Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a digital broadcast receiving apparatus according to an example of a program guide display device and a program reservation processing device of the present invention.

The digital broadcast receiving apparatus includes an antenna 1, a tuner 2, an MPU 3, a memory 4, an IR transmitting section 5, an IR receiving section 6, a keyboard 7, a VTR 8, a remote controller 9, a video encoder 10, a display device 11, and the like. ing.

The antenna 1 receives a broadcast wave of a digital broadcast. The tuner 2 has a decoding function, and selects a channel specified by the remote controller 9 from a broadcast wave received by the antenna 1. The MPU 3 controls the entire digital broadcast receiving device. The memory 4 is backed up by a power supply, and stores information related to reservation of various programs and programs.

The IR transmitting section 5 transmits various control signals such as recording or reproduction to the VTR 9. IR receiver 6
Receives various control signals such as recording or playback transmitted from the remote controller 9. The keyboard 8 receives various instructions such as recording or playback from the user by key input,
The received various instructions are transmitted to the MPU 3. VTR9
Based on various control signals transmitted from the IR transmitting unit 5, various information such as video and audio are recorded on a predetermined recording medium, and various information recorded on the predetermined recording medium are reproduced. The predetermined recording medium is a video tape, an optical disk, or the like. The remote controller 9 receives various instructions such as recording or reproduction from a user by button input, and transmits the received various instructions to the IR receiving unit 6.

The video encoder 10 demodulates the signal of the channel selected by the tuner 2 and provides a program image. The display device 12 is, for example, a CRT and displays a program video demodulated by the video encoder 10.

Hereinafter, the program reservation processing in the digital broadcast receiving apparatus described above will be described with reference to the flowchart shown in FIG. 3 and each reservation screen shown in FIGS.

The digital broadcast received by the digital broadcast receiving device contains program information and control information. Each program included in the program information has a program unique number (event i
d) is assigned, and each program can be identified by this program unique number (hereinafter, program ID). For example, when a specific program is reserved (recording reservation or viewing reservation), recording reservation or viewing reservation of the specific program is realized by designating a program ID assigned to the specific program. Note that the recording reservation is a reservation for recording a target program, and the viewing reservation is a reservation for viewing the target program. That is, in the case of the viewing reservation, the target program is displayed on the display device in synchronization with the broadcast start time of the target program.

The above-mentioned control information includes information on an electronic program guide (EPG) indicating a program schedule of each channel and the like. In addition, if necessary,
By including ancillary information indicating that the program schedule can be changed in the electronic program guide, a reservation corresponding to a fluid program schedule can be realized. The possibility of changing the program schedule includes the possibility of canceling the program, the possibility of interrupting the program, the possibility of postponing the program, the possibility of extending the program, and the like. That is, a program such as a sports broadcast may be canceled in the rain, suspended in the rain, delayed in the rain, or the like, and the broadcast time may be extended depending on the game development.

As described above, the tuner 2 not only selects each program from the program information contained in the digital broadcast broadcast wave but also extracts the control information contained in the digital broadcast broadcast wave. Further, the tuner 2 extracts an electronic program guide or an electronic program guide with additional information from the control information (ST1), and displays it on the display device 11 via the video encoder 10 as shown in FIG. Alternatively, the electronic program guide G2 is displayed (ST
2). That is, the tuner 2 functions as an extraction unit, and the display device 11 functions as a display unit.

As shown in FIG. 2, the program schedule of each channel is displayed in the electronic program guide G1 with attached information and the electronic program guide G2. Also, the electronic program guide G1 and the electronic program guide G2 with the attached information
As shown above, each program on each channel
A program ID is assigned. For example, 1 of channel 2 (CH2) on the electronic program guide G1 with attached information
A baseball broadcast scheduled to be broadcast from 9:00 to 21:00 is assigned “event id = 22” as a program ID. Further, information of “possibility of cancellation” is added to the baseball broadcast as additional information. The attached information may be displayed by characters as illustrated, or may be displayed by a mark / logo such as an icon. Further, the information may be displayed in the background color of the program column to which the additional information is added. That is, it is only necessary that the viewer be clearly informed that the baseball broadcast may change the program schedule.

The reservation of the program is advanced by operating the remote controller 9 as a reservation means, and the reserved contents are stored in the memory 4. The contents of the reservation stored in the memory 4 are executed under the control of the MPU as the reservation executing means. For example, the remote controller 9 is provided with a reservation mode key, a cursor movement key, and an enter key (not shown). When the reservation mode key is pressed, the reservation mode is executed (S
T3, YES), a cursor is displayed in a predetermined program column on the electronic program guide with attached information G1. At this time, when the cursor movement key is pressed, the cursor displayed in a predetermined program column on the electronic program guide with attached information G1 moves to another program column. When the enter key is pressed while the cursor is displayed in the target program column to be reserved,
The target program is selected as a reservation target (ST5), and the program ID assigned to the selected target program is stored in the memory 5 as program reservation information. If the reservation mode has not been executed (ST3, NO), other processing (ST4)
Then, the description of this is omitted.

When a program without attached information is selected from the electronic program guide with attached information G1 (ST6, N
O) The process proceeds to the normal reservation process (ST7), but the description thereof is omitted. Electronic program guide G with attached information
It is assumed that a program with attached information, for example, the above-described baseball program is selected from 1 (ST6, YES). At this time, the screen of the display device 11 displays the electronic program guide G1 with attached information.
Is switched to the reservation screen 1 shown in FIG.

As shown in FIG. 4, the reservation screen 1 displays the selected and determined channel, program name, broadcast time zone, and the like. Further, when the supplementary information is added to the selected program, the supplementary information is also displayed. For example, ancillary information is displayed, such as "This program may have its program schedule changed. Please be careful." Further, with the display of the attached information, a scheduled program reservation button for receiving a reservation of a scheduled program as originally scheduled to be broadcasted when the program schedule is not changed, and an alternative broadcasted when the program schedule is changed. An alternative program reservation button for accepting program reservation is displayed. Further, a guide for asking whether to reserve a scheduled program or an alternative program is displayed.

Here, a case where a scheduled program is reserved will be described. To reserve a scheduled program, a scheduled program reservation button is selected. Accordingly, the reservation screen 1 shown in FIG.
Is switched to the reservation screen 2 shown in FIG. As shown in FIG. 5, on the reservation screen 2, the selected channel, the program name, the broadcast time zone, and the like are displayed. Also, attached information is displayed. For example, "This program may change its program schedule. Please be careful."
And "Appointment may not be executed if program schedule is changed". In addition, a viewing reservation button that accepts viewing reservations,
A recording reservation button for accepting a recording reservation and a cancel button for canceling the reservation are displayed. When the viewing reservation button or the reservation recording button is selected, the reservation setting of the scheduled program is completed (ST8, YES).

Thereafter, if there is no change in the program schedule (ST9, NO), that is, if the scheduled program is broadcast as scheduled, the set reservation (recording reservation or viewing reservation) is executed (ST12). To change the program schedule,
It is detected by the PU 3 and the memory 4. As described above, the memory 4 stores the program ID to be reserved (here, the program ID of the scheduled program) as the program reservation information. If the program ID is not detected from the broadcast wave even when the scheduled time comes, it is determined that the program schedule has been changed. Conversely, if this program ID is detected from the broadcast radio wave at the scheduled time, it is determined that the program schedule has not been changed.

Even if the program schedule is changed (ST
(9, YES), if the reserved scheduled program is broadcast in the changed time zone (ST10, YES), the set reservation (recording reservation or viewing reservation) is executed (ST12). Since the reserved scheduled program is reserved by the program ID, even if the broadcast time of the reserved scheduled program changes, the program I
By detecting D, the reservation of the reserved scheduled program can be executed.

However, if the program ID of the reserved scheduled program is not detected during the detection period by separating the program ID detection period of the reserved scheduled program, the scheduled program will not be broadcast at the change time. (ST10, N
O), the reservation is canceled (ST11). in this way,
By reserving a scheduled program by a program ID, it is possible to cope with a flow schedule of a program schedule such as extension or deferment of a program.

Next, a case where an alternative program is reserved will be described. To reserve an alternative program, an alternative program reservation button is selected from the reservation screen 1 shown in FIG. 4 (ST1).
3, YES). Accordingly, the reservation screen 1 shown in FIG. 4 is switched to the reservation screen 3 shown in FIG. As shown in FIG.
The reservation screen 3 displays which program of which channel and which broadcast time zone of which program is to be reserved. Further, guidance such as "reservation is executed only when the program schedule of the scheduled program is changed" and "Please select a reservation setting method" are displayed. Further, a same time slot reservation button for designating a reservation for the same time slot as the scheduled program and a button for selecting a genre for reserving only an alternative program corresponding to a predetermined genre are displayed.

When the same time zone reservation button is selected from the reservation screen 3, the reservation screen 3 shown in FIG. 6 is switched to the reservation screen 4 shown in FIG. As shown in FIG. 7, the reservation screen 4 includes:
The display shows which program of which channel and which broadcast time slot of which program is to be reserved. Further, guidance such as "alternate program in the same time zone" and "reservation is executed only when the program schedule of the scheduled program is changed" are displayed. In addition, a viewing reservation button that accepts viewing reservations,
A recording reservation button for accepting a recording reservation and a cancel button for canceling the reservation are displayed. When the viewing reservation button or the reservation recording button is selected, the reservation setting of the alternative program by specifying the time zone is completed (ST14, YES).

Thereafter, if the program schedule is not changed (ST15, NO), that is, if the scheduled program is broadcast as scheduled, the set reservation (recording reservation or viewing reservation) is canceled (ST16). Conversely, if there is a change in the program schedule (ST15, YES), that is, if the scheduled program is not broadcast as scheduled, the set reservation (recording reservation or viewing reservation) is executed (ST12). By executing the reservation in the same time zone as the scheduled program, the reservation of the alternative program is executed. To change the program schedule,
As described above, it is detected by the MPU 3 and the memory 4. As described above, the memory 4 stores the program ID to be reserved as the program reservation information. Since the program ID of the substitute program is unknown, the program ID of the scheduled program is stored. If the program ID is not detected from the broadcast wave even when the scheduled time comes, it is determined that the program schedule has been changed. Conversely, if this program ID is detected from the broadcast wave at the scheduled time,
It is determined that the program schedule has not been changed.

When the selection button for the genre is selected from the reservation screen 3, the reservation screen 3 shown in FIG. 6 is switched to the reservation screen 5 shown in FIG. As shown in FIG. 8, the reservation screen 5 displays which program of which channel and which broadcast time zone of which program is to be reserved. Further, guidance such as "select by genre" and "select genre" is displayed. Further, a genre list is also displayed. A desired genre is selected by operating the cursor movement key and the enter key of the remote controller 9. For example, assume that a drama is selected. Then, the reservation screen 5 shown in FIG. 8 is switched to the reservation screen 6 shown in FIG.

The reservation screen 6 displays which program of which channel and which broadcast time zone of which program is to be reserved. Further, guidance such as "select by genre", "drama", and "reservation of a substitute program of the applicable genre is executed only when the program schedule of the scheduled program is changed" is displayed. Further, a viewing reservation button for receiving a viewing reservation, a recording reservation button for receiving a recording reservation, and a cancel button for canceling the reservation are displayed. When the viewing reservation button or the reservation recording button is selected, the reservation setting of the alternative program by specifying the genre is completed (ST17, YE).
S).

Thereafter, if the program schedule is not changed (ST18, NO), that is, if the scheduled program is broadcast as scheduled, the set reservation (recording reservation or viewing reservation) is canceled (ST16). Conversely, if the program schedule is changed (ST18, YES) and a program ID corresponding to the specified genre is detected (ST19, YE
S), the set reservation (recording reservation or viewing reservation) is executed (ST20). Even if there is a change in the program schedule (ST18, YES), if no program ID corresponding to the specified genre is detected (ST19, NO), the set reservation (recording reservation or viewing reservation) is canceled (ST16). ).

Incidentally, the control information of the broadcast wave includes the program I
Information indicating the relationship between D and the genre is included, and based on this information, it is determined whether or not the program ID detected from the broadcast radio wave corresponds to the specified genre.

The above description is based on the premise that the program ID of the alternative program is unknown. That is, since the program ID of the alternative program cannot be specified, the alternative program is specified by the time zone or by the genre. When specified by genre, only the alternative program corresponding to the genre desired by the user can be reserved. Further, when a plurality of programs are broadcast as alternative programs by designating by genre, the alternative programs not corresponding to the specific genre are excluded from the reservation target, and only the alternative programs corresponding to the specific genre are reserved. You can also. Furthermore, by designating by genre, an alternative program is indirectly reserved by a program ID. Accordingly, it is possible to cope with a flow composition such as extension or deferral of an alternative program.

Further, the present invention is not limited to the above-described method of designating an alternative program. When the program ID of the alternative program is known, for example, when the accessory information includes the program ID of the alternative program, the alternative program may be directly designated by the program ID. As a result, it is possible to execute a more accurate alternative program reservation.
