The object of the present invention is to provide a contents providing system which can give an incentive to audiences to view the broadcast program, by providing contents information from a broadcast station apparatus to a mobile terminal via a television set, and the mobile terminal which can be used in the contents providing system. Electromechanical valves are controlled in a manner to reduce hydrocarbon emissions of an internal combustion engine. Virtualized application power budgeting can distinguish between priority applications and non-priority applications at a granular, virtual machine level and reduce the power consumption to only non-priority applications when there are power consumption conflicts.
