Abstract: A controller of a recording device issues a secure command to a storage device, and then waits the time estimated necessary for the storage device to execute the secure command before issuing the next secure command. When a controller of the storage device is executing the previous command, it notifies the recording device of being in process. When the previous command has been completed normally, the controller moves to the next process. Information for estimating the execution time of the command is obtained from the storage device in advance.

Abstract: An information recording apparatus is provided whereby in the reproduction of broadcasting information, the broadcasting information can be recorded so that the combination and so on of contents included in the broadcasting information can be recognized without the need for reproducing the broadcasting information itself. An information recording apparatus for recording broadcasting information constituted of a packet which has a predetermined amount of information and includes different types of contents, each type including one or more contents, the apparatus including a controller 8.

Abstract: A technology is provided to improve tamper resistance in encrypting data to be secured and inputting/outputting the data between a recording device and a host device. When the recording device issues an input/output command to a storage device to input/output data to be secured, the recording device attaches an ID to the command to identify to which cryptographic input/output processing the command belongs. Upon reception of a sequence command, the storage device receives the command if its ID has been allocated and the command is verified to have been issued in the correct sequence. The sequence ID is used to identify a process system while appropriately managing the steps of executing commands.

Abstract: A controller in a hard disk serving as a data storage device stores a license including a content key for decrypting encrypted content data E and others in a secure data storage portion. The license is managed in the secure data storage portion in accordance with a LBA, and the LBA for storing the license, which is being processed for transmission, is stored as a log in a log memory of the secure data storage portion. When a failure occurs during the transmission processing, the license, which was being processed for transmission, is specified based on the LBA stored in the log memory.

Abstract: An information recording apparatus is provided which can record broadcasting information so as to accurately identify and reproduce broadcasting information to be reduced while increasing convenience in reproducing the broadcasting information. Time control is performed during reproduction in allocation units ALU based on the receiving time of the first packet and the receiving time of the last packet in the allocation unit ALU included in the broadcasting information. The allocation unit ALU includes a plurality of packets. Time control is performed also in access units, each of which includes an I picture, based on the display time information or the receiving time information of the I picture included in the packet.

Abstract: An information editing apparatus is provided which can prevent a thumbnail image, which shows the contents of recorded information recorded on an information recording medium, from being accidentally changed by a misoperation of the user. The information editing apparatus includes a deciding device 8 for deciding whether a thumbnail image can be changed or not based on change permission information, which indicates whether a change can be made on the thumbnail image showing the contents of recorded information recorded on a recording medium 1. When the deciding device 8 decides that a change is not permitted, a change of the thumbnail image is prohibited.

Abstract: First information is divided into equal-size information pieces. Serial numbers are assigned to the information pieces, respectively. An encryption key is generated from a base number and a variable number varying for each of the information pieces. The base number is common to an information range managed by one licence. The first information is encrypted on a block-by-block basis in response to the encryption key to get encryption-resultant information for every predetermined minimum information unit smaller than the sizes of the information pieces. The encryption-resultant information is recorded on a recording medium. A determination is made as to logical addresses of heads of portions of the recording medium which are loaded with portions of the encryption-resultant information corresponding to the respective information pieces. Second information representing a correspondence relation between the determined logical addresses and the assigned serial numbers is recorded on the recording medium.

Abstract: A recording area of a hard disk is managed by units. Each unit comprises physically continuous recording regions having predetermined size, and usage status of the unit is stored in an allocation unit (AU) management table. Data requiring a real time processing is stored in each unit. When the usage status of the unit is changed or modified due to the recording or deletion of data, the AU management table is updated and then information indicative of the fact that the AU management table has been updated is recorded. An apparatus where the final change is made is detected at the time the hard disk is inserted or a file system is initialized. And if the apparatus which last made the change adopts the file system which does not use the AU management table, then the table is reconfigured so as to retain the consistency of the AU management table.

Abstract: A packet recording/reproducing system is provided which records or reproduces packets on or from tracks formed in time sequence on a magnetic tape. In a recording operation, the packet recording/reproducing system adds to input packets time stamps whose values are synchronous with packet arrival time control clocks produced by the system. The timing with which the packets are recorded on the magnetic tape is controlled by the arrival time control clocks so that a given number of the packets inputted at high data rate are recorded within a one-track area, a two-track area, or a one-track over area defined across at least two of the tracks, thereby minimizing the loss of capacity of the magnetic tape.

Abstract: First information is sent from a contents-information receiver apparatus to a contents-information sender apparatus. The first information includes a combination of certificate information and second information for the contents-information receiver apparatus. The first information further includes a signal of a signature for the combination of the certificate information and the second information. In the contents-information sender apparatus, a determination is made as to whether the combination of the certificate information and the second information in the first information is correct or wrong in response to the signal of the signature in the first information. In the contents-information sender apparatus, the second information is extracted from the first information before being stored. The second information for the contents-information receiver apparatus is sent from the contents-information receiver apparatus to the contents-information sender apparatus.
