Most of them is supplying composite video and modern versions outputs nicam or A2 audio carrier, but then it gets more complicated because many of them uses different protocols of tuning: analog, I2C, or many variations of digital serial lines. analog mono signals are mostly analog voltage tuneable and datasheets are quite easy to get.
