Is there a specification for this? Like, say, at the backside of a cable box there exists a singular coaxial cable that is meant to be plugged directly in the back of the TV.
The TV must be set to a certain "mode" somehow ... I want to know the basic understanding of how the cable box sends video/audio signals through the wire, under what terms/specifications it does so, and how the TV "knows" what to do from there on.
This is a little vague, I know, but any basic answer regarding this will be appreciated.
I basically want to know how "picture data" and "sound data" get carried through that wire, and under what basic conditions this works(hobbyist engineer who is avid on learning all of this stuff, and implementing it).
I surmised that maybe the cable's video/audio circuit connects or transfers video/audio data to a specific form for the coaxial wire, and the TV can intercept and render that somehow? I don't know, this is why I ask, and this is an engineering site!
Thanks in advance for any help!
