Field Vs. Frame Calculations for Visual Channel Delay

Stephen Wolf

Abstract: This contribution recommends that calculations of visual channel delay be based on fields rather than frames for an interlaced video system such as NTSC. Using fields rather than frames will double the resolution of the measurement without significantly increasing the complexity and will overcome certain measurement anomalies that might result from calculations based on frames.

Keywords: video; delay; variable; NTSC; field; frame; rate; constant
