The disclosed embodiments relate to an apparatus (600) and a method (700) for re-synthesizing signals. The apparatus (600) includes a receiver (604a-c, 610a-c) 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 (640, 67Oa-N, 680) 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 (700) involves receiving a first signal (702) having a plurality of different program streams in different frequency channels, selecting (706) a set of program streams from the plurality of different frequency channels, combining (712) the set of program streams to form a second signal, and transmitting (720) the second signal. |
