Description

  The present invention relates to a plurality of programs (continuous programs) of the same system from various programs recorded on a large-capacity recording medium as a series of programs, and divides them into a plurality of smaller-capacity recording media. The present invention relates to a recording / reproducing apparatus capable of performing the above.

  In recent years, as disclosed in, for example, Patent Document 1, a hard disk drive and a DVD drive are provided, and an analog video / audio signal from an analog tuner is encoded by an MPEG encoder using an MPEG-PS (MPEG Program Stream) system (hereinafter referred to as an MPEG video stream). A hybrid recorder capable of digitally recording MPEG-encoded video / audio data on a removable recording medium such as a hard disk or a DVD-R has been developed.

  In the hybrid recorder, the encoding bit rate can be arbitrarily set within the range that can be recorded on the recording medium during MPEG encoding, and the higher the encoding bit rate, the higher the recording quality and the higher the sound quality are.

  In such a hybrid recorder, since the capacity of the hard disk is much larger and faster than the recordable capacity of one DVD-R, the broadcast program being received is recorded on the hard disk. Data is copied from a hard disk to a DVD-R medium and copied (hereinafter referred to as dubbing).

For example, there are two types of dubbing methods disclosed in Patent Document 1. Hereinafter, description will be made using the reference numerals in FIG.
In the first dubbing method, MPEG encoded video / audio data recorded on the hard disk B is sequentially reproduced by the demodulator 6 of the hard disk B. At that time, the demodulating unit 6 of the hard disk B and the modulating unit 3 of the optical disc A are connected via the third switching unit 15 and the second switching unit 14, and the reproduced video / audio data is the modulating unit of the optical disc A. 3 is copied to the disk DS of the optical disk A as it is to realize dubbing.

  In the first dubbing method, digital data is simply transferred and copied, and dubbing can be realized at a data transfer rate allowed by the demodulating unit 6, the modulating unit 14, the hard disk HD, and the optical disc DS. Is possible. In recent years, products that can be dubbed at 8 times speed have been released. Since dubbing by this method is merely data copying, the data amount of the program when it is recorded on the hard disk HD is not changed even when dubbing to the optical disk, and the image quality / sound quality is not changed at all.

In the second dubbing method, the signal output from the demodulating unit 6 is once MPEG-decoded by the video / audio expansion unit 16 and then the video / audio compression unit 13 via the first switching unit 12. MPEG encoding is performed again at the bit rate, and dubbing is realized by recording on the optical disc DS by the modulation unit 3 via the second switching unit 14. In this second dubbing method, since MPEG decoding is performed once and MPEG encoding is performed again, the dubbing speed is governed by the real time of the program to be dubbed, and a dubbing time of one hour is required for a one-hour program. However, the bit rate for recording on the optical disc can be different from the bit rate recorded on the hard disk, and there is an advantage that the data amount of the program at the time of re-recording can be changed.
When the first and second dubbing methods are arranged, the first dubbing method enables dubbing to a DVD-R while maintaining the same bit rate, that is, maintaining the same image quality and sound quality. In this case, high-speed dubbing (hereinafter referred to as high-speed dubbing) is possible within the ranges allowed by the data reading speed from the hard disk, the data transfer speed to the DVD drive, and the writing speed to the DVD-R. It is. In this case, the data amount of the program recorded on the hard disk is naturally the same as the data amount copied on the DVD.

  In the second dubbing method, a decoded signal obtained by decoding the video / audio data once reproduced from the hard disk by the MPEG decoder (hereinafter referred to as MPEG decoding) is input to the MPEG encoder, and the bit rate recorded on the hard disk After MPEG encoding again at a different bit rate, the video / audio data can be recorded on a DVD-R. In this case, the data amount of the program recorded on the hard disk is different from the data amount copied on the DVD, and this method is used when the disk capacity is not enough to accommodate multiple times of the program. By dubbing with a reduced amount of data, there is an advantage that a desired number of programs can be recorded.

By the way, when copying a program or the like recorded on a hard disk to a disk such as a DVD-R, it is common to collect and copy programs of the same system on the same disk in order to facilitate later classification and organization. It is. For example, it is more convenient to record a specific series of series, such as “Mito Komon” or “Nodojiman”, which are broadcast every week, on separate disks. However, since the number of programs (data capacity) that can be stored on one disk is limited, it is difficult to put a large number of programs in a series into one, and of course, copying is divided into a plurality of sheets.
Prior to the start of dubbing, the user individually considers which of the first and second methods should be selected for each program to be dubbed, and then performs dubbing. In the case of the first method, a series of programs desired by the user is searched and extracted from the recorded program list, and the number of programs that can be included in one disc depends on the capacity and number of DVD-Rs used for dubbing. However, since the user must manually group the extracted programs while considering the combination of programs and the like, dubbing must be started.

  Also, if the desired number of programs does not fit on one DVD-R, MPEG decoding is performed once by the second dubbing method, then the bit rate is changed, MPEG encoding is performed again, and recording is performed on the DVD-R. There is a problem that the user has to perform the task of performing the operation, and the operation is complicated and troublesome.

JP-A-2004-127470 “Dubbing Device and Control Method Therefor”

  Since the conventional recording / reproducing apparatus is configured as described above, a series of related programs once recorded on a hard disk or the like are to be dubbed from the hard disk to a plurality of DVD-Rs or the like. However, there is a problem that the operation is complicated and troublesome.

  Also, if the number of programs in one DVD-R cannot be set well, the user must perform the work of MPEG decoding, changing the bit rate, MPEG encoding again, and recording to the DVD-R. There was a problem that operation was complicated and difficult.

  The present invention has been made to solve the above problems, and does not require a complicated operation by a user, and a series of related programs recorded on a hard disk can be recorded on a plurality of removable media such as a DVD-R. It is an object of the present invention to provide a recording / reproducing apparatus that can easily perform dubbing divided into media.

The recording / reproducing apparatus according to the present invention provides a plurality of program data including video / audio data obtained by receiving a video / audio broadcast, together with a recording date and time, a recording day of the week, a broadcast channel number, and a data amount of each program. First recording and reproducing means for recording and reproducing on a recording medium;
A series of related program data is extracted from a plurality of program data recorded on the first recording medium based on at least one of the recording date and time, the recording day of the week, and the broadcast channel number, and the extracted program Association means for adding the same dubbing ID to each of the data;
Classifying means for classifying the plurality of program data to which the same dubbing ID is added into a plurality of groups in which the total data amount of one group is equal to or less than a specified predetermined data amount;
A second recording / reproducing means for recording and reproducing the plurality of groups of program data on the second removable recording medium having the predetermined capacity is provided.

  Since the present invention is configured as described above, it can be arbitrarily selected from a plurality of types of continuous programs such as a series of continuous dramas recorded temporarily in a fixed recording medium such as a hard disk in advance. When extracting only continuous programs and dividing them into a plurality of removable recording media, a series of programs are automatically extracted, and the series of programs is further recorded to the recording capacity and the number and capacity of removable recording media. Accordingly, the programs are classified into a plurality of program groups and can be sequentially dubbed onto a removable recording medium, so that a series of programs can be stored in a predetermined number of removable recording media without a complicated operation by a person.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the recording / reproducing apparatus of the present invention. In the figure, a tuner 101 selects a desired channel from a video / audio broadcast wave received by an antenna. The output signal of the tuner 101 is input via the changeover switch 102 to encoding means 103 that MPEG-encodes the program video / audio output from the tuner 101 into video / audio data. The output of the encoding means 103 is input to a three-terminal matrix switch 104 whose input / output can be freely switched. The matrix switch 104 is connected to a second recording / reproducing unit 105 that records and reproduces the output of the encoding unit 103 on a recording medium 106 (which is described here as a DVD-R, but is not limited thereto). It is also connected to a first recording / reproducing means 110 that records and reproduces the output of the encoding means 103 from the matrix switch 104 to the hard disk 107. The hard disk 107 is a first recording medium, and the DVD-R 106 is a detachable second recording medium whose capacity is known in advance.

  The MPEG encoded video / audio data of the first and second recording / playback means 105 and 110 are input via the matrix switch 104 to the decoding means 111 for MPEG decoding these signals into analog video / audio signals. The reserved recording control means 115 controls the entire reserved recording when the program is reserved for recording based on the time information of the clock 113. The associating means 108 gives a dubbing ID to related programs based on the information from the reserved recording control means 115. The classifying unit 109 classifies the n (n is a natural number) plural programs associated by the dubbing ID into m (m is a natural number of n or less). In addition, a user IF 150 connected to a push button (not shown) for a user (not shown) to perform various setting operations is provided.

FIG. 7 shows the detailed configuration of the association unit 108 and the classification unit 109. The description of FIG. 7 will be described later.
Next, the operation of the recording / reproducing apparatus shown in FIGS. 1 and 7 will be described. For convenience of explanation, the video / audio data is also referred to as program data.
First, the operation during recording will be described. When the user makes a recording reservation via the user IF 150, the reservation recording control unit 115 generates a reservation recording list 301 as shown in FIG. Among the contents of the scheduled recording list 301 generated by the scheduled recording control unit 115, what can be input by the user is, for example, a recording date (meaning recording start time), day of the week, channel, start / end time, title, and genre. . As shown in FIG. 7, the associating unit 108 includes a dubbing ID adding unit 108a, a recording day determining unit 108b, a recording start time determining unit 108c, a channel determining unit 108d, and a title determining unit 108e. The recording day determination unit 108b, the recording start time determination unit 108c, the channel determination unit 108d, and the title determination unit 108e include items such as the day of the week, the channel, the start / end time, and the title in the reserved recording list 301 or FIG. It is determined whether there is a matching program in the recorded list 302 shown in FIG. 3, and based on the determination result, the dubbing ID adding unit 108a adds the dubbing ID of the same number to all the recording reservations that match. In addition, the meaning of the column described as “capacity” in each diagram such as FIG. 2 indicates “the size of data, that is, the amount of data”.

  The amount of data can be automatically calculated by converting from the start / end time difference. In FIG. 2, there is a program whose recording start time, day of the week, and channel match in the recorded program list 302 for the first program in the reserved recording list 301, and “001” is added as the dubbing ID. In this case, “001” is added. When the recording start time comes, the changeover switch 102 switches to the tuner 101 side based on the command of the reserved recording control means 115, and the encoding means 103 MPEG encodes the analog video / audio signal of the desired program selected by the tuner 101. To start. The matrix switch 104 connects the encoding means 103 and the first recording / reproducing means 110, and the video / audio data of the desired MPEG-encoded program is recorded on the hard disk 107 by the first recording / reproducing means 110. . At that time, the reserved recording information of the recorded program is added to the recorded program list 302 as it is as shown in FIG. In the figure, a case is shown in which a program that has been reserved and recorded on September 19 (Monday) is added as the 29th program in the recorded program list 302.

Details of the operation when adding the dubbing ID in the associating means 108 will be described in detail using a flowchart. FIG. 4 is a flowchart of an operation for adding a dubbing ID. In step S200, the recording day determination unit 108b determines whether there is a program in the reserved recording list 301 or the recorded program list 302 that matches the recording day of the newly reserved program. If there is a matching program, the process proceeds to step S201, and if not, the process ends.
In step S201, the recording start time determination unit 108c determines whether there is a program whose recording start time matches the recording start time of the newly reserved program within a certain range (for example, within two hours) among the programs whose recording days match. If there is a program within the range, the process proceeds to step S202.

In step S202, the channel discriminating unit 108d discriminates that if there is a program whose recording channel matches the channel of the newly reserved program among the programs within the range in step S201, the channel discriminating unit 108d determines that the program is a series of programs. If not, it is determined that there is no series of programs, and the process is terminated.
In step S203, the dubbing ID adding unit 108a determines whether or not a dubbing ID has already been added to the program determined to be a series of programs in the processing up to step S202, and if it has been added, proceeds to step S204. After adding the same dubbing ID to the newly reserved program, the process is terminated. If not, the process moves to step S205, a new ID is added to both, and the process ends.

Next, an operation for performing dubbing will be described.
At the time of dubbing, the dubbing program list generation unit 109a of the classifying unit 109 extracts programs to which the same dubbing ID is added and generates a dubbing program list 303 shown in FIG. FIG. 5 shows an example in which a program with an ID of 001 is extracted. Further, the disc distribution determining unit 109b selects the extracted program according to the number m of discs used for dubbing (m is a natural number and will be described here as being input by a person). Classification is automatically performed as in 304b and 304c (in this example, m = 3).

  For example, the capacity of a DVD-R disc is generally 4.7 Gbytes (gigabytes) at the time of filing of the present application, but it is assumed that the user has set in advance to use three discs. Specifically, an input column for “desired number of used sheets” is displayed in the dubbing program list screen of FIG. 5, and the user inputs the desired number of sheets here. As for the data amount of each program, the bit rate adopted as a standard recording mode for DVD recorders released in recent years is about 5 Mbps (megabits per second), and the recording capacity per hour is about 2 Gbytes. It becomes. Each program of FIG. 5 is also an hour program and is 2 Gbytes. Under this condition, the dubbing division list 304 in FIG. 6 considers that the program groups are classified into three so that the capacity per program group (total programs accommodated on one disc) does not exceed 4.7 Gbytes. As shown in FIG. 6, it is only necessary to classify into three program groups of two programs in order from the program with the oldest recording date.

  In this way, up to three discs are inserted sequentially, and dubbing of program groups with classification numbers 1, 2, and 3 is performed. First, when the first disc is inserted, dubbing of the program group of classification number 1 is started. In the case of FIG. 6, since the capacity of one disk is larger than the data amount of the program group recorded per disk, high speed by data copying from the hard disk 107 to the DVD-R 106 (the above-mentioned first dubbing method). Dubbing is possible. When dubbing is completed, a message prompting the user to replace the disc is displayed. When the user inserts the second disc, dubbing of the program group with classification number 2 is started. Thereafter, all program groups are dubbed in the same manner.

Embodiment 2. FIG.
Some hybrid recorders have a function of obtaining an electronic program guide (EPG = Electric Program Guide) (not shown, but referred to as an electronic program guide receiving device). Information related to the program obtained from the EPG includes the “program name” and “genre” of the program. In the first embodiment, these are described as being input by the user. However, information obtained from these EPGs is used as information for extracting and associating a series of programs from programs that have been reserved-recorded instead of being input by humans. Also good.
FIG. 8 is a block diagram showing the configuration of the recording / reproducing apparatus of the second embodiment. The same reference numerals in the figure as those in FIGS. 1 and 7 of the first embodiment denote the same or corresponding parts, and the detailed description thereof will be omitted. In the figure, an EPG acquisition means 114 for acquiring EPG (Electric Program Guide) information transmitted by being superimposed on a video / audio signal is connected to the reserved recording control means 115. The scheduled recording control means 115 controls the entire scheduled recording when the program is scheduled to be recorded based on the time information of the clock 113 and the EPG acquired by the EPG acquisition means 114.

  Since the recording operation at the time of recording is the same as that in the first embodiment, the description thereof is omitted. In the second embodiment, details of the operation when the association unit 108 adds the dubbing ID will be described in detail with reference to a flowchart.

  In FIG. 9, steps S200 to S202 are the same as those in FIG. In step S202, the channel determination unit 108d determines whether there is a program whose channel matches the channel of the newly reserved program. If there is a match, the process proceeds to step S210, and the title determination unit 108e It is determined whether or not there is a match in part (for example, five characters from the beginning) or all of the title names acquired in (1). If there is a matching program, the process proceeds to step S211, and if not, the process ends. In step S211, the genre discriminating unit 108f determines whether there is a program that matches the genre name acquired in the same EPG (the number of discriminating characters is the same as the title name), and if there is a matching program, moves to step S203. If not, the process is terminated. Further, the processing after step S203 is the same as that in the case of FIG.

  In this way, it is possible to extract a series of related programs using information obtained from the EPG, and to extract programs with higher accuracy. Note that the processing when the extracted programs are classified into a plurality of program groups and dubbed to a plurality of discs is the same as that in the first embodiment, and a description thereof will be omitted.

Embodiment 3 FIG.
In the first embodiment, the case where a program is recorded at a standard mode bit rate of about 5 Mbps on both the hard disk and the DVD-R has been described. However, from the capacity and number of DVD-R disks to be used, the number of assumed series of programs (the number of continuous episodes when taking a drama as an example), and the recording time when the reserved recording is performed for the first time, The bit rate for recording after the second time may be calculated and set. In particular, the broadcast time of a continuous drama is often the same length regardless of the number of episodes, so even if it is set to the same recording time as the first time after the second time, it is not wrong in most cases. This technique is effective.

For example, if the disc of the second recording medium to be used is a 4.7-Gbyte DVD-R, the number of used programs is 3, the number of programs in the series is expected to be 12, and a series of initial programs for which scheduled recording is set Is 1 hour long. In this case, the program length required to be recorded per disc is 12 programs × 1 hour ÷ 3 frames = 4 hours.
Therefore,
4.7 Gbyte / (4 hours × 3600 seconds / hour) × 8 bits (bit) ≈2.6 Mbps
The encoding bit rate at the time of encoding each program is set, and the received broadcast program is recorded on the hard disk 107 at the encoding bit rate. Thereby, at the time of dubbing, the data is copied as it is, so that high-speed dubbing is possible and all the capacity of the disk of the second recording medium can be used effectively. The above calculation is performed by a bit rate rate designation unit (not shown) in the scheduled recording control means 115. In this case, since the “total number of required sheets” is known before the user inputs the desired number of sheets, a numerical value is initially set in the “desired number of used sheets” column described in the description of FIG. 5 of the first embodiment. Is displayed, and if the user approves (presses a decision switch (not shown)), the number is determined.

Embodiment 4 FIG.
In the first embodiment, the number of disks to be used is set by the user. However, the number of disks may be automatically determined from the extracted data amount of each program and the total data amount of the program group.

For example, it is assumed that a program group is extracted as in the dubbing program list 301 in FIG. 5 of the first embodiment, and the disc to be used is a DVD-R having a capacity of 4.7 Gbytes.
The number of programs that can be recorded on a single sheet is obtained by taking the integer part of the value obtained by (capacity of one sheet / data amount of one program). In other words, since 4.7 ÷ 2 = 2.35, if it is classified into two programs, each program enters a disc, and all six programs can be accommodated by using three discs. This calculation is executed by the disk distribution determination unit 109b of the classification unit 109.

Embodiment 5. FIG.
In the first embodiment, the case of performing high-speed dubbing by copying data when dubbing to a disc has been described. However, the total data amount of a program group recorded per disc is larger than the capacity of one disc. In this case, once the program group on the disc is MPEG-decoded and then MPEG-encoded again at an encoding bit rate corresponding to the capacity of the removable recording medium, dubbing can be performed without leaving the capacity of the removable recording medium. There are advantages. That is, all programs scheduled to be dubbed on a disk with insufficient capacity are once MPEG-decoded and MPEG-encoded again.

For example, it is assumed that a program group as shown in the dubbing program list 310 of FIG. 10 is extracted by a previously added dubbing ID (003 in the figure). In this case, since only the last program of No. 41 is 3 Gbytes, if the disc is 4.7 Gbytes, the program group is classified as shown in the dubbing division list 311a, 311b, 311c in FIG. In the third disc, the data amount is 5 Gbytes and cannot fit. Therefore, when dubbing to the first and second discs, high-speed dubbing by copying data is used, and the corresponding 39th, 40th and 41st programs are temporarily MPEG only when dubbing the third disc. Decoding and MPEG encoding are performed again to change the capacity to just fit in one disc. The encoding bit rate in that case is obtained from the capacity of the disc to be used and the sum of the length of the program to be dubbed,
4.7 Gbyte / {(0.5 + 0.5 + 1.5) time × 3600 seconds / hour} × 8 bits≈4.2 Mbps
If so, it is just the amount of data that can fit on one disc. However, the dubbing time takes the sum of the lengths of programs to be dubbed (total time of programs on the dubbing division list), that is, 2.5 hours.

Embodiment 6 FIG.
Also, instead of MPEG decoding and MPEG encoding again for all programs recorded on the disc, only the arbitrary program selected by the user is temporarily MPEG decoded and MPEG encoded again. For other programs, high-speed dubbing may be performed. For example, in the dubbing to the third disc in FIG. 11, the dubbing of the 39th and 40th programs may be dubbed using high-speed dubbing, and the above method may be used only for the dubbing of the 41st program. In this case, the dubbing time can be shortened, but the bit rate of the 41st program will be considerably lower depending on the capacity of the disc and the data volume of the 39th and 40th programs, resulting in poor image quality. There is a possibility. When this method is applied in the case of FIG. 11, the bit rate of the 41st program is
(4.7 Gbyte-2 Gbyte) ÷ (3/2 hours × 3600 seconds / hour) × 8 bits≈4 Mbps
It becomes.

If high-speed dubbing for the 39th and 40th programs can be executed at 8 × speed, the dubbing time is 1 hour ÷ 8 + 1.5 hours = 1.625 hours, which is the same as that in the fifth embodiment. Compared to 5 hours, the increase in dubbing time can be minimized.
Here, the methods of the fifth embodiment and the sixth embodiment have advantages and disadvantages. Which method should be selected may be determined according to the user's preference, but as one method, first, the method of the sixth embodiment is basically adopted, and as a result, one disc is recorded. If the bit rate ratio exceeds 1: 0.7, it will be judged that the quality of one program will be noticeably degraded, and a warning will be displayed (for example, “Image quality of the last program will be significantly degraded”). You may make it do. The user should take this warning and take the method of the fifth embodiment again. In order for the user to specify a program, a number input button (not shown) (referred to as program specifying means) is used.

Embodiment 7 FIG.
The operations from the first embodiment to the sixth embodiment are complicated and difficult operations for some users even though extraction of past recorded programs is almost automated. Therefore, providing a dedicated push button and adding a dubbing ID to the end of the dubbing process can be completed with a single operation of the push button. A desired dubbing operation can be completed only by performing a simple operation without requiring a simple operation.

FIG. 12 is a block diagram showing a schematic configuration of the recording / reproducing apparatus of the present invention. In the figure, a tuner 101 selects a desired channel from radio waves received by an antenna. The signal of the tuner 101 is input via the changeover switch 102 to encoding means 103 that MPEG-encodes the digitized video signal into video / audio data. The output of the encoding means 103 is input to a three-terminal matrix switch 104 whose input / output can be freely switched.
The matrix switch 104 inputs the output of the encoding unit 103 to a removable recording medium such as a DVD-R and inputs it to the second recording / reproducing unit 105 for reproducing. The recording medium of the second recording / reproducing means 105 is a DVD-R recording medium 106.
It is also connected to a first recording / reproducing means 110 that records and reproduces the output of the encoding means 103 from the matrix switch 104 to the hard disk 107. The MPEG encoded video / audio data of the first and second recording / playback means 105 and 110 are input via the matrix switch 104 to the decoding means 111 for MPEG decoding these signals into analog video / audio signals.

  Moreover, it has the EPG acquisition means 114 which acquires EPG (Electric Program Guide) information transmitted by being superimposed on the video / audio signal. There is a reserved recording control means 115 for controlling the entire reserved recording when a program is reserved based on the time information of the clock 113 and the EPG acquired by the EPG acquisition means 114. The associating means 108 gives a dubbing ID to related programs based on the information from the reserved recording control means 115. The classifying unit 109 classifies a plurality of programs associated with the dubbing ID into m (m is a natural number). Also provided is a user IF 150 connected to a push button (not shown) for a user (not shown) to perform various setting operations. When this button is pressed, the reserved recording control means 115 extracts and associates a series of related programs from the recorded program list, further classifies them into m program groups, and then selects m DVD- A dubbing start button 160 for sequentially dubbing a program group to R106 is provided.

  The operation at the time of recording is almost the same as that in the first embodiment, but a dubbing ID is not added at the time of recording, and a dubbing ID is added to a program newly added on the recorded program list 302 in FIG. Is not added. That is, the addition of the dubbing ID by the associating means 108 is executed only for the program data recorded on the first recording medium 107.

Next, the operation when dubbing is executed by the dubbing start button 106 will be described. When a dubbing start button 160 disposed on the main body or a remote controller (not shown) is pressed, the following processing is executed via the user IF 150.
First, for each program in the recorded program list 302 stored in the associating means 108, it is determined whether there is another program having the same recording start time, end time, day of the week, and channel information. If there is, the same dubbing ID is added to all programs whose information matches. If there is a program to which a dubbing ID is added among a plurality of programs having the same information, the ID is also added to all the programs having the same ID. Detailed processing is the same as that in the flowchart of FIG.

  In this way, the program to which the dubbing ID is added is extracted and the dubbing program list 303 is generated. When the generation of the dubbing program list is completed, the extracted series of multiple programs is divided into m according to the number of disks m (the number of disks m is automatically determined by the method described in the fourth embodiment). Automatic classification and sequential dubbing. The above-described series of flows is managed and controlled by the scheduled recording control means 115.

  If there are a plurality of program groups to which different dubbing IDs are added, as shown in FIG. 12, the display means “There are a plurality of program groups.
