[Flow of processing of TV 1 and mobile phone 2]
A processing flow of the television 1 and the mobile phone 2 according to the present embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart illustrating an example of the processing flow of the television 1 and the mobile phone 2 included in the display system 3.

  As shown in FIG. 10, first, it is assumed that the television 1 is operating in the normal display mode (S1), and the mobile phone 2 is operating in the normal output mode (S11).

  While the television 1 is operating in the normal display mode, the display mode switching unit 24 waits for an instruction to switch to the external input display mode (S2). When there is no input of an instruction to switch to the external input display mode (NO in S2), the display mode switching unit 24 does not switch the display mode, and the television 1 operates in the normal display mode (S1). On the other hand, when an instruction to switch to the external input display mode is input to the television 1 (YES in S2), the display mode switching unit 24 switches the display mode to the external input display mode. The television 1 operates in the external input display mode.

  Further, while the mobile phone 2 is operating in the normal output mode, the output mode switching unit 52 waits for an instruction to switch to the external output mode (S12). When there is no input of an instruction to switch to the external output mode (NO in S12), the output mode switching unit 52 does not switch the output mode, and the mobile phone 2 operates in the normal output mode (S11). On the other hand, when an instruction to switch to the external output mode is input to the mobile phone 2 (YES in S12), the output mode switching unit 52 switches the output mode to the external output mode. The cellular phone 2 operates in the external output mode.

  When the television 1 shifts to the external input display mode and the mobile phone 2 shifts to the external output mode, the television 1 and the mobile phone 2 execute initial setting processing (S3, S4, S13, S14).

  Specifically, when the television 1 shifts to the external input display mode, the key conversion information management unit 28 reads the model information of the television 1 stored in the model information storage unit 31 of the storage unit 11, and sets the communication unit 13. Then, the read model information of the television 1 is transmitted to the mobile phone 2 (S3).

  After the mobile phone 2 shifts to the external output mode, when the key conversion information specifying unit 54 receives the model information of the television 1 from the television 1 via the communication unit 43, the key conversion information specifying unit 54 executes key conversion information specifying processing (S4). . Specifically, the key conversion information specifying unit 54 refers to the key conversion information specifying table stored in the key conversion information specifying table storage unit 62 of the storage unit 41 and associates it with the received model information of the television 1. The specified key conversion information is specified, and the specified key conversion information is read from the key conversion information storage unit 61.

Then, the television 1 shifts to the normal display mode (S9). The television 1 operates in the normal display mode after shifting to the normal display mode (S1).

  In addition, after the mobile phone key information analysis process is executed, the output mode switching unit 52 waits for an instruction to switch to the normal output mode (S17). If the switching instruction to the normal output mode is not input to the mobile phone 2 (NO in S17), the display control unit 51 of the mobile phone 2 generates an image again based on the instruction from the mobile phone control unit 53, and generates the image. The transmitted image is transmitted to the television 1 via the communication unit 43 (S15). On the other hand, when a switching instruction to the normal output mode is input to the mobile phone 2 (YES in S17), the output mode switching unit 52 switches the display mode to the normal output mode. Then, the mobile phone 2 shifts to the normal output mode (S18). The mobile phone 2 operates in the normal output mode after shifting to the normal output mode (S11).

  In S9, the television 1 returns to the normal display mode, and after the mobile phone 2 returns to the normal output mode in S18, the television 1 again shifts to the external input display mode, and the mobile phone 2 shifts to the external output mode. In this case, the television 1 and the mobile phone 2 do not have to execute the initial setting process. That is, in this case, the television 1 may not execute the processes of S3 and S4, and the mobile phone 2 may not execute the processes of S13 and S14.

[Flow of TV key information analysis processing and mobile phone key information analysis processing]
Next, the flow of the TV key information analysis process of S7 shown in FIG. 10 and the mobile phone key information analysis process of S16 will be described with reference to FIG.
