        FIG. 9 to FIG. 14 show the steps of registering the program name in the service list and the steps of the channel selection operation process during viewing in the processing in the portable television broadcast receiver (1) of the present embodiment. When the power is turned on, an initial process (S100) is first executed. Initial processing includes clearing the working memory and initializing each timer. When the initialization is completed, a menu is displayed (S101). A desired menu is selected from the displayed menu (S102). If the selected menu is other than TV viewing (No in S103), the selected function is executed (S104), and when the selected function is completed, the process returns to S101 to display the menu.

        If the selected function is TV viewing (Yes in S103), the tuner (102) is turned on (S105), and the last channel information is acquired (S106). The last channel information is information on the channel (service) selected immediately before, and is held in the NVRAM (109). The presence or absence of information on the last channel is checked. If the last channel information is not held in the NVRAM (109) (No in S107), the first channel (service) information in the service list is acquired (S108). Here, the first channel (service) information is channel (service) information stored as service 1 in FIG. However, the present invention is not limited to the first channel (service) information. Any one channel (service) in the channel (service) information registered in the service list may be acquired.

        However, if the service list is not stored in the RAM (108) or the NVRAM (109) (No in S109), the channel list is scanned to create the service list (S110), and the process returns to S108 again. Here, the service list is a list of information relating to receivable broadcast channels as shown in FIG.

        Next, if the last channel information has been acquired (Yes in S107) or if the information of the first channel (service) in the service list can be acquired (Yes in S109), the tuner (based on the acquired channel (service) information) 102) is selected (S120). However, there may be a case where the acquired channel (service) information is a channel (service) that cannot be received because it is outside the broadcasting area at that time. When it is determined that the channel selection has failed due to the fact that it is out of the broadcasting area or the radio wave condition is not good in this way (No in S121), an error message is displayed (S122).

        Here, whether or not to perform direct channel tuning can be selected in the error display. For example, in the error display, “direct channel selection” or the like is displayed, and the selection is made with soft keys (1071) and (1072) (“YES” and “NO” are arranged on the soft keys). Here, when direct channel selection is selected, in the case of terrestrial digital television broadcasting, a three-digit channel number that can designate each broadcasting service can be input using the numeric key (1076) (Yes in S123), and the process goes to S120 Return.

        On the other hand, if direct channel selection is not selected (No in S123), a channel scan selection screen is displayed on the display device (106). Specifically, a message such as “Do you want to scan the channel” is displayed, and the selection is made with the soft keys (1071) and (1072) (“YES” and “NO” are arranged on the soft keys). If the channel scan is selected (Yes in S124), the process returns to S110. If the channel scan is not selected (No in S124), the process returns to S101 and the menu is displayed.

        On the other hand, if it can be determined that the channel selection is successful (Yes in S121), the selected channel (service) information is stored in the NVRAM (109) as the last channel (S125). Subsequently, the television image of the selected channel (service) is displayed on the display device (106) as shown in FIG. 7 (S126).

        Here, a key input waiting state is entered (S127). If any key input device (107) is operated, if it is not a menu key (No in S128), the function selected by the key input device (107) is executed (S129). When the execution of the selected function is completed, the process returns to S127 and again waits for key input. Here, the operations other than the menu key include, for example, increase / decrease in volume, BML browser processing, and the like.

        On the other hand, if the operated key is a menu key (Yes in S128), a menu screen is displayed in the display area 1062 of the display device (106) (S130). Here, the menu key is arranged on the function key (1075) in the key input device (107), but the present invention is not limited to this.

        Next, using the key input device (107), one function is selected from the displayed menu (S131). If the selected function is a program name display (Yes in S132), the program name of the program being viewed is displayed in a pop-up window as shown in FIG. 7 (S140). Here, the program name may be acquired from program information (EIT) acquired from a broadcast wave, or may be based on program information downloaded from a server on the Internet in advance.

Furthermore, when registration in the service list is selected by operating the key input device (107) (Yes in S141), registration confirmation in the service list is performed as shown in FIG. 8 (S142). Here, as a method for selecting registration in the service list, in this embodiment, the selection key is arranged on the function key (1075), but it is not necessarily limited to this. For example, it may be arranged in any of the soft keys (1071) (1072) (1073), by operating the menu key from the display state of FIG. 7, to display the menu, the service in the menu An item for selecting registration in the list may be arranged.

        Next, if registration to the service list is permitted (Yes in S143), specifically, when Yes is selected using the cross key (1074) in the display state of FIG. 8, as shown in FIG. In the service list, the program name pop-up displayed for the service being viewed is registered (S144).

        As described above, when the registration of the program name in the service list is completed, the pop-up window of the program name is deleted on the display device (106) (S145).

        In addition, when registration in the service list is not selected in the program name display state (FIG. 7) and registration in the service list is not selected even after a predetermined time (1 minute in this embodiment) elapses, The program name pop-up window is deleted (S145). That is, if registration to the service list is not selected in the program name display state (S140), the first timer is started and the first predetermined time is counted (S147). Here, the first predetermined time is 1 minute, but this time is not limited to this, and the user may change the setting by operating the key input device (107). Until the first timer finishes counting the first predetermined time (No in S148), the program name continues to pop up. When the first predetermined time elapses, a pop-up window for the program name is displayed on the display device (106). Erasing is performed (S145).

        Specifically, when the program name display state is entered (S140), the first timer is not operated until the registration to the service list is selected (No in S141) and the first timer is not operating (No in S146). When the first timer is operating (Yes in S146) or started, the process from S141 to S147 is repeated until the first predetermined time elapses (No in S148), and the first predetermined period elapses (S147). In S148, the display device (106) deletes the program name pop-up window (S145).

        Also, in the registration confirmation in the service list, if registration in the service list is not performed (No in S143), specifically, No is selected using the cross key (1074) in the display state of FIG. In this case, the program name pop-up window is deleted on the display device (106) (S145).

        Here, in the present embodiment, the first timer is a counter provided in the control device (105). However, the first timer is not limited to this, and any type of timer may be used.

        On the other hand, in the menu selection (S131), if the selected function is not a program name display (No in S132), if the selected function is not a channel selection (No in S150), the processing of the selected function is performed. Perform (S151), and return to S101 to display the menu.

        However, if the selected function is channel selection (Yes in S150), the currently valid service list is displayed (S152), and the cursor is displayed on the currently viewed service (S153). If there is a program name registered in the service, the program name is displayed in a pop-up window as shown in FIG. 6 (S154), and a key input waiting state is entered (S155).

        If the input key is a cross key (1074) that is a cursor movement key (cursor movement key in S155), if the operated key is an upward key (Yes in S160), the cursor is moved up by one. It is moved and displayed (S161). However, if the cursor key is already at the top, the cursor is moved to the bottom position for display (S162).

        On the other hand, when the input key is the cross key (1074) that is the cursor movement key (cursor movement key in S155), the operated key is not the up key (No in S160) and is the down key. (Yes in S163), the cursor is moved down by one and displayed (S164). However, if the cursor key is already at the bottom, the cursor is moved to the top position and displayed (S165).

        Next, when the service corresponding to the position where the cursor on the service list has moved is not registered (No in S166), the process returns to S155 to wait for key input. On the other hand, if a service corresponding to the position where the cursor on the service list has moved is registered (Yes in S166), the process returns to S154, and the service list shown in FIG. 4 is registered for that service. The program name is displayed in a pop-up window as shown in FIG.

        Alternatively, when the input key is the cross key (1074) which is a cursor movement key (cursor movement key in S155) and the operated key is neither an up key nor a down key (No in S160, No in S163), this input is ignored, and the process returns to S155 to wait for the key input again.

        On the other hand, if the input key is a clear key (clear key in S155), the menu screen is deleted and the television viewing screen is returned (S170), and the flow returns to S127 to wait for key input. Here, it is assumed that the clear key is arranged on the function key (1075). However, the arrangement of the clear key is not limited to this, and any format may be used.

        Furthermore, when the input key is an OK key (the center part of 1074) (OK key in S155), the service information on which the cursor is displayed is acquired (S171). Specifically, the cursor causes the tuner (102) to select the displayed service (S120).

        In the above embodiment, the program name is pop-up displayed by operating the input key device while watching the program. However, the program name is automatically displayed for a predetermined period (for example, 1 minute) during program watching or after program selection. The program name may be displayed as a pop-up.
