The present invention relates to steganographic encoding for multimedia content. In one combination, a method is provided including: encoding first information in a first component of a multimedia signal, the first component comprising audio, the first information being encoded though subtle changes to data representing the first component; encoding second information in a second component of the multimedia signal, the second component comprising video, the first information being encoded though subtle changes to data representing the first component, the first information and the second information are associated. Of course, other combinations are provided as well.

Methods are disclosed for associating content objects (e.g., paper documents, audio and video files, etc.) with corresponding information and/or action. One arrangement employs an architecture comprising a registration server, a router, and one or more product handlers. Identifiers for the content objects can be obtained in various ways, including decoding a digital watermark, deriving an identifier by hashing music data, sensing machine-readable data such as RFID or barcode data, etc. The technology is suitable for use with handheld devices, including cell phones and media players.
摘要:
A method of performing digital asset management of media content. In this method, a watermark reader device reads a watermark embedded into media content. The watermark conveys watermark information, such as a content identifier and creator identifier. The reader forwards the watermark information to a router. The router then uses the watermark information to find a metadata database identifier. It then sends a request for metadata along with the watermark information to the metadata database identified by the metadata database identifier. The metadata database uses the watermark information to find related metadata for the media content and sends the related metadata to the reader device.

This invention deals with improving recommendation systems. The first embodiment combines rules and recommendations to create automated and intelligent business rules for recommendations. The second embodiment improves recommendations by combining the results of driver products and influencer products, where influencer products only influence the recommendations of the driver products. Influencer products can be related to a specific user. The third embodiment improves recommendations for new items by relating them to original items, such that the sales for the original item is used in the new item when calculating recommendations. The new items may replace the original item, or be a similar item and exist alongside the original item.

The disclosure relates generally to methods and systems including, e.g.,: (1) steganographically embedding location information in image or audio content, where the location information is obtained from remote sources like a cell phone network or remote GPS receiver; (2) steganographically embedding participant IDs in content to ensure proper billing and royalty tracking; (3) providing fair-use content management based upon digital watermark-tracked usage; (4) providing micro-payments based upon watermarked objects for retailers; and/or (5) providing watermarked logon cards, such as watermarked hotel room keys, to better provide internet logon access control. Other systems and methods are provided as well.
摘要:
The present application relates generally to content management (e.g., managing audio and video items in portable devices). One claim recites a method comprising: utilizing electronic memory housed in a portable device, maintaining a listing of up to N identifiers associated with previously accessed audio or video items, where N is an integer, and where each previously accessed audio or video item has an identifier associated therewith; utilizing a programmed electronic processor housed in the portable device, i) restricting access to a new audio or video item if an identifier associated with the new audio or video item is one of the N identifiers associated with the previously accessed audio or video items, or ii) limiting a number of content items each with a different user identifier associated therewith that can be accessed in a certain amount of time. Of course, other claims and combinations are provided as well.
摘要:
The present invention describes methods and apparatus involving embedding data. Data can be embedded steganographically in content or embedded in, e.g., headers associated with the content. In one implementation, a method of embedding auxiliary information in data is provided. The method includes receiving data and correlated data. The correlated data is related to but independent from the received data. The method further includes receiving auxiliary information, the auxiliary information being independent of the received data and the correlated data; changing the auxiliary information based on at least the correlated data; and embedding the changed auxiliary information in the received data. Other implementations are also provided.
摘要:
A method for controlling watermark embedding in a media object through the use of a watermark embedding command. The use of the embedding command enables watermark embedding to be adapted for the transmission channel at the time of transmission.

Digital watermarking provides a chain of custody for video in movie studios. Several novel improvements in workflow processes for digital watermarking provide chains of custody. In a first implementation, a digital watermark payload includes an embedder ID and time stamp. The embedder ID is associated with a controlling PC user log, including, e.g., the user log being linked to a biometric of the user. In a second implementation, a video player is forced to run a video digital watermark embedder based upon a rights command, where an ID embedded in a watermark payload is determined solely by the embedder. A third implementation encrypts a conglomerate of watermarked segments of video so that a rendering device can decrypt the segments in a manner to produce different results in each usage dependent upon the key. A fourth implementation embeds digital watermarks in DVD disk images during delivery to a duplication house.
摘要:
The present invention relates to deriving and/or utilizing content signatures. A content signature includes a representation of a content item, which is derived or calculated from the content item itself. One claim recites a method comprising: obtaining a content item; transforming the content item to obtain transform domain coefficients; applying Viterbi decoding to a set of the transform domain coefficients; and using a result of the Viterbi decoding as a content signature representing features or characteristics of the content item itself. Other claims and combinations are provided too.
