Carrier identification counter-measures critical for combating satellite interference

Interference of satellite carriers is a growing problem in the industry for users of satellite transmissions. There is an industry consensus that counter-measures should utilise the addition of carrier identification to enable the quick location and correction of misconfigured or unauthorised carriers.

DVB has accepted the topic of Carrier ID as a work item and that as a first step the commercial and market requirements will be captured within the Commercial Module and its relevant sub-group DVB-CM BSS. Once approved by the Commercial Module and Steering Board, such requirements will be passed to the Technical Module of DVB to review the various technical options from which a solution will be defined and selected that best meets the Commercial Requirements.

For the transmission of transport stream live video over satellite, the addition of Carrier ID within the transport stream NIT table is considered one potential intermediate solution.

Serge Van Herck, CEO of Newtec said: “Whilst an intermediate solution is necessary we need to look to the longer term. We welcome increasing industry-led momentum to find solutions to these threats. Newtec is very supportive of and active in industry-wide initiatives and efforts to counter and reduce the impact of carrier interference.

“End-user dissatisfaction is unacceptable and so we are pleased to see so many stakeholders in the satcom industry working together. It is vital though that we choose the right solutions that will serve us all well in the years to come.”
One preferred longer term plan within the industry is a data-agnostic solution for identification of modulated video and data satellite carriers.

Van Herck added: “We believe it is imperative that the solution we arrive at be a standard based solution under the auspices of a recognised standardisation body such as DVB. It must be unencumbered by intellectual property restrictions whilst being very robust and able to reconstruct the Carrier ID at low signal levels and/or high levels of interference.”

Newtec has already begun talks with industry players and convinced leading satcom manufactures to join this initiative. It is also preparing an update of its current product range to implement this feature.

There are a number of solutions in Newtec’s portfolio that already include interference counter-measures such as FlexACM®, which ensures a stable satellite link during interference, and also MENOS®, with its automatic booking system to avoid manual errors (NIT support).
