Harris Corporation to Introduce New Transmitter for China’s DMB-T Standard at BIRTV
will introduce its first transmission solution for
Digital Multimedia Broadcast-Terrestrial (DMB-T) standard at the upcoming BIRTV
China. The company also
announced it is shipping its first DMB-T transmitter to Yunnan TV in
China later this month, and will provide upgrade
kits for Harris DVB-T transmitters currently installed in
will debut a DMB-T transmitter outfitted with a new Harris DTV660 DMB-T exciter
at the show (
August 23-25th, Booth 8A-30). The DTV660 DMB-T exciter is based on Harris
Corporation’s field-proven range of Digital Video Broadcast-Terrestrial (DVB-T)
standard exciters, and features a new modulator designed specifically to meet
the new Chinese digital TV standard. The new DMB-T transmitter uses
Harris Atlas technology, which includes a variety of solid-state, air-cooled and liquid-cooled analogue
and DVB-T digital transmitters.
Atlas DVB-T transmitters already in the field today can easily be upgraded to
the DMB-T standard with a simple board swap and firmware changes.
“Harris is pleased to support
China’s DMB-T standard for digital terrestrial
television,” said Tim Thorsteinson, president of Harris Broadcast
Communications. “Harris has a long history of leadership in transmission,
and continues to design new platforms and modify existing technology to support
digital TV standards internationally. We look forward to supporting this unique
moves forward with its DTV initiatives for both terrestrial and mobile TV broadcasting.”
The DMB-T standard has been designed to provide the best possible reception
quality, even in large metropolitan areas with difficult reception conditions.
The standard has been engineered to provide a very high level of spectral
efficiency. This provides the capability to transmit multiple programs of
video, audio and data within the same channel that was previously occupied by a
single analog signal. The standard is also designed to allow both terrestrial
TV sets and mobile handheld devices to use the same spectrum.
The medium- to high-power liquid-cooled design of Harris DMB-T transmitters is
specifically for broadcasters seeking an efficient, high-power density
transmitter, resulting in greatly reduced room air-conditioning requirements
and overall electricity costs. The new Harris DMB-T transmitter series also
shares the compact footprint of the Atlas transmitter design for broadcasters
with limited space in the transmission facility.
past three years, BIRTV Awards have been granted to several Harris Atlas transmission
products, including the DVB-T range in 2004; the Atlas Analogue and DVB-T transmitters
in 2005; and the Atom channel gap filler in 2006.
