9,129,089, "Digital rights management with persistently-unencrypted content," assigned to Microsoft.
A digital rights management license provides access to a decryption key that can be used to decrypt an encrypted digital content item. The digital rights management license also includes a policy that defines circumstances in which the decryption key is allowed to decrypt encrypted content data for the purpose of creating a persistently-unencrypted version of the content data.
9,129,093, "Systems and methods providing a separable digital rights management application, " assigned to Cox Communications.
Systems and methods providing content having digital rights management (DRM) applications separable from other authorization applications are provided. A system may include a distribution service provider system in communication with a content provider system and consumer premise equipment (CPE) for the transmission of content from the content provider system to the CPE device. The distribution service provider system may: receive A/V content provided by the content provider system, wherein the A/V content includes a DRM application; apply a conditional access system (CAS) application to the A/V content that is independent of the DRM application; and transmit the A/V content including the CAS and the DRM applications to the CPE for presentation. The CPE device can perform DRM authorizations with the content provider or a third-party DRM provider.
