How digital cable TV works?

In: Cable Television [Edit categories]

Answer:

A signal is sent through the cable at a much higher frequency than regular cable. Additional data is sent in this signal to support the original audio and video signals to ensure that they are received in much better quality than analog signals. This additional data and the type of signal sent is what allows the quality to be so much better than older analog signals.
