ABSTRACT:
A method of preventing unauthorized recording of electronic media is described. The method is comprised of activating a compliance mechanism in response to receiving media content by a client system. The compliance mechanism is coupled to the client system. The media content presentation application is operable and coupled to the compliance mechanism. The method is further comprised of controlling a data output path of the client computer with the compliance mechanism. The method is further comprised of directing the media content via the data output path to a custom media device for selectively restricting output of the media content. The custom media device is coupled to the compliance mechanism and to the media content presentation application. The method is further comprised of preventing a recording application coupled to the client computer system from recording the media content file when recording violates usage restriction applicable to the media content.
