Beyond DVB-S2: Next-Gen Satellite Transmission Standards


Published on

The importance of standards is not to be underestimated, they protect end-users from vendor lock-in and provide freedom of choice, which was the aim of the DVB-S (Digital Video Broadcast - Satellite) standard.

At Newtec we strive to increase the efficiency of the DVB standard. That is why we are contributing to a more efficient DVB-S2 standard, to establish an evolution that further optimizes satellite capacity usage.

This presentation focuses on two specific aspects of this strive for improvement:

- How to reduce costs for transmissions (focusing in this case on Clean Channel Technology)
- Addressing Satellite Interference (RFI)

Beyond DVB-S2: Next-Gen Satellite Transmission Standards

  1. 1. May 26th 2012
  2. 2. Drivers for change: Beyond DVB-S2 Moore’s law: Technology can now do more Cost reductions for transmission Needs to address RF Inteference2
  3. 3. Newtec Contributes to even better Standards Standards are important The DVB (Digital Video Broadcast) standard protects end-users from vendor lock-in and provides freedom of choice. Evolution is good for our industry DVB evolutions like DVB-S to DVB-S2 provided 20-30% OPEX reduction for broadcasters. Newtec contributes to a more efficient DVB-S2 Newtec contributes to DVB to establish an evolution that further optimizes satellite capacity usage Newtec actively supports standardization of Carrier ID (CID)3

  9. 9. …the Stats!Data supplied by Intelsat… 96% (of 47%) Unintentional 4% (of 47%) Pirates/Jamming Note: In MENA, ‘deliberate’ is considerably higher (ask Al Jazeera!)
  10. 10. SES Experience with RFI…
  11. 11. Different Types of Interference… Different Responses Needed…11
  12. 12. Ready to combat Carrier Interference ? Radio Frequency Interference (RFI) ... high on the agenda of satellite operators! • RFI is the largest single issue that impacts QoS for satellite operators and their customers • Sources of RFI are operational mistakes in modulator configuration, wrong polarization, carrier saturation, pointing to wrong satellite, failing equipement ... or intended interference • In addition to current RFI counter measures such as – Training operational staff on best practices – Automated terminal configuration (e.g. Newtec´s MENOS) – Satellite pointing technology such as Newtec´s Point and Play® there is a need to embed a carrier identifier (CID) into the carrier itself to allow a robust yet quick pinpointing of the source of the interference12
  13. 13. Ready to combat Carrier Interference ? …Newtec is ! M6100 Carrier ID setup How Does it work ? • An ID is injected by the modulator into the carrier (CID) containing : • Fixed identification of the source • Vendor brand, MAC, serial n°, etc ... • User configurable data • GPS coordinates, carrier name, contact, etc... • In case of RFI, the satellite operator can read this CID and can therefore quickly identify the source and contact information of the RFI originator, using a shared repository of CID´s • Initially, a NIT version of carrier ID will be used by operators • It is anticipated that a DVB standard will likely be available end of 2012 with a more robust RF CID standard13
