ION UP) button 108A and the position down (PO
(SIONDOWN) button 108B and a list (LIST) button 108C for instructing display of preset contents.

The control microcomputer 112 outputs a tuning signal and a mute signal to the tuner 104,
Performs channel selection control and mute control. Also, the tuner 104
To the control microcomputer 112, a signal indicating the channel selection state (information on whether or not any broadcast can be received) is output. In addition, a font selection signal is output to the character generator 110 to perform character addition control on the reproduced video and the broadcast video, and the position preset information is extracted from the storage device 106. Further, the control microcomputer 112 operates the storage device 10 by pressing the list button 108C as a unique control in this example.
6 is provided with a function of outputting a font selection signal to the character generator 110 based on the preset information from 6 and displaying the video signal on the external monitor device 200.
Although FIG. 1 mainly shows only a configuration for realizing the functions of the present invention, an actual device is provided with a small LCD display unit, other operation keys, and the like also on the main body 100 side. Of course.

Next, a method of selecting a preset position in this embodiment will be described. It is assumed that the FM / AM broadcast receiving apparatus of this example has, for example, 30 positions that can be preset, and is preset as shown in FIG. If the position currently being received is “A1” and the position up button 108A is pressed, the position is increased by one and the state transits to “A2”. However,
When the position down button 108B is pressed, the position is lowered by one and an attempt is made to transition to "C0". However, since there is no preset, the position is lowered by one and the state transits to "C9". By performing similar processing, a transition operation as shown in FIG. 2 is performed.

Next, the procedure for determining the preset position channel selection as described above will be described with reference to the flowchart of FIG. The control microcomputer 112 first reads the preset information from the storage device 106 (S2),
It is determined whether or not the list button 108C has been pressed (S
4). As a result, when the list button 108C is pressed,
The display of the list of preset information on the external monitor device 200 as shown in FIG. 4 is started or ended (S6).
That is, in a NORMAL display state in which a list of preset information is not currently displayed on the external monitor device 200, a list of preset information is displayed by pressing the list button 108C. In this case, the character generator 110 is controlled to transmit the character additional information by serial communication. If a list of preset information is currently displayed on the external monitor 200, the list of preset information is terminated by pressing the list button 108C.

Next, the control microcomputer 112 determines the current position number. (I) is temporarily saved in the internal buffer (J). And the position up button 10
8A and whether the position down button 108B has been pressed (S10, S1).
2) When the position up button 108A is pressed, the processing shifts to position up processing, and the position down button 10A is pressed.
When 8B is pressed, the flow shifts to position down processing. That is, in this example, the external monitor device 200
In addition, a position up process and a position down process are performed irrespective of the presence or absence of the list display of the preset information. The list display of the preset information is merely an auxiliary function. Therefore, position up processing and position down processing can be performed irrespective of the connection state of the external monitor device 200 and the like. In addition, the preset information list display function does not complicate the preset position tuning operation by the position up process or the position down process. The difficulty has been improved.

Next, the position up processing and the position down processing in this embodiment will be described. First,
In the position up processing, the current position number is set.
(I) is incremented by 1 (S14). At this time, if (I) is equal to or more than the preset position number (N) of the main broadcast receiving apparatus (S16), (I) is set to 0 (S18).
Also, if (I) is between 0 and N−1 in S16,
If one round has been made in comparison with the previously saved (J), it is determined that no preset has been made, and the processing exits (S).
20, S22). Further, it is determined whether (I) newly set in S14 or S18 has been preset based on the preset information from the storage device 106, and if it has been preset (S22), the newly set (I) has been set. ) Position No. (I) is determined, and the process proceeds to S34. If no preset has been made, the process proceeds to S14, where (I) is incremented by 1 and the same processing is repeated.

On the other hand, in the position down processing, first, the current position No. (I) is decremented by one (S24). At this time, if (I) is equal to or more than the preset position number (N) of the main broadcast receiving apparatus (S26), (I) is set to N-1 (S28). Further, if (I) is between 0 and N-1 in S26, it is determined that there is no preset when it has made one round, compared with (J) that was previously evacuated, and the process exits. (S30, S32). Also, S3
4 or (I) newly set in S38 is the storage device 1
It is determined from the preset information from step 06 whether or not a preset has been made.
32), the newly set position No. (I).
(I) is determined, and the process proceeds to S34. If no preset has been made, the process proceeds to S24, where (I) is decremented by 1, and the same processing is repeated.

Next, at step S34, the determined position number. In (I), it is determined whether the preset has been performed again. If the preset has been performed, the frequency data is transmitted to the tuner 104 so as to receive the broadcast corresponding to the preset information (S36). If not preset, the mute data is transmitted to the tuner 104 so as not to output the tuner output to the tuner 104 (S38).

Next, in S6 described above, the list button 1
A list display of preset information when 08C is pressed will be described. As shown in FIG. 4, the list button 108C
With one operation, the list display of the preset information (FM / AM TUNER LIST screen display) on the external monitor device 200 is started, and the list display of the preset information is ended by operating the list button 108C again. The list of the preset information is displayed as the preset number. A1 to A
0, a second screen from B1 to B0, and a third screen from C1 to C0, with the operation of the position up button 108A and the position down button 108B described above. The screen scrolls.

In the list display of the preset information, the currently preset information is displayed, and the currently received position number. Is displayed with the cursor. Thus, the user of the broadcast receiving apparatus can assume the next broadcast station, and can check the current preset status at a glance. In the screen shown in FIG. 4, the title of "FM / AM TUNER LIST" is displayed at the first display, and the "MEMORY" which indicates the broadcast currently being received and the preset memory is available in accordance with the preset position tuning operation. FM 80.00 MHz ". Further, in the screen shown in FIG.
Although icons and the like corresponding to setting operations and the like on the broadcast apparatus main body 100 are displayed, they are not directly related to the functions of the present invention, and thus description thereof is omitted.

Although the configuration relating to the functions of the present invention has been mainly described above, the present invention is not limited to the above-described example, and various modifications are possible. For example, in the above-described example, a configuration in which the list display of the preset information is exclusively displayed on the external monitor device 200 has been described. However, it is needless to say that the preset information may be simultaneously displayed on the display unit of the main body 100. Further, in the above example, a function of skipping an empty position when selecting a preset position and a function of selecting an empty position, and a function of preventing occurrence of noise or the like using mute data for the empty position,
Although the configuration has been described in combination with the function of displaying a list of preset information by the external monitor device 200, only one of the functions may be provided.
