摘要： A data transfer apparatus referred to as a primary-recording-medium apparatus implements proper system operations by acquisition of information on a secondary recording medium mounted on a secondary-recording-medium apparatus to serve as a destination of a transfer (or a check-out) of a content. If a medium adopting its own unique management technique as is the case with a mini disc is used as the secondary recording medium serving as a destination of a check-out, the primary-recording-medium apparatus acquires information on the secondary recording medium from the secondary-recording-medium apparatus, which is typically a data-recording apparatus. The information includes an indicator as to whether or not the secondary recording medium has been mounted on the data-recording apparatus, the name of the secondary recording medium, the name of each content stored in the secondary recording medium, the number of contents stored in the secondary recording medium and attributes of each content stored in the secondary recording medium.

摘要： An arithmetic unit and an arithmetic method that output no information necessary for decryption or encryption to the outside and can perform a self-protecting function when an illegal attack is made. A command monitoring part (44) monitors input command sequences. In a first sequence, a process key in a first stage is calculated from a hardware key (Khd) and is then written to a key storing part (47). In each of the following sequences, a process key in a next stage is calculated from a process key stored in the key storing part (47). When commands of predetermined contents are inputted in predetermined order, a content key is calculated and then written to the key storing part (47). Encrypted data is decrypted with the content key, and the result is outputted from data output means (63). When an illegal attack is made, initialization is performed by selecting fixed value data (Kf) as key data (Ksl) and selecting fixed value data (Df) as input data (Ein).

摘要： A data transfer system provided by the present invention is capable of executing proper management of content transfers with a high degree of efficiency. In a data transfer apparatus employing a primary recording medium, rights to transfer contents stored in a primary recording medium are managed, and transfer rights of contents already transferred to a secondary recording medium employed in a data-recording apparatus are managed by using a generated table for associating first content identifiers each generated by the data transfer apparatus for a content stored in the primary recording medium with a second content identifier received from the data-recording apparatus and generated by the data-recording apparatus for the content, which has already been transferred to the data-recording apparatus. Thus, even if the secondary recording medium cannot be used for recording a second content identifier (or a content ID), a content ID (a second content identifier) generated for a content can be used for identifying the content by associating the content ID (the second content identifier) with a content ID (a first content identifier) stored in the primary recording medium.

摘要： Disclosed is a method for causing either encrypted first content data or unencrypted second content data, to be selectively recorded to a storage medium in a data recording apparatus. When the data recording apparatus is to return the encrypted first content data to the data transfer apparatus, the return is inhibited if the data are judged to have been edited. Upon return of the encrypted first content data, a content ID held by the data recording apparatus regarding the first content data is matched against a content ID held by the data transfer apparatus regarding the received data. Where the encrypted first content data are known to have been edited, the content ID matching process is omitted.

摘要： An image pickup apparatus such as a video camera has the capability of automatic white balance control whereby the white balance is quickly adjusted for any object even just after an operator has turned on a power supply. An image pickup element converts an optical image of an object into an electrical image signal. The image signal is applied to a signal processing circuit and separated into a luminance signal and color signals. The separated color signals or the R and B signals are amplified by gain control circuits under the control of the correction signals supplied by a correction signal computing part, and then applied to a color-difference signal forming circuit which in turn produces color-difference signals (R-Y) and (B-Y). An encoder circuit generates a television signal in the standard form from the above color-difference signals and the luminance signal. In this processing, the white balance is adjusted according to a white balance control signal generated on the basis of information about a state of illuminance onto an object picked up last time and stored in a data storing part.

摘要： Disclosed is a key generator, which assures the security of a key by preventing a circuit designer and other persons from readily knowing the value of the key. Random number generator circuits (51, 52, 53 and so on) generate random numbers respectively in accordance with different clocks (CLK1, CLK2, CLK3, and so on). An arithmetic circuit (59) operates on the random numbers generated from the random number generator circuits (51, 52, 53 and so on) to generate an N-bit random number RA as the output from a random number generator (50). This N-bit random number is RA acquired via a key selector (43), and latched into a key register (45) in accordance with an acquisition enable signal EN from a timing monitoring counter (47), which is driven by a clock CLKA other than clocks CLK1, CLK2, CLK3, and so on, to obtain a hardware key, which is a unique secret key.
