More ‘DigiCipher’ for NESN

New England Sports Network has expanded its use of Motorola Inc.’s “DigiCipher II” encoding system to provide HD broadcasts of Boston Red Sox Major League Baseball and Boston Bruins National Hockey League home games to subscribers, the vendor said Tuesday.

The network will use the DigiCipher II HD encoder at its uplink facility in Needham, Mass., to compress live game feeds originating from Fenway Park and the FleetCenter.

At the uplink, both standard-definition and HD content is multiplexed together, encrypted and broadcast using quadrature-phase-shift-key satellite modulation to downlink sites throughout New England, Motorola said.

“The flexibility of the Motorola system architecture has allowed us to grow our network from a single channel utilizing a partial transponder back in 1996 to a full transponder carrying three standard-definition channels and a high-definition broadcast," NESN chief engineer Dave Desrochers said in a prepared statement.
