The ability to remove a watermark from an encoded image opens the possibility of various novel applications. Several such applications are detailed. One employs a reversible watermark in conjunction with a second (robust) watermark. In this arrangement, the payload of the reversible watermark conveys information about the robust watermark (e. g. , encoding parameters, or an error signal), permitting removal of the robust watermark from an uncorrupted encoded image. By such arrangements, the encoded image can be fully restored to its pristine, unencoded state even if several different watermarks have been applied.

Described are methods and devices for automatically coupling two or more mobile communication devices () to share content such as calls, music, documents, video and games where two or more devices automatically determine the feasibility of sharing the content and negotiate to find an efficient manner in which to do so. In this way, the pairing between devices may be transparent to the users. Moreover, a better choice in a transport may be selected without user input. Each device may include a near field communication (NFC) device that when in range of the other device may automatically initiate pairing between the devices so that the devices may share content. The users of NFC enabled devices may have little or minimal interactions except that one or more users may bring the devices within range so that the NFCs may initiate the pairing between the devices.

The disclosure describes methods for using digital watermarking to authenticate digital media signals, such as images, audio and video signals. It also describes techniques for using embedded watermarks to repair altered parts of a media signal when alteration is detected. Alteration is detected using hashes, digital watermarks, and a combination of hashes and digital watermarks.

System and methods for media distribution are described. In one embodiment, a method of media distribution includes rendering of a media to a user, stopping the rendering of the media, and storing remaining media not rendered to the user in a user server. The method further includes receiving a request to stream the remaining media to the user, dividing the remaining media into segments, and assigning a priority to each segment. The remaining media is streamed, leaving out segments with priority lower than a threshold priority.

The ability to remove a watermark from an encoded image by reversible watermarking opens the possibility of various novel applications. Several such applications are detailed. One permits different classes of consumers to gain access to different versions of an image. A pristine image is intentionally degraded in some fashion, and distributed to consumers. By reference to one or more watermarks in the degraded image, some or all of the degradation can be removed, or transformed to a less-objectionable state. Through such arrangements, image consumers with different needs can gain access to versions of the image having differing qualities.

A method and apparatus are described for determining a threshold, including selecting a desired false result probability, and selecting a threshold value from a threshold table corresponding to the desired false result probability. Also described are a method and apparatus for determining a threshold corresponding to a desired false result probability, including calculating a false result probability, calculating a difference value between the calculated false result probability and the desired false result probability, comparing the difference value to a first predetermined value and comparing the difference value to a second predetermined value if a result of the first comparing act is positive.

Embodiments of the present invention provide a method, apparatus and system for temporal synchronization of digital content based on a marker symbol and a marker code. A marker symbol is inserted at an identifiable location of a payload (e. g. , the beginning and/or end of a payload) at regular intervals in the digital content and the payload is marker coded to form a periodic sequence. The payload is marker coded such that the maker symbol is not repeated by the coded payload. The periodic sequence is then embedded into digital content. A decoder is able to re-synchronize the payload by determining the location of the marker symbol. As such, a method, apparatus and system is provided for robust temporal synchronization for, for example, content encoding and decoding for applications such as audio and video water-marking and the like.
