    摘要： A recording device comprises a memory unit configured to be communicationable with an external device and to record key data for encryption of content data through an authentication process, and a controller which controls the memory unit. The memory unit comprises a normal recording unit which is accessible from the exterior through the controller without an authentication process, a protected recording unit which is accessible from the external device when authentication of a first authentication process completes, and a writing restricted/protected recording unit which is accessible from the external device when authentication of a second authentication completes and is unwritable and unaccessible from the external device when authentication of only the first authentication process completes.

    摘要： In a forward error correction method and a forward error correction addition apparatus, error correction is performed on the basis of data, to which forward error correction code is added, transmitted through a network to output decoded data. The data transmitted through the network includes information bits represented by an information bit matrix with n rows and m columns (n, m are natural numbers), and redundancy bits represented by an odd number of redundancy information bit rows and an odd number of redundancy information bit columns based on the information bit matrix, which are provided in the row direction and in the column direction of the information bit matrix respectively. The redundancy bits are the forward error correction code.
