Robust MPH" Digital TV Delivered to Moving Vehicles, Handheld Receivers

Robust MPH" Digital TV Delivered to Moving Vehicles, Handheld Receivers
LAS VEGAS, Jan. 6, 2008 - Clearing one of its toughest technical hurdles to date, the MPH" in-band mobile digital television (DTV) system has been successfully broadcast throughout the Chicago media market - including its architecturally-famous but signal-challenged canyons of downtown skyscrapers - in an extensive six-week field trial.
Developed by LG Electronics Inc., its U.S. R&D subsidiary Zenith and Harris Corporation (NYSE:HRS), MPH is capable of providing robust over-the-air DTV signals to mobile, pedestrian and handheld devices. For consumers, the MPH system 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. For broadcasters, this new technology promises to create lucrative new revenue streams.
The Chicago field trials were conducted from Nov. 12 through Dec. 21, in cooperation with a major local television station whose DTV signals originate from a digital transmitter located atop the Sears Tower. Received and displayed in test vans traveling throughout Chicago and its suburbs, two mobile MPH streams were transmitted simultaneously with normal DTV programming.
"As broadcasters move ahead to launch exciting mobile DTV services in 2009, MPH is ideally suited to deliver robust reception as shown by the extensive field trials in Chicago," said Tim Thorsteinson, president, Harris Broadcast Communications.
LG Electronics President and Chief Technology Officer Dr. Woo Paik, said, "Thousands of data-points in our Chicago DTV measurements prove that MPH is the ideal foundation for broadcasters to capitalize on a wide range of business models."
MPH delivered excellent reception downtown - from The Loop to Lincoln Park, from Bridgeport to the Gold Coast, even on Lower Wacker Drive, which runs under buildings and other streets. The technology
performed flawlessly at the 55-mile-per-hour speed limit on Chicago-area interstate highways, including the Kennedy, Edens, Dan Ryan and Eisenhower expressways, to name a few. Similarly, the MPH signals were received well in hundreds of suburban and rural locations, from Naperville and Oak Park to Libertyville and Evanston, up to 30 miles from the Sears Tower transmitter.
In the Chicagoland tests, a simple 7-inch un-tuned whip antenna achieved successful reception of the programming at highway speeds, including through underpasses; error-free handheld pedestrian reception as far away as Racine, Wis; reception in blocked urban canyons; successful reception for mobile and pedestrian applications at residential locations within the station's service area; and successful reception in suburban, rural and industrial locations - all with a single receiving antenna.
The MPH system capitalizes on the powerful combination of Harris Corporation's expertise in broadcast systems - including transmitters, exciters, encoders and software - and the systems 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 more than two years at the LG Electronics DTV Laboratory in Seoul, South Korea, and LG's Zenith lab near 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 1,600 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's development.
The overreaching 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,'.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 simultaneously reaching viewers on the go with robust mobile digital TV signals and data broadcasting services.
Harris is an international communications and information technology company serving government and commercial markets in more than 150 countries. Headquartered in Melbourne, Florida, the company has annual revenue of over $4 billion and 16,000 employees - including nearly 7,000 engineers and scientists.
