    What is progressive scan ? Is it only for projection units or can it be used for normal tv's ?

    Is the DVD picture quality alot better on a 32" widescreen tv ?

    cheers

    Very few TV's can do or handle progressive scan.

    Here's a good explanation of progressive scan for NTSC which uses 3:2 pulldown. PAL uses 2:2 pulldown. You will soon see what I mean ;)

    Either the dvd player has progressive scan output and the tv can handle this or the tv does the job. It depends on what equipment you have.

    Frankly, I do not know of a 32" tv that can handle progressive scan.

    Can anyone help us out?

    I'm disappointed that Jonny and Sly didn't know that these forums are the official community area of The Progressive Scan and Video Processing website.
    There is also at least one article on the subject at one of the other related websites - What Video & TV.
    You can find a complete explanation there.
    I believe that HDTVs can do progressive scan. It's just that they aren't available in the UK. Oh and there are no HDTV broadcasts in the UK, either.
    To get progressive scan in the UK, you are really looking at using a projector.

    Can I also add that 2:3 and 2:2 pulldown is just a method of getting 24 film frames in to an interlaced video signal at 60 and 50 Hz repectively. It doesn't relate to progressive display of video based material.

    Devices which can recognise the 2:3 or 2:2 sequence of original film based material will, generally, do a better job at creating a good prOgressive image than those that cannot.

    Plasma screens are good devices to use with progressive scan output DVD's or scalers as are projectors as Spectre mentions.

    For a 32" direct view TV in the UK that can accept a progressive scan input signal you'd probably be looking at a Loewe with optional VGA input board. You'd then need to get a device to transcode YPrPb to RGBHV. It would also only work on NTSC material as PAL progressive would have too high a bandwidth for the TV...

    Hope this is some use.

    I think you'll find that they both are able to de-interlace an incoming signal but that neither will accept a de-interlaced input signal. I'd also be very surprised if either had particularily good de-interlacing built in....ie they will not have 2:3 or 2:2 recognition for film based software resulting in lots of artifacts...

    Spectre, sorry for disappointing you. As you can see I'm new to this forum and need to work my way through this jungle of information.

    How about a warm welcome ? ;)
