Talk:Line doubler

Shouldn't this article link back to the deinterlace article? ABostrom 01:26, 2004 Dec 20 (UTC)

I would argue that this page is not correct. Line doubling and de-interlacing are not the same thing. A line doubler, as the name suggests, would be something that simply duplicates each line. This is what a VGA video card does when displaying a 200 line CGA-compatible mode for instance (because VGA monitors were designed to run at a 31KHz line rate and are generally incapable of running at the lower 15KHz scanrate used by a real CGA card). The purpose is to modify one progressive scan data stream to be displayed on higher resolution display. De-interlacing is different and more complicated, as the goal is to combine consecutive fields into one full-resolution frame. This requires buffering at least an entire field, if not a whole frame. It may also include filters to work around the artifacts resulting from the fields in the original stream being sampled at different times (commonly the case with SDTV signals).69.205.239.137 (talk) 08:08, 8 August 2008 (UTC)


 * I guess so but this one i can think deinterlacers like this which is linear deinterlacer and converts that framerate up and have smooth progressive playback.--HappyLogolover2011 (talk) 23:37, 10 April 2011 (UTC)
