Sky Italia deploys Newtec predistortion8 September 2011
Leading DTH provider Sky Italia is utilising Newtec’s Equalink DVB-S/S2 predistortion solution in connection with its innovative transmission solution. The installation is said to have resulted in a 10% performance increase, equating to an additional two channels on each of its 23 transponders.
Italian-based Communication Video Engineering supported Sky Italia throughout the implementation of Newtec Modulators and Newtec’s Equalink DVB-S/S2 predistortion systems.
Equalink predistorts the modulated signal to compensate for linear degradations generated by filters and non-linear degradations generated by satellite transponder amplifiers.
Sky Italia innovation and engineering manager Massimo Bertolotti said that having trialled other solutions, Equalink impressed the team by making sizable improvements of 80 Mbit/s in total.
“Using this solution we can transmit the signal closer to the saturation of the transponder and closer to the edge of the transponder frequency range,” said Bertolotti. “As a result, more power and more throughput are available, and therefore more channels and services for our customers.”
Serge van Herck, CEO of Newtec, commented: “Equalink allows Sky Italia to optimise its satellite transponder usage and increase the transponder value. Also, by using this solution Sky Italia is able to provide maximum performance – even on the edge of its footprint.”
