It is being put to practical use as o).

Specifically, an FM radio wave with a liquid crystal display provided on the receiving side transmits the electric wave in which display information such as characters and numbers is multiplexed on an ordinary FM broadcasting radio wave from the FM broadcasting station on the transmitting side. By receiving the radio wave, the FM broadcast radio wave is separated from the display information such as characters and numbers, and the display information is converted into a character code and displayed on a liquid crystal display so that the user can visually recognize it. As a result, the user can visually recognize, for example, the weather forecast, traffic information, and the like by characters. In this mobile FM text-based multiplex broadcasting, it is considered that in addition to providing free service information, a fee is charged for specific service information.

[0004]

When providing the pay service information in the above-mentioned mobile FM text multiplex broadcast to the user, the business operator of this mobile FM text multiplex broadcast is used by the user in some way. You need to collect the fee. However, if the user simply tries to collect the fee according to a monthly payment contract between the business operator and the user, there is a problem that the user is likely to be late in payment and the management of the user becomes complicated.

On the user side, there is a problem in that the user must pay the usage fee to a business operator or a financial institution, which imposes a heavy burden on the user. Furthermore,
In the case of mobile FM character multiplex broadcasting, it is practically difficult to stop providing service information only to users who are in arrears due to the use of FM broadcast waves.

Therefore, according to the present invention, when broadcasting pay service information, the process of paying the usage fee is simple for the user, and the user can be managed without complication for the business operator. It is an object to provide a service information receiving device and an information storage medium.

[0007]

In order to solve the above problems, a service information receiving apparatus according to the present invention is a service information receiving apparatus for receiving and displaying pay service information transmitted from a transmission source. An apparatus main body in which an information storage medium storing the reception control information of the service information is detachable, and a storage unit for reading and storing the reception control information from the information storage medium mounted in the apparatus main body. ing. Further, the reception control information is information indicating a reception valid period of the pay service information, and determines whether the information indicating the reception valid period is valid or invalid. It further has reception processing means for prohibiting display.

Further, the apparatus main body further comprises an instruction means for storing the reception control information stored in a removable information storage medium in the storage means, and detects loss of memory in the storage means. In addition, the apparatus main body further includes control means for re-storing the reception control information stored in the removable information storage medium in the storage means. The storage means may further include a writing means for writing information indicating that the reception control information is stored in the information storage medium, or the storage means may store the reception control information. Writing means for writing the information to the information storage medium, wherein the control means stores the information indicating that the reception control information is stored in the storage means in the information storage medium. The reception control information stored in the information storage medium is re-stored in the storage means. In addition, it further comprises display means for displaying the storage state of the storage means.

Further, the information storage medium according to the present invention can be attached to and detached from a service information receiving device which receives and displays the paid service information to be transmitted, and stores the reception control information of the service information. In addition, a writing area for writing information indicating that the control information is stored in the service information receiving device is provided.

[0010]

When the information storage medium is attached to the main body of the service information receiving device, the storage means reads and stores the reception control information stored in the information storage medium.
Therefore, it is possible to control reception of service information without always mounting the information storage medium on the main body of the apparatus. That is, when receiving this type of service information, the prepaid method is adopted, and the information storage medium is sold in advance, and only when this information storage medium is mounted in the receiving device,
It is considered to make pay service information available. On the other hand, with regard to the receiving device, it is a multifunctional device that not only receives paid and free service information, but also mounts an information storage medium in which various programs are stored to generate functions other than information reception. It is also considered. Therefore, if a receiving device is used in which the information storage medium is attached to the receiving device as a condition for using the paid service information, when the paid service is used, other information such as a program stored in the device body is used. It becomes impossible to mount the storage medium, and it becomes impossible to realize a predetermined function. However, as described above, the storage means reads and stores the reception control information stored in this information storage medium. Therefore, even if the information storage medium is not always attached to the main body of the apparatus, it is possible to control reception of service information, and by mounting the information storage medium storing various programs, functions other than information reception can be achieved. Can be generated.

Further, if the reception control information is information indicating the reception valid period of the pay service information, the period can be managed only by the service information receiving device based on this. Also,
When the reception processing means determines that the information indicating the valid reception period is invalid, the display of the service information is prohibited, thereby preventing the unauthorized use of the service information beyond the valid reception period. Further, in the configuration including the instructing means, the reception control information stored in the storage medium is written in the storing means at the time when the instruction by the instructing means is given. Furthermore,
When the memory of the storage unit is lost, the control unit rewrites the data so that the reception control information in the storage unit is reliably stored. In addition, by writing the information indicating that the reception control information is stored in the storage means by the writing means, it is possible to indicate whether or not the information in the storage medium is already stored. Further, by displaying the storage state of the storage means by the display means, this can be confirmed from the outside. Further, when the information indicating that the reception control information has been stored is stored in the information storage medium, the control unit re-stores the reception control information stored in the information storage medium in the storage unit. That is, when the same information storage medium is mounted again in the apparatus main body, it is possible to recognize that the information of the storage medium has already been stored by the information indicating that the reception control information has been stored. In this case, by re-storing, the reception control information stored in the information storage medium can be updated and stored in the storage means.

In the information storage medium having the above-mentioned configuration, since the writing area for writing the information indicating that the control information is stored in the service information receiving device is provided, the writing in this area is performed. It is possible to identify whether or not the information of the information storage medium is already stored in the receiving device.

Next, the operation of the service information receiving apparatus 1 will be described with reference to the flowcharts shown in FIG. The data and registers shown below are used in the flow. Date data HD: from 1994 to 2 as well as the use end year data SSYD and the use end date data SSDD
4-bit data indicating up to 2010 and 365 days from 1st
It is composed of 0-364 9-bit data corresponding to the day. Current year data register GYR: 4 bits and 1
The current year from 994 to 2010 is stored. Current date data register GDR: 9-bit configuration, which stores 0-364 current dates corresponding to 1st to 365th. (Note that GR indicates both GYR and GDR registers.) Date calculation register HZR: Stores intermediate data when calculating the use end date.

Allowed program number register KBR1 KBR2 KBR3 KBR4: KBR1 to KBR1 to 3 store the program numbers that are decided to be viewed visually, and KBR4 always stores "0". Increment register NR: Stores a value for designating KBR1 to KBR4.

That is, the reception processing unit 43 in the service information receiving apparatus 1 starts its operation according to the flow shown in FIGS. 11 to 14 when the power is turned on, and monitors the reception of the multiplex broadcast date data HD. (SA1). When the multiplex broadcast date data HD is received, the multiplex broadcast date data HD is stored in GR. Here, since GR indicates both the GYR and GDR registers as described above, of the received date data HD, 4-bit current year data is stored in the current year data register GYR, and 9-bit data is stored. The current date data is stored in the current date data register GDR (SA2).

Next, after performing a main body RAM check process which will be described later, it is detected whether or not the IC card 2 is mounted in the slot 22 (SA4), and if not mounted, SA34 in FIG. 14 is selected. move on. Then, when the IC card 2 is inserted into the slot 22, the state of the flag MF stored in advance in the IC card 2 is read, and M
It is determined whether or not F = 1 (FIG. 12SA5). As a result of this determination, if MF = 1 and the IC card 2 is unused, this day is the use start date of the IC card 2. Therefore, the current year data stored in GYR is used as the start-of-use year data SKYD, and EEPRO
At the same time as writing to the use start date data write area 52b of M52, the current date data stored in GDR is written to the use start date data write area 52b as use start date data SKDD (SA6).

Next, the effective period relative value data UD is read from the effective period relative value data storage area 52a of the EEPROM 52.
Read the validity period relative value data UD and GDR
The current month date data stored in is added and the value is stored in the date calculation register HZR (SA7). Subsequently, it is determined whether the HZR value is 364 or less (SA8). Here, if the value of HZR is 364 or less, the use end date can be indicated by the current year and the current month date + valid period relative data without moving up the value of “year”. Therefore, in this case, the current year data stored in the GYR is directly written as the use end year data SSYD in the use end date data writing area 52c (SA9), and the “current month date + Validity period relative data "use end date data SSD
As D, the data is written in the usage end date data writing area 52c (SA10). Thereafter, in order to indicate that the IC card 2 has been used, the flag MF is reset (SA13), the pay broadcast reception mode is set (SA14), and the pay program reception setting process (described later) Execute SA15).

However, as a result of the determination in SA8, if the value of HZR exceeds 364, the value of 0 to 364 corresponding to 1 to 365 days is used unless the value of "year" is advanced. Cannot be represented. Therefore, the value of the current year data stored in GYR is incremented, and this incremented value is used end year data SS
The data is written in the usage end date data writing area 52c as YD (SA11). Subsequently, 364 is subtracted from the “current month date + effective period relative data” stored in the HZR, and the value is written in the same use end date data writing area 52c as use end date data SSDD (SA1
2). After that, the processes of SA13 to SA15 described above are performed, and the process returns to SA1.

On the other hand, if the determination result of SA5 is MF = 0, this IC card 2 has already been used. Then, in the case where the use has been started, first, the use end year data SSYD and the current year data GYR are compared to determine whether they are equal (SA16). If the result of this determination is that they are not the same, it is clear at this point that the IC card 2 has not yet expired, and in this case the process proceeds to the determination of whether the transfer setting SW 91 has been pressed. (SA19). And this transfer setting S
If W91 is not pressed, the process from SA21 is not performed and only the pay broadcast reception mode is set (SA2
0), if pressed, proceed to SA21 in FIG.

When SSYD = GYR in SA16, the end-of-use year data and the current year data match. Therefore, next, use end date data SSDD
And the current date data stored in GDR,
It is determined whether the two are equal (SA17). If the result of this determination is that the two are not equal, the IC card 2 has not yet expired, so if the transfer setting SW 91 is not pressed, the pay broadcast reception mode is set and SA1 is set. Return to.

However, when SA16 is SSYD = GYR and SA17 is SSDD = GDR, the end-of-use year data and the current year data, and the end-of-use month / date data and the current month / date data match. Since this is the end date of use of the IC card 2, the non-pay broadcasting reception mode is forcibly set (SA18). By the processing of SA18, the setting of the pay broadcast receiving mode is prohibited, and as a result, only in the period indicated by the valid period relative value data UD,
Reception in pay broadcast reception mode is allowed.

On the other hand, in SA21 of FIG. 13 which proceeds when the transfer setting SW 91 is pressed, the current year data stored in GYR is set as the transfer start year data JKYD, and EE is set.
The transfer start date data writing area 52f of the PROM 52 is written, and the current date data stored in the GDR is written in the transfer start date data writing area 52f as the transfer start date data JKDD. further,
The use end year data SSYD is written in the body transfer end date data writing area 47c of the RAM 47 as the body transfer end year data HJSY, and the use end date data SSDD is written in the body transfer end date data HJS.
The data is written in the same area 47c as D (SA22).

Next, it is determined whether or not the deadline reduction SW 92 has been pressed (SA23). If not, it is further determined whether or not the confirmation SW 93 has been pressed (SA3).
0), if the confirmation switch 93 is also not pressed, the process returns to SA23. Therefore, when neither the deadline reduction SW 92 nor the confirmation SW 93 is pressed, SA23 → SA30
→ The loop of SA23 is repeated to maintain the standby state. When the deadline reduction SW 92 is pushed first,
It is determined whether or not the main body transfer end date data HJSD is "0" (SA24), and if HJSD = 0, the main body transfer end year data HJSY is decremented in SA25, and then the main body transfer end date is determined. The initial value “364” is written as the data HJSD (SA26). Also, SA
As a result of the determination in 24, when HJSD ≠ 0,
Decrement and update the data HJSD for the end date of the transfer of the main body (SA27). Therefore, the completion date of transfer of the main body is decreased by one day each time the expiration date reduction SW 92 is operated.

Further, the main body transfer end year data HJSY and the current year data GYR are compared to determine whether they are equal (SA28). If the result of this determination is that they are not the same, it is before the end of the main body transfer at this time, and the aforementioned standby state is maintained until the confirmation SW 93 is pressed. If HJSY = GYR in SA28, the main unit transfer end year data and the current year data match.
Therefore, next, the main body transfer end date data HJSD is compared with the value GDR + 1 indicating the next day of the current date, and it is determined whether they are equal (SA29). As a result of this determination,
If HJSD = GDR + 1, the main body transfer end date is tomorrow, and in this case, the process proceeds to SA31 without waiting for the operation of the confirmation SW 93.

As a result of the determination in SA29, HJSD ≠
If it is GDR + 1, the flow proceeds to SA31 on condition that the confirmation SW 93 is pressed. And this SA
In 31, the transfer end year data HJSY and the transfer end date data HJSD of the main body are transferred to the transfer end date data writing area 52g of the IC card 2, respectively.
Write as YD and transfer end date data JSDD.
Further, the transfer function use flag JK on each of the IC card 2 side and the RAM 47 side to indicate that the transfer function is used.
F and HJKF are set (SA32), the pay broadcast receiving mode is set (SA33), and the process returns to SA1.

On the other hand, if it is determined in SA4 of FIG. 11 that the IC card 2 is not installed, SA3 of FIG.
In step 4, the transfer function use flag HJKF of the RAM 47 is checked. Then, HJKF = 0, and the IC card 2
If is not installed and the transfer function is not used, immediately set the non-pay broadcasting mode (SA3
7). When HJKF = 1 and the transfer function is used, the main body transfer end year data HJSY and the current year data GYR are compared (SA35), and if both are not equal, it is within the transfer expiration date. Therefore, the pay broadcast reception mode is set (SA38). However, HJSY =
If it is GYR and the transfer end year data and the current year data match, the main body transfer end date data HJSD and the current date data GDR are further compared (SA
36). If HJSD = GDR, since the transfer valid period has expired yesterday, the non-paid broadcast reception mode is set (SA37). Also, HJSD ≠ GDR
If so, since it is before the end date of transfer of the main body, the pay broadcast reception mode is set (SA38).

The main body RAM check in SA3 of FIG. 11 is performed according to the flow shown in FIG. 15, and it is determined whether or not the check data HRD is "10100101" (SB1). And HRD = 10100101
Therefore, if the RAM 47 is operating normally, the processing based on this flow is terminated without performing the subsequent processing. However, if HRD ≠ 10100101 and it is not operating normally, the display will indicate "The data in the main unit is corrupted, the data will be initialized. Please replace the backup battery immediately". 6 to 5 seconds (SB2).

Next, after all "0" s are written and initialized in the RAM 47 in the main body (SB3), "1010010" indicating a normal operation state is displayed in the RAM function check area 47d.
1 ”is written (SB4). Subsequently, it is determined whether or not the IC card 2 is attached (SB5).
If the IC card 2 is mounted, and the transfer function use flag JKF of the IC card 2 is "1" and the transfer function is used (SB6), the transfer end year and month of the IC card 2 side The data JSYD and JSDD are copied to the main body transfer end date data writing area 47c of the RAM 47 as transfer end year and date data HJSY and HJSD (SB7, SB8). Further, the transfer function use flag HJKF is set to indicate the use of the transfer function (SB
9).

On the other hand, the reception processing unit 43 has the same functions as those shown in FIGS.
In parallel with the process shown in FIG. 15, the process shown in FIG. 16 is executed in parallel to monitor the reception of HI, which is an ID indicating the program guide (SC1), and when the HI is received, the program guide data is fetched (SC2 ), A program selection screen creation process described later (S
After executing C3), the program content data is fetched (SC4), the program selecting operation process (SC5) described later is executed, and then the process returns to SC1.

The program selection screen creation process (SC3) is as follows.
It is performed according to the flow shown in FIG. 17, and after drawing the table items and the frame (SD1), the program names of BM1 to N are displayed (S).
D2). As a result of the processing of SD1 and SD2, FIG.
As shown in (A), "program name" and "pay" are displayed on the display unit 6.
A frame is displayed with the table items of "Sample Program". Next, draw "○" in the "Paid" column of the program with pay broadcast code UH = 1 (SD3), and draw "○" in the "Sample program" column of the program with sample program presence code MB = 1. Yes (SD4). Therefore, for example, assuming that the received signal has the data shown below and in FIG. 9, the above processing causes the “program name” to be “program A” to “program” as shown in FIG. Is displayed, and in the “Paid” column, “○” is displayed in correspondence with “Program” to “Program”.
In the “Sample Program” column, “◯” is displayed corresponding to “Program” and “Program”.

BS = 4 BM = Program A, UH = 0, MB = 0, BB = 1 BM = Program, UH = 1, MB = 0, BB = 2 BM = Program, UH = 1, MB = 1 , BB = 3 BM = program, UH = 1, MB = 1, BB = 4 In SD5, it is determined whether or not the pay broadcast reception mode is set. If not, the pay broadcast code UH
The "Paid" column of the program of = 1 is shaded (SD
6), the "program name" column of the program with UH = 1 and the sample program presence code MB = 0 is shaded (SD7). As a result of the processing of SD6 and SD8, as shown in FIG. 20 (A), a shaded area is displayed in the "program name" column of "program" and the "pay" column of "program" to "program". It That is, the shaded portion of the "program name" column indicates that the program is a pay program without a sample program, and the shaded portion of the "pay" column indicates that the program is a non-displayable pay program.

However, in the pay broadcast receiving mode, the process proceeds from SD5 to SD8 and the pay broadcast code UH = 1.
The "Paid" column of the program is shaded. Next, NR is "1"
After setting (SD9), the shading in the "pay" column of the KBR value indicated by this NR is erased (SD10). Here, the permitted program number register KBR is set to KBR1 to KBR1 as described above.
4 and KBR1 to KBR1 to program numbers (2-4
No.) is stored, and at this time, program numbers that are decided to be viewed by paying are stored in order from KBR1.
In BR4, "0" is always stored.

Therefore, first in SD9, NR = 1 is set, and then in SD10, the shaded part of the "pay" column of the program number corresponding to the value of KBR1 is erased, whereby the program of the program number is viewed as pay viewing. Indicates that it is selected.
Next, the sample program presence / absence code M of the program having this KBR1 value
It is determined whether or not B = 1 (SD11). If MB = 1 and there is a sample program, the "sample program" column corresponding to the program is shaded (SD12). This indicates that this program is not required to be viewed because this program has been selected for pay viewing. Subsequently, after incrementing the NR (SD13), it is determined whether or not the KBR value indicated by the incremented NR is "0" (SD14), and if it is not "0", the process returns to SD10,
If it is "0", this program selection screen creation processing is ended.

Therefore, for example, if the program numbers are stored in all of KBR1 to KBR3, SD12 to SD1
The loop of 6 is repeated 3 times, and when NR = 4, KBR4 is always "0", so SD
The process proceeds from 14 to the stop process. In addition, for example, “MB2 = program” and “MB4 = program” (this “MB
4 = “program” is a sample program) is previously selected, the loop is repeated twice, and as shown in FIG. 20B, the “pay” column of “3. program” is displayed. The shaded area remains, and the shaded area is added to the “Sample Program” column of “4. Program”. In other words, it is indicated that the pay program is not selected by the shading in the "Pay" column, and the pay program is selected by the shading in the "Sample program" column.
It is shown that the sample program cannot be viewed.

On the other hand, the pay program reception setting process (see FIG. 12).
SA15) is performed according to the flow shown in FIG. 18, after drawing table items and frames (SE1), the program names of BM1 to N are displayed (SE2), and the pay broadcast code UH = 0.
The (free) "Program name" and "Settings" fields are shaded (SE
3). By this processing of SE1 to SE3, FIG.
As shown in, the display section 6 displays table items and frames of “program name” and “setting”, displays “program a” to “program” in the “program name” column, and displays free programs. A shaded area is displayed on a certain program. As a result, the pay programs "program" to "program" to be selected become clear without being shaded.

Next, the value (any one of 1 to 3) of the pay program permission number data UBD is stored in the program permission calculation register BZR (SE4), and after setting the initial value "1" to NR (SE5), It is determined whether SW1 to SW9 have been pressed (SE6). Here, SW1 to 9 are keys corresponding to “1” to “9” of the hiragana / numeral input key group 11 when the character / numeral selection key 9 shown in FIG. 2 is in the state of numeral selection. is there. If any of these SW1 to SW9 is pressed, the pressed SW number is the total number of programs B
It is determined whether or not S (BS = 4 as described above in this example) or less (SE7), and if not, it returns to SE6. If it is equal to or lower than BS, it is determined whether or not the pay broadcast code UH having the same program number as the SW number is "1" (SE8).

If UH = 0 and there is no charge, S
Returning to E6, if UH = 1 and there is a charge, "O" is drawn in the "setting" column of the program, that is, the program having the same program number as the SW number (SE9). Furthermore, the KB indicated by NR
The SW number pressed in R is stored (SE10), BZR is decremented (SE11), and it is determined whether or not BZR = 0 (SE12). And BZR
If ≠ 0, NR is incremented (SE1
3) Return to SE6, and SE6 to S until BZR = 0
The loop of E13 is repeated, and when BZR = 0, the pay program reception setting process is ended. Therefore, for example, the pay program permission number data UBD is “2”, and SW
Assuming that 2 and SW4 are pressed in sequence, as shown in FIG. 20C by the processing of SE9, "program" and "program" are displayed.
"○" is displayed in the "Setting" column of KBR1 = 2, KBR2 = 4 by the process of SE10, and KBR3
= 0, KBR4 = 0, and BZR = 2
-1-1 = 0 is set, and the pay program reception setting process is terminated.

At this time, the value of the "settable number of programs" is displayed as shown in the figure, and the value of the "settable number of programs" changes from 2 to 1 to 0 in the case of this example. The number of programs that can be sequentially set is shown while decreasing the value. Therefore, by visually recognizing this, the setting operation can be performed while recognizing the number of programs that can be set.

On the other hand, the program selection operation processing (SC5)
Is performed according to the flow shown in FIG.
It is determined whether or not ~ 9 has been pressed (SF1), and these SW
If any one of 1 to 9 is pressed, S is further pressed.
It is determined whether the W number is less than or equal to the total number of programs BS (SF
2). If it is less than BS, it is judged whether or not the pay broadcast code UH having the same program number as the SW number is "0" (SF3), and if UH = 0 and it is free, the program is immediately displayed. The display content data of this program is displayed (SF4).
By the processing of SF4, the main program content of the free program (in this example, "program A") stored in the reception data memory area 47a of the RAM 47 is read out and displayed on the display unit 6.

Further, as a result of the discrimination in SF3, if UH = 1 and it is a pay program, it is discriminated whether or not it is the pay broadcast receiving mode (SF5), and if it is the pay broadcast receiving mode. Sets NR to "1" (SF6).
Next, it is determined whether or not the value of KBR indicated by NR is the same as that of the pressed SW (SF7), and if it is the same, the main program content data of the above program is displayed (SF8). But,
If they are not the same, after incrementing NR (S
F9), it is determined whether or not the value of KBR indicated by NR is "0" (SF10). If it is not "0", the process returns to SF7 and "0".
If so, the process proceeds to SF11.

That is, the SW having the same number as the SW operated in the pay program reception setting process described above with reference to FIG.
When is operated, the value of KBR indicated by NR in SF7 becomes the same as the pressed SW number. That is, in the example of the pay program reception setting process of FIG. 18, SW2 and SW4 are sequentially pressed and KBR1 = 2 by the process of SC15,
KBR2 = 4, and KBR3 = 0 and KBR4 =
0 is set. Therefore, if SW2 is operated during this program selection operation processing, KBR1 indicated by NR = 1 is “2” at the time of NR = 1, and the number of SW2 and the value of KBR1 of “2” are indicated in SF7. "Is the same. Therefore, in SF8, the display unit 6 displays the program content of the program number 2, which is "program".

During the program selection operation processing,
When SW4 is operated, at the time point of NR = 2, KBR2 indicated by NR = 2 becomes “4”, and SW at SF7.
The number 4 and the value "4" of KBR2 are the same. Therefore, in SF8, the display unit 6 displays the program content of the program number "program". Therefore, during the program selection operation process, by operating the SW having the same number as in the pay program reception setting process, the content of the pay program which is decided to be viewed in advance can be viewed.

In this example, as described above, KB
Since R3 = 0 and KBR4 = 0 are set,
When NR = 3, KBR3 = 0 indicated by NR = 3
Therefore, the process proceeds from SF10 to SF11. However, even if a certain program number is also stored in KBR3, since "0" is always stored in KBR4, the process proceeds from SF10 to SF11 when NR = 4.

When the value of KBR indicated by NR = 0 and the SW having a different number from the pay program reception setting process is operated, and in the free broadcast reception mode, SF5 is set.
In SF11 subsequent to SF10 and SF10, it is determined whether or not the sample program presence code MB = 1 having the same program number as the SW number (SF11). If MB = 0 and there is no sample program, this program selection operation is performed. When the processing ends and MB = 1 and there is a sample program, the sample program content data of the program is displayed (SF12).

Therefore, by operating the SW having a number different from that during the pay program reception setting process, if there is a sample program in another pay program which is not selected, it can be visually recognized and the IC When the card 2 has expired, if a SW having a number within the total number of programs BS is operated, it is possible to visually recognize a sample program, if any.

Although the IC card is shown as the information storage medium in the embodiments, the present invention is not limited to this, and another medium may be used. In addition, the present invention can be widely applied not only to the mobile FM multiplex broadcasting system but also to a paging system using wireless communication, various communication and broadcasting.

As described above, according to the present invention, the reception control information can be read and stored from the mounted information storage medium. Therefore, even if the information storage medium is not always mounted in the apparatus main body, It becomes possible to control reception of service information. In other words, the receiving device is a multi-functional device that not only receives paid and free service information but also mounts an information storage medium in which various programs are stored to generate functions other than information reception. It is also considered. Therefore, even if the information storage medium is not always attached to the main body of the apparatus, the reception control of the service information becomes possible, so that the billing process based on the reception control information is performed and the information is stored in another storage information medium. It allows the expression of other informed functions.

If the reception control information is information indicating the reception valid period of the pay service information, the period can be managed only by the service information receiving device based on this. Also,
When the reception processing means determines that the information indicating the valid reception period is invalid, the display of the service information is prohibited, so that the unauthorized use of the service information beyond the valid reception period can be prevented. Further, in the configuration including the instructing means, the reception control information stored in the storage medium can be written in the storage means in a timely manner when instructed by the instructing means. Furthermore, when the memory of the storage means is lost, the control means performs rewriting,
The reception control information can be reliably stored and held in the storage means. Further, by writing in the information storage medium that the reception control information is stored in the storage means by the writing means, it is possible to indicate whether or not the information in the storage medium has already been stored. Further, by displaying the storage state of the storage means by the display means, this can be confirmed from the outside.

When the same information storage medium is again attached to the apparatus main body, the information of the storage medium is already stored by the information indicating that the reception control information stored in the information storage medium is stored. You can recognize that you have been done. Therefore, by re-storing the reception control information stored in this information storage medium in the storage means of the apparatus main body, it becomes possible to store the reception control information stored in the information storage medium while updating it. .

Further, in the information storage medium of the present invention,
Since the writing area for writing the information indicating that the control information is stored in the service information receiving device is provided, the information in the information storage medium is already stored in the receiving device by writing in this area. It is possible to identify whether or not there is.
