New TV Chip

Motorola Inc. said it developed a chip, the MCT2100, with Sarnoff Corp. that overcomes “ghost” signal conditions. Tests show that digital TV signals can bounce off buildings and cars, causing the signals to arrive at TV sets at different times, resulting in a “ghosting” of images. TV stations serving about 70% of U.S. households are expected to begin airing digital signals by year’s end. The chip is designed for digital TV sets, DVD players and satellite and cable TV set-top boxes. It is expected to help TV stations meet Federal Communications Commission standards. Shares of the Schaumburg, Ill.-based firm rose $2.13 to close at $89.94 on the NYSE.
