10. The mobile device of claim 1 , wherein the button information associated with the at least one operation button received by the mobile device includes information to control display on the display screen of the mobile device such that, when the at least one operation button is displayed, display on another display screen is controlled to display contents associated with the at least one operation button without information corresponding to the at least one operation button.
11. The mobile device of claim 1 , wherein the button information associated with the at least one operation button received by the mobile device includes information to control display on the display screen of the mobile device of the at least one operation button to reflect a predetermined broadcast standard.
12. The mobile device of claim 1 , wherein the button information associated with the at least one operation button received by the mobile device includes information to control display on the display screen of the mobile device of the at least one operation button to reflect only operable operation buttons.
13. The mobile device of claim 1 , wherein the control unit is configured to control display on the display screen of the mobile device of a label based on the button information associated with the at least one operation button received by the mobile device.
14. The mobile device of claim 1 further comprising:
a touch panel superimposed on the display screen of the mobile device.
15. The mobile device of claim 1 , wherein the control unit is configured to control display on the display screen of the mobile device of indicia representing a next chapter and a previous chapter of content based on the button information associated with the at least one operation button received by the mobile device.
16. The mobile device of claim 15 , wherein the content is from the electronic device or the different type of external device.
17. The mobile device of claim 1 , wherein the control unit is configured to control display on the display screen of the mobile device to indicate an operating state of the electronic device or the different type of external device.
18. The mobile device of claim 1 , wherein the control unit is configured to control display on the display screen of the mobile device when the button information associated with the at least one operation button received by the mobile device indicates volume of the electronic device is changed.
19. The mobile device of claim 1 ,
wherein the at least one operation button is displayed after the mobile device is determined to be in remote control mode.
20. A method of operating a mobile device, the method comprising:
controlling, by a processor, display, on a display screen of the mobile device, of at least one operation button to control an electronic device external to the mobile device, in accordance with analysis by the processor of a display control command indicated in button information associated with the at least one operation button and received by the mobile device,
wherein the at least one operation button is displayed after said electronic device is connected, directly or indirectly, to said mobile device,
wherein at least one different operation button is displayed if a different type of external device is connected, directly or indirectly, to said mobile device, and
wherein a remote control signal is transmitted wirelessly by the mobile device when said at least one operation button is activated.
21. A system comprising:
a mobile device and an electronic device external to the mobile device,
wherein the mobile device includes a first control unit configured to control display, on a display screen of the mobile device, of at least one operation button to control the electronic device, in accordance with analysis by the first control unit of a display control command indicated in button information associated with the at least one operation button and received by the mobile device,
wherein the at least one operation button is displayed after said electronic device is connected, directly or indirectly, to said mobile device,
wherein at least one different operation button is displayed if a different type of external device is connected, directly or indirectly, to said mobile device,
