11665170 · 2023-05-30 · ·

Systems and methods for providing access to media content by connecting, to a public device, a private device that has an installed application associated with the media content. A media guidance application may receive a communication from a private device, running a private interface application, requesting to access content using the public device. In response, the media guidance application may retrieve, at the public device, a public interface application associated with the private interface application, from a content provider of the content. The private interface application may be configured to control a graphical user interface of the public interface application. Accordingly, the user may be able to access content via the public device when the private device is within a predetermined proximity to the public device.

Pairing method between a multimedia unit and at least one operator, multimedia unit, operator and personalization entity for the implementation of this method

The present invention relates in particular to a pairing method between a multimedia unit and one operator having an operator identifier, the multimedia unit having a multimedia unit identifier and receiving conditional access data from said operator, the method being characterized in that: receiving by the multimedia unit a multimedia unit key formed by applying a first cryptographically function to a personalization key and to the multimedia unit identifier; receiving by the operator an operator key formed by applying a second cryptographically function to said personalization key and to the operator identifier; said multimedia unit further having a function of the multimedia unit and said operator further having a function of the operator, these functions being such that the result of the application of the function of the operator to said operator key and to said multimedia unit identifier is equal to the result of the application of the function of the multimedia unit to said multimedia unit key and to said operator identifier, this result forming a pairing key between said multimedia unit and said operator.

11627119 · 2023-04-11 · ·

The present invention provides methods, apparatuses, and systems for delivering protected streaming content to a receiving device. In an aspect of the present invention, a broadcaster provides streaming content. To ensure viewers are properly authorized, the streaming content is encrypted with a traffic key. The traffic key is provided to the users via a key stream message, which is encrypted with a service key. The user obtains at least one rights object from a rights issuers and the at least one rights object includes the service key so that the streaming content may be used. The at least one rights object also contains information regarding usage rights that may be configured by the rights issuer so that, depending on the user and/or the receiving device, different rights may be available. The key stream message may include a program category variable value that indicates the type of content and in conjunction with the rights object, determines what usage rights exist for the streaming content.

Aspects of the subject disclosure may include, for example, a user device that attaches to a radio access network of a mobile network and requests services. The user device creates a virtual network function on the device to support the service. The virtual network function may include a user plane virtual network function, a control plane virtual network function, or both. Other embodiments are disclosed.

Secure Content Distribution and Trusted Recording of Content Consumption

Techniques for a trusted system for secure content distribution and trusted recording of content consumption are described. In some embodiments, the trusted system transcodes and transcrypts a media content item using a key obtained from a content provider and one or more keys based on an entitlement from a service provider to generate an encrypted media content item. The trusted system further receives a request to provide the media content item to a client device. The trusted system also obtains a signed audit token recording the request upon an authorization by the service provider based on the entitlement and a confirmation by the content provider, where the signed audit token is signed by the content provider and the service provider. The trusted system additionally provides the one or more keys for decrypting the encrypted media content item and reports the signed audit token.

FAST-EXPIRING LICENSES USED TO SPECULATIVELY AUTHORIZE ACCESS TO STREAMING MEDIA CONTENT
20230205852 · 2023-06-29 ·

Techniques are disclosed for improving user experience of multimedia streaming over computer networks. More specifically, techniques presented herein reduce (or eliminate) latency in playback start time for streaming digital media content resulting from digital rights management (DRM) authorizations. A streaming media client (e.g., a browser, set-top box, mobile telephone or tablet “app”) may request a “fast-expiring” license for titles the streaming media client predicts a user is likely to begin streaming. A fast-expiring license is a DRM license (and associated decryption key) which is valid for only a very limited time after being used for playback. During the validity period of such a license, the client device requests a “normal” or “regular” license to continue accessing the title after the fast-expiring license expires.

INTEGRATION OF PLATFORMS FOR MULTI-PLATFORM CONTENT ACCESS
20230209116 · 2023-06-29 ·

Techniques described herein are directed to integration of platforms for multi-platform content access. In an example, a user may request access to access-restricted content. A payment application on the user device that requested access may communicate with an associated payment service to automatically pay for the access without requiring additional user input, or may request the user to confirm that the payment is desired. This may be performed across content provider platforms and in a way that allows subsequent access to the content regardless of the platform used to request the content.
