How much is HD affected by PAL and NTSC?
Hello All
As we all know there are many different flavours of HD and I have always thought that the new HD formats were independent of PAL and NTSC standards. Any HD production going for broadcast or DVD-Video needed to be down sample/converted to that standards specifications.
But reading through some posts I

Hi Daniel,
I can not help you much because I don’t work in HD (in the 90% of the plannet the people still years away of the HD).
But I think the question you bring is very intersting. I see that the people that has grown-up in the digital era would like to get rid off everything that smells PAL or NTSC. Many people think that these systems are oldfashioned, but the truth is that they are really alive. In fact HD is just an improved PAL or NTsc. The developers didn’t yet find a better method than the one used by this to system, by managing Lumminance and Colour in the way they do. That the core of the old system and the comming sytems aswell.

PS: sorry but whenever I got the chance, I go in deffense of the old TV. I think that thes post to these forums would be reduced in a30% or so if the people would have a basic knoledge of what is call “The Video Signal”. But for many people with high scopes, seems not worth. When you learn for engineer you must know how a steem machine it works, even if is something already desapered. -
From Avid’s White Paper: Understanding HD
PAL and NTSC do not exist in HD. They do not exist in
modern SD digital television either -
If your client is in North America they will likely want 24p or 60i while in Europe they want 25p or 50i so though PAL and NTSC theoretically no longer exist in HD we still have the frame rate hangover and no worldwide standardization… Typical of the TV business. I guess we will survive this too.

Hello
Thanks, I think I understand, although the statement that PAL and NTSC doesn -
PAL and NTSC certainly do exist; as standard definition analog signals. They don’t exist in HD …

Confusionnnnnn..
What ever you can watch in a normal TV set, is PAL, NTSC or SECAM in any of their variations. The signal you get from your DVD player, that you plug in your TV, is PAL or NTSC. The Video Out (componet or compoite)you get from your camera are PAL or NTSC. PAL and NTSC do not exist? Wat a joke.
There are not any SECAM preset in any programa, because SECAM is a format for broadcasting only. You can not post-produce in SECAM, because the colur is “sequential” (the color component are modulated one after the other. In the countryes that SECAM is used (France, Russia..), all the production is done in PAL. SECAM exist only when the progarmm is aired.
As I said before, I think many people should put theirs feets in the ground and learnt about VIDEO. We still have a lot of years of PAL and NTSC in front of us.

Hi again,
I’m not an engineer, but from 1985 y worked with all the analog formats in the market (except 2″) and few digital too.
NTSC is basically a B&W system improved. PAL is an improved NTSC, and HD is just the evolution of the older systems.
Some people relates HD to digital. HD exist since more than 20 years ago. in 1985 I’ve been in a seminar about HD in the IBC in London, and them they were already few systems ready to work, but not a market yet.
In the evolution of the standards in TV has been equally important the technical consideration than the economics. The rise of the Beta-cam wasn’t due to give a better quality than the older standards (Beta-cam doesn’t reach the quality of the !’B or 1″C), but due to the fact that the equipment were cheaper, lighter and the footage easier to store. Also from the technical point of view brought two advantages, first to get rid of the “Color Framing issue” (working in composite analog video you can’t always set the edit points where you wanted). And the second is to manage the color information separated from the luminance (so you had not need to filter the signal to extract the components and manipulate them).
HD is a bigger building, but made with the same bricks and cement than the SD.The revolution hasn’t be in the standards. The revolution has been in the tool. DIGITAL. The think that has made possible that for few thousands of dollars you can make a film that not long ago would have cost you few hundred of thousands.
Went I started to learnt video, although I was living in Europe, I had to learn the NTSC system before to studying the PAL, because if you don’t understand the first, you can not understand the second. With the HD it’s happens the same.
So my in my humble advise, for the people that doesn’t have a basic knowledge of what is the “video signal”, to spend few hours to try to understand them would be highly useful. How can we talk al day long about codification and de-codification, if we don’t really understand what we are codifying . And don’t get scare, I swear that is easier to understand the whole of the NTSC and PAL systems, that a single page about digital compression.
