Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording reservation device and a program guide data creation device that are suitable when program data and program guide data are broadcast.
[0002]
[Prior art]
In recent years, digitalization of television broadcasting has been rapidly progressing. Digital broadcasting using communication satellites (CS) such as Perfect TV (SkyPerfec) has already started, digital broadcasting by broadcasting satellite (BS) is planned from 2000, and digital broadcasting by terrestrial is planned from 2003. ing.
[0003]
In digital broadcasting, program additional information such as program guide data (EPG) is transmitted in addition to program data. The program guide data includes data such as program broadcast time, channel, performer, and genre. By using the program guide data, it is also possible to search for a desired program from among multi-channel programs and automatically record a program that matches a favorite genre or performer without a user's recording reservation instruction. become.
[0004]
There has also been proposed a program table data format called a program group index in which a plurality of programs are grouped and information about the group is described. The current VTR has a function to reserve recording of continuous programs broadcasted at the same time every week. However, the user must perform a recording reservation operation for recording reservations of continuous programs whose broadcast dates and times are not constant. It was. By using the program group index, it is possible to make a recording reservation all at once by describing the broadcast date and time of each time in the program group index even for a continuous program whose broadcast date and time is not constant.
[0005]
By the way, when a continuous program starts to be recorded in the middle, a past program has already been broadcast and cannot be recorded. However, as the number of channels increases due to the spread of digital broadcasting, it is expected that the number of re-broadcasts of the same program will increase in the future. Therefore, by recording a rebroadcast program, it becomes possible to record a continuous program broadcast in the past. However, the user has to find out whether or not the rebroadcast program is broadcast and when it is broadcast, and make a recording reservation.
[0006]
In some cases, a digest program of a continuous program broadcast in the past may be broadcast in the future. Even in this case, the user has to find out whether or not the digest program is broadcast and when it is broadcast.
[0007]
[Problems to be solved by the invention]
In this way, when trying to record all the continuous programs, the already broadcasted programs cannot be recorded, but if a rebroadcast of a past program is broadcast in the future, all the continuous programs are recorded by recording the rebroadcast program. It becomes possible to record. However, there is a problem that the user has to find out when the rebroadcast program is broadcast and make a recording reservation.
[0008]
Further, even when a digest program of a continuous program broadcast in the past is broadcast in the future, the user himself has to find out when the digest program is broadcast and make a recording reservation.
[0009]
The present invention has been made to solve such problems. When a plurality of programs belonging to the same group, such as a continuous program, are recorded in a lump, the broadcast has already been completed and recorded. When there is no program, based on the information related to the related program of the program described in the program guide data, when the related program can be reserved for recording, the related program can be reserved for recording. An object is to provide an apparatus.
[0010]
Another object of the present invention is to provide a recording reservation apparatus, wherein the related program is a rebroadcast program.
[0011]
It is another object of the present invention to provide a recording reservation apparatus, wherein the related program is a digest program.
[0012]
[Means for Solving the Problems]
The recording reservation apparatus according to the present invention includes a receiving means for receiving broadcast program data and program guide data, a recording control means for controlling recording of the program data, and a management for managing the recorded program data. Means for inputting a recording reservation request by a user and receiving the request, and a function for batch recording recording of a plurality of programs belonging to the same group as the request for the program guide data, If there is a program in the group that has already been broadcast at the time of the request and is not recorded , the digest is based on information about the digest program of the group of the program described in the program guide data. it is characterized in that it comprises a recording reservation control means for recording reservation of the digest program if the program is available recording reservation

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0014]
FIG. 1 is a block diagram showing an embodiment of a recording / playback apparatus according to the present invention.
[0015]
The recording reservation apparatus 1 is an apparatus for reserving recording of program data transmitted by broadcasting using terrestrial waves, satellites, cables or the like as a medium.
[0016]
The program data receiving unit 2 receives program data transmitted by broadcasting. The program data receiving unit 2 outputs the received program data to the program data recording control unit 4 when recording the program data, and outputs the received program data to the program data when outputting to an external device such as a television. The data is output to the output unit 10. A plurality of program data receiving units 2 may be provided. The program data output unit 10 receives program data from the program data reception unit 2 and the program data reproduction unit 6, and outputs a video signal based on the program data to an external display device (not shown) such as a television receiver. Yes.
[0017]
The program guide data receiving unit 3 receives program guide data sent from broadcast, the Internet, or the like. The received program guide data is supplied to the program guide data output unit 11. The program guide data output unit 11 outputs a video output for displaying a program guide based on the input program guide data on an external display device such as a television receiver.
[0018]
The program data recording control unit 4 is for controlling recording of program data. When the recording reservation start time comes or when a recording request is received from the user, the program data recording control unit 4 records the program data from the program data receiving unit 2 in the program data storage unit 5. When a plurality of program data receiving units 2 are provided, the program data recording control unit 4 may record a plurality of input program data in the program data storage unit 5 at the same time.
[0019]
The program data storage unit 5 is composed of a recording medium such as a hard disk, an optical disk, or a video tape. The program data storage unit 5 is managed by the program data management unit 7 to store the program data, and the stored program data is read and output to the program data reproduction unit 6.
[0020]
The program data reproduction unit 6 is for reproducing program data. When the program data reproduction unit 6 receives a reproduction request from the user, the program data reproduction unit 6 inquires the program data management unit 7 where the program data to be reproduced exists in the program data storage unit 5. The program data management unit 7 gives the position of program data to be reproduced to the program data reproduction unit 6. The program data reproduction unit 6 reads the program data from the program data storage unit 5 by designating the position of the program data to be reproduced. The program data reproduction unit 6 outputs the read program data to the program data output unit 10.
[0021]
The program data management unit 7 manages the recorded program data, and when a reproduction request is generated, the recorded program data stored in the program data storage unit 5 can be designated and reproduced according to the reproduction request. It is supposed to be.
[0022]
The recording reservation control unit 8 receives a recording reservation request from the user input unit 9 and sets a recording reservation. When the recording reservation start time comes, an instruction to start recording is given to the program data receiving unit 2 based on the recording reservation. The program data receiving unit receives a program based on the recording reservation and outputs it to the program data recording control unit 4. The program data recording control unit 4 outputs the input program data to the program data storage unit for storage.
[0023]
The user input unit 9 interprets a user input sent from a remote controller or the like and outputs a necessary request to each unit. That is, the user input unit 9 gives a request to the program data receiving unit 2 when receiving program data, and gives a request to the program guide data receiving unit 3 when receiving program guide data, and immediately records. In this case, a request is given to the program data recording control unit 4, a request is given to the program data reproduction unit 6 for reproduction, and a request is given to the recording reservation control unit 8 for recording reservation. Yes.
[0024]
FIG. 2 is an explanatory diagram for explaining an example of program guide data.
[0025]
As shown in FIG. 2, the program guide data includes information on items such as program ID, group ID, channel, program name, broadcast date, start time, end time, program content, and genre. The program ID is an ID unique to the program, and the program guide is managed for each program ID. The group ID is an ID for indicating a grouped program such as a continuous program or a series.
[0026]
FIG. 3 shows an example of displaying the program guide data on a display device such as a television. The vertical axis indicates the time, and the horizontal axis indicates the channel. In this embodiment, the program guide data from 18:00 to 21:00 on April 15, 2, 5, and 7 channels are displayed. By selecting a program from the displayed program guide data with an input device such as a remote controller, it is possible to change the channel or make a recording reservation.
[0027]
FIG. 4 shows an example of the program guide data of the grouped programs. Programs whose program name is “Battle Talk” form one group. The group ID is 5002, which means that broadcasts are performed from 19:00 to 20:54 every week from April 8. The program guide data of the grouped program has the number of broadcasts and the related program ID in addition to the program guide data items shown in FIG. The number of broadcasts indicates the number of broadcasts from the first time such as a continuous program. The related program ID indicates a link to the program when there is a related program. “Battle Talk” broadcast from 19:00 to 20:54 on April 8 has a related program ID of 51502, and “Program Review” broadcast from 10:00 to 12:00 on April 16 is related. It shows that it is a program.
[0028]
FIG. 5 also shows an example of the program guide data of the grouped programs. Programs whose program name is “program review” form one group. The group ID is 5501, which is broadcast every week from April 9th from 10:00 to 12:00. As shown in FIG. 5, a plurality of related program IDs may be held.
[0029]
Next, the operation of the first embodiment will be described with reference to the flowchart of FIG .
[0030]
FIG. 6 shows an operation flow when the user requests group recording reservation for a program. In this embodiment, a recording reservation is made based on the program guide data and the grouped program guide data shown in FIGS.
[0031]
The program guide data output unit 11 outputs the program guide data to a display device such as a television (step S1). The user operates the remote controller to select a program to be reserved for recording from the displayed program guide data (step S2). Here, it is assumed that “Health Hot Rin” broadcast from 20:00 to 21:00 on the 2nd channel on April 15 is selected. In addition, the recording reservation operation is performed at 15:00 on April 15. The user input unit 9 receives a recording reservation request for the selected program from the remote controller, and notifies the recording reservation control unit 8 of the recording reservation.
[0032]
The recording reservation control unit 8 sends a screen display request for selecting the type of recording reservation to the program guide data output unit (step S3). FIG. 7 shows an example in which a screen for selecting a recording reservation is output to a display device such as a television. There are two types of recording reservations: normal recording reservation for recording only the specified program, and group recording reservation for recording all programs in the group to which the specified program belongs.
[0033]
When the normal recording reservation is selected, a recording reservation request for only the designated program is sent from the user input unit 9 to the recording reservation control unit 8. The recording reservation control unit 8 sets the recording reservation for the designated program and ends (step S4).
[0034]
When the group recording reservation is selected, a group recording reservation request is sent from the user input unit 9 to the recording reservation control unit 8. The recording reservation control unit 8 receives program guide data related to the group program to which the designated program belongs from the program guide data receiving unit 3. The recording reservation control unit 8 checks whether there is a group recording target program from the program guide data related to the group program (step S5). In this embodiment, a “battle talk” program with a group ID of 5002 is targeted. It can be seen from the program table data relating to the group program in FIG. 4 that these programs are broadcast every week from April 8 to 19:00 to 20:54. The following processing is performed on the program to be group-recorded.
[0035]
The recording reservation control unit 8 checks whether the program has already been broadcast (step S6). In the case of a program to be broadcast in the future, a recording reservation for the program is set (step S7). In this embodiment, the group recording reservation operation is performed at 15:00 on April 15th, so the broadcasts after April 15th are programs that will be broadcast in the future.
[0036]
If the program has already been broadcast, the recording reservation control unit 8 inquires of the program data management unit 7 whether or not the program has been recorded (step S8). In the present embodiment, the program broadcast on April 8 is already broadcast.
[0037]
If it has not been recorded, the recording reservation control unit 8 checks whether there is a program related to the program from the program guide data related to the group program in FIG. 4 (step S9). In this embodiment, since the related program ID of “Battle Talk” broadcasted on April 8 is 51502, it can be seen that there is a related program, and from FIG. It turns out that it is a “program review” broadcast from 10:00 to 12:00 on the day.
[0038]
The recording reservation control unit 8 checks whether or not recording reservations overlap at the time when the related program is broadcast (step S10). If the recording reservation is not duplicated and the recording reservation is possible, the recording reservation of the related program is set (step 11).
[0039]
As a result, if a past program has not been recorded because a continuous program has started to be recorded in the middle, if the related program of the past program is broadcast in the future and recording reservation is possible, the related program is reserved for recording. This makes it possible to record a related program of a past program that has not been recorded.
[0040]
Next, the operation of the second embodiment will be described with reference to the flowchart of FIG. In this embodiment, the program schedule data shown in FIG. 2, FIG. 9 and FIG. 10 and the program schedule data are grouped to make a recording reservation based on the program schedule data. FIG. 9 shows an example of the program table data of the grouped programs and the related program is a rebroadcast program. Programs whose program name is “Health Hot Lein” form a group. The group ID of this group program is 2003, which is broadcast from 23:00 to 21:00 every day from April 13th to April 17th. Further, by examining the item of the rebroadcast program ID, it can be seen that each rebroadcast is broadcast as a rebroadcast ID 20203, 21203, 22203, 23203, 24203 . FIG. 10 also shows grouped program guide data in which rebroadcast programs of “Health Hotraiin” whose group ID is 2003 are grouped. This group ID is 2103, which is broadcast every day from April 20th to April 24th from 14:00 to 15:00 (but only from April 22 from 15:00 to 16:00) It has a value different from the group ID 2003 .
[0041]
FIG. 8 shows an operation flow when a user requests recording reservation for a group program.
[0042]
Steps S21 to S28 are the same as steps S1 to S8 in the flowchart shown in FIG.
[0043]
If it has not been recorded, the recording reservation control unit 8 checks whether there is a rebroadcast program from the program guide data relating to the group program in FIG. 9 (step S29). In the present embodiment, the rebroadcast of the program broadcast from 20:00 to 21:00 on April 13 is from 14:00 to 15:00 on April 20, and from 20:00 to 21:00 on April 14. It can be seen that the rebroadcast of the broadcasted program is broadcast from 14:00 to 15:00 on April 21.
[0044]
The recording reservation control unit 8 checks whether or not recording reservations overlap at the time when the rebroadcast program is broadcast (step S30). If the recording reservation is not duplicated and the recording reservation is possible, the recording reservation of the rebroadcast program is set (step 31).
[0045]
As a result, if a past program has not been recorded because a continuous program has started to be recorded in the middle, a re-broadcast program can be reserved if a re-broadcast program of the past program is broadcast in the future and recording reservation is possible. By doing so, it becomes possible to record a rebroadcast program of a past program that has not been recorded.
[0046]
Next, the operation of the third embodiment will be described with reference to the flowchart of FIG. In this embodiment, a recording reservation is made based on the program guide data and the grouped program guide data shown in FIGS. FIG. 12 shows an example in which the program guide data of the grouped programs and the related program is a digest program. Programs whose program name is “local document” form one group. This group program has a group ID of 2001, and is broadcast from 18:00 to 19:00 every day from April 13 to April 17. Further, by examining the item of the digest program ID, it can be seen that the digest program whose digest ID (main broadcast ID) is 20201 is broadcast from 14:00 to 16:00 on April 29 as shown in FIG. .
[0047]
FIG. 11 shows an operation flow when the user requests group recording reservation for a program.
[0048]
Steps S41 to S48 are the same as steps S1 to S8 in the flowchart shown in FIG.
[0049]
If it has not been recorded, the recording reservation control unit 8 checks whether there is a digest program from the program table data related to the group program in FIG. 12 (step S49). In this embodiment, the digest broadcast of a program broadcast from 18:00 to 19:00 every day from April 13 to April 17 is from April 14:00 to 16:00 as shown in FIG. I understand that it will be broadcast.
[0050]
The recording reservation control unit 8 checks whether or not the recording reservations overlap at the time when the digest program is broadcast (step S50). If the recording reservation is not duplicated and the recording reservation is possible, the recording reservation for the digest program is set (step 51).
[0051]
As a result, if a past program has not been recorded because a continuous program has started to be recorded in the middle, and the digest program of the past program is broadcast in the future and can be reserved for recording, the digest program should be reserved for recording. This makes it possible to record a digest program of a past program that has not been recorded.
[0052]
【The invention's effect】
As described above, according to the present invention, related to the case where recording a continuous program from the middle does not record a past program, if the related program of past programs is recordable is then broadcast reserved By making a recording reservation for a program, it becomes possible to record a related program of a past program that has not been recorded. That is, according to the present invention, when a continuous program is recorded from the middle and a part of the past program is not recorded, or even if a rebroadcast program of the past program is subsequently broadcast, a part of the program is recorded. If you were not, because the digest program of past programs to recording reservation the digest program, if possible recordings are then broadcast reservation, to be capable of recording the digest program of past programs that were not recorded Become.
