ASYNCHRONOUS COMMUNICATION SYSTEM

摘要

A data storage system, and associated asynchronous communication system and method are described. The data storage system includes data storage means ( 46 ) for storing data and an asynchronous transmitter/receiver ( 45 ) arranged to communicate over an IEEE 1394 network ( 30 ). The data storage means ( 46 ) is arranged to accept inputs and to output via an access limiting connector. At least selected data files of the stored data include copy control limiting information, a request for a data file including the copy control limiting information from the data storage means being permitted by the access limiting connector only upon successful authentication. A permitted requested file being encrypted and transmitted asynchronously by the transmitter/receiver ( 45 ).
