Abstract: Methods, devices and computer program products facilitate enhanced use and interaction with a multimedia content through the use of tags. While a content is being presented by a device, a content identifier and at least one time code associated with one or more content segments are obtained. One or both of the content identifier and the time code can be obtained from watermarks that are embedded in the content, or through computation of fingerprints that are subsequently matched against a database of stored fingerprints and metadata, The content identifier and the at least one time code are transmitted to a tag server. In response, tag information for the one or more content segments is received and one or more tags are presented to a user. The tags are persistently associated with temporal locations of the content segments.

Abstract: The disclosed embodiments relate to methods, devices and computer program products that enable watermark-based metadata recovery for content with multiple alternative components. The content can, for example, be included in broadcast television services which include multiple alternative audio and video components, only a subset of which may be presented by a given receiver at a given time. The disclosed techniques, among other features, enable broadcasters to deliver different services to different customers by using different watermarks into the feeds they provide to multichannel video program distributors (MVPDs). For instance, coincident audio and video components are embedded with different watermark payloads.

The IP address corresponds to at least one of the server codes detected from the plurality of watermark messages. According to the above method, the metadata is requested from the server having the server IP address, and a response including the metadata associated with the multimedia content is received.

Abstract: Methods and devices are provided to facilitate acquisition of information associated with a multimedia content through embedded watermarks. One such method includes obtaining a server code for embedding into a content. The server code identifies a particular domain name registered to a registrant entity and provides a mapping to an Internet address of a metadata server. Upon receiving an indication that a trigger event is associated with a particular segment of the content, a first watermark payload is formed and embedded in the content. The watermark payload includes the server code, an interval code and a first trigger value. The interval code identifies the particular content segment and the first trigger value indicates that additional information associated with the particular segment is. Detection of the first trigger value from a subsequently distributed content enables a query to the metadata server for acquisition of metadata.
