<p>A multimedia information delivery network system (10) is disclosed for delivering multimedia programs to a plurality of users (12) at user-selected times. The network includes a wide area transmitter (14) for transmitting the multimedia programs. Additionally, the network includes a plurality of network servers (16) for receiving the programs and for selectively caching the programs for retransmission to downstream network servers (18) and/or directly to one or more users (12) at the user-selected transmission times. A scheduler (36) receives the user-selected transmission times and, in response thereto, establishes a network server path by which the multimedia program is efficiently delivered to each user (12) at the respective user-selected time.</p> |
