Systems and methods for binding content to pairing of a playback device and removable memory storage device are disclosed. In one embodiment, a method for requesting authorization to play content using a playback device and a removable memory storage device includes retrieving a coupon identifier from a removable memory storage device while it is attached to the playback device, generating a coupon code using the coupon identifier, sending a request for storefront token that includes a device match data token and an application identifier, receiving a storefront token associated with a storefront identifier where the storefront identifier identifies a storefront application, sending a request for ticket token that includes the coupon code, the storefront identifier, and a content identifier that identifies the content, sending a request for license file that includes the ticket token, and receiving a license file that grants playback rights to the piece of content.

Embodiments of this application provide a digital rights management DRM method, apparatus, and system, to implement a DRM interworking operation between DRM servers and clients of different vendors. The method includes: A DRM server encrypts a first media file by using a first encryption method to obtain a first encrypted media file; the DRM server generates content protection description information of the first encrypted media file, where the content protection description information includes a content identifier and encryption method information, the content identifier identifies the first encrypted media file, and the encryption method information identifies the first encryption method; the DRM server performs first formatting on the content protection description information to generate formatted content protection data; the DRM server encapsulates the formatted content protection data to generate a content protection data packet.

System and computer-implemented method for license management of virtual appliances in a computing system uses an activated virtual appliance in the computing system to forward an activation license from a license server on behalf of an unactivated virtual appliance in the computing system.

There is provided a method of permitting one or more features on a computer program. The computer program executing on a hardware with a hardware identifier. The method comprises, at the authentication server, receiving an authentication key indicating authorised features of the computer program, generating a server key based on the hardware identifier and a feature list, and comparing the authentication key with the server key. The method further comprises, at the authentication client, receiving a feature request comprising one or more features to be permitted on the computer program, generating a feature verification message based on the one or more features, and transmitting the feature verification message to the authentication server. The method further comprises, at the authentication server, receiving the feature verification message, verifying that the one or more features are within the feature list, generating a response key if the one more or more features are within the feature list and the authentication key matches the server key, and transmitting the response key to the authentication client. The method further comprises, at the authentication client, receiving the response key, and permitting the one or more features on the computer program.

A method is provided that determines whether to allow an application (app) for use or restrict the app on a set top box (STB). The method includes the steps of measuring at the STB, one or more resources used by the app; comparing at the STB, one or more thresholds set by an operator; and determining if the one or more resources used by the app exceed one or more thresholds set by the operator. Another method is provided that monitors applications (apps) that are installed a set top box (STB) for illegal or harmful activity by a policy manager. This method includes downloading and copying an app from an external source; installing or uninstalling the app into an application folder; providing a notification informing the policy manager of the installing or uninstalling of the app; and evaluating the app be installed or uninstalled.

Systems, methods, and storage media for authenticating a remote viewing device for rendering digital content are disclosed. Exemplary implementations may: transmit an initial display to be displayed on the viewing device; receive a request, from the viewing device, to view content; transmit an indication of the request to a mobile device associated with a user who is authorized to view the content; receive, from the mobile device, approval of the viewing device for viewing the content; and authenticate the viewing device for viewing the content in response to the approval of viewing device whereby the content can be viewed on the viewing device.

A map output device is provided for preventing a storage medium from being sharedly used. The map output device comprises a connection unit; an output unit that outputs map data; and a control unit. The control unit is configured, when a storage medium is connected to the connection unit or when a movable body is used beyond a predetermined usage amount, to write a file containing information on a unique value related to the movable body into the storage medium connected to the connection unit, and to output, to the output unit, the map data read from the storage medium.

A multi-device digital rights management server is provided. The server may include, but is not limited to, a processor communicatively coupled to a communications system and a memory, the processor configured to receive, from the communications system, a request to transfer digital content from a first user device to a second user device, update, upon receipt of the request, digital rights management data stored in the memory to enable both the first user device and the second user device to consume the digital content, receive, from the communications system, notice that one of the first user device and the second user device is consuming the digital content, update, upon receipt of the notice, the digital rights management data to disable the other of the first user device and the second user device from consuming the digital content.

A method for content delivery to a user device, that helps to reduce bandwidth requirements and increases security of the content. The method includes receiving a download request from the user device, the download request including request data corresponding to characteristics of the user device, analyzing the request data to select a bootstrap module; transmitting the bootstrap module to the user device for download; analyzing an authentication characteristic to determine that the user device is authenticated for content viewing; transmitting a content catalogue to the user device; and upon receiving a user selection of a content item from the content catalogue, transmitting the user selected content item to the user device.

A video is provided to viewers using a web-based platform without restricted audio, such as a copyrighted soundtrack. To do so, a video comprising at least two audio layers is received. The audio layers can include separate and distinct audio layers or a mix of audio from separate sources. A restricted audio element is identified in a first audio layer and a speech element is identified in a second audio layer. A stitched text string can be generated by performing speech-to-text on both audio layers and removing the text corresponding to the restricted audio element of the second audio layer. When playing back the video, a portion of the video is muted based on the restricted audio element. A voice synthesizer is employed to generate audible sound during the muted portion using the stitched text string.
