On Tuesdays the USPTO issues new patents. Both of today's Spotlight Patents concern aspects of digital rights management. Assigned to LG Electronics (KR), the first patent addresses techniques for an DRM interoperable system. Assigned to Britesmart, the second patent addresses techniques to use, share and manage digital content by assigning MAC and IP adress to each device and peripheral.
8,082,350, "DRM interoperable system," assigned to LG Electronics Inc. (KR).
A DRM interoperable system is provided. The DRM interoperable system includes: a domain manager which manages a domain; first and second devices which are authenticated by the domain manager and registered in the domain; and a control unit which gathers information on entities that are to participate in transmission of data when the first device requests the second device to transmit the data, controls at least two entities so that a chain including the at least two entities is constructed by using the gathered information on the entities, and controls the at least two entities so that a plurality of data is transmitted to the second device through the chain. Accordingly, it is possible to provide a DRM interoperable environment in which data can be effectively transmitted.
8,068,519, "Method and system to use, share and manage digital content by assigning MAC and IP adress to each device and peripheral," assigned to Britesmart LLC.
The invention shows a method for connecting and sharing content over a plurality of devices, and over a plurality of networks public and private while respecting the content's Digital Rights by implementing a software layer (software alternately integrated into hardware component) that will assign a mac address and an ip address to each device and peripherals and where content can be assign to specific devices inside a network, and can be accessed directly, shared remotely, wireless, or physically connected. The software layer also integrates drivers, players, codec's that can be updated dynamically in order to keep them updated. This software layer can also "virtualizes" peripherals, devices or group of peripherals and devices into single addressable group of components that will act like one.
