DVB-S2X (Extensions) - new satellite transmission standard

[jayanji]

What's Next After DVB-S2?

Kick-started by Newtec earlier this year, key players in the satellite industry are calling for a satellite transmission standard, specifically for professional satellite contribution links, which would extend the existing DVB-S2 standard.

Our Industry Is in (R)evolution:

When comparing the current DVB-S2 standard against the full implementation of S2 Extensions (activating smaller Roll-Offs, advanced filtering, 64 APSK and wideband) staggering efficiency gains up to 64% can be achieved for professional applications over satellite. For DTH networks up to 20% efficiency increase can be obtained. These gains already exceed the results by proprietary systems in the market today.

S2 Extensions Improvements

1. Smaller Roll-Offs
2. Advanced Filtering
3. Supporting Different Network Configurations
4. Increased Granularity in MODCODs
5. Higher Modulation Schemes up to 64APSK
6. Linear and non-linear MODCODs
7. Wideband Support up to 72 Mbaud

RE: DVB-S2 Extensions - new satellite transmission standard

At today's 76th meeting of the DVB Steering Board, the Board voted to approve the eagerly awaited new extensions to the DVB-S2 specification. The new enhanced specification, known as DVB-S2X, offers spectral efficiency gains for professional applications by up to 20 -30% and for some scenarios, gains of up to 50% can be achieved. In addition, new operational modes such as channel bonding increase flexibility. The specification will now be sent to ETSI for formal standardization and the DVB-S2X BlueBook will be published shortly.

"Throughout the technical activity, I was impressed to see European, US and Far East companies, operating in different business environments such as broadcasting, VSAT or DSNG playing together, as if in a symphonic orchestra, to design a state of the art common system," said Alberto Morello, Chair, TM-S2.

Peter Siebert, DVB's Executive Director added "We are delighted that the Steering Board has now approved the new DVB-S2X specification and I would like to congratulate all the Members that have actively contributed to bringing about this step forward in updating the excellent DVB-S2 standard. The satellite industry has been anxiously awaiting this standardization which will help it to improve profitability, interoperability and achieve further growth".

RE: DVB-S2 Extensions - new satellite transmission standard

In March 2014 the DVB-S2 specification became a 2-part document to accommodate the new DVB-S2 Extensions (DVB-S2X).

The DVB-S2 will remain a stand-alone specification and the DVB-S2X specification is optional.

DVB-S2 = BlueBook A83-1 / EN302307-1

DVB-S2X = BlueBook A83-2 / EN302307-2

You can get the new DVB-S2X logo by registering on DVB Services

Are DTH STBs compatible with DVB-S2X standard...? Can it be mde compatible using a Sw update...?

New professional broadcast satellite modem and demodulator gives the best transmission performance, lowers operational costs, delivers the highest uptime for vital links and seamlessly evolves towards tomorrow’s standards and technology



LAS VEGAS, NV, and SINT-NIKLAAS, Belgium. Satellite equipment specialist Newtec is launching its latest MDM6100 Broadcast Satellite Modem at NAB 2013, a next generation DVB-S, DVB-S2 and S2 Extensions modem specifically designed for broadcast applications.

A New Broadcast Modem Increasing Satellite Efficiency by up to 60%

The new modem is capable of increasing broadcast efficiency by up to 60% compared to DVB-S2, equipping broadcasters and satellite service providers with all of the latest modulation, multistream transmission and wideband transponder support.
The MDM6100 can act as a modem, modulator or demodulator, and can be used in conjunction with set-top boxes, professional Integrated Receiver Decoders (IRD) and satellite demodulators.

Seamless Migration to S2 Extensions Enabling UHDTV Contribution and Distribution

The MDM6100 is designed to migrate existing networks towards a more efficient S2 modulation in a smooth manner. The gained space segment can be used to transmit more content, including UHDTV services which demand a lot of bandwidth.
Migration of standard distribution links towards S2 Extensions can be achieved simply by inserting an MDM6100 modem in the receiving head-ends while keeping the installed base of IRDs. In those network topologies, the MDM6100 receives content using the efficient S2 Extensions, and provides this content to multiple IRDs over ASI, GbE or trans-modulated DVB-S/S2 carrier.

DVB Standardization Projects

Priority DVB projects such as S2 Extensions will become available on the platform as soon as the standardization efforts are complete. These will give up to 37% more efficiency compared to DVB-S2, and when combined with wideband (72 Mbaud) these savings will leap to almost two thirds. DVB-Sx modulation schemes will become available as a software only upgrade on the MDM6100 as soon as the DVB standard has settled. The new DVB-CID carrier identifier standard is already available as a software option on the MDM6100.
Steven Soenens, Product Strategy and Product Management Director of Newtec said: “Our new broadcast modem enables systems to easily migrate to Multistream and S2 Extensions paving the way to the distribution of more broadcast content. In one simple move it prepares a business for S2 extensions, HEVC and UHDTV. It allows the re-use of existing infrastructure and reduces satellite interference through DVB-CID.”
Last month Newtec’s related product, the M6100 Satellite Modulator that launched in 2012, won the WTA Teleport Technology of the Year award at a prestigious ceremony in Washington to celebrate the best of the industry.
