    摘要： A configuration is realized that allows reproduction control on the basis of age at the time of reproduction by recording information regarding age permitted for reproduction corresponding to media recorded content. A clip AV stream file storing content to be reproduced acquired from input data including MPEG-2 TS format data or MMT format data and information regarding age permitted for reproduction corresponding to content acquired from the input data are placed into a playlist file, a clip information file, a usage control information file, or other file and recorded in media. A reproduction apparatus reads the information regarding age permitted for reproduction corresponding to the content to be reproduced from the playlist file or other file and compares the information regarding age permitted for reproduction with user's age information, thus allowing for content reproduction to be controlled.

    摘要： An optical axis or a diameter of light of even a light beam having a non-uniform intensity distribution is stably obtained. An outer shape of a range of a light intensity having a specified ratio with respect to a total light intensity on a cross-section of a light beam is obtained. An approximate circle is obtained from this outer shape. For example, the approximate circle is calculated by using the least-squares method. An optical axis and/or a diameter of light of the light beam is obtained on the basis of this approximate circle.

    摘要： A configuration capable of performing reliable source analysis of illegal copy content using content in which a reproduction path is settable is implemented. Content in which an individual segment region including a plurality of pieces of variation data which include different identification information embedded therein and are decryptable using different keys and a common segment region including single data are provided, and variation data is configured with an aligned unit is set. A content reproducing device calculates a reproduction path by applying a device key and selects and reproduces an aligned unit corresponding to the reproduction path on the basis of a variation data identifier recorded in an adaptation field in a plain text region at the head of a plurality of aligned units constituting the variation data.

    摘要： A configuration is implemented that converts MMT format data to MPEG-2 TSV format data for recording onto medium, thereby permitting copy control in compliance with the initial copy control information. MMT format data with copy control information set therein is input and converted to MPEG-2 TS format data for re-cording onto information recording medium. The copy control information recorded in the service description table (MH-SDT) stipulated by the MMT format is acquired and, in accordance with predetermined conversion rules, used to generate the copy control information for recording to the program map table (PMT) stipulated by the MPEG-2 TS. For example, the EPN and CCI values to be recorded to the PMT are determined in accordance with the conversion rules.

    摘要： The present disclosure realizes a structure that can unify the management of the storage block for the encryption key to be used in decrypting encrypted content stored in a memory card. This structure includes: an information processing apparatus that stores content into an information storage device such as a memory card including an access allowed block based on an access right check made on each block, and uses the content; a content usage managing server that provides content usage permission information to the information processing apparatus; and a content correspondence information providing server that provides the encryption key to be used in decrypting the encrypted content stored in the information storage device. The content usage managing server determines the block for storing the encryption key and notifies the content correspondence information providing server of a block identifier that is the identifier of the determined block, and the content correspondence information providing server performs a process to write the encryption key into the block corresponding to the received block identifier.

    摘要： A configuration in which usage control that is substantially similar to content usage control in a copy source medium can be performed in a content copy destination is implemented. A data processing unit that performs a copy process of recording data recorded on a first medium on a second medium records encrypted content in the first medium on the second medium, without decrypting the encrypted content. In addition, the data processing unit converts a CPS unit key file recorded on the first medium to generate a converted CPS unit key file and records the converted CPS unit key file on the second medium. Further, the data processing unit acquires an MKB not requiring KCD, which is capable of directly calculating a media key using only a device key, without using key conversion data (KCD) recorded on the first medium, from a server and records the MKB not requiring KCD on the second medium.
