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) More info: visit www.newtec.eu

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.

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 interference

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 standard
