Abstract: The disclosed technology relates to methods, devices, systems and computer program products that facilitate access to metadata associated with a content. In one example, a method is described that includes receiving a multimedia content at a receiver device, extracting a watermark message from a first segment of the multimedia content, using at least a portion of the first watermark message to obtain additional information regarding the first segment of the multimedia content that includes the first watermark message, and associating and storing one or more values of the first watermark message and the additional information. The method further includes repeating the above operations to extract additional watermark messages from additional segments of the content and to form a table or array of items that can be accessed by specifying the one or more values of the first watermark message or one or more values of the additional watermark messages.

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: Methods, devices, systems and computer program products facilitate accessing metadata associated with a primary audio visual content. Upon reception of a primary content, one or more watermark messages are extracted from the primary content obtain a server code and an interval code. A query to a metadata server is initiated based on the information obtained from the extracted watermark messages. In response to the query, service recovery information is received that includes information identifying one or more timed events, where each timed event identifies an operation to be performed at a corresponding instance in time as the primary content is being presented by the receiver device. One or more operations identified the timed events are initiated at the corresponding instance(s) in time.

Abstract: Methods, systems and devices enable enhanced delivery of metadata, as well as auxiliary programs and services associated with a primary content. In one method, a primary content with pre-existing watermarks is received at a content distributor device. The pre-existing watermark include specific fields that allow retrieval of a first metadata. The values and boundary locations of the symbols of the pre-existing watermark messages are determined, and symbols of a new watermark message are embedded in the primary content to render the pre-existing watermarks undetectable. The new watermark message includes symbol values that different from those in the pre-existing watermark messages and enable retrieval of a second metadata. Upon transmission of the primary content to a client device, detection of the new watermark message, and initiation of a request by the client device, access to the first or the metadata, as well as associated programs or services, are enabled.

Abstract: The disclosed embodiments relate to automatic content recognition and recovery of metadata associated with multimedia content. Embodiments include the use of audio watermarks, video watermarks or both to recover metadata. Embodiments also describe improved video watermark embedding techniques including quantization-based video watermarking in the spatial domain and quantization-based video watermarking in frequency domain, as well as improved video watermark detection techniques based on multiple video frames. Embodiments also include improvements to payload structure and improvements to payload recovery.

Abstract: Methods, devices and computer program products allow embedding and detection of watermarks into and from a multimedia content. One watermark embedding method includes selecting a content segment that lacks inherent features for embedding of watermarks without producing perceptible artifacts, and obtaining a first dither pattern corresponding to a first watermark symbol of a watermark symbol alphabet, where each symbol is associated with a particular dither pattern. Further, each particular dither pattern, upon combination with the multimedia content segment that lacks inherent features, produces a composite content segment without perceptible artifacts. By combining the first dither pattern with the multimedia content segment that lacks inherent features, a first composite content segment with the first embedded watermark symbol is produced. The detection of watermarks messages can be carried out quickly by examining a small portions of the multimedia because even the featureless content segments include embedded watermarks.

Abstract: Methods and devices are provided to embed a watermark message in a multimedia content to facilitate acquisition of associated information. One such method includes obtaining a server code that is assigned by a registrar entity and identifying a particular domain name that is registered to a registrant entity. Such a server code provides a mapping to an Internet address of a metadata server that includes information associated with the content. After obtaining one or more interval code, a watermark payload is formed that includes the server code and an interval code and embedded in the content. The identifies a particular segment of the content and upon distribution of such embedded content, a query based on the server code and one interval code allows metadata associated with the content to be acquired.
