Abstract
A multimedia information distribution system includes one or more servers, each server having access to a database storing multimedia information for distribution to subscribers, each of the servers connected to a network such as an Asynchronous transfer Mode (ATM) packet switching network, a number of switching points connected to the network, each switching point accepting digital information from the ATM network and under the control of a resource manager providing one or more multimedia information streams through a coaxial switching network to one or more modems, wherein each modem is connected to a user's terminal by existing transmission media such as telephone twisted pair wires using Asynchronous Digital Subscriber Line (ADSL). In an alternate embodiment, the digital switching may be distributed using a hybrid fiber coaxial (HFC) cable technique to extend effective range of transmission.
