<p>A store-and-forward architecture which stores and distributes information programs to subscribers includes: information warehouses which archive information programs and dispense information programs in segments to central offices in bursts; central offices which manage subscriber's requests for service and buffer segments of information programs for delivery to subscribers in real-time under the subscriber's interactive control; and customer premises equipment. The central offices employ CO buffers, and each CO buffer includes: processors (402, 405), for administering internal buffer operations and processing subscribers requests based upon the service presentation script and a program presentation map; interfaces (43, 46) for providing external access; busses (411, 412) for internal transport; buffer storage (403, 404) for storing segments of information programs; and memory storage (407, 413) for storing the script and map.</p> |
