20080208752 | Content communication and purchase using a computer-based media component - Content communication and purchases using a computer-based media component are described. A tuner component can individually interact with client components, where each communication of content may be varied or configured independent of interactions with other client components. Additionally, content can be purchased using the computer-based media component, where the purchase and/or presentation of the content may utilize the computer-based media component and/or coupled client components. | 08-28-2008 |
20080209469 | Extensible encoding for interactive user experience elements - Detailed herein is a technology which, among other things, allows for storage and playback of interactive user elements in a television stream. In one approach to this technology, a content data stream, including a television program and a user experience element, is received. This content data stream is transformed, and the transformed data stream is examined, to identify which packets are associated with the user experience element. Those packets are then passed to a handler appropriate for the user experience element. | 08-28-2008 |
20080222044 | Protected content renewal - Described herein is technology for, among other things, maintaining access to DRM protected content. The technology may be implemented via a playback device or a computer system connected to a MTD. It involves monitoring requests for media content and then verifying access and renewing the license if necessary. The license renewal request may be made to a MTD or an internet connected system. | 09-11-2008 |
20130024905 | EXTENSIBLE ENCODING FOR INTERACTIVE EXPERIENCE ELEMENTS - Detailed herein is a technology which, among other things, allows for storage and playback of interactive user elements in a television stream. In one approach to this technology, a content data stream, including a television program and a user experience element, is received. This content data stream is transformed, and the transformed data stream is examined, to identify which packets are associated with the user experience element. Those packets are then passed to a handler appropriate for the user experience element. | 01-24-2013 |

20090192943 | Renewing an Expired License - This document describes tools capable of renewing an expired license to entertainment content. The tools, in some embodiments, may repeatedly renew a license using very little resources, such as by forgoing retention of the license, encryption keys, or the entertainment content between renewals. The tools, for example, may provide a license to a particular content receiver (e.g., a laptop computer), and, when that license expires, renew the license with as little as a single retained secret. By so doing the tools enable, among other things, fewer computing resources to be used in renewing a license while maintaining the security of that license's entertainment content. | 07-30-2009 |
20090307780 | USING TRUSTED THIRD PARTIES TO PERFORM DRM OPERATIONS - Various embodiments utilize a third party, such as a trusted third-party, to perform DRM operations such as “move” operations. In at least some embodiments, the trusted third-party is utilized for both “move” operations as well as local content access such as playback and the like. In at least some embodiments, a third-party maintains a database that includes an association of clients, content, and move version numbers. A client—termed a “source client” maintains at least a move version number locally in a secure fashion. The version number is incremented each time the source client performs a move operation. Both the source client and the third-party increment the version number each time a piece of content is moved. When the client attempts to perform a move operation, it contacts the third-party to ascertain the third-party's move version number. If the move version numbers match and the source client owns the license/content, then, in at least some embodiments, a move operation is permitted. | 12-10-2009 |
20100212016 | CONTENT PROTECTION INTEROPERRABILITY - Various embodiments provide content protection interoperability techniques which support secure distribution of content for multiple content protection technologies. In one or more embodiments a source digital rights management (DRM) system can associate trust data with content to be exported to a target digital rights management (DRM) system. The trust data describes a trust state for the content to enable the target DRM system to maintain the trust state for the exported content. In at least some embodiments, the source DRM system can also associate tracing data with the content to, in the event of a breach in the chain of trust, enable an identification to be made of a source of the exported content and/or a party responsible for exporting the content. | 08-19-2010 |
