VTC Hypothetical Reference Circuit Signal to Noise Ratio Measurements
Arthur A. Webster · 1994
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.
