De-interlacing [through] line doublers and comb filters whose processing strategy or formula varies, where coincidentally the optimum processing depends on whether the subject matter depicted was stationary/steady or moving/changing.  2, record 1, English, - motion%20adaptive%20de%2Dinterlacing

The best devices may vary their processing dozens of times within a single scan line. The device must digitize several video fields, save (buffer) them on a rolling basis, and compare the content in small groups of pixels to determine whether subject matter was moving or not.  2, record 1, English, - motion%20adaptive%20de%2Dinterlacing

Désentrelacement au moyen de doubleurs de lignes et de filtres en peigne dont les stratégies de calculs varient, compte tenu que le traitement optimal dépend du mouvement ou de l'immobilité des trames analysées.  3, record 1, French, - d%C3%A9sentrelacement%20adaptatif%20du%20mouvement

Record number: 1, Textual support number: 1 OBS

Un désentrelacement adaptatif est un algorithme plus avancé qui recherche une séquence d'images pour déterminer si une zone est immobile ou en mouvement. Lorsque les pixels sont immobiles, les trames sont simplement combinées, sans fondu. S'ils sont en mouvement, les trames sont fondues ensemble. Cette technique produit les meilleurs résultats visuels, mais est lourde à calculer.  4, record 1, French, - d%C3%A9sentrelacement%20adaptatif%20du%20mouvement

Record number: 2, Textual support number: 1 CONT

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 2, 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 2, 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 2, 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 2, French, - doublement%20de%20lignes

To remove interlacing from images ... for TV [television] broadcasting.  3, record 3, English, - de%2Dinterlace

Record number: 3, Textual support number: 1 OBS

Interlacing, invented in the 1940s, is probably the earliest form of video compression. Instead of transmitting a complete video frame 60 times every second, engineers discovered that they could halve the bandwidth needed by the TV signal if they sent alternately odd and even "fields", each field comprising just the odd or even picture lines.... When viewed on a progressive display device, such as a PC, two fields are interlaced to create one frame. Because half the frame's lines are captured a fraction of a second later than the other half, fast-moving objects may appear jagged, the result of the object advancing slightly within 1/60th of a second... It is possible to remove the jagged-edge interlace artifacts by applying a process known as "de-interlacing" to the video.  2, record 3, English, - de%2Dinterlace
