The problem of ensuring safety and work efficiency for the actions of a control target is addressed in an environment in which different types of control systems coexist. A safety control server controls the actions of respective control targets in differing systems and includes an action adjustment unit that, for each control target of differing control systems, outputs to a control target an action adjustment instruction for adjusting the action of that control target when a contention occurs in which the action of that control target deviates from an assumed control result. An action plan adjustment unit, when the adjustment of the action satisfies a prescribed condition, adjusts an action plan indicating an action rule for achieving a function and avoiding a contention in a control target; and a safety rule adjustment unit adjusts a safety rule indicating an action rule for avoiding a contention in the control target.

Previously, users could not be notified when the 3D mode type of a program being received by a digital broadcast receiver was not compatible with the digital broadcast receiver. A reception device is provided with: a reception unit which receives program content including video information and identification information including information for distinguishing whether the program content is 2D program content or 3D program content; and a display control unit which controls the display so as to display whether the aforementioned program content is 2D program content or 3D program content in response to the received aforementioned identification information.

Reception device, display control method, transmission device, and transmission method for program content type

In a digital contents receiver for receiving transmitted digital contents, the digital contents include at least component information indicating an element which constitutes a program of the contents. When the component information indicates that the received digital contents are a 3D component, it is determined whether a display part corresponds to display of the 3D component. If the display part corresponds to display of the 3D component, the received digital contents are displayed in 3D.

In the present invention, control feasibility in a vehicle control system architecture is efficiently determined by performing determination based on control feasibility in a physical element based on a converted parameter when a logical architecture is arranged in a physical architecture. The present invention includes: an arrangement unitthat arranges a logical architecture, which includes a linkage of each of logical functions and an execution time constraint of the linkage, in a physical architecture; a delay time calculation unitthat calculates a processing delay time based on a converted parameter when the logical architectureis arranged in the physical architecture; and a verification unitthat verifies whether a total of the processing delay time satisfies the execution time constraint.

The purpose of the present invention is to provide a system in which the reliability of an automatic driving system can be excellently complemented by a different control system while the automatic driving system is effectively used. The vehicle control device outputs to a drive device one of a first control signal generated on the basis of automatic driving control information, and a second control signal generated on the basis of the relative information between a vehicle and a surrounding object. If an abnormality is detected in the automatic driving control information, the second control signal is output to the drive device in place of the first control signal.
