[PLUG] How Do They Put Artwork on CD?

[Casey Bralla <MailList@nerdworld.org>]

Not actually a Linux question, but I'm sure the CD player in my car is running 
Linux, so....


I put a commercial music CD into my 2015 subaru's CD player, and a small 
version of the cover art appeared on the display screen.  How the heck did it 
do that?   Is it encoded in the CD along with track text info?  I had thought 
the car was downloading artwork via satellite, but I let my satellite 
subscription (included with the car) lapse 6 months ago.

I've Duck-Duck-Go'd this, but can't find anything other than putting artwork on 
CDs.

Anybody know how it's encoded on the disk?
