I have read that HDMI can carry 1080p but what about these other two, DVI and component?

Theres a 1080p??? I thought 1080i was it??? anything higher than that would be 720p or 1440i. A 1080p would mean 2160i...Been wrong before though... :smokin:

1080p is not 2160i it just means that unlike 1080i which scans the odd lines first then scans the evens lines 2nd 1080p paints the whole image at once which is why its progressive and not interlaced.....

1080p/60fps is the best possible out of the 18 ATSC selected formats, which I believe start at 480i and go all the way up to 1080p. Currently however there are very few tvs that can do 1080p and they're expensive! As far as I know there is no 1080p content to watch anyway...for now.
Sorry I was wrong, 1080p/30fps is the highest ATSC format.

However I believe 1080p/60fps will be the ultimate in the near future.

Is it going to be just an upconversion of SD material or will they upconvert HD 1080i and 720p to this as well? I have heard that the Samsung DLPs will be going to this later this year. Is there any truth to that, and is anyone else talking about doing it? I am waiting on upgrading from my tiny 27" HDTV to see what happens with 1080p, and i am also hoping for more digital inputs on the TV to make it ready for connection of future HD sources.
Thanks for any light anyone can shed on this.

There's enough problems with trying to get (more) programming at 720p or 1080i. IMO... right now, I wouldn't be limiting my future purchasing descisions on 1080p.
Especially with no 1080p source material (today). Unless you have the money to spend to position yourself for when it is available... and have the cash to burn.
I can't address how much 1080i to 1080p really improves the picture quality. I can't imagine that it would justify the $$ at this time. I could be wrong...

If going 1080i to 1080p is the same as 480i to 480p was...I'm sold.
I agree Ratman the content will have to come a long way first.

I think your chances of every seeing broadcast (i.e OTA, cable, or SAT) 1080p are virtually 0. The studios have finally invested hundreds of millions on 1080i or 720p gear they are unlikely to change soon.
However I think 1080p could still be a good buy:
1) If the original content (film) was progressive, then 1080p could provide a more "film like" picture. It is a simple conversion from 1080i to 1080p. It won't be a better picture since you have the same amount of information, but it would produce a cleaner smoother image. Just as a DVD played at 480p has same info as DVD played at 480i, however 480p looks smoother or cleaner to human eye.
2) DVD-HD standard is still up in air. It is possible that discs could be encoded at 1080p. The player's then could downgrade to resolution needed (1080p, 1080i, 720p, 540p, 480p, 480i). DVDs per intended to be used on analog sets so they were encoded @ 480i. It actually takes some work to worsen the film by interlacing when creating a DVD. Since HD will be commonplace by then time DVD-HD comes out it would make sense for studios to agree to a progressive format for quality and encoding reasons.
The big point will be $$$$. If a 1080p screen is 50% more than a 1080i or 720p screen consumers will not buy it. Let's face it average US consumer doesn't read HDTVoice.Com.
One potential good trend is Intel investing in Lcos. Lcos is currently an expensive all digital system. It can output 1920x1080p natively. However it is expensive to produce. Intel is working on a 1 chip design that could be used in all HDTV sets. This could allow for mass production and lower prices. Intel is predicting sub $1000 large screen HDTV based on 1080p lcos by mid 2006.

Since we are talking about 1080p I thought I would throw this in:

Aren't the new digitally mastered movies shot in 1080p? Star Wars ATOC?

Nice article Lee. Most of that went over my head but it does look like 1080p/24 will be the format for digital masters. As more theaters switch to digital equipment more producers will shoot in digital making even the film to digital process redundant. I think digital film will catch on not because digital is better or higher quality, digital is simply easier to work with in terms of editing, distribution, encrypting, acrhiving etc.
In my earlier days I worked as technical support rep in Canon EOS department (digital pro series cameras, and lenses) The 1DS with it's 11megapixel full sized CCD and compatibility with canon ES lenses switched a lot of pros to digital. Most of the ones I talked to didn't think that digital made their work better, it simply made it easier. No need for dark rooms, chemicals, aging negatives, and mailing proofs around the world. With digital you can shoot more, quickly select the images worthy of proofing and digitally transmit to editors all in one day.

Someday the digital theaters will just download their movies directly to the projector. There will be some kind of protection I'm sure.
Fully automated theaters, just put your $10 bill in the machine and get a box of popcorn :)
I picked up a Digital Rebel and use all my old Elan IIe lenses. Very nice camera. 1gb 40x card, I can take pictures all day, well actually approx 275 pictures at 6.3mp :)

I read an article on digital theaters (forgot source).
Basicly a digital theater opens up new revenue models. One theater has an agreement with DirecTV to show pay per view events (boxing, wrestling etc) in HD.
The owner of theater said the margins on those specalty events are much higher than with movies because 1) content is cheaper and 2) people are willing to pay slightly more for something different.
I know personally I would love to see sporting events in HD on a massive screen (if they served beer)
