  Further, the display control unit 104a causes the display unit 20 to display an image that allows the user to select whether or not to reproduce the sound when the program excluding the detected program from the same program group includes only the sound. That is, when the program excluding the detected program from the same program group is only a radio program or an Internet broadcast audio program, the display control unit 104a allows the user to select whether or not to reproduce the audio program. Is displayed on the display unit 20.

  FIG. 7 is a flowchart showing end detection processing by the program reproducing apparatus according to the second embodiment.

  The end detection process is a process performed when content is played back with video and audio selected by the user in the program playback process of FIG. 4 described in the first embodiment.

  First, whether or not the end detection unit 107 detects the end of one of the program including the video reproduced by the reproduction unit 102 and the program including the audio reproduced by the reproduction unit 102. Is determined (S201).

  When the end of one of the program including the video being reproduced by the reproduction unit 102 and the program including the audio being reproduced by the reproduction unit 102 is detected (S201: Yes), the display control unit 104a determines whether there is a remaining program (S202). That is, when the end detection unit 107 detects the end of the viewing program, the display control unit 104a determines whether or not there is at least sound in the program obtained by removing the detected program from which the end is detected from the same program group. . On the other hand, the display control unit 104a did not detect the end of one of the program including the video reproduced by the reproduction unit 102 and the program including the audio reproduced by the reproduction unit 102. If so (S201: No), step S201 is repeated. That is, the display control unit 104a determines whether or not there is a remaining program (that is, a program in which the detected program is excluded from the same program group) in step S202 until the end detection unit 107 detects the end of the viewing program. Wait to do.

  When it is determined that there is a remaining program (S202: Yes), the display control unit 104a determines whether the remaining program is only a radio program (S203).

  If the display control unit 104a determines that the remaining program is only a radio program (S203: Yes), the display control unit 104a confirms with the user whether or not to continue watching the radio program (S204). Specifically, in this case, the display control unit 104a causes the display unit 20 to display a dialog screen 240 (see FIG. 8) for confirming with the user whether or not to continue watching the radio program. Here, FIG. 8 is an example of a dialog screen displayed on the display unit of the television for confirming with the user whether or not to continue watching the radio program. As shown in FIG. 8, the dialog screen 240 displays a UI (dialog 241) that allows the user to select whether or not to continue watching the radio program. The user can indicate whether he / she wants to continue watching the radio program by performing input for selecting “Yes” or “No” in the dialog 241.

  The display control unit 104a determines whether or not the input received by the input receiving unit 105 indicates that viewing is continued (S205). Specifically, it is determined whether “Yes” or “No” is selected by the user in the dialog 241 of the dialog screen 240.

  When the display control unit 104a determines that the input received by the input reception unit 105 indicates that viewing is to be continued (S205: Yes), the display control unit 104a continues to view the radio program (S206), and detects end. End the process.

  Here, the display control unit 104a determines that there is no remaining program in step S202 (S202: No), or determines that the radio program viewing is not continued in step S205 (S205). : No), a message screen 250 (see FIG. 9) for notifying that all programs are gone is displayed on the display unit 20, and the end detection process is ended. Here, FIG. 9 is an example of a message screen that is displayed on the display unit of the television and notifies that all programs are gone. As shown in FIG. 9, on the message screen 250, a message 251 notifying that all the programs having the same content are finished is displayed.

  If the display control unit 104a determines in step S203 that the remaining program is not a radio program only (S203: No), the display control unit 104a displays a message screen 260 (see FIG. 10A) notifying that the program configuration is changed (see FIG. 10A). S208). Here, FIG. 10A is an example of a message screen that is displayed on the display unit of the television and notifies that the program configuration is changed. In this message screen 260, a message notifying that the viewing program has ended and the same program having the same content as the viewing program is being broadcast on a different channel and that the same program can be confirmed from the service list of the menu are notified. A message 261 including the message is displayed.

  Next, the display control unit 104a determines whether or not an input for displaying a service list by the user has been received by the input receiving unit 105 (S209). When the display control unit 104a determines that there is an input for displaying the service list (S209: Yes), the display control unit 104a displays the option screen 270 (see FIG. 10B) on the display unit 20 as the service list (S210). On the other hand, when it is determined that there is no input for displaying the service list (S209: No), the display control unit 104a repeats step S209. That is, the display control unit 104a waits for the service list to be displayed until an input for displaying the service list is received by the input receiving unit 105. Specifically, if the user performs an input for displaying a menu from an input device such as a remote controller, a menu screen 220 similar to FIG. 5B is displayed. When the service list menu is selected by the user, a UI (option screen 270) for selecting video and audio of options as shown in FIG. 10B is displayed. In this example, the menu screen 220 is displayed once according to the input from the user, and then the option screen 270 is displayed. However, the option screen 270 is directly displayed according to the input from the user. May be.

  FIG. 10B is an example of an option screen displayed on the display unit of the television after the viewing program ends.
