Abstract
The present invention provides greater capability and flexibility than existing cable headends. Specifically, the invention comprises a modular design for a cable headend and a combiner component for cable headend. The invention is particularly useful in cable television program delivery systems transponding large numbers of digitally compressed program signals. The combiner allows cherry-picking of programs from transponded signals.
