As a video to be acquired, there is a map having a relatively large size that needs to be confirmed.

(Horizontal screen (PinP))
As shown in FIG. 6, the horizontal screen (PinP) displays the smartphone screen 103 on the entire screen of the display screen 101 a of the television receiver 101, the television screen 102 is smaller than the smartphone screen 103, and the smartphone screen 103. Is defined as a two-screen display of PinP (picture-in-picture) that is displayed so as to overlap. Here, the maximum and minimum size of the television screen 102 is normally a size defined when displaying two PinP screens. For example, 1/4 to 1/8 (1/16 to 1/64 in area ratio) with respect to the entire screen.

  On the horizontal screen (PinP), for example, the television screen 102 displays a video reproduced by digital broadcasting / USB-HDD, and the smartphone screen 103 displays a video (map) acquired by a communication method such as HDMI / Miracast.

  Here, the vertical screen shown in FIG. 4 shows a display state when the arrangement direction of the display screen of the smartphone 201 is the vertical direction. The horizontal screen (PoutP) shown in FIG. 5 and the horizontal screen (PinP) shown in FIG. Indicates a display state when the arrangement direction of the display screen of the smartphone 201 is the horizontal direction. This display state transition will be described below. Note that the display state transition is performed by detecting the orientation of the display screen of the smartphone 201 and automatically performing the display state transition regardless of the display state transition of the smartphone 201 and the orientation of the display screen of the smartphone 201. There are state transitions.

(Display state transition (automatic))
When the display state transition is automatically performed, when the orientation of the display screen of the smartphone 201 is detected in the full screen display state of the television screen 102 on the display screen 101a illustrated in FIG. 7A, according to the detected orientation, As shown in FIG. 7B, a two-screen display is performed using a vertical screen or a horizontal screen.

  In this embodiment, in order to change the display state, a “smartphone screen” button for projecting the video displayed on the smartphone 201 on the smartphone 201 is provided on the smartphone 201 side, and this button is pressed. In this state, the image on the smartphone 201 side can be transmitted to the television receiver 101. Furthermore, an application “IP remote controller” for controlling the television receiver 101 is activated from the smartphone 201 side. That is, the orientation of the display screen of the smartphone 201 is detected in a state where the “smartphone screen” button is pressed and the application “IP remote controller” is activated.

  When it is detected that the orientation of the display screen of the smartphone 201 is the vertical direction, the display is switched to the two-screen display of the vertical screen shown in FIG. 7B, and the orientation of the display screen of the smartphone 201 is detected to be the horizontal direction. In this case, the display is switched to the two-screen display of the horizontal screen (PoutP) shown in FIG. In this embodiment, the initial two-screen display state when switching from the one-screen display state to the two-screen display state is a horizontal screen (PoutP).

  Here, after switching from the one-screen display state of the display screen 101a shown in FIG. 7A to the two-screen display state of the display screen 101a shown in FIG. 7B, the two-screen display state is a smartphone. When the direction of the display screen 201 is switched, the screen is switched to the corresponding two-screen display state. For example, when the display screen of the smartphone 201 is switched from the vertical direction to the horizontal direction when the two-screen display state is the vertical screen, the two-screen display mode is switched to the horizontal screen (PoutP). Conversely, when the display screen of the smartphone 201 is switched from the horizontal direction to the vertical direction when the two-screen display state is the horizontal screen (PoutP), the two-screen display mode is switched to the vertical screen.

  In the present embodiment, as described above, when it is detected that the orientation of the display screen of the smartphone 201 is the horizontal direction, the two-screen display state initially set is the horizontal screen (PoutP). By switching the screen display state from the horizontal screen (PoutP) to the horizontal screen (PinP) by operating the tool “PinP”, which is a kind of application, without switching directly from the screen display state to the horizontal screen (PinP). Switch to. In the opposite case, the screen is switched from the horizontal screen (PinP) to the horizontal screen (PoutP) by operating a tool “two screens” which is a kind of application.

  When the orientation of the display screen of the smartphone 201 is switched from the horizontal direction to the vertical direction when the two-screen display state is the horizontal screen (PinP), the two-screen display state is switched to the vertical screen.

  The flow of the transition process of the two-screen display state will be described below with reference to the flowchart shown in FIG. This process is performed by the two-screen control unit 112.

  First, the terminal display arrangement information acquisition unit 121 acquires terminal display arrangement information transmitted from the smartphone 201 (S1).

  Next, the terminal display arrangement state determination unit 122 determines the terminal display arrangement state from the terminal display arrangement information acquired in S1 (S2). Here, it is determined from the terminal display arrangement information whether the arrangement direction of the display screen of the smartphone 201 is the vertical direction or the horizontal direction.

  Subsequently, the two-screen generation processing unit 123 determines in S2 and determines whether the result is that the arrangement direction is vertical (S3). Here, when it is determined that the arrangement direction is vertical, that is, the orientation of the display screen of the smartphone 201 is the vertical direction, the process proceeds to S4, a display signal for vertical screen display is generated, and output to the display 113. In S5, the vertical screen display is maintained until the end of the vertical screen display is determined.

  On the other hand, in S3, when it is determined that the arrangement direction is horizontal, that is, the orientation of the display screen of the smartphone 201 is horizontal, the process proceeds to S6, and a display signal for horizontal screen display is generated and output to the display 113. In S7, the horizontal screen display is maintained until the end of the horizontal screen display is determined.

  Thereafter, it is determined whether or not the two-screen display is completed in the vertical screen display state or the horizontal screen display state (S8). Here, it is determined whether or not the “smart phone screen” button of the smartphone 201 has been pressed. If the “smartphone screen” button is pressed, the two-screen display is terminated.

  On the other hand, if the “smart phone screen” button is not pressed in S8, the process proceeds to S1 again to acquire terminal display arrangement information. That is, until the “smartphone screen” button is pressed, the terminal display arrangement information is continuously acquired, the orientation of the display screen of the smartphone 201 is detected, and the vertical screen display or the horizontal screen display is maintained according to the detection result. The

  The example in which the display state transition is automatically performed has been described above. However, the present invention is not limited to this, and the display state transition may be manually performed by the user. An example of manually changing the display state will be described below.

(Display state transition (manual))
