摘要： Method and apparatus for transferring protected content between digital rights management systems is described. One aspect of the invention relates to importing content from an upstream digital rights management (DRM) system into a device in a downstream DRM system. Data is received that associates at least one device in the downstream DRM system with a rights issuer module (RIM). Authenticity of the data is verified as originating from an entity in a trust hierarchy of the device. If the data is authentic and the device is one of the at least one device associated with the RIM, a ciphertext version of the content and a corresponding content license is accepted from the RIM.

摘要： A method of providing permissions to consume content objects within a domain includes creating a domain and a domain membership rights object for each member. The domain facilitates the sharing of content objects amongst the members of the domain. The domain membership rights objects for each member include permissions for each member in the domain to consume content objects in the domain.

摘要： The present invention is directed to methods and apparatus for improving error indication performance in systems employing low-density parity check (LDPC) codes. In one aspect, a method and apparatus for providing error indication based on full LDPC parity check re-encoding are provided. In an embodiment, an LDPC encoder is employed at the receiver to re-encode the parity bits. In another embodiment, the parity bits are re-encoded recursively based on information readily available at the decoder of the receiver. In another aspect, a method and apparatus for providing error indication based on partial LDPC parity check re-encoding are provided. In an embodiment, partial checksum information is determined based on the decoder output and used to provide error indication. In a further aspect, a hybrid CRC checking and LDPC parity check re-encoding approach is provided. This approach further enhances error indication performance by reducing the miss probability compared to pure LDPC parity check re-encoding.

摘要： A method and an apparatus are provided for use in a user device for limiting the ability of the terminal of the user device to replay protected content. The low-level key that is used by the decryption component of the terminal to decrypt content is transient in that it expires if at least one predetermined expiration criteria is met. After they key has expired, it is no longer valid and thus cannot be used by the decryption component to decrypt protected content. Limiting the ability of the terminal to replay protected content is preferably accomplished in a way that does not affect the ability of the terminal to play and replay unprotected content.

摘要： Methods for ex vivo perfusion of organs (and/or tissues) with a perfusate designed to condition the organ with the desired effect being that upon transplant, said organ, having been administered said perfusate, is less likely to experience delayed graft function, deleterious effects of ischemia/reperfusion injury, including inflammatory reactions, and/or other detrimental responses that can injure the organ or recipient including precipitating or enhancing an immunological reaction from the recipient with the potential of compromising the graft's and/or recipients short teen and/or long term health and proper functionality while monitoring, sustaining and/or restoring the viability of the organ and preserving the organ for storage and/or transport.
