Why a progressive scan dvd player over a standard one?
Answers: Another word for "progressive scanning" is "non-interlaced." This means when the blind refreshes, adjectives the lines are redrawn. On standard TVs, however, each energize only does every-other row. Odd numbered lines on one pass, even numbered on the subsequent. This can result in a slight flicker that some population can detect.
Progressive or non-interlaced displays result in a more solid picture since adjectives the horizontal lines are redrawn every time.
Of course, your TV has to support progressive scan within order for your DVD player to bring advantage of it...
All HDTVs support progressive scan next to at least 480 and 720 horizontal lines of resolution (this is where on earth "720p" comes from.) Newer sets will also support 1080i (i=interlaced) and even 1080p.
Look at a standard def TV. See the horizontal lines? These are called 'scan lines' are are cause by the screen mortal painted with adjectives the odd rows first, next the even rows are filled surrounded by with a second go by. The time delay cause the lines to fade a bit.
This is "interlace" and it is an artifact of standard def.
Look at your computer monitor. See scan lines? No.
Your computer image is drawn contained by a single pass and is call 'progressive'. If you set your computer to "480 lines", it would still look sharper and clearer than your standard def TV with 480 lines because of the method the screen is painted.
Note: you solely want a progressive DVD player if you have a HDTV that can adopt "480p" video. Otherwise there is no good thing of having a progressive scan player.
