2. Description of the Related Art In digital broadcasting, program information relating to a program to be broadcast is transmitted, and a display reservation or a recording reservation is made by designating a program using a program table created by a receiving apparatus based on the program information. It can be carried out. Therefore, even if the scheduled broadcast time of the reserved program is changed, the receiving apparatus can update the reservation following the changed time of the reserved program based on the changed program information.

[0003] In digital broadcasting, there are specific services such as PPV (pay-per-view) programs and copy guard programs. The PPV program cannot be displayed or reserved unless the intention of purchasing the PPV is indicated beforehand, and the copy guard program can be displayed but cannot be recorded. The fact that these are PPV programs and copy guard programs is described in the program information.

Therefore, when a PPV program is designated for reservation in the program table, the receiving apparatus prompts the user to indicate his / her intention to purchase the PPV program. By indicating that recording cannot be performed when a recording reservation is specified, it is possible to cope with the reservation purchase of a PPV program and restrictions on reservation for a copy guard program.

In a conventional video, a specific program is designated by designating a reservation date and a reservation time zone, and a reservation key is designated every day to designate a reservation time zone. By selecting a reservation key every week and designating a reserved day of the week and a reserved time period for a program to be broadcast in a band, it is possible to make a reservation for recording a program to be broadcast every week in a designated time period on the designated day of the week.

It consists of five members, a start time and an end time. The service ID (channel) on which the program is broadcast, the event ID of the broadcast program, the date on which the program starts broadcasting, and the broadcast of the program are started. And the time at which the broadcast of the program ends.

The input reservation data structure is reservation data which is set by a user inputting from the outside with a remote controller or the like.
D, and specify the date and time zone for which you want to make a reservation,
When the reservation date, reservation start time, reservation end time, and the scheduled broadcast time of a program to be broadcast in the specified time zone are changed, whether to update the reservation according to the changed time zone It consists of five members of follow-up information that specifies

Further, the program-specific reservation data structure is created from the reservation data set by the user and the program information of all programs in the time zone of the reservation data.
That is, it is created from members of the input reservation data structure and the SI program data structure relating to the program in the time zone from the reservation start time to the reservation end time of the input reservation data structure. Service I shown in FIG.
D, the input reservation date, the input reservation start time, the input reservation end time, and the follow-up information are respectively the service ID, the reservation date, the reservation start time, the reservation end time, and the follow-up information of the input reservation data structure. Equivalent to.

The event ID, shown in FIG.
The date MJD, start time, and end time are each S
In the I program data structure, the event ID, the date MJD, the start time, and the end time of the program in the time zone from the reservation start time to the reservation end time of the input reservation data structure are described for each event ID. It is extracted. The reservation start time and the reservation end time indicated by b are compared with the extracted start time and end time, and the input reservation start time and the input reservation end time, and the time at which the reservation is actually started and the time at which the reservation is actually ended. Member calculated as time.

Next, the operation of the broadcast receiving apparatus according to the first embodiment of the present invention for following the reservation time after the date and time reservation will be described with reference to FIGS. First, when a user inputs a channel and a time zone to be reserved to a remote controller or the like by key operation, the input analysis unit 13 interprets the input key to obtain reservation data, and stores the reservation data in an input reservation data structure. Output in the form of a body. Then
The EPG control unit 14 outputs the information of the input reservation data structure from the input analysis unit 13 to the OSD display unit 26,
D display unit 26, along with the contents of the input reservation data structure,
A screen is displayed on which a message for prompting the user to select whether or not the user wants to follow the reserved time is created.

Next, the OSD display unit 26 creates a display screen according to the instruction of the EPG control unit 14 and outputs the display screen to the NTSC encoder unit 25. Next, the NTSC encoder unit 25 encodes the display screen data created by the OSD display unit 26 and outputs it as an NTSC standard video signal, and the created screen is displayed. Here, the user checks the reservation contents (service ID, reservation date, reservation start time, reservation end time) from the screen, and selects whether or not the user wants to follow the reservation time using a remote controller or the like. That is, from the program information transmitted after the reservation, the program to be broadcast in the reserved time zone can be known. Thereafter, when the scheduled broadcast time zone of the program is changed, the reservation is made according to the changed time zone. Select whether to update. For example, the user wants to reserve a program that is broadcast on the same channel at the same time zone every week for the broadcast several weeks ahead, but if the program information several weeks ahead has not arrived, Because the previous program guide cannot be displayed, the channel and time zone (1
5: 30-17: 30) and make a reservation,
The user selects whether or not the user wants to follow the reserved time (see FIG. 3). Next, the input analysis unit 13 interprets the key input to the remote controller or the like, determines whether or not the reservation time tracking is selected, and outputs the determination result. Next, the EPG control unit 14 adds the judgment result (whether or not to follow the reservation time) to the members of the input reservation data structure and adds the reservation setting unit 15
Output to Next, the reservation setting unit 15 stores the input data structure from the EPG control unit 14 into the input reservation data storage unit 1.
Save to 6. Next, the reservation data creation unit 17 is, for example, a handler that is activated once a day, and stores in the SI program data storage unit 12 an SI program data structure corresponding to the input reservation data structure stored in the input reservation data storage unit 16. Check if the body has accumulated. That is, the program information of the time zone set by the user is acquired, and the process waits until the SI program data structure created from the program information is stored. Then, the SI data including the program information of the reserved time zone is transmitted by being superimposed on the digital radio wave, and received from the tuner unit 21 and demodulated by the QPSK unit 22 from the signal.
The SI data is separated by the demultiplexing unit 23 and output to the SI management unit 11.

Next, the SI management unit 11
The EIT data of the I data is analyzed, an SI program data structure is created from the EIT data, and stored in the SI program data storage unit 12. Next, the reservation data creation unit 17
In the I program data storage unit 12, an input reservation data storage unit 16
Corresponding to the input reservation data structure stored in the
After confirming that the program data structure has been stored, the reservation date, reservation start time, and reservation end time of the input reservation data structure, and the SIs of all programs in the time zone
A program-specific reservation data structure is created from the program data structure and stored in the program-specific reservation data storage unit 18.

For example, as shown in FIG. 3, when a user designates a time period of 15:30 to 17:30 and makes a reservation, and program information (before update) of the reserved time period is transmitted,
In the program-specific reservation data structure, the event ID, start time, end time, reservation start time, and reservation end time shown in FIG. Enters. That is, in the first b, the event ID of the program A and the start time (1
5:00), the end time of program A (16:00), the reservation start time (15:30) input by the user, and the end time of program A (16:00). In the second b, the event ID of the program B, the start time of the program B (16:00), the end time of the program B (17:00), the start time of the program B (16:00), And the end time of program B (17:00). In addition, b, which is three-packed, includes the event ID of the program C and the start time of the program C (17:
00), the end time of program C (18:00), the start time of program C (17:00), and the reservation end time (17:30) input by the user. Therefore, the start time of the program A based on the SI data is 15:00, but the reservation start time input by the user is 1:30. Things. Similarly, the end time of program C is 18:00
However, the reservation end time is 17: 3 set by the user.
Set to 0.

Next, the reservation execution section 19 compares the current time with the earliest start time of the program-specific reservation data structures stored in the program-specific reservation data storage section 18. At the same time, with respect to the program-specific reservation data structure stored in the program-specific reservation data storage unit 18, the reservation data creating unit 17 updates the SI program data structure corresponding to the program of the program-specific reservation data structure. Then, whether or not the data is stored in the SI program data storage unit 12 is checked by a handler that is activated several times a day. Then, on the transmitting side, the content of the SI data including the program information of the program described in the program-specific reservation data structure stored in the program-specific reservation data storage unit 18 is updated, and the updated SI data is transmitted to the digital radio wave. From the signal received by the tuner unit 21 and demodulated by the QPSK unit 22,
In step 3, the updated SI data is separated and the SI management unit 11
Output to

Next, the SI management unit 11
The I data is analyzed, an updated SI program data structure is created from the updated SI data, and the updated SI program data structure is stored in the SI program data storage unit 12 in place of the stored pre-updated SI program data structure. I do. Next, the reservation data creation unit 1
7 shows the same service ID, event ID, and event ID as those of the program-specific reservation data structures stored in the program-specific reservation data storage unit 18 for which the reservation time tracking is selected among the program-specific reservation data structures. And, the one containing the date MJD is searched from the SI program data structure stored in the SI program data storage unit 12. If the start time and the end time of the two structures are different from each other within a certain range of time (for example, 15 minutes to 10 hours), the start time and the end time of the program-specific reservation data structure are updated, and the program-specific reservation data storage unit is updated. Save to 18. If the program-specific reservation data structure follows the reservation time, the reservation start time and the reservation end time are also updated, and the same times as the updated start time and end time are entered.

For example, in the time setting shown in FIG. 3, if the user has selected the reservation time tracking, the first start time and the end time in FIG. The start time (15:45) and end time (16:45) of the program A described in the specified program information are updated, and the reservation start time and the reservation end time are also 15: 4.
5 and updated at 16:45. Similarly, the second and three
The start time, end time, reservation start time, and reservation end time of the second b are also 16:45, 17:45, 1
6:45, 17:45, 17:45, 18: 4
5, 17:45 and 18:45.

On the other hand, as for the program-specific reservation data structure for which the reservation time tracking is not selected, the service ID and the service ID of the program-specific reservation data structure are obtained from the SI program data structure stored in the SI program data storage unit 12. The same thing as the input reservation date enters the service ID and the date MJD, and any time from the input reservation start time to the input reservation end time of the program-specific reservation data structure is the start time or the end time. Search for what goes in. SI searched
The program-specific reservation data structure is updated based on the program data structure.

For example, in the time setting shown in FIG. 3, if the user does not select the reservation time tracking, the first event ID, the start time, and the end time in FIG. The time includes the event ID of the program D, the input reservation start time of the program-specific reservation data structure (15:30), and the end time of the program D (15:45).
Enters. In addition, the event ID of the second b, the start time,
The event ID of the program A, the start time of the program A (15:45), and the end time of the program A (16:45) are entered in the end time and the end time, respectively. Further, the event ID, start time, and end time of the third b are the start time of program B (16:45) and the end time of input reservation (17:30) of the program-specific reservation data structure, respectively. Enters. Therefore, the time to actually start the reservation for the first program and the time to actually end the reservation for the last program are:
The reservation start time and the reservation end time set by the user remain the same.

Next, when the start time of the program-specific reservation data structure stored in the program-specific reservation data storage unit 18 coincides with the current time, the reservation execution unit 19 selects the channel selection unit 20. Service ID and Event I
D is output. If a recording reservation is made, a recording deck operation signal is transmitted to the recording device at the same time. Next, the tuner 20 multiplexes the program having the service ID and the event ID from the digital signal superimposed on the digital radio wave, transmitted by the tuner 21 Separates digital video signals.

Next, the AV decoder section 24 decodes the digital video signal from the demultiplexing section 23 and outputs it as an analog video signal. Next, the NTSC encoder section 25 decodes the analog video signal decoded by the AV decoder section 24. The video signal is encoded into an NTSC standard video signal and output. Therefore, if the user has selected to follow the reserved time, when a program scheduled to be broadcast in the reserved time zone is broadcast with a changed time, the programmed time zone is followed by the changed broadcast time zone. Are updated, and the program reserved in the updated time zone is displayed, and if the reservation time tracking is not selected, the program broadcast in the reserved time zone is displayed.

As described above, in the broadcast receiving apparatus according to the first embodiment of the present invention, before the program information to be referred arrives, the reservation setting means sets the reservation according to the reservation time zone specified by the external input. When the program information arrives, the reservation data creation means specifies a program to be broadcast in the reservation time zone set from the program information, and sets program-specific reservation data describing a reservation start time and a reservation end time for each program. The reservation execution means creates and executes the reservation by instructing the selection of the reserved program when the reservation start time arrives according to the program-specific reservation data, so that the user does not have the program information of the program to be reserved. At the time of arrival, a reservation can be made by specifying a time zone. Further, since the reservation time zone is specified by the reservation date, the reservation start time, and the reservation end time, the user can specify the time zone.

In addition, when the reserved program changes the broadcast time zone, the reservation setting means determines whether to update the time zone of the program-specific reservation data in accordance with the changed broadcast time zone. However, the reservation data is set by adding the time tracking information indicating whether the time tracking information has been selected by an external input. If the time tracking information has selected the tracking, the updated program information has arrived. At this time, the broadcast start time and the broadcast end time of the changed program are obtained from the program information, and the reservation start time and the broadcast end time of the program-specific reservation data of the program are obtained, respectively. Even if the broadcast time zone of the program scheduled to be broadcast changes in the reserved time zone, the user does not need to reset the reserved time zone,
It is possible to view or record a desired program.

(Embodiment 2) FIG. 4 is a diagram showing a data structure used in a broadcast receiving apparatus according to Embodiment 2 of the present invention. The data structure is almost the same as the data structure of FIG. 2 described above, and therefore, different members will be mainly described. As shown, the SI program data structure is:
This is exactly the same as that of FIG. Further, in the input reservation data structure, the reservation date in FIG. 2 is “reservation date” or “every day reservation” or “every ○ day reservation”. As in the first embodiment, the user selects a program for which reservation is desired,
Instead of making a reservation by designating a channel on which the program is broadcast, a reservation date, a reservation start time, and a reservation end time, instead of specifying the program name or event ID, the program is also broadcasted daily or weekly on the same channel and time zone. If the user wants to make a reservation on a day of the week, the user inputs a reservation every day or every week on a day instead of the reservation date. Further, in the program-specific reservation data structure, daily / weekly reservation information is added to the member, and the member indicates whether the reservation setting is daily reservation or weekly 曜 日 day reservation. Therefore,
If the daily / weekly reservation information contains information of either daily reservation or weekly day reservation, the input reservation date and the date MJD of the program-specific reservation data structure include the first reservation. The date corresponding to the day enters.

Next, a description will be given, with reference to FIGS. 1 and 4, of a time tracking operation by daily / weekly reservation in the broadcast receiving apparatus according to the second embodiment of the present invention. First, when the user inputs a service ID (channel) to be reserved, a daily reservation or a weekly reservation, a start time, and an end time by a key operation on a remote controller or the like, the input analysis unit 1
3 acquires reservation data by interpreting the input key,
The reservation data is output in the form of an input reservation data structure.

Next, the EPG control unit 14 outputs the information of the input reservation data structure from the input analysis unit 13 to the OSD display unit 26, and the OSD display unit 26 displays the reservation time together with the contents of the input reservation data structure. A screen is displayed that displays a message that allows the user to select whether or not to follow.

Next, the OSD display unit 26 creates a display screen according to the instruction of the EPG control unit 14 and outputs the display screen to the NTSC encoder unit 25. Next, the NTSC encoder unit 25 encodes the display screen data created by the OSD display unit 26 and outputs it as an NTSC standard video signal, and the created screen is displayed. Here, the user confirms the reservation contents (service ID, reservation every day or reservation every week, reservation start time, reservation end time) from the screen, and selects whether or not the user wants to follow the reservation time using a remote controller or the like. I do. Next, the input analysis unit 13 interprets the key input to the remote controller or the like, determines whether or not the reservation time tracking is selected, and outputs the determination result. Then
The EPG control unit 14 outputs the input reservation data structure to the reservation setting unit 15 together with the determination result (whether or not to follow the reservation time). Next, the reservation setting unit 15 stores the input data structure and the determination result from the EPG control unit 14 in the input reservation data storage unit 16.

Next, the reservation data creation unit 17 is a handler that is activated several times a day,
It is checked whether an SI program data structure corresponding to the input reservation data structure stored in the input reservation data storage unit 16 is stored. That is, the storage of the SI program data structure corresponding to the first reservation date is checked from the daily reservation of the input reservation data structure or the reservation every weekday. By the way, if the daily reservation is selected, the corresponding SI program data structure should already be stored. Next, when the reservation data creation unit 17 confirms that the SI program data structure corresponding to the input reservation data structure stored in the input reservation data storage unit 16 is stored in the SI program data storage unit 12, A program-specific reservation data structure is created from the input reservation data structure and the SI program data structures of all the programs in the reservation time zone of the first reservation date, and the program-specific reservation data storage unit 18 is prepared.
To save. The example of creating the program-specific reservation data structure is exactly the same as that described with reference to FIG. 3 in the first embodiment, and the time shown in FIG. 3 is set by the user in the first embodiment. The second embodiment differs from the first embodiment in that the time on the specific date is the time on the first reservation date as a result of the user selecting daily reservation or weekly 曜 day reservation. It is.

Next, the reservation executing section 19 compares the current time with the earliest start time of the program-specific reservation data structures stored in the program-specific reservation data storage section 18 (S1). . At the same time, the reservation data creation unit 17
Regarding the program-specific reservation data structure stored in the program-specific reservation data storage unit 18, the SI program data structure corresponding to the program of the program-specific reservation data structure is updated,
Whether or not the data is stored in the SI program data storage unit 12 is checked by a handler which is activated several times a day (S2). Then, on the transmission side, the content of the SI data including the program information of the program described in the program-specific reservation data structure stored in the program-specific reservation data storage unit 18 is updated, and the updated S
The I data is superimposed on the digital radio wave and transmitted. The multiplexing / demultiplexing unit 23 separates the updated SI data from the signal received by the tuner unit 21 and demodulated by the QPSK unit 22 and output to the SI management unit 11. (S3).

Next, the SI management unit 11
The I data is analyzed, an updated SI program data structure is created from the updated SI data, and stored in the SI program data storage unit 12 in place of the stored pre-updated SI program data structure. (S4). Next, the reservation data creating unit 17 determines, for the program-specific reservation data structures stored in the program-specific reservation data storage unit 18, the same as the program-specific reservation data structure for those for which the reservation of the reservation time is selected. Service ID, event ID, and date M
The one containing the JD is searched from the SI program data structure stored in the SI program data storage unit 12. If the start time and the end time of the two structures are different from each other within a certain range, the start time and the end time of the program-specific reservation data structure are updated and stored in the program-specific reservation data storage unit 18. If the program-specific reservation data structure follows the reservation time, the reservation start time and the reservation end time are also updated, and the same times as the updated start time and end time are entered.

On the other hand, for the program-specific reservation data structure for which the reservation time tracking is not selected, the service ID and the service ID of the program-specific reservation data structure are stored in the SI program data structure stored in the SI program data storage unit 12. The same thing as the input reservation date enters the service ID and the date MJD, and any time from the input reservation start time to the input reservation end time of the program-specific reservation data structure is the start time or the end time. Search for what goes in. SI searched
The program-specific reservation data structure is updated based on the program data structure (S5).

Next, the reservation executing section 19, when the current time coincides with the earliest start time of the program-specific reservation data structures stored in the program-specific reservation data storage section 18, is used. Service ID and Event I
D is output. If a recording reservation is made, a recording deck operation signal is simultaneously sent to the recording device (S6). Next, the tuner 20 multiplexes the program having the service ID and the event ID from the digital signal transmitted by being superimposed on the digital radio wave, received by the tuner 21 and demodulated by the QPSK 22, by the demultiplexer 23. The digital video signal is separated (S7). Next, the AV decoder unit 24 decodes the digital video signal from the demultiplexing unit 23 and outputs it as an analog video signal (S
8).

Next, the NTSC encoder unit 25
The analog video signal decoded by the V decoder
Encodes and outputs an SC standard video signal (S
9). Next, the reservation execution unit 19 executes the reservation for the program-specific reservation data structure stored in the program-specific reservation data storage unit 18 and which includes information of daily / weekly reservation, and ends the processing. At this time, the fact is output to the reservation data creation unit 17 (S21). Next, the reservation data creation unit 17 receives the output from the reservation execution unit 19, and inputs the reservation date / month and year of the program-specific reservation data structure in the program-specific reservation data storage unit 18 that has been reserved and executed. The date MJD is updated on the next reservation date, and the handler is activated. In the handler, the SI program data storage unit 12
Then, it is checked whether or not the SI program data structure corresponding to the updated program-specific reservation data structure is stored (S22).

Next, when the reservation data creating unit 17 confirms that the SI program data structure corresponding to the updated program-specific reservation data structure is stored in the SI program data storage unit 12, the updated SI program data structure is updated. A program-specific reservation data structure is created from the program-specific reservation data structure and the SI program data structures of all programs in the updated reservation time zone of the reservation date, and the program-specific reservation data storage unit 18 is prepared. (S23). Next, the same operation as S1 to S9 is performed to display a program scheduled to be broadcast on the next day or the next week on the same channel and time zone. Thereafter, the operations of S21 to S23 and S1 to S9 are repeated to display a program scheduled to be broadcast on the same channel and the same time zone for many days or weeks.

As described above, in the broadcast receiving apparatus according to the second embodiment of the present invention, before the program information to be referred arrives, the reservation setting means sets the reservation according to the reservation time zone specified by the external input. When the program information arrives, the reservation data creation means specifies a program to be broadcast in the reservation time zone set from the program information, and sets program-specific reservation data describing a reservation start time and a reservation end time for each program. The reservation executing means creates and executes the reservation by instructing the channel selection of the reserved program when the reservation start time arrives according to the program-specific reservation data. At the time of arrival, a reservation can be made by specifying a time zone.

The reservation time zone is designated by a daily reservation mode or a weekly reservation mode, a reservation start time and a reservation end time, and the reservation data creation means selects the shortest time from the current time among the designated reservation time zones. For each program scheduled to be broadcast in the reserved time slot, program-specific reservation data is created, and when the program execution of the program of the program-specific reservation data is executed by the reservation executing means, the program-specific reservation data is discarded. Accordingly, the user can specify the same time zone on the same day of the week or every week at a time, and can execute the program for days or weeks without resetting the program.

In addition, when the reserved program changes the broadcast time zone, the reservation setting means determines whether or not to update the time zone of the program-specific reservation data in accordance with the changed broadcast time zone. However, the reservation data is set by adding the time tracking information indicating whether the time tracking information has been selected by an external input. If the time tracking information has selected the tracking, the updated program information has arrived. At this time, the broadcast start time and the broadcast end time of the changed program are obtained from the program information, and the reservation start time and the broadcast end time of the program-specific reservation data of the program are obtained, respectively. Even if the broadcast time zone of the program scheduled to be broadcast changes in the reserved time zone, the user does not need to reset the reserved time zone,
It is possible to view or record a desired program.

(Embodiment 3) FIG. 5 is a diagram showing a data structure used in a broadcast receiving apparatus according to Embodiment 3 of the present invention. Since the data structure is almost the same as the data structure of FIGS. 2 and 4, different members will be mainly described. As shown, the SI program data structure is exactly the same as that of FIGS. 2 and 4 above. In addition, the input reservation data structure includes correction information added to the member, and the member indicates which of the correction methods preset by the user has been selected. Further, in the program-specific reservation data structure, correction information is added corresponding to the input reservation data structure. The reservation start time and the reservation end time indicated by b are compared with the start time and the end time extracted from the program information and the input reservation start time and the input reservation end time, as in the first and second embodiments. Are members calculated as the time at which the reservation is actually started and the time at which the reservation is actually ended. In the third embodiment, the members are calculated by different calculation methods according to the method of correcting the reservation time. Several methods of correcting the reserved time are set in the broadcast receiving apparatus in advance, and the user selects one of them.

FIG. 6 is a diagram showing a method of correcting the reserved time selected by the user in the third embodiment of the present invention. As in the first embodiment, the user wants to reserve a program that is broadcast every week in the same time zone on the same channel for the broadcast several weeks ahead. When arriving, the program guide several weeks ahead cannot be displayed, so make a reservation by specifying the channel and time zone. At the same time, one of four preset reservation time correction methods A to D is selected.

In FIG. 6, "no correction" of A means that the reservation start time (18:00) and the input reservation end time (19:00) input by the user are unchanged without any change. 18: 00: 00) and the reservation end time (19: 00: 00) are set, and "correct the input reservation start time several seconds before" of B is the reservation start time of A (18:00). :) Is set several seconds before the input reservation start time input by the user (for example, 17:59:55 in the case of five seconds before).

The "correction of the program break time and the input reservation start / end time within a few minutes to the break time" in C means that the programs A to be broadcasted in the time zone input by the user. C break time (17:55, 18:25,
18:55 and 19:25) and within minutes (for example, 5
Input reservation start time (18:00)
And the input reservation end time (19:00) as the break time (17:55:00 and 18:55:00, respectively).
0) and set the reservation start time (17:55:00) and the reservation end time (18:55:00). In this case, program C is not reserved, but if the break time between program B and program C is 19:10 instead of 18:55, the input reservation end time (19:00) and the program within 5 minutes Since there is no break time, the input reservation end time (19: 0
0), the reservation end time (19:00:00) is set.

Further, "correction of input reservation start time several seconds before in addition to correction of C" of D means that only the corrected reservation start time (17:55:00) after correction in the same manner as C , And a few seconds before (for example, 5 seconds before, 1
7:59:55).

Next, the operation of correcting the reserved time in the broadcast receiving apparatus according to the third embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to 2, 5, and 6. First, when a user inputs a channel and a time zone to be reserved to a remote controller or the like by key operation, the input analysis unit 13 interprets the input key to obtain reservation data, and stores the reservation data in an input reservation data structure. Output in the form of a body. Then, EP
The G control unit 14 outputs information on the input reservation data structure from the input analysis unit 13 to the OSD display unit 26, and displays the information on the OSD display unit 26 together with the contents of the input reservation data structure in FIG.
And a screen displaying a message for prompting the user to select one of them.

Next, the OSD display unit 26 creates a display screen according to the instruction of the EPG control unit 14 and outputs the display screen to the NTSC encoder unit 25. Next, the NTSC encoder unit 25 encodes the display screen data created by the OSD display unit 26 and outputs it as an NTSC standard video signal, and the created screen is displayed. Here, the user confirms the reservation contents (service ID, reservation date, reservation start time, reservation end time) from the screen, and selects a reservation time correction method using a remote controller or the like.

Next, the input analyzer 13 interprets the key input to the remote controller or the like, determines which correction method has been selected, and outputs the result of the determination. Then, EP
The G control unit 14 outputs the result of the determination (the method of correcting the reservation time) to the reservation setting unit 15 in addition to the input reservation data structure. Next, the reservation setting unit 15 stores the input data structure from the EPG control unit 14 in the input reservation data storage unit 16. Next, the reservation data creation unit 17 is, for example, a handler that is activated once a day, and
Next, it is checked whether or not the SI program data structure corresponding to the input reservation data structure stored in the input reservation data storage unit 16 has been stored. Then, the SI data including the program information of the reserved time zone is transmitted by being superimposed on the digital radio wave, received by the tuner section 21 and transmitted to the QPSK section 2.
The multiplexing / demultiplexing unit 23 separates the SI data from the signal demodulated in step 2 and outputs it to the SI management unit 11.

Next, the SI management unit 11
The EIT data of the I data is analyzed, an SI program data structure is created from the EIT data, and stored in the SI program data storage unit 12. Next, the reservation data creation unit 17
In the I program data storage unit 12, an input reservation data storage unit 16
Corresponding to the input reservation data structure stored in the
When it is confirmed that the program data structure has been stored, the input reservation data structure and the SI program data structures of all the programs relating to the reservation time bodies included in the input reservation data structure are identified by the program By configuring the members of the reservation data structure and further correcting the reservation start time and the reservation end time of the configured members based on the correction information of the input reservation data structure, the program-specific reservation data structure is changed. It is created and stored in the program-specific reservation data storage unit 18. That is, the program-specific reservation data structure is used by the user to select the reservation start time of the first program and the reservation end time of the last program among members created in exactly the same manner as in the first and second embodiments. It is created by performing the correction as shown in FIG. 6 according to the correction method described above.

Next, the reservation execution section 19 compares the current time with the earliest start time of the program-specific reservation data structures stored in the program-specific reservation data storage section 18. When they match, the service ID and the event ID are output to the tuning unit 20. If a recording reservation is made, a recording deck operation signal is transmitted to the recording device at the same time. Next, the tuner 20 converts the digital signal superimposed on the digital radio wave, transmitted and received by the tuner 21 and demodulated by the QPSK 22 into a demultiplexer 2.
In step 3, the digital video signal of the program having the service ID and the event ID is separated. Next, the AV decoder unit 24 decodes the digital video signal from the demultiplexing unit 23 and outputs it as an analog video signal. Next, the NTSC encoder unit 25 outputs the AV decoder unit 2
The analog video signal decoded in step 4 is encoded into an NTSC standard video signal and output. Therefore, the start time and the end time set by the user are corrected according to the correction method of the reservation time selected by the user, and the program is displayed from the set reservation start time to the reservation end time.

As described above, in the broadcast receiving apparatus according to the third embodiment of the present invention, before the program information to be referred arrives, the reservation setting means sets the reservation according to the reservation time zone specified by the external input and the correction method. When the program information arrives, the reservation data creation means obtains, from the program information, the reservation start time and the reservation end time of the program scheduled to be broadcast in the set reservation time zone. By correcting the acquired broadcast start time or the set reservation start time, and the acquired broadcast end time or the set reservation end time, the program-specific reservation data is created as the program reservation start time and the reservation end time, respectively. The reservation executing means executes the reservation by instructing the channel selection of the reserved program when the reservation start time arrives according to the program-specific reservation data, Even when the program information of the program to be reserved has not arrived, the user can not only make a reservation by specifying a time zone, but also select a correction method, and the user does not need to adjust the time, According to the selected correction method, it is possible to execute the reservation at an appropriate time at which the specified reservation start time or reservation end time is adjusted.

The above-mentioned correction method includes a first method of not correcting, a second method of correcting the set reservation start time several seconds to several minutes before, and a broadcast start time or broadcast obtained from the set reservation start time. End time (program break time)
Is within a fixed time, the set reservation start time is corrected to the break time of the program within the fixed time, and when the break time of the program is within the fixed time from the set reservation end time, the setting is made. A third method of correcting the reserved end time that has been set to a break time of a program within a certain time, and a fourth method of correcting the reserved start time from several seconds to several minutes before after correcting the third method. , The user can select a desired correction method from various correction methods,
The first method can be selected to execute the reservation as set, the second method can be selected, the fully displayed program can be viewed from the broadcast start time, and the third method can be selected. do it,
For a program whose broadcast starts or ends with a difference of, for example, only about 5 minutes from the reservation start time or the reservation end time set by the user, it is possible to view the entire program or to view only a part of the program. It is possible to avoid the reservation of the second method by selecting the fourth method.
And the effects of the third method can be obtained together.

As in the first and second embodiments,
If the time following can be selected and the correction method of FIG. 6B is selected, the operation is performed in the same manner as in the first and second embodiments, and the program scheduled to be broadcast in the reserved time zone is changed to the time zone. Is updated and broadcasted, the updated broadcast time zone can be followed, and the reservation start time can be changed and set several seconds before the broadcast start time.

(Embodiment 4) FIG. 7 is a diagram showing a data structure used in a broadcast receiving apparatus according to Embodiment 4 of the present invention. The data structure is almost the same as the data structure of FIG. 2 described above, and therefore, different members will be mainly described. As shown in the figure, in the SI program data structure, PPV information is added to a member, and the member indicates whether the program of the SI program data structure is a PPV program. Further, in the input reservation data structure, PPV reservation information is added to the member, and the member indicates whether the user has designated PPV purchase or PPV non-purchase.
That is, as in the first embodiment, the user
Programs that are broadcast on the same channel at the same time,
It is also desirable to make a reservation for broadcasts several weeks ahead. However, if program information several weeks ahead has not arrived, a program guide several weeks ahead cannot be displayed. At this time, since the program information has not arrived, it is unknown whether the program broadcast in the designated time zone is a PPV program,
You cannot purchase a PPV program unless you indicate the intention to purchase it. Therefore, if the reservation is made by specifying only the channel and the time zone and the reservation intention arrives at a later date without confirming whether or not the program is a PPV program, the purchase cannot be determined as unknown. . In order to avoid this situation, whether or not to purchase a PPV program is selected together with the channel and time zone. Further, in the program-specific reservation data structure, P
The PV purchase information is added to the member, and the member determines that the program having the event ID of the program-specific reservation data structure is a PP.
It indicates whether or not the user has designated purchase, along with whether or not the program is a V program.

FIG. 8 is a diagram showing a PPV purchase designation method selected by the user when program information has not arrived in the fourth embodiment of the present invention. As shown in FIG. 8, the PPV purchase designation method includes “all programs”, which selects whether or not to purchase all programs broadcasted during the reserved time zone set by the user, and “all programs”. There are two types of “only fully reserved programs” in which only the program whose broadcasting time period is completely included in the reserved time period is purchased, and the program whose broadcasting time period extends beyond the reserved time period is not purchased. In addition, if the user
When the V purchase designation method is selected, the scheduled broadcast time shown in the figure is not fixed because the program information has not arrived, and the scheduled broadcast time is determined when the program information arrives. Accordingly, since it is not known that the program D is not a PPV program, the program is purchased. Incidentally, a program that is not a PPV program is set to be reserved regardless of whether PPV purchase or PPV non-purchase is selected.

Next, the operation of reservation purchase of a PPV program in the broadcast receiving apparatus according to the fourth embodiment of the present invention will be described.
This will be described with reference to FIGS. First, when a user inputs a channel and a time zone to be reserved to a remote controller or the like by key operation, the input analysis unit 13 interprets the input key to obtain reservation data, and stores the reservation data in an input reservation data structure. Output in the form of a body. Then E
The PG control unit 14 outputs the information of the input reservation data structure from the input analysis unit 13 to the OSD display unit 26,
The display unit 26 displays the contents of the input reservation data structure and the two types of PPV purchase designation methods shown in FIG.

Next, the OSD display unit 26 creates a display screen in accordance with the instruction from the EPG control unit 14 and outputs it to the NTSC encoder unit 25. Next, the NTSC encoder unit 25 encodes the display screen data created by the OSD display unit 26 and outputs it as an NTSC standard video signal, and the created screen is displayed. Here, the user confirms the reservation contents (service ID, reservation date, reservation start time, reservation end time) from the screen, and selects a PPV purchase designation method using a remote controller or the like.

Next, input analysis section 13 interprets the key input to the remote controller or the like, determines which PPV purchase designation method has been selected, and outputs the determination result. Next, the EPG control unit 14 adds the determination result (PPV purchase designation method) to the input reservation data structure as PPV reservation information, and outputs the result to the reservation setting unit 15. Next, the reservation setting unit 15 stores the input data structure from the EPG control unit 14 in the input reservation data storage unit 16. Next, the reservation data creation unit 17 uses a handler that is activated several times a day,
It is checked whether or not the program data storage unit 12 stores an SI program data structure corresponding to the input reservation data structure stored in the input reservation data storage unit 16. Then, the SI data including the program information of the reserved time zone is superimposed on the digital radio wave and transmitted. It is separated and output to the SI management unit 11.

Next, the SI management unit 11
The EIT data of the I data is analyzed, an SI program data structure is created from the EIT data, and stored in the SI program data storage unit 12. Next, the reservation data creation unit 17
In the I program data storage unit 12, an input reservation data storage unit 16
Corresponding to the input reservation data structure stored in the
When it is confirmed that the program data structure has been stored, the program-specific data is obtained from the input reservation data structure and the SI program data structures of all the programs related to the reservation time bodies contained in the input reservation data structure. A reservation data structure is created and stored in the program-specific reservation data storage unit 18.

For example, when the user selects “only the completely reserved program” as the PPV purchase designation method in the time setting shown in FIG. 8, the input reservation start shown in FIG. The time and the input reservation end time are the reservation start time (18: 0) set by the user, respectively.
0) and the reservation end time (19:00), and the event ID, start time, end time, reservation start time, reservation end time, and PPV purchase information shown in b include, for each of the programs A to E, The event ID and time of each program are entered. That is, the first b includes the event I of the program A
D, the start time of program A (17:55), the end time of program A (18:10), and the reservation start time (1
8:00), the end time of program A (18:10), and PPV purchase information (2) of program A (see the outside of FIG. 7).
In the second b, the event ID of the program B, the start time of the program B (18:10), and the end time of the program B (1
8:25), start time of program B (18:10), program B
(18:25) and the PPV purchase information (1) of the program B are entered. Similarly, information about programs C and D is entered in the third and fourth b, respectively. However, since program D is not a PPV program, the fourth b P
The PV purchase information is (0). In the fifth b,
The event ID of the program E and the start time of the program E (1
8:55), end time of program E (19:10), program E
(18:55), reservation end time (19:00) set by the user, and PPV purchase information (2) for program E.

Next, the reservation execution section 19 compares the current time with the earliest start time of the program-specific reservation data structures stored in the program-specific reservation data storage section 18. When they match, the service ID and the event ID are output to the tuning unit 20. If a recording reservation is made, a recording deck operation signal is transmitted to the recording device at the same time. Next, the tuner 20 converts the digital signal superimposed on the digital radio wave, transmitted and received by the tuner 21 and demodulated by the QPSK 22 into a demultiplexer 2.
In step 3, the digital video signal of the program having the service ID and the event ID is separated. Next, the AV decoder unit 24 decodes the digital video signal from the demultiplexing unit 23 and outputs it as an analog video signal. Next, the NTSC encoder unit 25 outputs the AV decoder unit 2
The analog video signal decoded in step 4 is encoded into an NTSC standard video signal and output. Therefore, the PPV purchase designation method selected by the user is "only for fully reserved programs".
In the case of, only programs that are completely broadcast in the time zone set by the user are displayed, and in the case of "all programs", all programs broadcast in the time zone set by the user are displayed. In addition,
In either case, the reservation is not started earlier than the start time set by the user, or the reservation is not ended later than the end time set by the user.

As described above, in the broadcast receiving apparatus according to the fourth embodiment of the present invention, before the program information to be referred arrives, the reservation setting means sets the reserved time zone specified by the external input and the PPV purchasing method. When the program information arrives, the reservation data creation means uses the program information to determine the reservation start time and reservation end time of a program scheduled to be broadcast in the set reservation time zone, and whether the program is a PPV program. , And from the obtained information, if the program is a PPV program, a designated PPV purchase method and program-specific reservation data are created, and the reservation execution means arrives at a reservation start time according to the program-specific reservation data. At this time, the reservation is executed by instructing the channel selection of the reserved program. For the program selected as the PPV program not to be purchased, the channel selection of the reserved program is performed even if the reservation start time comes. Since the instruction is not executed and the reservation is not executed, when the program information of the program to be reserved has not arrived, the user can not only specify a time zone and make a reservation but also select a PPV purchasing method. Accordingly, even if the program scheduled to be broadcast in the set reservation time zone is a PPV program, the user can execute the reservation to purchase the PPV program or cancel the reservation and do not purchase the PPV program according to the selected PPV purchasing method. It can be.

The above-mentioned PPV purchasing method includes a method of purchasing all programs scheduled to be broadcast during a reserved time slot, and a method of purchasing only a program having a broadcast start time and a broadcast end time during a reserved time slot. Thus, it is possible to avoid purchasing a PPV program that cannot be viewed as a whole because the reservation is started in the middle of the program or the reservation is canceled in the middle of the program.

(Embodiment 5) FIG. 9 is a diagram showing a data structure used in a broadcast receiving apparatus according to Embodiment 5 of the present invention. The data structure is almost the same as the data structure of FIG. 2 described above, and therefore, different members will be mainly described. As shown in the figure, in the SI program data structure, copy guard information is added to a member, and the member indicates whether the program of the SI program data structure is a copy guard program.

In the input reservation data structure, copy guard notification information is added to the member, and the member indicates which of the preset copy guard warning methods the user has selected. In other words, in the fifth embodiment of the present invention, similarly to the first embodiment, the user reserves a program broadcast every week in the same time zone on the same channel for a broadcast several weeks ahead. If the program information of a few weeks ahead has not arrived, a program guide of a few weeks ahead cannot be displayed, so a reservation is made by specifying a channel and a time zone. At this time, since the program information has not arrived, it is unknown whether the program broadcasted in the designated time zone is a copy guard program. No record will be made. To avoid this situation, after the user sets a reservation, when program information arrives and it is determined that the program is a copy guard program, a warning is issued to the user to avoid useless recording reservation. In this case, as a copy guard warning method, after it is determined that the program is a copy guard program,
When the user displays the screen, a warning message is displayed on the screen ("display a warning message"). When the user displays the program table, a warning is displayed on the program table ("warning display on the program table"). )). At the time of reservation setting, the user is made to select one of these warning methods and three types of “warning unnecessary” in which no warning is given.
Further, in the program-specific reservation data structure, copy guard warning information is added to the member, and the member determines whether the program having the event ID of the program-specific reservation data structure is a copy guard program, and whether the program is a copy guard program. For example, it indicates whether the user has been warned.

Next, the operation of recording a copy guard program in the broadcast receiving apparatus according to the fifth embodiment of the present invention will be described with reference to FIGS. First, when a user inputs a channel and a time zone to be reserved to a remote controller or the like by key operation, the input analysis unit 13 interprets the input key to obtain reservation data, and stores the reservation data in an input reservation data structure. Output in the form of a body. Then
The EPG control unit 14 outputs the information of the input reservation data structure from the input analysis unit 13 to the OSD display unit 26,
D display unit 26, along with the contents of the input reservation data structure,
The above-described three types of copy guard warning methods are shown, and a screen displaying a message for allowing the user to select one is created.

Next, the OSD display unit 26 creates a display screen according to the instruction of the EPG control unit 14 and outputs the display screen to the NTSC encoder unit 25. Next, the NTSC encoder unit 25 encodes the display screen data created by the OSD display unit 26 and outputs it as an NTSC standard video signal, and the created screen is displayed. Here, the user confirms the reservation contents (service ID, reservation date, reservation start time, reservation end time) from the screen, and selects a warning method for the copy guard program using a remote controller or the like. Next, the input analysis unit 13 interprets the key input to the remote controller or the like, determines which copy guard warning method has been selected, and outputs the determination result. Next, the EPG control unit 14 adds the determination result (copy guard warning method) to the input reservation data structure and outputs the result to the reservation setting unit 15. Next, the reservation setting unit 15 stores the input data structure from the EPG control unit 14 in the input reservation data storage unit 16. Next, the reservation data creation unit 17 is a handler that is activated several times a day. The SI program data storage unit 12 stores an SI program data structure corresponding to the input reservation data structure stored in the input reservation data storage unit 16 in the handler. Check if it has been stored. Then, the SI data including the program information of the reserved time zone is superimposed on the digital radio wave and transmitted. It is separated and output to the SI management unit 11.

Next, the SI management unit 11
The EIT data of the I data is analyzed, an SI program data structure is created from the EIT data, and stored in the SI program data storage unit 12. Next, the reservation data creation unit 17
In the I program data storage unit 12, an input reservation data storage unit 16
Corresponding to the input reservation data structure stored in the
After confirming that the program data structure has been stored, a program-specific reservation data structure is created from the input reservation data structure and the SI program data structures of all programs related to the reservation time zone, It is stored in the program-specific reservation data storage unit 18.

For example, when the user selects “display warning message” or “display warning on program guide” as the copy guard warning method in the time setting shown in FIG. 10,
In the program-specific reservation data structure, the input reservation start time and the input reservation end time shown in FIG. 9A include the reservation start time (18:00) and the reservation end time (19:00) set by the user, respectively. In the event ID, start time, end time, reservation start time, reservation end time, and copy guard warning information shown in b, the event ID and time of each program are entered for each of the programs A to E. That is, 1
In the second b, the event ID of the program A and the program A
Start time (17:55), end time of program A (18:55)
10), the reservation start time set by the user (18: 0)
0), the end time of program A (18:10), and copy guard warning information (2) of program A (see FIG. 9). Similarly, information about programs B to E is entered in the second to fifth b, respectively. However, since the programs B, C and E are not copy guard programs, the copy guard warning information of the second, third and fifth b is (0). Also, 5
The input reservation end time (19:10) set by the user is entered as the second reservation end time.

Next, the EPG control unit 14 sets the copy guard warning information in the program-specific reservation data structure stored in the program-specific reservation data
At the same time, an input reservation data structure (including a copy guard warning method) corresponding to the program-specific reservation data structure stored in the input reservation data storage unit 16 is retrieved. If the copy guard warning method is “display a warning message”, when the user turns on the power via the input analysis unit 13 and displays the screen, the information of the program-specific reservation data structure is displayed on the OSD display unit 26. Then, the OSD display unit 26 makes the OSD display unit 26 create a warning message screen indicating, for example, that there is a program that cannot be recorded among reserved programs. If the result of the determination is “warning display on program table”, when the user displays the program table via input analysis unit 13, the SI program data structure stored in SI program data storage unit 12 is displayed. And causes the OSD display unit 26 to create a screen for displaying a warning of a copy guard program on the program table based on the SI program data structure and the program-specific reservation data structure. If the judgment result is "warning unnecessary", the copy guard warning information of the extracted program-specific reservation data structure is re-entered with 1 and the program-specific reservation data structure is stored in the program-specific reservation data storage unit 18. I do.

Next, the OSD display unit 26 creates a display screen for warning according to the instruction of the EPG control unit 14 and outputs it to the NTSC encoder unit 25. Then N
The TSC encoder unit 25 encodes the display screen data created by the OSD display unit 26 and outputs it as an NTSC standard video signal, and the created alert screen is displayed. Next, the EPG control unit 14 adds 1 to the copy guard warning information of the extracted program-specific reservation data structure, and stores the program-specific reservation data structure in the program-specific reservation data storage unit 18.

Next, the reservation executing unit 19 compares the current time with the earliest start time of the program-specific reservation data structures stored in the program-specific reservation data storage unit 18. When they match, the service ID and the event ID are output to the tuning unit 20, and a recording deck operation signal is transmitted to the recording device.

Next, the tuning section 20 is superimposed on the digital radio wave and transmitted, received by the tuner section 21 and transmitted to the QPS.
The digital signal demodulated by the K unit 22 is separated by the demultiplexing unit 23 into a digital video signal of a program having the service ID and the event ID. Then, AV
The decoder 24 decodes the digital video signal from the demultiplexer 23 and outputs it as an analog video signal. Next, the NTSC encoder unit 25 encodes the analog video signal decoded by the AV decoder unit 24 into an NTSC standard video signal and outputs the video signal. For example, FIG.
In the case of the time setting shown in FIG. 7, even if the user selects any of the copy guard warning methods, the time is set from 18:10 to 1
Recording is performed separately until 8:40 and from 18:55 to 19:00.

As described above, in the broadcast receiving apparatus according to the fifth embodiment of the present invention, before the program information to be referred arrives, the reservation setting means sets the reserved time zone designated by the external input and the copy guard warning notification method. Set a reservation by
When the program information arrives, the reservation data creation means uses the program information to determine the reservation start time, reservation end time, and whether or not the program is a copy guard program in the set reservation time zone. From the obtained program, a program-specific reservation data is created together with the designated copy guard warning notification method if the program is a copy guard program, and the EPG control means generates a program-specific reservation data according to the program-specific reservation data. When the reservation start time arrives according to the program-specific reservation data, the reservation executing means instructs the selection of the reserved program and executes the reservation. In the case of a program, the recording reservation is not instructed to select the reserved program even when the reservation start time has arrived, so the user has not received the program information of the program to be reserved. At this point, you can not only specify a time zone and make a reservation, but also select a copy guard warning notification method so that if the program scheduled to be broadcast in the set reservation time zone is a copy guard program, it will be selected. A warning screen is displayed according to the copy guard warning notification method, and the user can know that a reservation that cannot be recorded has been set and change the reservation setting.

The above-mentioned warning notification method includes a method of not giving a warning, a method of displaying a warning message when a screen scheduled to be broadcast in a reserved time zone is determined to be a copy guard program, and then displaying a screen. When the program guide is displayed after it is determined that the program is a copy guard program, it is assumed that a warning screen is displayed on the program guide, so the user must select an appropriate warning notification method. If you select the one that displays the warning message, you can notify the warning with a higher probability.If you select the one that displays the warning screen on the program guide, you will be notified when the user's attention is high It is possible.

A second method of correcting a few minutes before the above, when the obtained broadcast start time or broadcast end time (program break time) is within a certain time from the set reservation start time, the set reservation start time is When the break time of the program is within a certain time from the set reservation end time, the set reservation end time is changed to the break time of the program within the certain time. A third method for correcting, and a fourth method for correcting the reservation start time from several seconds to several minutes before after the correction by the third method.
The user can select a desired correction method from various correction methods, select the first method, execute a reservation as set, and select the second method. Then, the user can view a completely displayed program or the like from the broadcast start time, select the third method, and set, for example, only 5 minutes from the reservation start time or the reservation end time set by the user.
For a program whose broadcast starts or ends with a difference of about a minute, it is possible to view the entire program or avoid reservation of a program that allows only a small part of the program to be viewed. Thus, there is an effect that the effects of the second and third methods can be obtained together.

[0093] According to the broadcast receiving apparatus of the present invention (claim 7), in the broadcast receiving apparatus according to claim 1, the reservation setting means adds a PPV purchase method designated by an external input and reserves. Is set, and from the program information, information as to whether or not the program scheduled to be broadcast in the set reservation time zone is a PPV program is obtained. In addition to the separate reservation data, when the reservation start time arrives according to the program-specific reservation data, when the reservation start time arrives, if the reservation start time arrives for a program selected as a PPV program not to be purchased. Since it is assumed that the reservation of the program to be reserved is instructed and the reservation is not executed, the user can designate and reserve the time zone when the program information of the program to be reserved has not arrived. In addition, by selecting the PPV purchase method, even if the program scheduled to be broadcast in the set reservation time zone is a PPV program, the reservation is executed and the PPV program is purchased according to the selected PPV purchase method. In addition, there is an effect that the user can cancel the reservation and not purchase it.
