PS3 already upscales MPEG videos playing from XMB...??? - Blu-ray Forum

MozartMan · 03-04-2007, 03:49 AM

I just had this thought today.

I have Hitachi RP CRT HDTV with 1080i.

When I play SD DVD on PS3 my HDTV blinks several times then shows 408p on the screen and then DVD starts playing.

Now, when I play SD MPEG videos from internal HDD, MS, or data DVD or data BD-RE, my HDTV stays at 1080i.

Does this mean that PS3 doesn't upscale DVDs (yet) but upscales SD MPEG videos when playing from XMB?

Anybody has any thought/theory?

Yes, my TV upscales to 1080i when it gets 480i or 480p signal. When I press Info button on TV remote it shows what signal it is getting from the source.

In case with PS3 and SD DVDs it shows 480p, so, it is getting 480p out from PS3.

In case of SD MPEG files playing from XMB, my TV shows 1080i, so it is getting 1080i out from PS3.

And I don't run YDL on my PS3.

If he is actually playing video, I doubt that he is running YDL, at least not without some modifications.

I was running YDL, but I couldn't find a video player that would actually play anything.... Totem is CRAP! I use MPlayer on my FC-6 box, but when I tried to compile MPlayer on the PPC YDL install, it shot craps on me, so I switched the OS to FC-5, now the problem is that Sony hasn't given anyone but the YDL people the stinking drivers for the video and the audio (the bastards)

I just found a site with instructions to get a player working, I will see if it works tomorrow. Till then, does anyone have any idea for a good GUI based media player that is either:

A. Already compiled for the PPC verson of YDL
B. "Compile-able" under YDL for PPC?

Try VideoLAN, there should be various compiles to meet your needs.

kurt vidal · 03-04-2007, 11:25 AM

Mozartman, you are correct...the PS3 does NOT upscale std DVD's. I dont know about the mpegs.

thunderhawk · 03-04-2007, 01:14 PM

If it doesn't upscale DVD's, then why would it upscale MPEGs? It doesn't upscale, it's that simple.

However, there are rumors about a new firmware including FSAA image processing to upscale PS2 games - and probably DVD's too - to 720p.

thunderhawk,

I understand that theory.
But why my TV doesn't switch to 480p when playing SD videos from XMB and stays at 1080i?

I haven't tried ripped VOBs off DVDs then renamed MPEG yet. I've tried 480p MP4 files and it's played at 480p.

I'll have to try this later.

I've seen posts in other forums where people have renamed DVD vob files to mpg and played them at 1080i from the hard drive. I think this is probably right. I converted 640x480 motion jpeg movies from my digital camera to avc and they played at the default resolution of my monitor (1080i). By pressing the triangle button you can get to an option to show the movie at its original resolution.

javayoda · 03-04-2007, 04:14 PM

I should add my 640x480 avc files filled the screen while in 1080i mode (4:3 aspect so black bars on the sides). By pressing the triangle button, you can get an option that will display the video at it's original resolution while still in 1080i mode. In my case a small window in the center of a 1920x1080 screen.

I have no reason to doubt the behavior would be exactly the same for a 640x480 mpg (or a 720x480 DVD-sized mpg). That's scaling folks.

thunderhawk · 03-04-2007, 05:14 PM

What the... But is it scaling, or actually upconverting? And it's weird the PS3 doesn't see .MPG and .VOB files to be the same.

thunderhawk,

excuse my ignorance, but what is the difference between scaling and upconverting?

Deciazulado · 03-04-2007, 07:19 PM

he probably mean simple scaling (like photoshop's nearest neighbor) or advanced scaling (like bilinear, bicubic, spline) ...

jorg · 03-04-2007, 07:19 PM

i do not supose there are any dvds in mpeg format?

maby sony has alredy sneeked in upconverting?
and comfermation of this scalling with any one els with current frome ware or previous?

Erm, so DVD player that upconvert... Simply use bicubic smoother to upconvert...

Well, there are two different things imo:

Upscaling: Simply resizing an image, eg making it bigger without anything special
Upconverting: Resizing an image with mathematical techniques to limit quality loss

..? I'm not an expert btw.

MozartMan · 03-04-2007, 07:44 PM

Found this explanation on AVS forum about Upscaling vs Upconverting:

Quote:

Upscaling changes the resolution (480 to 720, etc.)

Upconverting changes the carrier signal (rca to component etc)
Upconverting can also change from interlaced to progressive but will not alter resolution (480i to 480p, etc.)

DVD players are upSCALING. They take the dvd signal and upscale it to whatever resolution you desire (720p, 1080i). DVD's are a digital signal to begin with and therefore DVD players do not upconvert anything (they don't change the carrier signal).

I guess it makes sense.

thunderhawk · 03-04-2007, 07:49 PM

I see. Thanks for the clarification MozartMan.

Question remain: does PS3 upscale? And, does quality go up or does it stay at the original resolution?
