    Abstract: Management of rights to content is provided within an authorized domain. In a single authorized domain, where a plurality of domain interfaces are protected using a common rights management system, a copy of particular content may be allowed to be provided on all devices or only on specific devices coupled to the domain via the interfaces. Copy protection information, for outputs to external devices not protected by the common rights management system, is also specified. Rules can be provided for specifying whether particular content may be copied or moved to another protected domain. A number of rendering devices permitted to render the content simultaneously may be specified. Content rules are provided for use in managing rights to content within an authorized domain. Such rules can be associated with content that is persistently stored by a consumer device, as well as with content that is only rendered by a consumer device.

    Abstract: In embodiments of secure progressive download for media content playback, a client device (128) implements a media player (142) and a proxy application (144). The proxy application is implemented to receive media content (136) from a media server (126), and the media player controls playback of media content (148) on the client device. The proxy application receives the media content (136) encrypted and formatted by the media server for playback by the media player, and the proxy application initiates storing segments of the media content (148) as encrypted media content on the client device. The proxy application also requests an encryption key (124) to decrypt the encrypted media content for playback by the media player. The proxy application receives the encryption key from a key server (122) and stores the encryption key on the client device to decrypt the encrypted media content when requested by the media player.

    Abstract: A Service Key Delivery (SKD) system for delivering a service keys to client devices in a communications network. The delivered service keys are operable to be used to decrypt an encrypted key operable to be used to decrypt an encrypted digital content. The SKD system includes a data input interface for receiving a distribution time frame for the keys and a listing of client device identifications. The SKD system also includes a scheduling module to partition at least part of the distribution time frame into a number of time slots in which the number may be based on a variety of factors. The scheduling module assigns the time slots in the partitioned part of the distribution time frame to the client devices based on the identifications in the listing. The SKD system also includes a message generator configured to send key delivery messages to the client devices.

    Abstract: A method for registering a first device with a second device over a wireless network includes receiving a registration request from the first device and sending one or more user input choices to the first device. The user input choices each specify a user input action available though a user interface associated with the second device. A device description describing the second device is sent to the first device in a manner that allows it to be presented to the user by the first device. At least one of the user input actions are sequentially received through the user interface in response to instructions provided to the user by the first device. The first device is registered with the second device if the user input actions received by the second device correctly reflect the instructions provided to the user by the first device.

    Abstract: A domain controller is provided for use with a content source and a media device. The content source can provide encrypted content and rights data corresponding to the encrypted content. The media device can provide a request for the encrypted content and the rights data. The domain controller includes a communication portion, a digital rights management portion and a memory portion. The communication portion can engage in a first bi-directional communication with the content source and can engage in a second bi-directional communication with the media device. The digital rights management portion can receive the rights data. The memory portion can store the encrypted content. The second bi-directional communication includes an authorization and authentication communication between the communication portion and the media device, a secure move message exchange between the communication portion and the media device and a content download from the communication portion to the media device.

    Abstract: A method is provided by which a client device obtains authorized access to content delivered over a content delivery network. The method includes receiving an entitlement management message (EMM). The EMM includes at least one cryptographic key and a device registration server certificate ID (DRSCID) identifying a currently valid device registration server (DRS) public key certificate. The DRSCID obtained from the EMM is compared to a stored DRSCID value. An entitlement control message (ECM), which includes an encrypted traffic key for decrypting content, is received. If the DRSCID obtained from the EMM is determined to match the stored DRSCID, the traffic key is decrypted with the cryptographic key or a key derived from the cryptographic key to thereby access the content.
