Abstract: A content selection server according to the present invention includes: a reception unit configured to receive a current location of a vehicle; a storage unit which stores advisory information about one or more objects that exist on one or more roads and require attention on driving; a transmission unit configured to transmit information; and a control unit which can select a content to be played back. The control unit includes a driving concentration level setting unit configured to obtain a driving concentration level (STEP 31) and, based on the obtained driving concentration level, the current location of the vehicle (STEP 31), and the advisory information (STEPS 32 to 33), and selects at least one category of the content to be played back (STEP 34).

Abstract: A pulse signal whose duty ratio differs for selected channels is coupled with the base of a first transistor as a switching transistor. The switching transistor is connected at the collector to a voltage source via a load resistor, and at the emitter to a reference potential point. An inverted pulse signal, which is derived from the collector of the first transistor, is rectified by a rectifying filter including a capacitor, and subsequently is applied to a tuning voltage terminal of an electronic tuner. A DC voltage proportional to an AFT voltage is applied to the base of a second transistor whose collector-emitter major current path is connected between a charge/discharge path of the capacitor and the reference potential point. A current flow through the major current path for a period of time, which differs for selected channels.
