Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to receivers utilizing RDS data.

[0002]

2. Description of the Related Art Some FM broadcasting stations in Europe add RDS data to the original audio signal.

This RDS data is a collection of digital data relating to broadcasting stations, programs, etc., and the RDS data is a PI code ... Program identification code. It has a country code and a program code. PS data: Character data indicating the name of the broadcasting station. PTY code: Identification code for program content. news,
Shows program contents such as light music, education, sports, and information. Data is included.

Then, the RDS data is subjected to an encoding process for error correction, and the RDS data subjected to the encoding process has a frequency of 57 kHz (a value three times the frequency of 19 kHz of the stereo pilot signal). The subcarrier signal is balanced-modulated, the modulated signal is added to the monaural signal or the stereo composite signal, and frequency-multiplexed, and the multiplexed signal is transmitted by the FM wave.

In the following description, a broadcasting station that also transmits RDS data is called an "RDS station".

Therefore, if RDS data is used,
Press the auto preset key. 1. Scan and receive the FM broadcast frequency band from the lowest frequency.

2. When the RDS station is received, the data regarding the reception frequency is stored in the memory.

3. The operation of the above item 2 is repeated until the highest frequency in the frequency band. It is possible to configure a receiver that operates as described above and automatically preset the RDS station.

In the following description, the operation of automatically presetting the RDS station by using the RDS data is called "RDS auto preset".

[0010]

However, since the frequency band of FM broadcasting in Europe is 87.5 to 108 MHz and the frequency interval is 50 kHz, FM broadcasting can be received by about 100 stations on average. Therefore, when RDS auto preset is executed, a considerable number of broadcast stations are stored in the memory, but it is impossible to predict the number of the stored broadcast stations. Therefore, if the memory capacity is small, when RDS auto preset is performed, F
The memory becomes full before scanning all of the M broadcast band.

Of course, if the capacity of the memory for storage is made sufficiently large, all the results of the RDS auto preset can be stored in the memory.

However, considering the actual radio wave situation in Europe, a large number of relay stations (satellite stations) are installed and the same program can be received at a minimum of 3 to 5 stations at different frequencies. Therefore, if the memory capacity is increased, all the results of the RDS auto-preset can be stored in the memory, but at this time, many relay stations are also stored, that is, the same program with different frequencies is stored. , Will be memorized in duplicate.

In the case of such an RDS auto preset, the memory is not effectively utilized,
The number of tuning keys becomes a problem. Furthermore, even if the listener presses another tuning key, the same program may be selected (although the frequency is different), which is very inconvenient.

Further, when the RDS auto preset is executed, the RDS stations are received in the order of frequencies and the broadcasting stations are stored in the memory in the order of the frequencies. Therefore, the tuning keys are pressed in sequence and the RDS assigned to the tuning key is pressed. It is necessary to confirm or remember the station, which also makes the usability worse.

The present invention is intended to eliminate the above problems.

[0016]

When the entire FM broadcast wave band of interest is scanned, the broadcasting station "HR1" can receive at two frequencies and the broadcasting station "WDR2" as shown in FIG. 5, for example. "Can be received at three frequencies, and the other broadcasting stations" SWF2 "," HR3 ", etc. can each receive only one frequency. The reception level of each broadcasting station is also as shown in the figure.

Then, in the present invention, the broadcasting station "H
Regarding “R1”, the reception level of the “HR1” station of the first frequency is higher among the two, so the frequency data for receiving the “HR1” station of the first frequency is stored in the memory. Remember.

For the broadcasting station "WRD2", 3
Of the two, the "WRD2" station of the second frequency has the highest reception level, so the "WRD2" station of the second frequency
Frequency data for receiving the 2 "station is stored in memory.

Further, other broadcasting stations "SWF2", "HR"
3 ”and the like can be received at only one frequency, the frequency data of them are stored in the memory as they are.

The frequency data stored in the memory is
Broadcast station names are sorted by frequency, not by frequency.

That is, in the present invention, when the reference numerals of the respective parts are made to correspond to the embodiments described later, various kinds of data S32 such as a program code and character data indicating a broadcasting station name are obtained.
In a broadcast receiver adapted to be transmitted together with the main signal S17, a synthesizer type receiving circuit 10, and a demodulation circuit 32 for demodulating various data S32 from the broadcast wave signal S12 received by the receiving circuit 10. , A detection circuit 3 for detecting the reception level of the broadcast wave signal S12 received by the reception circuit 10.
5, a memory 44, and a preset key KRP.
When the preset key KRP is operated, the reception frequency f12 of the receiving circuit 10 is changed at every predetermined frequency step to scan the broadcast frequency band, and the broadcast wave signal S12 having various data S32 is scanned by this scan. The frequency data N to be received is obtained and stored in the memory 44. However, when the program code or the character data is the same in a plurality of broadcast wave signals S12,
Of the plurality of broadcast wave signals S12, the data N of the frequency of the broadcast wave signal S12 having the maximum reception level indicated by the detection circuit 35 is
This is stored in the memory 44.

[0022]

With respect to a plurality of broadcasting stations broadcasting the same program, the frequency data N of the broadcasting station having the highest reception level among them is stored in the memory 44. Therefore, broadcast stations broadcasting the same program are not redundantly stored in the memory 44, so that the memory 44 is effectively used and the usability is improved.

According to such a configuration, the CPU 41 causes the R
By executing the program of the OM 42, the following operation or processing is performed. In the following description, "broadcast station" also includes "relay station".

<< Power On >> When the power is turned on, the last channel data, that is, the frequency division ratio N of the broadcasting station which was received when the power was turned off last time, is stored in the memory 44.
The frequency division ratio N is set in the frequency division circuit 22 through the port 51.

Therefore, when the power is turned on, the broadcasting station which was receiving when the power was turned off last time is received.

Then, predetermined data is supplied to the display controller 55, data relating to the broadcasting station currently being received, for example, the reception frequency is displayed on the display device 61, and the broadcasting station being received is the RDS station. If,
The PS data included in the RDS data S32 is supplied to the controller 55 and the broadcasting station name is displayed on the display device 61. Then, after that, the processing of the CPU 41 waits for a key input from the keys KUP to KN9.

<< Selection by Key KUP or Key KDW >>
When the processing of the CPU 41 waits for a key input from the keys KUP to KN9, if the up key KUP or the down key KDW is pressed, the frequency division ratio N set in the frequency dividing circuit 22 through the port 51 is set to be lower than the current value. Is also increased or decreased by "1". However, when the frequency division ratio N reaches the maximum value or the minimum value, it is fixed at the maximum value or the minimum value.

Therefore, when the key KUP or KDW is pressed, the reception frequency f12 is increased or decreased by 50 kHz each time the key is pressed, and the broadcasting of any frequency can be selected. After the tuning, the frequency division ratio N is
It is written in the predetermined address of 4 as the data of the last channel.

<< RDS Auto Preset >> To perform RDS auto preset, press the RDS auto preset key KRP.

Then, the processing of the CPU 41 is executed by the routine 10.
Start from 0, step 101, then step 10
In 2, the work area of the RAM 43 is secured with a storage area for the frequency division ratio N, RS data, PI code and detection signal S35 for 30 stations, and this area is cleared. Frequency 8
A minimum frequency division ratio N (= 1964) corresponding to 7.5 MHz is prepared.

Next, the process proceeds to step 111, where the frequency division ratio N is set in the frequency division circuit 22 through the port 51, and the reception circuit 10 receives the frequency f12 corresponding to the frequency division ratio N. To be in a state. In this case, the reception frequency f12 is set to the lowest frequency of 87.5 MHz according to the frequency division ratio N prepared in step 103. continue,
The process proceeds to step 112. In step 112, it is determined whether or not the reception level is correctly tuned to the broadcast wave whose reception level is equal to or higher than the specified value by checking the detection signal S35. The process proceeds from 112 to step 113.

Then, in this step 113, R
By checking the presence / absence of the DS data S32, it is determined whether or not the broadcast station received in step 111 is an RDS station. It should be noted that the presence / absence of the RDS data S32 is checked by checking the ID included in the RDS data S32.
It can be done with data.

Then, as a result of this check, when the RDS station is being received, the process proceeds from step 113 to step 114, and in step 114, the RD
It is checked whether a PI code equal to the PI code included in the S data S32 exists in the PI code area of the RAM 43.

In this case, since the broadcast station and its relay station are the same program, the PI codes are the same. Or PI
If the codes are equal, there is a relationship between the broadcasting station and its relay station. Then, as will be described later, the PI code equal to the PI code included in the RDS data S32 currently being received is R
When it does not exist in the AM 43, the frequency division ratio N of the broadcast station of the same program as the currently received broadcast station is not yet stored in the RAM 43. In addition, the RDS data currently being received S32
The PI code equal to the PI code included in
3, the frequency division ratio N of the broadcast station of the same program as the currently received broadcast station is already stored in the RAM 43.

Therefore, in step 114, the process of checking whether a PI code equal to the PI code included in the RDS data S32 currently being received exists in the RAM 43 is the same as the program currently being received. It is equivalent to checking whether the frequency division ratio N of the station is stored in the RAM 43.

Then, in step 114, as a result of the check, when the PI code equal to the PI code included in the RDS data S32 does not exist in the RAM 43,
The process proceeds from step 114 to step 115. In this step 115, the frequency division ratio N, PI code and PS data of the broadcasting station currently being received are stored in the RAM 43, and the reception level of the reception signal S12 at this time is set. The detection signal S35 shown is also stored in the RAM 43. Then, thereafter, the process proceeds to step 118.

Therefore, according to steps 114 and 115, when a broadcasting station broadcasting a program different from the broadcasting station already stored in the RAM 43 is received,
Frequency division ratio N, PS data and PI of the received broadcasting station
The code is stored in the RAM 43, and the detection signal S35 of the reception level of the broadcasting station is also stored in the RAM 43.

On the other hand, when the result of the check in step 114 is that the PI code equal to the PI code included in the RDS data S32 exists in the RAM 43, the process proceeds from step 114 to step 116, and in step 116, the current reception is received. The signal S35 indicating the reception level of the current broadcasting station is compared with the signal S35 indicating the reception level of the broadcasting station of the same PI code stored in the RAM 43 in step 115, and the reception level of the currently receiving broadcasting station is compared. If it is higher than the reception level of the broadcasting station stored in the RAM 43, the process proceeds from step 116 to step 117.

Then, in step 117, the frequency division ratio N of the broadcasting station currently being received is (R in step 115
It is stored in place of the frequency division ratio N of the broadcasting station of the same PI code (stored in AM43), and the signal S35 indicating the reception level thereof is also stored in the RAM4 in place of the signal S35 up to that point.
3 is stored. Then, the process is step 11
Go to 8.

When the reception level of the broadcasting station stored in the RAM 43 is higher than the reception level of the broadcasting station currently being received in step 116, the process skips steps 116 to 117. Go to step 118.

Therefore, according to steps 116 and 117, when a broadcasting station which is broadcasting the same program as the broadcasting station already stored in the RAM 43 is received, the broadcasting station stored and the newly stored broadcasting station are newly added. Of the received broadcasting stations, the frequency division ratio N of the broadcasting station with the highest reception level is RAM
In addition to being stored in the RAM 43, the reception level detection signal S35 is stored in the RAM 43. That is, the RAM 43
The frequency division ratio N of is, when the broadcasting station of the same program is received,
It is updated to the frequency division ratio N of the broadcasting station with a high reception level.

Further, in step 112, when the reception level of the received broadcasting station is less than the specified value, the process proceeds from step 112 to step 118. Also, when the broadcasting station received in step 113 is not the RDS station, the process proceeds from step 113 to step 118.

Then, when the processing proceeds to step 118,
In this step 118, the frequency division ratio N is incremented by "1", and then in step 119, the frequency division ratio N is the maximum value 23 corresponding to the highest reception frequency 108.0 MHz.
It is checked whether 74 has been exceeded, and if not, the process returns from step 119 to step 111.

Therefore, according to steps 111 to 119, the FM broadcast wave band is scanned. When the RDS station is received by this scan, the received R is received by using the PI code.
It is checked whether the RDS station of the same program as the DS station is already registered in the RAM 43. As a result of the check in the above item, when the RDS station of the same program is not yet registered in the RAM 43, the frequency division ratio N and the reception level of the RDS station currently being received are newly set to R.
Register with AM43. As a result of the check in the above item, when the RDS station of the same program is already registered in the RAM 43, the reception level of the registered RDS station and the R currently being received.
Compare with the reception level of the DS station.

As a result of the comparison in the above item, when the reception level of the RDS station registered in the RAM 43 is higher, the frequency division ratio N of the RAM 43 is left unchanged.

As a result of the comparison of the above items, when the reception level of the RDS station currently receiving is higher, the RAM 43
The frequency division ratio N is changed to the frequency division ratio N of the current RDS station. Is executed.

When the above-mentioned items 1 to 4 are executed for the entire FM broadcast wave band, the frequency division ratio N exceeds the maximum value 2374 in step 119.

Then, the process proceeds from step 119 to step 121, where the RAM is
It is checked whether the division ratio N for 30 stations is stored in 43. If the division ratio N for 30 stations is stored, the process proceeds from step 121 to step 123.
Further, in step 121, when the frequency division ratio N for 30 stations is not stored in the RAM 43, the minimum frequency division ratio N corresponding to the lowest reception frequency 87.5 MHz, for example, as dummy data is stored in the address not stored. And a character code indicating a blank are written, and then the process proceeds to step 123.

Then, in step 123, RA
The division ratio N and PS data for 30 stations of M43 is the PS
The stations are sorted in alphabetical order (PS data code order) indicated by the data, and in step 124, the sorted division ratios N and PS data for 30 stations are transferred to the memory 44. .. At this time, the frequency division ratio N and PS data are written in the memory 44 in page order and in each page in area order.

After that, the process proceeds to step 125.
Then, the RDS auto preset is ended.

<< Selection of RDS Auto-Preset Stations >> When selecting a RDS auto-preset broadcasting station, the page key KPG and the tuning keys KN0 to KN9 are used.

That is, when the page key KPG is pressed, each time the page key is pressed, the page of the memory 44 is changed from A → B → C → A →
B → ... is selected page by page and cyclically, and at this time, characters indicating the selected page are displayed on the LCD 61.

When the page in which the frequency division ratio N of the desired broadcasting station is written is selected, the tuning keys KN0-KN
Channel selection key K corresponding to the desired broadcasting station of N9
Press Ni (i = 0-9). In this case, as shown in FIG. 4, the tuning keys KN0 to KN9 are the frequency tables FTBL.
It corresponds to the areas 0 to 9 of the above, and when the key KNi is pressed, the selected tuning key K of the selected page is pressed.
From the area i designated by Ni, the frequency division ratio N and PS data written in the area i are read, and the read frequency division ratio N is set in the variable frequency dividing circuit 22 through the port 51. It

Further, the PS data read from the frequency table FTBL is supplied to the controller 55 and LC
The broadcasting station name is displayed in D61.

Therefore, by the page key KPG and the tuning keys KN0 to KN9, the broadcasting station which is RDS auto-preset in the memory 44 can be selected.

As described above, "tuning by key KUP or key KDW", "RDS auto preset",
<< RDS auto preset station selection >> can be performed.

Although the PI code is used in step 114 in the above description, PS data can also be used.

[0074]

According to the present invention, RDS auto-preset can be performed. In this case, in particular, according to the present invention, when the RDS stations are stored, the same program is broadcasted as described in the above items. Since it is checked whether or not the RDS station in use is already stored, a plurality of RDS stations broadcasting the same program will not be redundantly stored.

Therefore, the capacity of the memory 44 can be small and the memory 44 can be effectively used. Furthermore, although the listener pressed another tuning key KNi,
The same program will not be received,
It is easy to use.

When an RDS station broadcasting the same program as the already stored RDS station is received during the RDS auto preset, the RDS station having the highest reception level is stored in the memory 44. It is possible to receive an RDS station having a good reception condition such as S / N.

Further, when the RDS stations are stored in the memory 44, the RDS stations are sorted in the order of the station names and stored in the memory 44. Therefore, when the listener selects a station with the channel selection key KNi, It is easy to understand which RDS station is registered in the key KNi, and it is easy to use from this point as well.
