  • Patent number: 7119675
    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.

  • Publication number: 20060218226
    Abstract: An intelligent agent has a local component associated with a user device and a network component capable of mobility that will traverse different locations on a network to discover available media content that meets the user's stored preferences. Using published presence information or user schedule information, the intelligent agent will locate a user device accessible to the user and provide notification when media content of interest is discovered. The intelligent agent mediates the media acquisition and delivery process. Content can be delivered to any one or more diverse user devices, based on user instructions or preferences. The intelligent agent interacts with authentication and purchasing mechanisms to effect secure transactions on the user's behalf.

  • Patent number: 7058964
    Abstract: A digital cable network architecture and services method includes a cable medium and a plurality of hosts that include a receiver. A policy file store contains policy files having at least one of a service provider section, a consumer section, and a manufacturer section that can be updated by at least one of the service provider, a consumer and a receiver manufacturer, respectively. A service provider that is associated with the policy file store provides digital cable services over the cable medium to the hosts and downloads monitor applications and policy files to the hosts over the cable medium. The MAs use the service provider section, the consumer section, and/or the manufacturer section of the policy file to alter resource contention, alter service provisioning at levels below a channel level, and/or alter fraudulent receiver identification calculations.

  • Patent number: 6993132
    Abstract: A digital cable network architecture includes hosts that include a receiver with a hash function generator that calculates hash values based on a hash function and data from memory blocks in the receiver. A policy file store contains policy files having a service provider section, a consumer section, and/or a manufacturer section that can be updated by the service provider, a consumer and/or a receiver manufacturer. A service provider downloads monitor applications (MAs) and policy files to the hosts over the cable medium. The MAs access the service provider section, the consumer section, and/or the manufacturer section of the policy file to alter resource contention, service provisioning, and/or alter fraudulent receiver identification calculations. The hash function of the receiver outputs the hash values to the MA, which compares the hash values to expected hash values to identify fraudulent access.

  • Patent number: 6952576
    Abstract: An entertainment device is provided for adaptively tuning to a content signal. The entertainment device includes a receiver responsive to content signals provided to the entertainment device. A selected channel of the receiver provides an output signal to an output terminal of the automobile entertainment device. A data processor is operably linked to the receiver for receiving a signal index of the content signal. The data processor is responsive to a predetermined signal index for actuating the receiver to select the specific channel corresponding to the predetermined signal index. A memory stores the predetermined signal index in accordance with an operator preference. Thus, the predetermined signal index enables the entertainment device to adaptively adjust to an operator's preferred content.

  • Patent number: 6490513
    Abstract: A vehicle data archive system is provided. An instrumentation interface receives at least one sensory data signal of the vehicle. A memory stores the at least one sensory data signal. A first transponder responds to a periodic provider signal of a trusted third party (TTP)/service provider for creating a corresponding shared encryption key, which is used to generate a digital signature from the stored data, the signature may be stored with the data or returned to the TTP/service provider. The signature is used to authenticate the data stored in the archive system. The encryption value used to generate the signature may be stored locally in the data archive or obtained from the TTP/service provider. The data in the data archive may also be stored without encryption. The system also allows an authorized user to delete a portion of the stored encrypted sensory data.
