BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the following embodiments, the same or equivalent elements are denoted by the same reference numerals in the drawings, and overlapping descriptions are omitted.

<First embodiment>
The first embodiment will be described below. FIG. 1 is a block diagram showing an example of the configuration of the recording device 10. As shown in FIG. The configuration of the recording device 10 is common to each embodiment. The configuration of the recording device 10 is not limited to the example in FIG. The recording device 10 is a recorder or the like that records a program received from a broadcasting station. The recording device 10 may be a device such as a personal computer or a mobile terminal. Also, the recording device 10 of each embodiment will be described as having a function of reproducing a recorded program. However, the recording device 10 may not have the playback function. In this case, the recording device 10 outputs the recorded program to the external playback device.

The recording device 10 receives programs from the broadcasting station server 11 . The broadcasting station server 11 is a server of a television station. A program is data of a TV program broadcast by a TV station. In the following description, it is assumed that a plurality of television stations each operate a broadcasting station server 11, and each broadcasting station server 11 distributes a program. Each broadcasting station server 11 may distribute the program via radio waves, or may distribute the program via a network such as the Internet.

A program distributed by each broadcasting station server 11 is program data including video, audio, text, and other information. The electronic program guide is hereinafter referred to as an EPG (Electronic Programming Guide).

A speaker 12 and a monitor 13 are connected to the recorder 10 . The speaker 12 is an audio output unit that outputs audio when the program recorded in the recording device 10 is reproduced. The monitor 13 is a display unit that displays an image when the program recorded in the recording device 10 is reproduced. The monitor 13 displays various information in addition to the video of the program. Either one or both of the speaker 12 and the monitor 13 may be provided outside the recording device 10 or may be provided in the recording device 10 . For example, when recording device 10 is built into a television, speaker 12 and monitor 13 correspond to the speaker and monitor of the television. The remote controller 14 is a remote controller used when the user operates the recording device 10 .

The recording device 10 includes a program acquisition unit 20, a program information storage unit 21, a reserved recording information storage unit 22, a broadcast end estimation unit 23, a reserved recording control unit 24, an operation reception unit 25, a recording control unit 26, a hard disk 27, and playback control. A unit 28 and a display control unit 29 are included. Some of the units of the recorder 10 in the example of FIG. 1 may be omitted according to each embodiment.

The functions of the program acquisition unit 20, the broadcast end estimation unit 23, the reserved recording control unit 24, the recording control unit 26, the reproduction control unit 28, and the display control unit 29 are performed by one or more processors such as a computer or a CPU (Central Processing Unit). It is realized by executing a predetermined program. The program information storage unit 21 and the reserved recording information storage unit 22 are storage areas of a part of the non-volatile memory. The hard disk 27 is a storage device for storing recorded program data, and corresponds to a recording unit. Recorded program data may be stored in a storage device such as an SSD (Solid State Drive) instead of the hard disk 27 .

The program acquisition unit 20 is an acquisition unit that acquires program data distributed by the broadcasting station server 11 . The program acquisition section 20 outputs the acquired program data to the recording control section 26 . When the EPG is included in the program data, the program acquisition section 20 acquires the EPG from the program data and stores the acquired EPG in the program information storage section 21 . EPG may be acquired separately from program data. In such a case, the program acquisition section 20 stores the acquired EPG in the program information storage section 21 .

The program information storage unit 21 stores the EPG acquired by the program acquisition unit 20 . The program information storage unit 21 stores not only the latest EPG but also an EPG from a certain period of time ago (for example, one week ago). The reserved recording information storage unit 22 stores the designated reserved recording information based on the user's operation. The user can use the remote controller 14 to schedule recording of a program. A case in which repeated scheduled recording of a regular broadcast program is set for the recorder 10 will be described below.

A regular broadcast program is a program that is broadcast in a predetermined time slot at regular intervals. For example, a regular broadcast program is a program that is broadcast in a predetermined time slot every week. The period in which the regular broadcast program is broadcast may be any period. For example, a regularly broadcast program may be a program that is broadcast at the same time every day. The time slot of the regular broadcast program is not limited to the above example. The time slot in which the regular broadcast program is broadcast may differ from the predetermined time slot. For example, when a program preceding a regular broadcast program is extended, the time slot in which the regular broadcast program is broadcast may be delayed by the extended time.

The broadcast end estimation unit 23 is an estimation unit that estimates the end of the regular broadcast program. Hereinafter, it is assumed that the regular broadcast program is broadcast for a predetermined period. For example, a regular broadcast program is broadcast for three months as one course, and ends three months after the broadcast of the regular broadcast program starts. The period during which the regular broadcast program is broadcast may be any period. A broadcast end estimating unit 23 estimates the end of the broadcast of the regularly scheduled and recorded programs based on the change in program names of a plurality of regularly scheduled and recorded programs including one or more regularly scheduled and recorded programs. . Hereinafter, a regular broadcast program that has been repeatedly reserved for recording will be referred to as a reserved regular broadcast program. Details of the processing of the broadcast end estimation unit 23 will be described later.

The reserved recording control unit 24 deletes the reserved recording information of the reserved regular broadcast program stored in the reserved recording information storage unit 22 based on the result estimated by the broadcast end estimating unit 23 . The reserved recording control unit 24 can also perform control to notify the result estimated by the broadcast end estimation unit 23 . The reserved recording control unit 24 corresponds to a reservation processing unit that executes processing related to recording reservation. Notification of the estimation result will be described in the second embodiment.

The recording control unit 26 controls recording of the program data output by the program acquisition unit 20 on the hard disk 27 . The recording control unit 26 records the program data corresponding to the reserved recording information stored in the reserved recording information storage unit 22 on the hard disk 27 . The recording control unit 26 records, on the hard disk 27, the program data that matches the broadcast station (channel), date and time zone designated by the reserved recording information. The recording control unit 26 may perform predetermined encryption on the program data to be recorded.

The reproduction control unit 28 reads program data recorded on the hard disk 27 and controls reproduction of the read program data. The playback instruction is given by the user using the remote control 14, for example. The operation accepting unit 25 accepts a reproduction instruction from the remote controller 14 . Based on the reproduction instruction received by the operation receiving section 25, the reproduction control section 28 controls reproduction of the program data for which the reproduction instruction is given. Program data to be reproduced is output to the speaker 12 and the monitor 13 . The display control unit 29 controls display of the result estimated by the broadcast end estimation unit 23 on the monitor 13 under the control of the reserved recording control unit 24 . Details will be described in a second embodiment.

FIG. 2 is a diagram showing an example of changes in program names of regular broadcast programs in the first embodiment. A dashed line in FIG. 2 indicates a regular broadcast program in a time zone for which repeated reservation recording is set. In the example of FIG. 2, a regular broadcast program (program name "Drama AAA") that is broadcast every Friday from 22:00 to 23:00 is set as repeated scheduled recording.

Repeated scheduled recording is set by the user. For example, when the user designates a desired program using the remote control 14 while the EPG is being displayed on the monitor 13, the operation receiving unit 25 receives the designation of the program. The EPG contains program information of programs broadcast by each broadcasting station. The program information includes information on the program name, day of the week, time zone and broadcasting station. The operation receiving unit 25 stores the program information of the designated program in the reserved recording information storage unit 22 as reserved recording information. Also, repeated scheduled recording may be set by directly designating the day of the week, time period, and broadcasting station. Repeated scheduled recording may be set using, for example, a terminal such as a smartphone that is linked with the recording device 10 .

In the example of FIG. 2, the program name of the regular broadcast program for which repeated scheduled recording is set is "drama AAA". In the EPG one week ago, the program name of the regularly broadcast program in the time slot of "22:00-23:00" every Friday was "Drama AAA". On the other hand, in the current EPG, the program name of the regularly broadcast program in the time slot of "22:00-23:00" every Friday is "Drama BBB". Therefore, the program name of the regular broadcast program in the time slot of "22:00-23:00" every Friday is changed. In this case, there is a possibility that the regular broadcasting program with the program name "Drama AAA" has ended.

It is assumed that the regular broadcast program in the same time slot after the regular broadcast program for which the user has repeatedly set reserved recording is a program that the user does not intend to record. In order to prevent a program not intended by the user from being recorded continuously, it is preferable to delete the setting of repeated scheduled recording in FIG.

A broadcast end estimation unit 23 estimates the end of a regular broadcast program based on a change in the program names of a plurality of regular broadcast programs including one or more reserved regular broadcast programs. In other words, the broadcast end estimating unit 23 estimates the end of the regular broadcast program based on changes in the program names of a plurality of regular broadcast programs rather than the change in the program name of one regular broadcast program. Therefore, the broadcast end estimation unit 23 can estimate the end of the regular broadcast program with high estimation accuracy.

In the example of FIG. 2, as another regular broadcast program, the program name of the regular broadcast program in the time slot of "22:00-23:00" every Saturday is changed from "drama CCC" to "drama DDD". . The other regular broadcast program may be a regular broadcast program for which repeated scheduled recording is not set, or a regular broadcast program for which repeated scheduled recording is set. Also, the other regular broadcast program may be a regular broadcast program in a different time slot from the reserved regular broadcast program.

Regular broadcast programs often end at regular intervals (for example, every three months). In addition, there are many cases in which a plurality of regular broadcast programs end at close timing (for example, the same week). A broadcast end estimating unit 23 estimates the end of a reserved regular broadcast program based on a change in the program names of a plurality of regular broadcast programs whose broadcast ends at close timing, so that the end of the regular broadcast program can be estimated with high accuracy. can be estimated.

When the broadcast end estimating unit 23 estimates that the scheduled regular broadcast program has ended, the scheduled recording control unit 24 deletes the estimated scheduled recording information of the scheduled scheduled broadcast program from the scheduled recording information storage unit 22 . As a result, it is possible to prevent a regular broadcast program in the same time slot from being recorded on the hard disk 27 after the reserved regular broadcast program ends.

In the example of FIG. 2, there is also a case where repeated scheduled recording of another regular broadcast program is set, and the program name of the other regular broadcast program has not changed between the EPG of one week ago and the current EPG. . For example, another regularly scheduled program is a program that is broadcast throughout the year. As described above, based on the EPG of one week ago and the current EPG, the broadcast end estimating unit 23 selects a regularly broadcast program (program name "Drama AAA") every Friday from 22:00 to 23:00. ) has ended. On the other hand, the above another regular broadcast program has the same program name between the EPG one week ago and the current EPG. Therefore, the broadcast end estimation unit 23 does not estimate that another regular broadcast program has ended. Also, the reserved recording control unit 24 does not delete the reserved recording information of another regular broadcast program from the reserved recording information storage unit 22 .

Next, processing of the first embodiment will be described. FIG. 3 is a flowchart showing an example of the flow of processing relating to repeated scheduled recording in the first embodiment. The processing of the flowchart of FIG. 1 is periodically executed at a predetermined timing. For example, the recording device 10 may start executing the flowchart of FIG. 1 at the timing when the EPG is updated.

The broadcast end estimation unit 23 acquires the current EPG stored in the program information storage unit 21 (step S11). A current EPG is a modern EPG. For example, if the recorder 10 is set to acquire an EPG at a predetermined time every day, the current EPG may not be the EPG at the latest time.

The program information storage unit 21 stores not only the current EPG but also the EPG of a certain period of time ago. The broadcast end estimating unit 23 acquires the EPG of a certain period ago stored in the program information storage unit 21 (step S12). The fixed period is, for example, one week.

The broadcast end estimation unit 23 acquires the program information of the reserved regular broadcast program stored in the reserved recording information storage unit 22 (step S13). The program information of the regular broadcast program acquired in step S13 includes information on the program name, the day of the week (or the day on which the program is broadcast), and the time period.

The broadcast end estimating unit 23 searches the acquired current EPG and the EPG of a certain period ago, and detects whether there is a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program (step S14).

The broadcast end estimating unit 23 determines whether the detection result of step S14 indicates that the program names of a plurality of regular broadcast programs including the reserved regular broadcast program have been changed (step S15). If there is a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program, the broadcast end estimation unit 23 determines Yes in step S15. In this case, the broadcast end estimation unit 23 estimates that the reserved regular broadcast program has ended (step S16). The broadcast end estimation unit 23 notifies the reservation recording control unit 24 of the estimation result of step S16. The reserved recording control unit 24 deletes the reserved recording information of the reserved regular broadcast program whose regular broadcast program is estimated to have finished from the reserved recording information storage unit 22 (step S17).

If the broadcast end estimating unit 23 determines No in step S15, it is not necessary to delete the reserved recording information of the reserved regular broadcast program. Therefore, when the broadcast end estimating unit 23 determines No in step S15, the process of the flowchart of FIG. 3 is ended.

As described above, in the first embodiment, based on the change in the program names of a plurality of regular broadcast programs including the regular broadcast program for which repeated scheduled recording is set, the regular broadcast program for which repeated scheduled recording is set ends. It is estimated that Based on changes in the program names of a plurality of regular broadcast programs, not the name of one regular broadcast program, it is estimated whether the regular broadcast program set for repeated reservation recording has ended, so the end of the regular broadcast program is determined. It can be estimated with high accuracy. In addition, the setting of repeated reserved recording of the regular broadcast program estimated to end is automatically deleted. This prevents continuous recording of a regular broadcast program that the user does not intend.

In the above example, based on the current EPG and the EPG of a certain period of time ago, it is detected whether or not the program names of a plurality of regular broadcast programs including a regular broadcast program set for repeated reservation recording have changed. The EPG may include not only program information for the current day, but also program information for a certain period of time ahead. For example, an EPG may contain program information from the date the EPG was acquired to the date one week ahead. In such a case, one EPG can detect whether or not the program names of a plurality of regular broadcast programs including a regular broadcast program for which repeated scheduled recording is set change. Therefore, the number of EPGs stored in the program information storage unit 21 may be one. Since the number of EPGs stored in the program information storage unit 21 is reduced, the amount of data stored in the program information storage unit 21 can be reduced.

<Second embodiment>
Next, a second embodiment will be described. In the second embodiment, the user is notified of a scheduled scheduled broadcast program that is estimated to end, and the repeated scheduled recording setting is deleted based on an instruction from the user.

FIG. 4 is a diagram showing an example of changes in program names of regular broadcast programs in the second embodiment. In the example of FIG. 4, repeated scheduled recording of two regular broadcast programs is set. The program names of the two scheduled regular broadcast programs are different between the EPG one week ago and the current EPG. Also, the program names of other regular broadcast programs for which repeated scheduled recording is not set are different between the EPG one week ago and the current EPG.

Therefore, the broadcast end estimation unit 23 estimates that the two reserved regular broadcast programs have ended. The reserved recording control unit 24 causes the monitor 13 to display, via the display control unit 29, information regarding the setting of repeated reserved recording of the two reserved regular broadcast programs whose broadcasting is estimated to have ended.

FIG. 5 is a diagram showing an example of a screen displayed on the monitor 13. As shown in FIG. Screen 30 includes broadcast end information 31A and 31B. The broadcast end information 31A and 31B is information indicating a reserved regular broadcast program whose broadcast is estimated to have ended. The number of pieces of broadcast end information varies according to the number of reserved regular broadcast programs whose broadcast is estimated to have ended by the broadcast end estimation unit 23 .

By displaying the broadcast end information 31A and 31B on the screen 30, the user can recognize that the two reserved regular broadcast programs have ended. Screen 30 includes delete execution button 32 and cancel button 33 . The user can delete the reserved recording information of the reserved regular broadcast program by performing an operation of pressing the delete execution button 32 using the remote controller 14 . The cancel button 33 is a button for terminating the process without deleting the reserved recording information.

FIG. 6 is a flow chart showing an example of the flow of processing relating to repeated scheduled recording in the second embodiment. Of the processes in the flowchart of FIG. 6, the processes from steps S11 to S16 are the same as those in the flowchart of FIG. 3, and thus description thereof is omitted.

When the broadcast end estimation unit 23 estimates that the scheduled scheduled broadcast program will end, the scheduled recording control unit 24 notifies the scheduled recording information of the estimated scheduled scheduled broadcast program (step S21). For example, the reserved recording control unit 24 displays the screen 30 of FIG. . The scheduled recording information of the scheduled regular broadcast program whose broadcast is estimated to end may be notified by voice from the speaker 12, for example.

The operation receiving unit 25 uses the remote control 14 to determine whether or not a deletion instruction has been received from the user (step S22). When receiving a deletion instruction from the user, the operation receiving unit 25 determines Yes in step S22. In this case, the operation receiving unit 25 deletes the reserved recording information for which the deletion instruction is received from the reserved recording information storage unit 22 (step S23). If the operation accepting unit 25 determines No in step S22, the process of the flowchart of FIG. 6 ends.

In the second embodiment, the user is notified of the scheduled recording information without automatically deleting the setting of repeated scheduled recording of the scheduled scheduled broadcast program whose scheduled scheduled broadcast program is estimated to end. Thereby, the user can delete the reserved recording information after confirming the reserved recording information of the reserved regular broadcast program whose broadcasting is estimated to end.

For example, when the broadcast end estimation unit 23 estimates that a plurality of reserved regular broadcast programs will end, the user can collectively delete the scheduled recording information of the notified plurality of reserved regular broadcast programs. Also, the user may be able to selectively delete some of the reserved recording information of a plurality of reserved regular broadcast programs. For example, in the example of FIG. 5, the operation receiving unit 25 may receive an operation to delete only the reserved recording information of the reserved regular broadcast program indicated by the broadcast end information 31A. In this case, the reserved recording information of the reserved regular broadcast program indicated by the broadcast end information 31A is deleted, and the reserved recording information of the reserved regular broadcast program indicated by the broadcast end information 31B is not recorded.

<Third Embodiment>
Next, a third embodiment will be described. FIG. 7 is a diagram showing an example of changes in program names of regular broadcast programs in the third embodiment. As shown in the example of FIG. 7, in the EPG of one week ago, a regular broadcast program with the program name "Drama AAA" that is broadcast every Friday in the time slot of "22:00-23:00" is repeatedly reserved for recording. is set as In addition, a regular broadcast program of "Drama CCC" is broadcast as another regular broadcast program every Saturday during the time slot of "22:00-23:00".

On the other hand, in the current EPG, the program name of the program that is broadcast every Friday from 22:00 to 23:00 is 'Special Disaster Broadcast'. Also, in the current EPG, the program name of the program that is broadcast every Saturday from 22:00 to 23:00 is 'Disaster Report Special Program'. For example, when a major disaster or the like occurs, each broadcasting station switches the program to be broadcast from a regular broadcast program to a special program that reports on the disaster.

In this case, since the program names of a plurality of regular broadcast programs including the reserved regular broadcast program have changed, the broadcast end estimating unit 23 estimates that the regular broadcast program for which repeated scheduled recording has been set has ended. However, the result estimated by the broadcast end estimating unit 23 is the result resulting from a switch to a temporary program that is temporarily broadcast, and in fact, there is a possibility that the broadcast of the reserved regular broadcast program has not ended. be.

Therefore, the broadcast end estimating unit 23 also refers to the EPG after a certain period of time (for example, one week later) to estimate whether the regular broadcast program for which repeated reservation recording is set has ended. FIG. 8 is a flowchart showing an example of the flow of processing relating to repeated scheduled recording in the third embodiment. Since each process from step S11 to step S14 is the same as the flowchart in FIG. 3, description thereof is omitted.

When the broadcast end estimating unit 23 determines that there is a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program based on the current EPG and the EPG of a certain period ago, it determines Yes in step S15. Then, the process proceeds to step S31.

The broadcast end estimation unit 23 acquires an EPG after a certain period of time (step S31). The EPG after a certain period of time is, for example, the EPG after one week. The EPG one week later can be obtained, for example, from a network service server that provides the EPG. The network service server provides, for example, an EPG containing program information from now until a certain period of time later.

The broadcast end estimating unit 23 searches for the EPG before the certain period of time stored in the program information storage unit 21 and the acquired EPG after the certain period of time (step S32). Based on the search result, the broadcast end estimation unit 23 detects whether there is a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program (step S33). In step S14, based on the results of searching the EPG of one week ago and the current EPG, it is detected whether or not there has been a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program. On the other hand, in step S33, based on the results of searching the EPG one week before and the EPG one week later, it is detected whether or not there is a change in the program names of a plurality of regular broadcast programs including one or more reserved regular broadcast programs.

As a result of the search in step S33, the broadcast end estimation unit 23 determines whether there is a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program (step S34). When the broadcast end estimating unit 23 determines that there is a change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program, it determines Yes in step S34. In this case, the broadcast end estimation unit 23 estimates that the reserved regular broadcast program has ended in step S16. Also, the reserved recording control unit 24 deletes the reserved recording information of the reserved regular broadcast program estimated in step S17.

If the broadcast end estimating unit 23 determines that there is no change in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program, it determines No in step S34. In this case, steps S16 and S17 are not executed.

That is, even if it is determined as Yes in step S15, if it is determined as No in step S34, it is not estimated that the reserved regular broadcast program has ended, and the reserved recording information of the reserved regular broadcast program is not deleted.

For example, as in the example of FIG. 7, based on the EPG of one week ago and the current EPG, even if the condition that the reserved regular broadcast program is estimated to end is met, when the EPG of one week later is also considered, It is no longer estimated when the reserved regular broadcast program ends. Therefore, even if the program information of the EPG is switched to a temporary special program for reporting a disaster, it can be estimated with high accuracy whether the reserved regular broadcast program has ended. In the above example, the example in which the third embodiment is applied to the first embodiment has been described, but the third embodiment can also be applied to the second embodiment.

In the third embodiment, an example in which the temporary program is a program reporting a disaster has been described, but the temporary program is not limited to a program reporting a disaster. For example, during a specific period such as year-end and New Year holidays, each broadcasting station simultaneously switches the programs to be broadcast from regular broadcast programs to special programs for the year-end and New Year holidays. The third embodiment can also be applied when a special program (temporary program) is broadcast during such a specific period.

<Fourth Embodiment>
Next, a fourth embodiment will be described. In the fourth embodiment, the program acquisition unit 20 stores in the program information storage unit 21 only EPGs of programs having the same attribute as the reserved recording information stored in the reserved recording information storage unit 22 .

FIG. 9 is a diagram showing an example of changes in program names of regular broadcast programs in the fourth embodiment. The EPG program information may include information (attribute information) indicating attributes of the program in addition to information such as the program name. In the example of FIG. 9, the program information of the regular broadcast programs shaded is stored in the program information storage unit 21. FIG. On the other hand, the program information of regular broadcast programs that are not hatched are not stored in the program information storage unit 21 .

In the example of FIG. 9, the attribute is the genre of the program. Also, drama, news and sports are shown in FIG. 9 as examples of program genres. Attributes may be other than the genre of the program. For example, an attribute may be a particular location, a particular season, or the like.

It is assumed that the reserved recording information storage unit 22 stores reserved recording information whose genre is drama. In this case, as shown in the example of FIG. 9, only the program information whose genre is drama among the EPGs is stored in the program information storage unit 21 . Therefore, in the example of FIG. 9, program information whose genres are news and sports is not stored in the program information storage unit 21 .

A broadcast end estimation unit 23 estimates whether a reserved regular broadcast program has ended, based on changes in the program names of a plurality of regular broadcast programs including the reserved regular broadcast program. Also, the broadcast end estimation unit 23 acquires the program information stored in the program information storage unit 21 and estimates whether the regular broadcast program has ended.

As described above, the program information storage unit 21 stores program information of programs narrowed down to the same genre as that of the reserved regular broadcast program. Regularly broadcast programs of the same genre are more likely to end sooner rather than later. Therefore, the broadcast end estimation unit 23 can estimate whether the reserved regular broadcast program has ended with higher accuracy.

Further, the program information storage unit 21 stores the program information of the programs narrowed down to the same genre as the genre of the reserved regular broadcast program among all the program information of the EPG. The number of pieces of program information stored is reduced. Therefore, the amount of data stored in the program information storage unit 21 can be reduced. The fourth embodiment described above can also be applied to the first to third embodiments.

<Fifth Embodiment>
Next, a fifth embodiment will be described. FIG. 10 is a diagram showing an example of changes in program names of regular broadcast programs in the fourth embodiment. The broadcast end estimating unit 23 estimates whether the reserved regular broadcast programs have ended, including the program names of other regular broadcast programs for which repeated reservation recording is not set.

In the fifth embodiment, when estimating the end of a reserved regular broadcast program using the program name of a regular broadcast program for which repeated reservation recording is not set, the broadcast end estimation unit 23 estimates the end of the reserved regular broadcast program at the same time as the reserved regular broadcast program. Use program names of one or more other regular programs broadcast by different stations in the band.

In the example of FIG. 10A, the reserved regular broadcast program is a regular broadcast program of broadcasting station 1 in the time slot of "22:00-23:00" every Friday, and the program names are "drama AAA" to "drama BBB." is changing to A broadcast end estimating unit 23 determines whether the program name of the regular broadcast program of the broadcasting station 2 in the same time slot as the reserved regular broadcast program, ie, 22:00-23:00 every Friday, has changed. . The name of the program in this time slot is changed from "Drama HHH" to "Drama III".

When using other regular broadcast programs for which repeated scheduled recording is not set for estimation determination, the broadcast end estimating unit 23 does not use all program information in the EPG, but finds other regular broadcast programs in the same time zone as the reserved regular broadcast programs. Program information of regular broadcast programs is used.

Therefore, the broadcast end estimating unit 23 can narrow down the number of pieces of program information used when performing the above estimation, thereby reducing the amount of processing when performing the estimation. Further, the program information storage unit 21 may store program information of other regular broadcast programs narrowed down to the same time slot as the reserved regular broadcast program. As a result, the amount of program information to be stored in the program information storage unit 21 is reduced, so that the amount of data to be stored in the program information storage unit 21 can be reduced.

FIG. 10B shows an example in which, as another regular broadcast program, program information of a regular broadcast program that is before or after a predetermined period of time from the time slot of the reserved regular broadcast program is used by the broadcast end estimation unit 23 . The example of FIG. 10B shows an example of another regular broadcast program of a different broadcasting station 2 that is shifted by one hour from the reserved regular broadcast program. The time before or after the time zone of the reserved regular broadcast program may be any time.

The program name of other regularly broadcast programs has changed from "Drama JJJ" to "Drama KKK." Since the program names of the two regular broadcast programs including the reserved regular broadcast program have changed, the broadcast end estimation unit 23 estimates that the reserved regular broadcast program has ended.

As shown in FIG. 10B, even if the program information of a regular broadcast program that is not in the same time slot as the reserved regular broadcast program but shifted forward or backward by a predetermined time is used, the broadcast end estimation unit 23 determines that the reserved regular broadcast program has ended. It is possible to estimate whether In addition, since the program information used as other regular broadcast programs is narrowed down to regular broadcast programs of a predetermined time before and after the time zone of the reserved regular broadcast program, the amount of processing when estimating can be reduced, and the program information The amount of data stored in the storage unit 21 can also be reduced. The fifth embodiment described above can also be applied to the first to fourth embodiments.

The order of processing in the flowcharts described in the above embodiments can be changed as much as possible. Further, the embodiments according to the present invention are not limited to the above-described forms, and can be modified as appropriate. Further, the features of each embodiment may be replaced with features that are substantially similar, that provide similar effects, or that serve similar purposes.
