The home and remote locations are serviced by respective first and second head ends of the system. The subscription service ... 07/19/07 - 20070165854 - Secure system, secure device, terminal apparatus, method and program therefor IC card (300) supplies an encryption key which enables content use, to a terminal apparatus (200) belonging to a domain made up of terminal apparatuses (200) which share the IC card (300). The IC card (300) includes: an extra-domain usage rule holding unit (305) which stores a rule for use ... 06/21/07 - 20070140488 - Restriction of broadcast session key use by secure module decryption policy A method is provided for restricting or enhancing broadcast content access on a per-subscriber basis across a population of subscribers, all of whom have a valid content access key to such content, without necessitating changes to the current standard schemes and protocols for distributing content access keys and broadcasting the ... 06/14/07 - 20070133796 - Broadcasting receiving apparatus and broadcasting receiving method Disclosed a digital-broadcasting receiving apparatus including: a scramble judgment member, a decode judgment member, a first registration member to register the sub-channel as a viewable channel when the decode judgment member judges that the broadcast data can be decoded, a second registration member to register the sub-channel as a viewable ... 05/24/07 - 20070116279 - Secure terminal A secure terminal comprises: primary means consisting of processing means, data and program storage means, security means and data input means, wherein the components of the primary means are interconnected by a first data bus; peripheral means consisting of printing means, means for reading from/writing to a card and means ... 04/12/07 - 20070081669 - Information processing apparatus, information processing method, and computer program An information processing apparatus is provided. The information processing apparatus includes a cryptographic processor configured to generate encrypted data associated with a content management unit by executing encryption using a unit key associated with the content management unit, the content management unit being defined as a unit for controlling usage ... 12/14/06 - 20060280301 - Encryption scheme for streamed multimedia content protected by rights management system A stream of content has multiple sub-streams, where each sub-stream comprises a part of the content and is divisible into logical blocks bounded by intrinsic partitions. For each sub-stream, a specification of the logical blocks bounded by the intrinsic partitions is defined and the sub-stream is divided into the logical ... 10/26/06 - 20060239457 - Selection of 1-out-of-n scrambled code blocks Apparatus and method to determine selection of a scrambled data channel before receipt of an entire data block. An initial portion of a block of data received in one of a plurality of scrambled data channels is decoded, then re-encoded. A value is computed related to the number of mis-matched ... 08/18/05 - 20050180568 - Time-multiplexed multi-program encryption system A system and method are described for greatly increasing the number of services that can be encrypted with existing conditional access equipment. The method is most useful when many digitally compressed programs are encrypted at the same time. Only the most critical components of each compressed video, audio, or data ... 06/23/05 - 20050135618 - Methods and apparatus for mixing encrypted data with unencrypted data Methods and apparatus for mixing encrypted data with unencrypted data are disclosed. A disclosed system receives data from a first media source, such as DVD-Audio content, and encrypts the data from the first media source using a key stream to form an encrypted data stream. The disclosed system may separate ... ### FreshPatents.com Support |
