1st of all, you might want to stop mentioning about pirate dvd, or anything related to pirate for that matter. this forum does not condone piracy. the only pirate you can mention is Jack Sparrow, Se7en is a big fan of the man.

dvd dics, no matter which one, only max to 480p. you can upscale it by player that support upscaling, but the quality can't compete with true 720p / 1080p video.

you have to understand what HDMI is. it is just a way to connect to your tv. the only different of HDMI and component from composite (Yellow RCA) is this 2 connection can carry signal until 1080p while composite can only carry 480i.

HDTV FAQ

The purpose of an upscale DVD player is to upconvert ALL types of DVDs from the standard 480P to 720P/1080i and upwards using HDMI. This is for those who have not yet upgrade to Blu-ray but want something in-between for the time being. HDMI is not exclusive to just Blu-ray. It's just a digital component standard for transmission of HD quality signals.

The quality of the upconverted picture depends on the Brand of the player and the quality of the processing Chip used in the player. Of course the quality won't be as good as the real thing from a Blu-ray player.

Sometimes a really bad upscale player can be worse that the upscale done by your TV using a standard DVD player through Component. But this rare.

(Note:- FYI, Upscale players used to be able to upconvert to 720P/1080i through Component video also in the early days, but they are not allowed to do that anymore nowadays because of some regulations/protection and other issues. So the current upscale players only upconvert using HDMI now)

Added on November 2, 2008, 11:13 pmThanks for the great info.
This helps me a lot...!!

I want to try how to get to 720p...
Any big difference in between 1080p to 720p?

Besides the comfort and enjoyment, I believe watching on a better picture quality from TV is better for our eyes.

Thanks again!!!

If your TV is only 720P/1080i and not not full HD (1080P), your TV wont be able to accept the 1080P signal from your upscale DVD player. You will probably get a blank screen. You will have to make do with a 720P/1080i signal which is sufficient for upconverting normal DVDs. You can choose the upconvert resolution from the Upscale player options.

Take note, 1080i is not full HD, only 1080P is full HD. 1080i is more like 720P in terms of quality.

To take full advantage of 1080P you need a Full HD LCD TV and a Blu-ray player playing a Blu-ray movie.

Huah...

1080i and 1080p...??
What is the difference in between :i" and "p"??

I guess 1080P is true full HD?
Meanwhile for 1080i is something like from a upscaling? right?

1080p is a progressive signal. 1080i is an only interlaced signal.

Technically speaking 1080i is worse in quality than 720P. But some people find it looks slightly better than 720P. It depends on the combination of your LCD TV and upscale DVD player. Sometimes it's also in your mind.

Fyi 1080i mode can be displayed and is a common feature on 720P LCD TVs because it is not full HD.

Of course both 720P and 1080i will be nothing close to 1080P.

1080i vs 1080p is the same as 480i vs 480p.

480i (the normal display from our tv channel)
480p (when you use dvd player with component cable and enable Progressive Scan)


if you count by lines, 1080i is much better than 720p. if you count by flickering (less) then 720p is better.
btw all the "Full HD" is useless if the tv only 32" and you're sitting like few meters away.

btw, if HD only considered as FULL when is 1080p, then what if they come out with 2160p? TRUE HD?? REAL HD??

Thank you for your extra clear information.

I think I will be happy if my LCD TV can get 720p.

Added on November 3, 2008, 3:48 pmSeriously, I think all of you can combine your professional knowledge and publish a book.

I do not think sales persons from any electrical shops (like HSX, Senx HenX, XenQ, CourX MamotX, OnkinX) have this kind of knowledge.

Thank you very much for the tuition. Really appreciate it.

beside the link i given earlier, if you got time you might wanna read this thread, if i'm not mistaken the first 20+ pages has a lot useful information on HDTV.
HDTV v1

We were talking in terms of upscaled 1080i input to a 720P TV.

When a 1080i interlaced signal is fed to a 720P LCD TV (which is progressive in nature) the signal is de-interlaced and scaled back to 720P (or rather 768 progressive lines to be exact) by the TV itself. Don't think that you really get 1080 lines of interlaced video.

You can only input 1080i to a 720P LCD but ultimately they will be displayed in 720P. (The info shown on the LCD menu might indicate the signal as 1080i, but that's only the input signal).

Because the original DVD 480P (true information) is upscaled to 1080i (true + upscaled info) and then re-scaled back to 720P by the TV , you have a double scaling, which can potentially lead to a worse picture than just upscaling to 720P and passing it to the LCD without much further re-scaling by the TV.

But for most people 720P and 1080i looks almost the same because ultimately they are both displayed in 720P by the LCD.

oh, ok... because in your previous post you never mention about the original source is from dvd video upscaled to 1080i.

but how come on your last paragraph you say 720p and 1080i looks almost the same?? shouldn't 1080i looks worse because it has been upscaled then downscaled back, as what you says in the previous paragraph?

I said for most people it looks almost the same .

Technically although it might be worse, the difference is not too noticeable because whether it's 720P or 1080i , the final output on the TV will still be in 768P (doesn't apply to full HD TV of course). At a distance the difference might not be obvious.

Anyway other factors also come into play, which can affect the quality, like the combination of the upscale DVD player and the LCD TV itself. Different pairing and enhancement features can even cause a double scaled 1080i picture to look even better than a single scaled 720P picture at times from a distance. It's a matter of chance and also the eye of the beholder

That's why sometimes some people find that 1080i looks better than 720P and vise versa. But for most people who are not too critical , they won't notice the difference.

Added on November 5, 2008, 9:59 amI think I should stop posting anymore of this boring upscale stuff because I just realised this topic was originally about component cables.

My apologies

Take it easy. This is not boring at all.
Ngto does not need to apologize.

But this a new and interesting knowledge to learn
since we have switched into popular digital signal and LCD TV.

For me and for other people who are new in this area, we need time to
digest and learn step by step slowly. And for me, I have learned a lot here.

And for the rest of you who understand better, you guys can exchange information and learn from each other.

Thank you for all of your contributions and valuable information here. I hope we can carry on... Thank you

Update to Blu-ray soon

at first i gave up my hope on DVD when i first watch bluray movie..
howwever, i was pleasantly surprised.. when i pop in DVD9 movie into ps3..
and thru HDMI it upscale it to 720p..
the outcome is really really huge step of upgrade as compared to dvd without upscale..

and juz like andrews said.. its combination n pairing of devices that will make a difference..
remember only HDMI can allow upscaling, not any other connection will allow it no matter which 1080p dvd player u use..

I know about PS2 mouse and PS2 keyboard.

What is PS3?
