Next, the operation of the transmitting / receiving apparatus 1 will be described with reference to the flowcharts shown in FIG. In the flow, the following data and registers are used. Date data HD: Like the end-of-use date data SSYD and end-of-use date data SSDD, the date from 1994 is 2
4-bit data indicating the year 010 and 365 from 1 day
9-bit data of 0 to 364 corresponding to the day. Current year data register GYR: 4-bit configuration and 1
The current year from 994 to 2010 is stored. Current month / day data register GDR: Stores the current month / day of 0 to 364 corresponding to 1 to 365 days, having a 9-bit configuration. (Note that GR indicates both GYR and GDR registers.) Date calculation register HZR: Stores intermediate data when calculating the use end date. Expiration register KGR: “0” indicates expiration and “1” indicates expiration. Function register KR: "1" indicates a request, "2" indicates a quiz, and "3" indicates a lottery program. Fraction calculation register HSR: Stores the accounting unit fraction. Program permission calculation register BZR: Stores intermediate data when calculating the number of permitted programs. Permitted program number registers KBR1, KBR2, KBR3, KBR4: KBR1 to KBR3 store the program number determined to be paid and visually recognized, and KBR4 always stores "0". Increment register NR: stores a value for specifying KBR1 to KBR4.

That is, the transmission / reception processing unit 43 in the transmission / reception apparatus 1 starts operating according to a series of flows shown in FIGS. 11 to 13 with the power-on, and responds to the power-on. Is set (SA1), and reception of the date HD is monitored (SA2). And
When the date data HD is received from the transmission signal having the format described above, the date data HD is stored in the GR. Here, GR is GYR and GD as described above.
Since both the R and R registers are indicated, of the received date data HD, the 4-bit current year data is stored in the current year data register GYR, and the 9-bit current month data is stored in the current month data register GDR. (SA
3).

Next, the reception of the HI, which is the ID indicating the program table, is monitored (SA4). If the HI is received, the program table data is fetched (SA5), and a program selection screen creation process (SA6) described later is performed. Execute Further, program content data is continuously taken in (SA7), and a program selection operation process (SA8) described later is executed. Next, it is detected whether or not the IC card 2 is inserted in the slot 22 (SA9),
If it is not mounted, 1 is set in the register KGR (SA10), and the process returns to SA2.

When the IC card 2 is inserted into the slot 22, the state of the flag MF stored in the IC card 2 is read to determine whether MF = 1 (SA11). . As a result of this determination, MF = 1
If the IC card 2 is unused, this date is the use start date of the IC card 2. Therefore,
The current year data stored in GYR is written as usage start date data SKYD in the usage start date data writing area 52b of the EEPROM 52, and the current month / day data stored in GDR is used as usage start month / date data SKDD. , The use start date data writing area 5
2b (FIG. 12 SA12).

Next, the valid period relative value data UD is stored in the valid period relative value data storage area 52a of the EEPROM 52.
Is read, and the valid period relative value data UD and GDR
Is added to the current month and day data, and the value is stored in the date calculation register HZR (SA13). Subsequently, it is determined whether or not the value of HZR is equal to or less than 364 (SA14). Here, if the value of HZR is equal to or less than 364, the use end date can be indicated by the current year and the current month / date + valid period relative data without increasing the value of “year”.

Therefore, in this case, the current year data stored in the GYR is used as it is, and the use end year data SSY is used.
D is written into the use end date data writing area 52c (SA15), and the “current month + effective period relative data” stored in the HZR is used as the use end date data SSDD, and the use end date data write area 52c is written.
Write to c (SA16). Thereafter, a flag M is set to indicate that the IC card 2 has been used.
After resetting F (SA19), KGR is reset (SA20), indicating that the IC card 2 is within the expiration date, and subsequently, a pay program reception setting process (SA21) described later is executed. Return to SA2.

However, as a result of the determination in SA14, HZR
Is greater than 364, the use end date cannot be represented by a numerical value from 0 to 364 corresponding to the 1st to 365th days unless the value of “year” is advanced. So, GYR
Is incremented by the value of the current year data stored in the
It is written in the use end date data writing area 52c as YD (SA17). Subsequently, 364 is subtracted from “current month / day + valid period relative data” stored in the HZR, and the value is written as end-of-use date data SSDD in the end-of-use data write area 52c (SA1).
8). Thereafter, the processing of SA19 to SA21 described above is performed, and the process returns to SA2.

On the other hand, if the result of the determination at SA11 is that MF = 0, this IC card 2 has already been used. Then, when the use has been started, first, the use end year data SSYD is compared with the current year data stored in GYR to determine whether or not SSYD ≦ GYR (SA22 in FIG. 13). As a result of this determination, S
Unless YD ≦ GYR, the IC card 2
Is not expired, so that "0" is set in the expiration register KGR to indicate that it is within the validity period (SA25), and then the process returns to SA2.

When SSYD ≦ GYR in SA22, the use end year data and the current year data may coincide. Therefore, next, the use end date data SSDD is compared with the current date data stored in the GDR to determine whether SSDD ≦ GDR (S
A23). If SSDD is not equal to or less than GDR as a result of the determination, the IC card 2 is within the expiration date, so "0" is set in the expiration register KGR to indicate that it is within the expiration date (SA25). However, S22
SYD ≦ GYR and SSD23 ≦ G in SA23
In the case of DR, since the IC card 2 has already expired, it sets “1” in KGR to indicate that it has expired (SA24), and then returns to SA
Return to 2.

The program selection screen creation processing (SA6)
This is performed according to the flow shown in FIG. 14, and after drawing table items and frames (SB1), the program names of BM1 to BM are displayed (S1).
B2). By the processing of SB1 and SB2, FIG.
As shown in (A), the display section 6 displays “program name” and “paid”.
Frame is displayed along with the table item of "sample program", "Send billing". Subsequently, “〇” is drawn in the “pay” column of the program with the pay broadcast code UH = 1 (SB3), and “〇” is drawn in the “sample program” column of the program with the sample program presence / absence code MB = 1. (SB4).

Next, it is determined whether or not the charging type of each program is KS = 0 (SB5). If KS = 1 and the program is to be charged for reception, the process of SB6 is performed. The process proceeds to SB7 without any further processing. Also, when a program of interest for transmission charging a KS = 0 draws a The symbol "" in "Send billing" column of the program (SB6). Therefore, for example, assuming that the received signal has the data shown below and shown in FIG. 9, as shown in FIG. ”Is displayed, and“ 〇 ”is displayed in the“ paid ”column corresponding to“ programs ”to“ programs ”, and“ samples ”and“ programs ”are displayed in the“ sample programs ”column. with "〇" is displayed Te, is to "transmit billing" column and is displayed that corresponds to the "program e" - "program ki""〇".

BS = 7 BM = program, UH = 0, MB = 0, BB = 1 BM = program, UH = 1, MB = 0, KS = 1, BB = 2 BM = program, UH = 1 , MB = 1, KS = 1, BB = 3 BM = program, UH = 1, MB = 1, KS = 1, BB = 4 BM = program, UH = 1, MB = 0, KS = 0, BB = 5 BM = program or UH = 1, MB = 0, KS = 0, BB = 6 BM = program, UH = 1, MB = 0, KS = 0, BB = 7 Further, SB7 following SB5 and SB6 Then, it is determined whether or not the expired register KGR = 1.
Since R is initially set in SA1 of FIG. 11, KGR = 1 at the time of startup, so that the “pay” column of the program with the pay broadcast code UH = 1 is shaded (SB8), UH = 1 and sample program presence / absence code M
The "program name" column of the program with B = 0 is shaded (SB9).
By the processing of SB8 and SB9, as shown in FIG. 19A, "program name", "program name" to "program name" column and "program name" to "program name" Shading is displayed in the “paid” column. In other words, the shaded "program name" column, it is no sample program pay program, and with it a program is shown as a transmission target of the signal <br/> billing,
Shading in the “paid” column indicates that the program is a paid program that cannot be displayed. If KGR = 0 and the IC card 2 is within the time limit as described later,
The process proceeds from B7 to SB10, and shades the "pay" column of the program with the pay broadcast code UH = 1 (SB10). Next, it is determined whether or not the charging type KS of each program is 0 (SB11).
If a KS = 0 is a program to be subjected to the transmission billing, turn off the shading of the "pay" column of the program which is the "〇" drawing in "Send billing" column of the program ( SB1
2). By the process of SB12, as shown in FIG. 19 (B), shading in the “pay” column of “program” to “program” disappears.

Further, SB following SB11 and SB12
In 13, after setting “1” to NR, the shading in the “paid” column of the KBR value indicated by this NR is erased (SB1).
4). Here, the permitted program number register KBR is composed of KBR1 to KBR4 as described above, and includes a program number determined to be paid for viewing by a process described later (any one of 2 to 4 in this example). ) Is stored. At this time, the program numbers determined to be paid and viewed are stored in order from KBR1, and "0" is always stored in KBR4.

Therefore, first, at SB13, NR = 1 is set, and at SB14, the shading in the "pay" column of the program number corresponding to the value of KBR1 is erased. Indicates that it is selected. Next, it is determined whether or not the sample program presence / absence code MB of the program having the value of KBR1 is 1 (SB15).
If it is 1, and there is a sample program, the "sample program" column corresponding to this program is shaded (SB16). This indicates that the viewing of the sample program is unnecessary because this program has been selected for pay viewing. Continue with NR
Is incremented (SB17), it is determined whether or not the value of the KBR indicated by the incremented NR is “0” (SB178). If not, SB14 is determined.
If the value is "0", the program selection screen creation processing ends.

Therefore, for example, if any of the values “2” to “4” is stored in all of the KBRs 1 to 3, the loop of SB14 to SB16 is repeated three times, and NR = 4 At this time, since KBR4 is always "0", the process proceeds from SB18 to the stop processing. In addition, for example, “MB2 = program” and “MB
4 = program ”(this“ MB4 = program ”is a sample program)
Is selected in advance, the loop is repeated twice, and as shown in FIG. 19B, “3.
Are shaded in the "paid" column of ".", And are shaded in the "sample program" column of "4. That is, the shaded “pay” column indicates that the program is not selected, and the shaded program in the “sample program” column indicates that the pay program is selected, and the sample program cannot be displayed. Is shown.

On the other hand, the pay program reception setting processing (SA2
1) is performed according to the flow shown in FIG.
After the frame is drawn (SC1), the program names of BM1 to BM are displayed (SC2), and the pay broadcast code UH = 0 (free)
And KS = 0 (transmit billing) to shaded "program name" and "Settings" section of (SC3). By the processing of SC1 to SC3, table items and frames of “program name” and “setting” are displayed on the display unit 6 as shown in FIG. 19C, and “program a” to “program a” are displayed in the “program name” column. along with the "program-out" is displayed, shaded is displayed in a free program is a "program a" and transmit billing program "program you" - "program ki". This allows
The pay programs “programs” to “programs” to be selected are unshaded to clarify.

Next, the value (one of 1 to 3) of the pay program permission number data UBD is stored in the program permission calculation register BZR (SC4), and the initial value "1" is set in NR (SC5). It is determined whether or not SW1 to SW9 has been pressed (SC6). Here, SW1 to SW9 are keys corresponding to "1" to "9" of the hiragana / number input key group 11 when the character / number selection key 9 shown in FIG. is there. If any one of these SW1 to SW9 is pressed, the pressed SW number is the total number of programs B
It is determined whether it is less than S (in this example, BS = 7 as described above) (SC7), and if it is not less than BS, the process returns to SC6. If it is less than the BS, it is determined whether or not the pay broadcast code UH of the same program number as the SW number is "1" (SC10).

If UH = 0 and free, S
Returning to C6, if UH = 1 and the fee is charged, further S
It is determined whether or not KS = 1 of the same program number as the W number (S
C9). As a result of this determination, if KS = 1 and the program is to be charged for reception, the program, that is, S
"@" Is drawn in the "setting" column of the program having the same program number as the W number (SC10). Further, the pressed SW number is stored in the KBR indicated by NR (SC11), and after decrementing the BZR (SC12), it is determined whether or not BZR = 0 (SC13). If BZR ≠ 0, NR is incremented (SC14), and SE6
Then, the loop of SC6 to SC14 is repeated until BZR = 1, and when BZR = 0, the pay program reception setting processing ends. Therefore, for example, if the paid program permission number data UBD is “2” and SW2 and SW4 are sequentially pressed, the process of SC14 in FIG.
As shown in (C), “〇” is displayed in the “Setting” column of “Program” and “Program”, and KB is processed by SC15.
R1 = 2, KBR2 = 4, and KBR3 = 0,
While KBR4 = 0, BZR = 2-1-
When 1 = 0, the pay program reception setting process ends.

At this time, the value of the "number of settable programs" is displayed as shown in the figure, and the value of the "number of settable programs" changes from 2 to 1 to 0 in this example. This shows the number of programs that can be sequentially set 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 (SA9)
Is performed according to a series of flows shown in FIGS.
It is determined whether or not the above-mentioned switches SW1 to 9 have been pressed (SD
1) If any one of these SW1 to 9 is pressed,
Further, it is determined whether the pressed SW number is less than the total program number BS (SD2). If it is less than BS, it is determined whether or not the pay broadcast code UH of the same program number as the SW number is “0” (SD3). Display processing of this program content data (SD4). Through the processing of SD4, the main program contents of the free program (“program a” in this example) stored in the memory area of the reception data memory 47 are read out, and the display unit 6
Will be displayed.

If it is determined in SD3 that UH = 1 and the program is a pay program, it is further determined whether or not there is a charging type KS = 0 of the same program number as the SW number (SD
4) If KS = 0 and the program is to be charged for transmission, the process proceeds to SD14 in FIG. Also, KS
= 1 and the program to be charged for reception, it is determined whether the expiration register KGR is "1", that is, whether the IC card 2 has expired or is not installed in the slot 22. Determine (SD6), KGR
If = 0 and within the expiration date, "1" is set to NR (SD7). Next, it is determined whether or not the value of KBR indicated by NR is the same as the pressed SW (SD8), and if it is the same, the main program content data of the program is displayed (SD9). However, if they are not the same, after incrementing NR (SB10), it is determined whether the value of the KBR indicated by NR is "0" (SD11). If not, the process returns to SD8 and returns to "8". If so, proceed to SD12.

That is, the SW having the same number as the SW operated in the pay program reception setting processing described above with reference to FIG.
Is operated, the value of KBR indicated by NR in SD8 always becomes the same as the pressed SW number. That is, in the example of the pay program reception setting process of FIG. 15, SW2 and SW4 are sequentially pressed, and KBR1 = 2 by the process of SC15.
KBR2 = 4, and KBR3 = 0, KBR4 =
0 is set. Therefore, when SW2 is operated during this program selection operation processing, at the time of NR = 1, KBR1 indicated by NR = 1 is "2", and the number of SW2 and the value of KBR1 "2" in SD8. Is the same as Therefore, in SD9, the program content of “program I” of program number 2 is displayed on the display unit 6.

During the program selection operation processing,
When SW4 is operated, at the time of NR = 2, KBR2 indicated by NR = 2 is “4”, and SW8 is
The number 4 and the value “4” of KBR1 are the same. Therefore, in SD9, the program content of “Program No.” which is the program number 4 is displayed on the display unit 6. Therefore, during the program selection operation process, by operating the SW having the same number as that at the time of the pay program reception setting process, it is possible to visually recognize the content of the pay program that has been determined to be visually recognized in advance.

In this example, as described above, KB
Since R3 = 0 and KBR4 = 0 are set,
When NR = 3, KBR3 = 0 indicated by NR = 3
Then, the process proceeds from SD11 to SD12. However, even if a program number is also stored in the KBR3, since "0" is always stored in the KBR4, the process proceeds from SD10 to SD11 when NR = 4.

When the value of the KBR indicated by the NR = 0 and the SW having a different number from that at the time of the pay program reception setting processing is operated, and when KGR = 1 and the IC card 2 has expired, SD1 following SD6 and SD11
In step 2, it is determined whether the sample program presence / absence code MB = 1 of the same program number as the SW number is set (SD12), and MB = 0.
If there is no sample program, the program selection operation process is terminated. If MB = 1 and there is a sample program,
Display processing of sample program content data of the above program (SD1
3).

Therefore, by operating the SW having a different number from that of the pay program reception setting process, if there is a sample program among the other pay programs for which no program is selected, the sample program can be freely visually recognized, and the IC program can be visually recognized. When the card 2 has expired, if a SW having a number within the total number BS of programs is operated, if there is a sample program, the sample program can be freely visually recognized. In addition, as a result of viewing the sample program, if the user determines that it is necessary to view the contents of the program, the user will purchase a new IC card 2. Purchase frequency can be increased.

On the other hand, as a result of the determination in SD5, if KS = 0 of the same program number as the SW number, it is determined whether or not the program of the program number is an ID indicating a quiz program (FIG. 17).
SD14) If the ID is a quiz program, a value "2" indicating that the program is a quiz program is set in the function register KR (SD15), and then the main program content data display processing of the quiz program and the quiz-related processing are performed. Execute (SD1
6). By the process of SD16, the quiz program title to option 3 data shown in FIG. 10 are displayed on the display unit 6, and the number of the option selected by the user through key operation is fetched.

If the program with the program number is not an ID indicating a quiz program, it is further determined whether or not the ID is an ID indicating a lottery program (SD17).
In the case of, the value "3" indicating the lottery program is set in the function register KR (SD18), and then the main program content data display processing of the lottery program and the lottery-related processing are executed (SD19). By the processing of SD19,
The lottery program title shown in FIG. 10 and comment data from a station explaining the procedure by which the user can participate in this lottery program are displayed on the display unit 6 and set by the user through key operations. The lottery number that was completed is imported.

If the program with the program number is not an ID indicating a quiz program or a lottery program, it is determined that the program is a request program (SD20), and the function register KR indicates that the program is a request program. After setting the indicated value "1" (SD21), the main program content data display processing of the requested program and the request-related processing are executed (SD22). By the processing of SD22, FIG.
In addition to the request program title shown in FIG. 0 and comment data from the station explaining the procedure in which the request is made, the display unit 6 displays the requested music title input by the user through key operation. . When the title of the requested song to be selected is displayed on the display unit 6, the requested song title selected by the user through key operation from among them is captured.

In the flow of FIG. 18 following SD16, SD19 and SD22, the IC card 2
Is determined (SD23), whether KGR = 1 or not (SD24), and the IC card 2 is inserted into the slot 22.
Is not attached, or if KGR = 1 and the IC card 2 has expired, the function register KR is reset (SD25), and this program selection operation process ends.

If the IC card 2 is inserted in the slot 22 and the IC card 2 has not expired, the condition (SD2
6) It is detected whether the function register KR = 2 (SD27) or KR = 3 (SD29). When KR = 2 and the processing of the quiz program is performed, the charging unit fraction HSD currently written in the charging unit fraction writing area 52f is added to the charging unit data KHD of KH2 (quiz). Then, the value is stored in the fraction calculation register HSR (SD28).

When KR = 3 and the lottery program is processed, the process proceeds from SD27 to SD29 to SD30, and the charging unit fraction writing area 52f is stored in the charging unit data KHD of KH3 (lottery). Is added and the value is stored in the fraction calculation register HSR (SD30). Further, KR =
1, if the request program has been processed,
Proceed in the order of SD27 → SD29 → SD31 → SD32, and KH
The accounting unit fraction HSD currently written in the accounting unit fraction writing area 52f is added to the 1 (request) accounting unit data KHD, and the value is similarly stored in the fraction calculation register HSR (SD32).

Then, in SD33 following SD28, SD30 and SD32, it is determined whether or not this fractional operation register HSR ≧ 8.
Is subtracted, and the value is written as the charging unit fraction HSD in the charging unit fraction writing area 52f (SD34). Next, it is determined whether or not the date data SSDD is "0" (SD36). If SSDD = 0, the year data SSYD is decremented, and then the period value "364" is written as SSDD ( SD39) Then, a predetermined data transmission process (SD40) is executed. Also, SD3
