Abstract

Abstract The present invention provides electronic equipment which requires no space for installation, the degree of freedom in relation to the extension of a function of which is large and which enables the reduction of the cost. The present invention saves space in the extension of a function by providing an expanding slot for installing expanded equipment to the body of a video display terminal. In a state in which a scan converter is connected to the body of the video display terminal, a serial bus 30c which is an internal bus of the video display terminal and a serial bus 50 which is an internal bus of the scan converter are connected and the internal bus of the video display terminal seems to be extended to an external device. Serial buses 30a, 30b and 30c which are the internal bus of the video display terminal can be switched in a bus switch. After the scan converter is connected to the video display terminal, the scan converter controller of the scan converter controls a user interface in place of the main control unit of the video display terminal.
