    摘要： In general, in one aspect, a method is disclosed that includes storing a superset of data available to a client having non volatile memory (NVM) on a distant hard drive. A subset of the data is maintained in the NVM on the client. The client controls the data stored on the distant hard drive and the data maintained in the NVM. A single merged directory/file tree image is generated for the content maintained in the NVM and the distant hard drive that is accessible to a user of the client and applications running thereon.

    摘要： In general, in one aspect, the disclosure describes a method that includes maintaining a superset of data available to a client having non volatile memory (NVM) on a distant hard drive. A subset of the data is maintained in the NVM on the client. The client controls the data maintained on the distant hard drive and the data maintained in the NVM. A single merged directory/file structure is generated from a directory/file structure of the superset and a directory/file structure of the subset. The directory/file structures overlap and the single merged directory/file structure merges the overlapping directory/file structures so only the directory/file structure of the subset is presented for the overlap. The single merged directory/file structure is presented to a user of the client and applications running thereon.

    摘要： Protected content distribution is accomplished by a first entity generating a set of asymmetric key pairs, creating a plurality of sets of private keys by selecting a combination of private keys from the set of asymmetric key pairs for each created set, and distributing the sets of private keys to playback devices. A second entity produces protected content including encrypted content and a public key media key block, encrypts a symmetric content key with each public key in the set of asymmetric key pairs to form the public key media key block and encrypts a content title with the symmetric content key to form the encrypted content. A playback device stores one set of private keys, receives the protected content, and decrypts and plays the content title stored in the protected content when a selected one of the set of private keys stored by the playback device successfully decrypts the encrypted symmetric content key stored in the public key media key block of the received protected content.

    摘要： A video source device includes a cipher unit. The cipher unit includes a block cipher and a stream cipher. The video source device uses the block cipher to generate at least one cipher key for use by the stream cipher to generate cipher bits for ciphering video to be transmitted to a video recording device. The video source device further provides n bits of copy control information to the video recording device. The video source device incorporates the n-bit copy control information as part of an initialization value, and initializes a register of a round function of the block cipher with the initialization value. The video recording device also includes a cipher unit of like kind, and operates the block and stream ciphers in like manner to decipher the ciphered video received from the video source device. Upon receiving the n-bit copy control information, the video recording device also forms an initialization value and initializes a corresponding register of the corresponding round function of its block cipher. Accordingly, protection is provided to the copy control information.

    摘要： A method and apparatus for automatically delivering data files (e.g. television and movies) via a personalized channel to a user, that are based on a user's profile and viewing habits, are provided. A client receives meta-data broadcasts from a server system that includes descriptions of a plurality of data files currently being broadcasted or to be broadcast by the server system. In response to a content rating table that is based on a user's profile and viewing habits, a data file is automatically selected. The selected data file is displayed on a personalized channel on a display device to the user. The selected data file can be, for example, a currently broadcasting data file or a data file stored in a cache memory of the client. Thus, the user only needs to tune to his or her personalized channel to view personalized content.

    摘要： A method and apparatus for determining the scope of a content domain for ensuring that a content stream is not re-routed to an unauthorized display device. The apparatus includes a content source device, which supports multiple display outputs coupled to one or more content sink devices. A content source application generates and provides a content stream to a hardware interface which securely transmits the content stream to a protected content sink device using a content protection protocol. The content source application utilizes certain status information to ensure that the content stream is not re-routed to an unprotected or unapproved content sink device. The source application requests the updated session identification code from the transmitter/codec unit using the content protection protocol which is compared against the expected session identification code to ensure that the content display stream has not been re-routed to an unprotected content sink device.
