  Next, FIG. 6 is a sequence diagram for explaining an outline of an operation for displaying the setting input screen of the information processing device 1 on the display device 2 in accordance with the Miracast standard. First, in step S20, the first display control unit 54 of the information processing apparatus 1 reads the setting input screen data 520 stored in the storage unit 52 and generates setting input screen image data. Next, in step S21, the first display control unit 54 converts (encodes) the setting input screen image data generated in step S1 into a moving image format setting input screen generation signal that can be transmitted according to the Miracast standard. Thus, the setting input screen generation signal is generated.

  In step S22, the first communication control unit 55 and the first communication unit 53 transmit the setting input screen generation signal generated in step S21 to the display device 2. In step S <b> 23, the second communication unit 63 of the display device 2 receives the setting input screen generation signal and sends the received setting input screen generation signal to the second display control unit 64 of the control unit 60. Then, the second display control unit 64 displays the setting input screen on the display screen 2a of the display unit 62 based on the setting input screen generation signal. It is assumed that a button for displaying the setting signal input screen is displayed on the setting input screen.

  In step S24, the user waits for the user to operate a button for displaying the setting signal input screen, and when the second input unit 61 detects that the user has operated this button, the second input unit 61 The detection result is sent to the control unit 60, and the process proceeds to step S25. In step S25, the second display control unit 64 generates a setting signal input screen generation signal, and is superimposed on the setting signal input screen on the display screen 2a of the display unit 62 based on the setting signal input screen generation signal. To display the setting signal input screen. Note that, as shown in step S11 of FIG. 5, since the keyboard connection setting of the display device 2 has already been made, a software keyboard or the like provided in the display device 2 can be used for this setting signal input screen.

  In step S26, in a state where this setting signal input screen is displayed, the user waits for the user to input the setting signal by operating the second input unit 61, and the second input that the user has input the setting signal. If the input part 61 detects, the 2nd input part 61 will send this setting signal to the control part 60, and will transfer to step S27. In step S27, the control unit 60 accepts the setting signal input via the second input unit 61. In step S28, the second communication control unit 65 and the second communication unit 63 are connected to the second input unit. The setting signal input via 61 is transmitted to the information processing apparatus 1. The control unit 50 of the information processing apparatus 1 receives the setting signal via the first communication unit 53, and changes the content of the setting input based on the setting signal as necessary. If the setting input screen permits selection input such as so-called radio buttons and check boxes, the connection setting of the mouse of the display device 2 has already been performed as shown in step S11 of FIG. Therefore, when the user touches a radio button or the like on the setting input screen without displaying the setting signal input screen, the second input unit 61 detects this touch operation, and the second input unit 61 It is also possible to output a setting signal as a selection input signal.

  In step S29, it is determined whether or not the power of the display device 2 is turned off. If the power is not turned off (NO in step S29), the program returns to step S24 and the operations in steps S24 to S29 are repeated. . On the other hand, when the power is turned off (YES in step S29), the setting input is completed in step S30, and the pairing with the information processing apparatus 1 is released. On the other hand, when the power of the display device 2 is turned off, the information processing device 1 cannot receive packets from the display device 2. The control unit 50 of the information processing device 1 determines that the power of the display device 2 is turned off when the packet from the display device 2 does not arrive for a certain time, and completes the setting of the information processing device 1 in step S30. The pairing with the display device 2 is released.

(Effect of screen display system of one embodiment)
As described above in detail, in the screen display system S of the present embodiment, the first display control unit 54 of the information processing apparatus 1 sets input for displaying the setting input screen on the display screen 2a of the display apparatus 2. Since the screen generation signal is generated in at least one of the still image format and the moving image format, the setting of the information processing apparatus is confirmed not only on devices such as PCs that can display based on HTML data but also on various devices. It becomes possible to do. In addition, even devices equipped with browsers that can display HTML data, such as smartphones and tablet terminals, can display without breaking the layout of the setting input screen. Can be confirmed on various devices.

  Further, according to the present embodiment, an operation input screen that is a common UI (User Interface) screen can be displayed on the display screen 2 a of the display device 2 regardless of the display capability or function of the display device 2. Thereby, regardless of the model of the display device 2, a common UI screen can be provided to the user. In particular, since the operation input screen provided by the information processing apparatus 1 has been changed, such as improvement of the function of the information processing apparatus 1 or provision of a new operation input screen, the operation input screen that could be displayed on the display device 2 has been changed. At least a part of the operation input screen that is newly provided, in particular, may not be displayed on the display device 2. However, according to the information processing device 1 of the present embodiment, even if there is a function improvement or the like. The situation where the operation input screen cannot be displayed on the display device 2 can be avoided.

  In addition, in the present embodiment, since the setting input screen generation signal is transmitted to the display device 2 wirelessly, the information is displayed in a state where the degree of freedom in arrangement between the information processing device 1 and the display device 2 is increased. A setting operation for the processing apparatus 1 can be performed. As a result, it is possible to relax restrictions on the place where the setting operation of the information processing apparatus 1 is performed.

  In particular, in the present embodiment, since the operation input screen generation signal is sent to the display device 2 according to the procedure according to the Miracast standard, the smartphone, the tablet terminal or the like having a function of performing screen display according to the Miracast standard is used. Can also display the setting input screen. In recent years, many smartphones and tablet terminals have a function of performing screen display in conformity with the Miracast standard, and there is a great merit that an operation input of the information processing apparatus 1 can be performed using a smartphone or the like originally owned by the user.
