DVB WORLD 2013 – MADRID Proprietary systems that have appeared on the market over the last two years have outperformed the DVB-S2 standard quite significantly, according to Thomas Wrede, vice president reception systems, SES.
Wrede said that improvements in the transmission standard of a gain of 20% on a standard DTH satellite transponder and even 30% on wideband was something that could not be ignored.
The as yet unnamed version is currently referred to DVB-SX.
“With the increased granularity we get a significant gain within the spectral sweet spots… with higher modulation gain we can get even closer to the Shannon Limit,” Wrede, the chair of the DVB’s commercial module for BSS, told delegates at DVB World.
“We don’t want a too fundamental change in the structure of DVB-S2 as the chip at the end has to be affordable. We want to have this back to a DVB standard as soon as possible.”
Wrede said the real mass market would come by combining the HEVC video compression standard and the new DVB-S2 extensions onto a system on a chip for ultra HD receivers. “The technology of integration of getting more on the chip and getting it there faster has become more feasible. In the early ’90s I remember discussions that said it would be complex and expensive, but the manufacturers have now shown that it is possible”.
Quoting research conducted by Newtec, Wrede said he was cheered by the fact that more than 60% of users would take advantage of the improvements in efficiency.
