Title: Is There An High-def Patch For Dvd-x?
Post by: Foe-hammer on October 22, 2003, 02:27:00 PM

Yes- All that is required is a hex editing program, and replacing the hex values with the ones given:

For dvdx1 progressive patch:
Just replace C1 with D1


For dvdx2 progressive path:
Search for: 83 C8 02 C1 E0 04
Replace with: 83 C8 02 C1 E0 05

I actually have the progressive patch. But, progressive scan is not the same as high definition. Progressive scan is usually a definition of 480p. High defiition is 720p or 1080i.
Is it possible to edit the the dvds xbe file to output the HD resolutions?

I dont believe that the xbox hardware is capable of upconverting a dvd to HD, as a dvd is native 480p. unless its encoded in 720p or 1080i

go there :http://www.xbox-scene.com/tools/tools.php?page=xbexbx#newsitemEpFVplyppkIpAvOfNF

and d/l the progressive scan patcher. use it to patch msxboxdash.xbe , defualt.xbe(in dvdx, to play movie on ur HDTV)and all the .xbes if u wish to support HDTV. i tried it yesterday and it works. dont bother to d/l the individul patchers for msxboxdash or dvdx,they dont work !!! this one covers em all. the only downside is u have to have some knowladge of M$ dos,cuz its a dos based system.good luck

I've seen some DVDs that are mastered in HD. Do you think Those could be seen in HD with the progressive patch.

Right - These patches are only for to enable 480p.  720p and 1080i are not possible for dvd playback on the xbox, and i doubt they ever will be.

I hate to tell you but no you didn't Do they have hdtv dvd players and burners well yes in the consumer market no........


Sony I think is in the lead with this they have a blue disk coming out that can hold hdtv but you would need a whole new player...


You will not be able to purchase a hdtv and throw it in the xbox, or whatever other dvd player you got around the house...

ITS COMING BUT NO TIME SOON...

they have to make all thier money off of us with regular dvds first then they can rerelease all the movies in hdtv again

There are NO DVDs mastered in HD. Discs have been mastered from HD however and are usually cleaner. The current red laser MPEG2 system cannot accomadate the huge amount of data required by HD. Some Manufacturers want to introduce MPEG4 for DVD which will allow a poor mans version with extra embedded info for HD. They want it cause it uses a standard red laser and thus can be made in, funnily enough, the current DVD pressing plants they own. True HD does exists in Japan, from Panasonic, Pioneer and Sony. and I think the US now or very shortly. It uses a special disc and a blue laser. A blue laser has the advantage of being able to focus onto a much smaller pit/groove than red. A games console witha blue laser........................5 years and I am guessing. DVDs have been authored in PC resolutions for use with media players. T2 Ultimate is an example. It is not true HD but does look good.

I think I am right in saying that encoding graphics at HD resolutions takes up a lot less space than real video.

Broadcasters don't use DVDs to send us programming. They use something way better called a D1?? master tape or big HDD. You lucky people in the US do get real HD. You NBA is filmed in HD, editted, and transmitted in HD. A think a typical HD channel uses the space of six SD channels, which is why is ain't got many yet.

That's really interesting thanks for the info. What about that DVD player I put the link for up there. What does that really do then?

This DVD player

That DVD play basically takes the 480p source and upconverts to 1080i.  It then outputs a digital signal through the DVI interface.  It's clean but I'll tall you that even though it looks better (due to higher resolution) the source material is the same.  Like playing NES emulator on your xbox in 480p or one of Xport's emulators at higher res - it looks a lot better than the original just due to higher resolution output but keep in mind, it is still an original resolution.  Much better to display 1080i image at 1080i than a 480p image at 1080i.

The HD channels on TV all broadcast at either 720p or 1080i but the problems is that not all programing is in high resolution.  Like ESPNHD - outside of a few events (Monday Night Football) the programing is photographed with standard cameras.  Regarding movies I'm just not entirely sure they are doing anything other than taking a 480p source and broadcasting 1080i.  I'm sure the studios provide them with top notch copies but I am unsure whether the resolution is any higher.  Don't know but they don't look incredible - just noticably better and given film's theoretically unlimited resolution I'm pretty sure it's not a high res source they broadcast most of the time.

Any video format can be 'scaled' up or down to suit a specific requirement. Any 'fixed pixel' device such as an LCD or DLP pj has a built in scaler. You feed in a 720x480 pixel image from R1 DVD and it will scale that to whatever the resolution of the chipset on the pj is, usually 800x600, 1024x768 and more commonly 1280x720. Whatever you feed the pj with it will scle it up or down to suit. The reason why the Samsung as a scaler in it, is becasue they have chosen to fit an all digital DVI termination. If you feed a normal interlaced 480i or non interlaced 480p in to a pj with analogue connections the image resolution would be 640x480. It would then be scaled to fit the entired width of the chipset in the pj. Vertical scaling will differ with reference to aspect ratio. i.e. 1.78:1 (16:9) 1.85:1 etc. No pixel data regarding resolution is transferable by any* analogue interface used domestically. However use a DVI connection and the true source resolution will be transferred to the pj and it will indicate 720x480. Likewise with a PAL signal it would show 640x576 then 720x576. DVI is a handshaking connection and info is transfered between products to optimise the connection. DVI is also practically noiseless, so you get significantly better images.

* I have set up many connections using various cables etc including a 5 wire RGBHV connection and the full resolution was not realised until it was done digitally. This info is correct when using a Sim2 HT300Plus Pj and a TAG Mclaren DVD32R (DVI) and a TAG Mclaren AV192R.

Is there any way for the xbox to upsacel a signal to 1080i? It's not true HD but it should look better than the progressive patch, which, as far as I understand upscales the signal to 480p. And another question, are the games like the Matrix--which has a native resulotion of 1080i--in true HD? Does the xbox also have an upscaler, or are the games recorded in HD. Thanks, you guys have been a lot of help.

Matrix is true 1080i HD - it just has iffy graphics at a high resolution so it isn't overly impressive (think Pong in HD).

Xbox does not upconvert.  Most DVDs are recorded in 480p - this just lets the xbox output it in a progressive signal if you have component cables.  The xbox doesn't have nearly the juice to upscale a movie or even a recent game for that matter (I'd love to play my stuff in 1080i but most games are 480p and that's the way it is).

Well, the problem here is the source. We kow that XBOX could ouput video game in 1080i.

But ther no DVD in hight definition, not yet, and I will be Blueray or someting else, so the XBOX will not read those futur disk.  

Window Media player have some sample of HD clip on thei site, but it is 1080p. Even terminator 2 extrem edition have the movie in 1080P but it is encode and it is not been cracked yet, so we can't send it to XBOD Hard Drive.

So the only source of pure HDTV that could be test on XBOX in Satelite provider. I have a DVB-S card ( twinhan 1020) with can capture the mpg2 files that satelitte send directly to my hard drive. I can watch those files on My pc. I try to play them on XBOX but just got sound for 5 sec and no picture. I does not been that impossible to play, it just that the develooper don't have any HDTV source to play with. If somene want some sample I coul send them some HDTV mpeg2 files.


So there still hope!
