Publication number: 20170164046Abstract: 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.Type: ApplicationFiled: December 12, 2016Publication date: June 8, 2017Inventors: Talal G. SHAMOON, Ralph D. HILL, Chris D. RADCLIFFE, John P. HWA, W. Olin SIBERT, David M. VAN WIE

Patent number: 7233948Abstract: 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.Type: GrantFiled: March 25, 1999Date of Patent: June 19, 2007Assignee: Intertrust Technologies Corp.Inventors: Talal G.

Publication number: 20020095613Abstract: A method and apparatus for synchronizing asynchronous time-based and motion data in a system in which the time-based data and motion data are transmitted by a server over a network to a client including retrieving a time-based data stream and a motion data stream at the server. Each stream comprising frames of data. One of the time-based data stream and the motion stream is variably buffered to produce two streams having synchronized frames. The synchronized frames are used at the client for playback of synchronized motion and time-based data to a user.Type: ApplicationFiled: February 6, 2002Publication date: July 18, 2002Inventors: Shinya Matsuoka, John P.
