摘要： PROBLEM TO BE SOLVED: To solve the problem that an executing device for executing playback has to be equipped with a high-performance processor, because verification of correctness of information is executed in parallel with the playback of the content, and therefore processing load becomes high during the content playback. SOLUTION: The processing load involved in processing of verification is reduced by using, for the verification, only a predetermined number of encrypted units selected randomly from among a plurality of encrypted units constituting encrypted contents recorded on a DVD. Further, the accuracy of detecting unauthorized content can be improved to some extent by randomly selecting the predetermined number of encrypted units every time the verification is performed.

摘要： PROBLEM TO BE SOLVED: To provide a recording apparatus and reproduction apparatus that are able to prevent illegitimate use of contents. SOLUTION: The recording medium stores therein a medium inherent number in the unrewritable area. The recording apparatus writes media key data and encrypted contents onto the recording medium. The media key data includes a plurality of encrypted media keys generated by, for each of disabled reproduction apparatuses, encrypting a media key using a device key of the disabled reproduction apparatus respectively, and, for each of revoked reproduction apparatuses, encrypting detection information using a device key of the reproduction apparatus respectively. The reproduction apparatus decrypts the encrypted media key using a device key to generate a decryption media key, judges whether the decryption media key is the detection information or not, and prohibits the encrypted content recorded on the recording medium from being decrypted when having judged in the affirmative.

摘要： PROBLEM TO BE SOLVED: To provide an information recording medium in which a plurality of real time data are simultaneously recorded and reproduced, and to provide a method for simultaneously recording and reproducing, and an information recording and reproducing device. SOLUTION: Data recorded in a region having a size that is equal to or larger than a minimum size meeting the reproducing condition to enable four accesses are reproduced and the data are recorded in a region having a size equal to or larger than the same size. When the amount of data in a buffer is full, it is switched to recording. Conversely, when the buffer is empty, it is switched to reproducing. Thus, reproducing and recording are alternatively conducted. Therefore, the information recording medium which guarantees simultaneous recording and reproducing, the simultaneous recording and reproducing method and the information recording and reproducing device are obtained.
