How does RCA data transmission work?

Question

Iron

There is a need to process video data from an RCA cable (tulip) using an Arduino-type microcontroller, but I could not find a specification for exactly how the picture is transmitted.
Roughly speaking, the task itself is to form an image based on the signals received from the tulip.
Throw, please, links to a description of how it works, or to ready-made libraries or something like that. Thanks :)

Answer 1

It is very difficult to work on 8bit video controllers. There is no necessary peripherals, no speed.
The standard is called composite video https://ru.wikipedia.org/wiki/%D0%9A%D0%BE%D0%BC%D... You
can still generate a simple image, examples can be found. As for the capture, I'm not sure what happens on such stones.

Answer 2

No way. The computing resources of the arduino are not enough to process streaming video.
