摘要： A mask function that replaces at least part of information, such as video data, audio data, and sub-picture data, with invalid data is provided in an information recording/reproducing apparatus. Both of a personal computer (PC) and the information recording/reproducing apparatus are provided with features in which the information is encrypted on a sending end, exchanged between the sending end and a receiving end, and decrypted on the receiving end. Authentication is performed between the PC and the information recording/reproducing apparatus: when the authentication succeeds, the information is transferred from one end where the information is encrypted to the other end where the information is decrypted; when the authentication fails, the information recording/reproducing apparatus applies the mask function to the information read from a storage medium or to the information to be written transferred from the PC to the storage medium.

摘要： It is an object to provide an efficient transfer of content data. In a case of transferring the content data from a data transfer device on a primary recording medium side to a data recording device to record the content data in a secondary recording medium, a data compression system and a bit rate that are conformable to the data recording device are compared with a data compression system and a bit rate of the content data to be sent, so that a required transfer processing is brought into realization according to a result of the comparison. For instance, when both the data compression systems are equal, and the bit rate of the content data is not more than the bit rate that is conformable to the data recording device, the content data is sent as it is in an encrypted compressed data state.

摘要： The information reproduction device for reproducing the contents information based on the license information added to the contents information and required for reproducing the contents information, includes a determining section for determining whether the encrypted contents information is the officially copied contents information or privately copied contents information based on the contents of the license information, and a reproduction section configured to reproduce the contents information determined as the privately copied contents information by the determining section under more severer restrictions than the officially copied contents information. Thus, the contents copied by the proper route (officially copied contents) can be distributed in a more advantageous form than the contents copied without proper authorization.

摘要： A signal transmission method applicable to prevention of modification or alteration of the playback mode information, such as copying management information or charging information. The playback mode information form a terminal 15P is data-converted for ciphering by a playback mode information appendage circuit 14 in a header appendage circuit 13 responsive to the key information from a terminal 15K and the resulting information comprised of the data and the playback mode information is outputted. The reproducing side effects data conversion on the ciphered playback mode information for deciphering, by a playback mode information detection circuit 26 in a header separation circuit 25, using the key information from a terminal 27K, for taking out the original playback mode information at a terminal 27P.

摘要： The operating and other procedures of a disk or recording medium application system of the type for which a network is used are simplified. Disks or recording media have auxiliary data recording areas, where different IDs for individual disks, and/or cipher keys and/or decoding keys for ciphers are recorded in advance in a factory. By using the IDs to release the soft ciphers, using the cipher keys when sending the ciphers, and using the decoding keys when receiving the ciphers, user authorization procedures are simplified.

摘要： A signal of a first code string, in which a code string in a predetermined format is partially replaced with dummy data, is transferred to a code string rewriting unit via a code string decomposition unit. A signal of a second code string for replacing the dummy data in the signal of the first code string is transferred to a control unit, and the amount of dummy data in a mid-range spectrum is calculated in a mid-range spectrum dummy data amount calculation unit. The control unit transfers data for replacing the dummy data to the code string rewriting unit, where the dummy data in the first code string is rewritten therewith.
