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: 4-bit data indicating from 1994 to 2010 and 9 bits from 0 to 364 corresponding to 1st to 365th, like the above-mentioned end-of-use data SSYD and end-of-use data SSDD. Data and data. Current year data register GYR: It has a 4-bit structure and stores the current year from 1994 to 2010. Current date data register GDR: 9-bit configuration and stores the current date of 0 to 364 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. Transfer calculation register JZR: Stores the number of days of pay broadcast valid period left on the IC card 2 for transfer from the IC card 2 to another device main body. Program permission calculation register BZR: Stores intermediate data when calculating the program permission number. Allowed program number registers KBR1 KBR2 KBR3 KBR4: KBR1 to KBR1 to 3 store the program numbers 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 section 43 in the service information receiving apparatus 1 is shown in FIG.
The operation is started according to the series of flows shown in 0 to 13,
Monitor the reception of multiple broadcast date data HD (SA
1). 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, the main body transfer end year data HJSY written in the main body transfer end date data writing area 44a of the E2-ROM 44 is compared with the current year data GYR to determine whether or not HJSY <GYR. Yes (SA
3). The main body transfer end year data HJSY indicates the end year of the valid period during which the pay broadcast transferred from the IC card 2 to the service information receiving device 1 side can be received, as described later in SA21 of FIG. 11 and SA40 of FIG. Shows. Therefore, as a result of the determination of SA3, HJSY <G
If there is a relationship of YR, it has passed the end year of the valid period during which the pay broadcast transferred from the IC card 2 to the service information receiving device 1 side can be received, and in this case, without distinguishing SA4 and SA5. , SA6. Also, HJSY <
If there is no GYR relationship, it is further determined whether or not the main body transfer end year data HJSY and the current year data GYR are equal (SA4). As a result of this determination, HJSY ≠ GY
If it is R, it is clear that it is before the end of the transferred effective period and is currently within the transferred effective period, so the pay broadcast receiving mode is set (SA8).

However, if HJSY = 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 (SA5). ). This end date HJSD of the transfer of the main body is also SA21 of FIG. 11 and FIG.
As will be described later in SA40, it indicates the end date of the transfer valid period in which the pay broadcast transferred from the IC card 2 to the service information receiving device 1 side can be received. Therefore, if the comparison result of SA5 is HJSD ≦ GDR, the transfer valid period has already passed, and in this case, SA
Proceed to 6. However, if HJSD> GDR, the pay broadcast reception mode is set because it is before the main body transfer end date (SA8).

If the service information receiving apparatus 1 is used for the first time today after purchase, as described above, E
2-Main body transfer end date data writing area 4 of ROM 44
The date when the service information receiving device 1 is shipped is stored in advance in the main body transfer end year data HJSY and the main body transfer end date data HJSD in 4a. And
The shipping date is always before the user starts using the service information receiving apparatus 1. Therefore, when the use of this service information receiving device 1 is started, SA3 → SA6 or SA3 → SA4 → S
The procedure will be A5 → SA6. Then, in SA6, it is determined whether or not the IC card 2 is mounted in the slot 22, and if it is not mounted, the non-pay broadcasting reception mode is set (SA7).

That is, if today is before the main body transfer end date written in the main body transfer end date data writing area 44a of the E2-ROM 44 and within the transfer valid period, the IC card 2 is mounted. The pay broadcast reception mode is set regardless of whether or not it is present (SA8), and if the transfer expiration date has not passed and the IC card 2 is not installed, the non-pay broadcast reception mode is immediately set (SA).
7).

If the transfer expiration date has passed but the IC card 2 is installed, that is, the determination in SA6 is Y.
In the case of ES, the flow proceeds from SA6 to SA9 in FIG. 11 and determines whether MF = 1. If MF = 1 as a result of this determination, the mounted IC card 2 is an unused one, and this date is the use start date of the IC card 2. Therefore, the current year data stored in GYR is used as EE
-Use start date data writing area 52b of the PROM 52
And the current date data stored in GDR is written in the use start date data writing area 52b as use start date data SKDD (SA1
0).

Next, after setting "0" to the transfer calculation register JZR (SA11), "If you want to transfer, please press the transfer setting SW" is displayed on the display unit 6 (SA
12). Therefore, the user can easily perform the transfer operation by visually recognizing the wording displayed on the display unit 6. Thereafter, the SW waiting state for 5 seconds is maintained (SA13), and if 5 seconds have elapsed, it is determined whether or not the transfer setting SW 91 is pressed (SA1).
4). Then, the user sets the transfer setting S according to the display.
When you press W91, proceed from SA14 to the flow of Fig. 12,
Furthermore, the loop of SA28 → SA29 → SA28 is repeated until either the deadline reduction SW92 or the confirmation SW93 is pressed.

When the user presses the deadline reduction SW 92 while waiting for repeating this loop, the value of the transfer calculation register JZR is incremented (SA30). In addition,
This transfer operation register JZR is used to transfer the IC card 2 from the IC card 2 to another device body as described above.
The number of days of the pay broadcast valid period left on the card 2 is stored. Then, in the next SA31, whether or not the value of this incremented JZR becomes UD-1, that is, the value of JZR becomes the remaining valid period obtained by subtracting “1” for today from the valid period relative value data UD. It is determined whether or not (SA31). Then, if the result of this determination is that JZR <UD-1, it returns to SA28 and enters the standby state by the loop. Therefore, when the transfer setting SW 91 is pressed and then the deadline reduction SW 92 is pressed, JZ is executed by the processing of SA 30 each time the deadline reduction SW 92 is pressed.
The value of R increases.

Then, when the user presses the expiration date reduction switch SW92 until JZR = UD-1, all the number of days is changed except for one day (today) of the effective period set in the IC card 2. The value is left to be transferred to the apparatus body, and the value of JZR cannot be increased any more. Therefore, in such a case, the operation returns from SA31 to SA15 in FIG. 11 without waiting for the operation of the confirmation SW 93.
Also, within the validity period of the IC card 2, any number of days is left to be transferred to another device body, and the JZR is still left.
<If it is in the UD-1 state, the process returns from SA29 to SA15 when the confirmation SW 93 is pressed. That is, the user presses the transfer setting SW 91, then presses the deadline reduction SW 92 a desired number of times, and then presses the confirmation SW 93 to set an arbitrary number of days corresponding to the number of times the deadline reduction SW 92 is pressed (however, within UD-1). ) Can be left for transfer to another service information receiving apparatus 1, and the number of days for transferring to this remaining service information receiving apparatus 1 is indicated by JZR. And SA14, SA
In SA15 of FIG. 11 following 29 and SA31, EE-P
The validity period relative value data UD is read from the validity period relative value data storage area 52a of the ROM 52, the validity period relative value data UD is added to the current date data stored in the GDR, and the transfer calculation register JZR is added. Is subtracted and the value is stored in the date calculation register HZR (SA15).

That is, "UD + JDR" is obtained by adding the value of the validity period relative value data UD of the IC card 2 to the GDR storing the current month / day data indicating today.
The end date of use of the IC card 2 (validity period expiration date) is obtained starting from today. In addition, since the JZR stores data indicating the number of days of the pay broadcast valid period left for transfer from the IC card 2 to the other device main body, "UD + JDR-JZR" indicates that the other device Data indicating the effective period after deducting the transfer to the main body is obtained, and data indicating the end date of the effective period is stored in the HZR. Of course, immediately after the IC card 2 is started to be used and the transfer setting of SA28 to SA31 is not performed, the JZ processing is performed by the processing of SA11.
Since R = 0, UD + JDR is stored in HZR.

Subsequently, it is determined whether or not the value of HZR is 364 or less (SA16). Here, if the value of HZR is 364 or less, even if the value of "year" is not advanced,
The end year and date can be indicated by the values of GYR that stores the current year data and HZR that stores the valid period end date data. Therefore, in this case, the current year data stored in the GYR is used as it is as the use end year data SSYD, and the use end date data writing area 5
2c (SA17) and, at the same time, write the end-of-validity-date data stored in the HZR as SSDD in the end-use-date data writing area 52c (SA
18).

However, as a result of the determination in SA16, HZR
If the value of is greater than 364, the end-of-use date cannot be represented by a numerical value of 0 to 364 corresponding to 1 to 365 days unless the value of “year” is advanced. So GYR
The value of the current year data stored in is incremented, and the incremented value is used
It is written as YD in the use end date data writing area 52c (SA19). Subsequently, 364 is subtracted from the valid period end date data stored in the HZR, and the value is written as the use end date data SSDD in the use end date data writing area 52c (SA20).

SA following SA18 and SA20
21, the SSYD value and the SSDD value are set as the main body transfer end year data HJSY and the main body transfer end date data HJS.
As D, it is written in the main body transfer end date data writing area 44a of the E2-ROM 44. Therefore, this SA2
When the process from SA1 is repeatedly executed by executing the process of No. 1, SA3 to S3 of FIG.
In A5, HJSY <GYR (SA3 is YES),
Alternatively, the pay broadcast reception mode (SA8) is continuously set until HJSY = GYR and HJSD ≦ GDR (both SA4 and SA5 are YES). That is, from the valid period stored in the IC card 2, the above SA28-
In SA31, the remaining valid period after subtracting the valid period left for the transfer to another device main body becomes the pay broadcast receivable period of the service information receiving device 1 in which the IC card 2 is mounted. .

At SA22 following SA21, it is determined whether or not the transfer operation register JZR = 0. If JZR = 0, the effective period for transferring to another apparatus main body is not left, The unused flag MF is set to "2" to indicate that the use of the IC card 2 is prohibited. However, if JZR ≠ 0, the valid period is left to be transferred to another device main body, so the value of JZR that stores the remaining valid period is set to the IC
As the new validity period relative value data UD of the card 2, E
E-PROM 52 effective period relative value data storage area 52
In addition to writing to a (SA23), the unused flag MF is set to "0" to indicate that there is a transfer right (SA2).
4). And SA26 following SA24 and SA25
Then, the pay broadcast reception mode is set, the pay program reception setting process (SA27) described later is executed, and the process returns to SA1.

On the other hand, if the result of determination in SA9 is that the unused flag MF ≠ 1, it is further determined whether or not MF = 2 (SA32). Here, the unused flag M
Since F is a value of 0, 1 or 2, if both the determinations of SA9 and SA32 are NO, it means that MF = 0 and that the mounted IC card 2 has the transfer right. There is. When MF = 0 and the transfer right is present, the process proceeds from SA13 to the flow of FIG. Therefore, the processes of SA34 to SA43 shown in FIG. 13 are (1) mounted on another device main body and started to be used.
When the IC card 2 having the transfer setting shown in (4) is removed from the other device main body and attached to this device main body, (2) the IC card 2 is attached to this device main body to start use. When the IC card 2 having the transfer setting shown in FIG. 12 is removed from the apparatus main body and the same IC card 2 is attached to the same apparatus main body again, this is executed. The usage example of (2) is
The IC card 2 for 6 months is left for 4 months by the transfer setting, only 2 months are used, and after 2 months, the same IC card 2 is attached to the same device body and left. This is the case where the four months worth is transferred and used from now on.

That is, first, the current year data stored in the GYR is set as the transfer start year data JKYD, and EE
-A transfer start date data writing area 52f of the PROM 52
And the current date data stored in the GDR as the transfer start date data JKDD in the transfer start date data writing area 52f (SA3).
4). Next, the effective period relative value data UD is read from the effective period relative value data storage area 52a of the EE-PROM 52, and the effective period relative value data UD is added to the current date data stored in the GDR. The value is stored in the date calculation register HZR (SA35). Here, the effective period relative value data UD does not indicate the original effective period of the IC card 2, but is a value written in SA23 described above.

Subsequently, it is determined whether or not the value of HZR is 364 or less (SA36). Here, if the value of HZR is 364 or less, even if the value of "year" is not advanced,
The transfer end date can be indicated by the current year and the current month date + effective period relative value data. Therefore, in this case GY
The current year data stored in R is directly written as the transfer end year data JSYD in the transfer end date data writing area 52g (SA37), and the “current month date + effective period relative value data” stored in the HZR is also stored. Is written in the transfer end date data writing area 52g as the transfer end date data JSDD (SA38).

Subsequently, the transfer end year data JSYD and the transfer end date data JSDD are set as the main body transfer end year data HJSY and the main body transfer end date data HJSD, respectively.
The data is written in the main body transfer end date data writing area 44a of the E2-ROM 44 (SA41). Through the above processing, all the valid period remaining in the IC card 2 is transferred to the apparatus main body side, and the valid period remaining in the IC card 2 can be used without waste. Further, as a result, the IC card 2 has no remaining effective period, so "2" is written in the unused flag MF (S
A42), after disabling this IC card 2,
The pay broadcast reception mode is set (SA43).

As a result of the determination in SA36, when 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 the incremented value is used as the transfer end year data JS.
The data is written as YD in the transfer end date data writing area 52f (SA39). Subsequently, 364 is subtracted from the value stored in the HZR, and the value is set as the transfer end date data JSDD, and the transfer end date data writing area 52.
Write to f (SA40). After that, the above-mentioned SA
The processes of 41 to SA43 are performed, and the process returns to SA1.

In this embodiment, the deadline reduction SW
According to the number of operations of 92, the number of days of the valid period to be transferred to another device main body is specified, and the remaining number of days after subtracting the specified number of days is transferred to the device main body. It is also possible to specify the number of days of the valid period to be transferred to the apparatus main body by the number of operations of the expiration date reduction SW 92, and transfer the remaining number of days after subtracting the specified number of days to another apparatus main body.

On the other hand, as a result of the determination in SA32, the unused flag MF = 2, and the mounted IC card 2
Is prohibited, the non-paid broadcast receiving mode is set (SA33) and the process returns to SA1. That is, if the determination of SA6 is YES and the IC card 2 is mounted in the slot 22, the valid period does not remain in the IC card 2 and the unused flag is "2". The non-pay broadcast receiving mode is set without setting the pay broadcast receiving mode.

On the other hand, the reception processing section 43 is the same as that shown in FIGS.
The processing shown in FIG. 14 is executed in parallel with the processing shown in FIG. That is, the reception of HI, which is the ID indicating the program guide, is monitored (SC1), and when the HI is received, the program guide data is fetched (SC2) and the program selection screen creation processing (SC3) described later is executed. Then, the program content data is fetched (SC4), the program selection operation process (SC5) described later is executed, and the process returns to SC1.

The program selection screen creating process (SC3) is as follows.
This is performed according to the flow shown in FIG. 15, and after drawing table items and frames (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” column to indicate “program a” to “program” as shown in FIG. 18 (A). 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. 18A, 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 reception 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
Is stored). At this time, the program numbers that are decided to be viewed with pay are stored in order from KBR1.
"0" is always stored in the KBR4.

Therefore, first in SD9, NR = 1 is set, then in SD10, the shaded portion 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, SD10 to SD1
The loop of 4 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. 18B, 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. 11).
SA27) is performed according to the flow shown in FIG. 16, 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 the initial value "1" is set in 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 it is free, 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
If 2 and SW4 are pressed in sequence, the process of SE9 causes "program" and "program" as shown in FIG. 18 (C).
"○" 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.

The program selection operation process (SC5) is shown in FIG.
This is performed according to the flow shown in 7. That is, the above S
It is determined whether or not W1 to 9 are pressed (SF1), and if any of these SW1 to 9 is pressed, it is further determined whether or not the pressed SW 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 contents of the free program (in this example, "program A") stored in the reception data memory 47 are 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. 16, SW2 and SW4 are sequentially pressed and KBR1 = 2, K by the process of SC5.
BR2 = 4, KBR3 = 0, 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.

Then, 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 different number from that during the pay program reception setting process, if there is a sample program in another pay program which is not selected, it is possible to visually recognize it and at the same time, the IC When the valid period transferred from the card 2 to the apparatus main body has expired, the SW having a number within the total number of programs BS can be operated, and if there is a sample program, it can be visually recognized freely.

In the embodiment, the valid period stored in the IC card 2 is divided and transferred, but it may be divided into three or more and transferred. Further, in the embodiment, the information storage medium I
Although the C card is shown, the medium is not limited to this, and another medium may be used. In addition to being applied to a mobile FM multiplex broadcasting system, the present invention can be widely applied to a wide range of paging systems that use wireless communication and various types of communication and broadcasting.
