I've scrolled past this meme countless times, but somehow I didn't think of this before now: What does an composite video signal sound like?Anyone have the hardware to test it out and record the sound for me?

I've opened serial terminals to serial mice, and I've abused /dev/dsp with random binaries I've fancied at the moment, but it never dawned on me to plug the red or white RCA jack into the yellow port in the mame of science, and now I only have audio RCA..

EDIT: Composite video, not s-video

In the worse quality TV, putting the composite video into an audio line would make the speakers do a short distorted buzz, then cutoff. The higher quality TVs won't even flinch. Their internal processing was fast enough to detect the wrong thing was connected, that the signal modulation never even made it to the amplifier. But to our ears it was probably just a bunch of electronic farts.

I do t m ow what it sounds da like but i know what it looks like. It’s basically modulating for every line of your TV high is bright and low is black with a marker for each line.

If I remember correctly it does not make ant sound. Another commenter says its due to advanced audio processing.

I worked at Best Buy and you'll be amazed at how many people couldn't figure that out. I was also a genius for showing my in-laws how to select input to display their dvd player.

[–] ohlaph@lemmy.world 2 points 9 months ago

Wait, you can select it?

Unless you only had component connections then you had to plug the Yellow into the Green port.

Yes, seriously: https://en-americas-support.nintendo.com/app/answers/detail/a_id/3008/~/unable-to-locate-a-yellow-video-input-on-the-tv

Also, don't pick the wrong red.

Back when radio shack was there to help you figure out how to connect the thing to the other thing. The usual problem was you had the one multi-colored thing, and the thing it was supposed to connect to did not have matching colors or matching anything at all.

If you get the hang of this, quantum chromodynamics are going to be like a walk in the park.

The only one that was hard was RGB. Any only because it had 2 reds and some cables didn't distinguish which red was which.

[–] AgentGrimstone@lemmy.world 4 points 9 months ago

You have to do it without looking tho. That said, I actually found them easier than hdmi. With hdmi, even if I have it the right way I sometimes think it's the wrong way because it isn't aligned properly.

[–] A_Random_Idiot@lemmy.world 4 points 9 months ago

wasnt about getting the colors right (which was a challenged trying to get cables connected in tight confines..) it was about how fucking tight those sockets were, and the closer the plugs were, the tighter they were by some bizarre happenstance, so ones super tight up against eachother like that would be near impossible to shove in, especially in cramped confines that you typically had to work in.

I had two pieces of equipment to connect and when I matched the colors it wouldn't work. I had to swap two of the colors. I think they misprinted the colors on the unit.

Fr real. Also, am I old now? I'm not even eligible for jail yet.
