The difference is in the connectors. The top left is a push-on type, while the bottom two are threaded.
What the signal is, extremely highly depends on what those internal cables are connected to. They can offer anything from UHF TV signal, radio, video, antenna to whatever else which can use a 75ohm single coaxial wire. To only way to find out for sure is to follow the cable and look where it goes... and hoping something is labelled. They might as well all be directly connected to eachother behind the socket plate (although I doubt that).
Bottom line is that you can't judge from those connectors what the signal is.
