Interlaced video is a technique of doubling the perceived frame rate introduced with the signal used with analog television without consuming extra bandwidth. Since the interlaced signal contains the two fields of a video frame captured at two different times, it enhances motion perception to the viewer and reduces flicker by taking advantage of the persistence of vision effect. This results in an effective doubling of time resolution (also called temporal resolution) as compared with non-interlaced footage (for frame rates equal to field rates). Interlaced signals require a display that is natively capable of showing the individual fields in a sequential order. Only CRT displays and ALiS plasma displays are capable of displaying interlaced signals, due to the electronic scanning and lack of apparent fixed-resolution.
