Year-Long Trial With Harris Atlas(TM) Digital DTV660L DVB-T
Transmitter Proves Technical and Commercial Viability for DVB-H in
Australia SINGAPORE, June 20 /PRNewswire-FirstCall/ -- The July
2005 launch of the world's first high-power trial of digital video
broadcast to handheld (DVB-H) technology marked an important
milestone for digital television. Conducted over the past year by
Broadcast Australia, Australia's leading independent broadcast
transmission provider, using an Atlas(TM) Digital DTV660L liquid-
cooled DVB-T transmitter from Harris Corporation (NYSE:HRS), the
DVB-H trial aimed to test the technical capability and commercial
prospects for DVB-H applications in Australia and globally. For
this trial, Broadcast Australia worked with Harris,
telecommunications provider Telstra, and wireless antenna and cable
manufacturer Radio Frequency Systems (RFS). Comprising the delivery
of 16 channels of live-streamed, diverse content to 400 trial
users, the trial explored the technical aspects and usage patterns
of multi-channel mobile media services. "By selecting the Harris
Atlas Digital DTV660L transmitters, Broadcast Australia has been
able to achieve its objectives for two high-profile digital
broadcasting trials," said Clive Morton, Broadcast Australia
broadcast services director. "In addition, the transmitters have
reduced operating costs through efficient energy consumption, along
with compact and quiet operation, while permitting easy monitoring
and control of the system from anywhere at anytime." Broadcast
Australia selected The Bridge Networks to supply a Harris Atlas
Digital DTV660L liquid-cooled DVB-T transmitter (operating in DVB-H
mode) for the task. The transmitter provides 3.4kW of power from a
single cabinet into an existing, multi-coupled UHF antenna system,
delivering 80kW effective radiated power (ERP), covering the major
part of the Sydney metropolitan area. Key benefits of the Harris
transmitter are its compact design and quiet operation. Being
liquid-cooled, it presents a single-cabinet footprint, while the
cooling system, pump module and heat exchanger are located
conveniently away from the main cabinet. This made it an ideal fit
into Broadcast Australia's newly built transmitter hall at the Gore
Hill broadcast site. Based on these attributes, Broadcast Australia
also decided to upgrade the transmission system of its digital
datacasting trial. This involved installing an identical Harris
3.4kW liquid-cooled transmitter (operating in DVB-T mode) in the
same transmitter hall. Since both systems now use the same model
transmitter, Broadcast Australia can employ common spare components
across both the DVB-H and datacasting trials, and enjoy streamlined
operations and maintenance procedures. The front-access, modular
design and redundant amplifier system provide the ability to
service the power amplifier modules on-air without service
interruption. The transmitter front-end user interface is common
for low- and high-power operation. The transmitter has been readily
integrated into Broadcast Australia's existing 24x7 Network
Operations Centre (NOC) for monitoring and forward control
purposes. The SNMP, GUI and Web browser interface make it easy for
the NOC team to interrogate the transmission system from the NOC or
any other location. About Harris Broadcast Communications Division
