A receiving device that can maintain a desired search condition is provided. There are provided storing means (RAM) for storing a category contained in upper category information of a channel under reception, display means (LCD) for displaying the stored category, instructing means (touch panel) for accepting an instruction of execution of search, searching means (main microcomputer) for searching a channel containing the stored category as the upper or lower category information when the search execution is instructed, tuning means (satellite tuner) for tuning and receiving the searched channel, and control means (main microcomputer) for shifting to a state that the category of the search condition can be input when the search execution is instructed, storing the category concerned as a new search condition into the storing means when the category is input and making the searching means perform search, and making the display means display the category concerned.

Receiving device and control method for receiving device

A display control device comprises a navigation unit for generating route guidance data; a small-sized display unit for displaying information concerning audio-system; and a main unit connected via an interface to the navigation unit and the small-sized display unit with a communication cable, said main unit including: recognizing means for recognizing the connection of the small-sized display unit; and control means for sending out a request for route guidance display to the navigation unit when the recognizing means recognizes the connection of the small-sized display unit, and causing the received route guidance data to be displayed through interruption on the small-sized display unit when the route guidance data generated by the navigation unit is received via the communication cable and the interface.

Display control device and method

A display device is provided with a center unit 10 having a center display unit 12, a slave unit 20 having a slave display unit 21 and a communication line for communicatively connecting the center unit 10 and the slave unit 20. When the center control microcomputer 15 of the center unit 10 detects a predetermined operation through a key operating unit 14, the center control microcomputer 15 and the slave control microcomputer 24 make two of the center display unit 12 and the slave display unit 21 provide a linking display as if these display units operate as one display unit.
