how to gain HD through a DVD player.

[michcio]

hi!

I have resently bought a 44' (I think) LCD HD TV and I wonder if it's possible to gain HD through a DVD player. I have connected my DVD with HDMI cabel and my DVD also have an USB input. So say I got a HD .avi file on a USB. Will I gain the best quality while input into my DVD?

cheers

That is not likely.

You'll have to check the resolutions it supports. Chances are it only supports standard def video files.

You may get lucky and it will support slightly above sd but probably not.

You will get them upconverted though with your hdmi connection.

here's what I found about my DVD's HDMI settnings:

(the blue marked settning are thoes I'm using)

Resolutions:
480i
480p (720)
720p
1080l
576i (720)
720p (50 Hz)
1080i (50Hz)

HDCP:
ON/OFF

Audio Source:
Spdif/12S

HDMI SRC:
ON/OFF

HDMI/DVI:
HDMI/DVI


how do you mean "You will get them upconverted though with your hdmi connection." the resolutions?

I believe what you are reading are the output resolutions. That doesn't necessarily mean that it will take them as INPUT resolutions.

All you have to do is try a sample file of that resolution and see if it works.

[michcio]

what INPUT resolution shall I try with then?

when does an .avi file become a HD AVI ?

[ntscuser]

what INPUT resolution shall I try with then?

Whatever your source file happens to be. I presume it is greater than 720x576?

[michcio]

from GSpot I can see my .avi is 624 x 352 :O but in the .avi's name it's written it should be HD

[ntscuser]

from GSpot I can see my .avi is 624 x 352 :O

That's not HD. It needs to be greater than 720x576

[michcio]

where can I find a HD avi that I can test then? :P

[michcio]

ah so 720p is HD as well? 720p = 720x1280 right? but why does every 720p clip seem to be in .mkv format? I don't think my DVD will read that format. Can I convert it to avi and not loose the HD quality? I remember I had convertet mkv to avi once and the avi quality became really bad.

There are quite a few HD test clips available in avi format but you may have to do a bit of searching for them.

[michcio]

ah ok! but are there not HD pictures as well then? I have tried to first open a HD (1080p) picture on my computer and the details are very good. But then when I open the same picture through my DVD I get much wors quality. :S

Btw I don't understand the differance if I choose 1080i or 1080l on my DVD-player

Judging by the list you posted 1080i is 50Hz and 1080I is 60Hz (both interlaced). I suspect also that the 1080I output setting is restricted to 480 line input sources and the 1080i setting is restricted to 576 line input sources. The final resolution will only be as good as the input source regardless of how many lines it's converted to.

What you are asking is akin to "Can my car go from 0 to 60 mph in under 4 seconds?". If your car could do this you would already know because you specifically sought out that feature before you bought it. There are only a small number of DVD players that can play any file over 720x576. If your player supported this you would already know because you would have made sure it was supported before buying it.

[michcio]

thanks for all your answers. I have now tested a 1080p file on my DVD (resolution: 1920 x 1072) and it doesn't work. There accured an error message: "DVD-player doesn't support this resolution" but it's kind of weird because it has a 1080i settning.

I also start wondering. Why should a DVD player need a HDMI input if I cannot play HD clips on it.

1080P is twice the resolution of 1080i although the difference isn't that obvious to the naked eye. Apart from that the settings you mention are for output not for input.

If you actually tell us what your DVD players - make/model - then someone will be able to confirm exactly what it is capable of. However the chances are very high indeed that it is a standard DVD player, capable of playing back only standard definition material, but with a cheap upscaler thrown in to upscale the image to HD resolutions. If you TV is a good one then you may find it can upscale just as well, if not better, than the player.

But make and model of player will tell us a lot more than this mindless guess work

[michcio]

yeah sure they are for output. But how can I know what (input) resolutions my DVD player supports then? So if you are saying that 1080p is "better" then 1080i then if I have 720p as my input my DVD should read that without any problem??

I'd be staggered if your DVD player could support any input higher than 576i.

ok sry here is my mark/model of my DVD-player:

SALORA
MODEL NO: SDS-4311

and my TV:

LG:
42LG5000-ZA

[michcio]

I'd be staggered if your DVD player could support any input higher than 576i.

then why does my player have so high output resolutions? to convert a movie into a higher one that fits into my TV exaclty?

Yes.

[michcio]

ok =) and why does it need the HDMI cabel? if it only can play resolutions up to 576i like you said wouldn't it be cheaper to just buy a SCART instead of my HDMI? wouldn't I get exactly the same results with a SCART?

Scart doesn't support resolutions higher than 576i. It's also analogue whereas HDMI is digital.

[yoda313]

Also HDMI is needed for any hdcp material - but that is generally for bluray source materail - fyi.

The chipset in the DVD player interpolates (guesses) a 1920x1080i frame from every 720x576i/p frame. The result does have 1920x1080 estimated pixels so requires an HD connection (HDMI or component).

What hasn't been mentioned is most players will inhibit upscale from commercial DVD discs. Instead they revert settings to 576i or 576p.

There are players that will play some HD files and there are Blu-Ray HD players. Both types usually cost of well over $200US. If you didn't pay that much, it is doubtful your player will go above 720x576p source.

Upscaling DVD players can upscale the image better than some older HDTVs. Most newer HDTVs have upscalers as good or better than the inexpensive DVD players.

Normal upscaling DVD players have MPEG2 decoders only strong enough to decode standard definition DVD (720x480 at 30 fps, or 720x576 at 25 fps). Divx certified players use MPEG4 decoder chips also limited to those resolutions. They then have video chips that upscale the SD image as it's output to the HDTV.

If you want to play high definition material you need an HD media player like a Western Digital TV HD Media Player or a Popcorn Hour. There are several threads here about those players.

[michcio]

the 720x576i/p .avi clips are of course not in HD quality :P so I can't gain HD through my DVD player have to buy blue-ray for HD then?

[jagabo]

If you want to play Blu-ray discs you'll need a Blu-ray player. If you have other HD sources you may be able to use one of the players I mentioned earlier.
