Any device to split video into seperate X, Y, and z axis?

[Videotechie]

If anyone knows of any gear that can split composite video into separate X Y Z axis please let me know.
Thanks

Can you explain a little more what you mean? It's clear that you want to input analog composite video, but what output are you looking for? A 3-D Fourier transform? Signal filtered into separate luminance and chrominance subcarrier signals?

Horizontal, vertical and temporal axes have been used in theoretical three-dimensional Fourier transform of scanned video systems. This is usually done in a computer program and leads to the design of hardware like comb filters for analog video.

I'm curious what you're attempting. Waay back in the day during some slack time in the shop, I was goofing around with the scope. Put horz and vert (X and Y) sawtooths from a working TV on the scope to form a raster, and luma in thru the Z input on the back of the scope, which displayed the live video from the TV. The Boss came in and looked at it, and wasn't particularly amused.

You mean to vectorize the image? https://oscilloclock.com/archives/tag/vga

Even with one of the creators of vector clocks (in this mode it works with vector), I think he used rasterized mode for graphics

Yeah, but the scope was displaying actual off the air programming. And the pic didn't fill the whole screen, just a square about 2X2 inches.

Boss should've given you a raise for creativity

Turned out he didn't realize the scope had Z input on the back.

I'm looking for devices ready to plug and play to make an Oscilloscope display for video. Everyone's input is appreciated some great pics of what some have done.

There is no such device, you have to make one, I have thought of doing such a thing before.

how to do it is tricky but it has been done before.

how to do it is here..

W2AEW did a YouTube video about a simple circuit you can build (using an LM1811 sync separator chip) to view composite video on an oscilloscope:

Jesus...and I have enough problems getting a 4:3 image on a 10BP4 CRT. Maybe in my next life...

Setting it up is a fun learning experience, but the novelty of watching TV on a scope wears off fairly quickly.

[Yamamaya42]

So, hulkifyng your oscilloscope to watch TV get boring?

[old_coot88]

Once the proof of concept is actualized, the novelty wears off mighty quick, 'specially if done on shop time.
