As the US stumbles forth into the age of digital television, Zenith is pretty much sitting in the catbird seat. That's not because Zenith and its parent company, LG Electronics, make a slew of HDTV-ready monitors, integrated HDTVs, plasma displays, and LCD TVs (they do); nor is it because they're one of two major manufacturers of ATSC set-top receivers (they are). It's because Zenith holds the patents on the 8VSB modulation system employed for terrestrial digital television. As each new Zenith receiver and integrated HDTV comes to market, the company is pretty much in the lead with the latest 8VSB demodulator chipsets.
