Abstract
On delivering a program on an On Demand method of a Cable TV, program reservation information is generated for each route of a communication line in a Cable TV center and is provided to a subscriber in order to restrain the number of digital lines in respect of the number of subscribers in a predetermined number and efficiently utilize equipment set in the center's side while maintaining the On Demand service to the subscriber. The subscriber thereby can recognize a reservation status of a program in respect of his or her own route and, if he or she desires simultaneous delivery of a program already reserved, an overlapping reservation of the program a third party reserved can be made. Communication lines can be efficiently utilized by simultaneously transmitting a program to the same communication line in this way.
