Well. let's see: "With Dotcast?s patented data insertion and extraction techniques, the dNTSC system can provide unimpaired analog television viewing while simultaneously delivering errorfree, rich multimedia content to a TV station?s Grade A contour?for example, about 1.7 million people in Los Angeles, CA for an ABC affiliate station."
