Frage von Matthias Kletzsch:
Hello,
a problem which we have long been employed but still no solution in sight. Above all, we would like to understand the problem.
For large events and conferences we have a throw projector, the picture of the speaker and PowerPoint files s.eine canvas.
At a Panasonic WJ-AVE55 video mixer and a laptop connected Cam. If we now the video (no preference SVHS or RCA) of the notebook directly s.das Puklt connect, we get very poor results unacceptable to the black and white distorted image. At the moment, so we solve that we have the signal from the notebook via a DVD recorder and then redirect s.das mixer, works flawlessly and gives a clean picture.
So question:
1. what is this?
2. what does the DVD recorder to the signal so it can improve?
3. Can synonymous with another device to be made and if Yes what?
cordial greetings and with great hope for an answer

Is the laptop the correct TV standard is (probably PAL B / G)? According to data sheet and manual and website Yes, it's PAL. It is a Fujitsu-Siemens Amilo. Do not know whether any bad blocks used.

Preliminary. A quasi-XGA signal Downconverted but looks horribly out anyway.
If we Vweanstaltungen Real movie mix with powerpoint we use technology to both the video image as synonymous, the XGA projector output signal s.den.
Since such rapid mixer 10000 Euro cost, we manage to Lowbudget solutions with a signal source switch.
Then it is no longer possible to mix but at least you have ne portable quality.
Wennn her but wanted to make wirklic so then I would just try the following. Close the notebook s.einen professional Beamer at. Many could be a status message to spend what it anlieft. NTSC PAL PAL UMD which the refresh rate.
I would only at times synonymous wrong video standard type.
It could, of course, that the video signal from the notebook is so bad that the mixer can not cope.
The Dvdpayer then in your case, simply a clean signal with Sychpulsen clean.
In such cases do sometimes when you do not want to use DVD Player to small boxes previously used were analog marko vision Copyschutz to circumvent. The quasi-synonymous prepare the SYC in the video signal and to thereby provide for an equitable standard video
Antwort von PeterM:
The notebook can output Pal still says nothing about the settings are correct. These are indeed in the display driver set and are variable. I knew as my Notebool to übereden with 60 Hz PAL signals, so a signal with the mixer no longer karkommt
Antwort von Markus:
This following information:
What says "PAL" alone already?
Antwort von RK:
as I know, the mixer is not with the signal lines zb. 625 lines cope. This is the error, because the cam and the recorder going, the only explanation. When the signal is less, such as 625 lines, the picture plays with and is not distorted, it then needs to be synonymous sides, run away. "

Antwort von thos-berlin:
I mix a computer image from the CVBS output of a graphics card without any problems via video mixer into a video image. The picture is not much worse than the real video image (of course, worse than if one would work via RGB).
The only drawback is the black stripe around the PC video screen, so it only flashes when writing Luminanzkey (Black cut) should use.
When the signal on the DVD recorder vearbeitbar who is perhaps the Signalquallität the graphics card is not good. Or should the DVD recorder may be a standard converter and / or a TBC have integrated?
