Abstract
Abstract This specification discloses a method of storing, transmitting and selectively retrieving a large quantity of information such as audio signals over a wide bandwidth communication system such as television. An entire block of such information is recorded at a real-time rate, rapidly transmitted in its entirety at a greatly accelerated rate by a relatively wide bandwith signal, received and re-recorded at substantially the same accelerated rate for subsequent reproduction of the audio information at a real-time rate. Several specific methods and apparatus are disclosed for carrying out these concepts.
