Abstract

See full text

A secure music distribution system securely distributes digital products such as music, video, and/or computer software along with related media over a public telecommunications network, such as the Internet, employing a client-server architecture. The digital products are stored and controlled by a content manager computer system and are sold by separate merchant computer systems. The secure music distribution system includes a music distribution center which operates with any number of client systems and with any number of merchant systems. The music distribution center includes a content manager and at least one delivery server. The content manager maintains a media information database, a master media file system, and a transaction database. In addition, the music distribution center interfaces with a media licensing center, which in turn communicates with one or more distributed rights agent servers and the merchant servers. The merchant server executes in a merchant computer system, which also includes an HTTP (HyperText Transfer Protocol) server. The merchant servers interface with various payment processing systems. The client systems include a media player and a Web browser. Additional delivery servers and media licensing centers operate independently and externally to the music distribution center and interface with the music distribution center.
