Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FM multiplex information receiving device, an information transmitting / receiving system, and an information receiving device for selectively calling by using data multiplexed in FM radio broadcasting waves.

[0002]

2. Description of the Related Art Conventionally, a service using an FM broadcast wave as a medium has been considered, in which service information such as character information is multiplexed with an FM broadcast wave and transmitted, and the service information is displayed on a display means provided on the receiving side. There is. This service, which is also called so-called mobile FM text multiplex broadcasting, is a visible radio (VISUAL INFORMATION RADI
O) has already been implemented.

In this FM text multiplex broadcasting, when a broadcast radio wave in which display information such as characters and numbers is multiplexed with normal broadcast audio information is transmitted from an FM broadcast station on the transmission side, the FM broadcast radio wave is a reception side terminal. Received by a radio with a display such as liquid crystal, separate FM voice information and display information such as letters and numbers multiplexed with this, convert the display information into a character code and display it on the display It is designed to be viewed by the person. As a result, the user can listen to the FM broadcast while listening to the information related to the broadcast, such as the name of the music being broadcast, the name of the artist, commentary, request votes, and even news that is not directly related to the broadcast. You can see the weather forecast, traffic information, etc. as text information.

In this mobile FM character multiplex broadcasting,
In addition to providing free service information, it has been considered to provide a paging service, that is, a selective call service, for a fee, using specific service information, for example, multiple information.

[0005]

By the way, in such a selective calling service, it is conceivable to add message information in addition to simply calling the other party, as in a general selective calling service. As this message information, the numbers that can be used by the sending side to make a call,
"Free message" that combines and combines the characters to freely create and send the contents of the message, and the sender that specifies the number of multiple fixed phrases that the receiver receiving the call has previously stored in the device There is a fixed message ".

[0006] The "free message" has a high degree of freedom as message information, but on the other hand, it causes troubles such as time-consuming input and a large information capacity per message on the transmission path.

Further, the above-mentioned "standard message" requires only a small transmission capacity on the transmission line, and does not require much labor for inputting. However, the words used in the message are always changing, and the terms and the like change with the times, so the standard message stored in advance in the device is
There is a tendency for the words to be fixed, using common words that are natural, and it is almost impossible to memorize detailed nuances, specific places, and names as fixed phrases.

In order to make up for this point, there has been considered a model which can use a self-made definition type fixed sentence in which a self-made fixed type sentence is defined and stored in the device, but the input operation of the fixed type sentence is troublesome. In addition, it is necessary for the sending side to make a call and the receiving side to receive a call to determine in advance, for each sentence, which number corresponds to which message. This may cause inconvenience such as a message having a different meaning or a message having no meaning.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fixed text that is highly expandable and has a high degree of freedom without increasing the transmission capacity used when sending a message. PROBLEM TO BE SOLVED: To provide an FM multiplex information receiving device, an information transmitting / receiving system, and an information receiving device capable of using a message according to the above and capable of keeping the definition content of a fixed text consistent between the message sending side and the message receiving side.

FIG. 5 is received by the FM radio unit 10 and
3 shows a data structure for each type of data multiplexed on FM broadcast radio waves input to a control unit 23 via an L-MSK demodulator 21 and an error correction decoder 22 of a multiplex information receiving unit 20.

Here, the type of the received data is shown in FIG.
General information of the free service shown in (a), general information of the paid service shown in FIG. 5 (b), selective call information of the paid service shown in FIG. 5 (c), and fixed form of the paid service shown in FIG. 5 (d). There are four types of sentence information.

The general information of the free service shown in FIG. 5A is information such as music titles and artist names related to FM radio broadcasting, explanations, request votes, and news not directly related to broadcasting. It is information that can be received as it is by an FM radio receiver that supports general text multiplex broadcasting such as weather forecast, traffic information, etc., service type indicating free service, information type indicating general information, program A number, the total number of pages, and free service data form a set of data blocks.

The general information of the pay service shown in FIG. 5 (b) is the FM radio reception corresponding to the character multiplex broadcasting which can be operated by some charging method, which requires a contract with the service company such as stock price information. Information that can be received by the device, a service type indicating a pay service, an information type indicating general information, a program number, the total number of pages, and pay service data make up a set of data blocks.

The selective call information of the pay service shown in FIG. 5 (c) is received by the FM radio receivers 1a to 1d or the like which can be operated by some charging method which requires a receiving contract with a paging service company. A set of data blocks is composed of possible information, a service type indicating a pay service, an information type indicating selective call information, a program number, the total number of pages, and message data.

The fixed-form sentence information of the pay service shown in FIG. 5 (d) is obtained by the FM radio receivers 1a to 1d, etc., which can be operated by some kind of charging method, which also requires a receiving contract with a paging service company. Receivable information, service type indicating a paid service, information type indicating fixed phrase information, total number of pages, and fixed form data to be stored in the fixed form data memory 28 shown in FIG. To form a set of data blocks.

Next, the operation of the above embodiment will be described. FIG. 6 mainly shows the processing contents for the received data of the character multiplex broadcast performed by the control unit 23. When the data is first received (step A1), the control unit 23 sets the service located at the beginning of the block of the data. Depending on the type, it is determined whether or not it is a paid service (step A
2).

If it is determined that the received data is not a pay service, the received data is general information of the free service having the data structure shown in FIG. 5A, so that the received data is sent and received once. Data memory 2
After the data is stored in the corresponding area 7 (step A3), it is determined whether or not the display of the general information is designated by the key operation of the key input unit 25 (step A4).

Only when it is determined that the display is designated, the received data stored in the transmitted / received data memory 27 is displayed and output on the display unit 26 (step A5), and the process is completed.

When it is determined in step A2 that the received data is a pay service, the control unit 23 then determines whether or not a contract for receiving the pay service is made and the individual information storage unit of the ROM 24. It is determined whether or not the reception contract information is stored in 24a (step A6).

If it is determined that the contract for receiving the pay service is not made, that is, if the corresponding reception contract information is not stored in the individual information storage unit 24a, this process is terminated at that point. If the corresponding reception contract information is stored in the individual information storage unit 24a, it is then determined whether the reception data is the fixed text information shown in FIG. 5D. Judgment is made according to the type (step A7).

When it is determined that the information is the fixed phrase information, the control unit 23 uses the received data to fix the fixed phrase data memory 2
Update processing of the data defining the fixed phrase stored in 8 is executed (step A8).

FIG. 7 is a subroutine showing the details of the update processing of the data defining the fixed phrase in step A8.
Here, the following variables, that is, the memory group number n indicating the storage area of the fixed number defined as shown in FIG.
(M), memory group number n $ (m) indicating the storage area of the fixed text corresponding to this memory group number n (m), m used for designating each of the storage areas, and the value of the page count counter It is assumed that p, the total number of pages p1 defined by the received fixed phrase information, V1 indicating the version information of the received data, and V2 indicating the version information stored in the fixed phrase data memory 28 are used.

At the beginning of the processing, first, an initial value "1" is set as the page count value p (step B1), and then the leading half-width character at the position corresponding to the first line in the received fixed phrase data is 4 The character portion is held as the received version information V1 (step B2).

FIG. 8 (1) shows the data structure of the first page in the standard sentence data fetched at this time. Two half-width characters 4 at the beginning of the first line are used to form a half-width character 4. The characters represent the received version information V1 "0001".

Next, the received received version information V1
Is larger than the version information V2 stored in the fixed phrase data memory 28, that is, whether the received version of the fixed phrase data is newer than the already stored version of the fixed phrase data. It is determined (step B3).

When it is determined that the received version information V1 is the same as or smaller than the version information V2, the received fixed phrase data is the same as the fixed phrase data stored in the fixed phrase data memory 28, or an old version. Since it is the standard sentence data of No need to be updated, this process is completed.

If it is determined in step B3 that the received version information V1 is larger than the version information V2, the received fixed phrase data is the fixed phrase data memory 28.
Since it is the fixed phrase data of a newer version than the fixed phrase data stored in, the received fixed form data is stored in the fixed form data memory 28 so that the received version information V1 is set as the new version information V2. The data is stored in the data memory 28 (step B4), the page count value p is then updated by "+1" (step B5), and the memory group number n ( m) and the fixed group memory group number n $ (m), the initial value "1" is set as the value m (step B6).

Then, the fixed number of 3 characters × 3 lines of half-width characters in the page indicated by the page count value p, which is the fixed-form sentence data following the version information, is used as the memory group number n (m) (here m = 1) to store it in the storage area in the fixed phrase data memory 28 (step B7).

Then, in response to this, a fixed-length sentence of 17 characters x 3 lines from the third character to the last character of the line in full-width characters following the fixed-number in the page is stored in memory group number n $.
(M) (here, m = 1) is stored in the storage area in the fixed phrase data memory 28 (step B7).

FIG. 8 (2) shows the data structure of the second page in the fixed phrase data fetched at this time.
Each fixed number of 1 ”,“ 002 ”, and“ 003 ”is stored in the storage area indicated by the memory group number n (1), and the corresponding fixed phrases of“ da ”,“ dayo ”, and“ desa ”are stored in the memory. It is stored in the storage area indicated by the group number n $ (1).

Next, after storing the three fixed phrases as one page in the fixed phrase data memory 28 as described above, the page count value p is updated and set to "+1" (step B
9), the updated page count value p is set to the value shown in FIG.
It is confirmed whether or not the total number of pages p1 defined by the fixed phrase information shown in (d) has been exceeded, that is, whether the update process based on the received fixed phrase information is completed (step B).
10).

Then, after confirming that the page count value p does not exceed the total page number p1, step B1
In step 1, the value m used for designating the storage area in the fixed phrase data memory 28 is updated and set to "+1", and the process from step B7 is repeated again, whereby the fixed phrase data memory based on the received fixed phrase data is obtained. The updating process of 28 is sequentially continued.

FIG. 8 (3) shows the data structure of the third page in the fixed phrase data fetched after the information shown in FIG. 8 (2), and is "004", "005", "006". Is stored in the storage area indicated by the memory group number n (2), and the corresponding fixed phrases of "Shinjuku", "Hiroo" and "Harajuku" are indicated by the memory group number n $ (2). It is stored in the storage area.

By performing such update processing of the standard sentence data memory 28, the standard sentence information as shown in FIG. 4 is automatically stored in the standard sentence data memory 28.

However, when it is determined that the page count value p exceeds the total number of pages p1, the updating process of the fixed phrase data memory 28 by the fixed phrase information received by the subroutine of FIG. 7 is terminated, and the main process of FIG. Also in the routine, the processing for the received data is once ended.

Further, in FIG. 6, when it is determined in step A7 that the received data is not the fixed phrase information, whether or not the received data is the selective call information shown in FIG. 5C above. Is also determined based on the information type (step A9).

When the control unit 23 determines that it is the selective call information, whether the call number in the received data matches the call number assigned to the own device stored in the individual information storage unit 24a of the ROM 24. It is determined whether or not the player's own device has been called (step A10).

If the calling number in the received data and the stored calling number do not match, this means that the call is not for itself, so this process is terminated. If they do match, however, the call is for itself. Therefore, the message data in the received data is stored in the transmission / reception data memory 27 (step A11), and then the user is informed that the call has been made by the sound emitting unit 29 (step A12).

After that, it is determined whether the message data stored in the transmission / reception data memory 27 is a fixed form sentence or not by the presence or absence of a specific code that should be added at the beginning (step A13).

Only when it is determined that the text is a fixed phrase,
As it is, the standard number is enumerated and the meaning of the message cannot be understood.
8, the fixed form numbers are sequentially converted into fixed form sentences (step A14), and the message data obtained by the conversion is displayed on the display unit 26.
Is displayed and output (step A15), and the processing ends.

FIG. 9A shows an example of message data using the fixed phrase displayed on the display unit 26 at this time, and is stored in the fixed phrase data memory 28 on the right end side of the first line. The version information is, for example, “version 0
In addition to displaying "001", the message data obtained by conversion in the second line is displayed as "Promise to have tea at Hiroo store".

If it is determined in step A9 that the received data is not the selective call information, the received data is the general information of the pay service shown in FIG. 5B. After storing the general information of the pay service in the transmission / reception data memory 27 (step A1
6) It is determined whether or not the display of the general information is designated by the key operation of the key input unit 25 (step A1).
7).

Only when it is determined that the display is designated, the received data stored in the transmitted / received data memory 27 is displayed and output on the display unit 26 (step A18), and the process is completed.

By the way, when message data using the fixed text as shown in FIG. 9A is created by the FM radio receiver 1a on the transmitting side, key input is performed as shown in FIG. 9B. The cursor keys provided in the section 25 are used to sequentially select fixed phrases while moving the position. As shown in the figure, the selected fixed phrases are already selected by being underlined or highlighted. It is displayed separately from the fixed phrase part.
Then, the fixed form number corresponding to the selected fixed form sentence is converted into a DTMF signal by the DTMF signal generation unit 31 according to the transmission instruction, and is output from the speaker 34.

Even when the message data using this fixed phrase is created, the fixed phrase data memory 2 as shown in FIG.
The version information stored in No. 8 is displayed as, for example, "version 0001", and since the sending side remembers this version information, a message that is different from the receiving side and does not make sense Even if the data is displayed on the receiving side, it is possible to confirm later that the version information is different.

In the above embodiment, the case where the service information of the selective call and the fixed form sentence is multiplexed with the FM broadcast radio wave has been described, but the present invention is not limited to this and can be applied to other broadcast radio waves. Can also be considered. In addition, the present invention can be variously modified and implemented without departing from the gist thereof.
