Abstract

Methods, devices, systems and computer program products utilized watermarks that are embedded in a content to facilitate content access, and to enhance a user's experience by allowing the user to explore additional options for obtaining the desired content and related items of interest. In one method, an indication for an access to a content is received that includes one or more copy management watermarks and one or more enhanced payload watermarks. At least one copy management watermark and at least one enhanced payload watermark are extracted from the content. Upon a determination, based on the at least one copy management watermark, that access rights to the content is restricted, the enhanced payload watermark is used to present one or more alternative options.

Dependencies are inferred from the claim text.
