The scanning is still there at the camera and display. The rest is magic done by very busy elves.
There is a vast amount of digital processing between the raw bitstream from the camera and you seeing it on your screen. The aim is to send as few bits as possible while still giving a good picture.
To start with the simple stuff. Are you familiar with SDI, the serial digital interface used in a studio environment? This is simply each pixel converted to 8 or 10 bit binary and sent serially down a single co-ax. That's 270Mb/s for 625 or 525, 1.5GB/s for 1080/50i etc and 3GB/s for 1080/50p etc.
