Japanese Patent Application Laid-Open No. 2006-80803

In a conventional recording device, even if a person specified by a user actually appears in a program as a performer, if the program is not listed as a performer in the electronic program guide, the program is reserved for recording. can't do

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a recording apparatus capable of recording a program in which a person specified by a user appears even if the person is not listed as a performer in an electronic program guide. do.

In order to achieve the above object, a recording apparatus according to an aspect of the present invention includes an extraction unit for extracting program content information related to content of a program from the program, and a program whose program content information is extracted by the extraction unit. a storage unit for storing a database in which program specifying information for specifying the program and program content information extracted from the program by the extracting unit are associated with each other; and input of person specifying information for specifying a person, for each of an input unit for receiving; an estimation unit for estimating, using the database, an appearance program in which a first person specified by the person identification information received by the input unit appears; and an appearance program estimated by the estimation unit. and a recording unit that reserves and records the .

According to the recording apparatus having the above configuration, even if the person specified by the user is not listed as a performer in the electronic program guide, the program in which the person appears can be reserved for recording.

For example, the extraction unit performs the extraction by including performer identification information for identifying performers of a program to be extracted in program content information to be extracted, and the estimation unit extracts the program identification information included in the database. program identification information associated with the first performer identification information that identifies the first person as a performer is extracted from the above, and the program identified by the extracted program identification information and the program name A program that at least partially matches may be estimated as the appearance program.

As a result, a program in which a person specified by the user has appeared and a program whose program name at least partially matches can be reserved and recorded as a program in which the person appears.

For example, the extracting unit performs the extraction by including, in the program content information to be extracted, attribute information indicating the attributes of the performer specified by the performer specifying information, which is associated with each of the performer specifying information. The estimating unit limits the program specifying information, from the extracted program specifying information, to program specifying information in which an attribute indicated by attribute information associated with the first performer specifying information satisfies a predetermined condition, and performs the estimation. may be performed.

As a result, a program in which a person specified by the user has appeared as a performer (for example, a guest) with a specific attribute is excluded, and at least a part of the program name matches the program in which the person has appeared. It is possible to reserve and record a program to be performed as a program in which the person appears.

For example, the estimating unit specifies, from among the extracted program specifying information, a program that satisfies a predetermined condition in terms of the number of times the first person appeared in a program whose program name at least partially matches. The estimation may be performed by limiting to

As a result, the person specified by the user excludes programs in which at least a part of the program name matches, in which the person specified by the user has appeared less than a predetermined number of times, and in which the person has appeared less than a predetermined percentage. A program that has at least a part of the name of a program that has appeared in the past can be reserved for recording as a program in which the person appears.

For example, the extraction unit performs the extraction by including performer identification information for identifying performers of a program to be extracted in program content information to be extracted, and the estimation unit identifies performers included in the database. Performer identification information for identifying co-stars who co-starred in the program in which the first person appeared is extracted from the information, and the program in which the performer identified by the extracted performer identification information appears. It may be estimated as an appearance program.

As a result, a program in which a co-star, who co-starred in a program in which a person specified by the user has appeared, can be reserved for recording as a program in which the person appears.

For example, the estimation unit limits the extracted performer identification information to performer identification information that identifies co-stars whose number of co-stars in a program in which the first person appeared satisfies a predetermined condition. , the estimation may be performed.

As a result, co-stars who have co-starred less than a predetermined number of times and who have co-starred less than a predetermined percentage in programs in which the person specified by the user has appeared are excluded. A program in which a person appears can be reserved for recording as a program in which that person appears.

For example, the extraction unit may include, in the program content information to be extracted, performer identification information for identifying the performers of the program to be extracted, and director identification information for identifying the director or screenwriter involved in the program to be extracted. and the estimating unit extracts, from among the director-identifying information contained in the database, the director-identifying information that identifies the director or screenwriter involved in the program in which the first person appeared. , a program in which the director or screenwriter identified by the extracted director identification information is involved may be estimated as the appearance program.

As a result, it is possible to reserve and record a program in which a person specified by the user has participated in a program in which the director or screenwriter has participated.

For example, the estimation unit limits the extracted director identification information to the director identification information that identifies a director or scriptwriter who satisfies a predetermined condition in terms of the number of times the first person was involved in a program in which the first person appeared. , the estimation may be performed.

As a result, directors or screenwriters who have been involved in programs in which the person specified by the user has appeared, and who have been involved in the program a predetermined number of times or less, and who have been involved in a predetermined ratio or less. By excluding the family co-star, a program directed by the director or screenwriter can be reserved for recording as a program in which the person appears.

For example, the extraction unit includes, in the program content information to be extracted, performer identification information for identifying the performers of the program to be extracted, and program name in conversation for identifying the program name included in the conversation in the program to be extracted. The estimating unit selects programs included in conversations in programs in which the first person appeared, from among the in-conversation program name identification information included in the database. In-conversation program name specifying information for specifying a first name may be extracted, and a program having a program name specified by the extracted in-conversation program name specifying information may be estimated as the appearance program.

As a result, a program with a program name that appears in a conversation in a program in which a person specified by the user has appeared can be reserved and recorded as a program in which the person appears.

For example, the extraction unit performs the extraction by including, in the program content information to be extracted, performer identification information for identifying the performer of the program to be extracted and a keyword corresponding to the program to be extracted, The estimating unit extracts a keyword corresponding to a program in which the first person has appeared from the performer identification information included in the database, and estimates the program corresponding to the extracted keyword as the appearing program. may be

As a result, a program whose keyword is the keyword of a program in which a person specified by the user has appeared can be reserved for recording as a program in which that person appears.

For example, the estimation unit may perform the estimation by limiting the number of keywords corresponding to the program in which the first person appeared among the extracted keywords to keywords satisfying a predetermined condition. good.

As a result, keywords of programs in which a person specified by the user has appeared, excluding keywords appearing only a predetermined number of times or less, are reserved as programs in which the person appears. can be recorded.

For example, the extracting unit may extract the program content information from a character string included in the end credits of the program to be extracted.

Accordingly, it is possible to schedule recording of a program in which a person specified by the user appears, based on the content of a program that has been recorded in the past or a program that is currently being broadcast.

The present invention can be realized not only as a recording device having such a characteristic processing unit, but also as a recording method having steps of processing executed by a characteristic processing unit included in the recording device. be able to. It can also be implemented as a program for causing a computer to function as a characteristic processing unit included in the recording device or as a program for causing the computer to execute characteristic steps included in the recording method. It goes without saying that such a program can be distributed via a computer-readable non-temporary recording medium such as a CD-ROM (Compact Disc-Read Only Memory) or a communication network such as the Internet. .

According to the present invention, it is possible to provide a recording apparatus capable of reserved recording of a program in which a person specified by a user is not listed as a performer in an electronic program guide, but that person appears.

[Operation of recording device]
As described above, in the recording device 1 configured as described above, the estimation unit 40 performs the first estimation process to estimate the appearance program.

Details of the first estimation process performed by the estimation unit 40 will be described below with reference to the drawings.

FIG. 4 is a flowchart of the first estimation process.

The first estimation process is started when the input unit 30 receives input of person identification information for identifying a person.

When the first estimating process is started, the estimating unit 40 searches the database stored by the storage unit 20, and specifies the person using the person specifying information received by the input unit 30 from the program specifying information contained in the database. Program identification information associated with performer identification information (hereinafter also referred to as "first performer identification information") that identifies a person (hereinafter also referred to as "first person") as a performer. is extracted (step S110). That is, the estimation unit 40 extracts programs in which the first person has appeared in the past (hereinafter referred to as "past appearance programs") from the database.

Next, the estimating unit 40 selects one unselected program specifying information from the extracted program specifying information (step S120). Here, the unselected program specifying information refers to program specifying information that has not been selected in the past step S120 in the loop process formed by the process of step S120 to the process of step S160 (Yes) (described later). means information.

Then, the estimating unit 40 checks whether the attribute indicated by the attribute information associated with the first performer specifying information is a guest for the selected program specifying information (step S130). That is, the estimation unit 40 checks whether or not the selected past appearance program is a program in which the first person has appeared as a guest.

In the process of step S130, if the attribute is not a guest (step S130: No), the estimation unit 40 determines that the number of appearances in a program whose name at least partially matches the program specified by the selected program specifying information is It is checked whether or not the number of appearances is equal to or greater than a predetermined number of times, or whether the appearance rate is equal to or greater than a predetermined rate (step S140). That is, the estimating unit 40 determines whether the first person has appeared more than a predetermined number of times or more than a predetermined percentage in a program whose program name at least partially matches the selected past appearance program. find out if

In the process of step S130, if the number of appearances in a program with at least part of the program name matching is a predetermined number or more, or a predetermined ratio or more (step S140: Yes), the estimation unit 40 determines that the program will be broadcast in the future. A program whose program name at least partially matches is presumed to be an appearance program in which the first person appears (step S150).

In the process of step S130, if the attribute is a guest (step S130: Yes), in the process of step S140, the number of appearances in a program with at least part of the program name that matches is not a predetermined number or more, and the number of appearances is a predetermined percentage or more If not (step S140: No), and if the process of step S150 is completed, the estimation unit 40 checks whether unselected program specifying information exists in the extracted program specifying information ( step S160). That is, the estimation unit 40 checks whether or not there is an unselected past appearance program among the extracted past appearance programs.

In the process of step S160, if there is unselected program identification information (step S160: Yes), the estimation unit 40 returns to the process of step S120 and repeats the processes after step S120.

In the process of step S160, if there is no unselected program identification information (step S160: No), the estimation unit 40 ends the first estimation process.

Note that both the processing of step S130 and the processing of step S140 are processing for improving the accuracy of estimating the appearance program in which the first person appears, and are not necessarily essential processing in the first estimation processing. Absent. Therefore, the first estimation process may be a process in which either one or both of the process of step S130 and the process of step S140 are not executed.

[Discussion]
According to the recording apparatus 1 configured as described above, a program having the same name as a program in which the first person has appeared in the past is estimated to be the appearance program in which the first person appears, based on the contents of programs recorded in the past. Programs can be scheduled for recording. Therefore, the recording apparatus 1 configured as described above can reserve and record a program in which the first person appears even if the first person is not listed as a performer in the electronic program guide.

(Embodiment 2)
Here, a recording apparatus according to Embodiment 2, which is a part of the configuration of the recording apparatus 1 according to Embodiment 1, will be described.

[Configuration of recording device]
FIG. 5 is a block diagram showing the configuration of the recording device 1A according to the second embodiment.

As shown in FIG. 5, in recording device 1A, estimating unit 40 is changed from recording device 1 according to Embodiment 1 to estimating unit 40A.

By performing the first estimation process, the estimation unit 40 according to Embodiment 1 uses the database stored in the storage unit 20 so that the person identified by the person identification information accepted by the input unit 30 appears. This is an example of a configuration for estimating an appearance program.

On the other hand, the estimating unit 40A performs the second estimating process instead of the first estimating process, thereby using the database stored in the storage unit 20 to identify the person based on the person identifying information received by the input unit 30. This is an example of a configuration for estimating an appearance program in which a person who has been identified appears.

[Operation of recording device]
Details of the second estimation process performed by the estimation unit 40A will be described below with reference to the drawings.

FIG. 6 is a flowchart of the second estimation process.

The second estimation process is started when the input unit 30 accepts input of person identification information for identifying a person.

When the second estimation process is started, the estimation unit 40A searches the database stored by the storage unit 20, and selects from the performer identification information included in the database according to the person identification information accepted by the input unit 30. Performer identification information for identifying co-stars who co-starred in the program in which the identified first person appeared is extracted (step S210). That is, the estimation unit 40A extracts, from the database, the co-stars of past appearance programs in which the first person has appeared in the past.

Next, the estimation unit 40A selects one piece of unselected performer identification information from among the extracted performer identification information (step S220). Here, the unselected performer identification information refers to performers who have not been selected in the past step S220 in the loop processing formed by the processing of step S220 to the processing of step S250 (Yes) (described later). Refers to person-identifying information.

Then, the estimating unit 40A determines that the number of times the performer specified by the performer specifying information has co-starred in a past appearance program in which the first person has appeared in the past is a predetermined number of times or more, for the selected performer specifying information. , or whether or not the ratio of co-starring is equal to or higher than a predetermined ratio (step S230). That is, the estimation unit 40A checks whether or not the selected co-star has co-starred with the first person a predetermined number of times or more, or a predetermined ratio or more.

In the process of step S230, if the number of co-stars in the past appearance program is equal to or greater than the predetermined number of times, or the co-star ratio is equal to or greater than the predetermined rate (step S230: Yes), the estimation unit 40A A program in which the performer specified by the person specifying information appears is presumed to be an appearance program in which the first person appears (step S240).

In the process of step S230, if the number of co-starring times in the past appearance program is not equal to or greater than a predetermined number of times and the co-starring rate is not equal to or greater than a predetermined rate (step S230: No), and if the process of step S240 is completed, the estimation unit 40A checks whether or not unselected performer identification information exists in the extracted performer identification information (step S250). That is, the estimation unit 40A checks whether or not there is an unselected co-star among the extracted co-stars.

In the process of step S250, if unselected performer identification information exists (step S250: Yes), the estimation unit 40A returns to the process of step S220 and repeats the processes after step S220.

In the process of step S250, when there is no unselected performer identification information (step S250: No), the estimation unit 40A ends the second estimation process.

Note that the process of step S230 is a process for improving the accuracy of estimating the appearance program in which the first person appears, and is not necessarily essential in the second estimation process. Therefore, the second estimation process may be a process that does not execute the process of step S230.

[Discussion]
According to the recording device 1A configured as described above, a program in which co-stars who have co-starred with the first person appear is assumed to be the appearance program in which the first person appears, based on the content of the program recorded in the past. , the estimated program can be scheduled for recording. Therefore, even if the first person is not listed as a performer in the electronic program guide, the recording apparatus 1A configured as described above can reserve and record the program in which the first person appears.

(Embodiment 3)
Here, a description will be given of a recording device according to a third embodiment, which is a part of the configuration of the recording device 1 according to the first embodiment.

[Configuration of recording device]
FIG. 7 is a block diagram showing the configuration of a recording device 1B according to Embodiment 3. As shown in FIG.

As shown in FIG. 7, in recording device 1B, estimating unit 40 is changed from recording device 1 according to Embodiment 1 to estimating unit 40B.

By performing the first estimation process, the estimation unit 40 according to Embodiment 1 uses the database stored in the storage unit 20 so that the person identified by the person identification information accepted by the input unit 30 appears. This is an example of a configuration for estimating an appearance program.

On the other hand, the estimating unit 40</b>B performs the third estimating process instead of the first estimating process, thereby using the database stored in the storage unit 20 to identify the person based on the person identifying information received by the input unit 30 . This is an example of a configuration for estimating an appearance program in which a person who has been identified appears.

[Operation of recording device]
Details of the third estimation process performed by the estimation unit 40B will be described below with reference to the drawings.

FIG. 8 is a flowchart of the third estimation process.

The third estimation process is started when the input unit 30 receives person identification information for identifying a person.

When the third estimation process is started, the estimation unit 40B searches the database stored by the storage unit 20, and selects from the performer identification information included in the database according to the person identification information accepted by the input unit 30. Director identification information for identifying the director or screenwriter involved in the program in which the identified first person appeared is extracted (step S310). That is, the estimating unit 40B extracts from the database the director or scriptwriter involved in the past appearance program in which the first person appeared in the past.

Next, the estimating unit 40B selects one unselected supervisor specifying information from among the extracted supervisor specifying information (step S320). Here, the unselected director identification information refers to the director identification information that has not been selected in the past step S320 in the loop processing formed by the processing of step S320 to the processing of step S350 (Yes) (described later). means information.

Then, the estimating unit 40B determines, for the selected director specifying information, that the director or scriptwriter specified by the director specifying information has been involved in a past appearance program in which the first person has appeared in the past a predetermined number of times or more. , or whether or not the ratio of participation is equal to or higher than a predetermined ratio (step S330). That is, the estimating unit 40B checks whether or not the first person has been involved in past appearance programs in which the first person has appeared in the past at least a predetermined number of times or at a predetermined rate or more with respect to the selected director or screenwriter.

In the processing of step S330, if the number of times the past appearance program has been involved is equal to or greater than the predetermined number of times, or the proportion of involvement is equal to or greater than the predetermined rate (step S330: Yes), the estimation unit 40B A program in which the director or director identified by the specific information is involved is presumed to be an appearance program in which the first person appears (step S340).

In the process of step S330, when the number of times the past appearance program has been involved is not equal to or greater than a predetermined number of times, and when the percentage of involvement is not equal to or greater than a predetermined rate (step S330: No), and when the process of step S340 is completed, the estimating unit 40B checks whether or not unselected supervisor specific information exists in the extracted supervisor specific information (step S350). That is, the estimation unit 40B checks whether or not there is an unselected director or scriptwriter among the extracted directors or scriptwriters.

In the process of step S350, if unselected director identification information exists (step S350: Yes), the estimation unit 40B returns to the process of step S320 and repeats the processes after step S320.

In the process of step S350, if there is no unselected supervisor identification information (step S350: No), the estimation section 40B ends the third estimation process.

Note that the process of step S330 is a process for improving the accuracy of estimating the appearance program in which the first person appears, and is not necessarily essential in the third estimation process. Therefore, the third estimation process may be a process that does not execute the process of step S330.

[Discussion]
According to the recording device 1B having the above configuration, the first person can reproduce a program in which a director or a scriptwriter who has been involved in a program in which the first person has appeared in the past is played based on the content of the program recorded in the past. It is possible to presume an appearance program to appear and record the presumed program by reservation. Therefore, the recording apparatus 1B having the above configuration can reserve and record a program in which the first person appears even if the first person is not listed as a performer in the electronic program guide.

As shown in FIG. 9, the recording apparatus 1C has an estimating section 40C instead of the estimating section 40 of the recording apparatus 1 according to the first embodiment.

By performing the first estimation process, the estimation unit 40 according to Embodiment 1 uses the database stored in the storage unit 20 so that the person identified by the person identification information accepted by the input unit 30 appears. This is an example of a configuration for estimating an appearance program.

On the other hand, the estimating unit 40</b>C performs the fourth estimating process instead of the first estimating process, thereby using the database stored in the storage unit 20 to identify the person based on the person identifying information received by the input unit 30 . This is an example of a configuration for estimating an appearance program in which a person who has been identified appears.

[Operation of recording device]
Details of the fourth estimation process performed by the estimation unit 40C will be described below with reference to the drawings.

FIG. 10 is a flowchart of the fourth estimation process.

The fourth estimation process is started when the input unit 30 receives person identification information for identifying a person.

When the fourth estimation process is started, the estimation unit 40C searches the database stored by the storage unit 20, and selects the person identification received by the input unit 30 from the in-conversation program name identification information included in the database. In-conversation program name identification information for identifying the program name included in the conversation in the program in which the first person identified by the information appeared is extracted (step S410). That is, the estimation unit 40C extracts, from the database, program names in conversations included in conversations of past appearance programs in which the first person has appeared in the past.

Next, the estimation unit 40C selects one unselected in-conversation program name identification information from the extracted in-conversation program name identification information (step S420). Here, the unselected in-conversation program name specifying information refers to information that has been selected in the past step S420 in the loop processing formed by the processing of step S420 to the processing of step S440 (Yes) (described later). In-conversation program name identification information that does not exist.

Then, the estimating unit 40C estimates that a program having a program name specified by the selected in-conversation program name specifying information to be broadcast from now on is an appearance program in which the first person appears (step S430).

When the process of step S430 ends, the estimation unit 40B checks whether or not unselected in-conversation program name specifying information exists in the extracted in-conversation program name specifying information (step S440). That is, the estimation unit 40C checks whether or not there is an unselected in-conversation program name among the extracted in-conversation program names.

In the process of step S440, if there is unselected in-conversation program name specifying information (step S440: Yes), the estimation unit 40C returns to the process of step S420 and repeats the processes after step S420.

In the process of step S440, when there is no unselected in-conversation program name specifying information (step S440: No), the estimation unit 40C terminates the fourth estimation process.

[Discussion]
According to the recording device 1C having the above configuration, the first person appears in the program with the name of the program in the conversation included in the conversation in the program in which the first person has appeared in the past, based on the content of the program recorded in the past. It is possible to presume that the program will appear, and schedule recording of the presumed program. Therefore, even if the first person is not listed as a performer in the electronic program guide, the recording apparatus 1C configured as described above can reserve and record the program in which the first person appears.

(Embodiment 5)
Here, a recording apparatus according to Embodiment 5, which is partly modified from the recording apparatus 1 according to Embodiment 1, will be described.

[Configuration of recording device]
FIG. 11 is a block diagram showing the configuration of a recording device 1D according to Embodiment 5. As shown in FIG.

As shown in FIG. 11, recording device 1D has estimating unit 40D instead of estimating unit 40 of recording device 1 according to the first embodiment.

By performing the first estimation process, the estimation unit 40 according to Embodiment 1 uses the database stored in the storage unit 20 so that the person identified by the person identification information accepted by the input unit 30 appears. This is an example of a configuration for estimating an appearance program.

On the other hand, the estimating unit 40</b>D performs the fifth estimating process instead of the first estimating process, thereby using the database stored in the storage unit 20 to identify the person based on the person identifying information received by the input unit 30 . This is an example of a configuration for estimating an appearance program in which a person who has been identified appears.

[Operation of recording device]
Details of the fifth estimation process performed by the estimation unit 40D will be described below with reference to the drawings.

FIG. 12 is a flowchart of the fifth estimation process.

The fifth estimation process is started when the input unit 30 receives person identification information for identifying a person.

When the fifth estimation process is started, the estimation unit 40D searches the database stored by the storage unit 20, and is identified by the person identification information received by the input unit 30 from the keywords included in the database. A keyword corresponding to the program in which the first person appeared is extracted (step S510). That is, the estimation unit 40B extracts, from the database, keywords corresponding to past appearance programs in which the first person has appeared in the past.

Next, the estimation unit 40D selects one unselected keyword from the extracted keywords (step S520). Here, the unselected keyword means a keyword that has not been selected in the past step S520 in the loop processing formed by the processing of step S520 to the processing of step S550 (Yes) (described later). say.

Then, for the selected keyword, the estimation unit 40D determines whether the number of appearances of the first person in the program specified by the program specifying information corresponding to the keyword is a predetermined number or more, or the appearance rate is a predetermined rate or more. It is checked whether or not there is (step S530). That is, the estimation unit 40D checks whether or not the first person has appeared in the program of the selected keyword more than a predetermined number of times, or more than a predetermined percentage of times.

In the process of step S530, if the number of appearances of the first person is equal to or greater than the predetermined number of times or is equal to or greater than the predetermined percentage (step S530: Yes), the estimation unit 40D selects keywords that will be broadcast in the future. The program specified by the program specifying information is presumed to be the appearance program in which the first person appears (step S540).

In the process of step S530, when the number of appearances of the first person is not equal to or greater than a predetermined number of times and is not equal to or greater than a predetermined percentage (step S530: No), and when the process of step S540 ends, the estimation unit 40D , it is checked whether or not an unselected keyword exists in the extracted keywords (step S550).

In the process of step S550, if there is an unselected keyword (step S550: Yes), the estimation unit 40D returns to the process of step S520 and repeats the processes after step S520.

In the process of step S550, if there is no unselected keyword (step S550: No), the estimation unit 40D ends the fifth estimation process.

Note that the process of step S530 is a process for improving the accuracy of estimating the appearance program in which the first person appears, and is not necessarily essential in the fifth estimation process. Therefore, the fifth estimation process may be a process that does not execute the process of step S530.

[Discussion]
According to the recording device 1D configured as described above, based on the contents of the programs recorded in the past, the program corresponding to the keyword corresponding to the program in which the first person has appeared in the past is regarded as the appearance program in which the first person has appeared. It is possible to estimate and schedule recording of the estimated program. Therefore, even if the first person is not listed as a performer in the electronic program guide, the recording apparatus 1D configured as described above can reserve and record the program in which the first person appears.
