Compare coaxial cable with twin-lead. In coaxial cable, there's a

Which is a
Balun in the true sense. A transfomer from the 75 Ohm
unbalanced cable to the 300 ohm balanced TV input.
Okay, now I'm curious. What's unbalanced about the one and balanced
about the other? (Of course, it quite possibly would be perfectly
obvious if I knew more about the relevant interfaces.)
