Advanced Analog Box CANNOT have the same number of channels as the digital. The Advanced only refers to the features it can provide, e.g. Prevue guide and other services like the Interactive Channel, Wink, WorldGate, etc. By nature of the analog cable system, each channel would take 6 Hhz to transmit and the analog cable only has less than 1 GHz of capacity. Do the math and you know what I am talking about.

It is only with digital compression, cable can offer anywhere near the 500 channels we are talking about. The trouble with analog box and cable system is that it does not have the capacity to transmit the type of DATA (not video) down the line so the internet like services can be offered, unless something like the SRCM (or WorldGate) technology is used that either use the video frame or the VBI data (very narrow bandwidth).
