2. Description of the Related Art
Recently, research and development regarding a DVD, which is an
optical disk having severalfold recording capacity than that of a
conventional CD (Compact Disk), has been done extensively.
A reproduction-only DVD in which a movie or the like is recorded
is popular. However, in addition to this, a standard of a DVD in which
video information such as moving image information and voice
information or the like are capable of being recorded (hereinafter,
referred to as video DVD), and a standard of a DVD in which audio
information including music information and voice information or the
like are capable of being recorded (hereinafter, referred to as audio
DVD), are being plotted out as a standard of a DVD capable of
recording.
In a video DVD standard of which plotting out has been nearly
completed, video information which is recorded from start of recording
to end thereof by a user (i.e., video information in a range capable of
being identified by the user as one group) is recorded as one group in a
DVD. In this case, upon recording the video information, reproduction
controlling information for controlling a reproduction manner of the
video information, which includes a reproduction order, a reproduction
time or the like, is also generated simultaneously and it is standardized
that the generated reproduction controlling information is recorded in
the DVD together with the video information. The reproduction
controlling information is also referred to as navigation information in
the video DVD standard.
On the other hand, in the case that a group of the video
information which is recorded once (hereinafter, referred to the group of
the video information as source video information) is video information
capable of being obtained by receiving, for example, television broadcast
or the like, a portion of the video information, specifically, for example,
a commercial message part, may be required to be deleted after
completion of recording the source video information.
In such a case, a video DVD recorder on sale which employs the
standard of the video DVD is configured in such a manner that this
video DVD recorder deletes a portion of the source video information in
accordance with an instruction from the user, divides source video
information and edits the reproduction controlling information
(hereinafter, referred to the reproduction controlling information as
source video reproduction controlling information) in response to the
source video information so as to reproduce the divided source video
information as one group, namely, to reproduce it as what is called one
program.
On the other hand, an audio DVD recorder employing the audio
DVD standard, whose standardization is in progress, is also expected to
be sold. However, in the case that one group of the audio information,
which is recorded after recording (hereinafter, referred to the group of
the audio information as source audio information), is divided by
deleting a portion thereof in this audio DVD recorder or the like, if the
dividing concept with respect to the above source video information is
intended to be employed as it is, it can be considered to edit the
reproduction controlling information in response to the source audio
information (hereinafter, referred to the reproduction controlling
information as source audio reproduction controlling information) so as
to reproduce all of the audio information after dividing as one group.
However, especially, for the audio information, there is a case that
applying a concept for dividing the above described video information is
inappropriate.
In other words, for example, in the case that the source audio
information is obtained by copying a plurality of music pieces recorded
in one piece of CD as they are, one group of the plural songs is recorded
as the source audio information. Further, the corresponding source
audio reproduction controlling information is also recorded so as to
control reproduction of the plural songs as one group.
In this case, in order to edit new reproduction controlling
information so as to extract and reproduce only a part of the plural
songs, it is necessary to designate a recording position of a song to be
reproduced from a head of the source audio information.
Simultaneously, also in the case of searching the recording position, at
first, it is necessary to start reproduction from a head of the source
audio information. As a result, this involves a problem such that an
unnecessary time is required to search the song and convenience is
extremely lowered upon editing new reproduction controlling
information.
The present invention has been made taking the foregoing
problem into consideration, an object of the invention is to provide an
information recording method and an information recording apparatus,

format for showing a recording positions or the like in the DVD of the respective
information). FIG. 2 is a diagram for showing a logical recording format generated so
as to control the reproduction manner of the audio information recorded in the DVD
(i.e., specifically, connection of the respective information upon reproduction and the
recording positions on the DVD of respective information to be connected).
At first, the physical format in the audio DVD standard will be described with reference
to FIG. 1. In FIG. 1, DVD 1 is a DVD capable of recording such as a DVD-R
(DVD-Recordable) which can be rewritten only once or a DVD-RW (DVD-Rewritable)
which can be rewritten in plural times.
As shown in FIO. 1, according to the standard of the audio DVD
a lead-in area LI, a data area DA and a lead-out area LO are formed
from its inner radius in the DVD 1. In the lead-in-area LI, starting
information or the like, which is controlling information to start
reproduction of the information in the DVD is recorded. In the data
area DA, reproduction controlling information to control the audio
information to be reproduced in practice and the reproduction manner
of the audio information is recorded. The reproduction controlling
information is specifically reproductiqn controlling information showing
reproduction order of respective information constructing the audio
information and reproduction time or recording positions on the DVD or
the like. In the lead-out-area LO, termination information or the like,
which is controlling information to terminate reproduction of the audio
information is recorded.
Next, a file system information area FSA, a navigation information
area NA and an object recording area ORA are formed in the above data
area DA.
Among the above areas, in the object recording area ORA a,
plurality of audio objects (AOB) which are the audio information
be recorded are recorded. In this case, a series of audio information
which is recorded during a period from recording is commenced once
until it is terminated, corresponding to an audio object use after the
recording is terminated. In other words audio objects are formed in
the object recording area ORA one by one every time a series of the
audio information is completely recorded.
Alternatively, FIG. 1 shows a state that n pieces of audio objects
are recorded as a first object OBJ1 to OBJn with being numbered,
respectively.
Additionally, in a logical format to be described later, a series of
audio objects which are recorded in the DVD 1 during a period from
recording is commenced once until it is terminated, is referred to as a
track.
Next, one audio object is comprised of a plurality of audio object
units AOBU. In this case, the audio object unit AOBU is recorded by
segmenting the audio object for every period of time (for example, for
every second) upon recording.
Alternatively, upon recording of the audio information, this audio
object unit AOBU becomes the minimum unit for edition or deletion of
the audio object.
On the other hand, in the navigation information area NA in the
data area DA, the reproduction controlling information is recorded as
the navigation information to control the reproduction manner of the
audio information recorded in the object recording area ORAS to be
described later.
Further, in the file system information area FSA system
information is recorded to store the above navigation information by
hierarchical structure in filling format in the navigation information
area NA.
Next, as the navigation information in the navigation information
area NA, navigation total information NT, an object file information table
OFT, object recording sequence information OSI, setting reproduction
sequence information UDI and other navigation information ET are
recorded.
Among the above information, the navigation total information NT
is comprised of navigation information managing information NM,
which is also called General Information (GI), and a reproduction list
pointer table PLT. The navigation information managing information
NM is total information of the DVD 1 for managing a storing position
(recording position) in respective sequences in the . navigation
information area NA or in the navigation information area NA of the
information table, and a recording starting position of the object
recording area ORA or the like. The reproduction list pointer table PLT
indicates a corresponding relation between the navigation information
stored in the setting reproduction sequence information UDI and a
reproduction list (referred to as play list (PL) in the audio DVD standard)
to be described later.
Next, the object file information table OFT is comprised of object
file attribution information OFZ and object file information OFI. The
object file attribution information OFZ comprises variety of object to be
recorded in the object recording area ORA and the attribution
information related to this variety or the like. The varity of object
indicates that objects to be recorded in the object recording area ORA is
an audio object in the case of the present embodiment. The object file
information OFI comprises a reproduction start time and a reproduction
termination time of respective: objects (audio object); which are the ones
in which a head of the first object OBJ1 is defined as a start point and the information related to them, or the like.
Further, in the object file information OFI, various information
related to one or a plurality of the above audio objects recorded on the
DVD 1 is recorded. Specifically, the various information is comprised
of object file total information OFO, L pieces of object search pointers
OBS (L is the number of the audio objects, which are recorded in the
DVD 1) and L pieces of object information OBS (namely, as many as the
object search pointer OBS). The object file total information OFG
includes total number or the like on the DVD 1 of the audio object at
the moment. The address information of heads of respective audio
objects to be searched (reproduced) in the reproduction processing or
the like to be described later, are described in the object search pointers
OBS. The address information or the like indicating a recording
position on the DVD 1 of heads of respective audio objects are described
in the reproduction processing or the like in the object information
OBS.
Furthermore, respective object information OBS are comprised of
object general information OI and object unit information UI. The
object general information OI comprises a reproduction start time and a
reproduction termination time of respective objects and the information
related to them. The object unit information UI comprises information
such as a reproduction time of the audio object unit AOBU constructing
respective audio objects, a recording start address or a size there often
the like
Next, the object recording sequences OSI is referred as an
original program chain ORG-PGC in the audio DVD standard. The
object recording sequence OSI is information indicating a recording
sequence of respective audio objects. Namely, it indicates in what
order, what audio information is recorded in the DVD 1 as the audio
object in the beginning of recording.
Additionally, the above described object file information,table OFT
and the object recording sequence OSI are newly, generated, updated
and recorded every time a new audio object is recorded in the DVD 1.
Due to these information, a user is capable of reproducing them by the
order and the reproduction time as same as those in the case that
respective audio objects are recorded.
On the other hand, the setting reproduction sequence information
UDI is referred to as a user defined program chain (UD-PGC) in the
audio DVD standard. The user generates one or plural setting
reproduction sequence information UDI in order to reproduce logically
all or a part of the recorded audio objects in a mutual, free and original
combination. The setting reproduction sequence information UDI are
recorded with being numbered every time the user newly sets them. In
this case, the user defined program chain is associated with the reproduction list described above.
Further, other navigation information ET is comprised of the
information necessary for controlling reproduction in addition of the
above described respective navigation information.
Next, pointer information is recorded as a reproduction list
pointer table PLT. The pointer information shows a corresponding
relation between the number of one or a plurality of the above setting
reproduction sequence information UDI which are recorded on the DVD
1 at the moment, and the number of the reproduction list set by the
user. Specifically, the reproduction list pointer table PLT is comprised
of play list total information PLG and a first to m-th reproduction list
pointers PLT 1 to PLT m. The play list total information PLG includes a
final address or the like in a region on the DVD 1 where the total
number at the moment of the pointer information and the reproduction
list pointer table PLT are recorded. The reproduction list pointers PLT
1 to PLT m indicate the numbers of the setting reproduction sequence
information UDI, which, are associated with the first to the m-th
reproduction lists set by the user in the above setting reproduction
sequence information UDI, respectively-
Next, a logical format for logically controlling a reproduction
manner upon reproducing the audio information, which is recorded in
the DVD 1 in accordance with the above described physical format, will
be described with reference to FIG. 2. The reproduction manner
includes the reproduction order or a range of the audio information to
be reproduced in the audio information.
FIG. 2 is a diagram for showing the logical format in a
hierarchical structure. However, the audio information on the DVD 1
is recorded in a manner as shown in FIG. 1 and the logical
obtained as a result that a range and a reproduction order of the audio
respective navigation information
described above.
At first a logical format of the above object recording seqence
information OSI will be described.
As described above, the object recording sequence information
OSI is information indicating a recording sequence of respective audio
objects. However, in the case of reproducing the audio objects on the
basis of the object recording sequence information OSI, the user may be
allowed only to reproduce the audio objects in an order of recording, so
that there is only one reproduction manner.
In other words, a first track TR1 is recorded prior to a second
track TR2 in FIG. 2. However, in this case, a reproduction order
capable of being set as the object recording sequence information OSI
has only an order from the first track TR1 to the second track TR2.
The first track TR1 is a track corresponds to a series of the audio
objects to be recorded in the DVD 1 during a period from recording is
commenced once until it is terminated as described above.
Further, one track TR is logically comprised of one or a plurality
of of cells CL. The cells CL are all or a part of one track. In one cell
CL, the audio information is standardized such that they should be
successive. In other words, one track TR is comprised of one cell CL or
more.
Assuming that, for example, a broadcast program for an hour is
recorded in the DVD 1 as the audio object, one track TR is comprised of
only one cell CL as shown in the second track TR2 and the third cell
CL3 of FIG. 2 in this state.
On the other hand, in the case that the object recording sequence
OSI is set in such a manner that the track TR is divided before and after
a part of the formed one track TR so that a part of the formed one track
TR is not capable of being reproduced after the recording, it is only
standardized that the cell CL is divided before and after a part, which is
not capable of being reproduced in the audio DVD standard (refer to the
first track TR1, the first cell CL1 and the second cell CL2 in FIG. 2).
For example, the case corresponds to a case that the audio object
corresponding to a period of a commercial message during the
broadcast program has been on air is deleted so that it cannot be
reproduced, or one track TR is divided for each song after this one track
TR is formed by plurality of songs or the like.
In the above case, as described later, according to the present
embodiment, the object recording sequence information OSI is edited so
that the track TR itself is divided in accordance to division of the cell CL
(refer to FIG. 5 to be described later).
Next, in a relation between respective cells CL physically
configured, and respective audio objects logically formed, one cell CL is
ordinary associated with one audio object as shown in FIG. 2.
Therefore, for example, if one cell CL is deleted on the object recording
sequence information OSI, a corresponding audio object also becomes
unnecessary to be reproduced.
Further, a logical format of the above setting reproduction
sequence information UDI will be described.
As described above, the setting reproduction sequence
information UDI (user defined program chain) is also referred to as a
reproduction list in the audio DVD standard. The user sets and
records the setting reproduction sequence information UDI so that the
user can arbitrarily reproduce a part or all of a plurality of audio objects
in an arbitrary order.
In the above case, the above described track TR does not exist in
the setting reproduction sequence information UDI. Further, it is
possible to set a plurality of setting reproduction sequence information
UDI.
Next, one setting reproduction sequence information UDI is
logically comprised of one or a plurality of defined cells UD as shown in
FIG. 2. In this case, one defined cell UD comprises information, which
logically shows reproduction segments arbitrarily set by the user
(reproduction segments as a part of the respective audio objects) and a
reproduction order between respective reproduction segments. This
defined cell UD is set so as to reproduce respective audio objects with
making reference to them. This is an artifice in a standard to realize a
plurality of reproduction manners with changing original audio objects
as little as possible.
More specifically, as shown in FIG. 2, logically setting a first
defined cell UDI, a second defined cell UD2, a third defined cell UD3
and a fourth defined cell UD4, then, one setting reproduction sequence
information UDI is comprised of defining these defined cells so that they
are reproduced in such an order that the first defined cell UDI, the
second defined cell UD2, the third defined cell UD3, and the fourth
defined cell UD4. The first defined cell UDI designates a part of the
first object OBJ1 as a reproduction segment. The second defined cell
UD2 designates a part of the second object OBJ1 as a reproduction
segment. The third defined cell UD3 and the fourth defined cell UD4
designate various parts of the third object OBJ3, respectively, as
reproduction segments.
Next, an embodiment according to the present invention will be
described with reference to FIG. 3 to FIG. 8.
At first, a schematic configuration of an information recording
reproduction apparatus according to the present embodiment will be
described with reference to FIG. 3. FIG. 3 is a block diagram for
showing a schematic configuration of the information recording
reproduction apparatus.
As shown in FIG. 3, an information recording reproduction
apparatus S according to the embodiment is comprised of a pickup 2 as
a recording device, a modulator 3, a formatter 4, an encoder 5, a timing
generator 6, a system controller 7 as a generating and recording device,
a memory 9, a demodulator 10, a decoder 11, a switch 12, a servo IC
(Integrated Circuit) 13, a spindle motor 14 and an operation unit 15 as
a designation device and a reproduction designation device.
Additionally, the system controller 7 is provided with a navigation
information generator 8.
Further, the timing generator 6 is comprised of a detecting circuit
6A and an addition circuit 6B.
Next, schematic operations of respective units will be explained
below.
The spindle motor 14 rotates the DVD 1 with predetermined
number of revolutions on the basis of a spindle controlling signal Sss
from the servo IC13.
On the other hand, recording information Sr including the audio
information to be recorded in the DVD 1 is inputted from the outside,
then, it is inputted in the encoder 5, one input terminal of the switch 12
and the detecting circuit 6A.
Further, the encoder 5 performs a predetermined encoding
processing, which is specifically, for example, compression encoding
processing in an MPEG (Moving Picture Experts Group) system, with
respect to the recording information Sr on the basis of a controlling
signal Sce from the system controller 7 and generates a encoding signal
Sre to output it to the formatter 4.
Thus, the formatter 4 superimposes a navigation information
signal Snd from the navigation information generator 8 to be described
later and the above encoding signal Sre on the basis of a controlling
signal Scf from the system controller 7 so that they are formed in a
physical format. Then, the formatter 4 generates a superimposed
signal Sf to output it to the modulator 3.
After that, the modulator 3 provides the superimposed signal Sf
with predetermined modulation processing, which is specifically, for
example, 8-16 modulation processing, and generates a modulation
signal Sfe to outputted it to the pickup 2.
Thus, the pickup 2 generates an optical beam B, whose strength
is modulated by the modulation signal Sfe, and irradiates, it to an
information track in an information recording surface (not illustrated) of
the DVD 1, so that pits in associated with the navigation information,
which is included in the modulation signal Sfe and the audio
information are generated on the information track. Thus, the pickup
2 records the navigation information and the audio information on the
DVD 1 in a physical format shown in FIG. 1.
In the above case, an objective lens (illustrate) in the pickup 2 (an objective lens for
condensing the optical beam B) is moved in the above vertical and horizontal directions
on the basis of a pickup servo signal Ssp to be outputted from the servo IC 13. Namely,
focus servo controlling and tracking servo controlling are performed. As a result, the
declination between a condensing position of the optical beam B and the above
information track in a vertical and horizontal directions with respect to the above
information recording surface is dissolved.
Therefore, the servo IC13 generates the above spindle controlling signal Sss and a
pickup signal Ssp on the basis of a controlling signal Ssc from the system Controller 7
to output these signals to the spindle motor 14 and the pickup 2, respectively.
On one hand, in the case of reproducing the audio information or the like, which has
been already recorded in the DVD 1, the pickup 2 generates the optical beam B to be
reproduced having certain strength and irradiates it to the information track in which the
above pits are formed. Then, the pickup 2 generates a detecting signal Spp in
associated with the audio information or the like on the basis of its reflection light and
outputs it to be demodulator 10.
Thus, the demodulator 10 provides the detecting signal Spp with demodulation
processing in associated with the modulation processing in the above modulator 3, and
generates a demodulation signal Spd to output it to the decoder 11.
Then, the decoder 11 provides the demodulation signal Spd with decoding processing in
associated with the encoding processing in the above encoder 5 on the basis of a
controlling signal Scd from the system
controller 7, and generates a decoding signal Sd to output it to other
input terminal of the switch 12 and the detecting circuit 6A.
After that, the switch 12 selects any one of the above recording
information Sr and the above decoding signal Sd on the basis of a
controlling signal Scs from the system controller 7 and outputs it to an
exterior amplifier or the like (not illustrated) as an output signal Sout.
Alternatively, in the editorial processing of the embodiment to be
described later, the switch 12 is always switched to a decoding signal
Sd's side.
On the other hand, the operation unit 15 generates an operation
signal Sin in associated with the operation and outputs it to the system
controller 7 through the timing generator 6 when the operation is
performed by the user to perform the processing in the information
recording reproduction apparatus S.
Upon performing the editorial processing of the embodiment to be
described later, when the operation is performed to divide respective
tracks TR, the operation unit 15 generates the operation signal Sin
indicating that respective tracks TR arc divided in this timing.
Next, upon performing the above editorial processing, the timing
generator 6 generates a timing signal Stm indication a timing at which
the edition should be performed oh the basis of the above recording
information Sr, the decoding signal Sd and the operation signal Sin
output this signal to the navigation information generator 8,
More specifically, the detecting circuit 6A in the timing generator
6 detects the recording information Sr and a silent portion of the
decoding signal Sd, and generates a detecting signal Spu to output it to
the addition circuit 6B. Then, the addition circuit 6B adds the
detecting signal Spu and an operation signal Sh from the operation unit
15, and generates the above timing signal Stm to output it.
Thus, the timing signal Stm is outputted to the navigation
information generator 8 at both of a timing that the above dividing
operation is performed in the operation unit 15 and a timing that the
detecting circuit 6A detects the recording information Sr and the silent
portion of the decoding signal Sd.
Alternatively, in the case that the recording information Sr has
boundary information showing a boundary of a song in its data, the
detecting circuit 6A detects this boundary information.
Thus, the navigation information generator 8 generates the above
navigation information signal Snd including the above respective
navigation information after the editorial processing on the basis of the
timing signal Stm and outputs it to one input terminal of the formatter
4.
As a result, the audio information in the encoding signal Sre and
the navigation information in the navigation information signal Snd are
superimposed by the above formatter 4, so that the above superimposed
signal Sf including the audio information or the like, which has the
physical format shown in FIG. 1, is generated.
In parallel with these operations, the system controller 7 gives
and receives information necessary as a memory signal Sm to and from
the memory 9, generates respective controlling signals See, Scf, Ssc,
Scd and Scs for controlling the above respective operations and outputs
them to component materials in associated with respective controlling
signals.
Next, editorial processing of the object recording sequence
information OSI according to the embodiment will be explained with
reference to FIG. 4 to FIG. 6.
Additionally, the editorial processing to be described below edits
the track TR, which is recorded once in the DVD 1 in accordance with
the physical format shown in FIG. 1, and the object recording sequence
information OSI in associated with the track TR so that they are divided
after the recording.
Alternatively, FIG. 4 is a flow chart for showing the editorial
processing, which is mainly performed in the system controller 7. FIG.
5 and FIG. 6 are diagrams for specifically illustrating the object
recording sequence information OSI before and after the division.
As shown in FIG. 3, according to the editorial processing of the
present embodiment, at first, reproduction of the audio information,
which has been already recorded in the DVD 1 as the track TR (a track
TR to be divided), is commenced (step SI). In this case the switch 12,
which has been switched to the decoding signal Sd's side reproduces
the audio information via the pickup 2, the demodulator 10, the
decoder 11 and the switch 12.
If reproduction of the audio information is commenced, then, it is
determined whether the desired dividing processing, i.e., the editorial
processing of the object recording sequence information OSI is
completed or not (step S2). If it is all completed (step S2; YES),
termination processing is performed (step S3) and the editorial
processing is terminated. For example, the termination processing
includes the processing of recording of the termination information to
be recorded in the lead-out area LO or the like.
On one hand, in the determination in the step S2, if all of the
editorial processing is not completed (step S2; NO), then, it is
determined whether or not the operation signal Sin indicating that the
track TR is divided is inputted from the operation unit 15 (step S4).
Further, if the operation signal Sin is not inputted (step S4; NO), the
processing returns to the step S2 so as to wait until the operation signal
Sin is inputted. On the contrary, if it is inputted (step S4; YES), then,
it is determined whether or not the division timing indicated by the
timing signal Stm in associated with the operation signal Sin is a timing
in the middle of reproduction of one audio object unit AOBU.(step S5).
Further, if the division timing is a timing in the middle of
reproduction of one audio object unit AOBU (step S5; YES), the
processing waits until a timing that the reproduction of the audio object
unit AOBU is terminated comes since it is assumed that the editorial or
deletion processing or the like is not performed in the middle of one
audio object unit AOBU as described above.
On the other hand, if the division timing indicated by the timing
signal Stm is not a timing in the middle of one audio object unit AOBU
(step S5; NO), then, the address information in a recording termination
position in the audio object to be reproduced before the division timing
in the corresponding object recording sequence information OSI and a
reproduction termination time of the cell CL to be reproduced before the
division timing are changed on the object recording sequence
information OSI (step S6). Simultaneously, updating of a track
number of a new track TR, of which the reproduction is commenced
after the division timing, and the audio object number and rewriting of
the address information of the address information in the recording
start position of the new track TR are performed on the object recording
sequence information OSI (step S7). Then, at the next division timing,
the processing returns to step S2 so as to repeat the same processing.
Next, it is clearly explained how the object recording sequence
information OSI is edited in the above editorial processing with
reference to FIG. 5 and FIG. 6.
Additionally, according to a following explanation, in one DVD 1,
a first track 20 having a reproduction time of 19 minutes, 59 seconds
and 2 frames (1 frame is equivalent to 1/30 second) shown in the
logical format in FIG. 5 is divided into a first track 30, of which
reproduction time is just 10 minutes, and a second track 31, of which
reproduction time is 9 minutes, 59 seconds and 2 frames.
Simultaneously, according to a following explanation, a second track 21
having a reproduction time of 29 minutes, 59 seconds and 29 frames is
divided into a third track 32, of which reproduction time is just 15
minutes, a fourth track 33, of which reproduction time is just 10
minutes, and a fifth track 34, of which reproduction time is 9 minutes,
59 seconds and 29 frames.

audio object 22 and a first cell 24 are associated with the first track 20
before division. Simultaneously, a second audio object 23 and a
second cell 25 are associated with the second track 21.
Alternatively, after division, a first audio object 35 and a first cell
40 are associated with the first track 30, a second audio object 36 and a
second cell 41 are associated with the second track 31, a third audio
object 37 and a third cell 42 are associated with the third track 32, a

Next, reproduction processing of an embodiment by the use of the
object file information OFI or the like illustrated in FIG. 7 will be
described with reference to FIG. 8.
Alternatively, the switch 12 is switched to the decoding signal
Sd's side when the reproduction processing is performed
Additionally, reproduction processing explained below is
reproduction processing for searching a position after a time of Ts
seconds from a head of the data area DA in the DVD 1 as a
reproduction time and reproducing the audio information recorded in
this position. In this case, reproduction time in associated with one
audio object unit AOBU is assumed to be t seconds.
As shown in FIG. 8, according to the reproduction processing, at
first, when the reproduction time Ts is designated by the user (step
S20), a parameter n indicating the number of the audio object is set to
"1" (step S21). The number is a continuous number in the case that
the number of the audio object recorded in a head of the data area DA
is assumed to be "1". Then, the reproduction time Tn at the head of
the audio object to be illustrated by the parameter n is compared with
the above reproduction time Ts (step S22).
If the reproduction time Tn is ahead of the reproduction time Ts
(step S22; YES), it is assumed that the irradiating position of the optical
beam B does not reach a desired reproduction position. Then, the
parameter n is increased by "1" (step S23) and the processing returns to
the step S22.
On one hand, if it is determined that the reproduction time Tn is
behind of the reproduction time Ts in the step S22 (Step S22; NO), it is
assumed that the irradiating position of the optical beam B passes the
desired reproduction position by one audio object. Then, the
parameter n is decreased by "1" (step S24). Therefore, a n-th audio
object obtained by this processing is an audio object including the
reproduction time Ts. Next, difference between the reproduction time
Tn and the reproduction time Ts is divided by the reproduction time t of
one audio object unit AOBU and its quotient is defined as k and its
remainder is defined as r (step S25).
According to this processing in the step S25, it is perceived that
the desired reproduction time Ts is equivalent to a position after r
seconds from the head of the k-th audio object unit AOBU in the n-th
audio object.
Next, detection of the k-th audio object unit AOBU is commenced
(step S26). Further, the audio information is reproduced from a
position after r seconds from the above position (step S27) and the
processing is terminated.
As described above, according to the dividing processing of the
track TR by edition of the object recording sequence OSI of the
embodiment, generating the object recording sequence information OSI'
after division to record it in the DVD 1 as shown in FIG. 6B is repeated
every time the division is designated, so that it is possible to record the
object recording sequence information OSI' for dividing the original
track TR (the first track 20 and the second track 21) in a manner
desired by the user to reproduce it.
Additionally, since the recorded audio information is reproduced
and simultaneously division is designated, it is possible that the user
confirms the contents of the audio information and simultaneously the
object recording sequence information OSI' after division is generated.
Further, since respective cell information in the object recording
sequence information OSI' include the reproduction time information of
respective cells after division and the order information, it is possible
that respective tracks after division are capable of being certainly
reproduced in a reproduction manner, which is desired by the user.
Further, since the DVD 1 capable of recording is used as the
information recording medium, large quantity of audio information can
be recorded and simultaneously reproduced in such a manner that the
user desired.
(III) Modified Embodiment
Next, a modified embodiment of the present invention will be
described with reference to FIG. 9.
FIG. 9 is a flow chart for illustrating editorial processing
according to a modified embodiment of the present invention.
In the above described embodiment, the editorial processing for
reproducing the audio information, which is once recorded, and
simultaneously dividing the track TR is described. However, in
addition to this, the present invention can be also applied to the case
that a series of the audio information is divided and recorded upon
recording this series of the audio information in the DVD 1, in which no
audio information is recorded.
Since the configuration of the information recording reproduction
apparatus according to the modified embodiment is the same as the
configuration of the information recording reproduction apparatus S of
the embodiment other than that the switch 12 is always switched to the
recording information Sr's side, the explanation thereof is omitted
below.
In the editorial processing in the modified embodiment, as shown
in FIG. 9, at first, the audio information recording is commenced (step
S10). Then, the audio object unit AOBU is generated by the above
described processing to be recorded in the DVD 1 (step S11).
After that, it is determined whether or not the audio information
recording is completed or not (step S12). If the recording processing is
not completed (step S12; NO), then, it is determined whether a
boundary of a song in the recording information Sr is detected (step
S14).
In the above case, in the processing of the step S14, specifically,
the boundary is detected at timing that the detecting circuit 6A in the
timing generator 6 detects the silent portion of the recording
information Sr.
When the boundary of the song is detected by the determination
in the step S14 (step S14; YES), the address information of the
recording termination position in the audio object to be reproduced
before the boundary timing in the corresponding object recording
sequence information OSI and the reproduction termination of the cell
CL to be reproduced before the boundary timing are newly generated as
the object recording sequence information OSI (step S16). Further, a
new audio object and a new track TR are generated with respect to the
audio information, which has been recorded up to the boundary (steps
S17 and S18) and the processing returns to the step S11 so as to repeat
the same processing at the boundary timing to come next.
On one hand, if the boundary of the song is not detected in the
determination of the step S14 (step S14; NO), then, it is determined
whether or not the operation signal Sin, which intends to divide the
track TR generated up to that time, is inputted from the operation unit
15 (step S15). If the operation signal Sin is not inputted (step S15;
NO), the processing shifts to the step Sll as it is. On the contrary, if it
is inputted (step S15; YES), the processing shifts to the above step S16
and performs the above described processing thereafter.
If it is detected that recording processing is completely terminated
in the determination of the step S12 (step S12; YES), then, the address
information of the recording termination position in the last audio
abject and the reproduction termination time of the last cell CL are
generated as the object recording sequence information OSI (step S19).
Then, the predetermined termination processing is performed (step S20)
and the recording processing is terminated. The predetermined
termination processing includes, for example, the processing of
recording of the termination information to be recorded in the read out
area LO or the like.
As the object recording sequence information OSI to be generated
after the editorial processing shown in FIG. 9 is performed, for example,
the object recording sequence information OSI illustrated in FIG. 6A is
generated as well as the recording processing. In this case, the
boundary of the song is detected in the audio information to be
recorded only when ten minutes zero second has been passed after the
recording is commenced.
As described above, according to the editorial processing of the
object recording sequence information OSI in the modified embodiment,
the object recording sequence information OSI before and after the
