Abstract

PURPOSE:To reduce the number of switches by providing a switch for displaying receiving frequency with a function indicating refresh sweeping. CONSTITUTION:When it is discriminated that the current display mode is a radio display mode by the 5th step n5, the 10th step n10 discriminates whether a radio selecting switch 8 is pressed or not. When the radio selecting switch 8 is not pressed, an input signal from a reception controller 2 is processed by the 11th step n11 and then the operation is advanced to the 8th step n8, so that the receiving frequench of a radio broadcasting receiver 1 is displayed on a display device 5. When the current display mode is a radio display mode in the 13th step n13, i.e. when a radio mode selecting switch 6b is once depressed and then depressed again, the 15th step n15 discriminates that the operation is trigger for refresh sweeping and informs the discriminated result to the controller 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a receiving controller for controlling a broadcasting receiver with input information from an operation switch as shown in Table (1). A broadcast reception control device that supplies information to a display controller and displays information on a display device.

Conventionally, only one operation switch was required for applying human power to the display controller, and only a single emotion could be input. Therefore, if information on the number of ships could be input manually using a single switch, it would be convenient because the number of switches could be reduced.

The present invention has been made based on the above-mentioned viewpoints,
It is an object of the present invention to provide a broadcast reception control device in which the number of switches is reduced by providing a switch for displaying the reception frequency of a broadcast receiver with an opening for instructing a refresh sweep.

The present invention will be explained in detail below with reference to the drawings.〇 Fig. 1 is a block diagram showing a simplified overall configuration of an embodiment of the invention. The radio broadcast receiver 1 is an electronically tuned radio with a face-locked loop frequency synthesizer,
It is controlled by the controller 2, which is a microcomputer/9).

This reception controller 2 is given a human power of 1'14 by the operation switch 3 from the leather controller 4, and 2
(Display data, that is, frequency data, from the radio broadcast receiver 1 is received from the controller 2 to the display controller 4. The display controller 4 receives the frequency data or other For example, time display data is displayed on the display 5.The display 5 may be a 7-segment display as shown in the figure, or may be a ridge line display.

The operation switches 3 include a display mode selection switch 6, a be R7ft^ seat switch 7, and a number of radio station selection switches 8. The display mode selection switch 6 includes an hour hand mode selection switch 6a and a radio mode selection switch 6.
It consists of b. The display mode selection switch 6 functions to switch the content displayed on the display 5, and once selected, maintains that state. That is, when the time line mode selection switch 6a is pressed, the time bar 1 is displayed on the display 5, and the time length switch 7 can be operated. In this case, the radio channel selection switch 8 does not turn on. When the radio mode selection switch 6b is depressed, the reception frequency of the radio broadcast receiver 1 is displayed on the display 5, and the radio mode selection switch 8 becomes inoperable. In this case, the timing switch 7 does not function. Further, according to the present invention, when the radio mode selection switch 6b is pressed once and then the radio mode selection switch 6b is further pressed, the display controller 4 displays an Iho number for performing a refresh sweep like a regular. Send to receiving controller 2.

Here, an example of the code of the signal transmitted from the display controller 4 to the reception controller 2 is shown in Table 1. Each code consists of 4 bits, for example bQ-b3, and is given to the reception controller 2 as a serial signal or a parallel signal.

(Leaving space below) Table 1 The reception controller 2 controls the radio broadcast receiver l in response to the signals of the codes shown in Table 1 from the display controller 4, and changes the reception status as shown in the example below. The code shown in Table 2 is output to the display controller 4 at the timing of the 21st reversal.

Table 2 In Table 2, bO to b7 indicate each bit, and of the 8 bits, bits b4 to b7 determine the signal type, and b3 to b7 determine the signal type.
The data of each signal is indicated by the bit of bO. That is, for the 1st to 100th received frequencies, frequency data for each is transmitted using bits b3 to bo. Further, the reception channel number and data are also indicated by bits b3 to bO. Furthermore, the symbol WE indicates WRITE ENABLE, and MO indicates M
ONORAL, ST indicates 5TEREO, LO
indicates LOCAL, and DX indicates DELUX.

Signals representing such reception conditions are sequentially output at each timing from T1 to T6 as shown in FIG. In addition,
In Fig. 2, Fig. 2(a), Fig. 2(b), Fig. 2(
c) and Figure 2(d) are 1)7. b6. b5. This is the waveform of each bit of b4, and FIG. 2 (θ) shows the data of bQ-b3.

Referring to FIG. 3, the operating procedure of the display controller 4 will be explained. First, after initial setting is performed in the first step n1, it is determined in the second step n2 whether or not the watch mode selection switch 6a is pressed.
r will be done. When the time nr mode selection switch 6a is pressed, the clock display mode is set in the third step n3, and then the process advances to the fourth step, knob n4, when the 1 mode selection switch 6a is pressed. If no suppression operation is being performed, the process proceeds from the second step n2 to the fourth step n4.

In the fourth step n4, the radio mode selection switch 6b
If the radio mode selection switch 6b is not pressed, the current display mode is determined in the fifth step n5. is the fifth step n
5, proceed to the sixth step n6, and this sixth step n6
It is determined whether the r adjustment switch 7 is pressed or not. When the clock adjustment switch 7 is pressed, after the clock adjustment process is performed in the seventh step n7,
Proceed to the 8th step n8 and watch W! When the adjustment switch 7 is not pressed, the process proceeds from the sixth step n6 to the eighth step n8.

In the eighth step n8, the display data is edited, and in the ninth step n9, display processing is performed. That is, in this case, a clock is displayed on the display 5.

If it is determined in the fifth step 7'n5 that the current display mode is the radio display mode, the tenth step n1
0, it is determined whether the radio channel selection switch 8 is being suppressed. When the radio channel selection switch 8 is not pressed, the input signal from the receiving controller 2 is processed in the 11th step nil, and then the process is processed in the 8th step n8.
The reception frequency of the geo-broadcasting receiver l that is proceeding to the next step is displayed on the display 5. If the radio channel selection switch 8 is pressed in the 10th step nlO, the 12th step nlO
After the signal is encoded and outputted to the receiving controller 2 in step 12, the process proceeds to the 11th step nil, where the receiving frequency is displayed in the same manner as described above.

When the radio mode selection switch 6b is pressed in the fourth step n4, the current display mode is determined in the thirteenth step n13. If the current display mode is the clock display mode in the 13th step n13, the mode is switched to the radio display mode in the 14th step n14, and then the process proceeds to the 11th step nil where the reception frequency is displayed in the same manner as described above. .

If the current display mode or radio display mode is selected in the 13th step n13, that is, if the radio mode selection switch 6b is pressed once and then the radio mode selection switch 6b is pressed again, the 15th step n15 The trigger signal is assumed to be a trigger for refresh sweep in the twelfth step n12.
output to the receiving controller 2.

In this way, the radio mode selection switch 6b is set to 2.
When pressed for the second time or later, the display controller 4 determines that this is a trigger for a refresh sweep, and provides a refresh sweep command signal to the receiving controller 2.

Note that it is also possible to implement the reception controller 2 and the display controller 4 with a single microcomputer.

As mentioned above, according to this Komei, when the switch for displaying the received frequency of the broadcast receiver on the display is operated once and the switch is further operated, a signal for performing the refresh sweep operation is sent from the display controller. Since it is output, it decreases by one, probably because of the operation switch.
