On Tuesdays, the USPTO issues new patents. Both of today's Spotlight Patents deal with aspects of DRM. Assigned to Intel, the first patent addresses operating system independent data management. Assigned to Samsung, the second patent addresses techniques for controlling output to an output device according to each content.
7,565,685, "Operating system independent data management," assigned to Intel.
Apparatuses and methods provide operating system independent digital rights management. A request can be made for data, which can be monitored by a security module. The security module is independent of a host operating system and manages digital rights for the requested data. Thus, digital rights management occurs outside the context of a host operating system. The security module may classify the data and determine a security policy based on the data classification. Policy may be stored locally or remotely, and may be associated with the data subject to the policy.
7,565,530, "Source device and method for controlling output to sink device according to each content," assigned to Samsung (KR).
A source device and a method are provided for certifying and controlling A/V signals output from an A/V device through an output terminal of a digital visual interface (DVI) or a high definition multimedia interface (HDMI), using Digital Rights Management (DRM). The source device includes: a DRM module which decrypts encrypted multimedia contents included in DRM contents through certification of a source device, and generates a control message for controlling digital A/V channels connected between the source device and a sink device based on a DRM rule; an input controller which certifies A/V data input from a media decrypter, and outputs A/V data filtered according to a certifying result; an input interface which converts the filtered A/V data into pixel data and audio data; and a signal transmitter which encrypts and converts the pixel and audio data into high-speed serial digital A/V signals to be transmitted to the sink device.
