Harris Corporation, LG Electronics Announce In-Band Mobile DTV System, Providing New Business Opportunities for Broadcasters

    MPH(TM) system to debut at NAB 2007

    CINCINNATI and CHICAGO, April 3 /CNW/ -- The inventor of the transmission
standard for digital television (DTV) and the market leader in broadcast
equipment and automation technology today announced an innovative new
technology designed to extend over-the-air broadcast TV signals beyond the
living room to viewers on the go.
    LG Electronics Inc. and its U.S. research subsidiary, Zenith Electronics
Corp., joined forces with Harris Corporation (NYSE:   HRS) on the development of
new in-band mobile DTV technology. The MPH(TM) in-band mobile DTV system,
dubbed "MPH(TM)" for "Mobile-Pedestrian-Handheld," will make its debut at the
National Association of Broadcasters (NAB) convention April 14-19 in Las
    This promising technology, which has the potential to create new markets
and revenue streams for TV broadcasters, will be prominently featured in two
high-profile NAB exhibits: the Harris booth (N2502, Las Vegas Convention
Center) and the Advanced Television Systems Committee "Hot Spot" (South Hall
upper lobby). The robustness and reliability of the new system also will be
showcased in live, mobile demonstrations throughout the NAB convention.
    "MPH(TM) is designed to deliver the Mobile-Pedestrian-Handheld
applications that digital TV broadcasters are seeking," said Dr. Jong Kim,
president of LG's Zenith R&D Lab, which collaborated with the LG DTV Lab in
Seoul and with Harris Broadcast Communications Division on the development of
the system. "We believe broadcasters will appreciate both the superior
performance and unparalleled flexibility of our MPH(TM) system."
    Tim Thorsteinson, president of Harris Broadcast Communications said, "The
results of our joint development with LG Electronics are in response to our
customers' interest in a compelling, in-band mobile solution. The versatile,
robust MPH system is the first that strikes the right balance for broadcasters
looking to deliver both high-definition programming to fixed receivers and
standard-definition programming and datacasting to mobile and handheld
    The MPH system is a multiple-stream approach, with the main service
stream for existing DTV and HDTV services, and the MPH stream for one or more
mobile, pedestrian and/or handheld services. Key attributes of the MPH system
    -- Backward compatibility with the existing ATSC 8-VSB transmission and
       receiving equipment;
    -- Capability to receive broadcast signals at high (mobile) speed with a
       single antenna;
    -- Use of practical, small handheld receivers without the need for
       multiple antennas;
    -- Power savings in handheld receivers;
    -- Flexibility in both data rates and robustness;
    -- Data-rate efficiency, and;
    -- Use of advanced video and audio coding in the MPH(TM) stream.

    The MPH system has the additional advantage for broadcasters of involving
neither outside service providers nor spectrum-pooling arrangements.
    During the NAB convention, in addition to conducting the live mobile
demonstrations, LG Electronics, Zenith and Harris will disclose results of
field testing under real-world conditions for mobile and handheld services.
Further details will be discussed at a joint Harris-LG press conference in Las
Vegas on April 15, the eve of the NAB convention.
