Newtec S2 Extensions Survey: Some Striking Results (3 of 3)


By Koen Willems, Strategic Marketing Director;

In the two previous posts (article 1 of 3 and article 2 of 3) we have discussed the interesting results that came out of the extensive online survey on S2 Extensions. Following five conclusions were made:

  • 98% of the respondents regard standards as (very) important.
  • One out of two respondents will use S2 Extensions within 1 year.
  • 62% of the respondents will use S2 Extensions if it at least offers 15% to 20% efficiency gain.
  • 40% of the respondents will increase their throughput in the same bandwidth.
  • 1 out of 2 respondents think that the efficiency race will continue as long as satellite exists.

This time, we will tap into the concerns that go along with the launch of the new DVB standard and already provide some answers on some common misconceptions.

What are the biggest concerns when S2 Extensions will be implemented?

Whenever new technologies are introduced, questions need to be answered. How will S2 Extensions affect my current and future business? What kind of price tag goes along with the introduction of a new DVB standard and how will it improve the profitability of the company?

Following 3 quotes perfectly translate common worries in the market place:

“The biggest concern will be the cost of reconditioned or, if necessary, brand new replacement equipment to adopt to this new standard.”

“No big concern but potential interoperability problems during a transition period.”

“Can I enjoy my current park equipment used today for this new standard making updates?”

Some general challenges with the implementation of S2 Extensions were captured in the final survey question towards the satellite expert community.


From Challenge to Opportunity

Mainly the costs to replace existing equipment (24%) could be a barrier for the implementation of the S2 Extensions if it is not tackled in the correct way. 

But where to start?

Firstly, a link budget calculation between current operations and the optimized S2 Extensions will reveal the efficiency gain for your business.

You will find the S2 Extensions calculator on the Newtec website to assist you in your calculations. The gains from 7,5% on average for lower MODCODs up to 37% for the higher MODCODs will allow you to perform a Return-on-Investment (ROI) estimate. The end result will convince your management to switch towards S2 Extensions for your operations over satellite in the shortest time frame.

Secondly, an S2 Extensions demodulator can easily be placed before a bank with existing IRDs. The demod will interface with the IRD through ASI/GbE or will act as transmodulator from S2 Extensions to S2 for professional video distribution. In other words only a demodulator needs to be replaced instead of the entire IRD infrastructure.

Do We Talk the Same Language?

DVB-S2 and S2 Extensions are not compatible due to the improvements to the FECs and MODCODs. Moreover different classes have been made for linear and non-linear MODCODs. As such the question on interoperability (18%) in the satcom market place is pretty valid.

Currently Newtec already partners with all major system houses to implement S2 Extensions into their upcoming products, which will facilitate interoperability over time. In this framework the Newtec modulators and modems are used as compatibility benchmark across the industry.

Newtec latest modem products have both DVB standards on board and can easily be migrated from DVB-S2 to S2 Extensions to allow for a smooth transition.

What With the DTH Set Top Boxes?

How will the new DVB standard impact the Direct-to-Home market? Will all receivers need to be replaced when implementing the new standard? Or can we select a path in-between where consumers can keep their current infrastructure? 

The good news is that the implementation of S2 Extensions coincides with the introduction of the High Efficiency Video Coding (HEVC) standard to support the request for higher quality images in Ultra-High Definition TV (UHDTV) by the market somewhere in 2014. The DTH provider can take full advantage of the synergies between the two standards in order to provide the best efficiency and increase profitability whilst offering an attractive TV package to their customers.

If the DTH provider needs to stick to the installed base set top boxes or receivers and still wants to benefit from efficiency improvements Clean Channel Technology™ is the best option. Clean Channel Technology is part of the S2 Extensions implementation and combines the smaller roll-off (5%,10%,15%) functionality with advanced filter technologies to put carriers closer to each other. Clean Channel Technology can be executed on top of DVB-S2 in full compatibility with existing in-the field receivers.

Clean Channel Technology is available on Newtec’s professional equipment. Both as a software field upgrade for installed based equipment as well as new Newtec equipment.
