At NAB2007, Harris Corp. and LG Electronics will be sponsoring demonstrations of live, over-the-air DTV signals being sent to mobile devices.
Harris and LG, along with its U.S. research subsidiary, Zenith Electronics Cop., have teamed up to develop MPH (Mobile-Pedestrian-Handheld), a proposed in-band DTV technology. The system is a multistream 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. Harris said the MPH system is backward compatible with current 8-VSB transmitters and receivers, can receive broadcast signals at a high (mobile) speed with a single antenna, provides power efficiency in handheld receivers, flexible data rates and robustness, and is compatible with advanced video and audio codecs.
In addition to conducting the live demos, LG, Zenith and Harris will disclose results of field-testing under real-world conditions for mobile and handheld services.
"The results of our joint development with LG Electronics are in response to our customers' interest in a compelling, in-band mobile solution," said Tim Thorsteinson, president of Harris Broadcast Communications. "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 devices."
NAB attendees can catch the demos at the ATSC Hot Spot, (South Hall upper lobby) and the Harris Booth (LVCC, N2502).
Harris publicly announced the proposed standard in February.
