Definitions

  • the present invention relates generally to techniques for handling metadata for a digital object and more particularly to methods and systems for publishing, searching, retrieving, and binding metadata for a digital video object using content-based IDs that are computed from the digital video object.
  • Metadata data that describes another set of data.
  • Digital objects particularly digital media objects such as picture and video can often be associated with metadata.
  • metadata for a digital object can include data that describes the content in a digital object, and data that describes the attributes of the digital object.
  • metadata is often essential in providing a richly informative and user-friendly media software and service.
  • Metadata may be embedded in or provided separately from a digital object. In both cases the binding of the metadata with a digital object is generally artificial and can be easily broken because metadata is not an integral part of the media data.
  • an MP3 music file may contain an embedded ID3 metadata tag to describe title, artist, and copyright holder of encoded music, but the tag can be removed from the MP3 file without affecting the integrity of the MP3 and playback of MP3 music is unaffected by presence or absence of the tag.
  • Metadata is often detached from the digital object it describes.
  • Embodiments of the invention provide systems and methods for publishing, searching, retrieving and binding metadata with a digital object.
  • Certain embodiments of the invention employ a content-based ID to uniquely identify a digital object and associate metadata with the digital object.
  • a content-based ID can be a unique code, a string of bits or some other unique identifier that can be computed from the digital object itself.
  • the content- based ID can be consistently recalculated from the digital object and therefore can serve as a permanent identifier for the digital object.
  • aspects of the present invention facilitate publishing, searching, retrieving and binding of metadata to its associated digital object.
  • publishing metadata comprises wrapping metadata with a content-based ID for a digital object in a Really Simple Syndication feed.
  • Certain embodiments of the invention employ an extension to syndication feeds that include a tag for publishing metadata about a digital media object with a more generalized content-based ID.
  • searching metadata associated with a particular digital object can be performed on a local hard disk drive of a computer or over a network such as a local-area network (LAN) or the Internet.
  • a search may be initiated and executed automatically on a local computing device such as a computer or a digital video recorder, or among several computing devices over a network. Searches may also be initiated and executed on an Internet search engine.
  • a metadata search based on a selected content-based ID can discover all metadata that is associated with the selected content-based ID.
  • the metadata can be retrieved and bound to the associated digital object based on the content-based ID of the digital object.
  • a table used to record binding relationship may be implemented such that all video objects and their associated metadata or links to metadata are stored in a single table where different objects are identified by their content-based object IDs.
  • the binding relationship may be stored in a relational database.
  • Figure 1 is a flowchart illustrating one example of a process according to certain aspects of the invention.
  • Figure 2 is a flowchart illustrating one example of a Web search according to certain aspects of the invention.
  • Figure 3 is an example of a Web page returned by a search engine in response to a user query containing "Air Force One.”
  • Figure 4 is a block drawing illustrating a system according to certain aspects of the invention.
  • Embodiments of the invention provide systems and methods for facilitating automatic publishing, searching, retrieving and binding of metadata with a digital object.
  • digital object may be interchangeably used to refer to a digital file or a bitstream.
  • a computer file stored on a hard disk drive and a broadcast or streamed video bitstream may both be described as digital objects.
  • Certain embodiments of the invention employ a content-based ED to uniquely identify a digital object and associate metadata with the digital object.
  • a content-based ID 3 also known as "digital fingerprint" or "fingerprint” can be a unique code, a string of bits or some other unique identifier that can be computed from the digital object itself.
  • a content- based ID for a digital object such as a computer file can be its binary hash.
  • the MD5 hash specified by RFC 1321 may be employed.
  • Certain embodiments of the invention can use the digital fingerprints described in U.S. Non- Provisional Patent Application Serial No. __/ , filed February 27, 2007, entitled
  • publishing metadata comprises wrapping metadata with a content-based ID for a digital object in a Really Simple Syndication ("RSS") feed.
  • RSS is an example of content syndication on the Web using an XML file format.
  • RSS started in news headline syndication, current RSS feeds can carry a wide array of content types, including news headlines, forums and blogs, software announcements, as well as metadata.
  • RSS has become particularly popular in blogging and podcasting services in recent years and an extension known as Media RSS or MRSS has been made for syndicating media content.
  • the MRSS specification defines a ⁇ media:hash> tag that may be viewed as a content-based ID.
  • a binary hash is not a good identifier because of its sensitivity to even a single bit change in the digital object.
  • Certain embodiments of the invention employ an extension to MRSS that includes a new ⁇ media:ID> tag in order to use MRSS to publish metadata about a digital media object with a more generalized content-based ID.
  • a movie review is contained in metadata that is tagged for a digital object with
  • the ⁇ media:ID> tag is used simply for announcing the digital object ID with which the piece of metadata is associated.
  • the qualifier 'algo "vobile'" specifies the algorithm by which the object ID is generated. This is necessary because that like hashing, a content-based object ID may be generated by different methods; the 'algo' qualifier resolves the ambiguity.
  • searching metadata associated with a particular digital object can be performed on a local hard disk drive of a computer or over a network such as a local-area network (LAN) or the Internet.
  • a search may be initiated and executed automatically on a local computing device such as a computer or a digital video recorder, or among several computing devices over a network. Searches may also be initiated and executed on an Internet search engine.
  • user actions may initiate a search where user actions can include activating an application, causing an application to be executed, opening or attempting to open a digital object, inserting a DVD or other storage and copying a digital object.
  • FIG. 1 provides a flowchart for one example of a metadata search according to certain aspects of the invention.
  • a metadata search can be initiated and executed on a local computing device such as a personal computer or other device.
  • video jukebox software that subscribes to metadata feeds from the Internet may be configured to scan a local hard disk drive to find and import a video object file. If a new video object is discovered at step 102, the process continues. At step 104, a content-based object ID can be computed for the newly-discovered video object. Then at step 106, the computed object ID may be used to search the local disk for items, files and objects that are associated with the object ID or include the object ID. If metadata is found at step 108, then the metadata can be bound with the video object at step 109.
  • a network search for metadata associated with the object ID can be conducted.
  • the search may include local networks, the Internet and other networks. If metadata is found at step 112, then the metadata can be bound with the video object at step 113.
  • Metadata can be bound to a video object (and other digital objects) by linking the metadata to the video digital object. Binding need not include attaching the metadata to the digital object in a file or bitstream. Binding can be achieved by referencing both the digital object and the associated metadata to a content-based object ID.
  • metadata can be bound to a digital object by creating a table named or otherwise identified by the object ID created at step 104.
  • Table 1 illustrates a table that records bindings between metadata and a video object.
  • two pieces of metadata are found and bound.
  • the first item identifies a piece of metadata stored on a local hard drive and records its file path.
  • the second item identifies a piece of metadata that resides on a remote server and records its URL.
  • a table used to record binding relationship may be implemented such that all video objects and their associated metadata or links to metadata are stored in a single table where different objects are identified by their content-based object EDs.
  • the binding relationship may be stored in a relational database. Other methods of recording and maintaining links based on content-based object ID to bind digital objects and associated metadata are contemplated. The examples provided above are presented for illustrative purposes only.

  • the metadata search is initiated and executed on a search engine such as Google, typically in response to a user query.
  • a user enters a query to the search engine.
  • the query is the name of a movie title: "Air Force One.”
  • the search engine returns one or more pages of search results (hits).
