Harris looks to mobile4 May 2006
With TV to mobile being one of the touchstones of NAB2006, Harris Corp sensibly covered all the bases by introducing transmitters for both FLO and DVB-H technologies at the show.
The FLO-specific versions of the Harris Atlas Mobile and Ranger Mobile TV transmitters are powered by the Harris Apex digital television exciter, featuring fully adaptive linear and non-linear correction for FLO requirements. Visitors to Harris’ Central Hall location saw Harris Atlas Mobile UHF transmitter delivering FLO mobile television services to a FLO-capable handset.
"Harris has been working with the development team at QUALCOMM MediaFLO Technologies since 2004 to develop a version of its Apex digital television exciter for FLO air-interface requirements," said Dale Mowry, vice president and general manager of the Harris Television Broadcast Systems business unit. "At NAB2006, we’re pleased to highlight the results of that effort: a complete range of television transmitters capable of transmitting FLO services."
On the DVB-H side of things, the company introduced Cool Play 1670, a new television transmitter platform specifically designed for 1670MHz DVB-H applications, including the Modeo mobile TV service planned for the United States. Featuring proprietary convection-cooled technology, it’s the first Harris mobile TV platform developed for harsh operating environments. Capable of operating at external temperatures from -40? to +45?C, it is uniquely equipped for outdoor installation without specialised cooling equipment. Specialised printed circuit board coatings and air-handling systems ensure that the electronics within Cool Play 1670 transmitters receive sufficient ventilation and cooling without corrosive effects from humidity or impurities in the air.
"The Cool Play 1670 is a clear indication of the commitment and innovation that Harris brings to mobile television applications," said Mowry. "Harris has applied the experience gained in mobile TV trials around the world to make a transmitter platform uniquely suited for the requirements of L-band mobile television transmission applications."
