    摘要: A communication session management method for providing a transmission service having a plurality of service-levels, each service-level being associated with a separate quality-of-service (QOS), the method including preparing data for transmission at one of the plurality of service-levels by uniquely associating a service-level encryption key with the one of the plurality of service-levels, encrypting the data with the service-level encryption key to form encrypted data uniquely associated with the one of the plurality of service-levels, and transmitting the encrypted data uniquely associated with the one of the plurality of service-levels to users entitled to the one of the plurality of service-levels.

    摘要: A system and method for providing content to users including a multicast sub-system providing content to multiple users and a unicast sub-system providing content to individual users. The multicast sub-system being operative to push to each of a plurality of user communities, content relating to the community and the unicast sub-system being operative to provide on demand to a user, content which has not been previously pushed to the user.

    摘要: A system and a method for flexible, yet secure distribution of digital content items, optionally with an automatic payment mechanism for purchasing such content. The present invention supports the distribution of content to end user devices from a central distribution point, as in client-server models and variations thereof, and/or peer-to-peer distribution, for example between end user devices. In addition, the present invention also supports distribution models within either of these mechanisms for unitary distribution, to a specified end user device, or broadcast/multicast distribution, to a plurality of end user devices. In any case, in order for the distributed content to be operative, for example to be “played back” or otherwise displayed, the recipient end user device must be in communication with a network control center. The network control center then enables the recipient end user device to play back or otherwise display the received content, for example by sending a code to the recipient end user device. Optionally, the network control center may require payment to be received before enabling the content for the recipient end user device. Thus, the present invention supports flexible distribution of content according to a number of different distribution models, while still preventing unauthorized play back or other display throughout the lifecycle of the digital content item, and optionally enabling assured payments.
