Abstract: A digital content delivery system, a digital content delivery method, a program for executing the method, a computer-readable recording medium storing thereon the program, and a server and a client for it. The digital content delivery system delivers a digital content via a first network (12) and a second network (22). A server (14) is connected to the first network (12), and clients (20) each of which receives a digital content and displays or reproduces it are connected to the second network (22). The server (14) divides a digital content it has into a plurality of packets and sends the packets, which are minimum units for configuring the digital content, to the second network (22). Each of the clients (20) includes means for allowing the client (20) to hold a digital content using the packets, which are minimum units, received by the client (20) from the server (14) and the packets received from another client of the second network.

Abstract: The digital contents distribution system of the present invention distributes digital contents through first and second networks 12 and 22. A server 14 is connected to the first network 12, and clients 20 for receiving and displaying or reproducing the digital contents are connected to the second network 22. The server 14 divides digital contents held therein into a plurality of packets, and transmits packets of a minimum unit for constructing the digital contents to the second network 22. The clients 20 include means for holding the digital contents therein by use of the packets of the minimum unit received from the server 14 and packets received from other clients constructing the second network.
