The disclosed embodiments relate to an apparatus and a method for re-synthesizing signals. The apparatus includes a receiver for receiving a plurality of digitally multiplexed signals, each digitally multiplexed signal associated with a different physical transmission channel, and for simultaneously recovering from at least two of the digital multiplexes a plurality of bit streams. The apparatus also includes a transmitter for inserting the plurality of bit streams into different digital multiplexes and for modulating the different digital multiplexes for transmission on different transmission channels. The method involves receiving a first signal having a plurality of different program streams in different frequency channels, selecting a set of program streams from the plurality of different frequency channels, combining the set of program streams to form a second signal, and transmitting the second signal.
