ABSTRACT:
The invention provides a method and apparatus for transmitting information recorded on information storage from a central server via a high data rate digital telecommunications network to subscribers connected to the network. The telecommunications network is capable of two-way communication. The central server includes a central communication interface connected to the network, a magazine containing a very large number of disks, disk players, a controller for transfer of the disks between the magazine and the disk players, a central computer, a memory for storing information relating to the locations of the disks, and a multiplexer. Each of the subscriber stations includes a communication interface connected to the network, a computing terminal, a demultiplexer, a data rate expansion circuit, a digital-to-analog converter, and a transducer for converting analog signals into humanly perceptible signals. In one example, the invention provides for the delivery to a subscriber of a personalized sound program selected from a large directory of available selections.
