Abstract:
The present invention allows the combination and adaptation of a broadcast data reception system with a Conditional Access System which may be embedded in the receiving device, such as a television, or can be provided as a module which is connected to the receiving device and which allows service provider controlled, typically cloud based, interactivity via the same CAS with different Multi Channel video programming distributors (MVPD) service providers.
Abstract:
Methods, devices, systems and computer program products enable generation, distribution and management of live broadcast content in such a way so as to allow identification of a pirate device or subscriber quickly and efficiently. Content is divided into content blocks, where each content block is divided into content units. Each of the content units is selectable from n variations of the content unit and a majority of ail possible combinations of content unit variations are permissible to be selected for production of the uniquely identifiable content. The content blocks, including the n variations of the content units, a media block key, and at least one device key is delivered to an authorized device. A particular pattern of content units is generated that identifies which of the n content unit variations must be used by the authorized device for constructing each content block.
Abstract:
"Variant Media Data" VMD is image data corresponding for example to n separately encrypted portions of a composite image : "key information embedded data n" (VMD-n) is image data that can be decrypted using the media key Km and a nth-segment-key Ksn. "Encrypted data of key information embedded data" in an MP4 format and encryption-metadata (vmet) storing an identifier of a decryption key of the VMD-n is acquired from a TS packet configuring the data in a MPEG-2 TS format (or from a file storing encrypted data), and stored in a box in an MP4 file, without requiring data decryption. Further, storage data of a "vloc box" specified in an MP4 format as a box storing the identifier of the decryption key of the metadata (vmet) is acquired from, or generated in, an "export" directory, to be later used to create a copied MP4 file. Technical effect : Data in the MPEG-2 TS format is converted into an MP4 file without requiring decryption / re-encryption, and the MP4 file is recorded without undermining the MPEG-2 encryption configuration for copy protection, specified now in an MP4 format.
Abstract:
Provided is a broadcast reception device connected to a conditional access module descrambling a scrambled broadcast content. The device includes: a broadcast reception unit receiving a broadcast signal; and a control unit receiving usage rule information that defines a usage of the broadcast content relating to the broadcast signal from the conditional access module and managing the broadcast content on the basis of the usage rule information.
Abstract:
Systems and methods for synchronized key derivation across multiple conditional access servers are disclosed. In one embodiment, a method for synchronized key derivation to provide playback devices with derived keys for decrypting content includes receiving a request for a first derived key that includes a first asset identifier than identifies a piece of content and a first playback position within the content, determining a first content key starting position and first derived key starting position within the content using the first playback position, where the key starting positions precede the first playback position, determining whether a first content key associated with the first asset identifier and first content key starting position is stored, retrieving the first content key using the first asset identifier and first content key starting position, generating a first derived key using the first content key and first derived key starting position, and sending the derived key.
Abstract:
A method and system for providing digital rights to a user device is set forth. The user device forms a selection signal from guide data. The user device communicates a digital rights determination signal to a first authentication module in response to selecting. The first authentication module communicates a query signal to a second authentication rnodule to determine whether the user device is authorized to receive content associated vvith the selection signal. The second authentication module communicates an address of a content delivery module to the user device through the first authentication module when the user device is authorized. A digital rights management server communicates a request for content to a content delivery module using the address of the content delivery module. The content delivery module communicates content to the user device corresponding to the selection signal. The user device displays content on the display associated with the user device.
Abstract:
A method, apparatus, article of manufacture, and a memory structure for securely providing data for use by a hardware device of a receiver. The method utilizes a product provisioning key (PPV) held secure from other entities that can be unlocked and used with a secret value securely and unchangeably stored in the hardware device.
