"HD TV with spatial scalability for 720p (1280x720 pixels) at 50 fps with 1080p (1280x1080 pxels) at 50 fps enhancement"

Come on you promised...

Ok, I think we can agree that the standards for resolutions are pretty muddy as to what is official terminology and what is not. Computer resolutions are extremely standardized, whereas differing standards for each countries broadcast system requires different standards for TVs. If I say this is a SXGA monitor, there's no question as to what the native resolution of that monitor is.

I also think we can all agree that 1080p is generally accepted by most people to mean a resolution of 1920x1080. Calling GT5 Prologue a 1080p game is (IMO) technically correct, but is potentially misleading to consumers. BUT, it's no different (again, IMO) from saying this or that game "supports" 1080p. You wouldn't believe how many people think Halo 3 runs at 1080p because "it says so on the back of box."

And that's basically the last thing I'll say in this thread.

And before anyone here does claim that Halo 3 runs at 1080p, no it does not. It outputs a 1080p image, it upscales to a 1080p image, but it does not run or render at 1080p.

"HD TV with spatial scalability for 720p (1280x720 pixels) at 50 fps with 1080p (1280x1080 pixels) at 50 fps enhancement"

Uh, "scalability"? Pretty vague, Mike. You found one extremely vague document focused on scalability, which doesn't have a damned thing to do with what we're talking about here.

You're grasping at straws. 

*confused...

The logo just says "HD1080" with no "P" and then you quote "1080p Compatible"?

You're right, those companies don't lie, they just muddle the facts.

1080p = 1920x1080
HD1080 = 1280 x 1080

Jeez that's a standards organisation clearly referring to 1280 x 1080 as 1080p.

You asked for just one source and then ask for more?

Gebx, the HDMI port was listed as "1080p compatible".

*rolls eyes*

@ gebx

You keep coming up with anedoctal evidence of companies referring to1280x1080 as 1080p. I have yet to see you provide one reliable source that actually defines that resolution as being 1080p and why it's considered that resolution. Why do none of the major sources refer to this as a valid 1080p resolution? Why do you have to keep digging up obscure scalability articles and video submittal guidelines to back up your argument?

@MikeB way to go ahead and site Scalable Video Coding as a source. That is not the resolution that is meant to show on the screen instead it is the accepted resolution for reduced bit streams(aka data rates). It would make sense that Sony would develop a 1080P game using this standard just to reduce the load on the PS3 and still give a devent looking output but it is not 1080P but a substandard.

Scalable video coding (SVC) was developed by the Joint Video Team (JVT) of ISO/IEC MPEG &

ITU-T VCEG in a standardization project completed in October 2007. The SVC enhancement of

the AVC core design includes the specification of three scalable profiles (the Scalable Baseline,

Scalable High, and Scalable High Intra profiles). It enables the construction of SVC bitstreams that

contain reduced bit rate substreams. The substreams can be extracted from the complete bitstream,

thereby providing scalability in terms of bit rate, decoding complexity, and frame rate, spatial

resolution, or quality. In typical cases, one or more of the substreams of the SVC bitstream will be

fully compatible with ordinary AVC decoders. Frame rate scalability (also known as temporal

scalability) or spatial scalability refers to the presence of a substream with a lower sampling rate

than the overall bitstream in terms of time or spatial resolution. Quality scalability refers to the

presence of a substream with the same sampling rate as the parent SVC stream, but having a lower

bit rate with a correspondingly lower quality.

The verification tests were conducted using conditions suitable for a range of possible application

scenarios for progressive video, including

352x288 pixels) at 30 frames per second (fps) video, and spatial scalability for 640x352

pixels at 60 fps video with an enhancement substream for 1280x704 pixels at 60 fps;

pixels) format at 25 fps video, and spatial scalability for QVGA at 12.5 fps with an

enhancement substream for VGA (640x480 pixels) at 25 fps enhancement;

pixels) at 50 fps enhancement; and

with two lower resolutions provided for scalability.

I defer to redspear on this one. It's obvious he knows a shitload more about this topic than anyone else here.

With that said, I'm done with this thread. I have better things to do.
