Keywords:Harris LG Zenith? MPH in-band technology? DTV signal handset?

Harris, LG Electronics and LG subsidiary Zenith Electronics have demonstrated a new "MPH" in-band technology for receiving over-the-air DTV signals in handsets. By unveiling the technology, the companies aimed to counter mobile DTV demonstrations by Samsung at January's Consumer Electronics Show.

MPH, a reference to mobile-pedestrian-handheld, is based on two Advanced Television Systems Committee vestigial sideband standards, enhanced VSB and 8-VSB. The Samsung demonstration was based on advanced VSB. Harris intends to market the capability directly to broadcasters, who can deploy high-definition, standard-definition and datacasting services over the air to mobile platforms.

During the recent National Association of Broadcasters show, the companies were transmitting two mobile MPH streams along with DTV programs using the local Sinclair Broadcasting CW network affiliate, Channel 29 KVCW-DT. The tests duplicate ones held in March in Columbus, Ohio. Using minibuses at a variety of speeds up to 55mph, the tests utilized untuned 7-inch whip antennas to receive signals with 100 percent error-free reception, including under highway overpasses.

The companies reported error-free handheld pedestrian reception up to the 38-mile horizon of such devices, and reception at 97 to 99 percent error-free rates in "urban canyons," such as those among the high-rises along the Las Vegas Strip. Reception does not require a dual-antenna configuration.
