The center pin wire (white insulated) is the video signal the outer conductor (shield/bare wire) is the ground. Since a video signal is a complex high frequency AC Signal there is no positive or negative. A standard NTSC or EIA/RS-170 signal in consumer equipment in the US is 1V PP. Sent from my iPhone

I cut one end off a generic yellow-tipped RCA wire and stripped back the insulation.
Insider there's one insulated wire (yellow) and one bare copper wire.
Which is the positive/negative?
Rest assured, I'm experimenting on my own Pi, not the museum's. :)
