Abstract

Authorization access controlled content exchange can be implemented, for example, in a multimedia content distribution environment when individual client devices are capable of storing content. A content index is maintained for each client device that reflects the content stored thereat. Predefined authorization access information for each relevant content item may be included in a content index entry corresponding thereto. A profile is maintained that includes predetermined authorization access information which indicates access rights. A search may be performed by and/or on behalf of a requesting client device for desired content with reference to authorization access information. A content transfer to the requesting client device from a target client device may be enabled if the predetermined authorization access information comports with the predefined authorization access information. Searches may be orchestrated or effectuated by the requesting client device or a head end of the multimedia content distribution system.
