Progressive scan DVD player
Encyclopedia
A progressive scan DVD player is a DVD player
that can output video in a progressive scan
format such as 480p
(NTSC
) or 576p
(PAL
). Players which can output resolutions higher than 480p or 576p are often called upconverting DVD players.
Before HDTV
s became common, players were sold which could output 480p or 576p. TVs with this feature were often in the upper price range of a manufacturer's line. To utilize this feature, a TV or other display with a progressive scan input was needed. HDTVs usually have a progressive scan input; progressive scan inputs are less common on standard definition TVs (often called SDTVs.)
Some players have a feature called "3:2 pulldown detection" or "inverse telecine
" which attempts to better handle the artifacts which result from differing film and video rates in conjunction with interlaced scanning of the film.
Progressive scan output can not use connections intended for interlaced video, such as composite video
(single RCA
terminated cable) and S-Video
(Mini-DIN
terminated cable). The following connection methods are common for using Progressive Scan:
