ANSI T1A1 Contribution T1A1.5/94-103, January 17, 1994.
Arthur A. Webster; Coleen T. Jones
Abstract: Discusses the method of measurement used to obtain the signal to noise ratio (SNR) 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 signal to noise ratio (SNR) was measured using a traditional analog test waveform, in particular, the 55 IRE flat field test signal that was on the standard video test scene tape.
Keywords: performance; measurements; noise; video; quality; objective; conferencing; SNR; specifications
