'''Progressive segmented Frame''' (PsF, sF, SF) is a scheme designed to acquire, store, modify, and distribute [[progressive scan|progressive-scan]] video using [[interlaced]] equipment and media.

With PsF, a progressive frame is divided into two ''segments'', with the odd lines in one segment and the even lines in the other segment. Technically, the segments are equivalent to interlaced ''fields'', but unlike native interlaced video, there is no motion between the two fields that make up the video frame: both fields represent the same instant in time. This technique allows for a progressive picture to be processed through the same electronic circuitry that is used to store, process and route interlaced video.
