LAS VEGAS LG Electronics unveiled a new terrestrial digital mobile TV system at the Consumer Electronics Show called Mobile Pedestrian Handheld (MPH).
MPH is based on a variation of vestigial sideband, a demodulation technology currently used for U.S. terrestrial digital TV broadcasting.
In launching MPH, LG trotted out LG's CTO, Woo Paik, a key developer of the digital TV system in the United States. He spoke with EE Times editor-in-chief Junko Yoshida:
While working for General Instruments in 1990, Paik stunned the world by demonstrating that TV signals can be digitally transmitted. His effort, together with the work of others, prompted the U.S. to become the first nation to adopt digital technology as part of its terrestrial TV broadcast standard.
While the battle over the U.S. mobile TV standard is far from settled--market interest appears to be minimal--LG believes that MPH, which requires neither additional spectrum nor additional tower, has a chance to win on the market.
