A method of processing information in a digital receiver connected to an external input source includes receiving uncompressed data of a broadcast service from the external input source, the broadcast service delivered based on either a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol; extracting an audio watermark from the uncompressed data; making a request to a specific server using domain type and server code of the audio watermark to form a first URL; receiving a recovery file including a second URL used to retrieve signaling files needed to access and present a supplementary content; retrieving the signaling files using the second URL in the recovery file; and presenting the supplementary content based on the signaling files. Further, timing information included in the recovery file is used to synchronize the supplementary content with the uncompressed data from the external input source.

Client identifier watermarks in media signals are disclosed. An example apparatus to watermark a multilayered file includes a watermark storage to store media identifiers. The example apparatus also includes an encoder to encode a first bit sequence in the media file on a first encoding layer of a multilayered watermark, the first bit sequence to include a client identifier of a client associated with the media file, and encode a second bit sequence in the media file on a second encoding layer of the multilayered watermark, the second bit sequence to include a media identifier to identify media corresponding to the media file.

Methods, apparatus, systems and articles of manufacture to extend a time range supported by a watermark are disclosed. Example watermark encoding apparatus disclosed herein determine which one of a plurality of timestamp cycles is to be represented by a timestamp of a watermark. Disclosed example apparatus also swap at least two symbols of the watermark when the timestamp is to represent a second one of the timestamp cycles, but do not swap the at least two symbols of the watermark when the timestamp is to represent a first one of the timestamp cycles. Disclosed example apparatus further embed the watermark in a first piece of media.

A media presentation and distribution system communicatively coupled to a client device is provided. The client device receives a media stream from the media presentation and distribution system via a network. The media stream includes media content and one or more tags. The client device further identifies in the received media content, the one or more tags, which corresponds to the overlay-graphic items. The client device further identifies candidate time-periods in the media content based on the one or more tags in the media content. At least one presentation attribute for the overlay-graphic items is identified based on the one or more tags in the media content. The client device further presents the overlay-graphic items at the candidate time-periods on the media content based on a degree of correlation between the identified tag in the media content and a corresponding context for the media content at the candidate time-period.

Methods and apparatus to perform audio watermarking and watermark detection and extraction are disclosed. Example apparatus disclosed herein are to select frequency components to be used to represent a code, different sets of frequency components to represent respectively different information, respective ones of the frequency components in the sets of frequency components located in respective code bands, there being multiple code bands and spacing between adjacent code bands being equal to or less than the spacing between adjacent frequency components in the code bands. Disclosed example apparatus are also to synthesize the frequency components to be used to represent the code, combine the synthesized frequency components with an audio block of an audio signal, and output the audio signal and a video signal associated with the audio signal.

An example apparatus includes at least one processor circuitry to execute or instantiate instructions to identify a media file is scheduled to be accessed by a media device within a first time period after a publishing of the media file was published by a media provider; select a first symbol to be inserted at a first symbol position and a second symbol to be inserted at a second symbol position to identify an access of the media file is to be accessed by the media device within the first time period, the first symbol position in a first bit sequence, the second symbol position in a second bit sequence; encode the first bit sequence in the media file on a first encoding layer of a multilayered watermark, and encode the second bit sequence in the media file on a second encoding layer of the multilayered watermark.

Techniques are described for integrated sharing of media playback interactions (MPIs). Responsive to consumer interactions with media content during playback of a media file, embodiments can produce MPIs corresponding to the consumer's changes in the playback presentation of the content. The MPIs can be associated with the media file as one or more sharable embedded MPIs (EMPIs). A consumer can share the media file with its associated EMPIs. When the same or a different consumer subsequently accesses the content from the media file, embodiments permit playback of the content with selective access to the EMPIs. For example, a first consumer can share media content with its associated EMPIs, thereby permitting a second consumer control over which portions of the media content are played back with and without experiencing the first consumer's EMPIs.

Methods and system for providing content based on an embedded signal are disclosed. A method can comprise generating a placement signal based on an event, repeatedly embedding the placement signal into a data stream, and transmitting the data stream comprising the repeatedly embedded placement signal.

A media presentation device determines a voice command associated with media content presented by the media presentation device. The media presentation device then listens for and detects utterance of the determined voice command during presentation of the media content, and the media presentation device responds to the detected utterance by performing an action that facilitates user purchase of the good or service associated with the media content segment.

A method and system for using steganographically-encoded time information as a basis to control when a client carries out a content-related action. The client processes for presentation one or more linear media streams, each defining a respective time sequence of frames of media content, and at least one of the streams being steganographically encoded with at least one watermark at a respective time-point within the linear media stream, the watermark encoding a timestamp of the respective time-point within the linear media stream according to a server clock. The client extracts the timestamp from the watermark and computes a time offset based on a difference between the extracted timestamp and a current time according to a client clock. And the client uses the computed time offset as a basis to determine when the client should carry out a content-related action in a given one of the one or more linear media streams.
