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.

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.

Systems and methods for binding of cryptographic content using unique device characteristics with server heuristics in accordance with embodiments of the invention are disclosed. One embodiment includes a processor and memory includes collecting a combination of device characteristics that uniquely identify the device using information stored on the device and accessible to the device using the device processor, generating device match data based upon the collected combination of device characteristics using the device processor, generating a device protection key using the device match data, encrypting the cryptographic data using the device protection key, and storing the encrypted cryptographic data in device memory using the device processor.

Binding of cryptographic content using unique device characteristics with server heuristics

Methods and systems for the remote certification testing of user video devices. In an embodiment, test logic and any related test input data is sent from a remote source such as an application server to a user video device. The test logic is executed at the user video device, and test results are output. The test results are sent back to the application server. The operation of the application server may be facilitated by a database. In embodiments, such a database stores test logic and test input data, and/or stores tests results for subsequent analysis.

Methods and systems to provide supplemental content to a user who is viewing video or other content. The user's device (through which he will access the video) then provides an identifier of that video to a server or other computing facility. Here, the video identifier is used to identify supplemental content that corresponds to the user's video. The supplemental content is then provided to the user device for the user's consumption. The supplemental content may be structured in such a way that pieces of the supplemental content are accessible at particular points in the video. The piece(s) of the supplemental content available at a particular point in the video will be related to one or more objects that are present at this point. This allows a user to access one or more pieces of supplemental content in a context-specific manner, at a point in the video where the piece(s) of supplemental content are relevant.
