Hi,

recently started using the LM1881 ic's.
This ic extracts sync-signals from composite video signal.
Things work fine!

Now, I'm looking for an ic that can extract R-, G-, B-signals from composite video ( video over 1 wire ).

Googled ( like 'pal to rgb encoder' etc ) but I only find RGB to PAL ic's etc...

Anyone who can give me a hint for an ic ( or schematic ) ?
Like to have the color signals seperated.

Kind regards!

Could this be an idea?

Again: I got the sync -signals allready!

One cvbs input will do too,as long there's RGB-out!

Hi,
recently started working on a 3d/stereo FPV setup.

3d FPV looks very expensive, so I briefly made some ideas.

During this I found following setup, and deicede to try that first:
This specific setup, uses 2 cam's ( PAL/NTSC ), a (small) microcontroleller and an ic (4066) for switching
analog ( PAL/NTSV) and a FPV transmitter. it actualtely switches (in sync) between 2 cams.
Here's the link:https://www.instructables.com/id/Lowcost-3d-Fpv-Camera-for-Android/
Both eyes see alternately the picture from right and left camera.
(Both eyes see the same picture at the same time!)

So far...


The goal is like this:
Attachment:
rgb sync.png



With a step forward, one could devide the colours, to get more 3d effect etc etc...

I will not go in details here.

The cam's wil be in sync (controlled by microcontroller ), this works fine.
The 4066 work fine, too.



( cvbs1 and cvbs2 could also be swithed, so only 1 "?" is needed. )

Mmm...for he time being, I'll keep my design as it was.

This means: no colour seperation..

Just playing with the frames of both cam's.

Allready 've seen some tests, looks promising!

Kind regards!
