Abstract
Methods and apparatus for identifying media are described. An example method includes determining application identification information for a media presentation application executing on a media device, determining a first watermark for the application identification information from a lookup table, requesting media identification information for media from the media presentation application, determining a second watermark for the media identification information from the lookup table, inserting the first watermark in the media prior to output of the media by the media device, and inserting the second watermark in the media prior to the output of the media by the media device.8,874,575, "Media fingerprinting for social networking," assigned to Sony Computer Entertainment Inc.

Abstract
Audio fingerprinting and other media matching technologies can be used to identify media, such as movies, television shows, and radio broadcasts. A user device can record image, audio, and/or video information and upload information to a matching service that is able to use matching technology to identify the media and provide supplemental content or information to the user. The user then can share this information with other users, such as by uploading to a social networking site or passing the information to peers on a peer network as part of a container. Users can have the ability to add tagged content, provide comments and ratings, and otherwise interact based at least in part upon the tagged media content.
