ABSTRACT:
Each of a plurality of households includes a channel substitution unit which receives a normal spectrum of television channel signals and at least one substitute channel signal. The substitution unit of each household, upon command from a control arrangement, replaces a channel of the normal television channel spectrum with the substitute channel and distributes the resulting spectrum, comprising the original normal spectrum of television channel signals with one substituted channel, over a distribution medium such as an in-house distribution cable.
