More specifically, the present invention relates to a digital multiplex signal receiving apparatus that executes corresponding processing. More specifically, the received data is transmitted by FM multiplex broadcasting, and the information data includes character / graphic information and program data (operation program of the arithmetic processing unit). The present invention relates to a multiplex broadcasting receiver including the same.

2. Description of the Related Art In recent years, as one of broadcasts providing new services, development and commercialization of FM multiplex broadcasting in which a digital signal is multiplexed and transmitted in a vacant spectral region of a baseband signal of FM stereo broadcasting has been advanced. Have been.

FM multiplex broadcasting is a new medium for newly multiplexing digital signals in a frequency band higher than the audio signals of the current FM stereo broadcasting and broadcasting traffic information, character / graphic information and the like. The features are that frequencies can be effectively used, broadcasting equipment can be easily realized, and data can be received by a mobile unit so that traffic information and the like can be easily transmitted to a mobile unit such as an automobile.

Therefore, the FM multiplex broadcasting always provides necessary information to a user who has a handy type receiver as a means for transmitting traffic congestion information and the like in real time to a vehicle equipped with the receiver. Some have been put into practical use as a means of providing an inexpensive transmission path that can be accessed anywhere.

Before describing the configuration of a conventional FM multiplex broadcast receiving apparatus, an outline of the data structure in FM multiplex broadcast will be described first.

[FM Multiplex Broadcasting System] In FM multiplex broadcasting, factors that deteriorate the reception state include multipath interference and fading interference. In particular, in the case of mobile reception, the transmission path characteristics are generally very poor. Even in that case, it is desirable to have a system that can completely receive the data once. However, in actuality, there is a case where the data transmitted in one reception cannot be completely received, and in that case, it is assumed that the data to be retransmitted is received and the data that cannot be received is supplemented. . The FM multiplex broadcast service area is preferably the same as the FM stereo broadcast service area, but there are places where the average bit error rate exceeds 10 ^-2 even within this service area. Therefore, the structure of the transmitted data is
The error correction method and frame configuration are determined in consideration of such poor transmission line characteristics.

In particular, an error caused by an extreme voltage drop due to fading interference is fatal, and error correction may not be possible. Therefore, if an error that cannot be corrected is generated by adjusting the unit data length of the data to be transmitted to the average burst length of the error caused by fading, the unit data retransmitted together with the unit data described above. It becomes possible to complement by replacing with.

Further, since the error correction effect is high, a product code in which two block codes are arranged orthogonally is used as an error correction method. Therefore, the data has a two-dimensional frame structure including an error correction code in both the vertical and horizontal directions.

The transmission data has a data structure having a hierarchical structure with the data in one frame as a basic unit.

As a concrete example of what has been described above, further references (Proc. Of Vehicle Navigation & Informatio
The FM multiplex broadcasting system disclosed in n Systems Conference (1994) A4-2 pp.111-116) will be described.

FIG. 21 shows the specifications of the hierarchical structure of the above data. In layer 1, transmission path characteristics are specified. In addition to the L + R signal and the LR signal, which are normal FM stereo broadcast signals, a multiplex signal is superimposed on a higher frequency side than the LR signal.

This superposition method considers that the interference from the multiplex signal to the voice signal becomes significant when the voice modulation degree is small, and LMSK (which controls the level of the multiplex signal by the modulation degree of the LR signal is used. Level controlled Minimum
Shift Keying) method is adopted.

Layer 2 defines the frame structure of data including an error correction method. Each frame is composed of 272 blocks in the column direction, and a 16-bit BI
C (Block Identification Code) is added, and this B
Frame synchronization and block synchronization are performed based on the IC. Of the 272 blocks in the column direction, 190 blocks are packets for transmitting data, and 82 blocks are parity packets for transmitting parity in the column direction.
Each packet has a 176-bit information section in the row direction and a 14-bit CRC (Cyclic Redundancy) that is an error correction code.
Code) and an 82-bit parity part.

In other words, the transmission data is first subjected to error correction at this stage using this one frame as a basic unit.

Layer 3 defines the structure of a data packet. The data packet is BI out of each row in the frame.
It consists of 176 bits excluding C, CRC and parity.

Further, this data packet is composed of a prefix and a data block. The prefix includes information for identifying the content of the data, and specifies, for example, which program content described later the data packet belongs to.

Layer 4 defines the structure of a data group. A data group is composed of one or more data blocks. That is, based on the information in the prefix in the data packet, the data packet numbers are arranged in the order of the data packet numbers from "0" to the data blocks with the information output flag in the prefix. This data group also includes a CRC, which is an error correction code, and the transmission data is also subjected to error correction in this layer.

One data group corresponds to one display unit, that is, one page of data.

The layer 5 defines the structure of a group of information data transmitted by FM multiplex broadcasting, that is, program data. FIG. 22 shows the structure of this program data. A program of character and graphic information is composed of a plurality of data groups, and the first data group is composed of coded information related to the entire program such as a program number and the total number of pages as program management data. Following the program management data, there are a plurality of page data, and the data for each page is encoded.

The program data and page data are composed of a data header section and a data unit group. The data unit group is composed of a plurality of data units, such as a character data section and a photographic graphic data section, which are divided for each encoding.

That is, in the above data structure, the program data on the receiving side constitutes a group of data indicating a set of information. For example, in the case of traffic information, the program information indicates the congestion status at each junction of a specific route (highway, etc.), and in the case of a weather forecast, it indicates the weather forecast information in a specific area.

[Structure of Conventional FM Multiplex Broadcast Receiver] FIG. 23 is a schematic block diagram showing the structure of the conventional FM multiplex broadcast receiver 10.

The FM multiplex broadcast signal received by the antenna 12 and the tuner 14 is detected by the detection circuit 16, further passed through the band pass filter 18, and given to the LMSK demodulation circuit 20. The LMSK demodulation circuit 20 is L
Data demodulation of the MSK-modulated FM multiplex broadcast signal is performed, and the FM multiplex signal is extracted. The demodulated data signal is frame-synchronized and block-synchronized in the synchronous reproduction circuit 22 based on the BIC as described in the layer 2 in FIG. In the error correction circuit 24, the synchronized data signal is processed by the parity code and C
The error is corrected based on RC.

Therefore, the error correction circuit 24 outputs the packet data of FM multiplex broadcast (having the structure shown in the layer 3 in FIG. 8) which is normally received or subjected to error correction.

The central processing unit 40 (hereinafter referred to as CPU) extracts the data block from the input packet data, reconstructs the data group, corrects the error at the data group stage, and converts the packet data into program data. After the reconstruction, the program data is output to the display device 42. The display device 42 outputs the input program data as a figure or a character.

As the display device 42, a liquid crystal screen having a display area for one page, that is, 248 × 60 dots (corresponding to 15.5 characters × 2.5 lines in Japanese display) is used.

[0027]

Since the conventional FM multiplex broadcast receiving apparatus 10 has the above-mentioned configuration, it has the following problems.

That is, the information data transmitted by the FM multiplex broadcasting is limited to the character / graphic information such as the traffic information and the weather forecast information as described above, and when the program data is transmitted, the corresponding processing is performed. There was no receiver to do.

That is, in the FM multiplex broadcasting, each information data is divided into unit data and transmitted as a data packet. This data packet is time-divisionally transmitted for multiple pieces of information data, so the receiver side
It is necessary to determine the type of the information data and perform the processing operation corresponding to it.

Further, in that case, depending on the contents of the program,
There are cases where it is desired to select a listener from the sender side for transmission. For example, there may be a case where it is worthwhile to carry out a broadcasting focused on a specific purchaser group such as shopping information, or it may be worth broadcasting to only a limited user such as a birthday message.

There is also a case where the receiving side does not receive all broadcast programs but wants to select information.

In the configuration of the conventional FM multiplex broadcast receiving apparatus 10, it is impossible to perform transmission / reception according to the attribute of the receiver side among the character / graphic information and program data corresponding to the above case. Met.

The present invention has been made to solve the above problems, and its purpose is to execute and display a corresponding process only for information data according to the attribute of a receiver. It is to provide a possible multiple broadcast receiver.

Following this, a data group link code, which is a flag indicating whether or not the data groups are connected, and data group size data indicating the number of bytes of the data group data are included.

Further to that, there is data group data which is the body of the data to be transmitted. After that, a NULL area for length adjustment for adjusting the data group length to an integral multiple of the data block, an end code indicating the end of the data group, and a CRC code for performing error detection of the data group are displayed. Exists.

FIG. 3 is a schematic diagram showing in more detail an example of the structure of the data group corresponding to the first program management data in the program data shown in FIG.

As described with reference to FIG. 2, the heading data block DB1 has a heading start code (SOH), and the subsequent data blocks DB2 and DB3.
There is data group link code (DGL) and data of the data group size. The data group link code and the data group size are called a data group header.

Following the data group header is a program data header. FIG. 4 is a schematic diagram showing the structure of the program data header.

The data group header is followed by the information separation code (RS) and the data header parameter, and the data block DB (n + 2) (n = in the case shown in FIG. 3).
The actual contents of the program data header in the program management data start from 6). In the program data header, a program number, update data indicating that the program content has been updated, the total number of pages included in the program, a type of code included in the program, and a presentation function indicating a method of presenting information. Data, information type data indicating the type of information of the program, and display format data designating the display format of the program are included.

In each of the above data, the data block DB (n
The presentation function data included in +4) may be, for example, an operation mode in which received information data is sequentially displayed or processed (operation mode at any time), or collectively after all reception of program data is completed. Mode for displaying or executing processing (collective operation mode)
Specify whether or not. As will be described later, when the information data is program data, the presentation function data is one of operation mode data indicating which execution format the CPU 40 operates.

FIG. 5 is a schematic diagram showing the structure of the program management data unit following the program data header.

Following the data unit separation code indicating the boundary between the program data header and the program management data unit, there are data unit parameters and data unit size data indicating the size of the data unit. Data unit data exists. In a normal character / graphic information program, a data unit group including character and graphic data follows the program data header in the program management data.

However, when program data (binary code or the like) is transmitted as the information data, the receiver side has a data structure as described below in order to determine the operation mode based on the received data. doing.

That is, first, the data unit parameter in FIG. 5 includes a parameter indicating that it is data for a user to play a game based on program data, for example, broadcast program data.

This data identifies that the program data is data containing game information.

In the following, an example will be described in which the content of the subsequent unit is the program data for playing the game, depending on the parameter in the data unit parameter.

FIG. 6 is a schematic diagram showing the structure of the data unit data in the case where the game management data is included in the data unit parameter and the data unit data following it is the game management data unit as described above.

The data unit data has a type code at the head for indicating which program in the broadcast channel, and is composed of several segments following it.

For each segment, a segment length indicating the size of the segment, a control number for controlling the operation of the program data following it, and an operation mode of the program data sent by the program data can be designated. , And parameter data giving the conditions of the command given by the control number.

That is, in the above data structure,
Based on the presentation function data in the program management data header,
Designation is made as to whether it is an operation mode in which received data is sequentially executed or a batch operation mode in which processing is executed after reception of all program data is completed.

Further, the operation mode of the CPU 40 is determined by the operation mode specified by the parameter following the command, which specifies the operation mode in the program control number.

FIG. 7 is a diagram showing an example of the control command indicated by the program control number in the segment data shown in FIG.

For example, if the control number is 01H,
The operation mode is designated by the following parameter data.

When the control number is 02H, the execution start date and time of the program is designated by the following parameter data. Therefore, the FM multiplex broadcast receiving apparatus 100
After receiving the program data, starts the execution of the program after the specified start date and time, based on the timer included in the arithmetic processing unit 120.

When the control number is 03H, the deadline date and time of the program is designated by the following parameter data. When the deadline date and time is designated by this command, execution of the program of the CPU 40 is prohibited after the deadline date and time has elapsed.

When the control number is 04H, the erase date and time of the program is designated by the following parameter data. The CPU 40 constantly monitors the program data stored in the memory 30 and erases the program at the designated erase date and time. Therefore, for example, the program data can be broadcast during the day and the program data can be erased at night, according to an instruction from the broadcasting station.

When the control number is 05H, a jump to another program number is designated. This command is used, for example, when executing the same program for a plurality of programs. That is, in the case where the program to which the program data is sent is one and the program is not sent,
This control command makes it possible to specify the program to which the program is sent.

By switching the programs on the receiver side to operate, it is possible to eliminate the waste of transmitting the same program data for each of a plurality of programs.

When the control number is 06H, the comparison information is given by the parameter data following it. That is, the parameter data includes a comparison operator (for example, =,>, <, etc.) and a constant, and by comparison with the registration data input from the barcode reader / printer device 44 shown in FIG. It is possible to perform control such as. That is, on the transmission side, the data of the attribute of the user expected to be the receiver of the information in the transmission data is specified in the parameter data included after the control number 06H. Specifically, for example, the values of the comparison operator and the constant are set to predetermined values depending on whether the information is for men or for women.
On the receiver side, based on the data registered in the card, the CPU 40 determines whether or not the received data matches the attribute of the receiver of the information, and selects whether or not to store it in the memory 30. It becomes possible to control.

When the control number is 07H, it is a command for designating the module erasure, and the data of the module number designated by the subsequent parameter data is erased from the memory 30. That is, the data stored in the memory can be forcibly erased from the transmitting side to the receiving side.

When the control number is 08H, the sponsor of the information program is designated by the parameter data that follows. Also in this case, for example, it is possible to perform control such that only commercial data from the designated sponsor is stored in the memory 30 based on the registration data read from the card.

When the control number is 09H, the valid time of the CM data is designated by the parameter data that follows. As a result, when commercial data is transmitted as information data, control such as designating the effective time of the commercial becomes possible.

FIG. 8 is a schematic diagram showing a structure of a segment in the data unit data in the program management data when the control number is 06H, that is, when the comparison information is designated.

The segment including the comparison information has segment length data indicating the size of the segment at its head,
Following that, there is a program control number (6H), and after that, there is condition data indicating the conditions for comparison.

The example shown in FIG. 8 shows an example in which the conditions 1 to n exist. Each condition data includes a system variable, comparison operator data, and constant data.
System variables are what the condition is for,
For example, it indicates whether or not the condition is for age. The comparison operator is an operator for comparison operations such as =,>, and <.

Subsequent constant data is data indicating a reference value when performing a comparison operation.

Therefore, for example, when the condition 1 is about age and indicates that the program is intended for listeners under the age of 20, data indicating <is generated as a comparison operator, and a constant is generated. Data including a numerical value of 20 is included.

On the receiver side, a user having a card in which predetermined attribute data is recorded as registration data inputs the card into the bar code reader / printer device 44, and the CPU 40 displays the attribute of the listener. It is assumed that the data (sex, age, etc.) is stored in the memory 30.

Whether the program data is received, the CPU 40 synthesizes the program data based on the data from the FM multiplex signal decoding unit 15, and whether the segment data including the program control number 06H exists in the program data unit data Is determined.

When it is confirmed that the comparison information is included based on the program control number, the contents of the comparison information are classified by the following system variables, and the comparison operation is performed by the comparison operator and the constant. In the above example, the attribute data of the user registered on the receiver side (for example, the age is 16 years old) is compared with the corresponding data in the comparison information data, and the condition for age is satisfied. It is determined whether or not it has been done.

As shown in FIG. 8, the comparison information data may include not only the age as described above but also a plurality of data such as sex.

In this case, if there are n conditions,
If all of the conditions 1 to n are satisfied, the CPU 40
CPU 40 determines that the information data is stored in the memory 3
Store to 0.

FIG. 9 shows the bar code reader / FIG.
6 is a flowchart showing the flow of processing of the CPU 40 when the user inserts a card into the printer device 44 to perform the initialization operation of the FM multiplex broadcast receiving device 100.

The CPU 40 first determines whether or not a system card (including data for device initialization, attribute data, etc.) is inserted (step S1).
2).

When it is determined that the system card is inserted, the CPU 40 stores the attribute information on the card read by the bar code reader / printer device 44 in the memory 30.
(Step S13).

After that, the CPU 40 instructs the FM tuner 14 to perform a tuning operation (tuning) based on the data in the system card (step S14).

Thereafter, the card ejection is instructed (step S15), and the processing operation is completed (step S16).

FIG. 10 is a flow chart showing the flow of processing performed by the CPU 40 based on the attribute data stored in the memory 30.

The CPU 40 uses the FM multiple signal decoding unit 1
Based on the data from 5, it is determined whether or not the reception of the program data is completed (step S22).

If it is determined that the reception has not been performed, the process ends as it is (step S27).

On the other hand, if the program data is received, it is next determined whether or not the comparison information is present in the program data (step S23). If there is no comparison information, the received information data is stored in the memory 30 as it is.
(Step S26).

When the received program data includes comparison information (step S23), the comparison information is compared with the attribute data held in the memory (step S24).

If it is determined that the condition is not satisfied (step S24), the process is terminated as it is (step S24).
27).

On the other hand, if it is determined that the condition is satisfied, then it is determined whether or not there is other condition data (step S25).

If there are still other conditions, the process returns to step S24. On the other hand, if it is determined that no more condition data exists (step S25), the received information data is stored in the memory (step S2).
6).

When the storage of the information data on the memory ends, the processing operation ends (step S27).

Therefore, when the comparison information data is present in the program data, the information data is stored in the memory only when all the conditions in the comparison information data are satisfied, and even one condition is satisfied. If not, the data is not stored in the memory 30.

In the above processing, the condition (AND condition) that information data is stored in the memory when conditions 1 to n are all satisfied has been described.
When it is acceptable if any one of them is satisfied (OR condition)
It is also possible to use a combination of AND condition and OR condition.

[0109]

With the above structure, it is possible to store only the information data satisfying the condition corresponding to the attribute data registered on the receiver side in the memory and displaying it. .

Therefore, the receiver side can select and receive only the data that the user thinks necessary, and the transmitting side also transmits the information only to the user who wants to deliver the information. Is possible.
