Mobile TV transmission solutions from Harris
have been used to develop and prove the
effectiveness of the DVB-H, FLO and T-DMB
standards for mobile broadcast television.
The company will highlight its complete
mobile TV product range through four separate
demonstrations in the Mobile Zone. A Harris
NetVX networking system will deliver content
to the Mobile Zone from the main Harris
stand in some demonstrations.
DVB-H over UHF
The Harris DVB-H UHF solutions work in
both high- and low-power applications. The
higher-power Atlas liquid-cooled transmitter
(offered in versions from 1.25 to 9 kW)
is featured in the main Harris booth. In
the Mobile Zone, Harris is delivering DVB-H
content to a handset via the Atlas DTV-660
air-cooled UHF transmitter, which is offered
in power levels up to 1.5 kW.
DVB-H over L-Band
The Harris Cool Play Mobile TV transmitter
offers a 'convection-cooled' architecture
for outdoor installations. The 1670 MHz
version of the transmitter will transmit
video to a handset developed for Modeo,
a U.S. DVB-H operator. The Cool Play 1670
transmitter is available at power levels
up to 400 watts in L-Band.
FLO over UHF
The entire of range of Harris ATSC transmitters
are now available for FLO applications,
based on the new Harris Apex FLO exciter
that Harris is featuring in the Mobile Zone.
Harris will receive live transmissions of
a multichannel FLO service on a handset.
This marks the first Harris display in Europe
of FLO transmission products.
T-DMB over DAB
Harris has a full line of VHF and L-Band
DAB transmitters that can be used to deliver
mobile TV over DAB. In the Mobile Zone,
Harris will demonstrate the receipt of digital
radio channels and multichannel TV on a
T-DMB handset from a Harris DAB-660 transmitter.
Harris will demonstrate how the standard’s
highly efficient audio encoding allows for
transmission of multiple digital radio and
video channels using the same transmitter.
The company will display its strengths
in terrestrial TV transmission. The Harris
Atlas transmitter family will be prominently
displayed in the delivery section of the
Harris stand. As a global UHF transmitter
platform, the Atlas liquid-cooled transmitter
family supports analog, digital and mobile
television standards. Visitors can see an
active demonstration of the Atlas DVB-T/DVB-H
platform delivering HDTV and H.264 mobile
TV content. A widescreen display will receive
and broadcast the HDTV content, with the
H.264 mobile content received on a handheld
device.
The terrestrial TV area also will include
a demonstration of the Harris/Neural Audio
MultiMerge for DTV. MultiMerge uses intelligent
detection to blend any audio (mono, stereo,
matrix encoded stereo (L/R), and 5.1 discrete
content) into a seamless, uninterrupted
5.1 surround sound stream.
Harris began developing terrestrial transmission
platforms for mobile TV in 2004 after participating
in early demonstrations and the development
of the DVB-H standard. The company’s
recent acquisition of Leitch Technology
adds a range of servers, routers, switchers
and processing equipment to Harris®
NetVX video encoding and distribution systems,
providing the infrastructure for bringing
content into the mobile TV headend. Meanwhile,
equipment from the Harris Software Systems
business unit adds a complement of broadband
software and distribution equipment for
network management, traffic scheduling,
digital asset management and ad insertion,
among other applications.
