for hdmi cable what does 1080i,720p,576p, mean and which one is best to use cheers?

Answer 1

the best one is always the higher number :D

1080p is complete and full high definition..if your tv can get this high, use that :D

after that is 1080i..then 720 p..so on and so forth

happy high definition-ing! :D

Answer 2

It depends on the method of TV broadcasting or cable.

You sound English or Australian

576 is SD (actually 625 or PAL or SECAN). There are TWO HD standards in the US 1080i which is used by 90% of the broadcasters and is still interlaced for some silly reason and there is 720p used by only the American Broadcasting Company.

720p uses thicker scan lines (720 of them) from top to bottom in one pass (progressive or P)

1080i uses thinner lines but does it in two pases,540 odd lines then 540 even lines.

625 or 576 is your DVD or BROADCAST stardard.

DVD can be 576 progressive

Broadcast (over the AIR ABC Australia or BBC England) is interlaced 625 of which 313 odd and 312 even lines are composited to make an image (interlaced).

CABLE, DIRECT TV and SOME DVD is PROGRESSIVE

Here's the thing.

Engineers say interlaced uses less space (bandwidth) and works better because or AC refresh rates (50/60 Hz of AC power) and works better for thin scanning lines.

But it means in the case of a SOCCER player in motion that he is in a different place every other line (he moves) So he is 1/10th of an inch further across the screen for the ODD passes than he is for the EVEN ones.

In PROGRESSIVE scanning the bottom of the picture is 1/50th different from the top so it moves only a hair.

And ONLY if you are looking at the bottom

BUT the scan lines are thicker

NOW

Part of this DEPENDS on your TV

SOME TVs are 1080 i/p

They use 2 million triads of color dots (6 million dots) to make an image

a 720p/i designed set uses less. It uses 1.6 million triads or 4.5 million dots

So the resolution is lesser

BOTH sets can show 1080 i 1080 p 720 p 625 i 576 p 576 i 480 i and 480 p (American DVD)

They do it by CHEATING

And there is a loss in quality.

You can't avoid this

The 720 set turns the 1080 signal into a 720 scan

The 1080 signal turns the 720 into a 1080 scan

It is unavoidable.

1080 sets show 720 signals poorer than 720 sets, but only by about 10 or 15%

720 sets show 1080 signals poorer, but only by the same amount.

Usually the set AUTOMATICALLY adjust for 720 and 1080

Now for 525 (US) 625 (Europen) 480 (US) and 576 (EUropen) you MAY have to adjsut manually with the remote to spread the picture out.

A 576 set is an SD or HD PAL set

It will not show 1080 or 720 images

As far as I know at least

It will only show broadcast, standard DVD, VHS and CAble SD images.

You remember BETAMAX and VHS

We're back to the same thing

They should have gone 1080 p

That would have solved everything why they went 1080 i is beyond me.

Blu Ray and HD DVD is 1080 p

Broadcast is 1080 i

The bottom line is it don't matter much as long as it's HD and can do P as well as I and convert

You loose a little quality but until the dust settles we have to live with these silly multiple standars.

Around 2015 it will all boil down to ONE process

Until them we go with hybrids

Answer 3

The cable is not the issue. HDMI or component can carry all of those.

You need to read your TV manual and learn what it's native or internal resolution is. It will be some number like "720" or "1080".

Then, when you hook up a HD CATV box or high-def DVD player, choose the number that matches your TV.

Your TV will ACCEPT all the formats: 480, 720, 1080. But it may have to up-convert or down-convert. Since the source devices let you choose - pick the number that matches the internal resolution of your TV.

Answer 4

576p Resolution
