  • Patent number: 8176534
    Abstract: A method and apparatus are provided for enabling a Universal Plug and Play (UPnP) device to be automatically provisioned to access services without the need for manual interaction. In accordance with the invention, when a UPnP device needs to be provisioned, it automatically obtains pre-provisioning information from a provisioning device on the home network, and uses the pre-provisioning information to interact with the provisioning device to cause the UPnP device to be provisioned. The provisioning enables the UPnP device to access services, including digital rights management (DRM) services, over a network.

  • Publication number: 20110235801
    Abstract: A source device determines content rights for encrypted content in the first encoding standard using a first rights data file. The source device creates a second rights data file for transcoded content in the second encoding standard. The source device performs a key management operation including communicating a decryption key for the encrypted content in the first encoding standard to a transcoder. The source device transfers the encrypted content in the first encoding standard to the transcoder. The transcoder decrypts the encrypted content, transcodes the content from the first encoding standard to the content in the second encoding standard, and re-encrypts the content in the second encoding standard using a second encryption key. The transcoder then transfers the encrypted content in the second encoding standard to an indicated device.

  • Publication number: 20110150214
    Abstract: A method of viewing a content item is provided. The method includes receiving an encrypted content item and a network address of a key management system from a primary client device over a communications network. A session key is obtained over the communications network and the primary client device is notified that the session key has been obtained. An encrypted version of a content key is received over the communication network to decrypt the content item and content rights that determine access to the content item. The content rights restrict the content item from being rendered unless it is rendered in coordination with the rendering of the content item by the primary client device. The encrypted version of a content key is decrypted with the session key. The content item is rendered in accordance with the content rights by decrypting the content item with the content key.

  • Patent number: 7953668
    Abstract: The present invention discloses an apparatus and method for reserving a set of requested rights. In one example, the digital rights data associated with digital content information is found in a remaining rights file using a license index. A portion of the digital rights data is subsequently reserved. A determination is made as to whether a content download associated with the digital content information is successful. If the content download is unsuccessful, then the reserved portion of the digital rights data is cancelled. Alternatively, if the content download is successful, then the remaining rights file is updated to reflect a use of the portion of the digital rights data.

  • Patent number: 7818792
    Abstract: A method and system (100) for providing third party authentication when requesting content and/or services from an application server (106). The method is applicable to key management protocols that utilize the concept of tickets. The method and system include a client (102) being coupled with a third party application server (107), wherein the client submits a request for content from the third party application server and the third party application server returns requested information and corresponding authentication. The client further couples with a first application server (106), wherein the client submits a key request (KEY_REQ) including the third party server information and corresponding authentication to the first application server. The first application server authenticates the third party server information and verifies client authorization based on third party information.

  • Publication number: 20100217964
    Abstract: A method, device and system for controlling JTAG interface enablement within a communication device. The JTAG interface can be selectively enabled based on the receipt of an encrypted access token generated by an access token server. The access token server generates the access token in response to an end user providing appropriate device-specific information. The access token includes appropriate information that, upon appropriate authentication and decryption, can temporarily device bind the boot code image of the device in a manner that enables the JTAG interface. Alternatively, the access token includes appropriate information that instructs the general purpose processor to choose between JTAG interface enablement information and JTAG interface disablement information for use with the boot code image of the device. The access token can include expiration information that causes an enabled JTAG interface to revert back to its disabled status upon expiration of the access token.

  • Publication number: 20100167656
    Abstract: A device configured to communicate with a second device may register a second device using one of multiple registration modes including a domain-registration mode, a device-registration mode, and a no-registration mode. The domain-registration mode allows the second device to register with the device and at least one other device registered with the device, the device-registration mode allows the second device to register with the device and with no other devices, and the no-registration mode does not allow any device to register with the device. The device receives a selection of one of the multiple registration modes and places the device in the selected registration mode.

  • Publication number: 20100164693
    Abstract: A targeted discovery between a first device and a second device in a network, in particular, a WHDI network, provides discovery for an identified device or a group of identified devices. The targeted discovery determines an identifier for a second device or a group of devices that the second device belongs to, and sends a device discovery message to the second device using the identifier for the second device when the second device is configured to respond to the device discovery message if the device discovery message includes the identifier for the second device. The first device receives a response to the device discovery message from the second device and can start further communication with the second device.

  • Publication number: 20100138900
    Abstract: A service control method, device and system for allowing secure, remote access of protected IP-based content delivered over an IMS-based network to one or more devices within a home network. The method involves a remote access device transmitting a remote access request to a service control application in the IMS-based network, the service control application authorizing the remote access request based on a number of criteria, and forwarding the remote access request to the home network. The forwarded remote access request includes information that allows protected content requested by the remote access request to be transmitted from a home network device in the home network to the remote access device upon appropriate verification of the remote access device by the home network device using home network device DRM schemes. Remote access of the protected content can be allowed by relaxing proximity restriction requirements of the home network.
