  • Publication number: 20170164046
    Abstract: A novel method and apparatus for protection of streamed media content is disclosed. In one aspect, the apparatus includes control means for governance of content streams or content objects, decryption means for decrypting content streams or content objects under control of the control means, and feedback means for tracking actual use of content streams or content objects. The control means may operate in accordance with rules received as part of the streamed content, or through a side-band channel. The rules may specify allowed uses of the content, including whether or not the content can be copied or transferred, and whether and under what circumstances received content may be “checked out” of one device and used in a second device. The rules may also include or specify budgets, and a requirement that audit information be collected and/or transmitted to an external server. In a different aspect, the apparatus may include a media player designed to call plugins to assist in rendering content.

  • Patent number: 7233948
    Abstract: Systems and methods for protection of streamed media content are disclosed. In one aspect, the system includes control means for governing content streams or objects, decryption means for decrypting content streams or objects, and feedback means for tracking use of content streams or objects. The control means may operate in accordance with rules received in the streamed content or through a side-band channel. The rules may specify allowed uses of the content, including whether the content can be copied or transferred, and whether content may be “checked out” of one device and used in another. The rules may also include budgets, and a requirement that audit information be collected and/or transmitted to server. In another aspect, a media player is disclosed that uses plugins to assist in rendering content. A “trust plugin” is used to enable a media player designed to render unprotected content to render protected content.

  • Patent number: 6005600
    Abstract: The present invention is directed to a system and method for enabling a user to view a moving picture with synchronized audio using a workstation connected to a digital network. The user may change both speed and direction, as well as jump between arbitrary points in the movie being played. According to the present invention, digitized movie data may be accessed from different sources (e.g., network servers, local disks). These sources vary in speed and response time as a result of their capabilities (e.g., limited I/O bandwidth) and transient events (e.g., resource contention). The present invention adapts to these varying conditions in order to maintain a stable output.

  • Patent number: 5594911
    Abstract: A system and method for preprocessing and delivering multimedia presentations to customers such that delays due to interactive response time is virtually eliminated include a preprocessor, mass storage, a delivery processor, a distribution network, and a plurality of presentation processors. The preprocessor receives as inputs an original multimedia presentation and parameters characterizing other system components, which parameters include the round trip latency between the delivery processor and a presentation processor, and generates a preprocessed multimedia presentation including a delivery schedule in the form of a labelled, directed graph.
