  Next, an example of label setting operation when the connection terminal 19 of the external connection device 4 is inserted and removed from the input terminal 16 will be described with reference to FIG.

  First, it is assumed that the user is viewing a video on the television receiver (step S1).

  Next, the process proceeds to step S2 to check whether or not the connection state of the input terminal has been changed. If it is determined in step S2 that there is no change in the connection state of the input terminal, the process returns to step S1 and continues.

  In step S2, for example, when it is detected that the connection terminal 19 of the external connection device 4 is disconnected from the input terminal 16, the process proceeds to step S3, and the label of the corresponding input 2 in the label setting table stored in the memory 12 is displayed. Update to "--- (Delete label)".

  In step S4, the OSD display in which the portion corresponding to the input 2 is “---” is performed for a predetermined time.

  FIG. 7 shows a label display state in step S1 before the connection terminal 19 of the external connection device 4 is disconnected from the input terminal 16, for example. In this example, in addition to the input terminals 15 and 16, two input terminals not shown in FIG. 1 are provided. First, GAME1 is input 1 corresponding to the input terminal 15, GAME2 is input 2 corresponding to the input terminal 16, and An example in which an HDMI terminal and a DVD are connected to inputs 3 and 4 corresponding to other input terminals is shown. FIG. 8 shows the label display state in step S4 when the connection terminal 19 of the external connection device 4 is subsequently removed from the input terminal 16.

  The label display in FIG. 8 is the same as the label display in FIG. 7, but the display contents of input 1, input 3, and input 4 are not changed, but the connection terminal 19 of the external connection device 4 is removed from the input terminal 16 corresponding to input 2. Therefore, “---” is displayed as the input 2 is not connected. In the prior art, even if the connection terminal 19 of the external device 4 is disconnected from the input terminal 16, the label display menu screen is displayed by the user using the remote controller, and the label display of the input 2 remains "GAME2" unless the setting is changed. However, according to the present embodiment, when it is detected in step S2 that the connection terminal 19 of the external connection device 4 has been removed from the input terminal 16, In step S3, the label setting is automatically updated to display that there is no connection (the label is deleted), and “---” is displayed corresponding to input 2 in step S4.

  When the contents changed in step S4 are OSD-displayed and a predetermined time elapses, the process returns to step S1 and the process is continued.

  Further, in step S2, for example, when it is determined that the connection terminal 19 of the external connection device 4 is connected to the input terminal 16, the process proceeds to step S5, and the label setting menu screen is automatically displayed.

  In FIG. 9, reference numeral 27 denotes an example of a label setting menu screen. In the upper part of the label setting menu screen 27, for example, a comment “A new device has been connected to input 2. Select a label.” Is displayed, and “input 2”, “ “Video 2”, “Video”, “CATV”, “CS”, “DVD”, “Game 2”, “Movie”, “D-VHS”, “DVR”, “HDD”, “User Settings” are displayed. The The user can set a desired label by operating a left / right / up / down movement key on the remote controller, selecting a target label, and pressing the enter key. This label option is merely an example, and other labels can be set, and the number of label options is not limited to this. In addition, a column “user setting” in which the user can arbitrarily input a label is provided so that the user can input a desired label. In this case, it is assumed that “HDD” is selected and set as the input 2.

  When the OSD display item “HDD” is selected and set in step S5, the label corresponding to the input 2 of the label setting table is updated in step S6.

  Next, proceeding to step S7, an OSD display character whose portion corresponding to input 2 is “HDD” is generated as shown in FIG. 10 and is OSD-displayed on the video output unit.

  Conventionally, when a new device is connected by connecting the connection terminal 19 of the external connection device 4 to the input terminal 16, the user operates the remote control to display the label setting menu screen 27 and changes the label of the corresponding input 2 Unless otherwise, the OSD display of input 2 remains “GAME2”, which is inconsistent with what is actually connected. However, according to the present embodiment, when the external device “GAME2” connected to the input terminal 16 is disconnected and a new HDD device is connected, the label setting menu screen 27 that prompts the user to automatically set a label is displayed. If a label is selected and entered according to the label setting menu screen 27, “HDD” is OSD-displayed as input 2 as shown in FIG. Therefore, according to the present embodiment, the label can be surely changed without forgetting to change it.

  In the above embodiment, the OSD display after the label change is displayed for a predetermined time in steps S4 and S7, but this is displayed for confirmation at the time of change. Steps S4 and S7 may be omitted if the OSD is displayed by operating the remote controller separately from the processing flow of FIG. 6 in order to display the OSD at any time. In addition, if the display in steps S4 and S7 is terminated by a remote control operation instead of displaying for a predetermined time, the user can surely confirm.

(Second Embodiment)
Depending on the user, the label may be left at the default value, and the label setting operation may not be particularly desired. FIG. 11 shows a second embodiment of the present invention for dealing with this.
The operation in the present embodiment will be described below with reference to FIG. 11 taking as an example the case where the connection terminal 19 of the external connection device 4 is inserted into and removed from the input terminal 16 corresponding to the input 2.

  First, it is assumed that the user is viewing a video on the television receiver (step S11).

  Next, it progresses to step S12 and it is checked whether the connection state of the input terminal was changed. In step S12, when it is determined that there is no change in the connection state of the input terminal, the process returns to step S11 and continues.

  In step S12, when it is detected that the connection terminal 19 of the external connection device is disconnected from the input terminal 16, the process proceeds to step S13, and the label display of the input 2 corresponding to the extracted input terminal 16 is a default value, for example, “ It is checked whether it is “input 2”. If it is the default value, the process returns to step S11 and continues.

  In step S13, when the label display is not the default value, the process proceeds to step 14, and the OSD confirmation screen 28 for confirming whether or not to delete the label is displayed. For example, as shown in Fig. 12, "Do you want to delete the label of input 2? If you select" No ", the label will remain unchanged. "Is displayed on the OSD, and options such as" Yes "and" No "are displayed below it. The user operates the left / right / up / down movement keys on the remote controller to select “Yes” or “No” and presses the enter key. If “No” is selected, the process returns to step S11 and continues. If “yes” is selected, the process proceeds to step S15.

  In step S15, the label display corresponding to the input 2 of the label setting table is updated to "--- (label deletion)".

  In step S16, the OSD (FIG. 8) in which the portion corresponding to the input 2 is “---” is displayed for a predetermined time. The contents changed in step S16 are OSD-displayed for a predetermined time, and when the predetermined time elapses, the process returns to step S1 and the processing is continued.

  Thus, according to the present embodiment, when it is detected in step S12 that the connection terminal of the external connection device has been removed from the input terminal, it is determined in step S13 whether or not the label is a default value. The original label can be left as it is, or it can be erased and OSD displayed as “---”.

  Furthermore, when it is determined in step S12 that the connection terminal 19 of the external connection device 4 is connected to the input terminal 16, the process proceeds to step S17, and it is checked whether or not there is a corresponding input 2 label.

  If it is determined in step S17 that there is a label (in the case of YES), the process proceeds to step S18.

  In step S18, an OSD confirmation screen 29 for confirming whether or not to change the label, for example, as shown in FIG. 13, the label when "Do you want to change the label of input 2?" The "Is displayed on the OSD, and options such as" Yes "and" No "are displayed below it. The user operates the left / right / up / down movement keys on the remote controller to select “Yes” or “No” and presses the enter key. If “NO” is selected (NO), the process returns to step S11 to continue the process.

  If “YES” is selected in step S18 (in the case of YES), and if it is determined in step S17 that there is no label (in the case of NO), the process proceeds to step S19.

  In step S19, the label setting menu screen 27 is automatically displayed.

  FIG. 9 shows an example of the label setting menu screen 27. In the upper part of the label setting menu screen 27, for example, a comment “A new device has been connected to input 2. Select a label.” Is displayed, and “input 2”, “ “Video 2”, “Video”, “CATV”, “CS”, “DVD”, “Game 2”, “Movie”, “D-VHS”, “DVR”, “HDD”, “User Settings” are displayed. The The user can set a desired label by operating the left / right / up / down movement key on the remote controller, selecting a target label, and pressing the enter key. This label option is an example, and the label can be set to another display, and the number of label options is not limited to this. In addition, a column “user setting” in which the user can arbitrarily input a label is provided so that the user can input a desired label. In this case, it is assumed that “HDD” is selected and set as the input 2.

  When the label “HDD” is selected and set in step S19, the label setting table is updated in step S20.

  Next, proceeding to step S21, an OSD display character whose portion corresponding to input 2 is “HDD” is generated as shown in FIG. 10 and is OSD-displayed on the video output unit.

  As described above, according to the present embodiment, when the connection state of the input terminal changes, there is no forgetting to change the label, the label can be changed reliably, and the user does not want to change the label. In this case, the label can be used as it is, and when the original device is connected as it is simply by connecting / disconnecting the connection terminal of the externally connected device, the label setting change operation can be omitted.
