摘要： A copy control apparatus is provided in one-to-one correspondence with a car navigation system. Connection of the copy control apparatus with an information processing apparatus such as a PC enables to transmit content only from the information processing apparatus to which the copy control apparatus is connected to the car navigation system. With this configuration, the copy control apparatus stores a device key used to encrypt the content, and encrypts the device key with another encryption key to transmit the encrypted device key to the information processing apparatus. The information processing apparatus encrypts a copy of the content by use of the received device key, and then sends the encrypted copy to a content receiving apparatus. The content receiving apparatus decrypts the received copy of the content by use of a stored device key, and then stores the decrypted copy of the content in a storage unit.

摘要： A license management device receives a license issued by a license issuing device. The license management device transmits the received license to a navigation system for receiving the license, and stores the received license in a memory device. When the license to be acquired cannot be acquired, the navigation system requests the license issuing device to send the license. The license management device reads the license from the memory device, and transmits the license to the navigation system.

摘要： A drive apparatus for driving an optical system of a camera in directions along an optical axis of the optical system through an electric motor. The drive apparatus is equipped with a manual ring provided in a housing of the optical system so as to be manually rotatable about the optical axis of the optical system. The manual ring is fixedly secured to a rotatable plate having a plurality of tooth portions. Also included in the drive apparatus is a rotation detector arranged to be associated with the plurality of tooth portions of the rotatable plate so as to detect the rotation of the manual ring to output a detection signal indicative of the rotation information of the manual ring. A control section is responsive to the detection signal from the rotation detector so as to output a control signal to the electric motor so that the optical system is driven at a speed corresponding to the frequency of the detection signal therefrom. This arrangement allows high-accurate position control of the optical system of the camera at a speed proportional to the rotational speed of the manual ring.
