Abstract
A switching apparatus and method for routing RF scrambled signals. One of a plurality of scrambled RF television information signals is selected. A processor assigns an output carrier frequency. The selected scrambled television information signal is output by the switching apparatus on the assigned output carrier frequency. The plurality of scrambled RF television information signals is carried on an RF bus in the switching apparatus. The bus may consist of a plurality of cables. An RF switch connects a tuner to one of the cables. An amplifier is connected to the tuner. An amplitude information signal is decoded off the RF bus and is used for controlling gain of the amplifier. An up converter applies the output of the amplifier onto the assigned carrier frequency.
