摘要： The present invention provides the following rotation control method for reducing energy consumption of a motor driving a disk. In a constant speed mode, a supply voltage V1 for driving the motor at a constant speed N1 is selected; however, at a lower constant speed N2, a supply voltage V2 lower than V1 is selected. In an acceleration mode for accelerating the motor speed from N2 to N1, a higher supply voltage than V1 is selected just before starting acceleration, and then V1 is selected after the acceleration. In a speed deceleration mode for decelerating the motor speed from N1 to N2, a lower supply voltage than V1 is selected just before starting deceleration, then the supply voltage V2 is selected after the decleration.

摘要： An information reproducing apparatus reproduces one type of information (for example, video information) in synchronous with a plurality of channels of other type of information (for example, audio information) with high copyright protection, and includes a decryption section that decrypts multiplexed stream reproduced from a recording medium, a stream analyzer that analyzes the multiplexed stream which is decrypted to detect first information (video information) contained in the multiplexed stream, a stream conversion section that alters the first information contained in the multiplexed stream which is decrypted, based on an analysis result by the analyzer. The multiplexed stream with altered video information is distributed to second to n-th stream decoders (for example, for achieving a multilingual system).

摘要： In a method of the present invention for controlling stepping motor, the stepping motor driving current is increased or reduced at a fixed inclination in proportion to the time to control the stepping motor effectively, and, a stepping motor driving current pattern is changed by ¼ cycle or more to synchronize the state of excitation between the stepping motor driving means and the stepping motor to control the pick-up very accurately. In addition, the disk apparatus of the present invention, which uses a stepping motor is provided with a pulse rate pattern variable means, a pulse rate change proportion measuring means, and a driving voltage variable means, and when the pulse rate and the pulse rate change proportion are low, the driving voltage amplitude is lowered to reduce surplus torque generation in the stepping motor.

摘要： A digital watermarking apparatus inputs video or audio information and embeds digital watermark in the information, which is capable of preventing digital watermark or set values necessary for digital watermarking operation from being altered. The apparatus includes a verifying section, a decrypting section and a watermarking section. The verifying section verifies encrypted set values using verification data in set values which is added with verification data and encrypted together with verification data, and transmits the verification result to the watermarking section. The verifying section also transmits the encrypted set values which are verified to the decrypting section. The decrypting section decrypts the encrypted set values. The watermarking section embeds digital watermark in the information using the decrypted and verified set values to output it, when a verification result from the verifying section is normal. When the verification result is not normal, the watermarking section does not output the input information to the outside of the apparatus.
