Disruptive Digital Precorrection for VYPER at SATSHOW

National Harbor (MD), March 7, 2016TeamCast, the world-renowned leader in digital modulation technologies for Digital Terrestrial Television (DTT), Wireless Transmission and Satellite Applications, is introducing a new key feature for its successful Vyper satellite modulator at Satellite2016.

Digital pre-correction of the satellite’s signal chain is a technical challenge. First generation solutions have been available on the market for a few years. The benefits they bring are not as high as expected, especially for the low order constellations which are the most widely used: QPSK and 8PSK.

TeamCast is introducing a new and innovative digital pre-correction solution on its VYPER range of satellite modulators. This second generation technique offers significant gains in budget margin, from 1.5 dB for 8PSK to 5 dB for 32APSK. It is available as a simple software upgrade for the VYPER modulators.

“This second generation solution is very efficient and will be usable with widely used constellations such as QPSK and 8PSK, while previous techniques are only efficient with high order constellations (e.g. 16APSK and 32APSK), which makes them of limited interest. Thanks to this technology, our broadcast partners (especially DTH partners) could improve their bitrate by 10% without changing their set top boxes recievers. Again, we are bringing new opportunities to operators through the disruptive technologies available for our VYPER range» says Christophe Trolet, Business Unit Manager at TeamCast.


This new Vyper pre-correction solution will be demonstrated on TeamCast’s booth #2129.
