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]

When program data is transmitted together with normal character / graphic information, the character / character at the receiver side is transmitted.

Further, in the conventional FM multiplex broadcasting,
The receiving side only receives the data from the transmitting side unilaterally. For example, it is impossible for the user to take some action based on the transmitted information, that is, it is impossible to perform the program broadcasting of the listener participation type. Met.

The present invention has been made to solve the above problems, and an object thereof is to provide a receiver side when program data is transmitted together with character / graphic information and the like in multiplex broadcasting.

FIG. 2 is a schematic diagram showing the structure of a data group including the program management data shown in FIG.

In the data group structure shown in FIG. 2, program management data is included in the data group data. The data group includes a heading start code (SOH) at the beginning thereof to indicate the start of the data group,
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.

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, a heading start code (SOH) is present in the first data block DB1 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, and thereafter there is the main body 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 transmitting program data (binary code etc.) 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 when the game management data is included in the data unit parameters and the subsequent data unit data 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 are 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 date and time when the program is erased is designated by the parameter data that follows. 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 in each of the 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 following parameter data. 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 diagram showing an example of the case where the control number is 01H, that is, the operation mode is designated. FIG. 8A is a segment including the operation mode parameter (indicated by * in the figure). 2B shows the correspondence between the operation mode parameter and the operation mode.

When, for example, 00H is specified as the parameter data after the control number 01H, the program interlocking mode is specified as the operation mode. This specifies, for example, an operation mode in which program data is transmitted in module units and is executed in module units on the receiver side in conjunction with other media such as television broadcasting.

For example, there is a case where a quiz or the like according to the contents of the television broadcast is transmitted as program data for each question, and the CPU 40 receiving the quiz executes the quiz as needed. That is, in the presentation function data in the program management data header shown in FIG. 4, the operation mode is designated at any time.

At this time, on the receiving side, the user having a card in which predetermined data is recorded as registration data inputs the card into the bar code reader / printer device 44, and the CPU 40 executes the received quiz. It is possible to adopt a configuration in which the processing of the program for starting is started. That is, only a user having a specific card can participate in a quiz program linked to a television broadcast or the like. In this case, the user inputs an answer to each question from the data input device 38, and the CPU 40
Determines the correct answer / incorrect answer based on the input answer and prints the corresponding message on the card accepted in the barcode reader / printer device 44.

As the television broadcasting progresses, a quiz based on the program data transmitted subsequently is output, and in response to this, the user inputs an answer and a corresponding message is printed on the card. It is possible to take.

When 01H is designated as the operation mode data, the accumulation mode is designated and the transmitted program is once stored in the memory 30 and the processing is collectively performed after the reception of the entire program is completed. To be executed. However, in this case, for example, the operation mode is such that the program is executed only when the registration data in the card read from the barcode reader / printer device 44 is predetermined data.

Therefore, in this case, it is possible to implement a broadcast mode in which only a user having a specific card can receive, for example, a horoscope or a quiz for guessing the result of a TV drama.

When 02H is designated as the operation mode data, the immediate execution mode of the program is designated. In this case, the programs are collectively received, and the execution of the programs is started after the reception is completed. Since data input from the card is not required, in this execution mode, all users having the FM multiplex broadcast receiving apparatus 100 can receive data according to the execution of the program.

When the operation mode data is 03H,
The normal information service mode is designated, data such as character / graphic information is received, and the data is displayed on the terminal as it is.

The information in the case where the operation mode data is 03H is not limited to the above case, and it is also possible to broadcast, for example, earthquake information. When the above emergency information is received, the received information data is immediately displayed on the display 36.

FIG. 9 is a schematic diagram showing the structure of the page data header in the page data in the program data shown in FIG.

The only difference from the structure of the program management data header is that the total page number data in the data block DB (n + 3) is page number data, and the description of the other parts is omitted.

That is, the total number of pages of each program data is designated by the program management data header, and each page data shows the program number and data of the data block DB (n + 2) regarding which position of which program it is. The block DB (n + 3) is identified by the page number.

FIG. 10 is a schematic diagram showing the structure of a page data unit following the page data header in the page data.

In this case, the basic structure is the same as that of the program management data unit shown in FIG.

The point of difference is that the data unit parameters are structured to indicate whether the following data is, for example, program data of game data or screen data (image information) of game data. is there.

FIG. 11 shows the data unit data as
It is a schematic diagram which shows a structure when program data, for example, a program of game software, is included.

At the beginning of the data unit data, there is a type code indicating the type of the following data, and subsequently there is module number data indicating the module number which is the operation unit to which the program belongs. Following the module number data, multiple segments are included. Each segment data consists of a segment length indicating the size of the segment, line number data indicating the program line number, command number data indicating the program contents, and arguments. Contains data.

Therefore, for example, the program control number 01H
When the operation mode data value subsequent to is 00H and the program link mode is designated, the CPU 40 performs the following processing.

That is, based on the module number of the received data unit data, the program is executed in the order of line numbers in module units.

FIG. 12 is a schematic diagram showing a structure when image data of game data is transmitted as data unit data.

The difference from the structure of the data unit data in FIG. 11 is that each segment has a segment length and 1
The point is that the image data for the screen is included.

By combining the configurations of the data unit data shown in FIGS. 11 and 12, it is possible to efficiently transmit the program portion and the screen information portion of the game software.

The operation of the CPU 40 will be described in more detail below. FIG. 13 is a diagram showing a flow of processing of the CPU 40 when the control based on the input data from the barcode reader / printer device 44 in FIG. 1 is not performed.

When the processing is activated (step S11), the CPU 40 determines whether or not the program is being received.
A determination is made based on the data from the M multiplex signal decoding unit 15 (step S12). If the program has not been received,
Processing again returns to the beginning of the decision, forming a loop.

On the other hand, when it is determined that the program is received (step S12), the information data is extracted based on the data from the FM multiplex signal decoding unit 15 and the information data is stored in the memory 30 (step S12). S13).

Then, it is judged whether or not the program is in the immediate execution mode, based on the presentation function data in the program management data header (step S14).

If the program is in the immediate execution mode, the CPU
The 40 executes a corresponding process based on the program data for each module stored in the memory 30 (step S15).

If the program is not in the immediate execution mode (step S14), it is determined whether or not the program is in the emergency mode (step S16).

In the case of an emergency mode program such as typhoon or earthquake information, the information is immediately displayed (step S17).

If the program is not the emergency mode program, the process returns to the determination as to whether or not the program is received again (step S1).
2).

FIG. 14 is a flow chart showing the flow in the case where CPU 40 performs the processing based on the received data based on the registration data recorded on the card. CPU
When the process is started (step S21), the device 40 determines whether or not a card is inserted in the barcode reader / printer device 44 (step S22). If the card has not been inserted, the process ends (step S33).

On the other hand, when the card is inserted, the registration data is read and the value is read by the CPU 40.
Is input to On the other hand, the CPU 40 determines whether or not the program reception is completed based on the data from the FM multiplex signal decoding unit 15 (step S23).

At this time, the registration data is compared with the content of the received program, and it is also determined whether the execution / display of the program is permitted by the registration data.

When it is determined that the program is not received or the execution / display of the program is not permitted based on the registration data, the card ejection is instructed (step S
32), the operation ends (step S33).

On the other hand, if it is determined that the program is received and the execution / display of the program is permitted based on the registration data, then it is determined whether the operation mode is the program interlocking mode. Is determined (step S2
4).

That is, the operation mode is determined based on the parameter following the program control number 01H in the program management data unit. When it is determined that the program link mode is set (step S24), the CPU 40 executes a corresponding process based on the received program data stored in the memory 30 in module units (step S25).

When it is determined that the execution of all the program data is completed (step S26), the card ejection is instructed (step S32), and the process is completed (step S33).

On the other hand, if it is determined that the execution of the entire program is not completed (step S26), a loop is formed to determine whether the reception of the next module is completed, and the standby state is set ( Step S27).

When it is determined that the reception of the next module is completed, the CPU 40 executes the corresponding process based on the next program module stored in the memory 30 (step S25).

In the above case, for example, whether or not the operation of the program module is finished is instructed by the command number and argument included in the segment in the structure of the data unit data shown in FIG.

When it is determined that the program interlocking mode is not set (step S24), it is subsequently determined whether or not the storage mode is set based on the parameter data following the program control number 01H (step S28).

When it is determined that the storage mode is set, when the completion of reception of the entire program is detected, the programs are collectively executed (step S29). Then, the card ejection is instructed (step S32), and the operation ends (step S33).

If it is determined that the storage mode is not set (step S28), then it is determined whether the information service mode is set (step S30). When it is detected that the information service mode is set, the CPU 40
Information corresponding to the display 36 is displayed based on the data stored in the memory 30 (step S
31).

When the mode is not the information service mode or after the information display is finished, the card ejection is instructed (step S32), and the operation of the CPU 40 is finished (step S33).

[Second Embodiment] In the first embodiment, when the FM multiplex broadcast receiving apparatus 100 transmits program data, operation mode data (presentation function data, operation mode) included in the information data is transmitted. The configuration in which the operation on the receiver side is controlled by the parameters) has been described.

In the second embodiment, the configuration and transmission method of a transmitter for transmitting an FM multiplex broadcast program having the above structure will be described.

FIG. 15 is a schematic block diagram showing the structure of the FM multiplex broadcast transmitter. FM multiplex broadcast transmitter 20
Reference numeral 0 denotes a data input terminal 202 for inputting program data, a knitting / sending control unit 204 for forming a data packet containing the program data as data block data based on the program data input from the data input terminal 202, and As for the general program input terminal 208 for inputting program information data and general program data,

And

FIG. 16 is a flow chart showing a flow for creating an information program, an immediate execution mode program and a storage mode program.

Each program data is created (step S4)
1).

Based on the program data of the program data and the program data of the general program, they are combined, modulated, amplified by an amplifier, and transmitted as an FM broadcast (step S42).

FIG. 17 is a flow chart showing the flow in the case of transmitting program data in the program link mode.

On the basis of the program data input from the data input terminal 202, the composition / transmission control section 204 generates packet data in module units (step S51).

At this time, in the composition / transmission control section 204, the operation mode is designated as the presentation function data in the program management data header at any time, and the program interlocking mode (as the parameter value following the program control number 01H in the program management data unit 00H) is designated.

Then, it is determined whether or not it is time to send out the module, in accordance with broadcasting on another medium such as television broadcasting (step S52).

When it is judged that it is the sending time, the synthesizing and sending control section 206 LMSK-modulates the packet data of the general program and the time-divided data, and F
It is transmitted as M broadcast (step S53).

Then, it is judged whether or not the transmission of the final module of the corresponding program data has been completed. If the transmission of the final module has not been completed, the process returns to module creation (step S51).

On the other hand, if the sending of the final module is completed, the sending operation ends (step S55).

FIG. 18 is a schematic diagram showing a data transmission method in the case of transmitting a program-linked program as a time series.

In the first data transmission, program management data and subsequent page data are transmitted.
In this case, when sending new program data, the program number and content update flag of the data block DB (n + 3) in the program management data header shown in FIG. 4 are updated. The unit of data sent at one time may be one module or a plurality of modules. When a plurality of modules are sent at the same time, the module number in the data unit data shown in FIG. Thus, it is determined whether the transmission data is a single module or a plurality of modules.

Further, the same content is transmitted two or three times without changing the content update flag for each transmission unit. As a result, even if a reception error that cannot be error-corrected occurs on the receiving side, the portion in which the reception error occurs is replaced with the corresponding portion broadcast later, so that complete data reception is realized.

Subsequently, in the second transmission of the module, the program management data and the page data are simultaneously transmitted again. At this time, the content update flag is also updated.

Therefore, on the receiving side, when the first transmission unit is received and the operation mode is designated at any time based on the presentation function data in the program management data header, the module in the first transmission unit is specified. The program is executed on the basis of the data, and it stands by until the next module data is transmitted.

After receiving the second transmission unit, the first
The program is executed in module units in the same manner as the first time. After that, in the same way, the program module is transmitted in conjunction with the progress of television broadcasting,
On the receiving side, the program is executed in module units as needed.

FIG. 19 is a diagram showing a transmission method of program data in the accumulation mode as a time series.

In the first data transmission, the program management data and page data are transmitted at the same time. At this time, the collective operation is designated based on the presentation function data in the program management data header, and the storage type program (the program to be collectively processed is performed by the parameter data following the program control number 01H in the program management data unit. ) Is specified.

Then, the second transmission is carried out,
At this time, the update flag is not changed and the program management data is not transmitted. Therefore, on the receiving side, based on the total page number data included in the program management data received first, the data is received and stored in the memory until the reception of the final page data is completed.

Also in this case, the unit of data transmission is
It can be a single module or a plurality of modules, and the same content is transmitted two to three times for each transmission unit.

FIG. 20 is a diagram showing a time-series method of transmitting information type programs. In this case, since different program data are transmitted at each time, program management data and page data are transmitted in each transmission unit. Therefore, as a matter of course, every time each transmission unit is transmitted, the program number and the content update flag in the program management data are updated. In this case also, the unit of data transmission may be one module or a plurality of modules, and for error correction, transmission may be performed two to three times without changing the update flag for each transmission unit. Done.
