摘要： A method and apparatus for providing secured content distribution using a media hub is disclosed. In one embodiment, conditional access encrypted content is received at the media hub. The conditional access encrypted content is decrypted. The content is re-encrypted in accordance with a unique tier associated with the media hub and one or more devices in response to a request from at least one device associated with the unique tier. The re-encrypted content is provided to the at least one device in response to the request from the at least one device associated with the unique tier. A method and apparatus for providing secured content distribution is disclosed. In one embodiment, unit addresses (UAs) of all components within a home media architecture are obtained. A unique key is generated for the home media architecture using public information from the UA of each component. A message including the unique key is distributed to each component of the home media architecture. A method and apparatus for providing secured content distribution is disclosed. In one embodiment, UAs of all decoders within a home media architecture are obtained. A unique key is generated for the home media architecture using public information from the UA of each decoder.

摘要： The present invention discloses an apparatus and method for defining and enforcing rules of transition between two security domains, e.g., a transport domain and a persistent security domain. In turn, a border guard, e.g., a security device, is provided between these two domains that enforce rules for transition between the two security domains. This novel approach of defining a transport domain and a persistent security domain simplifies the classification of the digital content and its movement through the system. Namely, the border guard once established between the two systems can enforce DRM rules associated with how contents are moved between the two domains.

摘要： The present invention discloses a system and method for providing a secured system time reference to a subscriber device, e.g., a set top box or a receiver. In one embodiment, the system time reference is provided in a secure system time message that is broadcasted to a plurality of subscriber devices. Each subscriber device has a security device or software application that is capable of determining whether the received system time reference is legitimate. If the system time reference is determined to be legitimate, a local time reference is synchronized with said received system time reference.

摘要： A transaction protocol for communicating between an encryption renewal system communicably coupled to one or more video on demand systems via a communication network. The encryption renewal system permits pre-encrypted content to be accessed by clients of the video on demand systems. The protocol comprises, receiving, by the encryption renewal system, a request transaction document having a first format from the video on demand system; parsing the request transaction document to retrieve data from the request transaction document; generating a request object code in a second format for processing by encryption renewal system, the request object code based on the data in the request transaction document; responsive to processing of the request object code, generating a response object code having the second format; converting the response object code to a response transaction document having the first format; and forwarding the response transaction document to the video on demand system.
