Abstract

<P>PROBLEM TO BE SOLVED: To provide a data recording device that can delete reserved information for recording a serialized program automatically according to the last of a program, and prevents the reserved information from being deleted erroneously by the mistake in the discrimination that the program is the last. <P>SOLUTION: The data recording device 10 stores the reserved information for recording the serialized program, and records the program according to the recorded reserved information. Detailed information including the program name of a program to be reserved is acquired by the stored reserved information. Based on the detailed information, it is discriminated whether the program is the last. When it is discriminated that the program is the last, it is further discriminated whether a program that will be broadcasted next time in the broadcast frame of the program is the same program as the program that has been discriminated to be the last. When it is discriminated that the program is not the same program, reserved information is deleted with the program that has been discriminated to be the last being a target to be reserved. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a data recording apparatus and a program for recording at least one of video information and audio information constituting a program.

2. Description of the Related Art Conventionally, in a recording apparatus for recording a television program or the like, for example, a continuous drama is recorded periodically corresponding to a continuous program broadcast on the same time zone and the same channel on a predetermined day of the week. There are many devices equipped with a function for generating reservation information. In this case, it is necessary for the user to manually cancel the recording reservation when the program that was to be recorded ends. With respect to such a problem, in the recording apparatus described in Patent Document 1, a program to be recorded is final based on program information acquired using an EPG (Electronic Program Guide) that is currently widely used. A technique is disclosed in which it is determined whether or not the program is the first time, and when it is determined that the program is the last time, the reservation information is erased after the program is recorded.
JP 2003-32592 A

  However, in the recording apparatus described above, it goes without saying that the reservation information is not erased if the character information is not included, but whether or not the acquired program information includes character information for identifying the last time or the like. Therefore, if the program title itself contains the characters “final”, there is a risk that it will be mistakenly determined that the program is the final episode. There is a high possibility that a misunderstanding related to the discrimination will occur. As a result, an unexpected situation may be assumed in which the next recording is not performed because the reservation information is erased even though it is not the last time.

  In view of the above problems, the present invention is capable of automatically deleting reservation information for recording a continuous program in accordance with the final program and determining that the program is the final program. It is an object of the present invention to provide a data recording apparatus and a program that are free from erroneous deletion due to erroneous recognition.

  The data recording apparatus of the present invention includes information relating to a recording channel, a recording day of the week, and a recording time zone, and reservation information storage means for storing reservation information which is information for reserving recording of a continuous program, and stored reservations Based on the program recording means for recording the program according to the information, the program detailed information acquisition means for acquiring the program detailed information including the program name, broadcast channel, broadcast date and broadcast time zone, and the acquired program detailed information, Program end determination means for determining whether or not the program is the final program, and the current recording program that is the current recording target and the next recording that is the recording target next to the current recording program based on the acquired detailed program information The same program discriminating means for discriminating whether or not the program is the same program, and the program ending discriminating means discriminating that the currently recorded program is the last program and the same program If the the time the recorded program and the next recorded program is not determined to be the same program by another means, after this recording program is recorded, characterized by comprising a reservation information deleting means for deleting the reservation information.

  According to this configuration, in addition to the case where the program is determined to be the final time based on the acquired program detailed information, the program determined to be the final time (currently recorded program) and the broadcast frame of this program Since it is further determined whether or not the next broadcasted program (next recorded program) is the same program, and the reservation information is deleted only when it is determined that the program is not the same program, the program is the last program There is no possibility that the reservation information is erroneously deleted due to misidentification related to the determination. For example, although the program is not actually the final episode, it is assumed that the program end discriminating means misidentifies that “the program ends” due to characters such as “last” included in the program name. In such a case, the same program discriminating means discriminates that the program determined to be the last program and the program to be broadcast next in the broadcast frame of this program are the same program. The reservation information is not deleted. Therefore, the certainty of the reservation information deleting process corresponding to the last program is guaranteed.

  The above data recording apparatus further comprises a recording time zone changing means for changing the recording time zone of the reservation information, the program end discriminating means discriminates that the current recorded program is the last time, and the same program discriminating means judges the current time When it is determined that the recorded program and the next recorded program are not the same program, the same program determining means further determines whether or not the next recorded program is a program related to the current recorded program, and the next recorded program is recorded this time. When it is determined that the program is related to the program, the recording time zone changing means corresponds to the broadcast time zone included in the program detailed information of the acquired next recording program and the reservation information for recording the next recording program is recorded. The recording time zone is changed, and the reservation information deleting means preferably deletes the reservation information after the next recorded program is recorded.

  According to this configuration, after the final broadcast of the program, a special program such as a compilation of the program is often broadcast in the next broadcast frame. However, in the present invention, the program determined to be the final program If it is further determined whether or not (currently recorded program) and the program to be broadcast next time (the next recorded program) in the broadcast frame of this program are related programs, Since the reservation information is deleted after the next recording program is recorded, the reservation information is automatically deleted after the recording including the special program of the program that is the recording target by the reservation information. Thus, convenience can be further improved. In addition, the special program is often broadcast in a time zone different from the broadcast time zone of the normal program, but in the present invention, since the recording time zone of the reservation information is changed corresponding to the broadcast time zone of the special program, It is possible to respond flexibly to changes in broadcast time zones. Note that the same program discriminating means determines whether or not the current recording program and the next recording program are related programs, for example, in addition to the program name of the current recording program in the program name of the next recording program, It is assumed that the determination is made based on whether or not a character string indicating a special program such as “” or “special number” is included.

  In the above data recording apparatus, when there is a plurality of reservation information, the recording time zone changing unit changes the recording time zone of any one of the plurality of reservation information, and as a result, the recording of one reservation information is performed. When at least a part of the time zone overlaps with the recording time zone of other reservation information, it is preferable to further include a time zone duplication notification means for informing that the time zone overlaps.

  According to this configuration, as a result of changing the recording time zone of the reservation information corresponding to the broadcast time of the special program, the changed recording time zone (at least a part thereof) overlaps with the recording time zone of other reservation information. Even in the event of a failure, the user can take some measures by informing that fact. In addition, it may replace with the structure which inquires a user, and the structure which memorize | stores beforehand what kind of response | compatibility as setting information may be sufficient.

  In the above data recording apparatus, it is preferable that the program detailed information further includes the number of broadcasts of the program.

  According to this configuration, it is possible to determine whether or not the program is the final program based on the number of broadcasts in addition to, for example, the program name included in the detailed program information. As a result, for example, in a program that is broadcast continuously, the possibility that the program will be the last time is low when the number of times of broadcasting is the first, so the process of determining whether the program is the last time according to the number of times of broadcasting is omitted. For example, it is possible to realize the processing efficiently.

  In the above data recording device, the program end determining means may determine whether or not the program is the final time based on the number of times of recording for each reservation information recorded according to the reservation information in addition to the detailed program information. preferable.

  According to this configuration, it is possible to determine whether or not the program ends based on the number of recordings of the program to be recorded by the reservation information in addition to, for example, the program name included in the program detailed information. For example, when the number of times of recording reaches a predetermined number, even if the program name does not include a character indicating the last time, it can be used to prevent the last time from being missed by determining the last time. .

  In the above data recording apparatus, when it is determined by the program end determining means that the current recorded program does not end and the same program determining means determines that the current recorded program and the next recorded program are not the same program, Recording information skipping means for temporarily invalidating the reservation information for recording the next recorded program after the recording has been recorded, and when the reservation information is in an invalid state, the same program discriminating means And the next recorded program to be recorded after the recording of the next recorded program is further determined whether or not it is the same program, and the current recorded program and the next recorded program are determined to be the same program The reservation information skip means cancels the invalid state of the reservation information, and if it is determined that the program recorded this time and the program recorded one after another are not the same program, the reservation information deletion means , It is preferable to force delete the reservation information in an invalid state.

  According to this configuration, for example, another program such as a professional baseball game or a soccer game is often temporarily inserted and broadcasted in the broadcast frame of a continuous program, for example. Even if it is determined that the program is not a program, if the same program discriminating unit determines that the current recording program and the next recording program are different, the reservation information is temporarily invalidated. There is no risk of another program being broadcast being recorded in vain. Furthermore, when it is determined that the program recorded this time and the program recorded next time are the same program, the reservation information is canceled, so that the recording is automatically performed when the program to be recorded resumes. It will be resumed and it will be convenient.

  In addition, when it is determined that the program recorded this time and the program recorded next time are different, the reservation information in an invalid state is forcibly deleted, so that information indicating the program end in the program detailed information (for example, “final” Since the reservation information is deleted at this stage (the stage where the recorded program is broadcast one after another) even if the program end discriminating means cannot discriminate the end of the program, It is possible to keep the wasteful recording due to the last oversight to a minimum.

  The data recording apparatus further includes a deletion function OFF unit that turns off the forced deletion function by the reservation information deletion unit when the execution date and time of the determination by the program end determination unit and the same program determination unit is within a specific period. Is preferred.

  According to this configuration, the forced deletion function that forcibly deletes reservation information is turned off only within a specific period, so for example, the year-end and New Year period when the broadcast schedule becomes irregular is set as the specific period, and forcibly deleted during this period By turning off the function, it is possible to prevent the possibility that reservation information that does not need to be deleted is forcibly deleted.

  In the above data recording apparatus, when the program end determining means determines that the current recorded program is the last time, a deletion availability inquiry means for inquiring whether or not to delete the reservation information for recording the current recorded program. In addition, it is preferable that the reservation information deleting unit deletes the reservation information when a deletion permission instruction is given in accordance with the deletion permission / inquiry inquiry unit.

  According to this configuration, when it is determined by the program end determination means that the program is the last time, it is possible to reliably reflect the user's intention by entrusting the user's determination whether or not to delete the reservation information. It becomes possible.

  In the above data recording apparatus, the deletion availability inquiry means controls to display an inquiry screen for inquiring whether or not to delete the reservation information. The inquiry screen displays the reservation information and the program details of the acquired current recording program. It is preferable to display the information and the number of times of recording performed according to the reservation information.

  According to this configuration, the user can make a determination as to whether or not to delete the reservation information while referring to each piece of information displayed on the inquiry screen.

  In the above data recording apparatus, it is preferable that program detail information of the acquired next recorded program is further displayed on the inquiry screen.

  According to this configuration, the user can make a determination as to whether or not to delete the reservation information while referring to the program detail information of the next recorded program, so whether or not to delete the reservation information, that is, the next recording It becomes possible to easily determine whether or not a program needs to be recorded.

  The data recording apparatus preferably further includes a deletion notification unit that notifies that the reservation information is deleted by the reservation information deletion unit.

  According to this configuration, the user can surely recognize that the reservation information has been deleted.

  The program of the present invention is for causing a computer to function each means in the data recording apparatus described in any one of the above.

  By causing the computer to execute this program, it is possible to automatically delete reservation information for recording a continuous program in accordance with the last program, and to determine that the program is the last program It is possible to realize a data recording apparatus that does not have a risk of deleting reservation information by mistake due to misidentification.

  Hereinafter, a data recording apparatus and a program according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a block diagram of a data recording apparatus 10 according to an embodiment of the present invention. As shown in the figure, the data recording apparatus 10 includes a content acquisition unit 20 that acquires content from the outside, a storage unit 30 that stores various types of information, and audio information (signal) and video information (signal) included in the content. A content conversion unit 40 for converting the content, a content recording unit 50 for recording the acquired content, and a control unit 60 for performing various controls.

  When the content acquisition unit 20 receives a television broadcast such as a terrestrial wave, a BS, and a CS from the receiving antenna 81, a so-called tuner is a main component. In addition, when acquiring content from the external device 82 (a television having an external output terminal, a personal computer, various tuners, etc.), the external input terminal is a main component. Although not particularly illustrated, the content acquisition unit 20 can also acquire video / music data distributed via a communication network such as the Internet as content. In this case, the Internet connection portion is a main component. Become. Note that “content” includes video information and audio information (such as a television program), video information only (such as a silent movie), and audio information only (such as music and radio programs). It means a program composed of either.

  The content acquisition unit 20 further includes a program detailed information acquisition unit 21. The program detailed information acquisition unit 21 is a daily broadcast schedule, and shows the program name, broadcast channel, broadcast date, and broadcast of each broadcast program. Detailed program information 120 including each piece of time zone information is acquired. In this embodiment, it is assumed that the program detailed information acquisition unit 21 can acquire the program detailed information 120 for a plurality of days at a time. Further, as the detailed program information 120, for example, EPG data (electronic program guide table) can be cited.

  The storage unit 30 includes a program detailed information storage unit 31 that stores the program detailed information 120 acquired by the content acquisition unit 20 (program detailed information acquisition unit 21), and daily or weekly like a continuous drama, animation, or news program. A reservation information storage unit 32 for storing reservation information 130 (see FIG. 2) for reserving recording of a continuous program broadcasted at a fixed time zone on a fixed day of the week by the content recording unit 50; Yes. The storage unit 30 can be composed of a hard disk, various semiconductor memories, various optical disks, etc., and the type thereof is not limited.

  The content conversion unit 40 decodes or encodes video information (signal) and audio information (signal) included in the acquired content.

  The content recording unit 50 records the acquired content according to the reservation information 130 in the reservation information storage unit 32. When the content recording destination is an optical disk or the like, the content recording unit 50 has a drive as a main component. When the content recording destination is a hard disk or the like, the control unit 60 functions as the content recording unit 50.

  The control unit 60 performs various controls by supervising each unit of the data recording apparatus 10 in which, for example, a CPU is a main component. Specifically, the control unit 60 is based on the program detailed information 120 stored in the storage unit 30. A determination unit 61 that performs various determinations, a reservation information operation unit 64 that operates reservation information 130 stored in the storage unit 30, and a notification control unit 69 that performs various inquiries and notifications using the display device 91, for example. It is equipped with.

  The discriminating unit 61 further includes a program end discriminating unit 62 and an identical program discriminating unit 63, and the program end discriminating unit 62 is to be discriminated based on the detailed program information 120 stored in the storage unit 30. It is determined whether or not the program is the last episode. The same program discriminating unit 63 discriminates whether or not two programs are the same program based on each program detailed information 120.

  In particular, the same program discriminating unit 63 includes a current recording program (see FIG. 2 (b)) in which the broadcast date and time are closest to the current date and time in the continuous program that is reserved by the reservation information 130 in the storage unit 30, and the current recorded program. It is determined whether or not the next recording program (see FIG. 2B) to be recorded after recording is the same program, and becomes the recording target after recording the current recording program and the next recording program. It is determined whether or not the program recorded one after another (see FIG. 2B) is the same program (details will be described later).

  The same program discriminating unit 63 discriminates whether or not two programs are related programs based on the respective program detailed information 120. In particular, it is determined whether or not the above-mentioned current recording program and the next recording program are related programs (details will be described later). The “related program” means a program in which two program contents are not exactly the same, but one program content is related to the other program content.

  Note that the timing of determination by the program end determination unit 62 is arbitrary from the acquisition of the program detail information 120 of the currently recorded program to the broadcast start time of the next recorded program. Further, when determining whether or not the current recording program and the next recording program are the same (or related) programs, the detailed program information 120 of the next recording program is acquired. In the case of determining whether or not the current recorded program and the next recorded program are the same program, the program detailed information 120 of the next recorded program is displayed. Any time between the acquisition and the broadcast start time of the next recorded program is arbitrary. However, it is necessary to store the detailed program information 120 of the currently recorded program until the determination is made.

  The reservation information operation unit 64 temporarily stores the reservation information deletion unit 65 that deletes the reservation information 130 from the storage unit 30, the recording time zone change unit 66 that changes the recording time zone included in the reservation information 130, and the reservation information 130. A reservation information skip unit 67 that is invalidated, and a deletion function OFF unit 68 that turns off a forced deletion function (to be described later) of the reservation information 130 by the reservation information deletion unit 65.

  The reservation information deletion unit 65 determines that the current recording program whose broadcast date and time is closest to the current date and time in the continuous program that is reserved for the reservation information 130 is determined to be “final” by the program end determination unit 62, When the same program discriminating unit 63 discriminates that the currently recorded program and the next recorded program are “not the same program”, the reservation information 130 is deleted. That is, when it is determined that the current recording program is the last program, the reservation information 130 is deleted because it is not necessary to record the next time.

  Further, even if the program end determination unit 62 determines that the current recording program is “not the last time”, the reservation information deletion unit 65 and the above-mentioned next recording program (next to the current recording program) When the same program discriminating unit 63 discriminates that “the program to be recorded next” is “not the same program”, the reservation information 130 is forcibly deleted (forced deletion function). This is because the program end discriminating unit 62 may discriminate the program that is actually the last time as “not the last time”, so if the same program is not broadcast twice in succession, The reservation information 130 is deleted as an oversight.

  When the same program discriminating unit 63 discriminates that the current recording program and the next recording program are “related programs”, the recording time zone changing unit 66 uses the recording time zone of the reservation information 130 to broadcast the next recording program. Change according to the time zone. In the reservation information skip unit 67, the program end determination unit 62 determines that the current recording program is “not the last time”, and the same program determination unit 63 determines that the current recording program and the next recording program are “not the same program”. If it is determined, after the recorded program is recorded this time, the reservation information 130 for which the next recorded program is to be reserved is temporarily invalidated. In other words, the recording of the next recorded program according to the reservation information 130 is skipped.

  The deletion function OFF unit 68 turns off the forced deletion function of the reservation information 130 by the reservation information deletion unit 65 described above when the execution date and time of determination by the program end determination unit 62 and the same program determination unit 63 is within a specific period. To do. This is because, for example, the broadcast schedule becomes irregular during a specific period such as the year-end and New Year holidays, so that the reservation information 130 for recording a continuous program that has not reached the final episode is not accidentally deleted. For the setting related to the “specific period”, for example, setting information in which the year-end and New Year period is set as the specific period is stored in advance in the data recording apparatus 10 so that the user can freely change the setting information.

  The notification control unit 69 further includes a deletion notification unit 70 and a recording time zone duplication notification unit 71, and the deletion notification unit 70 stores the reservation information 130 when the reservation information 130 is deleted by the reservation information deletion unit 65. Control for notifying that it has been deleted is performed. In addition, the recording time zone duplication notifying unit 71 causes at least a part of the changed recording time zone to overlap with the recording time zone of the other reservation information 130 due to the recording time zone change of the reservation information 130 by the recording time zone changing unit 66. In such a case, control is performed to notify that effect. In addition, the recording time zone overlap notification unit 71 performs an instruction regarding the further recording time zone change of the next recorded program or the necessity of recording of the next recorded program by performing the overlap notification control of the recording time zone, for example, the input device 92 ( For example, it is acquired via a controller that communicates with the data recording apparatus 10 via infrared rays. In addition, as a specific example of the notification control by each unit of the notification control unit 69, it is assumed that the display device 91 is controlled to display a message screen.

  Next, the reservation information 130 will be specifically described with reference to FIG. As described above, the reservation information 130 is information for reserving recording of a continuous program to be recorded by the content recording unit 41 every day or every day of the week at a fixed time zone. , Information about days of the week, and time zones. For example, in the case of the reservation information A shown in FIG. 9A, a continuous program broadcast from 9 pm to 9:54 pm every Monday is recorded on the broadcast channel “8”. On the broadcast channel “4”, a continuous program broadcast every Monday to Friday from 12:00 pm to 1:54 pm is recorded. In the case of the reservation information C, a continuous program broadcast every day from 6 am to 6:50 am is recorded on the broadcast channel “1”.

  Also, as shown in FIG. 5B, when the current date and time is Friday, August 18th, 6:00 pm, in the example of the reservation information A, the current recorded program is August 21 on the broadcast channel “8”. The program will be broadcast from 9 pm to 9:54 pm on the day, and the next recorded program will be broadcast from 9 pm on August 28 to 9:54 pm on the same channel. Further, the recorded program will be a program broadcast from 9 pm on September 4 to 9:54 pm on the same channel.

  Next, a determination method by the program end determination unit 62 will be described with reference to FIG. FIG. 3 shows the detailed program information 120 of four programs broadcast in the broadcast frame from 9 pm to 10 pm on Monday, August 21, for example. As described above, the program end determination unit 62 determines whether or not the program is the last time based on the acquired program detailed information 120. More specifically, the program end determination unit 62 includes the acquired program detailed information 120. Whether or not the program is the last episode is determined based on whether or not the program name includes characters representing the last episode such as “(End)”, “End”, “End”, and “Last episode”. .

  For example, the program name of the broadcast channel “1” shown in the figure is “news 21 [final time]”, and the program name includes a character representing the last time. Is determined to be “the last time”. Similarly, the program name of the broadcast channel “8” shown in the figure is “Toyuki (End)”, and the program name includes a character representing the last episode. Is determined to be “the last time”. On the other hand, since the program name of the broadcast channel “12” shown in the figure is “Yukiyukiyuki” and the program name does not include the character representing the last episode, the program end determination unit 62 determines that the program is “final”. It is determined that it is not times.

  In addition, the program name of the broadcast channel “4” shown in the figure is “the tragedy of the last episode”, and the program name includes a character representing the last episode. It is determined that it is times. That is, in this example, there is a possibility that the program end determining unit 62 determines that the program is “the last time” even though the program is not actually the last time. On the other hand, even if the program is the last time, if the program name does not include the character representing the last time, the program end determining unit 62 determines that the program is “not the last time”. .

  Further, a determination method by the same program determination unit 63 will be described. FIG. 4A shows the current date and time of August 21 at 12:00 pm in the reservation information 130 including the recording channel “12”, the recording day “Monday”, and the recording time period “9:00 pm to 9:54 pm”. The program details information 120 of the current recording program, the next recording program, and the next recording program is shown (in addition, it is practical to acquire the program detail information 120 for the September 4 broadcast as of August 21) It is not available here for convenience of explanation). FIG. 4B shows the current date and time of August 21, 12 p.m. in the reservation information 130 for the recording channel “8”, the recording day “Monday”, and the recording time zone “9 pm to 9:54 pm”. The detailed program information 120 of the current recording program at the time, the next recording program, and the subsequent recording program is shown.

  As described above, the same program determination unit 63 determines whether or not two programs are the same or related based on the acquired program detailed information 120. More specifically, Based on whether the program names included in the acquired program detailed information 120 are the same or not, it is determined whether or not they are the same program. In the two programs, one program name is added to the other program name. ”,“ Special ”,“ summary ”,“ digest ”, etc., it is determined whether or not it is a related program depending on whether or not it includes characters indicating that it is a related program.

  For example, in the example shown in FIG. 4A, the program name of the next recorded program is “Soccer Japan VS Korea” and the program name is not the same as the program name “Yukiyukiyuki” of the currently recorded program. The program discriminating unit 63 discriminates that the current recording program and the next recording program are “not the same program”. In addition, since the program name of the current recording program and the subsequent recording program are the same as “Yukiyukiyuki”, the same program discriminating unit 63 determines that the current recording program and the subsequent recording program are “the same program”. Is determined.

  In the example shown in FIG. 5B, the program name of the next recorded program is “Toyuki omnibus” for the program name “Toyuki (end)” of the currently recorded program, and the program name of the next recorded program is Since the characters indicating that the program is a related program called “summary” is included in addition to the program name of the current recording program, the same program discriminating unit 63 determines that the current recording program and the next recording program are “ It is determined that the program is related. In addition, the program name of the recorded program is “newswoman” and the program name is not the same as the program name of the recorded program “Toyuki (End)” in the recorded program this time and the recorded program one after another. The same program discriminating unit 63 discriminates that the currently recorded program and the program recorded one after another are “not the same program”.

  Strictly speaking, although the program names are not the same in “Toyuki” and “Toyuki (End)”, the data recording device 10 uses the character “(End)” as the last time. The same program discriminating unit 63 can discriminate “Toyuki” and “Toyuki (end)” as “identical”. For the same reason, “Toyuki (the end)” and “Toyuki omnibus” are identified as “related”.

  Here, an overall flow of each process performed by each unit of the data recording apparatus 10 described above will be described with reference to flowcharts shown in FIGS. First, the program end determination unit 62 determines whether or not the currently recorded program is the last time in response to the acquisition of the program detailed information 120 of the currently recorded program (S01). If it is determined that “the last time” (S01; Yes), the end flag is turned ON (S02). If it is determined that it is not the final time (S01; No), nothing is done.

  Next, the same program discriminating unit 63 discriminates whether or not the current recording program and the next recording program are the same program according to the acquisition of the program detailed information 120 of the next recording program (S03). If it is determined that the programs are not the same program (S03; No), the program flag is turned ON (S04). If it is determined that the programs are the same program (S03; Yes), the process ends here (see FIG. 6).

  Subsequently, the control unit 40 of the data recording device 10 confirms the status of the flag (S05), and when both the end flag and the program flag are ON, the same program determination unit 63 further determines that the current recorded program and the next time It is determined whether or not the recorded program is a related program (S06). As a result of the determination, if the current recording program and the next recording program are not related programs (S06; No), the reservation information deleting unit 65 deletes the reservation information 130 after the current recording program is recorded (S07; FIG. 6).

  On the other hand, as a result of determining whether or not the current recording program and the next recording program are related, if the current recording program and the next recording program are related (S06; Yes), as shown in FIG. Moreover, the recording time zone changing unit 66 changes the recording time zone of the reservation information 130 in accordance with the broadcast time zone of the next recorded program (S08). As a result of changing the recording time zone, when at least a part of the changed recording time zone overlaps with the recording time zone of the other reservation information 130 (S09; Yes), the recording time zone duplication notification unit 71 Control to notify that effect is performed (S10). If the changed recording time zone does not overlap with the recording time zone of the other reservation information 130 (S09; No), the reservation information deletion unit 65 deletes the reservation information 130 after the next recording program is recorded. (S11).

  When the recording time zone overlap notification unit 71 notifies that the recording time zone is overlapped, as a result of obtaining an instruction to record the next recording program (S12; Yes), the next recording program is recorded. After that, the reservation information deleting unit 65 deletes the reservation information 130 (S11). If an instruction to not record the next recorded program is acquired (S12; No), after the current recorded program is recorded, the reservation information deleting unit 65 deletes the reservation information 130 (S07).

  On the other hand, in the confirmation of the flag status (S05; see FIG. 5), when only the program flag is ON, the reservation information skip unit 67 temporarily disables the reservation information 130 after the currently recorded program is recorded. (S13). Then, in response to the acquisition of the detailed program information 120 of the program recorded one time after another, the same program determination unit 63 determines whether or not the program recorded this time and the program recorded next time are the same program (S14). If it is determined that the current recorded program and the next-recorded program are “the same program” (S14; Yes), the reservation information skip unit 67 cancels the invalid state of the reservation information 130 (S15). That is, the program recording according to the reservation information 130 is resumed from the recorded program broadcast one after another.

  When it is determined that the current recorded program and the next recorded program are not “the same program” (S14; No), the reservation information deleting unit 65 deletes the reservation information 130 before the next recorded program broadcast (forced). Delete function) (S16). However, in this case, when the determination date / time falls within a specific period (year-end / New Year / etc.), The forced deletion function is turned off by the deletion function OFF unit 68 and the reservation information 130 is not deleted. Although not shown, in response to deletion of the reservation information 130 (corresponding to S07, S11, S16), the deletion notification unit 70 performs control to notify that the reservation information 130 has been deleted.

  If the program detailed information 120 includes the number of broadcasts of the program, the program end determination unit 62 may make a determination based on this information. In this case, for example, when the number of times of broadcasting is one, the number of times of broadcasting reaches a predetermined number even when it is determined that it is not the last time unconditionally or when the program name does not include characters indicating the last time. In some cases, it is assumed that it is the final round. Further, the number of times of recording for each reservation information 130 may be referred to instead of the number of times of broadcasting. Furthermore, a determination method may be used such that when the date and time of determination corresponds to a specific period and the number of broadcasts reaches a predetermined number, it is determined that it is the final time. Thereby, it is possible to further improve the accuracy related to the determination as to whether or not the program is the final episode.

  In addition, when there are a plurality of broadcast frames that can be recorded simultaneously (when multiple channels can be recorded simultaneously), as soon as the number of reservation information 130 with overlapping recording time zones exceeds the number of simultaneously recordable broadcast frames. The configuration may be such that notification (corresponding to S10) is performed under the control of the recording time zone overlap notification unit 71. Further, instead of the notification control by the recording time zone overlap notification unit 71, when the recording time zone of the reservation information 130 is overlapped (corresponding to S09; Yes), priority is given to the recording of the next recording program or the other reservation information 130 is recorded. A configuration may be used in which setting information regarding whether to give priority to the recording according to the setting is stored, and processing according to the setting information is performed.

  Further, instead of the configuration in which the reservation information 130 is deleted after the recording of the next recorded program (corresponding to S11), the reservation information 130 is deleted before the recording of the next recorded program and the recording of only the next recorded program is reserved. It may be generated. In addition, since there is a possibility that a program related to the current recorded program will be broadcast continuously, whether or not the next recorded program and the next recorded program are related programs before the reservation information 130 is deleted (or the same). It is even better to delete the reservation information 130 only when it is determined that the next recorded program and the next recorded program are “not related programs (or not the same program)”. .

  Further, in response to the determination that “the current recording program is the last time”, the recording time zone changing unit 66 responds to the change of the broadcasting time zone associated with the last broadcasting of the program, The recording time zone of the reservation information 130 may be changed according to the zone. Further, since the special program may be broadcast before the final program reaches the final time, the program end determination unit 62 determines that “the current recording program is not the final time” and the same program in order to cope with this. When the determination unit 63 determines that the current recording program and the next recording program are not the same program (only the program flag is ON in S05), the current recording program and the next recording program are related programs. The recording time zone changing unit 66 changes the recording time zone of the reservation information 130 in accordance with the broadcast time zone of the next recorded program when it is discriminated whether or not it is “related program”. But you can.

  Furthermore, a specific example of notification control by the recording time zone overlap notification unit 71 will be described. FIG. 7 shows an example of the overlap notification screen D1 that is displayed on the display device 91 under the control of the recording time zone overlap notification unit 71. As shown in the figure, in the overlap notification screen D1, in addition to the recording channel 101, the recording date 102, and the recording time zone 103 of each reservation information 130 in which at least some of the recording time zones overlap each other, the acquired program detailed information Based on 120, the program name 104 of the corresponding broadcast frame is displayed.

  Further, on the overlap notification screen D1, the user can select any reservation information 130 and change the recording time zone or delete the reservation information 130 by using the input device 92 ( In the figure, the reservation information A is selected). Therefore, the user can adjust the recording time zone so that the recording time zones of the respective reservation information 130 do not overlap or delete the unnecessary reservation information 130.

  Note that the reservation information B shown in the figure is reservation information 130 for periodically recording the continuous program “ABC news”, and when it is instructed to delete the reservation information B, the recording time zone is reserved. The user is further inquired about whether to cancel the recording of the broadcast date “August 28”, which overlaps with the information A, or to cancel the periodic recording of the continuous program “ABC News”. It is advisable to take action according to the acquired instruction.

  As described above, according to the data recording apparatus 10 according to the first embodiment described above, in addition to the case where it is determined that the program ends based on the acquired program detailed information 120, the program determined that the program ends. It is further determined whether or not the (currently recorded program) and the next broadcasted program (next recorded program) in the broadcast frame of this program are the same program, and only when it is determined that they are not the same program Since the reservation information 130 is deleted, there is no possibility that the reservation information is erroneously deleted due to a misconception related to the determination that the program is the final program.

  Note that the reservation information 130 deletion function by the reservation information deletion unit 65, the recording time zone change of the reservation information 130 by the recording time zone change unit 66, and the reservation information invalidation function by the reservation information skip unit 67 are ON. A means for switching between / OFF may be further provided. As a result, when the user desires to manually delete or change all the reservation information 130, this request can be met.

  Next, the data recording apparatus 10 according to the second embodiment of the present invention will be described. The data recording apparatus 10 according to the second embodiment executes control for inquiring whether or not to delete the reservation information 130 when the program end determining unit 62 determines that the current recorded program is the last time. That is, whether or not to delete the reservation information 130 is left to the user's judgment.

  The data recording apparatus 10 according to the second embodiment includes a deletion availability inquiry unit (not shown) in the notification control unit 69 (see FIG. 1). When the program end determination unit 62 determines that the currently recorded program is the last time, the deletion permission / inquiry inquiry unit executes control for inquiring whether or not to delete the reservation information 130.

  FIG. 8 shows an example of the deletion availability inquiry screen D2 displayed on the display device 91 under the control of the deletion availability inquiry section. As shown in the figure, the overlap notification screen D1 is a common broadcast frame that displays the current date and time display unit 111 that displays the current date and time, and the program detailed information 120 of each program that is broadcast in the broadcast frame that is the same as or close to the currently recorded program. Program display unit 112, current recording program display unit 113 for displaying program detailed information 120 of the current recording program, reservation information display unit 114 for displaying details of reservation information 130 for which the current recording program is reserved, program of the next recording program A message for displaying the next recorded program display unit 115 for displaying the detailed information 120, an operation method for instructing deletion of the reservation information 130, or an operation method for closing the deletion availability inquiry screen D2 without deleting the reservation information. The display unit 116 is configured.

  Then, the user refers to the deletion availability inquiry screen D2 and operates the input device 92 to give an instruction regarding whether or not to delete the reservation information 130, thereby recording an instruction that surely reflects his intention. This can be performed on the apparatus 10, in other words, the data recording apparatus 10 can execute a response that reliably reflects the user's intention. Further, as shown in the figure, the reservation information display unit 114 displays the number of times of recording for each reservation information 130. Therefore, the user can determine whether or not to delete the reservation information 130 while further referring to the displayed number of recordings. Further, when the program detailed information 120 includes the number of broadcasts of the program, the number of broadcasts may be further displayed in the currently recorded program display unit 113.

  In addition, when displaying this deletion possibility inquiry screen D2 before acquiring the detailed program information 120 of the next recorded program, the display of the detailed program information 120 of the next recorded program (next recorded program display unit 115) is omitted. May be. In this case, the user can hold an instruction regarding whether or not to delete the reservation information 130. If the instruction is held, the program detailed information 120 of the next recorded program is acquired, and then it can be deleted again. The inquiry screen D2 may be displayed. In addition, when there are a plurality of reservation information 130 for which it is determined by the program end determination unit 62 that the currently recorded program is the last program, each reservation information 130 is displayed as a list, and the user deletes each reservation information 130. It suffices to be able to give instructions regarding whether or not to do so. In this case, for example, on the screen that displays a list of the reservation information 130 that has been determined that the current recorded program is the last time, the user selects any one of the reservation information 130, thereby deleting the selected reservation information 130. It may be configured to display the availability inquiry screen D2.

  As described above, according to the data recording apparatus 10 according to the second embodiment, when the program end determination unit 62 determines that the program is the last time, the user's determination as to whether or not to delete the reservation information 130 is performed. By entrusting to the above, it is possible to perform a response that reliably reflects the user's intention. Further, using the above-described deletion permission / inquiry inquiry screen D2, instructions regarding the recording time zone change of the reservation information 130 by the recording time zone changing unit 66 and the temporary invalidation of the reservation information 130 by the reservation information skip unit 67 are given. Furthermore, the structure which acquires may be sufficient.
