摘要： An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus the error correction capability in a burst cutting area of an optical disc can be improved.

摘要： Four ECC blocks are recorded in a burst cutting area of an optical disc. Each ECC block is constituted by a BCA content code of 1 byte, content data length of 1 byte, and content data of 14 bytes. Of the BCA content data, the leading 6 bits are used for application ID and the remaining 2 bits are used for block number. Disc ID is stored in the content data. Since the four ECC blocks exist, the optical disc can be managed individually by four applications at the maximum. Thus it becomes possible to manage the same optical disc by a plurality of applications.

摘要： A content protection system prevents illegal key acquisition, without checking uniqueness of device keys. The content protection system includes a key data generation apparatus and a user terminal. The key data generation apparatus converts first key data, which is for using content, based on a predetermined conversion rule, thereby generating second key data, encrypts the second key data using a device key held by valid terminals, and outputs the encrypted key data. The user terminal obtains the encrypted key data, decrypts the encrypted key data using a device key held by the user terminal, thereby generating second key data, converts the second key data based on a re-conversion rule corresponding to the conversion rule, thereby generating the first key data, and uses the content with use of the generated first key data.

摘要： A digital work (102) and copyright management information (103) for the digital work are recorded on an information recording medium (101) by altering a shape, a position or a pattern (104,105) of recording mark edges of the digital work. Alternatively, a decryption key for the right management information is recorded on an information recording medium on which the copyright management information has been recorded encrypted, by altering the recording mark edges of the copyright management information. Alternatively, a check code for the copyright management information is recorded on the information recording medium by altering the recording mark edges. The check code is checked when the copyright management information is read, thus detecting illegal use of the copyright management information.

摘要： An optical disc having a plurality of sectors, each of which includes a plurality of frames. Sub information bit value '0' or '1' is assigned to the plurality of frames constituting a sector, excluding the first and last frames. Edge positions are displaced so that leading/lagging errors appear in accordance with a certain rule when data fields of the frames to which sub information bit value '1' is assigned are read. Edge positions are displaced so that leading/lagging errors appear in accordance with a reversed rule of the certain rule when data fields of the frames to which sub information bit value '0' is assigned are read.

摘要： The present invention has an objective of realizing compatibility of an optical disk having a high resolution video signal recorded thereon and a system for reproducing the optical disk, with a conventional system for producing a standard resolution video signal. A high resolution video signal is divided by video division means into a main signal and a sub signal, and the main signal and the sub signal are MPEG-encoded. The stream of the main signal and the stream of the sub signal are divided into 1 GOP or more of frames. First interleave blocks 54 each including 1 GOP or more of the stream of the main signal and second interleave blocks 55 each including 1 GOP or more of the stream of the sub signal are recorded on an optical disk 1. A high resolution reproduction apparatus reproduces both the first and second interleave blocks to obtain a high resolution video output. A non-high quality picture reproduction apparatus reproduces only the first or second interleave blocks to obtain a standard resolution video output.

摘要： An optical disc capable of disabling reproduction of sub-information even when the sub-information as a content encryption key is directly recorded onto another optical disc. Sub-information is recorded onto the optical disc by slightly deforming the recording mark according to the pseudo random number time series having as an initial value the medium ID which is medium unique information read out. Thus, it is possible to record sub-information unique to the medium. Even if the sub-information is copied directly to another optical disc, the initial value of the pseudo random number series varies depending on the medium and sub-information which has been copied in an unauthorized way cannot be reproduced.
