  • Patent number: 11886545
    Abstract: Federated systems for issuing playback certifications granting access to technically protected content are described. One embodiment of the system includes a registration server connected to a network, a content server connected to the network and to a trusted system, a first device including a non-volatile memory that is connected to the network and a second device including a non-volatile memory that is connected to the network. In addition, the registration server is configured to provide the first device with a first set of activation information in a first format, the first device is configured to store the first set of activation information in non-volatile memory, the registration server is configured to provide the second device with a second set of activation information in a second format, and the second device is configured to store the second set of activation information in non-volatile memory.

  • Publication number: 20230396820
    Abstract: Systems and methods for performing adaptive bitrate streaming using alternative streams of protected content in accordance with embodiments of the invention are described. One embodiment of the invention includes a processor, and memory containing a client application. In addition, the client application configures the processor to: request a top level index file identifying a plurality of alternative streams of protected content, where each of the alternative streams of protected content are encrypted using common cryptographic information; obtain the common cryptographic information; request portions of content from at least the plurality of alternative streams of protected content; access the protected content using the common cryptographic information; and playback the content.

  • Patent number: 11468149
    Abstract: Content screening operations, which can include watermark extraction and the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted by different devices that are connected via connectors such as HDMI (High-Definition Multimedia Interface (HDMI), analog composite video, DVI (Digital Visual Interface), SDI (Serial Digital Interface), DisplayPort, or networked via Ethernet or wireless. Authentication and encryption methods are disclosed that can be used to establish the trust and secure communication between devices that conduct collaborative content screening. Delegation architecture may be based on ascertained screening capabilities of the sink device wherein the source device verifies that the sink device is capable and trusted to perform partial or whole screening operations delegated by the source.
