It is a screen display ...

Price inquiry:
How much is 768 divided by 16 times 9?

No matter what he refers: 720 * 405 and 768 * 405 are WRONG IN ANY CASE!
Soso, photographer is the best! So neither a rational humanist nor a decent scientific education! Yes, they are drawn to the artists - with the numbers they have not so .....

Antwort von Peter:
What is "Screen Display"? What a screen? Where does the video come from? Where will it appear and what will it go?
For PAL video (analog video) 768 * 432 would be correct.
When letterboxed 16:9 DV PAL 720 * 432 would be correct (768 * 432 is the 4:3 Television).
For anamorphic 16:9 DV PAL 720 * 576 would be correct (is 1024 * 576 on the 16:9 Television).
With HD (T) V, would be 1920 * 1080 and / or 1280 * 720 right.
With flat screens in the 16:9 format, the device Resolutionvor.
So, without further information, a question not clearly answered.

Antwort von Markus K.:
Thanks for your answer.
But what do you now what I should take a resolution for the 16:9 format?
daxe-AT-gmx.de
Antwort von Marco:
I believe that PAL DV 720x576 Always a Resolutionvon, whether 4:3 or 16:9. The only change is the pixel aspect ratios. Also had 16:9-Letterbox PAL DV at the same resolution, but with black bars above and below, which in this case actually includes the image content. I'll not next search, is just what I have in mind, and it is, as my cameras and NLE editing systems (successfully) treated. The starting point is naturally an anamorphic picture. Maybe in a non-anamorphotic Picture as a basis different.

Your details were correct 768x432.
It was in this role again ....
Since the teacher has said something wrong.
Thank you for your efforts.

Antwort von Peter:
Addendum:
Marco has quite naturally when he says that PAL DV always Resolutionvon has 720 * 576! Taking into account the fact that our result somehow transported to the station must, we have two options on the DV tape to:
1. In the letterbox format:
This must be a 16:9 picture on any of 768 * 432 gbracht be at the top and bottom, each of 72 black line and then added to 720 * 576 stretched (not circumcised) are.
2. In anaorphen Format:
This must be a 16:9 picture on any of 1024 * 576, and? 720 * 576 to be squashed.
With the last method would be for the DV format, the greatest possible information to the transmitter, which is required procedure ers would be a dissolution, and thus a loss of information mean.

To do not quite want to confuse I do not even delve into next and certain differences between the conversion from analogue TV to PAL DV just "Schlabbes".
The Resolutionvon 768 * 576 For the "normal" 4:3 TV is already correct. Although our TV at the time being an analog medium, which really only in pictures, fields, lines and frequencies based but would be the visible portion of the television image in pixels qudaratische split would be at 768 * 576 pixels.
Let's assume that we have hinschicken was synonymous again comes out, it would require 730 lines correctly. This results in accordance with accounting None 16:9 but it sends the television PALplus (16:9):

From this response to my request to the Bayerischer Rundfunk television show that actually broadcasts 430 lines, just two less than I thought. Strictly speaking, this is synonymous not 16:9. Even worse is it when one knows that for playback on 16:9 TVs, the vertical lines Helper regeneration of all lines to a full picture with 576 lines allow - which is then stretched horizontally, however, is for the full 16:9 television to fill .

Antwort von nitron:
Screen display (as he calls it and so we can get the evidence) is just a still image for television. Nothing more and nothing less.
Our task will be tomorrow, the following:
We have with Photoshop just to create this statue, most likely in
16:9 aspect ratio, so we are almost finished after a broadcaster to send
, which is then on the screen to flicker.
The other question is, why we are actually trying to teach,
if it is here already understand such problems. But I have a feeling
our teachers because we have a bit verschaukelt what the acceptable values.
Would not the first time that he had something that he should teach us, myself
gepeilt has no meter.
As I said, dieunsererseits values seem to be down a little
to oppose. What makes for complete confusion, as you probably already noticed
hast;)
We have to create a screen display ever been through.
And since this looks like from below:
In Photoshop, we have the usual TV, that is 4:3, with a Resolutionvon 768x576
worked. If you tell me now, that is wrong, it would not surprise me.
Our problem comes again to make very clear is that our task
most likely suggests a complex screen display in 16:9 format, suitable for TV to make.
Again thanks for the patience, incidentally;)
Antwort von nitron:
Hmm, I again refer to me as yourself.
What a cramp.
Just for once, just a minute.
Antwort von nitron:
Hallöchen synonymous,
'm a colleague of Mark's class and would like times here
a little quick to meddle.
Our record was not of a German made
on the contrary. The photographer is good and there no cent
the spelling.
So, as follows.
Standard Resolutionist yes for 768x576 square pixels on a PC.
But TV standard (because of the anamorphic pixels) is 720x576.
As far as right?
16:9 For I have in my ring block are:
720x405 (anamorph)
768x405 (square)
Can it be that our teacher refers to HDTV?
Ulead Because MS is synonymous for 720x576 at 16:9.

Addendum:
.... by 8 or 16 divisible .....

-AT-Markus:
Maybe was a Deutschleherer? The would be with a three-course hopelessly overwhelmed.
16:9 says, as the term shows that Width and Height to 16 to 9 Code. When would be the 768 Width 432 Height and Height at 405 would be the 720 Width.
Aaaaaber - just the latter ratio would be your teacher on the boardwalk because PAL DV (he probably wants it more), usually with 720 * 576 dissolved in 16:9 still has not 720 * 405 but 720 * 432 pixels! This is that when playing back DV in width by a factor of 1.0667 is stretched, in the Height but remains unchanged. The NICHTQUADARTISCHEN PIXEL DV format are so stretched when playing a PAL 4:3 display to realize. If the DV - WOULD square pixels (they are not) then it would be purely arithmetically on the value of 405th But since it was NOT square pixels are synonymous must be the right answer as 432 noisy. A Resolutionvon 720 * 405 is definitely wrong, come into practice and can not with many codecs do not be generated because they are a 8 or divisible by Resolutionerwarten.
Only such a complicated mathematical and technical Überlegeung it is still today a maximum of one or Mathmatik physics teacher expected.
