On Thursdays the USPTO publishes new pending patent applications. Both of today's Spotlight Applications concern aspects of digital rights management. Assigned to Comcast, the first application discloses the use of DRM in an Internet Protocol (IP) to Video-on-Demand (VOD) gateway. Assigned to Microsoft, the second application discloses techniques for issuing a publisher use license off-line in a digital rights management (DRM) system.
20100281508, "Internet Protocol (IP) to Video-on-Demand (VOD) Gateway," assigned to Comcast.
A media server is hosted in a service provider's network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance network. Media content may be stored by accessing the media server or by downloading the media content to the media server. Support of set top boxes interacting with voice-on-demand (VOD) controllers and computers interacting with IP-based video content servers are integrated through the media server. Consequently, VOD assets can be played on IP-based devices and IP-based content can be played on set top boxes. A gateway function converts IP-based content to a VOD asset, and renders the VOD asset to a set top box while mapping digital rights management information for the VOD asset. Conversely, the gateway function may convert a VOD asset to IP-based content that can be played on an IP-based device.
20100281253, "Issuing a publisher use license off-line in a digital rights management (DRM) system," assigned to Microsoft.
A publishing user publishes digital content and issues to itself a corresponding digital publisher license to allow itself to render the published digital content. The publishing user is supplied with a publishing certificate from a digital rights management (DRM) server, where the publishing certificate allows the publishing user to so publish the digital content and to so issue the publisher license.
