Abstract: Methods, devices, systems and computer program products facilitate embedding and extraction of transactional watermarks into and from a video content. One such method includes selecting a first number of frames from a video content and performing temporal and a spatial psychovisual analysis on the selected frames. For each selected frame, at least one area for insertion of watermarks is identified. A first and a second watermark symbol is embedded separately in the identified area(s), and the embedded frames are re-encoded to obtain a first and a second alternative data. An inserter manifest is formed that includes the first and the second alternative data to enable insertion of a watermark into the video content by selecting one or the other of the first and second alternative data for insertion into the video content.

Abstract: Methods and devices are provided to obtain associated information for a multimedia content. One such method includes receiving a content at a receiver device equipped with a watermark detector, performing watermark detection on the received content to extract a payload of an embedded watermark. The payload comprises a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier. The first field provides a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload. In this method, based on the detected watermark payload, a query is formed and transmitted to a server identified by the Internet address, and a response to the query is received from the server that includes metadata associated with the content.

Abstract: Methods, devices, systems and computer program products utilized watermarks that are embedded in a content to facilitate content access, and to enhance a user's experience by allowing the user to explore additional options for obtaining the desired content and related items of interest. In one method, an indication for an access to a content is received that includes one or more copy management watermarks and one or more enhanced payload watermarks. At least one copy management watermark and at least one enhanced payload watermark are extracted from the content. Upon a determination, based on the at least one copy management watermark, that access rights to the content is restricted, the enhanced payload watermark is used to present one or more alternative options.

Abstract: A method for embedding video watermarks. Areas of poor visual quality in a video content having embedded watermarks ar determined. The watermark symbols replace pixels in the video content with pixels in which the luma values are modulated such the luma value for a 0 bit renders as black and the luma value for a 1 bit renders a shade of gray. The luma value for the 1 bit level is reduced in those areas determined to have poor visual quality. Areas of poor visual quality may be determined by analyzing the luma values of pixels of the video content immediately adjacent to and below a particular watermark symbol to derive an adjacent brightness parameter that represents the perceptual brightness of the surrounding video content. The reduction of the luma value may be achieved by setting the 1 bit luma for a particular watermark symbol to be perceptually less bright than the adjacent brightness parameter.

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, 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, devices and computer program products allow improved synchronization among multiple contents. One disclosed method includes receiving a first and a second content and performing watermark extraction to recover a first timecode as part of a watermark embedded into a segment of that content. The first timecode conforms to a first type of timing system. Next, a timing system associated with the second content is determined, and a mapping is obtained that allows timecode conversion between the first and the second timing systems. Using the mapping to synchronize the presentation of the second content with that of the first content. Thus synchronization of multiple contents is properly maintained even when processing operations such as format conversion and transcoding cause metadata streams that carry timing information to be removed.

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.
