A system and method are disclosed for providing a digital medium, such as a Digital Video Disc (DVD), enabling playback of different versions of a media presentation depending on the locality of the viewer, where each version includes embedded advertisements for a corresponding locality. In one embodiment, a DVD stores a media presentation such as, for example, a movie, an episode of a television program, or the like. Depending on the location of the viewer, the DVD provides a version of the media presentation having embedded advertisements relevant to the locality of the viewer.

A system and method are disclosed for providing client-side protection of broadcast or multicast multimedia content for non-real-time playback. A set-top box function receives a request to record multimedia content and determines whether recording of the multimedia content is restricted. Upon receiving the multimedia content, the set-top box decrypts the multimedia content for real-time playback. If recording of the multimedia content is restricted, the set-top box re-encrypts the multimedia content and generates a packaged file including the re-encrypted multimedia content and one or more of a content identifier, a set-top identifier, a network reference to a copyright policy server, and a record policy of the multimedia content. The packaged file is either stored locally or transferred to remote storage. A remote system having access to the packaged file obtains the packaged file and enforces a copyright policy of the multimedia content before releasing the multimedia content for non-real-time playback.

A digital content review and distribution system and method are provided. In general, a number of authors of digital content register with a content review and distribution agent, which may be hosted by a central server. The authors agree to review digital content submitted by other authors in exchange for review and distribution of their own content. In operation, an author submits metadata associated with digital content to be reviewed and optionally the digital content to the content review and distribution agent. In response to the submission, the content review and distribution agent effects a review of the digital content by one or more groups of reviewers, where the groups of reviewers are selected from the other authors registered with the content review and distribution agent based on the metadata for the digital content and reviewer credentials of the other authors.

A system and method are provided for controlling content played by a number of media devices. In general, the system includes a mobile device and the number of media devices. The mobile device includes a wireless communication interface for communicating with the media devices, a media database, and a control system including a media client. When the mobile device enters a Wireless Personal Area Network (WPAN) associated with a media device, the media client obtains information describing the content residing at the media device and stores the information in the media database at the mobile device. Thereafter, when the mobile device is within the WPAN associated with the media device, the media database is used to select content to be played at the media device.

A system and method are provided for synchronizing playback of media content on multiple playback devices utilizing Digital Rights Management (DRM) encoding. In general, multiple playback devices or users of those playback devices are associated to form a virtual group. A virtual group (VG) control function operates to synchronize advertisement (ad) slots within media content provided to the playback devices in the virtual group utilizing DRM encoding.

A system and method for transferring Very Large Files (VLFs) from a content provider to a requesting node over a network via a proxy are provided. The content provider processes a VLF to provide a chunked VLF. The chunked VLF includes a number of chunks each including a portion of the VLF. A transfer is initiated when a request for the VLF is sent from the requesting node to the proxy. The proxy then determines if any of the chunks of the chunked VLF are stored in proxy cache associated with the proxy. If not, the proxy directs the request to the content provider. In response, the content provider sends the chunks of the chunked VLF to the proxy. Upon receiving each of the chunks, the proxy stores the chunk in the proxy cache and sends the chunk to the requesting node.

摘要:
The present invention provides a system and method for recommending operational information, such as play lists or settings, for one or more devices associated with a local wireless network based on content information describing content stored on a number of user devices within the local wireless network. More specifically, a recommendation engine obtains the content information for a number of user devices within the local wireless network from either a central node or the user devices and analyzes the content information to recommend operational information for one or more devices associated with the local wireless network.

A social network circuit includes two or more members of a social network in live communication with one another. Systems and methods of administering social network circuits include computing devices configured to determine the existence and extent of social network circuits. Client applications associated with computing devices used by each member may be configured to provide one or more servers with session data indicating the existence of live communication links. Based on the session data, the server(s) may track one or more social network circuits. Data representing the circuits may be provided to the clients in the circuits. Clients may selectively participate in social network circuits based on user- and system-provided parameters. For example, a subset of social network users in active communication may be further divided into a particular social network circuit devoted to a particular topic of discussion. Users may participate in multiple social network circuits at any given time.

A system and method for client-side watermarking of digital content using hybrid Intra-Frames (I-Frames) are provided. In general, a content source provides a compressed video stream and a hybrid I-Frame stream to a client device via a network. The hybrid I-Frame stream includes a number of low-loss I-Frames corresponding to select ones of the I-Frames in the compressed video stream to be used for client-side watermarking. The client device watermarks the I-Frames in the hybrid I-Frame stream, optionally compresses the watermarked I-Frames, and replaces the select ones of the I-Frames in the compressed video stream with the watermarked and optionally compressed I-Frames to provide a watermarked version of the compressed video stream.
