Abstract: A computer-implemented method is presented that allows a user to receive a work such as a movie at any time and at any location. A first client connects to a server through a network. A work is selected through the first client. Transaction data related to a user's right to receive a work is created and stored. A request is sent to the server to transmit the work. The work is transmitted to either the first or the second clients at any time based upon the user's right to receive the work.

Abstract: The middleware service interacts with data carousel data objects and acts as a bridge between the data carousel and subscribed control points. The middleware service can serve a variety of objects, including streams, applications, stream events and also enables new applications and services to be deployed on home networks. It connects devices without broadcast channel connectivity to broadcast channel-resident data services.

Abstract: A method for deterring or detecting the unauthorized dissemination or copying of a work is presented. Personal identification data is embedded into a work before the work is sent over a communication link to a receiver. The work is sent over the communication link to the receiver.

Abstract: A system and method for supplying media content from disparate sources includes tagging media content with an identifier tag useful in synchronization with additional media content, and useful in delivery of the media content. In other aspects, the media content is transmitted to a distribution mechanism adapted to distribute the media content to media delivery devices. In yet another aspect, the media delivery device is adapted to obtain additional media content from a disparate source, adapted to synchronize the media content with the additional media content according to the identifier tag, and adapted to deliver the media content to a consumer according to the identifier tag.

Abstract: A television entertainment system has two-way communication capability with a hand-held remote device accessing an external information source. It includes a television receiver adapted to receive television programming content, and a television set top box adapted to receive program related information over a broadcast channel and transmit the program related information to the hand-held remote device. The hand-held remote device is adapted to visually render information received over a broadcast channel and synchronize delivery of the program related information with delivery of related information from the external information source.

Abstract: A system is provided for seamless synchronization through asynchronous integration of Internet content with broadcast content within a portable handheld device (14), such as a remote control or a personal digital assistant (PDA). The handheld device (14) receives program-related data from the television (12) while the user is watching a program. The program-related data places the handheld device (14) in sync with the program the user is watching and augments the user's enjoyment of the program by providing supplemental broadcast information or additional interactive features. The handheld device (14) is also configured to retrieve additional supplemental information from at least one content source distinct from the broadcast source.

Abstract: The emergency alert service responds to receipt of emergency alert messages by filtering, formatting and routing emergency alert information to a variety of different networked appliances and also to remote devices. In this way, a consistent warning message is disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the warning task. The system thus provides a common alerting protocol that is simple but quite robust and capable of exchanging all-hazard emergency alerts and public warnings over all kinds of networks.

Abstract: A protocol for extending session endpoints in an ad-hoc network environment first performs device discovery to determine local devices within its coverage area and the capability of those devices. These local devices then exchange session descriptions with the endpoint device. If the current session may be supported by one of the local devices, the endpoint device, responsive to a command from an user, transfers the session endpoint to the local device and the endpoint device acts as a proxy for the local device in the session. Optionally, if the local device has a path to the correspondent node that is independent of the path through the endpoint device, it establishes the session along this path and then signal the endpoint node to terminate its session.
