Abstract: A content information acquiring unit acquires content information including a watching-or-listening time period of content that an occupant of a vehicle desires to watch or listen to. A position information acquiring unit acquires position information of the vehicle. A road information acquiring unit acquires road information including information regarding an autonomous driving section and a manual driving section. A route setting unit sets a route in which the vehicle travels through the autonomous driving section in the watching-or-listening time period of the content on the basis of the content information, the position information, and the road information. A notification unit notifies the occupant of the vehicle of the route set by the route setting unit.

Abstract: A data processing unit creates a database for electric field levels of predetermined frequency bands received by a second tuner. An interfering station determination unit determines whether or not there are a first interfering station and a second interfering station to generate intermodulation interference of third-order distortion with respect to a specific receiving station.
