Abstract: Methods, devices, systems and computer program products use watermarks to allow a user to explore to obtain desired content and related items. One device includes an extended payload (EP) watermark extractor coupled to an audio input and to an enhanced response coordinator (ERC). The device also includes a copy control information (CCI) watermark detector coupled to the audio input and coupled to a copy management compliance logic component. The ERC is further coupled to the EP extractor and to a communication component. The device also includes a referred sale logic component coupled to the ERC to receive referral information that is indicative of one or more alternative options. The device further includes a digital service provider (DSP) client component coupled to the referred sale logic and also coupled to the communication component that allows the DSP client to communicate with DSPs and to receive one of the alternative options.

Abstract: A system and method for tracking the state of a television in an HDMI environment using analysis of the bi-directional HDMI CEC channel. This information may be used to determine if the television has been turned on or off, and also to determine if a streaming media player has been selected for display. In response to a determination that the television has been turned off, or that another input has been selected for display on the television, the stream may be turned off or other actions may be taken. By turning off the stream when it is not being viewed, unnecessary network usage and power consumption is avoided. Another advantage of the disclosed system and method is that advertisers may avoid streaming ads that are not viewable.

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: 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.

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: Method, devices, systems and computer program products are described that improve speed and accuracy of watermark detection from multimedia content, and allow faster and better content recognition. One technique for improving detection of boundaries of an embedded multimedia content segment includes detecting a synchronization header and a full watermark from the multimedia content, constructing a predicted watermark segment that is positioned at a predicted distance from the synchronization header, and comparing the group of candidate watermark symbols obtained from the multimedia content to the first predicted watermark segment to obtain a match. The disclosed techniques enable extraction of watermarks from short content segments, and can utilize a shortened payload design to establish media time during content usage.

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.

Abstract: Methods, devices, systems and computer program products are provided for embedding and detection of a watermark message to and from an object-based composite content. One exemplary method includes for embedding a watermark message in an object-based composite content includes designating a plurality of content objects for carrying the watermark message comprising one or more watermark symbols in the composite object-based content that is generated according to an object-based encoding scheme. The method also includes obtaining a mapping of each watermark symbol to a temporal or spatial position of one or more of the designated content objects in the composite content, and embedding each watermark symbol by including each of the one or more of the designated content objects in the composite content in conformance with the temporal or spatial relationship provided by the mapping.
