MULTIPLE REDUCED-BANDWIDTH PROCESSING PATHS TO ACHIEVE A FULL AND CONTINUOUS OUTPUT BAND FOR MULTIPLE-CHANNEL CATV UPCONVERSION

摘要

A method of channel processing is provided wherein multiple reduced-bandwidth "processing blocks" may be combined at RF to allow for the continuous and flexible placement of multiple-channels across the full or partial CATV output band. Each reduced-bandwidth processing block is associated with a fixed-frequency upconversion. In order to allow for continuous agile channel placement, the processing blocks overlap one another in frequency at RF. In the case where it is not necessary that the full CATV band be available to the combined output, the number of required processing blocks and upconversion paths is reduced and individual processing blocks and upconversion paths may be used to cover multiple non-contiguous frequency bands.
