Progressive-scan DVD players add an important additional step to create a better-looking picture - they generate a progressive-scan video signal through a process called de-interlacing (sometimes called "line-doubling"). The de-interlacer’s first task is to look at the interlaced video signal as it leaves the MPEG decoder and determine whether its original source was 24-frame-per-second film or 30-frame-per-second video. The original frame rate determines the type of processing necessary to create an optimized progressive-scan signal.  3, record 1, English, - line%2Ddoubling

Although "line-doubling" may sometimes be referred to as a synonym for "progressive scanning, "it is actually more generic in that it describes any basic process of image line doubling.  4, record 1, English, - line%2Ddoubling

Avec le balayage progressif numérique, l'image entière est balayée et affichée en une seule passe, 60 fois par seconde, soit deux fois plus vite que le balayage entrelacé. Ce procédé est fréquemment appelé doublage des lignes (line doubling).  2, record 1, French, - doublement%20de%20lignes

On a parfois tendance à associer en synonymie les termes «doublement de lignes» et «doublage de lignes» à celui de «balayage progressif». En réalité, le doublement (ou doublage) de lignes est plus générique en ce qu'il décrit toute situation de lignes d'image non entrelacées.  3, record 1, French, - doublement%20de%20lignes

Line quadrupling is similar to line doubling except that the number of horizontal scan lines are increased by a factor of four instead of two. Increasing the horizontal scan rate by a factor of four(to 63 kHz), allows most CRT's [cathode ray tubes] to obtain a range of optimum efficiency, maximizing light output with projector light output up to 60% brighter than NTSC, PAL, or SECAM displays. In addition to increased picture brightness, the image becomes smoother and has a "film-like" quality.  2, record 2, English, - line%20quadrupling

Le quadruplement de lignes se rapproche du doublement de lignes sauf que le nombre de lignes de balayage horizontales augmente par quatre au lieu de deux. Le quadruplement (jusqu'à 63 kHz) du taux de balayage horizontal permet aussi à la plupart des écrans cathodiques d'atteindre un rendement optimal et une luminosité accrue.  1, record 2, French, - quadruplement%20de%20lignes

A star target printed along with the job represents a small section of image edge, such as type or a halftone dot. Changes in the edge shape due to slur, doubling, or "squash" are greatly magnified and can be detected readily. Due to the target's symmetrical design, such changes can be differentiated and assigned to the correct cause.  2, record 3, English, - star%20target
