Abstract: A content exchange service facilitates communication between, and production of content by, holders of rights in content titles and producers of content. The content exchange service receives content profiles from various rights holders and surfaces the content profiles to producers for purposes of soliciting auditions to produce the content subject of the content profiles in an alternative form. The rights holder can review the auditions submitted by producers and establish communication with the producer of the audition the rights holder liked via the content exchange service. The content exchange service can then facilitate negotiation of an agreement between the rights holder and the producer for production of the content in an alternative form. Following finalization of the agreement, the producer may submit a complete production of the content in the alternative form to the content exchange service, which in turn presents the complete production to the rights holder for approval.

Abstract: The present invention includes a system for transmitting, receiving, storing and replaying a user selected program, which has a service center including an electronic user accessible interface and an electronically stored library of user selectable programs. It includes a base unit having an electronic interface that is electronically interconnectable with the service center's user interface to receive the user selected programs, and an output port that interconnects the base unit with a cassette.The cassette includes a data input port for the reception of electronic data representing the selected programs from the base unit output port, and a memory storage to store the electronic data. The cassette is insertable into and interconnectable with electromechanical components of a standard magnetic tape audio cassette player whereby the stored program selections are transmitted from the cassette to the audio cassette player for broadcasting.
