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.
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 :(
Oh, they did the same with stereo radio.
