Please explain the difference
 
Hi,

I'm sure this has already been covered, but I serached this news group
and didn't find anything. So, could someone please explain or point me
to a link or thread that will explain the following two questions:

1) what is the difference between progressive scan dvd players and
upconverter dvd players? And which one is better?

2) I was really excited to see the new Sony 1080 resolution wide screen
(forgot model number) but my jaw dropped when I saw the picture. But I
read on this group that it is not "true native 1080" resolution and
that we will have to wait for a true native 1080 resolution set to be
released in the near future. Please explain what "true native 1080" is
vs. the 1080 resolution that these new sets have.

Thanks and sorry if you have already discussed this a thousand times,
just point me to the thread if you don't feel like answering again --
cheers!

A progressive scan dvd player will output a 720x480 (60hz)progressive image.
An upconverting dvd player will upconvert the 720x480P to either 720P
(1280x720P) or 1080I (1920x1080 interlaced-30hz). If you have a digital
display (lcd-dlp) upconverting dvd players can be of some use since they
usually have better scalers than the tv has.

2)Probably refers to the fact that the tv can only accept a 1080I feed, and
will use its internal de-interlacer to display a 1080P image. The tv cannot
accept a native 1080P feed. I've read of certain 2006 model dlps will accept
a 1080P feed, but I'm not sure about Sony. You should go take a look at the
display forums over at www.avsforums.com There's a LOT of info over there.

Upconverting DVD players are progress scan dvd players - but they convert a
480P signal to a 720P or 1080i signal. They basically add resolution to the
picture. Whether or not it makes a difference is debatable...


Progressive scan means that each line in the display is refreshed in
order from top to bottom to create each frame. Interlaced means that
first the odd lines are refreshed and then the even lines are
refreshed. Progressive generally gives a smoother display.

Upconversion does not add resolution. It calculates and interpolates
between the number of lines in the signal to create more lines. There
is no additional information (or resolution) but, with a high
resolution display, the effect is to smooth the transitions and make a
more appealing picture.

And of course, to be factored into the discussion is the present, and
likely continuing, scarcity of 1080p source material, which may render
a set's 1080p capabilities moot for most viewers most of the time.
