On Tuesdays the USPTO issues new patents. Both of today's Spotlight Patents concern various aspects of DRM. Assigned to Cisco, the first patent concerns remote access to local content using transcryption of digital rights management schemes. Assigned to Nokia, the second patent concerns techniques for utilizing intelligent clock controller in digital rights management
7,500,269, "Remote access to local content using transcryption of digital rights management schemes," assigned to Cisco.
Abstract
Methods and devices allowing distribution of content that resides in a source device on a local area network (LAN) are described. A gateway between the LAN and a wide area network (WAN) receives from a sink device a request for an instance of content. The request is sent over the WAN. Distribution of the item of content within the LAN uses a first digital rights management (DRM) protocol that prevents the item of content from being distributed outside the LAN. For the item of content, the gateway converts from the first DRM protocol to a second DRM protocol that can be used for transmitting content over the WAN. The item of content can then be forwarded to the sink device according to the second DRM protocol.
7,500,270, "Method for utilizing intelligent clock controller in digital rights management," assigned to Nokia (FI).
Abstract
The invention relates to a method, electronic device and computer program for providing digital rights management. The electronic device comprises a first clock and an optional second clock. The electronic device may store at least one protected media object and rights associated with the media object. A time attack event is detected in the electronic device. A barring time is increased when a time attack event occurs. The barring time is decreased regularly. It is checked whether the barring time exceeds a predefined value at a request to present at least one media object. The at least one media object is presented if that is allowed by rights associated with the at least one media object and the barring time does not exceed the predefined value. The benefits of the invention are related to improved enforcement of digital rights.
