发明名称 DIGITAL CABLE HEADEND FOR CABLE TELEVISION DELIVERY SYSTEM
摘要 Several cable headend (34) configurations that utilize digital technology are disclosed. The present invention provides greater capability and flexibility than existing cable headends (34). Specifically, a modular design for a cable headend (34) and a combiner (104) component for cable headends (34) are disclosed. The invention is particularly useful in cable television program delivery systems transponding large numbers of digitally compressed program signals. The combiner (104) disclosed allows cherry-picking of programs from transponded signals.
