Abstract: Systems and methods are provided for identifying a video object using digital fingerprints. The digital fingerprints are generated from information extracted from the video object including encoded video. The digital fingerprints can be calculated in a manner that permits identification of both the video object and operational characteristics of the video object based on matching calculated digital fingerprints with known fingerprints of known video objects. Systems and methods are described that allow a DVD to be uniquely identified and identify whether the DVD is original, copied or pirated. Systems and methods are described for computing digital fingerprints from strings of bits in which certain additional data is optionally embedded. Systems and methods are described that permit media players to access known signatures of known video objects maintained on one or more databases and to identify video objects presented for playing on the media player.

Abstract: Method and system for discovering and identifying a video object. The method includes crawling at least one predetermined website, discovering at least one video link at the predetermined website, processing information associated with a first database for storing one or more video links, and determining whether the discovered video link was already discovered before based on at least information associated with the first database. Additionally, the method includes, if the discovered video link is determined not to have been discovered before, updating the first database based on at least information associated with the discovered video link, downloading at least one video object based on at least information associated with the discovered video link, and processing information associated with the downloaded video object.

Abstract: A method and system for generating a spatial signature for a frame of a video object. The method includes obtaining a frame associated with a video object, and dividing the frame into a plurality of blocks. The plurality of blocks corresponds to a plurality of locations respectively, each of the plurality of blocks includes a plurality of pixels, and the plurality of pixels corresponds to a plurality of pixel values respectively. Additionally, the method includes determining a plurality of average pixel values for the plurality of blocks respectively. Each of the plurality of blocks corresponds to one of the plurality of average pixel values. Moreover, the method includes processing information associated with the plurality of average pixel values and determining a plurality of comparison values for the plurality of blocks respectively based on at least information associated with the plurality of average pixel values.

Abstract: Systems and methods are described for publishing, searching, retrieving and binding metadata with a digital object. A content-based ID can be employed to uniquely identify a digital object and associate metadata with the digital object. Content-based IDs can be a unique code, or a string of bits or some other unique identifier that can be consistently recalculated from the digital object and can serve as a permanent identifier for the digital object. Systems and methods are described for publishing metadata by wrapping metadata with a content-based ID for a digital object. According to certain aspects of the invention, the metadata can be published in a syndication feed including an RSS feed. An extension to syndication feeds is described that includes a tag for publishing metadata about a digital media object with a more generalized content-based ID.
