Default Pulling the HD signal from coaxial...

I don't know how the cable boxes work internally, but when you order HD service from a cable/sat. company and their HD digital signal comes into your reciever and out through the HDMI in the back...what is going on between the input and output points? Is the HD signal being converted or is the frequency of the HD signals in the coaxial cable being relayed to the HDMI output in a way that allows the AV quality to show up in HD on the TV screen? Thanks in advance for anyone's knowledge on the issue...
