The DVB-S2X Modulator has been silicon-proven and is compliant with ETSI 302 307-2 standard.
In addition to complying with ISDB-T, the Si218x family supports the new DVB-S2X extension to the DVB-S2 standard for satellite reception.
Efficient satellite distribution technologies such as the DVB-S2X standard have been developed by the industry.
The modem leverages 256-APSK modulation, DVB-S2X and bi- directional Adaptive Coding and Modulation operation, which is the most advanced combination of space segment saving capabilities minimizing overhead.
Besides providing hands-on demonstration of industry equipment, the workshop will discuss topics such as DVB-S2X transmission and reception, 4K/Ultra HD (UHD) over DVB-S2X, as well as test and measurement and interactive services.

Both solutions offer satellite bandwidth efficiency by utilising the latest HEVC video compression and DVB-S2X satellite modulation technology, allowing a 50% reduction in leased satellite bandwidth compared to MPEG-4, DVB-S2 technology -- vastly reducing satellite OPEX.
To achieve the technologically challenging feat, NHK relied on DVB-S2X modulation, in 16APSK, and HEVC encoding.
Orbith selected Newtec to guarantee this throughput optimization using the Newtec Dialog[R] VSAT platform, including different application modems that support single carrier operation of up to 500 MHz and the latest satellite transmission standard, DVB-S2X, to maximize space segment usage.
Efficiencies, thus, can be improved by making use of technologies such as multi-stream, DVB-S2X and DVB-S2X channel bonding, he added.
The X10 and X20 support digital video broadcasting satellite (DVB-S2x) systems and digital satellite newsgathering (DSNG) with a new S2x contribution modulator and demodulator.
