Abstract

This invention makes use of existing visible and hidden watermark technology to 1) identify content, 2) provide a modicum of metadata (actors, director, year released, etc.), 3) I-frame index number when no other information available, 4) time of distribution, 5) the distribution channel (service provider), and 6) URL to content provider website. Some or all of the above data can be extracted from the watermark by the rendering device with an Internet connection, and then used in combination with auxiliary information and purchase opportunities to the user from websites. The invention relates to a method of extracting information from the watermark embedded with the content and providing additional web-based ancillary information based on the extracted information. The method extracts information such as content identification, metadata (actors, director, year released, etc.), I-Frame index number, time of distribution, distribution channel (Service provider) and URL to content provider's website from the watermark embedded with the content. The additional web-based information enhances the viewer's experience.

This invention makes use of existing visible and hidden watermark technology to 1) identify content, 2) provide a modicum of metadata (actors, director, year released, etc.), 3) I-frame index number when no other information available, 4) time of distribution, 5) the distribution channel (service provider), and 6) URL to content provider website. Some or all of the above data can be extracted from the watermark by the rendering device with an Internet connection, and then used in combination with auxiliary information and purchase opportunities to the user from websites.

The invention relates to a method of extracting information from the watermark embedded with the content and providing additional web-based ancillary information based on the extracted information. The method extracts information such as content identification, metadata (actors, director, year released, etc.), I-Frame index number, time of distribution, distribution channel (Service provider) and URL to content provider’s website from the watermark embedded with the content. The additional web-based information enhances the viewer's experience.

Issues or problems solved by this invention: How to identify uncompressed, streaming digital content without other information.

How did others try to address these issues/problems: Watermark technology typically identifies content, but usually identifies rights and not the additional metadata listed in the description of this innovation. Also, it is believed that watermark technology has not been used as disclosed in this invention as a way to access metadata for that content over the Internet.

Background: Watermarks are becoming a common method for broadcasters to mark the content they broadcast. These are typically both visible, in the form of logos, and hidden (not perceptible to the viewer). Content generators are increasingly relying upon non-visible watermarks to uniquely ID their content when it is used illegally. Typically "bots" are sent out on web exploring...
