the home’s IP network, more user-friendly and less intrusive (>< coax, large dish) Some innovations are risky for premium positions
