LG Electronics Co. says it has developed a low-cost way for North American TV stations to transmit digital signals to cellphones and other portable gadgets.
LG's technology, which it calls MPH for mobile-portable-handheld, requires TV stations to buy relatively inexpensive add-on devices to their digital transmitters and the makers of cellphones and other portable devices to install a reception chip. The reception technology can also be incorporated into other chips in portable device.
