More and more, old-style analogue cable is falling by the wayside – many cable providers have even turned it off altogether. It’s being replaced by digital cable, the new generation of cable that allows up to ten times as many channels to be sent down that same line, with a much higher picture quality to boot. Instead of sending those old-fashioned radio waves down the line, digital cable providers send compressed, digital data, much like an Internet connection (in fact, in many cases, they do just go ahead and use a cable Internet connection for the TV signals). As each channel takes up less space, many more channels can be put onto the service. There is also scope for all sorts of interactive services, as data can be sent both ways through the line.
