Dr Peter SiebertThe DVB gave its approval onThursday to the much-anticipated extension to the DVB-S2 specification used in the transmission of digital video over satellite.

The new enhanced specification, known as DVB-S2X, offers efficiency gains for professional applications by up to 20 -30% and for some scenarios, with the DVB optimistic that gains of up to 50% can be achieved in some scenarios.

Peter Siebert, DVB’s executive director commented: “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”.

“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,” added Alberto Morello, Chair, TM-S2.

DVB-S2X provides more choices for roll-off factors as well as additional modulation and Forward Error Correction (FEC) options that allow for the more efficient use of satellite transmission channels.
