On Tuesdays the USPTO issues new patents. Both of today's Spotlight Patents address various aspects of DRM. Assigned to Widevine, the first patent concerns techniques for securely providing content viewable on a secure device. Assigned to Motorola, the second patent concerns techniques for for recording and editing digital broadcast content.
A system, apparatus, and method are directed to providing and securely viewing secure content. In one embodiment, a secure player provides secure screening/previewing of secure content, such as a motion picture, by a member of an awards organization. A content key is employed to selectively encrypt at least a portion of a content stream. The content key is encrypted with a screener key. The encrypted content key is embedded into the secure content. The screener key is encrypted using public/private key pair that is bound to the secure player. The secure content may be distributed on a medium, such as a DVD, high definition DVD, and the like. The secure player is configured to receive the medium, screener key, and a screener identity. The screener identity and screener key are employed by the secure player to decrypt and enable secure viewing of the content.
7,643,564, "Method and apparatus for recording and editing digital broadcast content," assigned to Motorola.
A wireless mobile terminal (10) and method for utilizing digital broadcast content records (204) selected digital broadcast content as received, for example, by a digital broadcast receiver (16) and provides editing of the selected digital broadcast content based on digital rights management data to generate customized clips of information. The selected digital broadcast content is edited (206) to produce mobile terminal edited digital broadcast content that may be, for example, distributed (208) by the mobile terminal to a plurality of peer devices. A broadcast content editor (24) allows for the editing of clips of content wherein the edited clips are then stored in memory as recorded clips for distribution by the mobile terminal. In another embodiment, a network element is remotely controlled by the mobile terminal to effect editing through the mobile terminal at the network element.
