Claims35
An operational terminal device comprising:
- a control unit to control display, on a display screen of the terminal device, of at least one operation button to control a display control device external to the terminal device, based on a result of analysis of button information associated with the operation button and received as a display control command from the display control device.
A display control device comprising:
- a control unit to control transmission to an external device, wherein the external device is connectable to the display control device and controls display on a display screen of the external device, of button information associated with at least one operation button as a display control command, wherein a result of analysis of the button information controls display of the operation button on the display screen by the external device.
A method of operating a terminal device comprising:
- controlling, by a processor, display, on a display screen of the terminal device, of at least one operation button to control a display control device external to the terminal device, based on a result of analysis of button information associated with the operation button and received as a display control command from the display control device.
A method of operating a display control device comprising:
- controlling, by a processor, transmission to an external device, wherein the external device is connectable to the display control device and controls display on a display screen of the external device, of button information associated with at least one operation button as a display control command, wherein a result of analysis of the button information controls display of the operation button on the display screen by the external device.
A system comprising:
- an operational terminal device and a display control device external to the terminal device,
- wherein the operational terminal device includes a first control unit to control display, on a display screen of the terminal device, of at least one operation button to control the display control device, based on a result of analysis of button information associated with the operation button and received as a display control command from the display control device, and
- wherein the display control device includes a second control unit to control transmission to the terminal device of the button information.
