Description

  The present invention relates to a hard disk device that records a TV program and other information on a hard disk and reproduces a TV program and other information recorded on the hard disk, and in particular, automatically deletes the information recorded on the hard disk. Related to the function.

  In recent years, with the remarkable development of video and audio information digitization and data compression technology, optical discs have been replaced with VCRs (video cassette recorders) that record / reproduce video / audio information on video cassette tapes, which are magnetic tapes. An optical disk recording / reproducing apparatus (DVD recorder) for recording / reproducing video / audio information on a DVD (digital versatile disk) and a hard disk apparatus (hard disk recorder) for recording / reproducing video / audio information on a hard disk are widely used. ing.

  By the way, a DVD has a capacity of about 4.7 GB per disk, but a hard disk has a capacity of 80 GB to several hundred GB, so the hard disk records long-time information such as a TV program. Suitable for Therefore, hard disk devices are often used to record television programs.

  A television program is recorded using a hard disk device. Examples of the television program include a drama program, a talk program, and a news program. Drama programs are broadcast once, and broadcast on a fixed day of the week, with broadcast periods of 1 to 12 months. Some talk programs are cut once and others are broadcast on a fixed day of the week, and the broadcast period is undecided and continues for many years. In addition, there are news programs that are broadcast at the same time zone from Monday to Friday, those that are broadcast at the same time zone on Saturday, and programs that are broadcast at the same time zone on Sunday.

When recording reservation (recording reservation) is made to the hard disk device to record such a TV program, for a one-time cut program, specify the channel and broadcast date and time to be the recording start time of the day. For example, the recording is started once, and when the recording end time is reached, one recording reservation is made so that the recording is ended. Specify the broadcast day of the week, recording start time and recording end time, and perform periodic recording reservation so that recording starts when the recording start time comes on the specified day of the week, and recording ends when the recording end time comes ing.

  In the conventional hard disk device, a desired TV program is often stored on the hard disk by periodic recording reservation such as recording a TV program that is broadcast regularly such as every week or every day. It is often said that the remaining amount of free space on the hard disk has become low even though you are not watching the TV program recorded on the TV. In this case, for example, the TV program recorded on the hard disk TV programs that are dubbed to a DVD and the original TV program recorded on the hard disk is deleted to increase the remaining free space on the hard disk. If it is not (news program, etc.), delete the TV program and free up hard disk Have or increase the amount.

  By the way, when a TV program that is broadcast regularly such as every week or every day is automatically deleted from the hard disk, the TV program for several broadcasts is left on the hard disk, and the number of old TV programs that have been replayed Although there are cases where automatic deletion is desired, since the conventional hard disk device does not have a function for performing such automatic deletion, there is a problem that it is impossible to deal with a user who desires such automatic deletion.

  In the prior art of Patent Document 1, when making a series reservation, after the dubbing of one DVD is completed, the dubbed information recorded on the hard disk is deleted, or the dubbed information is recorded after all the series recording is finished. Although it is set to delete, etc., user operation is required when dubbing, so hard disk information cannot be automatically deleted, and the above problems can be solved is not.

  In the prior art of Patent Document 2, a reservation erasure operation setting is written in a disk recording medium, so that previously recorded content data is automatically erased according to the setting condition. In addition, setting conditions such as weekly, daily, Monday to Friday, and Monday to Saturday can be selected when the remaining capacity of the disc recording medium is insufficient, or there is reproduced content data as the setting conditions for the reservation erasure means. ing. However, in this prior art, when a TV program that is broadcast regularly such as every week or every day is automatically deleted from the hard disk, a process for leaving a TV program for several broadcasts on the hard disk is disclosed. Therefore, the above problems cannot be solved.

  In the prior art of Patent Document 3, when the free space of the recording medium falls below a predetermined value, the program content main body part included in the broadcast program that has been reproduced is deleted to increase the free space. When a TV program that is broadcast regularly, such as every day, is automatically deleted from the hard disk, there is no disclosure of a process that leaves a TV program for several broadcasts on the hard disk. It cannot solve the problem.

  The present invention has been made to solve the above-described problems. When a TV program broadcast regularly such as every week or every day is automatically deleted from a hard disk, a TV for several times of broadcasting is provided. An object of the present invention is to provide a hard disk device capable of leaving a program on the hard disk.

  In order to achieve the above-mentioned object, the invention of claim 1 sets the number of broadcasts of a previously recorded regular television program when scheduling a regular television program such as weekly or daily. Reservation information registration means for registering reservation information including deletion information for deciding whether or not to delete other TV programs and delete others, and from the deletion information when the recording start time of the regular TV program comes The program number determination means for determining whether or not the obtained number of programs for the remaining number of broadcasts and the number of programs for the number of broadcasts currently remaining on the hard disk are the same, the number of programs for the remaining number of broadcasts and the When it is determined that the number of programs for the number of broadcasts currently remaining on the hard disk is the same, deletion means for sequentially deleting old TV programs based on the deletion information and the remaining capacity of the hard disk, and the remaining broadcasts Recording that records the reserved television program when it is determined that the number of programs of a few minutes is greater than the number of programs of the number of broadcasts currently remaining on the hard disk, or after the old television program is deleted There is provided a hard disk device comprising a control means.

  In this configuration, when making a reservation for recording regular TV programs such as weekly or daily, the remaining TV programs for some of the previously recorded regular TV programs are deleted and others are deleted. Reservation information including deletion information for determining whether or not is registered in the memory. Whether the number of programs for the remaining number of broadcasts obtained from the deletion information is equal to the number of programs for the number of broadcasts currently remaining on the hard disk when the recording start time of the regular TV program comes When the number of programs for the remaining number of broadcasts and the number of programs for the number of broadcasts currently remaining on the hard disk are determined to be the same, the old TV is determined based on the deletion information and the remaining capacity of the hard disk. Sequentially deleted from the program. When it is determined that the number of programs for the remaining number of broadcasts is greater than the number of programs for the number of broadcasts currently remaining on the hard disk, or after the old television program has been deleted, Is done.

  According to this configuration, when a TV program that is broadcast regularly such as every week or every day is automatically deleted from the hard disk, TV programs for several broadcasts can be left on the hard disk. When a continuous drama that was broadcast on the hard disk is recorded on the hard disk, drama for several times of the broadcast is left, so you can check what the previous drama recorded this time was, Can enjoy better. Also, as a result, TV programs that are broadcast regularly, such as every week or every day, are automatically deleted from the hard disk, so when you want to record, there is no more space left on the hard disk. Disappears. Also, for example, if news is recorded, it will not make sense in ordinary homes after a few days, but it will be automatically deleted even if the user does not bother to delete the news. Will improve.

  According to a second aspect of the invention, in the first aspect of the invention, when the reproduction of the television program recorded on the hard disk is finished, the reproduced information indicating that the reproduction of the television program is finished is associated with the program name. Reproduced information storage means for storing in a memory, and when the delete means preferentially deletes a reproduced TV program among old TV programs, the reproduced information corresponding to the program name is stored in the memory. The old TV program recorded on the hard disk is preferentially deleted when it is determined that there is already played information, and when the old TV program is sequentially deleted from the old TV program. Among them, a reproduced TV program can be searched and deleted preferentially.

  In the invention of claim 3, in the invention of claim 1, since the deletion information includes deletion number setting information for setting the number of television programs to be deleted in a plurality of stages according to the remaining capacity of the hard disk, the remaining capacity of the hard disk When there is a large number of TV programs, the number of TV programs to be deleted can be reduced, and when the remaining capacity of the hard disk is small, the number of TV programs to be deleted can be increased. As a result, the hard disk can always ensure an appropriate free space.

  As described above, according to the present invention, when a TV program broadcast regularly such as every week or every day is automatically deleted from the hard disk, it is possible to leave TV programs for several broadcasts on the hard disk. For example, if a continuous drama that was broadcast regularly is recorded on the hard disk, drama for several broadcasts will be left, so it is possible to check what the previous drama recorded this time was Yes, you can enjoy the series drama better. Also, as a result, TV programs that are broadcast regularly, such as every week or every day, are automatically deleted from the hard disk, so when you want to record, there is no more space left on the hard disk. Disappears. For example, if news is recorded, it will not make sense in ordinary households after a few days, but it will be automatically deleted even if the user does not bother to delete the news, improving convenience To do.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram showing a configuration of a hard disk device according to an embodiment of the present invention.

  In FIG. 1, a hard disk device A receives a television broadcast signal via an antenna 1a, selects a television broadcast signal of a desired broadcast station, and a demodulator 2 that demodulates a video / audio signal from the tuner 1. A demodulating unit 3 that demodulates a video / audio signal input from the outside, a compression processing unit 4 that compresses the video / audio signal demodulated by the demodulating unit 2 or the demodulating unit 3 using the MPEG method, and the compressed video / audio signal An HDD (Hard Disk Drive) 5 that writes data to an HD (Hard Disk) 5a and reads video / audio data recorded on the HD 5a, and a decoder unit that decodes the video / audio data read from the HD 5a by the HDD 5 to the original video / audio data. 6 is provided.

  In addition, the hard disk device A also includes video data of the decoded video / audio data (if there is title list screen data or message data from the system controller 10, video on which title list screen data or message data is superimposed). Data) is converted into a displayable video signal and supplied to the display device 81 of the television receiver 8. The audio data among the video and audio data restored by the OSD (on-screen display) unit 7 and the decoder unit 6 is converted from analog to digital. A D / A converter 9 that converts the signal into a signal and supplies the audio signal to the audio output device 82 connected to the speaker 83 of the television receiver 8, during compression processing by the compression processing unit 4, and during decoding processing by the decoder unit 6 ( RAM 15 for temporarily storing video / audio data during decompression processing; A system controller 10 for controlling the operation of the entire device, a key input unit 11 for inputting various key operation signals to the system controller 10, a key receiving unit 12 for receiving various infrared key operation signals from the remote controller 13, and a system A flash ROM 14 in which programs and data necessary for the processing of the controller 10 are recorded is provided.

  As a characteristic element of the present embodiment, the system controller 10 sets the number of broadcasts of a previously recorded regular television program when recording a regular television program such as weekly or daily. Reservation information registration means for registering in the flash ROM 14 reservation information including deletion information for determining whether or not to delete the remaining TV program, and the deletion when the regular TV program recording start time comes Program number determination means for determining whether or not the number of programs for the remaining number of broadcasts obtained from the information and the number of programs for the number of broadcasts currently remaining in the HD 5a are the same, and the number of programs for the remaining number of broadcasts And a deletion procedure for sequentially deleting old TV programs based on the deletion information and the remaining capacity of the HD 5a when it is determined that the number of programs corresponding to the number of broadcasts remaining in the HD 5a is the same. When it is determined that the number of programs for the remaining number of broadcasts is greater than the number of programs for the number of broadcasts currently remaining in the HD 5a, or after the old television program is deleted, And a recording control means for recording the program and when the reproduction of the television program recorded on the HD 5a is finished, the reproduction information indicating that the reproduction of the television program is finished is stored in the flash ROM 14 in association with the program name. A completed information storage means is provided. The deletion means determines whether or not reproduced information corresponding to the program name exists in the flash ROM 14 when the reproduced television program is preferentially deleted among the old television programs, and the reproduced information is determined. When it is determined that there is an old TV program and the old TV program is sequentially deleted, the reproduced TV program is preferentially deleted.

  FIG. 2 is a diagram for explaining processing in the case of deleting a continuous television program recorded on the hard disk in the present embodiment.

  In FIG. 2 (1), 21 is a TV program (title) recorded on the hard disk and recorded on January 1st, and 22 is a TV program recorded on the hard disk and recorded on January 8th. A program (title), 23 is a TV program (title) currently recorded on the hard disk with a recording date of January 15, and 24 is a TV program currently recorded on the hard disk with a recording date of January 22 ( Title). Reference numeral 25 denotes a television program (title) that has not yet been recorded. For example, assuming that today is January 29, this indicates a television program (title) scheduled to be recorded today.

  If these TV programs (titles) 21, 22, 23, 24, 25 are, for example, continuous dramas broadcast on a fixed day of the week, the first broadcast is the TV program (title) 21, 21 The broadcast is a television program (title) 22, the third broadcast is a television program (title) 23, the fourth broadcast is a television program (title) 24, and the fifth broadcast is a television program (title) 25.

  When the television program (title) 25 is recorded on January 29 (today) in a state where the television programs (titles) 21, 22, 23, and 24 are recorded on the hard disk, a predetermined amount of remaining capacity of the hard disk is secured. Therefore, if the first broadcast television program (title) 21 has been reproduced, the television program (title) 21 is deleted and the television program (title) 25 is recorded on the hard disk as shown in FIG. Is done. Therefore, as shown in FIG. 2 (2), the television programs (titles) 22, 23, 24, and 25 become television programs (titles) that remain on the hard disk.

  FIG. 3 is a flowchart for explaining a deletion process that is performed from the time when a television program broadcast regularly such as every week or every day is scheduled for recording until the end of recording in this embodiment. With reference to this flowchart and FIGS. 1 and 2, a description will be given of a deletion process that is performed after a scheduled recording of a television program that is regularly broadcast until the end of the recording.

  After the hard disk device A is turned on and the hard disk device A is started up, when a predetermined operation related to recording reservation of the remote controller 13 is performed, the system controller 10 detects that the recording reservation operation has been performed (step S1). Thus, the recording reservation screen is displayed on the display device 81 of the television receiver 8 (step S2).

  Here, the user operates the remote controller 13 while viewing the recording reservation screen, and inputs reservation information on the recording reservation screen. The input reservation information includes information such as a channel number on which a television program to be recorded is broadcast, a recording date, a recording start time, a recording end time, and a recording mode. In this embodiment, a recording reservation is made. At this time, of the previously recorded regular television programs, deletion information for determining whether to delete the remaining television programs for several broadcasts is included in the reservation information and registered in the flash ROM 14. Hereinafter, a television program recorded on the HD 5a or a recorded television program is referred to as a title.

  As the deletion information, for example, when the remaining capacity of the HD 5a exceeds 20%, the first deletion number setting information that is set to delete the oldest title that has been played back, for example, the remaining HD 5a When the capacity is 20% or less and exceeds 10%, the second deletion number setting information for setting to delete two old titles that have been played, for example, when the remaining capacity of the HD 5a is 10% or less Has third deletion number setting information for setting to delete three old titles that have been reproduced. Any one of the first, second, and third deletion number setting information can be freely selected by the user's operation of the remote controller 13.

  When reservation information including such deletion information is input, the reservation information registration means of the system controller 10 detects that the reservation information has been input (step S3), and registers the reservation information in the flash ROM 14 ( Step S4). With the above processing, the setting of the recording reservation for the television program that is regularly broadcast to be recorded is completed.

  When the system controller 10 detects that the current time measured by a timer (not shown) is the recording start time of the scheduled recording date included in the reservation information (step S5), the program number determination means of the system controller 10 Determines whether the number of programs N corresponding to the number of remaining broadcasts obtained from the deletion information stored in the flash ROM 14 is the same as the number of programs M corresponding to the number of broadcasts currently remaining in the HD 5a ( Step S6).

  For example, the number of programs N for the remaining number of broadcasts obtained by the deletion information is 4, and the number of programs M for the remaining number of broadcasts is 4 as shown in FIG. Since N = M, the deletion means of the system controller 10 preferentially deletes the old program that has been reproduced based on the deletion information and the remaining capacity of the HD 5a.

  In the deletion information, for example, if the first deletion number setting information is set so as to delete the oldest title that has been played when the remaining capacity of the HD 5a exceeds 20%, the system controller 10 The deletion means deletes the oldest title that has been reproduced (step S8) when it is determined that the remaining capacity exceeds 20% with reference to the disc management information of the HD 5a (step S7).

  When deleting the oldest title that has been played, refer to the played information stored in the flash ROM 14 corresponding to the title name by the played information storage means of the system controller 10 when the playback of the title is completed. Thus, the reproduced title is retrieved, the oldest title of the recording date is found from the retrieved reproduced title, and the oldest title is deleted. Therefore, for example, in the example shown in FIG. 2, if the television program (title) 21 is a reproduced title, the recording date is the oldest on January 1, and thus the television program (title) 21 is deleted. Become.

  Thereafter, the recording control unit of the system controller 10 starts recording the title reserved for recording after the oldest title is deleted (step S14). When the recording end time for the title comes, the recording ends. (Step S15), and this process ends. For example, in the example shown in FIG. 2, the television program (title) 25 is recorded after the television program (title) 21 is deleted. As a result, the television programs (titles) 22, 23, 24, and 25 become television programs (titles) that remain on the HD 5a. That is, a regularly broadcast television program is left in the HD5a for four broadcasts.

  In addition, when it is determined in step S6 that N = M, and in the deletion information, for example, when the remaining capacity of the HD 5a is 20% or less and exceeds 10%, When the second deletion number setting information is set so as to delete two old titles, the deletion means of the system controller 10 refers to the disk management information of the HD 5a and the remaining capacity is 10% when the remaining capacity is 20% or less. When it is determined that it exceeds (step S9), two old titles among the reproduced ones are deleted (step S10). However, when deleting two titles, a message such as “Delete two titles and leave three titles, is it okay?” Is displayed on the display device 81 in order to make the user confirm. You may do it.

  The process of deleting two old titles that have been played is performed by searching for the played title by referring to the played information stored in the flash ROM 14 corresponding to the title name at the end of playing the title. Then, two old titles of the recording date are found from the retrieved reproduced titles, and two old titles are deleted from the old title order.

  Thereafter, after the two old titles are deleted, the recording control means of the system controller 10 starts recording the reserved recording title (step S14). When the recording end time for the title comes, the recording is started. The process ends (step S15). For example, in the example shown in FIG. 2, the television program (title) 25 is recorded after the television programs (titles) 21 and 22 are deleted. As a result, the TV programs (titles) 23, 24, and 25 become the new TV programs (titles) remaining in the HD 5a, and the remaining capacity of the HD 5a can be increased as compared with the case where one title is deleted. In addition, a regularly broadcast television program is left in the HD5a for three broadcasts.

  If it is determined in step S6 that N = M, and the remaining information of the HD 5a is 10% or less in the deletion information, for example, three old titles that have been played are deleted. When the third deletion number setting information is set as described above, the deletion unit of the system controller 10 refers to the disk management information of the HD 5a and determines that the remaining capacity is 10% or less (step S11). 3) Delete the three old titles among the reproduced ones (step S12). However, when three titles are to be deleted, a message such as “Delete three titles and leave two titles, is it okay?” Is displayed on the display device 81 in order to make the user confirm. You may do it.

  The process of deleting three old titles among the reproduced ones is performed by searching for the reproduced titles by referring to the reproduced information stored in the flash ROM 14 corresponding to the title names at the end of the reproduction of the titles. Then, three titles with the oldest recording date are found from the retrieved reproduced titles in the order of old titles, and the three old titles are deleted.

  Thereafter, the recording controller of the system controller 10 starts recording the title reserved for recording after the three old titles are deleted (step S14). When the recording end time for the title comes, the recording is started. The process ends (step S15). For example, in the example shown in FIG. 2, the television program (title) 25 is recorded after the television programs (titles) 21, 22, and 23 are deleted. As a result, the TV programs (titles) 24 and 25 become new TV programs (titles) remaining in the HD 5a, and the remaining capacity of the HD 5a can be increased compared to the case where two titles are deleted.

  On the other hand, when it is determined in step S6 that N = M is not satisfied and the number of programs N for the remaining number of broadcasts is determined to be greater than the number of programs M for the number of remaining broadcasts (step S13), The system controller 10 starts recording the title reserved for recording without deleting the title recorded on the HD 5a (step S14). When the recording end time for the title comes, the recording ends (step S15). ), This process ends.

  FIG. 4 is a flowchart for explaining processing in the case of reproducing a title in the present embodiment. Processing for reproducing a title will be described with reference to this flowchart and FIG.

  First, when the user presses the play list key of the remote controller 13 to select a title to be played, the system controller 10 detects that a play list display instruction has been given (step N1), and plays list data from the HD 5a. Is supplied to the display device 81 of the television receiver 8 as a play list screen signal through the processing of the decoder unit 6 and the OSD 7, and thereby the play list screen is displayed on the display device 81 (step S1). N2).

  Then, when the user looks at the play list screen displayed on the display device 81 and designates the title to be played by operating the remote controller 13, the system controller 10 detects that the title to be played is designated ( Step N3), the reproduction list screen is deleted (Step N4), and reproduction of the title is started (Step N5). When the reproduction of the title is completed (step N6), the reproduced information storage unit of the system controller 10 stores the reproduced information indicating that the reproduction of the title is completed in the flash ROM 14 in association with the title name. (Step N7). The reproduced information is used to search for a reproduced title in the processes of steps S8, S10, and S12 of the flowchart shown in FIG.

  As described above, according to the present embodiment, when a TV program that is broadcast regularly such as every week or every day is automatically deleted from the HD 5a, the TV program for several broadcasts may be left in the HD 5a. So, for example, if you record a regular drama that was broadcast regularly on your hard disk, you will be left with several broadcast dramas, so check what the previous drama was recorded this time. Can enjoy the serial drama better. Also, as a result, TV programs broadcast regularly such as every week or every day are automatically deleted from the HD 5a, so that when the user wants to record, the remaining capacity of the HD 5a is lost. Disappears. For example, if news is recorded, it will not make sense in ordinary households after a few days, but it will be automatically deleted even if the user does not bother to delete the news, improving convenience To do.

  The present invention can be used for a title automatic deletion function in a hard disk device. In particular, when a regular TV program is recorded every week or every day, the old TV program can be automatically deleted in order. Thus, it is possible to leave as many television programs as the number of broadcasts desired by the user.
