MEDIA FINGERPRINTING FOR CONTENT DETERMINATION AND RETRIEVAL

摘要

Audio fingerprinting and other media matching technologies can be used to identify broadcast media, such as 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 might receive information identifying a product in an advertisement, identifying an actor on screen in a movie at a particular time, or other such information. In some embodiments, the user can receive access to a digital copy of the captured media, such as the ability to download a copy of a program in which a user expressed interest. Since a user might capture media information after the point of interest, a device can buffer a window of recently captured media in order to attempt to identify the intended media.

主权项

1. A method for requesting information, comprising:
receiving media content streamed to a user device; playing said media content on said user device; capturing a portion of said media content, wherein said media content comprises first content and second content, wherein said first content is of interest to a user of said user device, and wherein said portion of said media content directly corresponds to said second content and not to said first content; assigning a time stamp to said captured portion corresponding to when said portion was captured; hashing said captured portion of said media content to obtain a hashed value; delivering said hashed value and said time stamp to a back-end server for identification of said media content in an initial request for supplemental information associated with said first content of interest to said user, wherein said back-end server is configured to identify said second content using said hashed value and correlate said second content with said first content using said time stamp; receiving for display from said back-end server a first option for selection that when selected requests first supplemental information corresponding to said first content of interest to said user; and receiving for display from said back-end server a second option for selection that when selected requests second supplemental information corresponding to said second content.
