Progressive segmented frame

A scheme designed to acquire, store, modify and distribute progressive-scan video using interlaced equipment.

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

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.

The term progressive segmented frame is used predominantly in relation to high definition video. In the world of standard definition video, which traditionally has been using interlaced scanning, it is also known as quasi-interlace, progressive recording or movie mode. Other names for PsF used by electronic equipment manufacturers include progressive recording (Sony), progressive scan mode (Sony), progressive shutter mode (Sony), frame shutter mode (Sony), frame mode (Panasonic and Canon), Digital Cinema (Panasonic), Pro-Cinema (Panasonic) and Cinema mode (Canon).
