摘要： An optical recording medium, a data recording or reproducing apparatus, and a data recording or reproducing method used by the data recording or reproducing apparatus. In a method of recording data on an optical disc, each of a plurality of error correction code (ECC) blocks is divided into a plurality of partitions. Next, data from the partitions is interleaved so that each of the ECC blocks is alternately and equally selected to generate a recording block. The generated recording block is modulated and recorded on an optical disc. As a result, the optical recording medium, the data recording apparatus, and the data recording method used by the apparatus are compatible with the format of a conventional digital versatile disc (DVD) and have higher error correction rates. In a reproducing method, the recording block is deinterleaved.

摘要： A decoding method and an apparatus operate by performing error correction on code words of an error correcting code block in one direction selected from a row direction and a column direction, indicating in error flags the remaining code words except at least some code words from code words having uncorrectable errors, and performing error correction on code words in the other direction based on the error flags. Accordingly, errors that have been conventionally considered as being uncorrectable may now be corrected.

摘要： A key management, user registration and deregistration for a digital rights management (DRM) system in a home network, using a hierarchical node topology. In the key management, node information is generated by allocating a pair of keys (a public key and a private key) to each node. A node tree is made by generating link information using the pair of keys and a content key. The link information is delivered from an upper node to a lower node using the node tree. The link information is obtained by encrypting a private key of a ‘TO’ node using a public key of a ‘FROM’ node. Accordingly, it is possible to realize a DRM system that protects content and easily accomplishes a binding mechanism and a revocation mechanism.

摘要： Provided is a method of controlling content access in a home network. The method includes: (a) defining a predetermined sub group and allocating a sub group key for the sub group; and (b) checking whether a user belongs to the sub group and transmitting the sub group key to a user device requested by the user, wherein the user device obtains an encrypted content key using a domain key and the sub group key. Since a content key is twice encrypted using a domain key and a sub group key and transmitted to a user device, it is possible to provide authorized content access to a user.
