PAL/NTSC to RBG ouput

Recommended Posts

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!

May I ask you, Why do you need it?

 

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:

 

 

 

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!

For those interested, here my project so far.

 

Actuately, it's functioning!

 

Both cams are synced by a microcontroller.

Same microcontroller thereafter controlls the signals to be combined

as 1 vidosignal.

 

Set-up:

 

 

 

 

Combined signal ( this goes into transmitter)

 

 

 

 

 

 

At receiverside, there's a free app, what extract A and B into picture for left-eye and right-eye

on you phone. ( the phone goes into a VR goggle with 2 lenzes )

 

 

 

Logicanalyzer plot:

( see burst, ODD/even and line )
