Abstract
A plurality of television signals are transmitted and selectively received on a single television channel allocation. Headend apparatus compresses a set of television signals, such as a main program signal and a plurality of different demographically targeted commercials. The plurality of compressed television signals are combined into a combined signal for transmission on a single television channel allocation. A receiver receiving the combined signal identifies characteristics of a television viewer, and selects a particular one of the compressed television signals from the received combined signal depending on the viewer characteristics. The retrieved signal is decompressed for use by a video appliance.
