Then, when this transition is completed, the transition is sequentially made from the “01” channel of the BSD broadcast system to the “12” channel direction. Furthermore, when the transition in the BSD broadcast system is completed, the transition is made sequentially from the “01” channel of the 110CS broadcast system to the “70” channel direction. Thus, the broadcast station is selected by cyclically changing the channel in the up direction.

  On the other hand, when the down side is pressed, on the contrary, the “01” channel of the terrestrial D broadcasting system sequentially changes in the down direction from “10”, “09”,. When this transition is completed, a broadcast station is selected by cyclically shifting from the “01” channel to the down direction in order of the BSD broadcast system and then the 110CS broadcast system. This transition is performed by counting up / counting down based on the depression of the channel up / down button 207 by the counter of the channel selection processing unit 144 described above.

  Information output by pressing the preference button 205, the number selection button 206 of "01" to "12" and the channel up / down button 207 functions as designation information.

  As described above, in the present embodiment, the up / down button map storage unit 126 stores information on a plurality of broadcasting stations of a plurality of different broadcasting systems. Based on the designation from the channel up / down button 207, a plurality of broadcasting stations of a plurality of different broadcasting systems are shifted in the up direction or the down direction to select a broadcasting station. As a result, it is possible to sequentially select broadcast stations of different broadcasting systems simply by pressing the channel up / down button. Once the preference selection button is pressed, broadcast stations of different broadcasting systems can be directly selected by simply pressing the channel up / down button. Therefore, the user can quickly select a desired channel. Furthermore, even when changing the station from the currently selected broadcasting station to a broadcasting station of a different broadcasting system, the channel selection can be quickly changed.

The volume up / down button 208 is a selection button for adjusting the volume. In the volume up / down button 208, a transition is made sequentially in the direction of increasing the volume when the Up side is pressed and in the direction of decreasing the volume when the Down side is pressed.

Then, it is determined whether the assigned station 1 corresponds to one of the assigned assignments 1 to 3 (steps S21, S25, and S28).

  In the present embodiment, a broadcast station having an assignment different from the assignment corresponding to the currently selected broadcast station is selected. That is, when the currently selected broadcast station corresponds to the read assignment 3, it is determined whether or not the read assignment 1 is registered (step S22). Channel 1 is selected (step S23). Then, the predetermined broadcasting system of the selected assignment 1 is read as the last broadcasting system, and the broadcasting station of this predetermined broadcasting system is read as the last channel (step S24).

  If the currently selected broadcast station corresponds to the read assignment 1, it is determined whether or not the read assignment 2 is registered (step S26). If the assignment 2 is registered, this assignment 2 is determined. Is selected (step S27). Then, the predetermined broadcasting system of the selected assignment 2 is read as the last broadcasting system, and the broadcasting station of this predetermined broadcasting system is read as the last channel (step S24).

  If the currently selected broadcast station corresponds to the read assignment 2, it is determined whether or not the read assignment 3 is registered (step S29). If the assignment 3 is registered, this assignment 3 is determined. Is selected (step S30). Then, the predetermined broadcasting system of the selected assignment 3 is read as the last broadcasting system, and the broadcasting station of this predetermined broadcasting system is read as the last channel (step S24).

  When the currently selected broadcast station does not correspond to any of the assigned assignments 1 to 3 (C), it is determined whether or not the broadcast station is registered in any of the assigned assignments 1 to 3 ( Steps S22, S26, S29).

  Here, if there is a broadcast station registration in the read assignment 1, the assignment 1 is selected (step S23). Then, the predetermined broadcasting system of the selected assignment 1 is read as the last broadcasting system, and the broadcasting station of this predetermined broadcasting system is read as the last channel (step S24).

  If there is a broadcast station registration in the read assignment 2, this assignment 2 is selected (step S27). Then, the predetermined broadcasting system of the selected assignment 2 is read as the last broadcasting system, and the broadcasting station of this predetermined broadcasting system is read as the last channel (step S24).

  If there is a broadcast station registration in the assigned assignment 3, the assignment 3 is selected (step S30). Then, the predetermined broadcasting system of the selected assignment 3 is read as the last broadcasting system, and the broadcasting station of this predetermined broadcasting system is read as the last channel (step S24).

  In addition, when there is no broadcast station registration in the read assignments 1 to 3, a notification that the channel is not registered in the numeric button map storage unit 125, for example, a display notification on the monitor or a voice notification from the speaker 111 is performed. (Step S31), the process returns to Step S15 in FIG. 7 to wait for the next button operation.

Next, a case where the same number selection button 206 is continuously pressed will be described.
First, assignments 1 to 3 corresponding to the numbers of the number selection button 206 are read (step S20), and whether or not the currently selected broadcast station corresponds to the read assignments 1 to 3 is compared (steps S21 and S25). , S28). Here, if the current channel selection coincides with the assignment 3, the assignment 1 is selected (step S23), and the broadcasting station of the assignment 1 is stored as the last channel (step S24). Next, when the same number selection button 206 is continuously pressed, assignments 1 to 3 corresponding to the numbers of the number selection button 206 are similarly read (step S20), and the assignment 1 read by the currently selected broadcast station is read. Are compared with each other (steps S21, S25, S28). Here, since the broadcasting station of assignment 1 is stored as the last channel, the current tuning is matched with assignment 1 in step S25, and the broadcasting station of assignment 2 is selected (step S27). Similarly, when the same number selection button 206 is pressed again, the broadcasting station of assignment 3 can be selected in step S30.

  As described above, in this embodiment, each broadcasting station of a different broadcasting system is assigned to each number selection button, and each time the same number selection button is pressed, the broadcasting station of this assigned broadcasting system is directly selected. . As a result, it is possible to select only broadcast stations of arbitrarily assigned broadcasting systems, and to select the broadcasting stations that you want to watch compared to the case of selecting all the broadcasting stations of all registered broadcasting systems sequentially as in the past. You can tune in quickly.

FIG. 9 is a subflow diagram showing an example of an operation procedure of the broadcast receiving apparatus 100 using the up / down buttons.
In FIG. 9, when the channel up / down button 207 is pressed (step S17), the broadcast receiving apparatus 100 determines whether there is a channel that can be selected within the currently selected broadcast system. (Step S41)

  If there is no channel that can be selected in the currently selected broadcasting system, the initial value n for selecting the tuner is set to “0” (step S42), and the channel up / down button 207 is pressed in ascending order. Alternatively, the broadcasting method is selected in the descending order (step S43). Next, it is determined whether or not there is a channel (broadcast station) setting (broadcast station not skipped shown in FIG. 5) in the broadcast system of the selected next assignment (step S44).

  If there is no channel (broadcast station) setting (broadcast station not skipped) in the broadcast system of the selected next assignment, “1” is added to the initial value n for selecting a tuner (step S45), and this n is It is determined whether or not it is larger than (the number of tuners-1) (step S46). Here, when n is not larger than 2, that is, when channel settings are not determined for all (three in this embodiment) tuners shown in FIG. 5, the process returns to step S43. The broadcasting system is selected in the ascending or descending direction when the channel up / down button 207 is pressed.

  When n is larger than 2, that is, when channel setting is determined for all the broadcasting systems shown in FIG. 5 (three tuners in this embodiment), channel setting is determined. All the tuners are finished and it is determined that no channel that can be selected is registered for all broadcasting systems, and notification to that effect, for example, display notification on the monitor 110 or audio notification from the speaker 111 is made (step). S47), the process returns to step S15 in FIG. 7 to wait for the next button operation.

  If a channel that can be selected is registered in the currently selected broadcasting system in step S41, or if there is a channel setting in the selected broadcasting system in step S44, a channel up / down button is displayed. It is determined whether there is a broadcasting station that can be selected in the ascending or descending direction in which 207 is pressed (step S48).

If a broadcast station that can be selected in the ascending or descending direction is not registered, the broadcasting system is further selected in the ascending or descending direction when the channel up / down button 207 is pressed (step S49). It is determined whether a channel that can be selected in the descending direction is registered (step S50).
If no broadcasting station that can be selected in the ascending or descending direction is registered, the process returns to step S49 to further select the broadcasting system in the ascending or descending direction when the channel up / down button 207 is pressed. Then, search for a broadcasting station that can be selected for the broadcasting system of the next assignment.

  In addition, when a broadcasting station that can be selected is registered in the broadcasting system of the next assignment in the ascending or descending direction in which the channel up / down button 207 is pressed in step S48, or in the ascending or descending direction in step S50. If a broadcast station that can be selected for the adjacent broadcast system is registered, the broadcast station is selected (step S541).
