What is the difference between analog cable, digital cable and HDTV?
Analog cable is the same signal that has been around for years. It is a relatively low bandwidth (as it is off-air), composite signal (all video and audio information in one). Digital cable is digitally encoded, standard definition video. Digital provides superior color resolution, particularly when used with component connections, and it is not susceptible to things like Radio Frequency and Electromagnetic interference that can affect analog signals. HDTV, like standard digital, is digitally encoded video, but at roughly 6 times the resolution of standard definition television. This provides you with clearer and crisper images plus wide screen viewing.
