Frage von sinistersnipe:
Hello
I think about my DIY Ambilight to build. I will accomplish by I have a microprocessor so that the programming rgb data of a video source ausließt, per-forming the average color will take place, and then with help of 3 Luxeon LEDs is reproduced.
You need to have but I know exactly how an RGB signal is transmitted (do not know whether this is relevant, but I plan it out of a SCART connector off zuapfen).
What is it with the luma signal on the on green / blue is laid?
how accurate the color at all over?
it might be easier to just S-Video/Composite signal to use?
with a frequency for which the images are transferred at all?
what because of v / h sync to consider?

That should have been but a good overview. Here is what Color s.den corresponding pins is transmitted. When it is finished, post some of our instructions ;-)

Antwort von prem:
yes thank you, this article Ahbe synonymous but I have found. I am interested halt EXACTLY how the data are modulated
Antwort von magic-lighting:
I think it would make is simply that not with a ¼P not realize, because most controllers are not in the position would be a Siganl with several MHz digitizer or entsehenden amounts of data to process. Moreover müsten the Horizotal or vertical signal yet from the Scart signal, which is just out of the 3 RGB signals with synchronization aufmodulierten signal to be filtered.
With a VGA signal could be something simple eiegntlich synonymous, because here all 5 signals are available separately. Simply each R, G and B, low pass filter and the voltage level at a driver of the Luxeon in brightness controls give. Is not frame accurate, but should actually work - even without ¼P.
Antwort von sinistersnipe n/ angemeld:
I've considered the really synonymous with an operation amplifier should go on the first try I s.RGB from SCART, if not then stop VGA since then but I would need an adapter.
Are these vga -> s-video cable as what they are Hauf at ebay? wants no money for a real converter output.
grateful if
