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.

[–] normalmighty 17 points 11 months ago (1 children)

That makes so much sense! I never understood it, and it became irrelevant before I worked it out.

[–] [email protected] 9 points 11 months ago

It's so funny, I had the same reaction! Never quite understood it, just switched plugs until it worked. Then it got phased out and... decades later a meme brings light to my confusing childhood!

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.

Thank you. Guess I must be a HDMI kid, who would have known.

Pretty sure Van Gogh wasn't deaf in that ear though.

Things probably sounded weird there though. Lots of whooshing.

[–] FarFarAway 8 points 11 months ago (3 children)

Definitely. A piercing in my conch, was enough to give me some mildly annoying tinnitus for years.

Can't imagine if my ear was just...gone.

Weird that your vagina would do that

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.

[–] [email protected] 11 points 11 months ago (1 children)

Scart was amazing. RGB, composite, component, audio. All in one cable. Granted that cable and connector were enormous, but one cable nonetheless.

[–] [email protected] 14 points 11 months ago (1 children)

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.

This is actually a pretty helpful diagram for when I inevitably forget which color does what

[–] [email protected] 27 points 11 months ago (1 children)

Not even the SCART kids get it.

[–] [email protected] 26 points 11 months ago (1 children)

Ahh SCART, the beafiest connector. Feels like you're plugging/unplugging a nuclear power plant.

I remember Christmas day getting a ps1 pulling out the cables and realizing that my tv didn't have the right ports and had to wait a couple of days to play it since the stores where closed and I couldn't buy one of those cables that connected to where the cable tv goes . Then getting stuck at the first section of tomb raider 2 for the next couple of days ...

This is RCA. Wasn’t composite early HD with RBG-RW?

[–] [email protected] 20 points 11 months ago (1 children)

You're thinking of component. The two are (or were) frequently mixed up.

[–] [email protected] 5 points 11 months ago (1 children)

Yep, you’re right! Ah the memories.

[–] [email protected] 6 points 11 months ago (1 children)

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.
