Inaccurate meme - the white and red RCAs in composite typically don’t actually carry the left and right channels - usually, the white one is L+R, meaning both the left and right channels combined into one, and the red one is L-R, the difference between the right and left channels.
This is done so that a mono television, which will only have a yellow and white port, will still be able to hear both audio channels, as opposed to having to completely miss out on one of them
Wow, Til I guess. Never ever thought that this is what actually it is for.
The video cable does a similar trick with how it supports color. This is why S-Video was superior to composite video until component came along. S-Video split the intensity and color into two signals and then component split the color further into a blue difference and a red difference. If you only wanted black and white, you didn’t need to use the color signals and the image would degrade to a monochrome representation.
The composite video, with only one video signal wire, was similar to what was received over the antenna, with the broadcast signal separated from the carrier signal and the audio sub bands removed. It was the video signal with the color signal still combined. The progression from Antenna -> Composite -> S-Video -> Component -> DVI-I -> DVI-D -> HDMI -> Display Port has been an interesting one. The changes in the digital realm have been less about the image quality, the digital signal can either be read or not, and more about the bandwidth and how much data can be sent, aka resolution and framerate. Those first four transitions in particular had significant impact on the image quality.
Do you have a source for this? AFAICT this is untrue. Mono audio using just the white connector exists, but this depends on configuration and does not make the red connector a difference signal.
I swear that I’ve seen it mentioned somewhere, but you are entirely right that I can’t find a source. Maybe it was some weird device I used a long time ago? Regardless, sorry for not doing my research before posting
The signal in fm radio works like you described. Poor fm, declassified to just some weird device :(
This must be BS or a regional thing. All the RCA ports I’ve seen in North America are labeled L and R, not L+R and L-R.
I use those on my speakers and I can flip left/right stereo if I flip the cables. I think that confirms that they don’t have both in one I think.
It’s possible that it might only be a thing in PAL regions - I’d try, but I don’t have anything that uses composite to try now.
I can confirm that everything that uses component and L/R that I have used in my life (born in 2001 in the Netherlands, so PAL) has separate L and R channels. I have confirmed this with my multimeter before.
Oh, they did the same with stereo radio.
I appreciate you starting this comment with ‘Inaccurate meme’. I think it should become a thing. Really helps me know to buckle in for something good

I present to you: the Scart.
Our gaming consoles came with it.
We were clueless the first time we hooked up our N64 at gran-gran, since the old TV did not have a Scart connector, but we figured out that the Scart’s colored cables go in there.
Scart was amazing. RGB, composite, component, audio. All in one cable. Granted that cable and connector were enormous, but one cable nonetheless.
SCART was terrible.
Theoretically it had all that in one cable, in practice it never did. You’d usually have 3-4 SCART ports on a TV, but not all ports accepted our output the same signals. There was no way to tell from the outside what the output or input from a SCART port so you either had to try different port combinations or look it up in the manual (if you had one). Most TV’s had one port that accepted s-video, on that accepted RGB and they usually accepted composite on all ports.
Worse, not all cables had all 21 connections. If you were lucky you could tell because not all pins on the connector would be there (but this wasn’t necessary the case).
Usually there was also one port on a TV that output the video from the tuner. This was used for analog pay TV decoders. You would hook it up to that SCART port and it would get the scrambled video from the TV and return the descrambled video over the same port.
Also, due to the size and design of the connector it was almost impossible to insert it blindly. Inserting one into the back of one of those enormous CRT television was always a challenge.
Oh yeah the shielding was a nightmare to align with the socket correctly
VGA was so much better.
The composite video output commonly seen on 1980s microcomputers couldn’t display high-resolution text without severe distortion making the text unreadable. This could be seen on the IBM PCjr, for example, where the digital RGB display it came with could display 80×25 text mode just fine, but if you connected a composite video display (i.e. a TV) instead, 80×25 text was a blurry, illegible mess. The digital video output was severely limited in color depth, however; it could display only a fixed palette of 16 colors, whereas the distortion in the composite video could be used to create many more colors, albeit at very low resolution.
Then along came the VGA video signal format. This was a bit of a peculiarity: analog RGB video. Unlike digital RGB of the time, it was not limited in color depth, and could represent an image with 24-bit color, no problem. Unlike composite video, it had separate signal lines for each primary color, so any color within the gamut was equally representable, and it had enough bandwidth on each of those lines to cleanly transmit a 640×480 image at 60Hz with pretty much perfect fidelity.
However, someone at IBM was apparently a bit of a perfectionist, as a VGA cable is capable of carrying an image of up to 2048×1536 resolution at 85Hz, or at lower resolutions, refresh rates of 100Hz or more, all with 24-bit color depth—far beyond what the original VGA graphics chips and associated IBM 85xx-series displays could handle.
Also, the VGA cable system bundled every signal line into a single cable and connector, so no more figuring out which cable plugs in where, and it being so future-proof meant that, for pretty much the entire '90s, you could buy any old computer display and plug it into any old computer and it would just work.
Pretty impressive for an analog video signal/cable/connector designed in 1987.
I didn’t stop using VGA until I had a monitor new enough to not support it. Also, DVI was great because of the VGA support.
I still use it

Composite cables.
Red is Right Audio
White is Left Audio
Yellow is Video.
Vincent van Gogh cut off his left ear but has his sight.
Mozart lost his ability to hear but has his sight.
Ray Charles is blind but unable to see.
Ray Charles is blind but unable to see.
ah yes the floor here is made out of floor
Gotta commend the format completion though.

Appreciate the effort. You clearly got the joke, but that’s Beethoven and Stevie Wonder.
Pretty sure that’s Stevie Wonder lol
It is also Beethoven, not Mozart.
You are both wrong, these are pictures of Beethoven and Stevie Wonder, not the actual people.
Close enough! Tripped at the finish line
Tripped a little earlier. It’s not Mozart but Beethoven.
Thank you for explaining
Stevie Wonder🙄
Stevie Wonder😎*
Lol, I’ll remember that for next time.😉
No this is clearly a loss meme, just missing a panel
The xbox 360 still came with composite video cables and a scart adapter. That’s not THAT long ago.
Pretty sure Van Gogh wasn’t deaf in that ear though.
I think y’all are nitpicking this joke too hard
I have no clue…
Yellow is video, red and white are left and right audio
Channel 03 gang represent!
Screw channel 3, channel 4 is where it’s at.
Oh, it’s on. I bet you had a Sega. Pfft
Hilarious
Not even the SCART kids get it.
What’s SCART kids?
Ahh SCART, the beafiest connector. Feels like you’re plugging/unplugging a nuclear power plant.

This is RCA. Wasn’t composite early HD with RBG-RW?
You’re thinking of component. The two are (or were) frequently mixed up.
Yep, you’re right! Ah the memories.
A good way to remember is that RGB on the same wire is a Composite signal whereas when they have their own cables they are sent as individual Components.
Composite is Red, White(Sometimes black) and Yellow.
The best way to remember is Composite rhymes with shit.
RCA is just the connector, composite video is all the video signal chucked into one cable - component video splits it out into the colour components (getting the signal to that early HD level)

This is actually a pretty helpful diagram for when I inevitably forget which color does what
Please explain
These are older audio/video cables. Back in the days, before HDMI came around you connected your TV to other components (VCR, cable box, HiFi, sound system, etc.) with these cables. Red and White were the audio cables for left and right channels. Yellow was for the video feed.
So when we consider the artists in the meme: Van Gogh, only had one ear and both his eyes, so he has a single audio cable (mono instead of stereo) and a video cable.
Beethoven only has the video cable because he was deaf.
Stevie wonder has both audio cables but no video cable because he is blind.
I hope that makes more sense :)
https://en.wikipedia.org/wiki/RCA_connector
The one on the picture is called composite connector, compared to component, which used the same connector type but different colors codes. You had to be very careful where you plug them in your VHS player.
In composite the red and white plugs were the left and right sound, and the yellow the image. Van Gogh had one ear, so only one audio connector, Beethoven was deaf, so only yellow video,

My dude that is Stevie Wonder, not Ray Charles.
