The
Harris® NetVX™ video networking platform,
which includes MPEG-4/H.264 and MPEG-2 encoding
modules, offers complete solutions inside and
outside the plant to encode, multiplex and transport
broadcast-quality SD and HD video for multiplatform
delivery services. Specifically, the NetVX ENC-A21
MPEG-4/H.264 video encoder now features IP-controlled
statistical multiplexing to more efficiently distribute
SD and HD video within a single NetVX chassis
or across multiple frames across the broadcast
facility. |
This
complete solution allows direct-to-home broadcasters
and service providers to more efficiently use existing
bandwidth, delivering more channels to the consumer
without the need to invest in additional transmission
bandwidth.
The
company is also showing new Videotek® DDM-6800+
demodulator modules for its 6800+™ processing
platform inside the plant. The new module offers RF
demodulation of 8-VSB, 64 QAM or 256 QAM to ASI transport
streams and provides a low-cost, space-efficient solution
for RF-to-fiber interconnectivity in the 6800+ frame
system when combined with existing 6800+ modules.
The
NetVX H.264 video networking platform is also ideal
for integration with Harris digital transmitters,
including the company's new ISDB-Tb digital transmitter
adapted for the Brazilian market. The Harris ISDB-Tb
transmitter and NetVX platforms offer a complete Harris
solution that includes an ISDB-Tb digital exciter
based on its Apex™ exciter platform and features
an integrated multiplexing solution for the delivery
of digital TV, HDTV and mobile TV programming over
the same transmission channel.
| The
Apex exciter has long been utilized by U.S. broadcasters
for the modulation of ATSC transmission signals
to enable the transmitter to produce a robust
over-the-air signal to support sharp, high-quality
digital TV and HDTV images. |

At NAB2008, Harris introduces its new Apex M2X™
MPH exciter, the world's first exciter to support delivery
of MPH™ in-band mobile DTV services with terrestrial
digital TV and HDTV services using the same slice of
bandwidth. The frequency-agile Apex M2X MPH exciter
is compatible with most digital transmitters, including
all Harris ATSC transmitters from its PowerCD®,
DiamondCD®, Sigma®, Platinum-i™, Ranger™
and Atlas™ product lines.
MPH
in-band mobile DTV, which is the ATSC-compatible mobile
TV solution jointly developed by LG/Zenith Corporation
and Harris Corporation, is just one of the many mobile
TV standards that Harris supports today. The NAB2008
mobile TV display also includes various Harris transmitters
and networking and infrastructure equipment to support
DVB-H, FLO™, ISDB-Tb, and T-DMB standards. Harris
is showing new low-power transmission solutions for
most of these standards, including low-power versions
of its Ranger™ transmitter for Qualcomm's FLO™
standard; and the low-power Atom Gap Filler transmitter
adapted for outdoor rooftop installations within DVB-H
mobile TV networks.
For
international mobile TV support, Harris is showcasing
its DMB 670-4000 transmitter for support of DMB mobile
TV and DAB digital radio programming over the same
transmission channel. The 4 kW DMB 670-4000 offers
twice the power of Harris' initial DMB 670 transmitter
introduction last year. The DBM 670-4000 supports
unprecedented power levels for DAB/DMB broadcasting
to provide a more robust transmission platform that
better serves consumers on the move.
Harris
NetVX video networking platforms and digital exciters
and transmitters are among the wide range of Harris
multiplatform delivery solutions that optimize the
video networking and infrastructure and transmission
workflows of today's broadcast operations.
