摘要： The problem to be solved is that once copyright claimed AV data is passed to application software, the application software can freely process the AV data for recording, etc., defeating the purpose of copyright protection. The invention provides a computer which comprises a system section 12 and an application software section 13, and which takes in copyright claimed, encrypted data via a digital interface 1 for processing therein, wherein the system section 12 judges that the application software section 13 is legitimate application software for the protection of copyright, and if the application software is a legitimate one, the system section 12 passes a key for the encrypted data to the application software section 13.

摘要： A virtual RAM read address generating circuit (41) generates a virtual address on the basis of an output signal of a crystal oscillation circuit (36). A phase comparison circuit (39) which performs phase comparison with a write address, and a spindle control circuit (3) which controls rotation of a disk with reference to outputs of a frequency comparison circuit (38) and the phase comparison circuit (39) are disposed. Therefore, a phase error can be fed back to a spindle motor, thereby preventing linear velocity deviation from occurring in a steady state. By using the thus configured reproducing device, the reproduction quality in the case where a disk wherein recording was performed by the CLV system is reproduced by the variable linear velocity reproduction system is ensured, and both high-speed access and low power consumption are realized.

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： A video/audio processing device, such as a DVD recorder, includes a controller for controlling a state of power-on/off. The controller has a first standby mode and a second standby mode having power consumption larger than that of the first standby mode in a power-off state of the video/audio processing device. The first standby mode is a mode for maintaining a power of the video/audio processing device in the “off” state. The second standby mode is a mode for maintaining the power of the video/audio processing device in an apparent “off” state. The controller switches between the first standby mode and the second standby mode in conjunction with a state of power-on/off of external equipment such as television.
