Demonstrations Show Technology Excels Under Real-World Broadcast Conditions LAS VEGAS, April 16 /PRNewswire/ -- Innovative digital television (DTV) technology allowing over-the-air broadcasters to reach viewers on the move was unveiled and demonstrated publicly for the first time today at the National Association of Broadcasters (NAB) convention. Developed by LG Electronics Inc. and Harris Corporation (NYSE:HRS), the MPH(TM) In-Band Mobile DTV system is capable of providing robust DTV signals to mobile, pedestrian and handheld devices. For broadcasters, this new technology promises to create new and potentially lucrative revenue streams. For consumers, MPH enables users to view their favorite programs from local broadcasters, watch movies and sports, and access local news and weather information -- even when traveling in fast-moving vehicles or using handheld video devices away from home. "Delivering robust DTV signals to a wide range of devices for mobile- portable-handheld applications is the final frontier in terrestrial digital TV broadcasting," said Dr. H.G. Lee, president and chief technology officer of LG Electronics. "In-band mobile DTV will give broadcasters new business opportunities and consumers exciting new products and services. That's what MPH is all about." Tim Thorsteinson, president of Harris Broadcast Communications said, "The robust and flexible MPH system maximizes broadcasters' use of their DTV channel, enabling them to deploy compelling handheld and mobile services, while continuing to deliver HDTV, SDTV and datacasting services. Broadcasters who have seen MPH in action share our enthusiasm about this new technology platform." BROADCASTERS ENTHUSIASTIC ABOUT MOBILE DTV "Mobile DTV is a major opportunity for U.S. broadcasters to use their digital TV spectrum to deliver value-added services to consumers interested in receiving video content in mobile settings," according to Brandon Burgess, president and CEO of Ion Media Networks, a founding member of the new "Open Mobile Video Coalition," an industry alliance to accelerate the development of mobile digital broadcast television. "Broadcasters are seeing the magnitude of this opportunity and are working collaboratively toward this goal. MPH is precisely the type of technology development broadcasters need from manufacturers to enable this opportunity. We are excited about what we have seen from Harris and LG, and we look forward to continue working with them and our fellow broadcast industry partners on building a mobile DTV video marketplace in the United States." David Donovan, president of MSTV, the Association of Maximum Service Television, whose members include TV broadcast groups and networks, underscored the importance of mobile DTV. "As broadcasters prepare for the successful conclusion of the DTV transition, many also are turning their attention to exploring new business models for video- and data-broadcasting outside the home," he said. "Broadcast television is by definition a wireless medium. Now my members are looking forward to the next big thing in broadcasting: handheld and mobile DTV, reaching more eyeballs and expanding our markets. New technologies such as MPH will give television broadcasters additional tools to provide new and innovative video services to the communities that we are licensed to serve," Donovan said. HARRIS, LG CONDUCT FIRST LIVE MPH PUBLIC DEMONSTRATIONS MPH In-Band Mobile DTV is debuting this week at the NAB convention with live, over-the-air demonstrations in a minibus traveling through Las Vegas and the nearby vicinity, including the signal-challenged canyon of high-rise hotels along the famed Las Vegas Strip. Two mobile MPH streams are being transmitted simultaneously with the normal DTV programming of Sinclair Broadcast Group's local affiliate of the CW, channel 29. KVCW-DT. One of the MPH streams is the real-time MPH encoded version of the normal channel 29 program, to demonstrate that a local broadcaster's normal programming can indeed be received "on the go." "Historically, Sinclair has been a proponent of mobile and portable digital television. So, we are very excited to see LG and Harris demonstrate the MPH system at NAB 2007," said Del Parks, Sinclair's vice president of engineering and operations. "Sinclair is glad to assist with this technology launch by providing our Las Vegas station's DTV channel 29 for this demonstration. We encourage all of our fellow broadcasters to take the mobile tour and see for themselves what is possible." These mobile demonstrations offer industry executives, government guests and the news media an opportunity to experience first-hand the reliability of the Harris-LG system under real-world conditions. The new technology also is on display at both the Harris booth and the Advanced Television Systems Committee exhibit at the NAB trade show. FIELD TESTS YIELD PROMISING RESULTS The LG-Harris minibus mobile DTV demonstrations follow successful field tests conducted early last month in Columbus, Ohio. Receiving the MPH signal from WBNS-DT/Channel 21, Dispatch Broadcast Group's CBS affiliate in Columbus, the LG-Harris system tested well across a wide range of challenging locations. In addition to enjoying excellent reception in the downtown business district, the technology performed flawlessly at the 55-mile-per-hour speed limit on the Columbus beltway, the interstate highway that rings the metropolitan area. "Seeing is believing," said Dispatch Broadcast Group President and CEO Michael J. Fiorile. "Our company's CBS station in Columbus was proud to run the world's first broadcaster field test of the MPH system. I rode in the test van as we drove around town -- on the interstate, under overpasses, through downtown streets and along suburban boulevards. Receiving DTV signals from our transmitter at 55 mph was impressive. Equally impressive was the fact that we were broadcasting HDTV on the main channel and mobile services on the MPH channel at the same time. No question about it, mobile DTV is a key to our future." In the field tests, a simple 7-inch un-tuned whip antenna achieved successful reception at highway speeds, including through underpasses; error- free hand-held pedestrian reception at the 38-mile horizon for handheld devices; 97-99 percent error-free reception in blocked urban canyons; successful reception for mobile and pedestrian applications at residential locations within a 10-mile radius of the transmitter; and successful reception in suburban, rural and industrial locations -- all without multiple receiving antennas. TWO-YEAR DEVELOPMENT EFFORT BEHIND MPH The MPH system capitalizes on the powerful combination of Harris Corporation's expertise in broadcast systems -- including transmitters, exciters, encoders and software -- and the system development, integrated circuit design and vast consumer electronics experience of LG Electronics and its U.S. R&D subsidiary, Zenith. The in-band mobile DTV technology, under development for nearly two years at the LG Electronics DTV Laboratory in Seoul and at LG's Zenith lab in Chicago, builds on two key ATSC standards, also developed by Zenith: the robust Enhanced VSB (E-VSB) system and 8-VSB, the proven modulation system at the heart of the well-established ATSC DTV broadcast standard currently used by more than 1,500 U.S. DTV broadcasters and in every DTV receiver sold in the United States. To help commercialize its technology concepts for the broadcast industry, LG Electronics turned to long-time DTV industry leader Harris Corporation's Broadcast Communications Division. Harris Corporation's extensive systems integration expertise and research capabilities contributed significantly to the broadcast system development. According to Harris and LG, the overarching goal of the joint development effort was to devise a robust, ATSC-compatible mobile solution for local broadcasters to maximize the use of their 6-MHz, 19.39 megabit-per-second digital pathway in delivering a wide range of compelling and profitable consumer services. This meant maintaining the centerpiece application, digital high-definition television (HDTV) to the tens of millions of fixed receivers in consumer homes, while reaching viewers on the go with a low-bit-rate digital TV signal and data services.
