Description
Summary:An experiment in which digital high definition television broadcasts originating at the facilities of UHF television station WMVT, channel 36, in Milwaukee, Wisconsin, were received at the facilities of Zenith Electronics Corporation in Glenview, Illinois, approximately 70 miles distant, is reported. The broadcasts used the Zenith/AT&T Digital Spectrum Compatible High Definition Television System proposed to the Federal Communications Commission Advisory Committee on Advanced Television. The digital signal was received at the 70 miles distance except for very infrequent intervals of fading in early experimentation. A mobile test vehicle 40 to 50 miles distant received the digital signal without error. Cochannel interference from a low-power television station was effectively suppressed.< >
