Does video from the backup camera or side mirror camera travel to the (NAV) display via the CAN bus or some other mechanism?

I'm really curious if you can get access in some way to that video - or replace it. (E.g., grab it from the bus and put it on your own display with your own overlays. Or replace it with a stream from a different camera.)

Update: I should have made this clear originally: I'm speaking of video from manufacturer standard equipment (the backup camera and side mirror camera are standard features of the car).

I've shopped for a rear-vew camera for my car in the past, and one thing you see time and time-again are standard RCA-style video jacks like the picture below from an AliExpress seller:

You can easily find other examples by searching for OEM camera kits for cars that had a camera as an option. The cameras all have at least a power plug and an RCA video jack. Many of these cars will already have the wiring in the trunk - they just don't have the actual camera.

Because it uses this ubiquitous 2-wire analog video protocol, you can easily intercept, split, or replace the video stream with common, inexpensive video devices.

Also, another bit of info you might find interesting - in many of the aftermarket "basic" cameras the parking lines that are displayed are generated in-camera rather than being overlayed by the video display. Some nicer, OEM units have animated lines that are computer generated in the display.
