Technical stuff coming up, because I know and like to show off!
Teletext & Ceefax were, in a way, the first digital broadcasts. TV used to have 625 lines (405 in really old days) but there were a few unused lines both at the top and bottom of the screen. You may remember watching and seeing flashing white dots at the top. Well these dots were the coding for the teletext screen. Each page would be broadcast one at a time, scrolling through the pages one after the other. To receive a page you had to wait for it to be broadcast, hence the wait. The digital revolution brought to an end the 'spare' lines as digital speaks to each dot on a TV individually to tell it what colour to be.
But linking analogue with digital is easy. An mp3 is a digital audio file and uses less space than a normal wave audio because it removes those lines at the top and bottom because they aren't needed, thus the file is smaller (in a nutshell).
Happy to help.
