DVD Upconversion:Noticeable difference in picture? or selling gimmick?
 

I have a samsung LNT4565 model. Previously I watched dvds on my older
toshiba sh400 (dvd player & free basic tivo) player (component). For
Christmas I got a sony ns77h, around $85 (hdmi). The sony is outstanding.
Could be combination of hdmi and better upconverter, but it is better.

I have a 42 plasma, so I was wondering if I should buy a upconversion
DVD player. Will I actually notice the difference or is it just a
selling gimmick. Any samples on the web showing the difference, or
would that not be possible to do, we all have different type of
monitors/ lcd.
Thanks.

This may only prove that the upconversion in your display is not
as good as some others.

One. The one I watch. 1080 into 1080 will look better than 480 into

On how many different TV models have you tested your ability to
discern a difference?

Huh? Tv only displays the signal sent into it. That's why s video
Dish looks like crap compared to OTA HD. The signal needs to be
maximized BEFORE going to TV. Upconversion is great. I see no need
to buy bluray for a long long time as picture is comparable

With the possible exception of the rapidly disappearing CRT HDTVs, all
digital TVs must convert any accepted input to the TVs native
resolution. Depending on the native resolution of the TV and the
incoming signal, the conversion could involve up conversion or down
conversion. Since all HDTVs have resolutions that exceed DVD
resolution, all HDTVs must up convert the output of standard DVD
players and any other SD sources.

I suspect that "s video Dish looks like crap compared to OTA HD"
because one is relatively highly compressed SD fed to the TV via an
analog SD-only s video connection, while the other is relatively
lightly compressed HD. The degree of "crapiness" depends on the
amount of compression in the Dish feed and the ability of the TV to
upconvert an analog SD signal.

I realize that some HDTVs have a "1:1" setting that displays inputs
without scaling (at least in theory). Using the "1:1" setting can be
quite enlightening. That "s video" signal will be just a small
rectangle in the center of a big black screen.

So, if "upconversion is great" for you, then (probably) you have a
good external upconverter and your TV's native upconverting is
relatively poor. In a case like yours, external upconverting makes
good sense. However, a real HD source, such as a Blu-Ray disk, should
always look better than the equivalent upconverted SD source; there is
simply more detail to display. How much of the extra detail you can
see depends on the quality of your TV, how large the TV is, and how
far you sit from the TV (and how good your eyes are).

Whether or not you want to pay for the added detail, as always,
remains your perogative. Some are willing to pony up the dollars
today. Some will wait for tomorrow. And some may never find it
necessary.

Enjoy,

One. The one I watch. 1080 into 1080 will look better than 480 into
1080

This is not valid as a general statement, when you anyway only have a
"480 source" to begin with. Upsampling can be done with varying
quality and depending also on the type of material. You might also
have the same type of circuits built into the TV as the upsampling DVD
player has.

The drawback with external upscaling is that many TV sets crops the
picture somewhat anyway and scales the signal one more time.
Even with sets that can display an incoming native resolution pixel
for pixel, many sources don't provide undisturbed picture content
right up to the edge. For that reason it might be better to transfer
the "material native signal" to the TV, than scale twice.

But of course you should use the combination that gives the best
results, but it is not given that an external upscaler gives the best
result.

What are you talking about? The TV only displays the signal sent to
it. When I press the "info" button it shows the input resolution.
With dish and s video it shows 480 with component dvd it says 480.
With OTA its 720p or 1080i. The upconconvert dvd shows 1080 or 720.
This is a plasma hdtv. There is no "automatic" conversion on any hdtv
I've seen and used- Hitachi, Sony, Panasonic- they show what goes in
and that's it!

No, your TV displays the information what type of input signal it
receives, but your plasma display has a fixed number of physical
pixels.

It scales the incoming picture to fill those pixels. Exactly how it
does this scaling varies with the TV model (and scaling circuits) but
it is never a simple repeat of input pixels. So the scaling performed
by your DVD player is of the same principle the TV does, but since the
algorithms might be different the resulting quality also varies.

Yes but there is no automatic upconversion as one poster stated. Of
course the tv creates a picture based on input but a 480 picture is
stil 480 despite the pixels used,

You clearly do not understand.

The signal on DVD is 480i. You can watch it by:

+----------------+
+----------------+ | |
| upconverting | | HD TV set |
| DVD Player |----1080 signal----| |
+----------------+ +----------------+
Set shows 1080, because that
is what it was fed.

or


+----------------+
+----------------+ | |
| standard | | HD TV set |
| DVD Player |----480i signal----| |
+----------------+ +----------------+
Set shows 480, because that
is what it was fed.


In the first case the upconversion from 480 was done in the
DVD player, in the second case, the upconversion was done in the
TV.

In *BOTH* cases the orignal signal is 480i, because that is what is
on he DVD.


The plasma set has a fixed number of pixels on the screen. If the
signal sent doesn't match, it silently converts it to match -- automatically.
