Abstract: Discusses the method of measurement used to obtain the frequency response or bandwidth values for each of the twenty-five video systems in the T1A1 subjective video experiment. The 25 video systems ranged in bit rate from 64 kb/sec to 45 Mb/sec. The bandwidth was measured using a traditional analog test waveform, in particular, a static zone plate (i.e., a two dimensional swept frequency waveform) that was on the standard video test scene tape.

Keywords: performance; measurements; video; quality; objective; frequency; bandwidth; conferencing; response; specifications; zone; plate
