1. A system for routing an output containing a user-selected program to at least one of a plurality of units, each unit having at least one communications interface, the system comprisingat least one demodulator for demodulating at least one input signal,at least one processor for processing the at least one input signal by one or more of matching an impedance of the input signal to an output impedance, raising a baseband of the input signal, equalizing high frequency components, increasing a level of chroma, converting a plurality of signal formats into a common format for routing, optimizing frequency allocation, and selecting an appropriate modulation technique,a server inserting or substituting, or both, programming other than a user-selected program into the output containing the user-selected program, based on information relating to the user, to thereby transmit in the output said programming other than the user-selected program to the user before, during or after the user-selected program, or any combination thereof, andat least one device for routing the user-selected program in Internet protocol to the at least one communications interface within the one of the plurality of units, wherein the at least one communications interface receives the user-selected program and the programming other than the user-selected program for transmission to at least one receiving device in the one of the plurality of units.
