Andre Vrignaud, that's who.  He asked the question.  
Bruce didn't call Andre and say, "Hey, I've got some hot opinions about Sony's shitty scaler.  Wanna hear 'em?"
Vrignaud got the interview, and asked the questions.  Bruce answered with his honest opinion.


Andre just put a question, it's the way journalists are working.
The answer is the mistake.
A better one (in a better world) should have said something like "They have their scaler, that's not so impressive to me, and we have ours".

I have said it before:

<b>
-it's a horizontal *stretcher* ONLY
-REQUIRES ANAMORPHIC [squashed] picture to work [like this:]

(IMG:http://i138.photobucket.com/albums/q262/anonim1979/oblivionanamorphicmaly2razem.jpg)
http://en.wikipedia.org/wiki/Anamorphic
-only 3 resolution supported 960x1080 1440x1080 1600x1080
-at least 10% more costly than 720p
-REQUIES GAME ENGINES REWRITE to work with older and new titles
-ENGINE MUST have 2 DIFFERENT modes suported - for anamorphic output AND normal output [rest of resolutions]


-it works by doubling [for 960]/puting 1 extra pixel for every 3 pixels [1440]/puting 1 extra pixel for every 4 pixels [1600]

-WON'T WORK with PS1 / PS2 games
</b>


It does NOT upscale to 1080 - frame is already in 1080.

for example 960x1080

sending lines 1,2,3,4,itd from 1080

abcdefghijk....
abcdefghijk....
abcdefghijk....
abcdefghijk....

it simply addas pixels:

aabbccddeeffgghhiijjkk....
aabbccddeeffgghhiijjkk....
aabbccddeeffgghhiijjkk....
aabbccddeeffgghhiijjkk....

X360 scaler works in all directions, it's similar to analog knobs on CRT monitor stretching picture.

PS3 uses TRICK - uses probably changed timings in output - puting extra pixels
like somebody said it's a trick similar to that used on PS2:
QUOTE

Uh, isn't this the same thing that the PS2 did when it went into "16:9" mode in 480p? They didn't actually increase the output resolution... they just, umm, squished the image so that it looked correct on a 16:9 display. :|

"PS3 uses TRICK - uses probably changed timings in output - puting extra pixels

You cannot do something like this over a digital link.
And we're talking about interpolation so it should be

abcdef
a(a+b/2)b(b+c/2)c(c+d/2)d(d+e/2)e(e+f/2)f (<-- Horizontally the XBox360 should bring out something like this too)

On the other hand you're right, vertically the frame is already at the output resolution, this is the reason they called it Horizontal Scaler instead of "Horizontal and Vertical Scaler", so what ?
Having a full vertical resolution you can probably get more details on a single frame, that's nothing bad.

And, by the way, there are a lot of differences between analog and digital when it comes to high resolution, high refresh rate and digital displays (like plasma or LCD), you can try to figure out understanding why a Digital->Digital connector is better than Digital (Video card)->Analog (scaler/connector)->Digital (Display).


You can make this claim all you want, and in theory it makes sense, but in the real world you can't see any difference in PQ between the 360 and PS3.  I have both systems set to 1080p and I have yet to notice any difference. In fact, the 360 games currently look better due to the system being out on the market longer.

Who gave MS the right to criticize Sony for the choice ?


Yeah because Sony didn't deserve any of this, nor did they talk trash first. Sony never lies or overpromises anything, they're as innocent as a puppy. AND the PS3 is WAY BETTER than the 360, especially Mobile Suit Gundam and Ridge Racer 7. People at Microsoft are big fat meanies.
