Many of these component inputs are not of sufficient bandwidth to accept a progressive scan signal. I have two such TVs, a 14in Toshiba and a 31in JVC. I use DVD players on them in interlace mode and find the picture quality more than acceptable. Of the video input choices available on these TVs, component is still the best, even in interlace. Your regular component input fits this category. Your "HD" component input has expanded bandwidth to accept a 525p PAL signal generated by a DVD player. It might also, as its label implies, accept a genuine HDTV (720p or higher) signal. My question is why not use the DVD player in progressive on your HD component input and be happy? Or do you need that input for something else? |

New member Username: JonnycageChennai, Tamilnadu India Post Number: 3 Registered: Jul-07 | Thanks John for ur usefull comments,i highly aprreciate it.one thing i dicovered since i posted on the forum is that,the picture quality while i use the component in, in interlaced mode is much better than what i got while using HD ypbpr in progressive mode,dont know how that happens.and one more thing, i could watch movies while using component in in progressive scan,but that happened all of a sudden,but after i stop playback and restart it later,the screen goes blank,i have to go back to interlaced mode to watch further,its mysterious. and my tv has progressive scan mode,is it sufficient?,am i getting what i would get while i use the progressive mode on my dvd player,i couldnt find a difference.as u asked,im just happy with what i get,the thing is that i just wanted to benchmark my new tv and hometheatre and find the best settings.thanks. |

As far as NTSC is concerned, progressive scan is usually preferable with most TV/DVD player combinations. The difference between interlace scan and progressive scan is not dramatic. Progressive usually yields a smoother more movie-like image which most people perceive as more agreeable--even sharper--than the same movie sequence in interlace mode. But this changes when the PAL system has to process an incoming DVD signal from a movie shot at 24 frames per second. That has to be reconciled by a 100Hz TV that has become the norm on modern PAL-based TVs. There is an interesting article on this subject that concludes: So, as we have seen, progressive scan seems to offer little for PAL. Plus, a word of warning: some progressive scan devices actually reduce the quality of PAL. How? By taking a PAL signal and turning it into progressive scan NTSC. So you lose PAL's higher resolution and get in return progressive scan NTSC's subtle jerkiness. Hmmm. Not a good choice. So the conclusion the progressive is better than interlace does not necessarily apply to PAL-based video equipment reproducing movies via DVD. I stress the movie part here because using progressive scan when viewing video shot originally in PAL would be preferable. http://www.hifi-writer.com/he/progscan/progscan.htm I can't explain what is happening with the blank screen after playback interruption. There are bits of playback information ("flags") the TV needs to see from the DVD for proper playback. It is possible that the TV is missing these flags for progressive mode to continue. I would be interested to know if this blank screen happens at the beginning of a chapter instead of a random point in the middle of one. All this is academic because I think it is obvious you should stick with interlace playback with this TV. That could change should you find yourself with a non-CRT fixed pixel TV in the future. |
