Abstract

PROBLEM TO BE SOLVED: To properly select, receive, and reproduce only the information that a listener desired to listen to by inhibiting prescribed information from being reproduced by interruption, according to set interrupt inhibition conditions. SOLUTION: When an interrupt inhibition time setting key of a key input circuit 10 is turned on, a microcomputer 4 sets the maximum value (90 minutes), the minimum value (10 minutes), and the intermediate value (50 minutes) of an interruption inhibition time as default values in interrupt inhibition time registers of a memory 7. When an UP key depressed, the microcomputer 4 sets the interrupt inhibition time to +10 (minutes), unless the interruption inhibition time which is already set is the maximum value. With a DOWN key is depressed, the microcomputer 4 sets the interrupt inhibition time to -10 (minutes), unless the set interruption inhibition time is the minimum value. When a desired interrupt inhibition time is set, the operator determines the interrupt inhibition time by operating the setting key.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver having an interrupt reproduction function, and more particularly to an RDS (Radio Data System) receiver having an interrupt reproduction (reception) function such as a news interruption.

[0002]

2. Description of the Related Art In-vehicle audio equipment is required to have a function of easily enjoying music sources on a CD player, an audio cassette deck, etc., in addition to easily obtaining news and traffic information by a radio tuner.

[0003] As a system satisfying such a demand, the RDS system has been proposed by the European Broadcasting Union and put into practical use. This RDS is a PTY (Program Type)
And a TI function (Traffic Information) function.

The PTY function searches (receives) a station broadcasting a desired program based on a PTY code transmitted from a broadcasting station by inputting (selecting) a genre of a program desired to be heard to a tuner. Function. For example, if the reception of the news with the PTY code “01” is set, the tuner detects that the PTY code of the receiving station or the PTY code of another broadcasting station is “01”, and Switch to a broadcast station and output the playback sound.

[0005] Some of these receivers also have an interrupt reproduction function. This interrupt reproduction function is a function of, upon detecting a broadcast including the set PTY code, interrupting the current processing and reproducing / receiving the broadcast radio wave. For example, if the PTY code to be subjected to the interrupt reproduction is set to “01” indicating the news, when the news broadcast is started at any of the broadcasting stations, even if other media are being reproduced, the news broadcast is performed. You can listen automatically.

[0006] The TI function is a function that allows a driver to hear traffic information. When this feature is turned on,
The tuner selects a broadcasting station broadcasting traffic information, switches to the broadcasting station, and outputs a reproduced sound. This TI function can also perform interrupt reproduction.

[0007]

In the RDS receiver having such a function, for example, when the interrupt reproduction function of the news is turned on, even if the news is frequently broadcast, the news is broadcast. Each time it is detected that the TPY code is "01", an interruption occurs and the user must listen to a news broadcast.

Therefore, even if the user wants to listen only to the news broadcast originally desired by the user, for example, 7:00, 8:00, 9:00,.
I had to listen to news broadcast on the minute, 8:30, 9:30, etc. Further, in order not to listen to a news broadcast, it is necessary to temporarily turn off the news receiving function, and to listen to the next news, the news receiving function must be turned on again.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and in a receiver having an interrupt reproduction function, such as an RDS receiver, it is possible to appropriately select only information that the user originally wants to listen to and receive / receive the information.
It is an object of the present invention to provide a receiver capable of reproducing. Also,
An object of the present invention is to provide an easy-to-use receiver.

[0010]

In order to achieve the above object, an RDS receiver according to a first aspect of the present invention transmits predetermined information from a broadcasting station when reproducing a program of an arbitrary medium. R having a function of detecting that it is being broadcast and interrupting and reproducing the predetermined information from the broadcast station
The DS receiver includes a prohibition condition setting means for setting an interrupt prohibition condition, and a prohibition means for prohibiting an interrupt reproduction of the predetermined information according to the interrupt prohibition condition set by the prohibition condition setting means. It is characterized by doing.

According to this configuration, interrupt reproduction (interrupt reception) is prohibited according to the interrupt prohibition condition. Therefore, even when interrupt reproduction is frequently performed under normal circumstances, it is possible to appropriately set the interrupt prohibition condition and reproduce and listen to only the information originally required.

[0012] The prohibition condition setting means includes, for example, means for setting an interrupt prohibition time, and the prohibition means, for example, from interrupt reproduction of the predetermined information to elapse of the interrupt prohibition time. Meanwhile, interrupt reproduction of the predetermined information is prohibited.

[0013] The RDS receiver includes, for example, a PTY code register for storing a PTY code corresponding to the predetermined information, media reproducing means for reproducing a program of the arbitrary medium, Detecting means for detecting a PTY code indicating a broadcast of the specific information contained therein; and detecting the PTY code which is the same as the PTY code stored in the PTY code register. Means for stopping the reproduction of the predetermined information and reproducing the predetermined information, wherein the prohibition means sets the PTY indicating that the predetermined information is being broadcast in accordance with the interrupt prohibition condition.
Even when the code is detected, the reproduction of the media reproducing means is continued, and the reproduction of the predetermined information is prohibited.

The predetermined information is news information, for example. In this case, the RDS receiver includes, for example, a media reproducing unit that reproduces the program of the arbitrary medium such as a CD, and PTY data “01” indicating the broadcast of the news information included in the transmission signal from the broadcast station. When the detecting means detects the PTY data "01" indicating that the news information is being broadcast, the reproducing of the media reproducing means is stopped and the news information is reproduced. And a prohibition means, wherein when the detection means detects PTY data “01” indicating that the news information is being broadcast in accordance with the interrupt prohibition condition, The reproduction is continued, and the reproduction of the news information is prohibited.

The predetermined information is, for example, traffic information.
In this case, the RDS receiver includes, for example, a media reproducing unit that reproduces a program of the arbitrary media, and a detecting unit that detects a TA code indicating a broadcast of the traffic information included in a transmission signal from the broadcast station. Means for stopping playback of the media playback means and playing back the traffic information when the detection means detects a TA code indicating that the traffic information is being broadcast. For example, even when the detecting means detects a TA code indicating that the traffic information is being broadcast, according to the interrupt prohibition condition, the reproduction of the media reproducing means is continued, and the reproduction of the traffic information is performed. Ban.

Further, a receiver according to a second aspect of the present invention includes: a receiving unit for receiving a broadcast wave; a detecting unit for detecting a predetermined signal from the broadcast wave received by the receiving unit; A demodulating means for reproducing a signal obtained by demodulating the broadcast wave received by the receiving means in response to detection of the predetermined signal by the detecting means; and for prohibiting reproduction of the demodulated signal by the demodulating means. And a demodulation control unit for prohibiting demodulation by the demodulation unit and canceling the prohibition according to the prohibition condition set by the prohibition setting unit.

According to this configuration, in a normal state, if the detection means detects the predetermined signal in a broadcast wave, the signal demodulated by the demodulation means is reproduced. However, when the prohibition condition set by the prohibition setting unit is met, reproduction of the signal demodulated by the demodulation unit is prohibited. Therefore, by setting appropriate prohibition conditions by the prohibition setting means, only necessary information can be reproduced.

The prohibition setting means includes, for example, means for setting a prohibition time as a prohibition condition. In this case, the demodulation control unit prohibits the reproduction by the demodulation unit until the prohibition time elapses from the previous reproduction by the demodulation unit.

Media reproducing means for reproducing a program recorded on an arbitrary medium such as a CD is provided, and the demodulating means stops the reproduction by the media reproducing means in response to the detection of the detecting means, and It may be configured to reproduce a demodulated signal of the signal. In this case, the demodulation control means prohibits the reproduction means from stopping reproduction in accordance with the prohibition condition. With such a configuration,
For example, during the period in which the prohibition condition is satisfied, the program reproduced by the media reproducing means is continuously reproduced without being interrupted by interruption reproduction by detection of a predetermined signal, and it becomes possible to enjoy music and the like.

The broadcast wave is an FM signal having RDS data including a PTY code indicating the type of information being transmitted. In this case, for example, the demodulation means reproduces a demodulated signal of a broadcast radio wave when the detection means detects a predetermined PTY code which is the predetermined signal, and the demodulation control means according to the prohibition condition. Even when the detection means detects a predetermined PTY code, the reproduction of the demodulated signal of the broadcast wave is prohibited.

Further, for example, the broadcast wave is an FM signal including RDS data, and the predetermined signal includes a TA code indicating transmission of traffic information. In this case, the demodulation means demodulates and outputs the broadcast radio wave when the detection means detects that the predetermined TA code is set, and the demodulation control means operates according to the prohibition condition. ,
Even when the detecting means detects that a predetermined TA code is set, reproduction of the demodulated signal of the broadcast wave is prohibited.

The timer 11 counts the current time. As the timer 11, an internal timer of the microcomputer 4 may be used.

The media player 21 is a CD player,
It reproduces a program recorded on an arbitrary medium including an audio cassette deck and outputs an audio signal. The switching circuit 22 selects and amplifies one of the audio signals supplied from the muting circuit 3 and the media player 21, supplies the amplified signal to the speaker 23, and reproduces the signal.

The microcomputer 4 is composed of a microprocessor or the like, and controls the operation of the entire RDS receiver using a work area according to a program stored in a program area of the memory 7. For example, the microcomputer 4 takes in an input from the key input circuit 10, performs various settings, and sets the P in the PLL receiving circuit 2.
The tuning frequency of the LL circuit is changed, the receiving station is changed, the receiving frequency is displayed on the frequency display 8, and the receiving station name and the like are displayed as P.
It is displayed on the S display 9. If the received electric field strength is below a certain level based on the detection signal supplied from the reception sensitivity detection circuit 6, the microcomputer 4 sets the receiving station to another station broadcasting the same contents in the same area. Change to

The other characteristic operations of the microcomputer 4 will be described in detail below together with the operation of the RDS receiver.

Next, the operation of the RDS receiver having the above configuration will be described.
(1) PTY mode and reception genre setting processing, (2) interrupt reproduction mode setting processing, (3) interrupt prohibition time setting processing, and (4) interrupt reproduction processing in this order with reference to FIGS. explain.

(1) PTY mode and reception genre setting processing The microcomputer 4 constantly monitors whether or not the key input circuit 10 is operated, and when the PTY key is pressed to set the PTY reception mode. This operation is detected, and the processing shown in FIG. 4 is started. First, the microcomputer 4 sets "PTY mode" in the mode register of the memory 7, and sets "01" as a default in the PTY code register (step S1).

Next, the reception genre corresponding to the PTY code set in the PTY code register is displayed on the display unit (step S2). FIG. 5 shows the relationship between the PTY code and the reception genre. The genre corresponding to the PTY code "01" is "news", and at this stage, "news" is displayed as the received genre.

In this state, when a predetermined preset key is operated, the microcomputer 4
Detects the key operation in step S3, and sets a PTY code corresponding to the operated preset key in the PTY code register (step S4). Next, the reception genre corresponding to the set PTY code is displayed on the display unit (step S2). FIG. 6A shows an example of the relationship between the preset key and the displayed genre.

When the FF key or the REW key is operated, the microcomputer 4 detects this key operation in step S5, and sequentially updates the PTY code set in the PTY code register (step S6). .
Next, the reception genre corresponding to the set PTY code is displayed on the display unit (step S2). Therefore, the displayed reception genre is sequentially updated in the forward direction or the reverse direction as shown in FIG.

When the UP or DOWN key is operated while the received genre is displayed, the microcomputer 4 detects this key operation in step S7, and ends the processing. Therefore, the genre displayed when the UP or DOWN key is operated becomes the reception genre.

Thereafter, the microcomputer 4 sets the PL
The tuning frequency of the L circuit is continuously changed to change the reception frequency.
A search is made for a broadcasting station transmitting a broadcast wave whose PTY code included in the DS data matches the PTY code set in the PTY code register. That is, the microcomputer 4 detects a station broadcasting the genre corresponding to the set PTY code at the frequency closest to the frequency at which the search was started, and tunes to that station. If the selected station does not exist, it returns to the station where it was listening and receives it.

During this search, the microcomputer 4 drives the muting circuit 3 to cancel noises at the time of tuning and detuning. The microcomputer 4 displays the tuned frequency on the frequency display 8 and displays the station name on the PS display 9 based on the PS code included in the RDS data.

(2) Interruption playback mode setting processing In the interruption playback (reception) mode, when the currently receiving broadcast station or another broadcast station starts broadcasting the desired content, playback of other media is stopped. It is a function of receiving, demodulating, and reproducing broadcast waves of the corresponding broadcast station. This mode is set by operating the interrupt reproduction setting key. The microcomputer 4 detects the key operation and sets a flag indicating that the interrupt reproduction mode has been set in the interrupt reproduction register of the memory 7.

For example, when the PTY reception mode is set in the mode register and the code "01" corresponding to "news" is set in the PTY mode register, the interruption reproduction mode is set and any of the broadcasting stations is set. When a news broadcast is started, the reproduction of other media is stopped, and the news program is received and reproduced.

The interrupt reproduction mode is released when the microcomputer 4 turns off the flag set in the interrupt reproduction register of the memory 7 in response to, for example, a predetermined key operation.

(3) Interrupt Prohibition Time Setting Process In this embodiment, an interrupt prohibition time for prohibiting interrupt reproduction can be set. A method of setting the interrupt prohibition time will be described with reference to FIG.

By turning on the interrupt prohibition time setting key,
The microcomputer 4 starts the processing shown in FIG. 7A. First, the maximum value (90 minutes) and the minimum value (10 minutes) of the interrupt prohibition time are stored in the interrupt prohibition time register of the memory 7 as default values. Is set (step S11). Next, when the UP key is pressed (step S1)
2) The microcomputer 4 determines whether or not the preset interrupt prohibition time is the maximum value (90 minutes) (step S13), and if not, as shown in FIG. 7B. , The interrupt inhibition time is increased by 10 (minutes) (step S1).
4). If it is the maximum value, the preset interrupt prohibition time is maintained as it is.

When the DOWN key is pressed (step S15), the microcomputer 4 determines whether or not the preset interrupt prohibition time is the minimum value (10 minutes) (step S16). Otherwise, as shown in FIG. 7B, the interrupt prohibition time is set to -10 (minutes) (step S).
17). If it is the minimum value, the preset interrupt prohibition time is maintained as it is. When the desired interrupt prohibition time is set, the operator operates the setting key (step S18). As a result, the interrupt prohibition time is determined.

(4) Interruption Reproduction Processing The interruption reproduction processing when the interruption reproduction mode and the interruption prohibition time are set will be described with reference to FIG. Here, in order to facilitate understanding, the PTY code "News"
It is assumed that “01” indicating “.” Is set. Also, the media player 21 plays music and the like, and the switching circuit 22
Selects the reproduced signal, and the speaker 23 emits a reproduced sound.

The microcomputer 4 includes, for example, 10
The process shown in FIG. 8 is periodically executed at a cycle of about 0 ms. First, it is determined from the value of the interrupt reproduction mode register whether or not the interrupt reproduction mode is set to ON (step S21). If it is determined that the interrupt reproduction mode is ON, the previous interrupt reproduction time and the interrupt inhibition time are read from the interrupt reproduction time register and the interrupt inhibition time register, and the current time is read by the timer 11. Read from Next, the read interrupt reproduction time is compared with the current time, and it is determined whether or not the interrupt prohibition time has elapsed from the previous interrupt reproduction time (step S22).

When it is determined that the interrupt prohibition time has elapsed since the previous interrupt reproduction time, the PTY contained in the RDS data demodulated by the RDS data demodulation circuit 5 is included.
PTY whose code is set in the PTY code register
It is determined whether or not it matches the code, that is, "01" (step S23). That is, it is determined whether or not news is being broadcast.

If the PTY data demodulated by the RDS data demodulation circuit 5 is "01", that is, if it is determined that news is being broadcast, the interrupt prohibition state is released and the previous interrupt reproduction of the memory 7 is performed. The time is set to the current time (step S24).

Next, the microcomputer 4 supplies a switching signal to the switching circuit 22. The switching circuit 22 responds to the switching signal, interrupts the reproduction / sound emission of the media player 21, temporarily suspends the audio signal, selects the audio signal supplied from the muting circuit 3, and reproduces the audio signal from the speaker 23 (step S25). ).

On the other hand, if NO is determined in any of steps S21 to S23, that is, if (1) it is determined that the interrupt reproduction mode is turned off, (2) the previous interrupt reproduction time (3) If it is determined that the PTY data demodulated by the RDS data demodulation circuit 5 is not "01", the FM broadcast is reproduced. Media player 21
Continue playing.

As described above, according to this embodiment, the interruption reproduction of the news is prohibited until a predetermined interruption prohibition time has elapsed since the previous interruption reproduction of the news.

For example, as shown in FIG.
It is assumed that the interrupt prohibition time is set to about 40 minutes. 6: 0
Assuming that the news broadcast has started at the A broadcast station at 0, the microcomputer 4 detects that the A station has started broadcasting the news from the PTY code supplied from the RDS data demodulation circuit 5, and switches to the switching circuit 22. Send a signal,
Play the news. Thereafter, when the news ends at 6:15, the microprocessor 4 detects the end of the news broadcast from the PTY code supplied from the RDS data demodulation circuit 5, transmits a switching signal to the switching circuit 22, and Switch to another media. Thereafter, even if the B broadcast station starts a news broadcast at 6:20, the news broadcast is not played back since interrupt playback is prohibited until 6:40.

Subsequently, the interrupt prohibition state is released at 6:40. Then, when news broadcasting starts on the C broadcasting station,
The broadcast of station C is demodulated by the interrupt reproduction process, and the user can listen to the news.

As described above, according to this embodiment, the interrupt prohibition time can be set, so that it is not necessary to listen to an undesired broadcast by the interrupt reproduction process, and it is possible to select and listen to only the desired broadcast. it can.

In the above embodiment, the interrupt prohibition time is measured from the previous interrupt reproduction time. However, the start time and the release time of the interrupt prohibition may be set.
For example, the start time and the end time can be specifically set such that the interrupt prohibition start time is *: 01 (* is a wildcard indicating an arbitrary integer) and the interrupt prohibition release time is *: 59. It may be. In this case, for example, 6:
News broadcasted at 00, 7:00, 8:00, etc. is not demodulated / reproduced because interrupt prohibition is not set. For example, news broadcasted at 6:30, 7:30, 8:30, etc. Is not demodulated because interrupt is disabled. In addition, for example, settings such as prohibiting interrupt reproduction during AM 11:00 to PM 3:00 can be made.

The present invention is not limited to the case of interrupt reproduction of a program based on the PTY code, but also the case of prohibiting the interruption reproduction (reception) of TI (traffic information) using RDS data. Applicable. The TI interrupt reproduction mode is set, for example, by setting a code indicating the TI mode in the mode register of the memory 7 and setting an ON flag in the interrupt reproduction register. Further, the interrupt prohibition time for prohibiting the interrupt reproduction of the TI is set in the interrupt prohibition time register by the same processing as that of FIG.

When this mode has been set, the microcomputer 4 periodically determines whether or not the TI reception mode has been set.
RDS that scans the broadcast station and shows the format in Figure 2
When the TP data in the data detects a broadcasting station with “1”,
It is determined whether or not the interruption prohibition time has elapsed since the previous traffic information interruption reproduction, and if not, the interruption reproduction is prohibited. On the other hand, if the interrupt inhibition time has elapsed since the previous traffic information interruption reproduction, the interruption inhibition is released, and the traffic information can be reproduced.

The present invention can be applied not only to the RDS receiver, but also to various receivers that perform the interruption reproduction process of the broadcast wave. Further, the circuit block shown in FIG. 1, the memory map shown in FIG. 3, and the setting procedures shown in FIGS. 4, 6 and 7 can be arbitrarily changed within a range in which substantially the same function can be realized.

Further, when 0 minute is further set below the minimum value of 10 minutes in FIG. 7B and 0 minute is set by operating the DOWN key, the prohibited time is set in the flow of the prohibited time setting process. An operation of executing a process of canceling the setting of the setting can be provided. For example, in step S16 of FIG.
S, that is, when it is determined that the prohibition time is the minimum value (0 minutes), a message asking the user whether to cancel the setting of the interruption prohibition time is displayed on the display unit, and the operator Whether or not to maintain the setting may be input by a key operation.

Further, an OFF mode is provided below 0 minutes,
The configuration may be such that the setting is turned off when the DOWN key is operated from the minute and the interrupt prohibition mode itself can be released.

For example, while the example has been described in which the interrupt prohibition time is changed stepwise in units of 10 minutes, the change may be made continuously. Also, the maximum value and the minimum value of the interrupt prohibition time can be arbitrarily changed. Also, step S1 in FIG.
In the example 1, 50 minutes is set as the initial value (default value). However, when the code indicating the off mode is set as the initial value, or when the prohibition time is set at the time of setting the previous interrupt reproduction mode, May set the last set time as an initial value.

For example, when the interrupt reproduction mode is set for the first time, the above-mentioned off mode is set as an initial value, and thereafter, the last set interruption prohibition time is saved, and the interruption reproduction mode is set. Then, the last saved interrupt prohibition time may be set as the initial value.

Further, in step S18, the setting is terminated by operating the setting key. However, if there is no key input for a predetermined time (for example, 5 seconds), the interrupt prohibition time setting process is forcibly performed. You may make it end.

The timer 11 has some measurement errors. In consideration of this error, a time shorter than the desired interrupt prohibition time by several tens of seconds to about 2 minutes may be set. For example, if the operator sets the interrupt prohibition time to 50 minutes,
The microcomputer 4 may set the interrupt prohibition time to be actually set to 49 minutes 30 seconds, 49 minutes, 48 minutes, or the like. For example, if you only want to listen to regular news such as 7 o'clock, 8 o'clock, 9 o'clock, etc., the interruption prohibition time is usually set to 60 minutes. If the cancellation is made exactly at 8 o'clock, there is a possibility that news starting at exactly 8 o'clock may not be heard. Therefore, by setting the interrupt prohibition time slightly shorter than the interrupt prohibition time specified by the operator, the interrupt is released somewhat earlier (for example, at 7:58 or 59: You can definitely listen to the next broadcast.

The procedure shown in FIG. 8 can be changed. For example, an interrupt prohibition mode flag is set from the last interrupt reproduction until the interrupt prohibition time elapses, and the interrupt reproduction process is executed from the on / off of the interrupt prohibition mode flag. It can be changed as appropriate, for example, by determining whether or not it is not.

[0068]

As described above, the RDS of the present invention
According to the receiver and the receiver, the interrupt prohibition condition can be set, so that only the broadcast that is originally intended to be reproduced and listened to is interrupted and reproduced, unnecessary information is reproduced, and other programs are reproduced by unnecessary information. A situation in which reproduction or the like is disturbed can be prevented.
