Title: Xbox 360 Hd Formats - Update
Post by: thax on June 23, 2005, 04:12:00 PM
From Rockster on Beyond3D Forums, who seems to have some additional information from somewhere:
QUOTE
According to the TCR's devs only need to target 720p. The outboard display chip is responsible for scaling the image. It can scale up to 1080i or down to 480i/p. MS made this decision in order to support ALL HDTV's without requiring specific developer support for each display mode, as was the case with XBox 1. Many older HD displays are limited to supporting only 1080i or only 720p.

Because it does its scaling in the analog domain, this display chip is incapable of digital outputs like DVI/HDMI or supporting 1080p. It was designed by MS's WebTV group. Right now it is limited to composite, s-video, component, and vga. The chip can be re-engineered and changed later since it is seperate from Xenos to support digital out, but that could create consumer confusion as to which XBox units do what.

TCR means Test Condition Requirements I think.

If this is true then it means that all games will be rendered in 720p and up or downscaled to all other resolutions.

this is both good and bad news...

bad
-we wont be getting true resolution outside of 720p on games were developers are lazy
-people with 4:3 TVs might be playing games with lazy developers in letterbox
-no digital out (though due to the nature of the chip it wouldn't matter because it's an analog signal anyway)

good
-Xbox games running through the BC emulator might get up-scaled
-at least all games will be running in True HD 720p

Well, in a way its good news to know that I'll never have to worry about games that support 720p but not 1080i (my TV only supports 1080i...).

However just as twisted mentioned, developers will probably just develop for 720p which means most -if not all- of the games I'll be playing in 1080i will be upconverted. This isn't necessarily a bad thing since most people won't notice the difference but still...

This really bothers me and always has. Considering that all HDTV's now come with either HDMI or DVI, I dont understand why M$ is not supporting it. I don't consider an analog signal as HD, it needs to be digital. There is a very big difference between components and HDMI/DVI when in 720p or 1080i in my opinion. dry.gif

im kinda confused about that .. my tv supports only 1080i and 480p/i..
so the game itself will convert 720p to 1080i?. or is it up to the tv to do the converting?  i hope its not the tv cause mine wont do it ..

My understanding is that all games will be rendered at 1280x720 then the webtv chip will convert that resolution to whatever mode your television supports, whether it is 480i/p, 720p or 1080i. Earlier MS had stated that they would encourage developers to support 4x3 mode, and most kids games will probably support this mode.

This means that the average person doesn't need to do anything, the games will work on all televisions without problems or knowledge of what is happening behind the scenes. It is probably a good thing that the xbox chip does the upscaling / downscaling because I have heard of televisions that do a horrible job of doing this. I bet that the 720p to 1080i output will look real nice.

i hope youre right.. im sure the 360 will look fantastic in 480p as well, but i'm hoping all of us schmuks without 720p will be able to play in 1080i.

Guys, MS said that the games also support a native 1080i. I've posted this in another thread, but I'm sure I remember TwistedSymphony seeing it.

Opps my bad, I've jsut read 'THE' article and it says that the xbox360 will most likely scale 720p up to 1080i Of course, it will upconvert the resolution better than your tv wouldm so I guess we should be fine.

I doubt that gaem devs or MS will ignor 1080i though. I meant, it's just not practical enough to just upconvert 720p to 1080i if the upconversion will be low quality. If it is a good upconversion, then I will be happy, but a native 1080i would be alot better if it provides better quality over what the upconversion looks like.

I should hope it's a high quality conversion... considering most people who will buy next gen consoles will not have HDTVs most if not all of what they see will be filtered through the converter.

As for not supporting digital... it really depends on your display. As far as I'm concerned CRT and Plasma based displays don't benefit from a digital signal the same way LCD and DLP displays do.

MS went after component because ALL HDTVs support component or some derivative of that... only newer displays support DVI or HDMI. I have 3 projectors only 1 of them has a DVI port, though all three support component, none of them have HDMI.

I understand MS's logic in that component covers everybody, they're not making their system very future-proof by passing up digital video.

Post by: crustyteacup on July 05, 2005, 03:03:00 PM
i don't think it was built with future proof in mind. the 360 will have a shelf life of around 5 years, by that time i doubt most of the population will have hdtv's anyway. having it render at hdtv resolutions is only a little added bonus because its only the few that can take advantage of it. theres no point in making everybody pay a premium because a small percentage of people want it at 1080i without upscaling, the same can be said of the remote control for the xbox.

Post by: nj12nets on July 05, 2005, 03:50:00 PM

Just for completeness the rumour of the on-the-fly conversion inside the xbox is all but confirmed with the recent interview on Paul Thurrott's Supersite.

Jeff: The first real wave of revolution that we think Xbox 360 is going to bring to gaming worldwide is high definition gaming. You heard this a lot at E3. If you walked out of E3 without hearing high-def, it would be a miracle.

Hi-def to us is, partly, about pixels on the screen. Every Xbox 360 game is going to be 720p minimum, high-def resolution, 16 x 9 aspect ratio. It will look great on both high-def and standard-def televisions because we built in enough graphics horsepower that Xbox 360 in real time can scale down high-def images to standard def.

Paul: Is it scaling down to the same aspect ratio? Or is it scaling it down to 4:3?

Jeff: We will actually give the game developers a choice. They can either have the Xbox 360 automatically crop or scale. Or, they can render a different aspect ratio scene of their game if they want to. Or, a game developer can say, "let the user choose." And there will actually be a setting in Xbox 360 to tell the box what it should do. And game developers can just hand it over to the box to decide what's best from a user's perspective.


What this means for most games if you have a 4:3 television you will either see letterbox or be missing the left and/or right edges of the screen. My guess is the cropping will be the mode of choice as people will complain about letterbox.

this is good news because i bought my hdtv not knowing that there was a difference in resolutions.  i just assumed there was only standard and "hi-def".  my 47" widescreen does not do 720p.  only 1080i/480i/480p.  and i agree about the difference between dvi connections and component cables.  a considerable difference.

Post by: c00ly on July 12, 2005, 05:10:00 PM
that doesnt make sence that it would crop the picture from 16:9 to 4:3 because something like a HUD wouldn't work at all, because the most important info on a HUD is always in the corners.

yes but those games are coded for widescreen by the devs, if the console will simply chops it into 4:3 it wont work because valuable info (HUD's, health, etc.)will be lost.

i think in the end m$ plan can best be summed up by the saying "penny wise, ppound foulish"   they are gunna end up running themselves into a wall when i comes to marketing in the long term.   Not for the fact that the up scale, which is good and bad.  Rather for the fact that they don't include digital outs.  I have an hd tv and i can personly testify that moving from component out to dvi was worth it.  i can only imagine sony's marketing campaign about how they are the only true digital experience and how they fully suport the hd experience..this will especially become evident in later year when digital will be incresinly important.

also on the subject of the up scalling and down scalling, its pretty smart.  Think of how much easier it will be for developers.  The only downside is for ppl with 4:3 tv's.  I wish it have a menu fuction to change from 1080i to 720p  because at some point i'd if ur tv has both u'd rather have the progresive and not the up scaled interleaced shit

on my HDTV there is only a slight difference in picture quality between DVI and Component when I connect my comcast HDTV box.  Mine is a CRT HDTV, that could be why.  I really dont care if they use component or dvi/hdmi, both look great to me.

Post by: Carlo210 on July 20, 2005, 02:29:00 PM
If you guys want, you can check out the Faqs to answer your questions.

I've had my mind set on a 27" Sanyo Hdtv for a while now simply because I do not mind letterboxing bars.
Then lately I've decided a progressive choice would be best. So I started looking at some flat panelt lcds around 15-30", but the response times are just fu^king horrible. The only high quality flat panels that suits my style (i hate lagging and ghosting) are the DLPS which are  around 50" and above my price range incredibly, so I'm stuck in a rut.

I don't want to spend a fortune on a flat panel, leaving me with a smaller size, and I don't want a cheesy classic lcd fuzzy ghosting display, so that leaves me with what, crts? But I want a progressive resolution. ARGH

People still go on that flat panels are the god of tv's, but the quality and technology in them stiill havent, personally, caught up to my likes. I wan't a sharp crisp picture when in action and motion filled scenes an sequences, but I haven't found a display like that yet in my price range. God, are these things expensive.
1500$ for a 30" hd Lcd display with clear artifacting or a 30" hd Crt display with a crisp, quick, and sharp picture.

For gaming, since that is what my new bedroom television will be for, I need something that can stay crisp and clear, not full of lcd artifacts.

It's really been pissing me off. I would be fine with a crt hd display, but all this bashing of the 1080i resolution forces me to go towards the expensive artifacting world of 30" lcd's just for 720p.

Any suggestions?

By the way, my price range is 0$-800$ Canadian, roughly.

To get the xbox360 near release, or even a month after, I will be forced to hold on my tv purchase and use my xbox360 on my 20 year old den tv. After I make enough money, i can get a hd tv for my bedroom within my own time, but I still dont want to blow over 1k canadian on a tv. I'm a teenager who wants an hd tv in my room that can display 720p and is more than 25" (widescreen size).

Yeah man, I personally would go for the crt.  I got a crt and a lcd both hd about two months back.  The lcd is great for movies, but the crt is better for games, no artifacting at all on the crt.  The lcd does artifact and does have progressive, but for my money, the native res of 1080i and interlaced is good enough for me.  The differences between the two are minute at best.  I hear people all the time complaining about progressive and interlaced, which is better.   Having both, I can assure you that the 1080i is great and hey, it's cheaper.  Only thing is, the tv is a 4:3 but my tv does have vertical compression so it doesn't use the black area to draw lines of resolution and squeazes the res in a smaller space.  Awesome.

Nice, a 19" monitor. LCD? If it's a 19" LCD then I'm guessing it doesn't have a great refesh rate (maybe near 16ms).
If it's a crt, then what kind?
Dell? I've heard many problems about Dell monitors, alot of customer disatisfaction.
What kind of monitor?

Both my pc monitors are sony and both are crt.  I tend to rag on sony alot, but these crt's are great.  We got alot of lcd's in the server room where I work, we play games on them also, the refresh on those are 8ms.  They are 17" and all but two are sony's.  The other two is a regular samsung 17" and the other is the 26" monster of a samsung that costs like $1500 I think that M$ is using for the xbox360 kiosks.  They are pretty good, and my boss said I can have one if I want one.  Thats the 17" lcd of course, wish he was talking about the sammy, but hey free is free.  One of the Sony's I got is from work, the 19" I'm using right now to write this reply and I got this one brand new because the IT guy ordered too many about a year back.
Title: Xbox 360 Hd Formats - Update
Post by: aetius on August 01, 2005, 06:20:00 PM
Just wanted to correct a few things people have said in this thread:

1. Despite what everyone keeps saying about the "digital switchover," for most people this will mean nothing at all. The switchover that is being required is only of broadcasting and receiving. Therefore, everyone who gets their TV through cable and satellite will not see anything different and can continue to use the TVs they've always used. Only those who get their channels over the air will need new tuners and most new HDTV's include these. In fact, there are a few non-HD sets that are starting to include them. But since this switchoff is currently in the 2008-9 timeframe, most manufacturers don't bother. However, seeing this now, I believe that by the time the switchover happens all new TVs will have started coming with a digital tuner for a year or so.

2. Also, many 1080i TV's in actuality do a a pseudo-upscaling from 720p. Since these are mainly CRT's, they will convert 720p down to two slightly offset 1980x540p frames and then alternate these to get 1080i. The worst part about this is that some don't even bother with changing the horizontal resolution to 1980 and just leave it at 1280x540. Thankfully, many CRT's are good at compensating for odd resolutions and weird conditions so most people don't notice but lets hope that the 360 scaler does a real upscale and doesn't cheap out using the above method.

3. Also, for those looking for a good, cheap HDTV Samsung makes several units in the 27"-34" range that start as low as $449 retail and can be found as low as $350 if you can find somewhere to sell it to you near cost. The Samsung 2765 gives good image quality for the price and can handle 480p and 1080i but NOT 720p. For that you're looking around $600 for the 26" widescreen model. There are other good sets that have these features but they tend to cost more. Several people around the AVS forums have mentioned an extremely cheap TV based on the same tube at Wal-Mart under a different brand name.

Anyway, just wanted to clear up those things.

Peace
