Then, a reservation information updating unit 22 updates reservation information.

Description

  The present invention relates to a broadcast program reserved recording apparatus that reserves a program such as digital television broadcast and records it on a storage medium.

  In a conventional broadcast program reserved recording apparatus, when an instruction to reserve recording of a program that is broadcast multiple times such as every week or every day (hereinafter sometimes referred to as “multiple broadcast programs”) is input, Program information of a program for which reservation is instructed is acquired from the program data and stored. The program information includes broadcast start time information and broadcast end time information. Recording of a program is reserved based on broadcast start time information and broadcast end time information in the acquired program information.

  In a multi-broadcast program, the broadcast start time and broadcast end time (hereinafter sometimes collectively referred to as “broadcast time”) may fluctuate. When the broadcast time changes, there is a problem that the user needs to correct the reservation.

  As a technique for solving this problem, the next program is based on one or both of the broadcast start time information and the broadcast end time information stored in the program information stored on the next broadcast date. There is a technique for searching for and updating a reservation (see, for example, Patent Document 1).

Japanese Patent No. 3856288 (paragraph 0012)

  As described above, the technique disclosed in Patent Document 1 searches for the next program and updates the reservation. This eliminates the need for the user to correct the reservation every broadcast time, thereby improving the usability of the broadcast program reserved recording apparatus.

  However, in the technique disclosed in Patent Document 1, an electronic program guide (Electronic Program Guide) is used so that a user can make a recording reservation as broadcast start time information and broadcast end time information, which is a reference for searching for the next program. Broadcast start time information and broadcast end time information of a program on a broadcast day selected from Guide (abbreviation: EPG) are used.

  Therefore, if the broadcast time period is different between the reserved broadcast program and the next and subsequent programs, there is a problem that the next and subsequent programs cannot be detected correctly. For example, if the broadcast date selected by the user is the first broadcast of a multiple-time broadcast program and the broadcast time zone is significantly different from the next program, the program to be broadcast next time will be detected correctly. There is a problem that you can not.

  Thus, if the next and subsequent programs cannot be detected correctly, the reservation will not be corrected correctly, and a program different from the program reserved by the user may be recorded.

  An object of the present invention is to provide a broadcast program reserved recording apparatus capable of accurately detecting the next and subsequent programs when recording of a program to be broadcast a plurality of times is reserved.

  The broadcast program reserved recording apparatus of the present invention includes broadcast date information representing broadcast dates of a plurality of programs scheduled to be broadcast, broadcast time zone information representing broadcast time zones, program title information representing titles, and program content information representing content. Program information acquisition means for acquiring program information including a predetermined number of days, and reservation information for recording a reservation target program that is a program instructed to be recorded by a user among the plurality of programs.

However, in the case of a multiple-time broadcast program that is broadcast a plurality of times, reference broadcast time zone information representing a reference broadcast time zone that is a broadcast time zone that serves as a reference for the multiple-time broadcast program is stored, and the reservation means From the program information acquired by the program information acquisition means, among the multiple-time broadcast programs, when the broadcast times after the next scheduled broadcast time, which is a broadcast time instructed to be recorded by the user, are detected. , Storing the broadcast time zone information of the reserved broadcast times or the next and subsequent broadcast times of the reserved broadcast times in the reserved information storage means as the reference broadcast time zone information, and for each broadcast time of the multiple-time broadcast program Every time recording is completed, the next broadcast times of the multiple broadcast programs are searched based on the reference broadcast time zone information stored in the reservation information storage means, and the detected program of the next broadcast times is searched. Affection The generates reservation information, and to store the reservation information storing means based on the.

  Further, in the broadcast program reserved recording apparatus of the present invention, the reservation means includes the broadcast time of the reserved broadcast times of the broadcast time zone information and the broadcast time zone information of the next broadcast time of the reserved broadcast times. The broadcast time zone information of the shortest broadcast time is stored in the reservation information storage means as the reference broadcast time zone information.

  Further, in the broadcast program reserved recording apparatus according to the present invention, the reservation means, based on the program information, the specified broadcast time in which the broadcast time zone of the reserved broadcast times is a predetermined broadcast time zone of the multiple-time broadcast program If the broadcast time zone of the reserved broadcast times is different from the specified broadcast time zone, the broadcast time zone information of the broadcast times after the next time of the reserved broadcast times is determined as the reference. It is stored in the reservation information storage means as broadcast time zone information.

  Moreover, in the broadcast program reserved recording apparatus of the present invention, the reservation means is based on whether the program title information or the program content information of the program information includes specific character string information representing a predetermined character string. It is determined whether a broadcast time zone of the reserved broadcast times is different from the specified broadcast time zone.

  According to the broadcast program reserved recording apparatus of the present invention, when the next broadcast times of the reserved broadcast times instructed to be recorded by the user are detected from the program information acquired by the program information acquisition means, the reservation is made. By the means, the broadcast time zone information of the reserved broadcast times and the next and subsequent broadcast times is stored in the reservation information storage means as the reference broadcast time zone information. For example, the broadcast time zone information of the broadcast time with the shortest broadcast time among the reserved broadcast times and the next and subsequent broadcast times is stored in the reservation information storage means as the reference broadcast time zone information. Then, every time recording of each broadcast time is completed, the next broadcast time is searched by the reservation means based on the reference broadcast time zone information stored in the reservation information storage means. Reservation information is generated by the reservation means based on the detected program information of the next broadcast time and stored in the reservation information storage means.

  Accordingly, it is possible to search for the next broadcast time using the broadcast time zone information of the next and subsequent broadcast times as the reference broadcast time zone information. For example, when the broadcast time zone of the reserved broadcast times has been changed to be longer than a predetermined standard broadcast time zone, the broadcast time zone information of the next and subsequent broadcast times that have not been changed is used as the reference broadcast time zone information. Can be used to search for the next broadcast times. Therefore, it becomes possible to accurately detect the next and subsequent programs, and the user-friendliness can be improved.

  Further, according to the broadcast program reserved recording apparatus of the present invention, the reservation means broadcasts the shortest broadcast time among the broadcast time zone information of the reserved broadcast times and the broadcast time zone information of the next and subsequent broadcast times of the reserved broadcast times. Broadcast time zone information is stored in the reservation information storage means as reference broadcast time zone information. As a result, the detection accuracy of the next program can be improved, so that the next and subsequent programs can be detected more accurately.

  Further, according to the broadcast program reserved recording apparatus of the present invention, the reservation means determines whether or not the broadcast time zone of the reserved broadcast times is different from the specified broadcast time zone based on the program information. When it is determined by the reservation means that the broadcast time zone of the reserved broadcast times is different from the specified broadcast time zone, the broadcast time zone information of the broadcast times after the next of the reserved broadcast times is set as the reference broadcast time zone information as the reservation information storage means Is remembered. As a result, the detection accuracy of the next program can be improved, so that the next and subsequent programs can be detected more accurately. Therefore, the user convenience can be further improved.

  According to the broadcast program reserved recording apparatus of the present invention, the broadcast time zone for the reserved broadcast times is defined by the reservation means based on whether the program title information or the program content information of the program information includes specific character string information. It is determined whether or not the broadcast time is different. As a result, the broadcast program reserved recording apparatus in which the detection accuracy of the next program is improved as described above can be realized with a simple configuration.

The output device 32 outputs video and audio based on the playback video / audio signal 45 provided from the AV decoder unit 15. As a result, the user can view the program recorded by the broadcast program reservation device 1.

  The program data extraction unit 16 extracts program data 47 from the table information 46 given from the transport stream decoder unit 12. The program data 47 includes program information. The program data extraction unit 16 gives the extracted program data 47 to the microcomputer unit 17.

  The microcomputer unit 17 gives the program data 47 given from the program data extraction unit 16 and an instruction to output the EPG based on the program data 47 to the output device 32 to the OSD unit 21 of the AV decoder unit 15. The OSD unit 21 of the AV decoder unit 15 generates an EPG to be output to the output device 32 in accordance with an instruction given from the microcomputer unit 17 and supplies the EPG to the output device 32.

  The user confirms the EPG displayed on the display screen of the output device 32, operates the reservation input device 33 such as a remote controller, and so on. Select Yes. Thus, a reservation instruction for recording the reservation target program is given from the reservation input device 33 to the microcomputer unit 17.

  When the reservation target program is a multiple-time broadcast program broadcasted a plurality of times, the user uses the reservation input device 33 to record only the current broadcast of the reservation target program, or this broadcast It is possible to select whether to record a reservation target program to be broadcast after this time.

  Examples of the multiple broadcast program include a continuous program and a series program. A continuous program refers to a program whose contents are continuous, such as a continuous drama. A series program is a program that is not continuously broadcast but is regularly broadcast with the same program title, such as a regular program. Here, it is assumed that a re-broadcast program having the same program title and the same content is not included in the multiple-time broadcast program.

  The microcomputer unit 17 executes a process for reserving recording of a program (hereinafter also referred to as “recording reservation process”) based on a reservation instruction given from the reservation input device 33. Specifically, the microcomputer unit 17 generates reservation information corresponding to the reservation instruction given from the reservation input device 33 and supplies it to the reservation information storage unit 18.

  The reservation information includes broadcast date information, broadcast time zone information, program title information, and channel information of a program reserved for recording. The broadcast time zone information includes broadcast start time information indicating the broadcast start time and broadcast end time information indicating the broadcast end time. The broadcast time zone information may include broadcast duration information representing the broadcast duration from the broadcast start time to the broadcast end time, instead of the broadcast end time information.

  When the reservation target program is a multiple-time broadcast program, the reservation information includes pattern information representing a repetition pattern of the broadcast date of the multiple-time broadcast program. The repeating pattern is, for example, a specific day of the week, such as every day, Monday to Friday, or every day of the week.

  The reservation information updating unit 22 of the microcomputer unit 17 includes an arithmetic processing device (Central Processing Unit; abbreviated as CPU) in the microcomputer unit 17 and an internal memory. A control program is stored in the internal memory. The function of the reservation information update unit 22 can be realized by executing a control program stored in the internal memory on the microcomputer unit 17.

  The reservation information storage unit 18 stores the reservation information given from the microcomputer unit 17 and appropriately gives it to the microcomputer unit 17. The reservation information storage unit 18 is realized by a nonvolatile memory.

  When the date and time specified by the broadcast date information and the broadcast time zone information included in the reservation information (hereinafter sometimes referred to as “reservation date and time”) is reached, the microcomputer unit 17 includes the digital tuner unit 11, the transport stream decoder unit 12, and The stream controller unit 13 is controlled directly or indirectly to cause the storage unit 14 to record the broadcast program.

  The program data 47 stores program information for 8 days or more, and the user can make a reservation from one week before the broadcast day. Moreover, the program data 47 is always transmitted from the broadcasting station, and the contents are updated as appropriate.

  The reservation information update unit 22 of the microcomputer unit 17 has a function of changing reservation information based on the program data 47 given from the program data extraction unit 16 (hereinafter sometimes referred to as “tracking recording function”). When the program data 47 is updated, the reservation information update unit 22 updates the reservation information stored in the reservation information storage unit 18 based on the updated program data 47. When the reservation information stored in the reservation information storage unit 18 is updated, the microcomputer unit 17 executes a recording process for the reserved program based on the updated reservation information.

  FIG. 2 is a diagram showing an example of a broadcast schedule of a reservation target program according to the first embodiment of the present invention. In FIG. 2, the program to be reserved is “program A”, and the broadcast schedule from 20:00 to 23:00 (20:00 to 23:00) of the channel on which the program A is broadcast is shown for each week. FIG. 2 (1) shows the broadcast schedule for the first week when the first broadcast 51 of program A is scheduled, and FIG. 2 (2) shows the broadcast schedule for the second week, which is the week after the first week. FIG. 2 (3) shows the broadcast schedule for the third week, which is the second week after the first week. In FIG. 2, hatched hatching is added to the time zone in which program A is broadcast.

  As shown in FIG. 2A, in the first week, the first broadcast 51 of program A is scheduled from 20:00 to 22:30 (20: 00 to 22:30). Here, the program A is a program that is broadcast a plurality of times on the same day of the week, and the second broadcast 52 of the program A with the same title is scheduled in the second week, which is the week after the first week, on the same channel. It is assumed that the third broadcast 53 of the program A having the same title is scheduled for the third week, which is the second week after the first week.

  As shown in FIG. 2 (2), in the second week, the second broadcast 52 of program A is scheduled from 21:00 to 22:00 (21: 0 to 22:00). As shown in FIG. 2 (3), in the third week, the third broadcast 53 of program A is scheduled from 21:00 to 22:00 (21:00 to 22:00).

  That is, the program A is normally broadcast in a time frame of 1 hour from 21:00 to 22:00 (21: 0 to 22:00), but the broadcast time is expanded only for the first broadcast 51, and the time is 2 hours 30 Broadcast in an extended time frame of minutes. In the first episode of a series program or series program such as a drama, there are many operations in which the time frame is expanded in this way.

  In FIG. 2 (2), the program B broadcasted from 20:00 to 21:00 (20:00 to 21:00) in the second week is indicated by reference numeral “54”. In FIG. 2 (3), the program C broadcast from 20:00 to 21:00 (20: 00 to 21:00) in the third week is indicated by reference numeral “55”.

  For example, let us consider a case where the user instructs reservation of recording of the first broadcast 51 of the program A shown in FIG. 2A based on the EPG, and further selects weekly reservation. In this case, in the broadcast program reserved recording apparatus 1, a recording reservation process is executed. Specifically, the recording reservation process is executed by the microcomputer unit 17.

  When the user gives an instruction to reserve recording of the first broadcast 51 of the program A, and further selects weekly reservation, the microcomputer unit 17 broadcasts based on the program information of the first broadcast 51 of the program A. Reservation information including start time information and broadcast end time information is generated, and the generated reservation information is given to and stored in the reservation information storage unit 18.

  Thereafter, the microcomputer unit 17 searches the program information for the next broadcast of the program A, here the second broadcast 52. When the microcomputer 17 detects the next broadcast of the program A as a result of the search, the next broadcast of the detected program A, here the broadcast time zone information including the broadcast start time information and the broadcast end time information of the second broadcast 52 Is given to the reservation information storage unit 18 as reference broadcast time zone information and stored.

  When the first broadcast 51 of the program A ends and the recording of the reserved first broadcast 51 is completed, the microcomputer unit 17 uses the reference broadcast time zone information previously stored in the reservation information storage unit 18. Based on this, the next broadcast of program A, here the second broadcast 52 is searched. When the microcomputer unit 17 detects the next broadcast of the program A as a result of the search, the reservation information update unit 22 performs the reservation information based on the detected next broadcast of the program A, here, the program information of the second broadcast 52. The reservation information stored in the storage unit 18 is updated. The microcomputer unit 17 executes the update operation of the reservation information every time the broadcast of the program A is finished and the reserved recording is completed.

  As described above, in the present embodiment, the second and subsequent broadcast time zone information is used as the reference broadcast time zone information serving as a reference for searching for program A. As a result, the next and subsequent reservations can be made in the normal broadcast time zone without being affected by the first broadcast time zone.

  For example, as shown in FIG. 2A, the first broadcast 51 of the program A may be an enlarged version that is broadcast with an extended broadcast time. In this case, when the broadcast time zone information indicating the broadcast time zone of the first broadcast 51 from 20:00 to 22:30 (20:00 to 22:30) is used as the reference broadcast time zone information, FIG. When searching for the program A of the second week shown in 2), the program B that starts at 20:00 (20:00) may be erroneously detected as the second broadcast 52 of the program A.

  In the next program search process, the program search accuracy is improved by comprehensively considering not only broadcast start time information and broadcast end time information but also program title information and genre information. be able to. However, every time the program search process is performed, there is a risk of erroneously detecting the program. For example, when searching for the program A of the third week shown in FIG. 2 (3), the program C starting at 20:00 (20:00) is erroneously detected as the third broadcast 53 of the program A. There is a risk that.

  In the example of FIG. 2, after making a reservation for recording the first broadcast 51 of the program A in FIG. 2 (1), the second broadcast 52 of the program A in FIG. 2 (2) is accurately detected once. If it is possible, in the subsequent program search process, the broadcast time zone information indicating the broadcast time zone of the second broadcast 52 of program A from 21:00 to 22:00 (21: 0 to 22:00) is used as the reference broadcast time zone information. Can be used as Thereby, the risk of erroneously detecting a program during the program search process can be reduced.

  FIG. 3 is a flowchart showing the processing procedure of the broadcast program reserved recording apparatus 1 relating to the recording reservation processing in the first embodiment of the present invention. Each process of the flowchart shown in FIG. 3 is executed by the microcomputer unit 17. The processing of the flowchart shown in FIG. 3 is started when a recording reservation instruction is input by the user via the reservation input device 33, and the process proceeds to step S1. Here, a case will be described in which the user selects the latest program A to be broadcast from the EPG and instructs the recording reservation using the reservation input device 33.

  In step S1, the microcomputer unit 17 determines whether or not the repeated reservation is selected by the user. If it is determined in step S1 that the repeated reservation is selected, the process proceeds to step S2. If it is determined that the repeated reservation is not selected, the process proceeds to step S9. For example, when the program A for which the user has instructed recording reservation is a multiple-time broadcast program broadcasted on the same day of the week, the user repeatedly schedules the recording reservation for the program A, for example, weekly reservation. Is selected, it is determined in step S1 that the repeated reservation has been selected, and the process proceeds to step S2.

  In step S <b> 2, the microcomputer unit 17 acquires the current program information regarding the program for which recording reservation is instructed, in this case, the program A, from the program data 47 provided from the program data extraction unit 16. The program information includes broadcast time zone information. The broadcast time zone information includes broadcast start time information and broadcast end time information. When the current program information is acquired, the process proceeds to step S3.

  In step S 3, the microcomputer unit 17 generates reservation information based on the broadcast time zone information included in the current program information acquired in step S 2, and stores the generated reservation information in the reservation information storage unit 18. Through the processing up to step S3, the recording reservation processing for the current program A to be broadcast most recently is once completed. When the reservation information is stored in the reservation information storage unit 18 in step S3, the process proceeds to step S4.

  In step S4, the microcomputer unit 17 stores the current broadcast time zone information of the program A in the reservation information storage unit 18 as reference broadcast time zone information. When the reference broadcast time zone information is stored in the reservation information storage unit 18, the process proceeds to step S5.

  In step S5, the microcomputer unit 17 searches for the next program A from the program data 47 given from the program data extraction unit 16 based on the reference broadcast time zone information stored in the reservation information storage unit 18 in step S4. Then, the process proceeds to step S6.

  The program data 47 includes, for example, information on broadcast programs for at least 8 days. The microcomputer unit 17 searches for the next program A using not only the broadcast start time information and the broadcast end time information included in the reference broadcast time zone information but also information such as the program title. Details of the search method for the next program A are omitted.

  In step S6, the microcomputer unit 17 determines whether or not the next program A is detected as a result of searching for the next program A in step S5. If it is determined in step S6 that the next program A has been detected, the process proceeds to step S7. If it is determined that the next program A has not been detected, all processing procedures are terminated.

  In step S <b> 7, the microcomputer unit 17 acquires program information related to the next program A from the program data 47 provided from the program data extraction unit 16. When the program information of the next program A is acquired, the process proceeds to step S8.

  In step S8, the microcomputer unit 17 stores the broadcast time zone information included in the next program information acquired in step S7 in the reservation information storage unit 18 as reference broadcast time zone information. Accordingly, the broadcast time zone information of the current program A stored in the reservation information storage unit 18 as the reference broadcast time zone information in step S4 is updated to the broadcast time zone information of the next program A. When the reference broadcast time zone information is stored in the reservation information storage unit 18, all processing procedures are terminated.

  If it is determined in step S6 that the next program A has not been detected and the processing procedure is terminated, the program A stored in the reservation information storage unit 18 as the reference broadcast time zone information in step S4. Broadcast time zone information is retained as it is.

  In step S9, as in step S2, the microcomputer unit 17 obtains the current program information for the program for which recording reservation is instructed, in this case, the program A, from the program data 47 given from the program data extraction unit 16. Then, the process proceeds to step S3.

  In step S10, as in step S3, the microcomputer unit 17 generates reservation information based on the broadcast time zone information included in the current program information acquired in step S9, and the generated reservation information is stored in the reservation information storage unit. 18 is stored. When the reservation information is stored in the reservation information storage unit 18, all processing procedures are terminated.

  FIG. 4 is a flowchart showing a processing procedure of the broadcast program reservation recording apparatus 1 regarding the recording reservation processing when the weekly reservation is selected in the first embodiment of the present invention. In FIG. 4, as a specific example of the recording reservation process, a process when the user selects a weekly reservation as a repeated reservation is shown. Each process of the flowchart shown in FIG. 4 is executed by the microcomputer unit 17.

  The process of each step of the flowchart shown in FIG. 4 corresponds to the process of steps S2 to S8 of the flowchart shown in FIG. In FIG. 4, each step is indicated by adding a subscript “a” to the step number of the corresponding step in FIG. The process of the flowchart shown in FIG. 4 is started when it is determined in step S1 shown in FIG. 3 that the repeated reservation is selected, and the process proceeds to step S2a.

  The next program search process in step S22 in FIG. 5 (hereinafter sometimes referred to as “next program search process”) may be the same as the next program search process in step S5 in FIG. 3 described above. However, the following points are different.

  In the next program search process in step S5 of FIG. 3 described above, the current broadcast time zone information of program A previously stored in the reservation information storage unit 18 in step S4, that is, the program A of the broadcast times reserved by the user. Broadcast time zone information is used as reference broadcast time zone information.

  On the other hand, in the next program search process of step S22 of FIG. 5, the broadcast time zone information of the next program A of the broadcast times reserved by the user is stored as the reference broadcast time zone information in step S8 of FIG. In this case, the broadcast time zone information of the next program A is used as the reference broadcast time zone information.

  As described above, in the present embodiment, in the next program search process of step S22 in the reservation information update process shown in FIG. 5, the broadcast time of at least the second and subsequent broadcast times of the program for which repeated reservation is selected, here, program A is used. The band information is used as reference broadcast time band information when the next program is detected. Thereby, the detection accuracy of the next program in the next program search process can be improved. Therefore, the usability of the user of the broadcast program reserved recording device 1 can be improved.

  More specifically, in the present embodiment, the broadcast times (hereinafter sometimes referred to as “reserved broadcast times”) instructed by the user to make a recording reservation from the program data 47 extracted by the program data extraction unit 16. When the next and subsequent broadcast times are detected, the microcomputer 17 stores the broadcast time zone information of either the reserved broadcast times or the next and subsequent broadcast times in the reservation information storage unit 18 as reference broadcast time zone information. Is done.

  For example, the broadcast time zone information of the shortest broadcast time among the reserved broadcast times and the next and subsequent broadcast times is stored in the reservation information storage unit 18 as the reference broadcast time zone information. In the present embodiment, since the reserved broadcast times are the first, the microcomputer unit 17 stores the broadcast time zone information of the second and subsequent broadcast times with a short broadcast time as the reference broadcast time zone information. Stored in the unit 18.

  The microcomputer unit 17 searches for the next broadcast time based on the reference broadcast time zone information stored in the reservation information storage unit 18 every time recording of each broadcast time is completed. When the next broadcast time is detected, the microcomputer unit 17 generates reservation information based on the detected program information of the next broadcast time and stores it in the reservation information storage unit 18.

  As described above, according to the present embodiment, it is possible to search for the next broadcast time using the broadcast time zone information of the next and subsequent broadcast times as the reference broadcast time zone information. For example, as in the present embodiment, when the first broadcast time zone, which is a reserved broadcast time, has been changed to be longer than a predetermined broadcast time zone, the next and subsequent times that have not been changed It is possible to search for the next broadcast time using the broadcast times, specifically, the second and subsequent broadcast time zone information as the reference broadcast time zone information.

  As a result, the accuracy of detecting the next program in the next program search process can be improved, so that the next and subsequent programs can be accurately detected. Therefore, the usability of the user of the broadcast program reserved recording device 1 can be improved.

  Further, in this embodiment, when the next program A cannot be detected in the next program search process in step S22 of FIG. 5 for some reason, the reference broadcast stored in the reservation information storage unit 18 in step S26. Recording is reserved according to the time zone information.

  At this time, if the broadcast time zone information of the next program A of the broadcast time reserved by the user is stored as the reference broadcast time zone information in step S8 of FIG. Recording reservations are made according to the broadcast time zone information. That is, a recording reservation is made in accordance with at least the second and subsequent broadcast time zone information of program A. Therefore, it is possible to prevent a program that is different from the program reserved by the user from being erroneously recorded, and thus it is possible to prevent the recording capacity of the storage unit 14 from being wasted.

  In the first embodiment of the present invention described above, the next broadcast time zone information of the broadcast time for which the user has instructed recording reservation is used as the reference broadcast time zone information in the next program search process. . For example, the broadcast time zone information for the next week of program A is used as the reference broadcast time zone information. The reference broadcast time zone information used in the next program search process is not limited to this, and the broadcast time zone from the next time after the next broadcast time when the user instructed the recording reservation, for example, the next week or later. Information may be used. In this case, the reference broadcast time zone information stored in the reservation information storage unit 18 is updated from time to time after the next time of the broadcast time when the user has instructed recording reservation, for example, with the broadcast time zone information after the next week. You should do it.

  In the present embodiment, when the next broadcast of program A is detected, the broadcast time zone information of the next broadcast of program A is stored in the reservation information storage unit 18 as the reference broadcast time zone information. It is used in the next program search process. For example, the present broadcast time zone information is compared with the next broadcast time zone information, and the broadcast time zone information having a shorter broadcast time is stored in the reservation information storage unit 18. May be used. Specifically, this week's broadcast time zone information and next week's broadcast time zone information are compared, and the broadcast time zone information of the week with the shorter broadcast time is stored in the reservation information storage unit 18 for use. You may do it.

  If the program data 47 includes longer-term program information, the broadcast time zone information for the shortest broadcast time is compared by comparing the broadcast time zone information for three weeks or more in addition to this week and next week. Alternatively, the most frequently used broadcast time zone information may be used as the reference broadcast time zone.

  The broadcast time zone information of the shortest broadcast time among the broadcast time zone information of the reserved broadcast times for which the reservation is instructed in this way and the broadcast time zone information of the broadcast times after the next of the reserved broadcast times, or the most By using the broadcast time zone information that is often used as the reference broadcast time zone information, the detection accuracy of the next program in the next program search process can be improved. Therefore, it is possible to more accurately detect the next and subsequent programs.

  Further, in the present embodiment, the multiple broadcast program is a program that is repeatedly broadcast on a weekly basis, but the multiple broadcast program may be a program that is repeatedly broadcast on a daily basis. In this case, the broadcast time zone information used as the reference broadcast time zone information may be broadcast time zone information for the next broadcast of the reserved program, or broadcast time zone information for the next week broadcast on the same day of the week. It may be.

Based on whether or not the character string information is included, it is determined whether or not the broadcast time zone of the reserved broadcast times is different from the specified broadcast time zone. Then, when the specific title information is included in the program title information of the current program, the microcomputer unit 17 determines that the broadcast time zone of the reserved broadcast times is different from the specified broadcast time zone, and other than this time Broadcast time zone information of the broadcast times is stored in the reservation information storage unit 18 as reference broadcast time zone information. For example, the reference broadcast time zone information of the program A used for the next program search process is set as broadcast time zone information other than the first broadcast where the broadcast time zone is likely to be changed.

  Thereby, as described above, the broadcast program reserved recording apparatus 2 in which the detection accuracy of the next program in the next program search process is improved can be realized with a simple configuration.

  In the broadcast program reserved recording apparatus 2 according to the second embodiment of the present invention described above, the specific character string information is searched from the program title information, and a specific broadcast such as the first broadcast or specially-organized broadcast (hereinafter “ It is determined whether or not the broadcast time zone of the reserved broadcast is different from the specified broadcast time zone based on the result. Specifically, a search is performed using character string information representing a “new” character string as the specific character string information to determine whether the broadcast is a specific broadcast.

  The specific character string information used for the search when determining whether the broadcast is a specific broadcast is not limited to the character string information representing the “new” character string. The specific character string information may be a character string whose broadcast time zone is assumed to be different from the specified broadcast time zone. For example, the specific character string information may be character string information representing a character string such as “special” or “enlarged version”. Good.
