  Hereinafter, a recording apparatus according to an embodiment of the present invention will be described with reference to FIG.

  The recording apparatus 100 according to the present embodiment includes a receiving unit 102 that acquires a broadcast program (hereinafter referred to as a program) as content via broadcast or the network 101 and EPG (electronic program information) information as information accompanying the broadcast program. It has been. The receiving unit 102 sends the received information to the control unit 103.

  In this embodiment, a program is used as the content. However, any content other than a program, such as music, a still image, and text, may be used.

  In addition, the recording apparatus 100 is provided with a light receiving unit 105 that receives information related to program recording, program reproduction, program dubbing, recording reservation, and the like sent from the remote controller 106 by infrared rays or the like. The light receiving unit 105 sends the received information to the control unit 103.

  The control unit 103 is means for performing processing such as recording, reproduction, and dubbing of a program. Specifically, the control unit 103 sends information such as a received program to the HDD (hard disk) 104 and the HDD 104 records the information. In addition, the control unit 103 sends information such as a program recorded in the HDD 104 to the DVD recording / reproducing unit 107, and causes the DVD recording / reproducing unit 107 to perform recording on the DVD.

  In this embodiment, the HDD 104 is described as a fixed large-capacity recording medium and the DVD is used as a detachable recording medium. However, other than the HDD 104 may be used as a fixed large-capacity recording medium. In addition to the DVD, for example, a memory card may be used as the removable recording medium.

  In addition, when the control unit 103 receives information related to the recording reservation via the light receiving unit 105, the control unit 103 stores the received information in the recording reservation table 108. The recording reservation table 108 is a table that stores information related to recording reservations. Details of the recording reservation table 108 will be described later.

  In addition, when the information such as a program stored in the HDD 104 is dubbed by the DVD recording / reproducing unit 107, the control unit 103 acquires information to be written together with the information such as the program from the media management table 109. The media management table 109 is created based on the recording reservation table 108, and manages information to be recorded for each DVD (media). Details of the media management table 109 will be described later.

  Further, the control unit 103 outputs a program recorded on the HDD 104 and information reproduced by the DVD recording / reproducing unit 107 to a display unit 111 such as a monitor via the output unit 110. Then, information such as a program received by the display unit 111 is displayed.

  In addition, the recording apparatus 100 is provided with an unnecessary part deleting unit 112. The unnecessary part deleting unit 112 deletes an unnecessary part (overlapping part) of a program when dubbing the program onto a DVD. The unnecessary part deleting unit 112 deletes the CM part of the program, the part repeatedly broadcast before and after the CM of the program, the opening and ending of the program, the notice part, and the like.

  Moreover, if the received content is given metadata, the unnecessary part deleting unit 112 deletes the unnecessary part by using the metadata. When metadata is not added, the unnecessary part deleting unit 112 compares the image sound information before and after the CM and extracts an overlapping part. In addition, the unnecessary part deleting unit 112 can extract the ending and the opening by comparing the contents of the first and second contents of the series recording, for example.

  Further, the recording device 100 is provided with a deletion unit 113. The deletion unit 113 determines whether or not to delete the dubbed information recorded in the HDD 104 after dubbing information such as a program to the DVD. The user sets whether or not to delete the dubbed information recorded in the HDD 104 to the deletion unit 113.

  When making a series reservation, the user sets whether to delete dubbed information recorded on the HDD 104 after dubbing one DVD or to delete dubbed information after all series recording ends.

  In addition, the recording apparatus 100 is provided with a dubbing reservation unit 114. The dubbing reservation unit 114 sets the dubbing start time so that dubbing is performed when the recording apparatus 100 is not operating when the recording apparatus 100 is operating and the dubbing process is not immediately started. The dubbing reservation unit 114 measures the time required for dubbing, and compares the measured time with the reservation start time at which the next program recording starts extracted from the recording reservation table 108. Next, based on the comparison result, the dubbing reservation unit 114 determines whether or not the recording process is started before dubbing is completed when dubbing is started. When the dubbing reservation unit 114 determines that the recording process is not started before the dubbing is completed, the dubbing reservation unit 114 performs dubbing. If it is determined that the recording process is started before the end of the dubbing, the dubbing reservation unit 114 detects a period in which the dubbing ends from the end of the next recording to the start of the next recording, and performs the dubbing in that period.

  Next, the recording reservation table 108 will be described with reference to FIG.

  The recording reservation table 108 includes a recording method setting unit 215 for setting a recording method and a program reservation information unit 216 for information on a program to be recorded. The recording method setting unit 215 stores a recording method 201, a title 202, a save destination condition 203, and a condition 204 related to unnecessary part deletion. The recording method 201 relates to a method of recording programs in association with each other. In the example of FIG. Note that the recording method 201 may be any method as long as it records a plurality of programs in association with each other. For example, as the recording method 201, there are genre reservation for grouping programs of the same genre such as sports (more detailed soccer, baseball, etc.), news, and keyword reservation for grouping keywords such as cars, hot springs, and dishes.

  With this recording method 201, the user can set the contents to be dubbed in association with each other. As a result, only necessary contents can be dubbed, the capacity of the DVD can be used efficiently, and time for reproduction and the like can be reduced.

  A title 202 is a title for the recording method 201. Further, the storage destination condition 203 is DVD storage in the example of FIG. 2, but it may be other than DVD as long as it is a removable recording means. Further, in the example of FIG. 2, the condition 204 relating to unnecessary part deletion is CM cut and trailer cut, but there are other overlapping part cuts, endings and opening cuts repeated before and after the CM.

  The program reservation information section 216 includes a date 205, a start time 206, an end time 207, a channel 208, a subtitle 209, a recording flag 210 indicating whether recording has ended, a time (hour / minute), a recording capacity (MB), and the like. Are stored, a storage flag 212 indicating whether or not the storage has been completed, a storage format 213, and a storage destination external media number 214.

  The size 211 is a size after unnecessary parts such as a CM, a trailer, and an overlapping part are cut as necessary.

  In the external media number 214, the control unit 103 calculates and stores the number of programs that can be recorded in the save destination condition 203 from the size 211 and the format 213.

  By referring to the recording reservation table 108 configured in this way, it is possible to grasp information on programs to be collectively stored on the same recording medium, recording status and recording method of the programs to be collectively stored.

  The recording reservation table 108 may be automatically generated by the control unit 103 using EPG or the like based on the series reservation and title information input by the user, or may be generated only from the user input. .

  Next, the media management table 109 will be described with reference to FIG. In addition, the same code | symbol is provided about the already demonstrated part, and detailed description is abbreviate | omitted.

  The media management table 109 is a table for managing information stored for each medium. Specifically, the media management table 109 includes a set of a title 202, an external media number 214, a subtitle 209, a start time 206, an end time 207, a channel 208, a size 211, and a format 213. Is stored.

  The external media number 214 of the media management table 109 and the corresponding title 202, subtitle 209, start time 206, end time 207, channel 208, size 211, and format 213 are referred to. Thus, it is possible to easily grasp what program is recorded for each external medium (DVD) and what information is related to the recorded program.

  Next, the processing of the recording apparatus 100 will be described using the flowchart of FIG.

  First, the recording apparatus 100 receives the program reservation information sent from the remote controller 106 at the light receiving unit 105. Then, the light receiving unit 105 analyzes the received information, converts it into a form that can be decoded by the control unit 103, and sends it to the control unit 103. Then, control section 103 inputs the received reservation information (ST401).

  Here, the reservation information input by the control unit 103 includes a recording method 201 such as a series reservation, a title 202, a storage destination condition 203, a condition 204 related to unnecessary part deletion, a date 205, a start time 206, and an end time. 207, channel 208, subtitle 209, size 211 expressed by time, storage format 213, and the like. These pieces of information are sent via the remote controller 106 based on information from the EPG and condition input from the user.

  Next, control section 103 stores the reservation information input in ST401 in recording reservation table 108 (ST402). As a result, the control unit 103 manages reservation information related to recording.

  Next, when any of the programs reserved for the series is recorded, the control unit 103 completes the recording flag 210 and refers to the size 211 of the recorded program among the programs reserved for the series. Is recorded in time, the recording data amount is calculated from the size 211 and the format 213, and when the size 211 is calculated by the data amount, the total recording data of the recorded program is calculated. The amount is calculated (ST403). Specifically, the control unit 103 refers to the recording flag 210 and the storage flag 212 in the recording reservation table 108, shows that the recording flag 210 indicates that the recording has been completed, and the storage flag 212 does not indicate the storage. Extract programs. Next, the control unit 103 adds the format 213 to the extracted program size 211 and calculates the total amount of recorded data of the programs recorded so far.

  FIG. 5 shows the correspondence between the format 213 and the recordable time for DVD-RAM and DVD-R.

  Note that the control unit 103 may read an accurate recording data amount of the program from the MPEG2 stream header of the program and calculate the cumulative recording data amount.

  Next, the control unit 103 refers to the storage destination condition 203 of the recording reservation table 108 and recognizes the amount of data that can be recorded on the storage medium. Next, control section 103 compares the amount of recognized media data with the total amount of recorded data calculated in ST403 to determine whether the recorded program has the amount of one medium (ST404).

  Then, control section 103 repeats the processes of ST403 and ST404 until the total amount of recorded data reaches one medium.

  When the total amount of recorded data reaches one medium, the control unit 103 displays a message on the display unit 111 as to whether or not the information on the program reserved in the series and recorded on the HDD 104 is to be dubbed to the DVD. Then, confirmation is made with the user (ST405). When the user OKs the dubbing, control unit 103 displays a new media (DVD) insertion message on display unit 111 (ST406).

  In this way, by presenting the start of dubbing to the user, the user can finally confirm dubbing. Further, it is possible to prevent a situation in which dubbing cannot be performed because no DVD is inserted.

  When the user inserts a medium, the control unit 103 performs a process of dubbing information on a program reserved in the series and recorded on the HDD 104 to a DVD.

  First, control section 103 extracts information from recording reservation table 108 and creates media management table 109 (ST407). Thus, the control unit 103 collects information to be recorded on the medium together with the program.

  Next, in the dubbing reservation unit 114, the recording device 100 is playing back a program recorded on the HDD 104, or when dubbing is performed, the recording device 100 overlaps with the next program recording time. It is determined whether or not the dubbing process is immediately started (ST408).

  Specifically, the dubbing reservation unit 114 determines that dubbing cannot be performed immediately when the recording apparatus 100 is currently executing some processing. Further, the dubbing reservation unit 114 measures the time required for dubbing even when the recording apparatus 100 is not currently performing any processing, and the program recording starts after being extracted from the measured time and the recording reservation table 108. Compare the reservation start time. Next, based on the comparison result, the dubbing reservation unit 114 determines whether the recording process is started before dubbing is completed when dubbing is started. When the dubbing is started and the recording process is not started by the end of the dubbing, the dubbing reservation unit 114 determines that the dubbing is started immediately.

  If the dubbing reservation unit 114 determines in ST408 that dubbing cannot be started immediately, the dubbing reservation unit 114 refers to the recording reservation table 108, determines the period during which dubbing ends from the end of recording to the start of recording, and starts the beginning of that period. The time is set as the dubbing start time (ST409).

  In this way, by using the dubbing reservation function recording of the dubbing reservation unit 114, dubbing can be performed in a time zone when the recording apparatus 100 is not used. As a result, it is possible to prevent a situation in which a program reserved for recording due to dubbing cannot be recorded. In the dubbing reservation, time may be specified.

  Next, the unnecessary part deleting unit 112 of the recording apparatus 100 refers to the condition 204 regarding the unnecessary part deletion in the recording reservation table 108 and determines whether or not to delete the unnecessary part of the video at the time of dubbing.

  If it is determined that the unnecessary part is to be deleted, the unnecessary part deleting unit 112 deletes the CM part, the part repeatedly broadcast before and after the CM, the opening / ending of the program, the notice part, etc. (ST410).

  As described above, by deleting a similar part which is an unnecessary part of a program, it is possible to save a program with little overlap. As a result, the program can be stored efficiently, and the time taken to reproduce the dubbed program can be reduced.

  Next, the control unit 103 of the recording apparatus 100 sends the program in which unnecessary portions are deleted as necessary in ST410 and the contents of the media management table 109 to the DVD recording / reproducing unit 107, and the DVD recording / reproducing unit 107 is sent. The dubbed program and the contents of the media management table 109 are dubbed to a DVD (ST411, ST412). Further, the control unit 103 changes the dubbed program storage flag 212 to “completed”.

  In this way, when a series reserved program is recorded for one piece of media, it can be automatically recorded on a DVD. Also, by recording the contents of the media management table on the DVD, the contents of the DVD can be easily grasped and the program can be played back comfortably.

  After the dubbing of the program is completed, the deletion unit 113 of the recording apparatus 100 confirms how the recording content of the HDD 104 is set to be deleted. Then, deletion section 113 deletes the program recorded on HDD 104 according to the confirmed setting (ST413).

  As described above, by deleting the dubbed program recorded in the HDD 104 after the dubbing of the program to the DVD, which is a removable medium, it is possible to avoid a recording failure due to the HDD 104 becoming full.

  As described above, according to the present embodiment, at the stage where series-recorded programs and the like have been accumulated for the capacity of a removable medium such as a DVD, dubbing to the removable medium is proposed to the user, and the dubbing is performed. Can be implemented. Thus, by managing the programs recorded in the HDD 104, the capacity of the HDD 104 can be used effectively. As a result, it is possible to avoid a situation in which the HDD 104 becomes full and the recording fails without the user's knowledge. This is particularly effective in the case where a large amount of contents are reserved together like a series reservation and automatically recorded later.

  Further, according to the present embodiment, since dubbing is performed when data for the capacity of the DVD is stored, the capacity of the DVD can be used effectively, and the number of DVDs to be dubbed can be reduced. Although dubbing is performed when data corresponding to the capacity of the DVD is collected, it is possible to predict the number of broadcasts that can be recorded in advance, such as series reservations, and dubbing each time and deleting a program recorded on the HDD 104 good.

  In this embodiment, the program is used as the content to be recorded. However, the content may be anything such as music, a still image, and text.

  Also, in this embodiment, the description has been given in the form of dubbing to a DVD when a series reserved and the program recorded on the HDD 104 is equivalent to one DVD, but even if it is not a series reserved program, A form in which the cumulative recording data amount of a program, a program having the same keyword, a program set as a group by the user, etc. is dubbed to the DVD may be used.

  Moreover, the form which makes the program which the recording apparatus 100 performs and makes a general purpose computer perform may be sufficient.

  According to the present invention, the capacity of the fixed recording means can be used effectively. In addition, the present invention can be applied to any device that records content, such as a DVD recorder with an HDD or a PC with a TV tuner.
