![]() The fellow on YouTube ignors the processing that goes on in a progressive plasma/LCD-TV and is totally wrong about his 540p arguement even for CRT and RPTV sets. (There are " super resolution" scaling techniques but I don't think any upscaling DVD player does this.)Ĭheck out this overview on interlace. About the best you can hope for is for it not to introduce too many scaling artifacts. Oh, and upscaling standard definition DVD doesn't make it high definition. You have to try both options with different sources and you have to know what defects to look for. This is one reason why much sports (ESPN for example) is broadcast at 720p.Īll the processing going on makes it impossible to predict what will look better on an HDTV. Smart deinterlacers will maintain the full resolution in non-moving areas but will fall back to half (vertically) resolution in moving areas. A good 1080i film source will look sharper on a 1080p HDTV than on a 720p HDTV (assuming you are sitting close enough to the TV to see the difference).įully interlaced 1080i (live video sources like sports and the news) have to be deinterlaced in some fashion. There's no simple answer as to which is better.Īny decent HDTV will inverse telecine any 1080i film source back to 1920x1080 progressive frames, then display it at the TV's native resolution.
