Interesting reading, so much for us early adopters with component only
inputs. I'm surprised as I thought they would adopt something that would
allow us to receive a high def. signal without the necessity of HDMI or DVI
inputs. While it says the studios can release movies without the "Image
Constraint" I'm betting they all go along with it.

Hugh,

Now the ball is on each Studio. No more pointing fingers to each other giving excuses and the
typical "I do not know (in Korean and Japanese)", for 5 years I heard at CES.

One thing it is not said, not that I am eager to get anything sub-HD, is how the 540 frame would be
obtained:

A) throwing away every other field, take the chosen 540-line field and make it a 540-line frame with
the 1920 horizontal reduced to 960, and then doubling up those 30 fps frames to 60 fps for a
progressive presentation of 540x960 60fps, or

B) blending the two 540-line fields into 30 fps of 1080x1920p using motion adaptation, scale those
1080x1920 30 frames down to 30fps frames of 540x960, and then doubling up to 60fps from there.

Big difference. (A) will butcher 24fps film sources big time.

Although someone I could not trust was saying that Blu-ray will actually store 24fps film content
exactly like that, not like they do today with DVD as interlaced with flags, for playback
recognition and 3:2 pulldown. If they would that the High Def DVD would be the first DVD format to
store progressive film and interlaced video using different physical methods on the same disc.

This 540 field butchering is a similar problem we have with the 1080i to 1080p bobbing technique
used in most 1st generation 1080p sets, but this is worst because they also cut in half the
horizontal resolution for 1920 to 960.

But guess what, even those 1080p sets with HDMI would suffer some aberration because they have to
receive the i1080i version, and build one frame from one individual 540-line field.

This is very disturbing, they are screwing up about 10 million people that WILL see the difference,
early-adopters were early because they want a quality difference they can see.

Thanks for the link.

Now, if someone can help me getting the original ruling (I prefer the specs) from AACS, and also the
echo from DVD Forum, and the BD Association, not another reporter's interpretation, you will be
helping me and everyone else getting the CES report earlier.

Best Regards,

Rodolfo La Maestra

The 10 million people with component only inputs are becoming a smaller and
smaller minority. In 2005 alone they sold 15 million digital sets. They will
sell even more in 2006.
I bought my first HD set in 2001 knowing full well that I could have down
rez problems in the future. But I never did since I replaced my set after 4
years. The person that I sold it to will not be connecting any type of next
gen DVD player to it. And I'm sure they are not the only ones with a
component only set that won't be connecting one.
I bought my current set knowing that it would not accept a 1080P signal
over HDMI knowing what the consequences would be. But I am fully enjoying
the set right now, like I did my component only set for 4 years.

Rodolfo,

Thanks for the comments on this issue. I think we can assume that they will
use the least expensive method of obtaining the 540 frame rate. I still
think they are crazy but then it is their business.

Regards,
Hugh
