Analysis of ATV transmission subsystem field test data

Abstract

This paper examines the data from the field test of the Grand Alliance HDTV transmission subsystem conducted in Charlotte, NC in 1994. The field test data provides HDTV system designers and researchers with first-hand information on the performance of digital HDTV terrestrial broadcasting as well as on NTSC performance in the real-world environment. Analyses of the field test data are performed with respect to the system performance of an 8-VSB digital transmission subsystem, the performance of NTSC as reference and the television channel characteristics. Observations and conclusions derived from the analyses are provided.
