Description

  The present invention is, for example, a program advertisement or a commercial message (hereinafter abbreviated as CM) information before or after a section between program main program information and program main program information, such as a TV broadcast program, or the like. An information signal in which a plurality of sections of specific information other than main information are allowed to be continuously inserted is recorded on the first recording medium, and the recorded information is recorded on the second recording medium. The present invention relates to an information signal duplication recording method, an information signal duplication recording apparatus, and an information signal recording / reproducing apparatus that perform duplication recording.

  For example, a recording / reproducing apparatus that records an information signal such as a television broadcast program on a recording medium such as a hard disk or a DVD (Digital Versatile Disc) and reproduces the recorded television broadcast program is widely used.

  In such a recording / reproducing apparatus, a function of recording an information signal such as a television broadcast program on a recording medium built in a hard disk or the like, and then copying and recording (hereinafter referred to as dubbing) on a removable recording medium such as a DVD. Some have

  By the way, information signals provided by broadcast media such as TV broadcasts usually include one or a plurality of CMs or program advertisements between main program information and main program information of a broadcast program or before or after main program information. A section of specific information other than the main information of the program is inserted. The section of the specific information is also inserted between the main information and the main information, but the main information and the main information are before the main information from the viewpoint of the subsequent main information.

  In the recording / playback apparatus as described above, when a recorded television broadcast program is played back and viewed, if a scene such as a CM section or a program advertisement section is not desired to be viewed, the user uses a remote commander or the like. There are many cases where high-speed playback is performed by fast-forward playback operation.

  For example, Patent Document 1 (Japanese Patent Laid-Open No. 2005-223666) has a function of jumping (skipping) to a previous scene after a predetermined time, for example, 15 seconds from the current playback position when a predetermined button is pressed during playback. A recording / reproducing apparatus provided is described. In the case of a recording / reproducing apparatus equipped with such a button, when a scene that the user does not want to view is reached, the user operates the button to skip to a scene after a predetermined time for reproduction. can do.

  Thus, since there is a function of skipping the CM section at the time of reproduction, in this type of recording / reproducing apparatus, generally, the information signal of the broadcast program including the main part information and the specific information is the copy source. 1 recording medium. When dubbing, it is common to copy and record in the form of an information signal of a broadcast program including the main information and the specific information, instead of separately handling the main information and the specific information section such as the CM section. .

The above prior art documents are as follows.
JP 2005-223666 A

  Since the conventional recording / reproducing apparatus is configured as described above, since a section of specific information that the user considers unnecessary as an information signal after dubbing is recorded as it is on the duplication destination recording medium, There is a problem that the capacity of the recording medium cannot be used efficiently.

  Further, when the information signal of the broadcast program including the main information and the specific information is dubbed and recorded from the duplication source recording medium to the duplication destination recording medium in this way, the data amount of the information signal to be dubbed is the duplication destination. In such a case, conventionally, for example, a user previously specifies a section of specific information that is considered unnecessary from an information signal to be dubbed in advance. By deleting, the data amount of the information signal to be dubbed is set within the free capacity of the copy destination recording medium, and then dubbing is executed.

  However, it is very troublesome to delete an unnecessary information part in advance, and the process of deleting an unnecessary information part and checking whether it is within the free capacity of the recording medium of the copy destination There is a case where it is necessary to perform the operation several times, and there is a problem that convenience for users is impaired.

It has a function of recording the position information in the information signal to be recorded and the information of the corresponding specific scene section identifier as an additional information file for the information signal of the television broadcast program in a predetermined recording area of the recording medium.

[Hardware Configuration Example of Recording / Reproducing Apparatus of First Embodiment]
FIG. 1 is a block diagram illustrating a hardware configuration example of the recording / reproducing apparatus according to the first embodiment. In FIG. 1, a system controller unit 20 includes a microcomputer, and controls various modes and other operations in the recording / reproducing apparatus of this example.

  The system controller unit 20 is supplied with operation input information through a user input interface unit 21 in accordance with a user operation input using, for example, a remote commander 22 or through an operation button of a recording / reproducing apparatus. The system controller unit 20 determines the input operation input information, and executes processing according to the operation input information.

  A display unit 24 such as an LCD (Liquid Crystal Display) is connected to the system controller unit 20 through a display processing unit 23. The display unit 24 displays display information that serves as a reference when a user inputs an operation. Is done. The user inputs various operations while viewing the display on the display unit 24.

  In this embodiment, particularly when the dubbing mode is selected by a user operation input, a dubbing operation screen is generated by the dubbing user interface generation unit 25 under the control of the system controller unit 20, A dubbing execution pre-process that is displayed on the display screen of the display unit 24 and will be described later is executed.

<Recording system processing>
First, the recording system of the recording / reproducing apparatus of the first embodiment will be described with reference to FIG.
For example, when a user inputs a recording instruction command using the remote commander 22 or through an operation button of the recording / reproducing apparatus, the operation information is supplied to the system controller unit 20 through the user interface unit 21. Under the control of the unit 20, the recording / reproducing apparatus performs the following recording process.

  In this example, the receiving unit 2 includes a television tuner, a video and audio intermediate frequency circuit, and a video and audio detection circuit for receiving terrestrial analog television broadcasts.

  Prior to the above-described command input of the recording instruction, the user performs a channel selection input operation using the remote commander 22 or through the operation button of the recording / reproducing apparatus. Then, the operation information is supplied to the system controller unit 20 through the user interface unit 21, and the system controller unit 20 receives the channel selection control information for selecting a broadcast channel corresponding to the user's channel selection operation. Supply to part 2. At the time of this channel selection, the system controller unit 20 displays the broadcast channel being selected on the display unit 24 through the display processing unit 23, so that the user can perform the channel selection operation while watching the display on the display unit 24. To do.

  The receiving unit 2 receives the channel selection control information, selects and extracts a broadcast program of the broadcast channel selected by the user from the TV broadcast radio wave received by the receiving antenna 1, and receives the audio signal of the selected and extracted broadcast program and Output video signal.

  The audio signal and the video signal of the television broadcast program selected and extracted by the receiving unit 2 are supplied to the recording signal encoding processing unit 3 and are A / D (Analog to Digital) at a predetermined sampling frequency and a predetermined number of quantization bits. ) Conversion signal processing is performed, and the converted digital audio signal and digital video signal are subjected to recording encoding processing.

  Here, as the recording encoding process, the digital audio signal is subjected to a data compression process using a predetermined band compression method such as MPEG audio or AC-3 audio (Dolby AC-3 or Audio Code Number 3). .

  For digital video signals, data compression processing is performed as a recording encoding process by a predetermined band compression method such as MPEG video or wavelet conversion. In this example, MPEG video data compression processing is performed as recording encoding processing for a digital video signal. Then, the video data subjected to the data compression process is multiplexed with the compressed audio data and recorded on the built-in recording medium 5 through the recording processing unit 4.

  In addition, when the user instructs recording to the removable external recording medium 7 instead of the built-in recording medium 5, the recording processing unit 4 performs recording according to a control signal from the system controller unit 20. The multiplexed data from the signal encoding processing unit 3 is recorded on the external recording medium 7 through the external recording medium processing unit 6.

  In this embodiment, identification information (recorded program identification information) is given to the broadcast program to be recorded, and the compressed video data and compressed audio data are added with the recorded program identification information, and the recording medium 5 and the external It is recorded on the recording medium 7. This recorded program identification information is used for retrieval during reproduction.

  Here, the built-in recording medium 5 is configured by a hard disk device in this example, and the external recording medium 7 is a DVD.

  The digital audio signal and the digital video signal from the recording encoding processing unit 3 are supplied to the feature amount detection unit 12 to detect various predetermined feature amounts, and the detected feature amount is used as the specific scene section detection unit. 13 is supplied.

  The feature amount detection performed by the feature amount detection unit 12 is to detect the start point and end point of each CM when a program main part is separated from a CM or program advertisement, and when a plurality of CMs are continuous. For example, detection of a silent interval for an audio signal, detection of a black level interval for a video signal, and the like are used. Also, since the time length of the CM section is a multiple of 15 seconds, such as 15 seconds, 30 seconds, 45 seconds, 60 seconds, etc., the time length of the detected silent section or black level section is 15 seconds. Is also used to detect the CM section.

  In addition, the feature amount detection unit 12 detects not only the feature amount for detecting the break of the specific information section but also the feature amount of the specific information in the specific information section. The resulting feature amount is supplied to the specific scene section identifier generation unit 14. As detection items for the feature amount of the specific information within the specific information section, for example, telop detection, person detection, skin color detection, talk detection, music detection, climax detection, and the like are used. Here, for example, swell detection is performed by detecting a sudden change in volume from a quiet state or a large applause.

  That is, in this example, the feature amount detection unit 12 uses predetermined video data, audio data, and predetermined parameter data to determine predetermined telop feature data (telop section determination data), person feature data, and other image feature data. Various feature amount extraction processes of (image feature section determination data), speaker voice feature data (speaker voice determination data), applause cheer feature data (applause cheer determination data), and other voice feature data are performed.

  In this example, data obtained in the course of the data compression process from the recording encoding processing unit 3 is input to the feature amount detection unit 12. In this example, as will be described later, feature amount detection is also performed on a reproduction signal, and detection of a feature amount is detected using data obtained during the data compression process in consideration of scene change point detection. The specific scene section detection unit 13 detects a scene change point.

  In this way, when performing feature detection and scene change point detection on the playback signal, it is not necessary to completely compress and decode the playback signal to restore the original digital audio data and digital video data. There is a merit that feature amount detection and scene change point detection can be performed using data in the middle of decoding processing, and detection processing is accelerated.

  The specific scene section detection unit 13 detects a specific scene section from the feature amount detected by the feature amount detection unit 12. In this case, as described above, the specific scene section detection unit 13 is not limited to, for example, a section between the program main part and the CM, but a start point and an end point of a program advertisement section in the main part of the program, and a plurality of CMs are consecutive. When this is done, the start point and end point of each CM are detected as specific scene sections. As described above, in the case of this example, the detection information of the specific scene section includes the position information of the start point and end point of the CM, program advertisement, and the main part of the program (for example, the start position of the broadcast program including the CM and the program advertisement). Reference frame number (or field number).

  When the received broadcast program information includes information such as the program title and the program genre, the feature amount detection unit 12 also includes the program title and genre information in the specific information section. It is detected as a feature amount for detection and sent to the specific scene section detection unit 13. Therefore, the specific scene section detection unit 13 detects the section of the specific information using the program title and genre information.

  Detection position information of the specific scene section detected by the specific scene section detection unit 13 is supplied to the specific scene section identifier generation unit 14. Information on the feature amount regarding the specific information of the specific scene section detected by the feature amount detection unit 12 is also supplied to the specific scene section identifier generation unit 14.

  Further, the feature quantity storage unit 15 stores the feature quantity of the specific scene section detected by the specific scene section detection unit 13 based on the feature quantity detected by the feature quantity detection unit 12 in the past, as a specific scene section identifier. Are stored in association with each other. However, the feature quantity storage unit 15 stores only one feature quantity of a scene to which the same specific scene section identifier is assigned. The feature amount data is stored after being compressed.

  The specific scene section identifier generation unit 14 detects the specific scene section as shown in FIG. 2 under the control of the system controller unit 20 at the time of recording on the first recording medium as a duplication source or prior to dubbing. A specific scene section identifier is assigned to each detection position information of the specific scene section from the unit 13.

  Note that “prior to dubbing” may be any time as long as dubbing is performed after recording of an information signal on the first recording medium as a duplication source. For example, dubbing recording is performed during dubbing. Prior to this, an identifier assigning process for a specific scene section may be performed. In this embodiment, the process of assigning an identifier of a specific scene section and the process of recording it as an additional information file on the first recording medium are performed at the time of recording on the first recording medium.

  In this case, the specific scene section identifier generation unit 14 obtains the feature amount of the specific scene section to which the specific scene section identifier is to be assigned from the feature amount detection unit 12.

  Then, the specific scene section identifier generation unit 14 sequentially compares the acquired feature amount of the specific scene section with the data obtained by decompressing the feature amount stored in the feature amount storage unit 15. When it is determined that there is the same feature value among the feature values stored in 15, the specific scene section corresponds to the feature value determined as the same feature value in the feature value storage unit 15. The specific scene section identifier stored in this way is given.

  Further, the specific scene section identifier generation unit 14 is the same as the feature amount of the specific scene section acquired from the feature amount detection unit 12 in the data expanded from the feature amount stored in the feature amount storage unit 15. When it is determined that there is nothing to be determined, a new specific scene section identifier is given to the specific scene section. Then, the new specific scene section identifier and the feature amount data obtained by compressing the feature amount of the specific scene section are additionally stored in the feature amount storage unit 15.

  Here, the feature quantity used to generate the specific scene section identifier is partially different from the feature quantity used to detect the specific scene section. For example, feature quantities such as scene changes, information such as program titles and program genres are used as information for generating a specific scene section identifier even if they are used to detect a specific scene section. The feature amount information used to generate the specific scene section identifier is for expressing the characteristics of the specific scene section to which the specific scene section identifier is to be assigned, and includes a person or a telop. Or whether music is playing.

  The specific scene section identifier generation unit 14 detects the specific scene section detection position information (specific information) detected by the specific scene section detection unit 13 as described above when recording or when generating a specific scene section identifier prior to dubbing. The position information of the scene section) and the specific scene section identifier generated for the specific scene section are associated with each other as shown in FIG.

  Under the control of the system controller unit 20, the recording processing unit 4 records an additional information file including information that associates the position data of the specific scene section with the specific scene section identifier in association with the recording data of the broadcast program. Recording is performed in a predetermined recording area of the medium 5, in this example, an additional information file area.

  Alternatively, the position data of the specific scene section and the specific scene section identifier from the specific scene section identifier generation unit 14 are supplied from the recording processing unit 4 to the external recording medium processing unit 6, and recording processing is performed by the external recording medium processing unit 6. Then, the data is recorded in a predetermined recording area of the external recording medium 7, in this example, the additional information file area.

  In this case, the additional information file composed of the position data of the specific scene section and the specific scene section identifier is associated with the video data and audio data of the corresponding broadcast program by the recording program identification information described above, and built-in recording The information is recorded in the additional information file area of the medium 5 or the external recording medium 7.

  In this embodiment, as described above, the position data of the specific scene section is obtained by using the frame number (or field number) of the broadcast program to be recorded. And the frame position (or field position) of the audio data.

  FIG. 3 is a diagram for explaining a specific scene section in the broadcast program information as an information signal and the assignment of an identifier thereof. In the information signal of this example, as shown in FIGS. 3A and 3B, three specific scene sections SC1 to SC3 are inserted before the program main information 1, and program main information 1 and program main information 2 are inserted. , Three specific scene sections SC4 to SC6 are inserted, and after the main program information 2, three specific scene sections SC7 to SC9 are inserted.

  In the example of FIG. 3, the specific scene sections SC1 and SC9 are program advertisements to which the same specific scene section identifier IDa is assigned. The specific scene sections SC2, SC6, and SC8 are CM1 assigned the same specific scene section identifier ID1, and the specific scene sections SC3 and SC5 are CM2 assigned the same specific scene section identifier ID2. Sections SC4 and SC7 are cases in which CM3 is assigned the same specific scene section identifier ID3.

  As the additional information file, as shown in FIG. 2, the position information of each specific scene section SC1 to SC9 and the specific scene section identifiers IDa and ID1 to ID3 are recorded correspondingly. .

  Note that the position data of the specific scene section and the information of the specific scene section identifier from the specific scene section identifier generating unit 14 are not recorded as an additional information file but supplied to the multiplexing processing unit in the recording signal encoding processing unit 3. Then, it may be multiplexed with video data and audio data subjected to compression encoding processing and recorded in a predetermined recording area of the recording medium 5 or the external recording medium 7.

  Note that the processing of the feature amount detection unit 12, the specific scene section detection unit 13, and the specific scene section identifier generation unit 14 may be software processing by a microcomputer of the system controller unit 20.

<Reproduction system processing>
Next, the reproduction system of the recording / reproducing apparatus of this example will be described with reference to FIG.
The user interface 21 and the remote commander 22 of the recording / playback apparatus of this embodiment have a playback mode switching button for switching between a normal playback mode and a short playback mode in which a section of specific information such as CM is skipped to shorten the playback time. Prepare. Alternatively, the recording / reproducing apparatus may be provided with a normal reproduction button for designating the normal reproduction mode and a short-time reproduction button for designating the short-time reproduction mode. Alternatively, when the short-time playback mode is designated, a button for designating short-time playback may be operated in addition to the normal playback button.

  Next, the processing operation in the playback mode will be described. The user inputs a command for instructing to start any of the playback modes using the remote commander 22 or through the operation button of the recording / playback apparatus. Then, the operation information is supplied to the system controller unit 20 through the user interface unit 21. Under the control of the system controller unit 20, the recording / reproducing apparatus performs the following reproduction process.

  When the user inputs a playback instruction in the normal playback mode from the recording medium 5 or the external recording medium 7 through the remote commander 22, for example, it is input into the system controller unit 20 through the user input interface unit 21. Upon receiving this user input, the system controller unit 20 controls the read control unit 8 to perform the normal reproduction mode. In the following description, for example, a case where the recording medium 5 is selected by the user as the recording medium will be described.

  In the reproduction mode, the reproduction processing unit 9 reads out the compressed video data and the compressed audio data of the broadcast program designated for reproduction by the user from the recording medium 5 and supplies the reproduction decoding output unit 10.

  In the reproduction decoding output unit 10, the video data and audio data of the reproduced broadcast program are separated into video data and audio data. The separated compressed audio data is subjected to a predetermined decoding process corresponding to a signal processing method in which band compression processing is performed at the time of recording, and a digital audio signal obtained by the decoding process is subjected to D / A (Digital to Analog) conversion. Then, the signal is output as an analog audio signal through the output terminal 11a.

  Also, in the reproduction decoding output unit 10, the separated compressed video data is subjected to a predetermined decoding process corresponding to a signal processing system subjected to a band compression process at the time of recording and converted into a digital video signal, and then D / A conversion Processing is performed and an analog video signal is output through the output terminal 11v.

  Further, the additional information file recorded on the recording medium 5 is read from the recording medium 5 by the reproduction processing unit 9 and supplied to the additional information file processing unit 16. In the additional information file processing unit 16, the position data of the specific scene section and the information of the specific scene section identifier are extracted and supplied to the system controller unit 20. However, in the normal playback mode, the information is not used. .

  The recording / reproducing apparatus of this embodiment also has a special reproduction function that uses the additional information file recorded in the recording medium 5 or the recording medium 7 to skip the CM section or the program advertisement section. Since it has nothing to do with the gist of the present invention, detailed description is omitted here.

<Dubbing process>
In the first embodiment, as the dubbing mode, only one information of a specific scene section to which the same identifier is assigned is recorded as in the simple dubbing mode in which the recorded broadcast program information signal is copied and recorded as it is. And a compressed dubbing mode capable of compressing the recorded data amount after copying, so that the user can select any dubbing mode according to user input operation information through the user input interface unit 21. Has been.

  For example, when the information signal recorded on the recording medium 5 composed of a hard disk as the first recording medium is as shown in FIG. 4A, this recording information signal is recorded on the external recording medium 6 by dubbing. As an example, the above two dubbing modes will be described.

  The recording information signal in FIG. 4A is composed of four pieces of main information 1, 2, 3, 4 and three CM sections CM1 to CM3 as specific scene sections. Three CM sections CM1 to CM3 are repeatedly inserted as appropriate. Note that this recording information signal has been subjected to data compression processing as described above.

  In this embodiment, as shown in the additional information file on the lower side of FIG. 4A, the additional information file including the specific scene section identifier and the position information of the corresponding specific scene section is stored in the recording medium 5. Are recorded in association with the recording information signal.

  In this embodiment, in any dubbing mode, constant-speed dubbing capable of performing dubbing recording while reproducing all of the recording data and dubbing recording of the compressed recording data as the compressed data are performed. High-speed dubbing is possible, and which dubbing is performed depends on the selection by the user's operation input.

[Simple dubbing mode]
In constant-speed dubbing in the simple dubbing mode, the recording information signal data shown in FIG. 4A is read from the recording medium 5 under the control of the system controller unit 20 based on the user operation input, and the reproduction processing unit 9 Then, the compression is decompressed by the reproduction decoding output unit 10. The compressed and decompressed recording information signal data is supplied to the recording encoding processing unit 3.

  After the dubbing recording of the data of the recording information signal is completed, the additional information file corresponding to the recording information signal is read from the recording medium 5 and supplied to the recording processing unit 4 through the reproduction processing unit 9. The data of the additional information file input to the recording processing unit 9 is recorded and dubbed on the external recording medium 7 through the recording processing unit 4 and through the external recording medium processing unit 6.

  Next, in high-speed dubbing in the simple dubbing mode, the data of the recording information signal shown in FIG. 4A is read from the recording medium 5 under the control of the system controller unit 20 based on the user operation input, and reproduction processing is performed. The compressed data is supplied to the recording processing unit 4 through the unit 9.

  The compressed data of the recording information signal supplied to the recording processing unit 4 is supplied to the external recording medium 7 through the external recording medium processing unit 6 and is dubbed and recorded.

  After the dubbing recording of the data of the recording information signal is completed, the additional information file corresponding to the recording information signal is read from the recording medium 5 and supplied to the recording processing unit 4 through the reproduction processing unit 9. The data of the additional information file input to the recording processing unit 9 is recorded and dubbed on the external recording medium 7 through the recording processing unit 4 and through the external recording medium processing unit 6.

  As is apparent from the above description, in this simple dubbing mode, the data amount before and after dubbing does not change.

[Compression dubbing mode]
In constant-speed dubbing in the compression dubbing mode, the recording information signal data shown in FIG. 4A is read from the recording medium 5 under the control of the system controller 20 based on the user operation input, and the reproduction processing unit 9 Then, the compression is decompressed by the reproduction decoding output unit 10. The compressed and decompressed recording information signal data is supplied to the recording encoding processing unit 3.

  Prior to reading out the recording information signal, the additional information file of the recording information signal shown in the lower side of FIG. 4A is read out and supplied to the additional information file processing unit 16 through the reproduction processing unit 9. Temporarily held in that buffer. The system controller unit 20 refers to the additional information file and monitors the position of each CM section as a specific scene section in the recording information signal.

  When the system controller unit 20 refers to the additional information file and determines that it is a dubbing recording section of the main information of the recording information signal, the recording encoding processing unit 3 again inputs the data of the input recording information signal. The compression encoding process is performed, and the compressed and encoded data is controlled to be recorded and dubbed on the external recording medium 6 through the recording processing unit 4 and the external recording medium processing unit 6.

  When the system controller unit 20 refers to the additional information file and determines that the input recording information signal of the recording encoding processing unit 3 is the head position of the specific scene section, the reading control unit 8, the reproduction processing unit 9, The reproduction decoding unit 10 and the recording encoding processing unit 3 are controlled to temporarily stop reading of data from the recording medium 5 and to temporarily stop decoding and encoding processing of recording data.

  Then, the system controller unit 20 controls the reading control unit 8 to jump the reading position of the recording medium 5 to the end point of the specific scene section of the recording information signal, that is, the start position of the next main information. . Then, the pause of the read control unit 8, the reproduction processing unit 9, the reproduction decoding unit 10, and the recording encoding processing unit 3 is released, and the next main program information is dubbed and recorded in the same manner as described above.

  In this way, as shown in FIG. 4B, only the main information is collected and dubbed and recorded, except for the information of the specific scene section between the main information and the main information. At this time, the information on the position where the specific scene section between the main information and the main information existed is stored and held.

  In this way, after the process of recording only the main information is completed, the system controller unit 20 uses the information of the specific scene section included in the recording information signal as the main information in the example of FIG. After the collective recording, the dubbing recording is performed collectively.

  That is, by referring to the additional information file, the position of the specific scene section in the recording information signal can be known. Therefore, only the part indicated by the position information of the specific scene section is read from the recording medium 5 and dubbing of the main information is performed. Dubbing is recorded in the same manner as recording.

  In this case, in this embodiment, all the information of the specific scene section included in the recording information signal is not dubbed and recorded, but the specific scene section having the same identifier is referred to by referring to the additional information file. Only one is dubbed. In the case of the example in FIG. 4, since the recording information signal includes only three types of CM1, CM2, and CM3, the information of these three types of CM1, CM2, and CM3 is dubbed and recorded.

  And at the time of this compression dubbing, the information of the position where the specific scene section between the main part information and the main part information stored is present, the specific scene section identifier of the specific scene section existing at the position, The recording address on the external recording medium for the information (video information and audio information) of the specific scene section is generated as a duplicate additional information file and recorded in correspondence with the dubbed recording information signal.

  Incidentally, the association between the recording information signal recorded by dubbing and the duplicate additional information file is made, for example, by identification information of the recording information signal recorded by dubbing.

  FIG. 5 shows an example of a duplicate additional information file. In the example of FIG. 5, for example, the main information 1 and the main information 2 are separated by frame (or field) numbers between 900 and 901, between 24300 and 24301, and so on. The three CM sections indicated by the identifiers ID1, ID2 and ID3 respectively exist.

  As shown in FIG. 5, in this example, the information on the three CM sections indicated by the identifiers ID1, ID2, and ID3 is recorded in the duplicate additional information file on the external recording medium 7. A recording address (comprising a pair of a recording start address and a recording end address of information of each CM section) is included.

  The duplicate additional information file is not limited to the example of FIG. 5. For example, the correspondence file of the specific scene section existence position and the specific scene section identifier, the specific scene section identifier, and the information of the specific scene section It may be configured to be separated into a file corresponding to the recording address.

  The duplicate additional information file is used when information of a specific scene section is inserted between main part information and main part information at the time of reproducing an information signal recorded by dubbing.

  Next, also in the high-speed dubbing in the compression dubbing mode, as shown in FIG. 4B, the main story information and the information of the specific scene section are separated and recorded, and the information of the specific scene section has the same identifier. Only one is recorded. However, in the high-speed dubbing in the compression dubbing mode, there is a problem of a method of detecting and separating the main information and the specific scene section.

  In this embodiment, as described above, MPEG video data compression is performed on a digital video signal, so that in high-speed dubbing, dubbing processing is performed in units of GOP (Group Of Pictures), which is a data unit for a plurality of frames. To do. Then, referring to the additional information file for each GOP, the GOP including the head of the specific scene section is detected, and the dubbing of one main part information is finished with the GOP including the head of the specific scene section. The dubbing of the next main information is started from the GOP including the end of the specific scene section.

  Further, the dubbing of information on each specific scene section starts from a GOP including the head of the specific scene section and ends with a GOP including the end of the specific scene section.

  Then, as the location information of the specific scene section of the duplicate additional information file, as in the case of constant-speed dubbing in the compression dubbing mode, the end frame of the main information before the position where the specific scene section exists, the specific scene This is the first frame of the main information after the position where the section exists.

  However, when synthesizing the main part information and the information of the specific scene section at the time of reproduction, the information of the end or the first GOP unit of the main part information and the information of the GOP unit of the start or the end of the information of the specific scene section Both are decoded, and the main information and the information of the specific scene section are switched at the time of the frame (field) where the specific scene section exists in the GOP.

  The dubbed information signal includes correspondingly recorded dubbing mode information indicating that the information signal has been dubbed recorded and in which dubbing mode the dubbing mode is recorded together with the dubbed information signal. Has been.

  The above description is also about the case of dubbing from the recording medium 5 to the external recording medium 7. Conversely, the video recorded on the external recording medium 7 in the mode shown in FIG. When the audio data and the additional data file are recorded, the same dubbing process can be performed even when the additional information file is copied and recorded on the recording medium 5.

[Description of Main Operation Processing in Recording / Reproducing Apparatus of First Embodiment]
Next, main operation processing in the recording / reproducing apparatus of the first embodiment configured as described above will be described with reference to the flowcharts of FIGS. The processing of each step of the flowchart described below is mainly executed under the control of the microcomputer that constitutes the system controller unit 20.

  That is, as shown in FIG. 6, the system controller unit 20 monitors whether there is a user operation input by monitoring the output of the user input interface unit 21 (step S1). When it is determined that there has been a user operation input, the system controller unit 20 determines whether or not the user operation input is a broadcast program recording start operation (step S2) and determines that the user operation input is a recording start operation. Sometimes, the recording process routine, the feature amount detection, the specific scene section detection, and the specific scene section identifier generation routine are executed in parallel (step S3).

  Then, the system controller unit 20 monitors whether or not a user operation for stopping recording has been performed (step S4). When no user operation for stopping recording is detected, the system controller unit 20 returns to step S3 to perform a recording process routine, feature amount detection, and identification. When it is determined that a user operation for stopping recording is performed in parallel with the scene section detection and the specific scene section identifier generation routine, the post-recording process is executed (step S5), and the process returns to step S1.

  In the post-recording process in step S5, the system controller unit 20 records the position data of the specific scene section detected by the specific scene section detection unit 13 and the information of the specific scene section identifier as an additional information file. It is recorded on a recording medium in association with the recording data of the program. In this case, the additional information file is associated with the recorded data of the recorded broadcast program based on the recorded broadcast program identification information.

  In addition, the additional information file is not recorded as post-recording processing, but the detection result of the specific scene section detection and the information of the specific scene section identifier performed in real time in parallel with the recording processing are stored in the recording area of the additional information file. In the post-recording process, the detection result of the specific scene section detection performed in real time in parallel with the recording process and the information of the specific scene section identifier itself are included in the additional information file. Instead of recording, the specific scene section detection unit 13 further examines the detection result of the specific scene section detection performed in parallel with the recording process, detects a more specific scene section, and more likely The position information of the specific scene section and the specific scene section identifier are included in the additional information file and recorded.

  Next, when it is determined in step S2 that the operation input is not a recording start operation, the system controller unit 20 determines whether or not the operation input is a dubbing instruction (step S11 in FIG. 7). Is determined, it is determined which of the simple dubbing mode and the compressed dubbing mode is selected (step S12).

  When it is determined in this step S12 that the selected mode is the simple dubbing mode, the system controller unit 20 executes the dubbing process in the simple dubbing mode described above (step S13). Return to step S1 of step 6.

  If it is determined in step S12 that the selected mode is the compression dubbing mode, the system controller unit 20 determines whether the dubbing speed mode is constant speed dubbing or high speed dubbing (step S14). ).

  When it is determined in step S14 that constant speed dubbing is performed, the system controller unit 20 executes the above-described constant speed dubbing process (step S15), and returns to step S1 in FIG. If it is determined in step S14 that the high-speed dubbing is performed, the system controller unit 20 executes the above-described high-speed dubbing process (step S16), and returns to step S1 in FIG.

  If it is determined in step S11 that the operation input is not a dubbing instruction, the system controller unit 20 determines whether or not the operation input is a reproduction start instruction operation in a reproduction mode (step S17).

  When it is determined in step S17 that the operation input is a reproduction start instruction operation in the reproduction mode, the system controller unit 20 executes the above-described reproduction processing operation (step S18), and after the completion, step S1 in FIG. Returning to step S1, the processes after step S1 are repeated.

  If it is determined in step S17 that the operation input is not a reproduction start instruction operation in the reproduction mode, other processing corresponding to the operation input is executed (step S19). Then, after that process, the process returns to step S1, and the processes after step S1 are repeated.

  Next, a parallel processing routine of recording processing, feature amount detection, specific scene section detection, and specific scene section identifier generation processing executed in step S3 of FIG. 6 will be described with reference to the flowchart of FIG.

  First, the system controller unit 20 takes in data to be recorded (step S21). That is, when the data to be recorded is broadcast program information (video information and audio information) from the reception unit 2, the system controller unit 20 performs recording signal encoding processing on the broadcast program information selectively received by the reception unit 2. Instruct the unit 3 to supply.

  Next, the system controller unit 20 instructs the recording signal encoding processing unit 3 to perform recording encoding processing of broadcast program information (step S22), and controls the recording processing unit 4 to be selected and designated by the user. Video information and audio information of the broadcast program subjected to the recording and encoding process are recorded on one of the recording medium 5 and the external recording medium 7 (step S23).

  Then, the system controller unit 20 determines whether or not a recording end instruction has been given by the user (step S24), and when determining that the recording end instruction has not been made, the system controller unit 20 returns to step S21 and continues the recording process.

  Steps S21 to S24 constitute a recording processing routine. In parallel with this recording processing routine, a feature amount detection, a specific scene section detection, and a specific scene section identifier generation processing routine are performed. In other words, the system controller unit 20 instructs the feature amount detection unit 12 to supply the data to be recorded captured in step S21 and also instructs the feature amount detection unit 12 to execute the feature amount detection process. (Step S25). As described above, in this example, the data being compressed from the recording signal encoding processing unit 3 is supplied to the feature amount detection unit 12.

  In response to this execution instruction, the feature amount detection unit 12 executes detection of the various feature amounts described above, and supplies the processing results to the specific scene section detection unit 13. The specific scene section detection unit 13 receives the execution instruction from the system controller unit 20, and executes the above-described specific scene section detection process (step S26). Then, the system controller unit 20 stores and holds the feature amount data detected by the feature amount detection unit 12 and the position data of the specific scene section detected by the specific scene section detection unit 13 in a built-in buffer memory or the like. (Step S27). Here, the feature amount data detected by the feature amount detection unit 12 is also stored and retained in order to regenerate a more probable specific scene section.

  Then, the system controller unit 20 determines whether or not a recording end instruction has been given by the user (step S28), and when determining that the recording end instruction has not been made, the system controller unit 20 returns to step S15 to detect the feature amount and to detect the specific scene. The section detection and specific scene section identifier generation processing is continued.

  Note that the determination processing in step S24 and the determination processing in step S18 are actually the same determination processing, not separate determination processing, but here, since two processing routines are described in parallel, As shown in FIG. 8, it is described separately in two discrimination steps.

  When the system controller unit 20 determines in step S24 or step S28 that the user has instructed recording termination, the system controller unit 20 instructs the specific scene section detection unit 13 to specify the feature amount data held in the buffer memory and the specific amount data. Using the position data of the scene section, the recording medium 5 or the recording medium 7 generates the position information of the more specific scene section to be recorded together with the recording data of the broadcast program, and generates the specific scene section identifier. Is performed (step S29).

  Then, as shown in FIG. 2, the system controller unit 20 provides the recording processing unit 4 with the additional information file including the position information of the specific scene section generated in step S29 and the information of the specific scene section identifier. Is recorded in the recording medium on which the recording data of the broadcast program is recorded in a state in which the recording data is associated with the recording data of the broadcast program (step S30).

  Next, the specific scene section identifier generation processing in step S29 in FIG. 8 will be described with reference to the flowchart in FIG. In this example, the process of each step in the flowchart of FIG. 9 is executed by the specific scene section identifier generation unit 14 under the control of the system controller 20. Note that the microcomputer of the system controller 20 may be configured to include the function of the specific scene section identifier generation unit 14 as software.

  First, the system controller unit 20 designates the first specific scene section (step S31), the position information of the specific scene section held in the buffer memory for the specific scene section identifier generation unit 14, The feature amount of the specific scene section specified by the position information of the specific scene section is passed (step S32).

  The specific scene section identifier generation unit 14 compares the acquired feature amount of the specific scene section with the feature amount of the specific scene section identifier assigned in the past stored in the feature amount storage unit 15 (step S33). . At this time, since the feature amount stored in the feature amount storage unit 15 is compressed, the specific scene section identifier generation unit 14 decompresses the compression and compares it with the acquired feature amount of the specific scene section.

  Then, the specific scene section identifier generation unit 14 determines whether or not the feature quantity determined to be the same as the acquired feature quantity of the specific scene section is in the one stored in the feature quantity storage unit 15. (Step S34).

  When it is determined in step S34 that the feature quantity determined to be the same as the acquired feature quantity of the specific scene section is in the one stored in the feature quantity storage unit 15, the feature quantity storage unit 15 stores the feature quantity. The specific scene section identifier assigned to the feature amount determined to be the same is assigned to the acquired specific scene section (step S35).

  If it is determined in step S34 that the feature quantity determined to be the same as the acquired feature quantity in the specific scene section is not present in the stored feature quantity storage unit 15, a new one is created. A specific scene section identifier is generated and assigned to the specific scene section (step S36), and the generated and assigned new specific scene section identifier and the feature amount of the specific scene section are stored in the feature amount storage unit 15. (Step S37).

  Then, after step S35 or step S37, the system controller unit 20 proceeds to step S38, and whether or not the generation process of the specific scene section identifier for the last specific scene section of the recorded broadcast program has ended. If it is determined that the process has not ended, the next specific scene section is designated (step S39), the process returns to step S32, and the processes after step S32 are repeated.

  If it is determined in step S38 that the generation process of the specific scene section identifier for the last specific scene section of the recorded broadcast program has been completed, the specific scene section identifier generation and giving process routine is ended. Return to the recording processing routine of No. 8. As described above, the system controller unit 20 ends the specific scene section identifier generation and assignment processing routine, as shown in FIG. 2, and the specific scene section position information and the specific scene section identifier of the specific scene section. Is associated with the recording data of the corresponding broadcast program and recorded as an additional information file.

[Example of generation method of specific scene section identifier]
In the above description, it is determined whether the specific scene section identifier is the same as the feature quantity detected in the past by using the feature quantity in the feature quantity detection unit 12, and if it is the same, the same specific scene section identifier is used. If different, a new specific scene section identifier is assigned, and each specific scene section identifier and feature quantity are stored in the feature quantity storage unit 15 in association with each other. In this case, as the specific scene section identifier, for example, an identification number or the like can be assigned by assigning it.

  However, in this case, since the specific scene section identifier and the feature amount need to be stored in the recording medium and the feature amount storage unit 15, the capacity of the feature amount storage unit 15 becomes large and the recording medium is added. There is a problem that the area of the information file becomes large.

  As a method of reducing this problem, in this embodiment, a method of forming a specific scene section identifier using the feature amount itself is used. According to this method, since it is only necessary to store the feature quantity as the specific scene section identifier, it is possible to reduce an increase in the storage capacity of the feature quantity storage unit 15.

  FIG. 14 illustrates an example of a method for generating a specific scene section identifier using a feature amount. In FIG. 14, for the sake of simplicity of explanation, a specific scene section identifier for a scene consisting of a section of 10 frames will be described as a case where two feature evaluation values (feature quantities) are generated. Here, the feature evaluation value 1 is, for example, the presence / absence of a person, and the feature evaluation value 2 is, for example, the presence / absence of a telop character.

  In the 10-frame scene section shown in FIG. 10A, the feature evaluation value 1 changes as shown in FIG. 10B, and the feature evaluation value 2 changes as shown in FIG. Suppose you make a change.

  In this example, the feature evaluation value 1 and the feature evaluation value 2 each obtain a difference in the time direction. Then, the difference results between the feature evaluation value 1 and the feature evaluation value 2 are as shown in FIGS. 10D and 10E, respectively.

  The specific scene section identifier is generated by performing run-length encoding compression on the difference result. That is, in the example of FIG. 10, the high level value is “A”, the low level value is “B”, and the length of each value in the time axis direction is expressed by a numerical value. it can. In the case of the example of FIG. 10, the feature evaluation value 1 can be represented as “A1B4A2B3” for the scene, and the feature evaluation value 2 can be represented as “A1B1A2B6” for the scene. The specific scene section identifier is constituted by a compressed value of each of the plurality of feature evaluation values.

  According to this example, the specific scene section identifier detection unit 14 restores the original feature evaluation value from the compressed value of each feature evaluation value, and detects the feature amount in the scene section detected by the specific scene section detection unit 13. By comparing with the corresponding feature evaluation value detected by the unit 12, it is possible to determine whether or not the scenes can be given the same specific scene section identifier.

  In this example, since the specific scene section identifier is the feature amount data of the scene section, the data capacity stored in the feature amount storage unit 15 can be reduced, and the area of the additional information file on the recording medium can be reduced. It can be done.

  The method for generating the specific scene section identifier using the feature amount data as it is is not limited to the above-described method, and various methods can be employed. If the recording capacity and the storage capacity may be large, the feature data itself can be used as the specific scene section identifier.

[Constant dubbing in compression dubbing mode]
Next, the constant speed dubbing processing operation in the compression dubbing mode in step S15 in FIG. 7 will be described with reference to the flowcharts in FIGS.

  First, the system controller unit 20 accepts designation of broadcast program content to be dubbed (step S41). At this time, in this example, although not shown, a list of broadcast program contents that can be dubbed recorded on the recording medium 5 is displayed on the display screen of the display unit 24, and the broadcast program content of the display screen is displayed. From the list, designation of broadcast program content to be dubbed by the user through the user input interface unit 21 is accepted.

  Next, the system controller unit 20 reads the recorded data of the broadcast program content while pre-reading the position information and the specific scene section identifier of the specific scene section of the additional information file of the broadcast program content dubbed from the recording medium 5. Start (step S42).

  Then, the system controller unit 20 decompresses and decodes the recording data of the designated broadcast program content in the reproduction decode output unit 10, supplies the decompressed decode output to the recording encoding processing unit 3, and performs compression encoding again. (Step S43).

  In parallel with this, the system controller unit 20 refers to the position information of the specific scene section of the additional information file for the broadcast program content designated for dubbing, and monitors the start point of the specific scene section (step S44). If it is not the start point of the specific scene section, control is performed so that the encoded recording data is recorded on the external recording medium 7 that is the dubbing destination (step S45).

  Then, the system controller unit 20 determines whether or not the dubbing of the main information of the broadcast program content designated for dubbing has been completed (step S46). If it is determined that the dubbing has not ended, the system controller unit 20 returns to step S42, and this step S42 The subsequent processing is repeated.

  When it is determined in step S44 that the start point is the specific scene section, the system controller unit 20 temporarily stops reading, decoding, and encoding of the recording data of the broadcast program content designated for dubbing (step S47). Then, the system controller unit 20 jumps the reading position of the recording data from the recording medium 5 from the start point to the end point of the specific scene section (step S48), and temporarily stores the existence position information of the specific scene section (step S49). ). Then, the system controller unit 20 resumes reading, decoding, and encoding from the recording medium 5 (step S50), returns to step S44, and repeats the processing after step S44.

  If it is determined in step S46 that the dubbing of the main information of the content designated for dubbing has been completed, constant-speed dubbing processing of the information of the specific scene section is performed. That is, the system controller unit 20 refers to the additional information file and refers to the specific scene section identifier of the first specific scene section in the dubbed information signal (step S51 in FIG. 12).

  Then, the system controller unit 20 compares and contrasts the specific scene section identifier of the specific scene section with a specific scene section identifier stored in a recorded memory, which will be described later. As information on the specific scene section of the recorded content, it is checked whether or not it is information on the specific scene section already recorded in the external recording medium 7 (step S52), and whether or not it has been recorded as the check result. A determination is made (step S53).

  When it is determined in step S53 that an unrecorded specific scene section has already been recorded, the system controller unit 20 determines whether or not there is a specific scene section that is not recorded in the dubbing-designated information signal. (Step S60). When it is determined in step S60 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S61). Then, the process returns to step S52, and the processes after step S52 are repeated.

  If it is determined in step S53 that the unrecorded specific scene section has not been recorded, the system controller unit 20 sets the read position from the recording medium 5 as the start point of the specific scene section (step S54). The recording data of the specific scene section is read out, the read-out recording data is decompressed and decoded, the decompressed decoded output is subjected to recording encoding processing, and control is performed so as to perform dubbing recording on the external recording medium 7 (step S55). ).

  Then, the system controller unit 20 refers to the additional information file, monitors the end point of the specific scene section (step S56), and continues step S55 until the end point is reached. When the end point of the specific scene section during dubbing recording is determined in step S56, the system controller unit 20 temporarily stops reading from the recording medium 5, decoding and encoding (step S57).

  Then, the system controller unit 20 writes and stores the specific scene section identifier of the recorded specific scene section in a recorded memory (not shown in FIG. 1) (step S58).

  Then, as shown in FIG. 6, the system controller unit 20 temporarily holds the recording start address and end address of the recorded specific scene section in association with the existence position information and the specific scene section identifier ( Step S59). Then, it returns to step S60 and repeats the process after this step S60.

  When it is determined in step S60 that there are no unrecorded specific scene sections on the recording medium 5, the system controller unit 20 stores the position information of the recorded specific scene section temporarily stored in step S59 and the identification thereof. Correspondence information between the scene section identifier and the recording start address and end address on the external recording medium 7 is generated as a duplication additional information file (see FIG. 6) and recorded on the external recording medium 7 as a dubbing destination (step). S62).

  This completes the dubbing process for one of the contents designated to be dubbed. Next, the system controller unit 20 determines whether there is a broadcast program content that has been dubbed and has not been recorded (step S63). If there is no broadcast program content, dubbing termination processing is performed (step S64). In the dubbing end process, for example, a process of clearing the recorded memory is performed.

  If it is determined in step S63 that there is another broadcast program content that has been dubbed and has not been recorded, the process returns to step S42 in FIG. 11 and the processes in and after step S42 are repeated.

[High-speed dubbing in compressed dubbing mode]
Next, the high-speed dubbing processing operation in the compression dubbing mode in step S16 in FIG. 7 will be described with reference to the flowcharts in FIGS.

  First, the system controller unit 20 accepts designation of broadcast program content to be dubbed (step S71). At this time, in this example, although not shown, a list of broadcast program contents that can be dubbed recorded on the recording medium 5 is displayed on the display screen of the display unit 24, and the broadcast program content of the display screen is displayed. From the list, designation of broadcast program content to be dubbed by the user through the user input interface unit 21 is accepted.

  Next, the system controller unit 20 reads the recorded data of the broadcast program content while pre-reading the position information and the specific scene section identifier of the specific scene section of the additional information file of the broadcast program content dubbed from the recording medium 5. Start (step S72).

  In this high-speed dubbing, the recording data is dubbed in units of GOP without being subjected to decompression decoding and recompression encoding processing, so the system controller unit 20 reads the recording data from the recording medium 5 in units of GOP, The recording data is supplied to the recording processing unit 4 through the reproduction processing unit 9, and control is performed to perform dubbing recording on the external recording medium 7 through the external recording medium processing unit 6 (step S73).

  Then, the system controller unit 20 determines whether or not the GOP unit data is a GOP including the start point of the specific scene section (step S74), and determines that the data is not a GOP including the start point of the specific scene section. Then, it is determined whether or not the dubbing of the main program information of the broadcast program content designated for dubbing has been completed (step S77). If it is determined that the dubbing has not been completed, the process returns to step S73, and the processes after step S73 are repeated.

  When it is determined in step S74 that the GOP includes the start point of the specific scene section, the system controller unit 20 determines the read position of the recording data after the dubbing of the data in the GOP unit is completed. The data position in GOP units including the end point of the section is set (step S75), and the position information of the GOP is held as management information for reproduction (step S76). And it progresses to step S77 and performs the process after this step S77.

  Through the processing up to step S77 described above, high-speed dubbing of the main information about the designated broadcast program content can be performed. If it is determined in step S77 that the dubbing of the main information of the designated broadcast program content has been completed, high-speed dubbing processing of information on the specific scene section is performed. That is, the system controller unit 20 refers to the additional information file and refers to the specific scene section identifier of the first specific scene section in the dubbed information signal (step S81 in FIG. 14).

  Then, the system controller unit 20 compares and contrasts the specific scene section identifier of the specific scene section with a specific scene section identifier stored in a recorded memory, which will be described later. As information on the specific scene section of the recorded content, it is checked whether it is information on the specific scene section already recorded on the external recording medium 7 (step S82), and whether or not it has been recorded as the check result. A determination is made (step S83).

  If it is determined in step S83 that the unrecorded specific scene section has already been recorded, the system controller unit 20 refers to the additional information file and specifies the unrecorded specific scene section. It is determined whether or not there is a scene section (step S90). When it is determined in step S90 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S91). Then, the process returns to step S82, and the processes after step S82 are repeated.

  If it is determined in step S83 that the unrecorded specific scene section has not been recorded, the system controller unit 20 determines the read position from the recording medium 5 as GOP unit data including the start point of the specific scene section. (Step S84), recording data in GOP units in the specific scene section is read out, and the read recording data is controlled to be dubbed and recorded on the external recording medium 7 (step S85).

  Then, the system controller unit 20 refers to the additional information file, monitors the GOP including the end point of the specific scene section (step S86), and continues step S85 until the GOP includes the end point. When the GOP including the end point of the specific scene section during dubbing recording is determined in step S86, the system controller unit 20 temporarily stops reading from the recording medium 5 (step S87).

  Then, the system controller unit 20 writes and stores the specific scene section identifier of the recorded specific scene section in a recorded memory (not shown in FIG. 1) (step S88).

  Then, the system controller unit 20 associates the recording start address and end address of the recorded specific scene section with the GOP existence position information of the start point and end point of the specific scene section and the specific scene section identifier. Is temporarily stored as management information during reproduction (step S89). Thereafter, the system controller unit 20 returns to step S90 and determines whether or not there is a specific scene section that is not recorded.

  When it is determined in step S90 that there is no unrecorded specific scene section in the recording medium 5, the system controller unit 20 generates the reproduction management information temporarily stored in step S89 as a duplicate additional information file. Then, recording is performed on the external recording medium 7 which is the dubbing destination (step S92).

  This completes the dubbing process for one of the contents designated to be dubbed. Next, the system controller unit 20 determines whether or not there is a broadcast program content that has been dubbed and has not been recorded (step S93), and if there is not, dubbing termination processing is performed (step S94). In the dubbing end process, for example, a process of clearing the recorded memory is performed.

  If it is determined in step S93 that there is another broadcast program content that has been dubbed and has not been recorded, the process returns to step S73 in FIG. 13 and the processes in and after step S73 are repeated.

  Although omitted in the above description, the dubbing mode information indicating whether the recording data after dubbing is simple dubbing or compression dubbing is associated with the dubbing mode information as accompanying information. It is recorded. Further, the dubbing speed information indicating whether the recording data is compressed dubbed or is dubbed at high speed is also associated with the recorded data after dubbing as accompanying information. Are recorded.

[Playback processing]
Next, the reproduction processing operation in step S18 in FIG. 7 will be described with reference to the flowchart in FIG.

  First, the system controller unit 20 determines whether or not the content to be played back has been compressed dubbed (step S101). When it is determined that the content has not been compressed dubbed, it is not dubbed or is simply dubbed. If it is determined that the data is compressed and dubbed, reproduction corresponding to the compressed dubbing is executed.

  That is, when it is determined in step S101 that the compression dubbing has not been performed, the system controller unit 20 determines whether or not an instruction to start normal reproduction (normal speed reproduction) has been given (step S102). If the instruction is for the special playback mode, the designated other playback process is executed (step S106). Here, other playback processes include high-speed playback and digest playback in which only a specific section is extracted using an additional information file. However, since this is not directly related to the present invention, here Detailed description is omitted.

  When it is determined in step S102 that a normal playback start instruction has been issued, the system controller unit 20 reads the recording data of the designated broadcast program from the recording medium 5 or 7 on which the reproduction target designated by the operation input is recorded. Then, the additional information file is read and normal speed reproduction is started (step S103).

  Next, the system controller unit 20 determines whether or not the program to be played has been played to the end (step S104), and when it is determined that the program has been played to the end, executes a playback end process (step S113).

  If it is determined in step S104 that the reproduction has not been completed, the system controller unit 20 determines whether or not a reproduction end instruction operation has been performed by the user (step S105), and the reproduction end instruction operation is performed by the user. If it is determined that it is not, the process returns to step S103 and the normal reproduction process is continued. If it is determined in step S105 that the user has performed a reproduction end instruction operation, a reproduction end process is executed (step S114).

  On the other hand, when it is determined in step S101 that the content to be reproduced is compressed and dubbed, the system controller unit 20 determines whether or not there is an instruction to start normal reproduction (step S107). If the instruction is for another special playback mode, the designated other playback process is executed (step S108).

  When it is determined in step S107 that a normal playback start instruction has been received, the system controller unit 20 reads the recording data of the specified broadcast program from the recording medium 5 or 7 on which the playback target specified by the operation input is recorded. The duplicate additional information file is read out and normal speed reproduction is started (step S109).

  As described above, the recording data of the information signal recorded by compression dubbing has the main program information and the information of the specific scene section separated from each other. Therefore, in this step S109, the system controller unit 20 records the recording data to be reproduced. The main story information is read from the recording medium and playback is started.

  Then, the system controller unit 20 determines based on the position information of the specific scene section of the duplicate additional information file whether or not the position of the specific scene section between the main program information and the main program information has been reached (step S110). When it is determined that the position of the specific scene section has been reached, the system controller unit 20 pauses the reading of the main part information, and performs reproduction processing of information on the specific scene section at the position of the specific scene section (step S111). ).

  In step S111, different processing is performed depending on whether the compression dubbing is performed with constant speed dubbing or the high speed dubbing.

  When the content to be reproduced is one that has been dubbed at a constant speed, the system controller unit 20 refers to the duplicate additional information file and identifies the specific scene section to be inserted at the position and the specific identifier indicated by each identifier. The recording address of the scene section information is recognized in advance before the insertion position arrives. When the insertion position is reached, the system controller unit 20 reads information on a specific scene section to be inserted from the recording address and sequentially reproduces the information. When the system controller unit 20 has completed all the information of the specific scene section to be inserted, the system controller unit 20 resumes the reading of the main information that has been paused from the stopped position.

  In addition, when the content to be played back is high-speed dubbed, the system controller unit 20 basically performs the same processing as constant-speed dubbing, but the connection between the main information and the information of the specific scene section. The connection between the information on the specific scene section and the information on the specific scene section is different from that in the case of constant speed dubbing.

  That is, the system controller unit 20 performs high-speed dubbing in units of GOPs, and connects between the main part information and the information of the specific scene section, and between the information of the specific scene section and the information of the specific scene section. In the portion, the information before and after being connected includes the same information in GOP units. For this reason, when the last GOP unit data of the information before the connection is reproduced, the first GOP unit data of the information after the connection is also reproduced together, and at the joint frame (field) in the middle of the GOP. The information before and after is switched by switching the information before and after.

  After the process of step S111, the system controller unit 20 determines whether or not the program to be played has been played to the end (step S112), and when it is determined that the program has been played to the end, executes a playback end process (step S112). Step S114).

  If it is determined in step S112 that the reproduction has not been completed, the system controller unit 20 determines whether or not a reproduction end instruction operation has been performed by the user (step S113), and the reproduction end instruction operation is performed by the user. If it is determined that it is not, the process returns to step S109 to continue the normal reproduction process. If it is determined in step S113 that the user has performed a reproduction end instruction operation, a reproduction end process is executed (step S114).

  Note that as an example of other reproduction processing in step S108, reproduction processing using a duplicate additional information file is conceivable. In this embodiment, the dubbed recording data includes main story information and specific scene section information. In this case, since only the information of one specific scene section is inserted between the main program information and the main program information, the information of the specific scene section is inserted between the main program information and the main program information. There is a merit that special reproduction such as reproduction can be easily performed.

  In the above description, when the information signal is recorded on the recording medium 5 as the first recording medium, the additional information file is also generated and recorded. However, this is performed at the time of specific reproduction. Alternatively, it may be performed prior to duplication recording during duplication recording.

[Second Embodiment]
In the first embodiment described above, at the time of dubbing recording, duplication of specific scene sections is eliminated for each broadcast program content, thereby reducing the data amount. For this reason, when there is little overlap of the specific scene section in one broadcast program content, the data amount reduction effect is small.

  In the second embodiment, when the dubbing designation includes a plurality of broadcast program contents, the duplication recording that overlaps the same specific scene section is excluded for all of the plurality of broadcast program contents. Reduce the amount of data.

  In the second embodiment, the hardware configuration of the recording / reproducing apparatus is the same as that of the first embodiment, as shown in FIG. The recording process to 5 is the same as that of the first embodiment.

  When one broadcast program content is designated as a dubbing target, the substance of the recording data on the recording medium dubbed in the second embodiment is the recording data when dubbed in the first embodiment. However, when a plurality of broadcast program contents are designated as a dubbing target, the data amount after dubbing recording can be reduced as described below.

  For example, a case where two broadcast program contents A and broadcast program contents B as shown in FIG. 16 are designated as one dubbing target will be described. As shown in FIG. 16, each of the broadcast program content A and the broadcast program content B includes three types of CMs, that is, CM1, CM2, and CM3, as information of a specific scene section. FIG. 16 shows a state where the broadcast program content A and the broadcast program content B are recorded on the recording medium 5 and the additional information file is recorded correspondingly.

  In the second embodiment, when these two broadcast program contents A and B are designated as dubbing targets, first, only the main information of the two contents A and B is as shown in FIG. Dubbing recording is performed in the same manner as in the first embodiment. After that, the information of the specific scene section that exists in common in these two contents A and B is one, the information of the specific scene section, in this example, after the main information of the two contents A and B To record.

  In this case, the duplicate additional information file includes a content A additional information file, a content B additional information file, and a specific scene section recording address information file common to the two contents A and B.

  As shown in FIG. 18, the additional information file for content A and the additional information file for content B are associated with the recording data of each content by the identification information of the corresponding content, and for each content. Provided.

  On the other hand, as shown in FIG. 19, the specific scene section recording address information file is recorded in association with the recording data of the plurality of contents by the identification information of the plurality of corresponding contents.

  In this way, in the case of the first embodiment, information on three types of specific scene sections needs to be recorded independently for content A and content B, respectively. In the case of the second embodiment, it is only necessary to record information of three types of specific scene sections in common for a plurality of contents A and B, and data after dubbing recording can be reduced.

  Processing operations for constant speed dubbing and high speed dubbing in the second embodiment will be described below with reference to the drawings.

[Constant dubbing in compression dubbing mode]
First, the constant speed dubbing processing operation in the compression dubbing mode in the second embodiment will be described with reference to the flowcharts of FIGS.

  Of the constant-speed dubbing processing operation in the compression dubbing mode of the second embodiment shown in FIGS. 20 and 21, the processing in step S121 to step S130 is completely the same as the processing from step S41 to step S50 in FIG. It is the same.

  That is, in the second embodiment, first, the system controller unit 20 receives designation of broadcast program content to be dubbed (step S121). At this time, in this example, although not shown, a list of broadcast program contents that can be dubbed recorded on the recording medium 5 is displayed on the display screen of the display unit 24, and the broadcast program content of the display screen is displayed. From the list, designation of broadcast program content to be dubbed by the user through the user input interface unit 21 is accepted.

  Next, the system controller unit 20 reads the recorded data of the broadcast program content while pre-reading the position information and the specific scene section identifier of the specific scene section of the additional information file of the broadcast program content dubbed from the recording medium 5. Start (step S122).

  Then, the system controller unit 20 decompresses and decodes the recording data of the designated broadcast program content in the reproduction decode output unit 10, supplies the decompressed decode output to the recording encoding processing unit 3, and performs compression encoding again. (Step S123).

  In parallel with this, the system controller unit 20 monitors the start point of the specific scene section with reference to the position information of the specific scene section of the additional information file for the broadcast program content designated for dubbing (step S124). If it is not the start point of the specific scene section, control is performed so that the encoded recording data is recorded on the external recording medium 7 that is the dubbing destination (step S125).

  Then, the system controller unit 20 determines whether or not the dubbing of the main program information of the broadcast program content designated for dubbing has been completed (step S126). When it is determined that the dubbing has not been completed, the system controller unit 20 returns to step S122 and returns to step S122. The subsequent processing is repeated.

  Further, when it is determined in step S124 that it is the start point of the specific scene section, the system controller unit 20 temporarily stops reading, decoding and encoding of the broadcast program content designated for dubbing (step S127). Then, the system controller unit 20 jumps the reading position of the recording data from the recording medium 5 from the start point to the end point of the specific scene section (step S128), and temporarily stores the existence position information of the specific scene section (step S129). ). Then, the system controller unit 20 resumes reading, decoding, and encoding from the recording medium 5 (step S130), returns to step S124, and repeats the processing after step S124.

  In the second embodiment, when it is determined in step S126 that the dubbing of the main information of the content designated for dubbing has been completed, the constant speed of the information of the specific scene section is immediately determined as in the first embodiment. Instead of proceeding to the dubbing process, a content additional information file for which the main information dubbing shown in FIG. 18 has been completed is generated and temporarily held (step S131).

  Then, it is determined whether there is any other broadcast program content designated to be dubbed (step S132), and if there is, the process returns to step S122, and the processes after step S122 are repeated.

  With the above processing, dubbing recording of only main information of a plurality of broadcast program contents designated for dubbing is completed. When the dubbing recording of only the main information of the plurality of broadcast program contents is completed, the system controller unit 20 refers to the additional information file, and information on specific scene sections for the plurality of broadcast program contents designated for dubbing. Dubbing recording.

  That is, when it is determined in step S132 that there is no other dubbing-designated broadcast program content, the system controller unit 20 refers to the additional information file, and the first specific scene section in the dubbing-designated information signal The specific scene section identifier is referred to (step S141 in FIG. 21).

  Then, the system controller unit 20 compares and contrasts the specific scene section identifier of the specific scene section with a specific scene section identifier stored in a recorded memory, which will be described later. As information on the specific scene section of the recorded content, it is checked whether or not it is information on the specific scene section already recorded in the external recording medium 7 (step S142), and whether or not it has been recorded as the check result. A determination is made (step S143).

  If it is determined in step S143 that the unrecorded specific scene section has already been recorded, the system controller unit 20 determines whether or not there is a specific scene section that is not recorded in the dubbed information signal. (Step S150). When it is determined in step S150 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S151). Then, the process returns to step S142, and the processes after step S142 are repeated.

  When it is determined in step S143 that the unrecorded specific scene section is not recorded, the system controller unit 20 sets the read position from the recording medium 5 as the start point of the specific scene section (step S144). The recording data of the specific scene section is read out, the read recording data is decompressed and decoded, the decompressed decoded output is subjected to recording encoding processing, and control is performed so as to perform dubbing recording on the external recording medium 7 (step S145). ).

  Then, the system controller unit 20 refers to the additional information file, monitors the end point of the specific scene section (step S146), and continues step S145 until the end point is reached. When the end point of the specific scene section during dubbing recording is determined in step S146, the system controller unit 20 temporarily stops reading from the recording medium 5, decoding, and encoding (step S147).

  Then, the system controller unit 20 writes and stores the specific scene section identifier of the recorded specific scene section in a recorded memory (not shown in FIG. 1) (step S148).

  Then, as shown in FIG. 19, the system controller unit 20 temporarily stores the recording start address and end address of the recorded specific scene section in association with the specific scene section identifier (step S149). Thereafter, the process returns to step S150, and it is determined whether or not there is an unrecorded specific scene section on the recording medium 5.

  When it is determined in step S150 that there are no unrecorded specific scene sections on the recording medium 5, the system controller unit 20 stores the content for each broadcast program content temporarily stored in step S131 as shown in FIG. Additional information file, the specific scene section identifier of the recorded specific scene section temporarily stored in step S149, and the recording start address and end address on the external recording medium 7 as shown in FIG. A specific scene section recording address information file made up of correspondence information is generated as a duplicate additional information file (see FIG. 17) and recorded on the external recording medium 7 as a dubbing destination (step S152).

  This completes the dubbing process for the plurality of broadcast program contents designated for dubbing, and the system controller unit 20 performs the dubbing termination process (step S153). In the dubbing end process, for example, the temporary holding information in step S131 and the temporary holding information in step S149 are cleared and the recorded memory used in step S148 is cleared.

[High-speed dubbing in compressed dubbing mode]
Next, the processing operation of high-speed dubbing in the compression dubbing mode in the second embodiment will be described with reference to the flowcharts of FIGS.

  Of the high-speed dubbing processing operation in the compressed dubbing mode of the second embodiment shown in FIGS. 22 and 23, the processing from step S161 to step S167 is exactly the same as the processing from step S71 to step S77 in FIG. It is.

  In other words, in the second embodiment, first, the system controller unit 20 receives designation of broadcast program content to be dubbed (step S161). At this time, in this example, although not shown, a list of broadcast program contents that can be dubbed recorded on the recording medium 5 is displayed on the display screen of the display unit 24, and the broadcast program content of the display screen is displayed. From the list, designation of broadcast program content to be dubbed by the user through the user input interface unit 21 is accepted.

  Next, the system controller unit 20 reads the recorded data of the broadcast program content while pre-reading the position information and the specific scene section identifier of the specific scene section of the additional information file of the broadcast program content dubbed from the recording medium 5. Start (step S162).

  In this high-speed dubbing, the recording data is dubbed in units of GOP without being subjected to decompression decoding and recompression encoding processing, so the system controller unit 20 reads the recording data from the recording medium 5 in units of GOP, Control is performed to supply the recording data to the recording processing unit 4 through the reproduction processing unit 9 and to perform dubbing recording on the external recording medium 7 through the external recording medium processing unit 6 (step S163).

  Then, the system controller unit 20 determines whether or not the GOP unit data is a GOP including the start point of the specific scene section (step S164), and determines that the data is not a GOP including the start point of the specific scene section. Then, it is determined whether or not the dubbing of the main information of the broadcast program content designated for dubbing has been completed (step S167). If it is determined that the dubbing has not been completed, the process returns to step S163, and the processing from step S163 onward is repeated.

  When it is determined in step S164 that the GOP includes the start point of the specific scene section, the system controller unit 20 sets the read position of the recording data after the dubbing of the data in the GOP unit is completed, as the specific scene. The GOP unit data position including the end point of the section is set (step S165), and the position information of the GOP is held as management information for reproduction (step S166). And it progresses to step S167 and performs the process after this step S77.

  In the second embodiment, when it is determined in step S167 that the dubbing of the main information of the content designated for dubbing has been completed, the high-speed dubbing of the information of the specific scene section is immediately performed as in the first embodiment. Instead of proceeding to the process, the content additional information file in which the main information dubbing shown in FIG. 18 is completed is generated and temporarily held (step S168).

  Then, it is determined whether there is any other broadcast program content designated to be dubbed (step S169), and if there is, the process returns to step S162, and the processes after step S162 are repeated.

  With the above processing, dubbing recording of only main information of a plurality of broadcast program contents designated for dubbing is completed. When the dubbing recording of only the main information of the plurality of broadcast program contents is completed, the system controller unit 20 refers to the additional information file, and information on specific scene sections for the plurality of broadcast program contents designated for dubbing. Dubbing recording.

  That is, in step S169, when it is determined that there is no other dubbing designated broadcast program content, the system controller unit 20 refers to the additional information file and information signals of a plurality of dubbing designated broadcast program contents. The specific scene section identifier of the first specific scene section is referred to (step S171 in FIG. 23).

  Then, the system controller unit 20 compares and contrasts the specific scene section identifier of the specific scene section with a specific scene section identifier stored in a recorded memory, which will be described later. It is checked whether it is information on a specific scene section already recorded on the external recording medium 7 as information on the specific scene section of the recorded content (step S172), and whether or not it has been recorded as the check result. Determination is made (step S173).

  In step S173, when it is determined that the unrecorded specific scene section has already been recorded, the system controller unit 20 refers to the additional information file and specifies the unrecorded specific scene section. It is determined whether or not there is a scene section (step S180). When it is determined in step S180 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S181). Then, the process returns to step S172, and the processes after step S172 are repeated.

  If it is determined in step S173 that the unrecorded specific scene section has not been recorded, the system controller unit 20 determines the read position from the recording medium 5 as GOP unit data including the start point of the specific scene section. (Step S174), the recording data of the GOP unit in the specific scene section is read out, and the read recording data is controlled to be dubbed and recorded on the external recording medium 7 (step S175).

  Then, the system controller unit 20 refers to the additional information file, monitors the GOP including the end point of the specific scene section (step S176), and continues step S175 until the GOP includes the end point. When the GOP including the end point of the specific scene section during dubbing recording is determined in step S176, the system controller unit 20 temporarily stops reading from the recording medium 5 (step S177).

  Then, the system controller unit 20 writes and stores the specific scene section identifier of the recorded specific scene section in a recorded memory (not shown in FIG. 1) (step S178).

  Then, the system controller unit 20 temporarily stores the recording start address and the end address of the recorded specific scene section, and the specific scene section recording address information corresponding to the specific scene section identifier as one of the management information at the time of reproduction. (Step S179). Thereafter, the system controller unit 20 returns to step S180 and determines whether or not there is a specific scene section that is not recorded.

  When it is determined in step S180 that there is no unrecorded specific scene section on the recording medium 5, the system controller unit 20 stores the content for each broadcast program content temporarily stored in step S168 as shown in FIG. Additional information file, the specific scene section identifier of the recorded specific scene section temporarily stored in step S178, and the recording start address and end address on the external recording medium 7 as shown in FIG. A specific scene section recording address information file composed of correspondence information is generated as a duplicate additional information file and recorded in the external recording medium 7 that is a dubbing destination (step S182).

  This completes the dubbing process for the plurality of broadcast program contents designated for dubbing, and the system controller unit 20 performs the dubbing termination process (step S183). In the dubbing termination process, for example, the temporary holding information in step S168, the temporary holding information in step S179, the recorded memory used in step S178, and the like are performed.

  Although omitted in the above description, the dubbing mode information indicating whether the recording data after dubbing is simple dubbing or compression dubbing is associated with the dubbing mode information as accompanying information. It is recorded. Further, the dubbing speed information indicating whether the recording data is compressed dubbed or is dubbed at high speed is also associated with the recorded data after dubbing as accompanying information. Are recorded.

[Third Embodiment]
The third embodiment is a development of the second embodiment. That is, in the second embodiment, the information of a specific scene section is handled in common for a plurality of broadcast program contents designated for dubbing, and the recorded data after dubbing is further reduced.

  In the third embodiment, the information of a specific scene section is handled in common for all the dubbed contents recorded on the copy destination recording medium, not for each group of contents designated for dubbing.

  That is, a recording area for recording information on a specific scene section (specific scene section information group recording area) is separately provided on the recording medium as a copy destination, and dubbing recording is performed on the recording medium in the specific scene section information group recording area. Information on a specific scene section included in the broadcast program content is recorded without duplication.

  In the specific scene section information group recording area, a specific scene section recording address information file associating the specific scene section identifier and its recording address as shown in FIG. 19 is recorded together. . However, in the case of the third embodiment, the specific scene section recording address information file does not need to have a correspondence relationship with a plurality of contents as shown in FIG. Will be associated with the dubbing content.

  In the case of the third embodiment, step S148 in FIG. 21 and step S178 in FIG. 23 are not necessary, and recording of a specific scene section newly dubbed and recorded in step S149 in FIG. 21 and step S179 in FIG. The address and the recording end address are additionally recorded in the specific scene section recording address information file as recording address information.

  In step S142 in FIG. 21 and step S172 in FIG. 23, whether or not the scene is a dubbed specific scene section is determined by referring to the specific scene section identifier in the specific scene section recording address information file. .

  According to the third embodiment, the information of the specific scene section is handled in common for all the broadcast program contents dubbed and recorded on the recording medium, so there is no duplication and the recording capacity can be used efficiently. .

[Fourth Embodiment]
The fourth embodiment should be said to be a modification of the third embodiment. That is, in the fourth embodiment, the duplication source information signal is recorded on the duplication source first recording medium in the same format as the duplication destination recording data described in the third embodiment. To. For this reason, in the fourth embodiment, the processing at the time of duplication becomes simple.

  FIG. 24 is a diagram for explaining the recording data of the copy source information signal in the fourth embodiment. In this example as well, the information signal is a broadcast program content.

  In the fourth embodiment, the recording of the original information signal on the first recording medium includes an initial recording process and a post-process.

  The initial recording process is exactly the same as the recording of the original information signal in the above-described embodiment. As shown in FIG. 24A, the information signal including the specific scene section is directly detected while detecting the specific scene section. The process of recording includes the process of generating a specific scene section identifier and generating and recording an additional information file.

  The post process is a process of re-recording the information signal recorded in the initial recording process while referring to the additional information file generated during the initial recording process. By re-recording by this post-processing, the broadcast program content which is the information signal of this example is separated into main program information and specific scene section information as shown in FIG. 1 recording medium is provided with a specific scene section information group recording area separately, and the information of the specific scene section is used as a specific scene section information group common to the recording source information signal to be recorded. Record in the recording area without duplication.

  Then, in the post processing, for each broadcast program content of the copy source, as shown in FIG. A correspondence information file with a specific scene section identifier is recorded. Further, as information for managing the information of the specific scene section recorded in the specific scene section information group recording area, as shown in FIG. 4B, correspondence information between the specific scene section identifier and the recording address information thereof A specific scene section recording address information file consisting of is recorded.

  The information recorded on the first recording medium by the initial recording process may be left as it is, or may be deleted after the post-processing is completed.

  When recording data after the initial recording process is kept, dubbing recording is performed using the recording data after the love initial recording process in the simple dubbing mode, and post-processing recording is performed in the compression dubbing mode. It is possible to perform dubbing recording using data.

  On the other hand, when the recorded data after the initial recording process is erased, the simple dubbing mode process becomes a problem. The simple dubbing mode can be executed by performing constant-speed dubbing while inserting the disc.

  The recording data processing to the first recording medium in the fourth embodiment will be described with reference to the flowcharts of FIGS. This example of the recording data processing is recording data processing to the recording medium 5 as an example of the first recording medium, and corresponds to the processing in step S3 of the flowchart shown in FIG. The processing from S191 to S200 is exactly the same as the processing from S21 to S30 shown in FIG.

  However, in the fourth embodiment, the recording is not terminated in the process of step S200 corresponding to step S30, but the process up to step S200 is the initial recording process, and thereafter, FIG. 26 and FIG. The post-processing as shown in Fig. 2 continues.

  That is, when the process up to step S200 is completed and the initial recording process is completed, the system controller unit 20 stores the position information of the specific scene section of the additional information file of the broadcast program content recorded from the recording medium 5 by the initial recording process, and While pre-reading the specific scene section identifier, reading of the recording data of the broadcast program content is started (step S201 in FIG. 26).

  Then, the system controller unit 20 decompresses and decodes the recorded broadcast program content recording data in the reproduction decode output unit 10 and supplies the decompressed decode output to the recording encoding processing unit 3 so as to perform compression encoding again. Control (step S202).

  In parallel with this, the system controller unit 20 refers to the position information of the specific scene section of the additional information file for the read broadcast program content, and monitors the start point of the specific scene section (step S203). If it is not the start point of the section, control is performed so that the encoded recording data is recorded on the recording medium 5 (step S204).

  Then, the system controller unit 20 determines whether or not the recording of the main information by the post-processing of the initially recorded broadcast program content has been completed (step S205). Returning to step S201, the processes after step S201 are repeated.

  Further, when it is determined in step S203 that it is the start point of the specific scene section, the system controller unit 20 temporarily stops reading, decoding, and encoding of the recording data of the broadcast program content that is initially recorded (step S207). Then, the system controller unit 20 jumps the reading position of the recording data from the recording medium 5 from the start point to the end point of the specific scene section (step S208), and temporarily stores the existence position information of the specific scene section (step S209). ). Then, the system controller unit 20 resumes reading, decoding, and encoding of the recording data from the recording medium 5 (Step S210), returns to Step S203, and repeats the processing after Step S203.

  If it is determined in step S205 that recording of the main information of the initially recorded broadcast program content has been completed, the correspondence information between the corresponding position of the specific scene section temporarily stored in step S209 and the corresponding specific scene section identifier is used. The content additional information file is generated, and the generated content additional information file is associated with the broadcast program content identification information and recorded on the recording medium 5 (step S206). Thereafter, the system controller unit 20 performs post-recording processing of information on the specific scene section.

  That is, the system controller unit 20 refers to the additional information file and refers to the specific scene section identifier of the first specific scene section in the initially recorded information signal (step S221 in FIG. 27).

  Then, the system controller unit 20 records the specific scene section identifier of the specific scene section and the specific scene section identifier recorded in the specific scene section management information (specific scene section recording address information file in this example) of the recording medium 5. In comparison with the above, it is checked whether or not the unrecorded specific scene section is information on the specific scene section already recorded in the recording medium 5 as one of the specific scene section information group (step S222). ), It is determined whether or not the check result has been recorded (step S223).

  When it is determined in step S223 that the unrecorded specific scene section has already been recorded, the system controller unit 20 refers to the additional information file and specifies the unrecorded specific scene section. It is determined whether or not there is a scene section (step S229). When it is determined in step S229 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S230). Thereafter, the process returns to step S222, and the processes after step S222 are repeated.

  When it is determined in step S223 that the unrecorded specific scene section is not recorded, the system controller unit 20 sets the read position from the recording medium 5 as the start point of the specific scene section (step S224). The recording data of the specific scene section is read out, the read recording data is decompressed and decoded, the decompressed decoded output is subjected to recording encoding processing, and additionally recorded in the specific scene section group recording area of the recording medium 5 (Step S225).

  Then, the system controller unit 20 refers to the additional information file, monitors the end point of the specific scene section (step S226), and continues step S225 until the end point is reached. When the end point of the specific scene section being recorded is determined in step S226, the system controller unit 20 temporarily stops reading, decoding, and encoding from the recording medium 5 (step S227).

  Then, the system controller unit 20 additionally records the identifier and the recording address of the recorded specific scene section in the specific scene section recording address information file of the recording medium 5 as an example of the specific scene section management information file. The file is updated (step S228). Then, the system controller unit 20 returns to step S229 and determines whether or not there is a specific scene section that has not been re-recorded.

  When it is determined in step S229 that there is no specific unrecorded scene section in the initial recording data of the recording medium 5, the system controller unit 20 ends the recording process on the recording medium 5 that is the first recording medium. The recording end process is performed (step S231), and this recording process routine is ended.

[Constant dubbing in compression dubbing mode]
The dubbing recording in the compression dubbing mode in the fourth embodiment is performed using the recording data after the post-processing. The constant-speed dubbing process in the compression dubbing mode according to the fourth embodiment will be described with reference to the flowcharts of FIGS.

  First, the system controller unit 20 accepts designation of broadcast program content to be dubbed (step S241). At this time, in this example, although not shown, a list of broadcast program contents that can be dubbed recorded on the recording medium 5 is displayed on the display screen of the display unit 24, and the broadcast program content of the display screen is displayed. From the list, designation of broadcast program content to be dubbed by the user through the user input interface unit 21 is accepted.

  Next, the system controller unit 20 starts reading the recording data (see FIG. 24B) of the main information of the broadcast program content dubbed from the recording medium 5 (step S242).

  Then, the system controller unit 20 decompresses and decodes the recording data of the main information of the designated broadcast program content in the reproduction decode output unit 10, supplies the decompressed decoded output to the record encoding processing unit 3, and compresses again. Control is performed to encode (step S243). Then, the system controller unit 20 controls to record the encoded main program information data on the external recording medium 7 that is the dubbing destination (step S244).

  Then, the system controller unit 20 determines whether or not the dubbing of the main information of the broadcast program content designated for dubbing has been completed (step S245). If it is determined that the dubbing has not ended, the system controller unit 20 returns to step S242 and returns to step S242. The subsequent processing is repeated.

  If it is determined in step S245 that the dubbing of the main content information of the content designated for dubbing has been completed, the content additional information file for the content designated for dubbing (see FIG. 24B) is stored in the external recording medium 7. Dubbing recording is performed (step S246).

  Next, the system controller unit 20 determines whether there is another content designated for dubbing (step S247). When it is determined that there is another content designated to be dubbed, the system controller unit 20 returns to step S242 and repeats the processing after step S242. That is, when there are a plurality of contents designated for dubbing, only the main information is first dubbed and recorded.

  If it is determined in step S247 that there is no other content designated for dubbing, the system controller unit 20 performs constant-speed dubbing processing of information on the specific scene section. That is, the system controller unit 20 refers to the content additional information file of the content in which the main content information is dubbed and refers to the specific scene section identifier of the first specific scene section in the information signal of the content designated to be dubbed ( Step S251 in FIG. 29).

  Then, the system controller unit 20 recognizes the specific scene section identifier of the specific scene section and the specific scene section already registered in the specific scene section recording address information file which is the specific scene section management information of the external recording medium 7 to be copied. In comparison with the identifier, it is checked whether or not the specific scene section is information on the specific scene section already recorded on the external recording medium 7 (step S252), and the check result has been recorded. Whether or not (step S253).

  When it is determined in step S253 that the specific scene section being referred to has already been recorded, the system controller unit 20 determines whether or not there is a specific scene section that is not referred to in the dubbed information signal. (Step S260). If it is determined in step S260 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S261). Then, the process returns to step S252, and the processes after step S252 are repeated.

  When it is determined in step S253 that the specific scene section being referred to is not already recorded on the external recording medium 7, the system controller unit 20 sets the read position from the recording medium 5 to the start of information on the specific scene section. Set to a point (step S254), the recording data of the specific scene section is read, the read recording data is decompressed, the decompressed decoded output is subjected to recording encoding processing (step S255), and the external recording medium 7 Control is performed so that additional recording is performed in the specific scene section information group recording area (step S256).

  Then, the system controller unit 20 refers to the content additional information file, monitors the end point of the specific scene section (step S257), and continues step S256 until the end point is reached. When the end point of the specific scene section during dubbing recording is determined in step S257, the system controller unit 20 temporarily stops reading, decoding, and encoding of the data of the specific scene section from the recording medium 5 (step S258). .

  Then, the system controller unit 20 records the specific scene section management information in the specific scene section information recording area of the external recording medium 7 as the dubbing destination, that is, the specific scene section recorded in the specific scene section recording address information file in this example. The recording address of the information is additionally recorded, and the specific scene section recording address information file is updated (step S259).

  After that, the system controller unit 20 returns to step S260 and repeats the processing after step S260. When it is determined in step S260 that the unrecorded specific scene section is not present in the duplication source content designated to be dubbed on the recording medium 5, the system controller unit 20 ends the constant-speed dubbing process (step S262). This processing routine ends.

[High-speed dubbing in compressed dubbing mode]
Next, the high-speed dubbing processing operation in the compression dubbing mode according to the fourth embodiment will be described with reference to the flowcharts of FIGS.

  First, the system controller unit 20 accepts designation of broadcast program content to be dubbed (step S261). At this time, in this example, although not shown, a list of broadcast program contents that can be dubbed recorded on the recording medium 5 is displayed on the display screen of the display unit 24, and the broadcast program content of the display screen is displayed. From the list, designation of broadcast program content to be dubbed by the user through the user input interface unit 21 is accepted.

  Next, the system controller unit 20 starts to read out the recording data of the main information of the broadcast program content designated to be dubbed from the recording medium 5 (step S262). During this high-speed dubbing, the recording data is not subjected to decompression decoding and recompression encoding processing, but data dubbing is performed in units of GOP. Therefore, the system controller unit 20 reads out the recording data of the main information from the recording medium 5 in units of GOP. Then, the recording data is supplied to the recording processing unit 4 through the reproduction processing unit 9, and the external recording medium processing unit 6 is controlled to perform dubbing recording on the external recording medium 7 (step S263).

  Next, the system controller unit 20 determines whether or not the dubbing of the main information of the broadcast program content designated for dubbing has been completed (step S264). If it is determined that the dubbing has not ended, the system controller unit 20 returns to step S262, and this step The processes after S262 are repeated.

  When it is determined in step S264 that the dubbing of the main information of the designated broadcast program content has been completed, the system controller unit 20 adds the content additional information file for the content designated for dubbing (see FIG. 24B). Is dubbed and recorded on the external recording medium 7 (step S265).

  Next, the system controller unit 20 determines whether there is another content designated for dubbing (step S266). When it is determined that there is another content designated to be dubbed, the system controller unit 20 returns to step S262 and repeats the processing after step S262. That is, when there are a plurality of contents designated for dubbing, only the main information is first dubbed and recorded.

  If it is determined in step S266 that there is no other content designated for dubbing, the system controller unit 20 performs high-speed dubbing processing of information on the specific scene section. That is, the system controller unit 20 refers to the additional information file and refers to the specific scene section identifier of the first specific scene section in the dubbed information signal (step S271 in FIG. 31).

  Then, the system controller unit 20 recognizes the specific scene section identifier of the specific scene section and the specific scene section already registered in the specific scene section recording address information file which is the specific scene section management information of the external recording medium 7 to be copied. In comparison with the identifier, it is checked whether or not the specific scene section is information on the specific scene section already recorded on the external recording medium 7 (step S272), and the check result has been recorded. Whether or not (step S273).

  If it is determined in step S273 that the specific scene section being referred to has already been recorded, the system controller unit 20 determines whether or not there is a specific scene section that is not referred to in the dubbed information signal. (Step S279). When it is determined in step S279 that there is an unrecorded specific scene section, the system controller unit 20 refers to the specific scene section identifier of the next specific scene section in the additional information file (step S280). Then, the process returns to step S272, and the processes after step S272 are repeated.

  When it is determined in step S273 that the specific scene section being referred to has not been recorded on the external recording medium 7, the system controller unit 20 sets the read position from the recording medium 5 to the start of information on the specific scene section. A point is set (step S274), the GOP unit of the recording data of the specific scene section is read, and the read recording data of the GOP unit is additionally recorded in the specific scene section information group recording area of the external recording medium 7. Control is performed as described above (step S275).

  Then, the system controller unit 20 refers to the content additional information file, monitors the end point of the specific scene section (step S276), and continues step S275 until the end point is reached. When the end point of the specific scene section during dubbing recording is determined in step S276, the system controller unit 20 temporarily stops reading the data of the specific scene section from the recording medium 5 (step S277).

  Then, the system controller unit 20 records the specific scene section management information in the specific scene section information recording area of the external recording medium 7 as the dubbing destination, that is, the specific scene section recorded in the specific scene section recording address information file in this example. The recording address of the information is additionally recorded, and the specific scene section recording address information file is updated (step S278).

  Thereafter, the system controller unit 20 returns to step S279, and repeats the processing after step S279. When it is determined in step S279 that there are no unrecorded specific scene sections in the copy source content designated to be dubbed on the recording medium 5, the system controller unit 20 ends the high-speed dubbing process (step S281). The processing routine ends.

  In the description of the fourth embodiment described above, in the post-processing in recording on the first recording medium, the recorded data that was initially recorded is decoded and re-encoded to separate the main story information and the specific scene section information. However, similarly to the high-speed dubbing in the compression dubbing mode of the first to third embodiments described above, the initially recorded recording data can be recorded at high speed in a compressed state in units of GOP. .

  In the above description of the fourth embodiment, in the post-processing in recording on the first recording medium, the information of the specific scene section is recorded as only one with the same specific scene section identifier. However, in the post-processing, the specific scene sections are simply recorded in the extraction order, and when the information of the specific scene sections is dubbed and recorded, only one with the same specific scene section identifier is recorded. You may do it.

[Fifth Embodiment]
In the above-described embodiment, since the data amount of the copy source recording data and the free capacity of the copy destination recording medium are not considered at the time of dubbing, the dubbing of the copy source recording data is performed when the free space is small. May fail. The fifth embodiment is an example in which this point is improved and dubbing is performed.

  FIG. 32 is a block diagram of a hardware configuration example of the recording / reproducing apparatus in the case of the fifth embodiment. 32 is different from the block diagram of the hardware configuration example of the recording / reproducing apparatus of the first to fourth embodiments shown in FIG. 1 in that the dubbing recording data amount calculating unit 26 includes the system controller unit 20. The other points are the same except that they are connected to each other. The dubbing recording data amount calculation unit 26 can be configured by performing software processing using a software program of the system controller unit 20.

  The software program for the dubbing process in the system controller unit 20 can use the dubbing execution process described in the above first to fourth as the dubbing execution process itself. However, in the fifth embodiment, the dubbing user interface process before the start of the dubbing process is different from the other embodiments.

  The dubbing user interface processing in the fifth embodiment will be described below with reference to the flowcharts of FIGS. 33 to 35 and FIGS. 36 and 37 which are examples of the dubbing user interface screen. The dubbing user interface screens shown in FIGS. 36 and 37 are generated by the dubbing user interface generation unit 25.

  When the user performs a dubbing request operation through the user input interface unit 21, the system controller unit 20 displays a dubbing operation screen (step S291). The dubbing operation screen displays a list of dubbing source broadcast program contents recorded on the first recording medium of the duplication source, for example, the recording medium 5, and the user desires to dubb from the list. The content to be selected can be specified. The dubbing operation screen also displays an inquiry as to whether simple dubbing or compression dubbing is desired, and accepts selection designation from the user.

  The system controller unit 20 receives a dubbing mode selection designation from the user (step S292), and determines whether simple dubbing or compression dubbing is selected (step S293).

  When it is determined in step S293 that simple dubbing has been selected, the system controller unit 20 first accepts selection designation of content to be dubbed (step S294). Then, the system controller unit 20 uses the dubbing recording data amount calculation unit 26 to calculate the data amount MA of the dubbing source broadcast program content and the free space MB of the dubbing destination recording medium, for example, the external recording medium 7 (step S295). ).

  Then, the system controller unit 20 determines whether or not the designated broadcast program content can be simply dubbed (step S296). If it is determined in step S296 that the data amount MA ≦ the free capacity MB and simple dubbing is possible, the system controller unit 20 notifies the display screen of the display unit 24 that simple dubbing is possible. An operation screen is displayed (step S297). On this operation screen, operation icons such as “execute dubbing” and “cancel” are displayed.

  The system controller 20 determines whether or not a dubbing execution instruction has been given by operating the “dubbing execution” icon on the operation screen (step S298), and when it is determined that a dubbing execution instruction has been issued, simple dubbing is performed. (Step S299), and after dubbing is completed, the dubbing user interface process is terminated.

  If it is determined in step S298 that a dubbing execution instruction has not been issued, the system controller unit 20 determines whether or not a dubbing stop instruction has been made by operating the “stop” icon (step S300). If it is determined that no instruction has been given, the process returns to step S294, and a change in the broadcast program content to be dubbed is accepted. If it is determined in step S300 that a cancel instruction has been issued, the dubbing user interface process is terminated.

  If it is determined in step S296 that the data amount MA> the free capacity MB and simple dubbing is not possible, the system controller unit 20 determines that “Simple dubbing is not possible, so whether to shift to the compression dubbing mode? The inquiry message ”is displayed on the display screen (step S311 in FIG. 34).

  Then, the system controller unit 20 receives a user's reply operation to the inquiry message, and determines whether or not to shift to the compressed dubbing mode (step S312). If it is determined in step S312 that the mode does not shift to the compression dubbing mode, the system controller unit 20 returns to step S300 in FIG. 33 to determine whether or not a dubbing stop instruction has been issued, and the above-described determination is made according to the determination result. Perform processing.

  When it is determined in step S312 that the mode is shifted to the compression dubbing mode, the system controller unit 20 accepts selection designation of content to be dubbed (step S313). Then, the system controller unit 20 uses the dubbing recording data amount calculation unit 26 to compress the entire program data amount MC of the broadcast program content after compression dubbing, and the data amount MD after compression dubbing only of the main program information excluding information on the specific scene section The free capacity MB of the external recording medium 7 that is the recording medium of the dubbing destination in this example is calculated (step S314).

  Then, the system controller unit 20 determines whether or not compression dubbing of the full-length data of the designated broadcast program content is possible (step S315). If it is determined in step S315 that the data amount MC ≦ the free space MB and the full-length data of the designated broadcast program content can be compressed and dubbed, the system controller unit 20 displays on the display screen of the display unit 24, An operation screen for notifying that compression dubbing of the full-length data of the designated broadcast program content is possible is displayed (step S316). On this operation screen, operation icons such as “execute dubbing” and “cancel” are displayed.

  The system controller unit 20 determines whether or not a dubbing execution instruction has been made by operating the “dubbing execution” icon on the operation screen (step S317). Such compression dubbing is executed (step S318), and after dubbing is completed, the dubbing user interface process is terminated.

  If it is determined in step S317 that a dubbing execution instruction has not been issued, the system controller unit 20 determines whether or not a “stop” icon has been operated to give a dubbing stop instruction (step S319). If it is determined that no instruction has been given, the process returns to step S313 to accept a change in the broadcast program content to be dubbed. If it is determined in step S319 that a cancel instruction has been issued, the dubbing user interface process is terminated.

  If it is determined in step S315 that the data amount MC> the free space MB and the full data of the designated broadcast program content cannot be compressed, the system controller unit 20 performs the compression dubbing only of the main information. The subsequent data amount MD is compared with the free space MB, and it is determined whether or not compression dubbing is possible if only the main information is present (step S321 in FIG. 35).

  If it is determined in step S321 that compression dubbing is possible only with the main content information, “compression dubbing is executed because the content designated for dubbing can be compressed dubbing only with the main content information. Is displayed on the display screen (step S322). On this display screen, operation icons such as “execute dubbing” and “cancel” are displayed.

  The system controller 20 determines whether or not a dubbing execution instruction has been made by operating the “dubbing execution” icon on the display screen (step S323). Compressed dubbing is executed (step S324), and after dubbing is completed, the dubbing user interface process is terminated.

  If it is determined in step S324 that a dubbing execution instruction has not been issued, the system controller unit 20 determines whether or not a dubbing stop instruction has been made by operating the “stop” icon (step S326). If it is determined that no instruction has been given, the process returns to step S313 in FIG. 34 to accept a change in broadcast program content to be compressed dubbed. If it is determined in step S326 that a cancel instruction has been issued, the dubbing user interface process is terminated.

  If it is determined in step S321 that the data amount MD after compression dubbing of only the main information is larger than the free space MB, and the compression dubbing of only the main information of the designated broadcast program content is not possible, the system controller unit 20 displays on the display screen that compression dubbing is not possible (step S325), proceeds to step S326, and performs the processing after step S326.

  Examples of display screens in the compressed dubbing mode are shown in FIGS. FIG. 36 is a first example. FIG. 36A shows an example of the display screen in step S316, and shows the content for which dubbed content is designated in the list 31 of broadcast program content to be dubbed.

  A cylindrical figure 32 shows a hard disk as a first recording medium (replication source) in this example, and a double ellipse figure 33 shows a DVD as a second recording medium (replication destination) in this example. Is shown. The pie chart 34 shows the relationship between the data amount of the copy-designated content and the free capacity of the copy destination recording medium. The portion indicated by this indicates the data amount of information of the specific scene section.

  Reference numerals 35 to 37 denote icons such as “execute (dubbing)” and “cancel” described above.

  FIG. 36 (A) shows a state where, when compression dubbing is performed, the data amount MC after compression dubbing of the entire content of the dubbed content is smaller than the free capacity Mb, and compression compression dubbing of the entire content is possible. .

  In FIG. 36B, since dubbing-designated content is added, full-length dubbing of the plurality of contents cannot be performed because there is not enough free space, but if only dubbing-designated content main information is provided, It shows that compression dubbing is possible. In FIG. 36B, when the user operates the “execute” icon 35, compression dubbing is executed.

  FIG. 37 is a second example of a display screen in the compressed dubbing mode. The difference from the first example of FIG. 36 is that the graphic showing the relationship between the data amount of the copy-designated content and the free capacity of the copy destination recording medium has been changed from a pie chart 34 to a bar graph 38. It is. Others are exactly the same as in FIG.

[Sixth Embodiment]
The sixth embodiment is a development of the embodiment of FIG. In the sixth embodiment, when dubbing content is specified, the main information and the specific scene section can be specified in detail so that fine dubbing can be specified.

  The hardware configuration of the recording / reproducing apparatus of the sixth embodiment is the same as that shown in FIG. 32, and the dubbing user interface screens of FIGS. 38 to 40 are generated by the dubbing user interface generation unit 25. Is.

  In the sixth embodiment, for example, as shown in FIG. 38, the data amount of the copy source (data amount after compression dubbing) is displayed in the copy source data amount display column 41, and is stored in the copy destination recording medium. The free space is displayed in the copy destination free space display field 42.

  That is, in the dubbing pre-execution process of the sixth embodiment, the dubbing data amount calculator 26 calculates the data amount of the designated dubbing source information signal and the free space of the dubbing destination recording medium. The calculation result is reflected on the dubbing operation screen.

  In the example of FIG. 38A, the data amount of the copy source of the content to be dubbed selected and specified in the list 31 is “5 gigabytes”, which is larger than the free capacity “4.7 gigabytes”. This indicates that dubbing is not possible. As shown in FIG. 38, in the sixth embodiment, a “detailed setting” icon 39 is displayed as an icon, and dubbing can be specified in more detail.

  When the “detailed setting” icon 39 is operated, as shown in FIG. 38B, the content list is divided into main content information and information other than the main information (information on specific scene sections). To be selectable. The user can separately specify dubbing for main content information and other than main information for each content.

  In the example of FIG. 38, dubbing of the entire contents 1 and 2 is not possible as shown in FIG. 38 (A), but detailed settings are made and only the main contents 1 and 2 are copied. FIG. 38 (B) shows that compression dubbing has become possible.

  FIG. 39 shows another display example in the sixth embodiment. In the example of FIG. 39, as shown in FIG. 39 (B), when each content is selected, more than a plurality of main information and a plurality of main information are displayed in the display column 310 for each content. The main information and the information other than the main information can be finely designated for dubbing.

  FIG. 40 shows still another display example in the sixth embodiment. In the example of FIG. 40, as shown in FIG. 40 (B), each content is divided into two parts other than the main part information and the main part. Each content is displayed in more detail divided into a plurality of main information and a plurality of main information other than the main information, and the dubbing designation can be made in detail for each of the main information and other than the main information.

  In the sixth embodiment, the processing operation of simple dubbing is exactly the same as in the fifth embodiment, and therefore the flowchart of FIG. 33 can be applied in the same manner in the sixth embodiment. In the sixth embodiment, processing shown in the flowcharts of FIGS. 41 to 43 is performed instead of the processing of the flowcharts of FIGS. 34 to 35 in the fifth embodiment.

  That is, in FIG. 41, steps S311 to S319 are exactly the same as steps S311 to S319 in the flowchart of FIG. 34, and thus are given the same step numbers.

  In the sixth embodiment, when it is determined in step S315 that the specified content cannot be fully dubbed in the compressed dubbing mode, the system controller unit 20 operates the “detail setting” icon 37 by the user. It is determined whether or not it has been done (step S331).

  If it is determined in step S331 that the “detailed setting” icon 37 has not been operated, the system controller unit 20 proceeds to step S321 in FIG. 42, and if it is determined that the “detailed setting” icon 37 has been operated. Then, the process proceeds to step S351 in FIG.

  In FIG. 42, steps S321 to S325 are exactly the same as steps S321 to S325 in the flowchart of FIG.

  In the sixth embodiment, in FIG. 42, when the system controller unit 20 determines in step S321 that compression dubbing is impossible even with only the main information, the compression dubbing is performed in step S325. Impossibility is displayed and the user is notified, and then the user input is waited (step S341).

  When a user input is accepted in step S341, the system controller unit 20 determines whether or not the user input is a designation change operation for content to be dubbed (step S342). If it is determined in step S342 that the operation is a designation change operation for content to be dubbed, the system controller unit 20 returns to step S313 in FIG.

  If it is determined in step S342 that the operation is not a specification change operation for the content to be dubbed, the system controller unit 20 determines whether or not an instruction operation for content detail setting has been performed by the user operating the “detail setting” icon 37. (Step S343).

  If it is determined in step S343 that the “detailed setting” icon 37 has not been operated, the system controller unit 20 determines whether or not the “stop” icon 36 has been operated to instruct the dubbing stop (step S344). ), When it is determined that no stop instruction has been issued, the process returns to step S341 to wait for user input. If it is determined in step S344 that a cancel instruction has been issued, the dubbing user interface process is terminated.

  If it is determined in step S343 that the “detailed setting” icon 37 has been operated, the system controller unit 20 proceeds to step S351 in FIG.

  In step S351 in FIG. 43, the system controller unit 20 converts the content designated for dubbing into the main content information, as shown in FIG. 38 (B), FIG. 39 (B), and FIG. 40 (B). A detailed list is displayed on the display screen separately from the main information (information of a specific scene section).

  Then, the system controller unit 20 determines whether or not detailed dubbing designation from the user has been received for the main information and information other than the main information (specific scene section information) (step S352). When it is determined that the designation has not been accepted, it is determined whether or not the “stop” icon 36 has been operated to give a dubbing stop instruction (step S353). When it is determined that no stop instruction has been issued, the process proceeds to step S352. Return and wait for detailed dubbing designation. If it is determined in step S353 that a cancel instruction has been issued, the dubbing user interface process is terminated.

  If it is determined in step S352 that the detailed dubbing designation has been received, the system controller unit 20 uses the dubbing recording data amount calculation unit 26 to calculate the data amount ME after compression dubbing of the detailed dubbing designated information. (Step S354), the data amount ME is compared with the free space MB of the copy destination recording medium to determine whether or not dubbing is possible (Step S355).

  Then, as shown in FIGS. 38 to 40, the system controller unit 20 displays the data amount ME and the free space MB in the display column 41 and the display column 42, and determines that dubbing is not possible in step S355. If so, a message indicating that dubbing is not possible is displayed on the display screen (step S356), and the process returns to step S352.

  If it is determined in step S355 that dubbing is possible, the system controller 20 displays a message indicating that dubbing is possible (step S357), and waits for a dubbing execution instruction from the user (step S357). S358) When it is determined that the “execution” icon 35 has been operated to give an instruction for execution by the user, the compression dubbing process is executed (step S359). And after this compression dubbing process is complete | finished, this process routine is complete | finished.

  If it is determined in step S358 that a dubbing execution instruction has not been issued, the system controller unit 20 returns to step S352 and repeats the processing from step S352 onward.

[Seventh Embodiment]
In the first to fourth embodiments described above, when the broadcast program content is dubbed and recorded in the compressed dubbing mode, it is separated into information of only the main information and information of a specific scene section. In the fifth embodiment, when the free space is smaller than the amount of information data to be copied, all the specific scene sections are deleted and only the main information is dubbed.

  For this reason, as the information signal of the broadcast program content after dubbing recording, for example, all CM sections other than the main part of the program are deleted, which is disadvantageous for the CM providing side. When the insertion of the CM section is used as an effect, there is a problem that the attractiveness of the program content is impaired.

  For example, by broadcasting the answer after the CM section in a quiz program, inserting the CM section at the beginning of the excitement can produce an effect that pulls the viewer's feelings, or creates an exhilarating feeling In such a case, if all the commercial sections are cut and the main part of the program is connected, the production effect cannot be obtained and the program becomes less attractive.

  Also, in some broadcast programs, after insertion of a CM section, there is a case where the same scene is replayed so as to be broadcast again by going back about a few seconds (rollback). If all the CM sections are cut using the function of Patent Document 1, there is a problem that the same scene is simply continued for several seconds in the rollback portion.

  In view of this problem, the seventh embodiment reduces the disadvantages for the CM providing side, and also reduces the attractiveness of the program content when the broadcast program uses the insertion of the CM section as an effect. The purpose is to prevent it from being lost.

  That is, in the seventh embodiment, after the dubbing recording in the compressed dubbing mode, at least one specific scene section is left in the section before or after the main information. Also in the seventh embodiment, the information on the specific scene section is recorded separately so that only one of the same specific scene section identifiers is recorded, and the location of each specific scene section is recorded. And a duplicate additional information file including the corresponding data with the corresponding specific scene section identifier and the recording address information of the information of each specific scene section.

  FIG. 44 is a diagram for explaining an example of the seventh embodiment, and is an example in which the seventh embodiment is applied to the first embodiment.

  FIG. 44B shows an example of recording data after performing compression dubbing according to the seventh embodiment. In the case of the seventh embodiment, after compression dubbing to the copy destination recording medium, as shown in FIG. 44B, one specific scene section is left before or after the main information. To do.

  In this example, after the recording information signal including the main information recorded with the one specific scene section being recorded, the information of the specific scene section inserted in the content is the same specific scene section identifier. Only one is recorded on the copy destination recording medium.

  Then, duplication recording is performed on the duplication additional information file including the correspondence information between the position of the specific scene section not inserted before or after the main information, the specific scene section identifier, and the recording address information of the information of the specific scene section. The information is recorded on the copy destination recording medium in association with the recorded information. In the duplicate additional information file, the existence information of the specific scene section inserted before or after the main information may be recorded together with the flag already inserted into the main information. In this case, at the time of reproduction, only the specific scene section in which the inserted flag does not exist is inserted between the main part information based on the existence position information.

  In the seventh embodiment, in the fifth embodiment, when dubbing of the entire content designated for dubbing is impossible, the data when the information of the specific scene section recorded together is not recorded. The amount of data, that is, the amount of data in which one specific scene section is inserted before or after the main information is compared with the free space, and dubbing recording is performed to the user when the free space is smaller Whether or not, and after obtaining the user's approval confirmation, the compression dubbing is executed.

  According to the seventh embodiment, even after compression dubbing recording, at least one specific scene section remains between the main information and the main information, so that the above-described problems can be avoided. Can do.

  In the case where a plurality of specific scene sections exist continuously before or after the main information, at least one specific scene section to be left before or after the main information is defined as (1) any one And (2) a method of referring to the additional information file recorded on the first recording medium and leaving a specific scene section having an identifier that is as different as possible for the entire content. The example of FIG. 44 is the latter case (2).

  Although the detailed description is omitted, the seventh embodiment is an embodiment corresponding to the combination of the second embodiment and the fifth embodiment, and the third embodiment and the fifth embodiment. The present invention can be similarly applied to the embodiment corresponding to the combination and the embodiment corresponding to the combination of the fourth embodiment and the fifth embodiment.
