Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
In the present embodiment, the present invention is employed for generating a reproduction list for sequentially reproducing each of audio information and video information from a DVD that is an information recording medium in which the audio information and video information are recorded respectively in individual regions, and for sequentially reproducing each of the information irrespective of the audio information or the video information
(I) Embodiments of Each Recording Standard
Prior to describing the preferred embodiments according to the present invention, a recording format in the audio recording standard and the video recording standard that are a premise of the preferred embodiments will be described with reference to FIG. 1 and FIG. 2.
The audio and video recording standards have common structures in basic recording format with the exception of the fact that an attribute of information to be recorded is audio information or video information In the following description, these standards will be described in common as recording standards.
FIG. 1 is a diagram for showing a physical format in a DVD after either of the audio information or video information (hereinafter, simply referred to as recording information) is recorded on the basis of each of the recording standards (i.e., specifically, a physical format for showing a recording positions or the like in the DVD of the respective recording information). FIG. 2 is a diagram for showing a logical recording format generated so as to control the reproduction manner of the recording information recorded in the DVD (i.e., specifically, connection of the respective information upon reproduction and the recording positions on the DVD of respective recording information to be connected).
At first, the physical format in each of the recording standards 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-Recordable) which can be rewritten in plural times.
As shown in FIG. 1, according to each of the recording standards, 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 recording information in the DVD is recorded. In the data area DA, reproduction controlling information to control the recording information to be reproduced in practice and the reproduction manner of the recording information is recorded. The reproduction controlling information is specifically reproduction controlling information showing reproduction order of respective information constructing the recording 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 recording 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 objects which are the recording information itself to be recorded are recorded. Each of the objects is defined as audio object (AOB) when recording information is audio information or defined as video object (VOB) when recording information is video information. In this case, a series of the recording information, which is recorded during a period from recording is commenced once until it is terminated, corresponds to one recording object just after the recording is terminated. In other words, the objects are formed in the object recording area ORA one by one every time a series of the recording information is completely recorded.
Alternatively, FIG. 1 shows a state that n pieces of the 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 the 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 program. The term “program” is used when recording information is video information, and a term “track” is used when recording information is audio information
Next, one object is comprised of a plurality of object units OBU. Each of the object units is defined as audio object unit (AOBU) when the recording information is audio information and defined as video object unit VOBU when the recording information is video information. In this case, the object unit OBU is recorded by segmenting the object for every period of time (for example, for every second) upon recording.
Alternatively, upon recording of the recording information, this object unit OBU becomes the minimum unit for edition or deletion of the 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 recording information recorded in the object recording area ORA 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 each of the recording standards) 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 objects to be recorded in the object recording area ORA and the attribution information related to this variety or the like. The variety of objects indicates that objects to be recorded in the object recording area ORA is an audio object or a video object in the case of the present embodiment. The object file information OPI comprises a reproduction start time and a reproduction termination time of respective objects, which are the ones in which a head of the first object OBJ 1 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 objects recorded on the DVD 1 is recorded. Specifically, the various information is comprised of object file total information OFG, L pieces of object search pointers OBS (L is the number of the 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 object at the moment. The address information of heads of respective 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 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 object unit OBU constructing respective objects, a recording start address or a size thereof or the like.
Next, the object recording sequence OSI is referred to as an original program chain (ORG-PGC) in each of the recording standards. The object recording sequence OSI is information indicating a recording sequence of respective objects. Namely, it indicates in what order, what recording information is recorded in the DVD 1 as the 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 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 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 each of the recording standards. The user generates one or plural setting reproduction sequence information UDI as reproducing procedure information in order to reproduce logically all or a part of the recorded objects in a mutual, free and original combination. The setting reproduction sequence information UDI are recorded as the reproducing procedure information 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 to 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 reproduction 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 recording 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 recording information to be reproduced in the recording information.
FIG. 2 is a diagram for showing the logical format in a hierarchical structure. However, the recording information on the DVD 1 is recorded in a manner as shown in FIG. 1 and the logical format is obtained as a result that a range and a reproduction order of the recording information to be reproduced are described by using the above respective navigation information in a hierarchical structure, as described above.
At first, a logical format of the above object recording sequence information OSI will be described.
As described above, the object recording sequence information OSI is information indicating a recording sequence of respective objects. However, in the case of reproducing the objects on the basis of the object recording sequence information OSI, the user may be allowed only to reproduce the objects in an order of recording, so that there is only one reproduction manner.
In other words, a first program PG1 is recorded prior to a second program PG2 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 program PG1 to the second program PG2. The first program PG1 is a program corresponds to a series of the 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 program PG is logically comprised of one or a plurality of cells CL. The cells CL are all or a part of one program PG. In one cell CL, the recording information is standardized such that they should be successive. In other words, one program PG 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 object, one program PG is comprised of only one cell CL as shown in the program PG2 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 program PG is divided before and after a part of the formed one program PG so that a part of the formed one program PG 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 each of the recording standards (refer to the first program PG1, the first cell CL1 and the second cell CL2 in FIG. 2). For example, the case corresponds to a case that the 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 the like.
Next, in a relation between respective cells CL physically configured, and respective objects logically formed, one cell CL is ordinary associated with one object as shown in FIG. 2. Therefore, for example, if one cell CL is deleted on the object recording sequence information OSI, a corresponding 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 each of the recording standards. 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 the objects in an arbitrary order.
In the above case, the above described program PG 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 (sometimes referred to as logical cells) 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 objects) and a reproduction order between respective reproduction segments. This defined cell UD is set so as to reproduce respective objects with making reference to them. This is an artifice in a standard to realize a plurality of reproduction manners with changing original objects as little as possible.
More specifically, as shown in FIG. 2, logically setting a first defined cell UD1, 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 UD1, the second defined cell UD2, the third defined cell UD3, and the fourth defined cell UD4, The first defined cell UD1 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.
In the case where two or more definition cells UDs are defined for one object, part of the objects may used in common in a plurality of definition cells UDs.

(III) Embodiments of Recording and Reproduction Processing
Next, processing for generating the described integrated reproduction list GL to record in the DVD 1 and reproducing from DVD 1 the video information and audio information by employing the recorded, integrated reproduction list GL will be described with reference to FIG. 10 to FIG. 13.
FIG. 10 is a block diagram showing a general configuration of an information recording and reproducing apparatus according to the preferred embodiment employed for the recording processing and reproduction processing. FIG. 11 is a flow chart illustrating recording processing of the integrated reproduction list GL. FIG. 12 and FIG. 13 are flow charts each showing reproduction processing employing the integrated reproduction list GL.
First, a general configuration of an information recording and reproducing apparatus that executes the recording processing and reproduction processing, will be described with reference to FIG. 10, FIG. 10 is a block diagram showing a general configuration of the information recording and reproducing apparatus.
The following description concerns recording processing and reproduction processing in an information recording and reproducing apparatus capable of recording in the DVD 1′, computer data information as well as the above video information and audio information, and capable of reproducing the information from the DVD 1′.
As shown in FIG. 10, an information recording reproduction apparatus S according to the embodiment is comprised of a pickup 2 as a recording device and a reproducing device, a modulator 3, a formatter 4, a video encoder 5, an audio encoder 6, a system controller 7 as an acquiring device, a memory 9, a demodulator 10, a video decoder 11, an audio decoder 12, a servo IC (Integrated Circuit) 13, a spindle motor 14 and an operation unit 15 as a selecting device, a multiplexer 16, and a demultiplexer 17.
Additionally, the system controller 7 is provided with a navigation information generator 8 as a generating device and a procedure information generating device.
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.
Video information Sv that is recording information to be recorded in the video object recording area VOR in the DVD 1′ is inputted from the outside, then, it is inputted in the video encoder 5.
Further, the video 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 video information Sv on the basis of a controlling signal Scv from the system controller 7 and generates a encoding video signal Sev to output it to the multiplexer 16.
On the other hand, audio information Sa that is recording information to be recorded in the audio object recording area AOR in the DVD 1′ is inputted from the outside, then, it is inputted in the audio encoder 6.
Then, the audio encoder 6 performs a predetermined encoding processing, which is specifically, for example, compression encoding processing in the MPEG system, with respect to the audio information Sa on the basis of a control signal Sca from the system controller 7 and generates an encoding video signal Sea to output it to the multiplexer 16.
Further, data information Sdu that is recording information to be recorded in the DVD 1′ is inputted from the outside, then it is directly outputted to the multiplexer 16.
In this manner, the multiplexer 16 superimposes (multiplexes) the image information on the voice information respectively contained in the encoding video signal Sev by means of predetermined processing, and generates a multiplex signal Smx to output it to the formatter 4.
At this time, the multiplexer 16 passes the encoding audio signal Sea and data information Sdu intact, and generates a multiplex signal Smx.
Next, the formatter 4 combines a navigation information signal Snd from the navigation information generator 8 to be described later and the multiplex signal Smx on the basis of a controlling signal Scf from the system controller 7 so that they are formed in a physical format in FIG. 5. Then, the formatter 4 generates a format signal Smt to output it to the modulator 3.
At this time, each of recording information inputted as the multiplex signal Smx to the formatter 4 is outputted as a recording information signal Sfm to the system controller 7 at a predetermined timing in order to generate the navigation information in the navigation information generator 8.
After that, the modulator 3 provides the format signal Smt 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 each of the recording information are generated on the information track Thus, the pickup 2 records the navigation information and each of the recording information on the DVD 1′ in a physical format shown in FIG. 5.
In the above case, an objective lens (not illustrated) 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 servo 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 recording 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 recording information or the like on the basis of its reflection light and outputs it to the decoder 10.
Thus, the decoder 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 demultiplexer 17.
When the demodulation signal Spd includes the video information, the demultiplexer 17 separates the image information and voice information contained in the video information from each other, and generates a separate signal Sdmx to output it to the video decoder 11.
When the demodulation signal Spd includes the audio information, the demutiplexer 17 passes the demodulation signal Spd intact, and outputs it to the audio decoder 12.
Further, when demodulation signal Spd includes the data information, the demultiplexer 17 passes the demodulation signal Spd intact, and outputs data information Sdu to an external computer (not shown) or the like.
The demultiplexer 17 extracts each of the above navigation information from among the modulation signal Spd, and outputs a extracting navigation signal Snv to the system controller 7 during generation of the integrated reproduction list GL described later or the like.
Then, the video decoder 11 provides the separate signal Sdmx with decoding processing in associated with the encoding processing in the video encoder 5 on the basis of a controlling signal Scdv from the system controller 7, and generates a decoding video signal Sdv to output it to an external monitor (not shown) or the like.
Further, the audio decoder 12 provides the demodulation signal Spd including the audio information with decoding processing in associated with the encoding processing in the audio encoder 6 on the basis of a control signal Scda from the system controller 7, and outputs it to an external amplifier (not shown) or the like.
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 when the operation is performed by the user to perform the recording and reproducing processing in the information recording reproduction apparatus S.
Further, the navigation information generator 8 generates the above navigation information signal Snd including the above respective navigation information to be recorded on the DVD 1 during recording processing described later, and outputs it to one input terminal of the formatter 4, under the control of the system controller 7 based on the operation signal Sin and recording information signal Sfm.
As a result, the recording information in the multiplex signal Smx and the navigation information in the navigation information signal Snd are superimposed by the above formatter 4, so that the format signal Smt including the recording information, which has the physical format shown in FIG. 5, 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 Scv, Sca, Scf, Ssc, Scdv and Scda for controlling the above respective operations and outputs them to component materials in associated with respective controlling signals.
Next, recording processing for recording the integrated reproduction list GL according to the preferred embodiments in the DVD 1′ in accordance with a physical format shown in FIG. 5, will be described with reference to FIG. 11.
The recording processing shown in FIG. 11 is mainly executed by the system controller 7 and navigation information generator 8.
In recording the integrated reproduction list GL, the video navigation information area VNA, audio navigation information area ANA, video object recording area VOR and audio object recording area AOR shown in FIG. 5, have been already formed on a DVD 1′ in the manner shown in FIG. 5 by using a known method for forming a physical format shown in FIG. 1.
In recording processing of the integrated reproduction list GL, as shown in FIG. 11, it is determined whether or not the integrated reproduction list GL is instructed to be formed at the operating portion 15 (step S1). When the result of the determination is negative (step S1 NO), processing is terminated. When the result of the determination is affirmative (step S1: YES), it is checked whether recording information for acquiring the reproduction list as the integrated reproduction list GL is the video information or the audio information (step S2).
When the recording information for acquiring a reproduction list is the video information (step S2: Video), the corresponding reproduction list is selected and extracted as the extracting navigation signal Snv from among the setting reproduction sequence information UDI formed in the video navigation information area VNA shown in FIG. 5. Then, the selected and extracted signal is temporarily stored in a memory (not shown) in the system controller 7 (step S3).
When it is determined that recording information for acquiring the reproduction list is the audio information (step S2: Audio) at the step S2, the corresponding reproduction list is selected and extracted as the extracting navigation signal Snv from among the setting reproduction sequence information UDI formed in the audio navigation information area ANA shown in FIG. 5. Then, the selected and extracted signal is temporarily stored in the above memory (not shown) (step 4).
When the reproduction list to be acquired has been selected and extracted, it is then determined whether or not to terminate selection and extraction of the reproduction list as the integrated reproduction list GL (step S5). When the result of the determination is negative (step S5. NO), processing returns to the step S2 at which each of the above processes is repeated. When the result of the determination is affirmative (step S5: YES), the selected and extracted reproduction lists are acquired in order when they are selected, and the integrated reproduction list GL and integrated reproduction list pointer table GPT are generated in the manner shown in FIG. 9 (step S6) The generated list and table are recorded in the integrated navigation information area GNA in the DVD 1′ (step S7), then processing is terminated.
Next, recording information reproduction processing employing the integrated reproduction list GL recorded by the above described recording processing, will be described with reference to FIG. 12 and FIG. 13.
First, recording information reproduction processing employing each reproduction list that is a premise of the reproduction processing, will be described with reference to FIG. 12.
In reproduction processing employing the reproduction list, as shown in FIG. 12, the reproduction list having the manner to be reproduced is first selected at the operating portion 15 (step S20). Next, the number of the setting reproduction sequence information UDI that corresponds to the selected reproduction list is specified by reading the reproduction list pointer (refer to reference code PLT shown in FIG. 1) (step S21). Further, each of reproduction sequence information start address information (refer to reference numerals 51 and 52 shown in FIG. 7 or reference numerals 56 to 58 shown in FIG. 8) is specified in accordance with the number of the specified setting reproduction sequence information UDI, thereby specifying a recording position of each of setting reproduction sequence information UDI (step S22).
Each of the defined cell information contained in the specified setting reproduction sequence information UDI (refer to reference numerals 53E to 53G and 54C shown in FIG, 7 or reference numerals 59D, 59E, 60C, 61D and 61E) is acquired at the recording position of the specified setting reproduction sequence information UDI (step S23). Then, the corresponding object file information table OFT (refer to FIG. 1) is referred to by employing the object number contained in each of the defined cell information, and the recording position of the object OBJ to be reproduced is acquired (step S24). Further, in parallel to this, an actual recording position of recording information is specified based on the reproduction start time information and end time information (refer to FIG. 3) of each defined cell UD contained in the object recording sequence information OSI.
In this manner, the specified object OBJ is reproduced in order of the defined cells UD specified in each of setting reproduction sequence information UDI (step 25).
Next, it is checked whether or not reproduction of the last defined cell UD described in the setting reproduction sequence information UDI that corresponds to the currently reproduced object OBJ has terminated (step S26). When the result of the check is affirmative (step S26. YES), reproduction of the reproduction list is terminated intact. When the result of the check is negative (step S26: NO), processing returns to the step S25 at which reproduction processing is continued.
Next, reproduction processing based on the integrated reproduction list GL according to the present invention, which uses reproduction processing based on the reproduction list shown in FIG. 12, will be described with reference to FIG. 13.
In reproduction processing employing the integrated reproduction list GL, as shown in FIG. 13, the integrated reproduction list GL having the manner to be reproduced is first selected at the operating portion 15 (step S30). Next, the recording position of the selected integrated reproduction list GL is specified by referring to the integrated reproduction list start address information (refer to reference numerals 66 to 68 shown in FIG. 9) (step S31). Then, the number and type of the reproduction list stored in the corresponding integrated reproduction list GL are acquired (step S32).
Each of information (refer to reference numeral 53 shown in FIG. 7, for example) concerning the reproduction list is acquired from the setting reproduction sequence information UDI containing the reproduction list acquired at the step S32 (step 33) At the step S33, processing of the reproduction list shown in FIG. 12 is actually executed.
Next, as in the processing shown in FIG. 12, each defined cell UD is reproduced (step S34). Further, it is checked whether or not the reproduction of the last defined cell UD in the currently reproduced setting reproduction sequence information UDI is terminated (step S35).
When the reproduction is not terminated (step S35. NO), processing returns to the step S34 at which reproduction is continued. When reproduction of the last defined cell UD is terminated (step S35: YES), it is checked whether or not reproduction is terminated in accordance with the last reproduction list in the currently reproduced integrated reproduction list GL (for example, third reproduction list 69D exemplified in FIG. 9) (step S36).
In this way, when reproduction is terminated in accordance with the last reproduction list (step S36: YES), reproduction processing is terminated intact. When the reproduction is not terminated (step S36: NO), processing returns to the step S33 at which next reproduction list information is acquired, and the above reproduction processing is continued.
As has been described above, according to the embodied integrated reproduction list, the integrated reproduction list GL for sequentially reproducing two or more kinds of recording information is recorded in the DVD 1′, so that different kinds of recording information can be sequentially reproduced across the boundary in accordance with desired reproduction procedures.
In addition, the integrated reproduction list GL indicates the corresponding reproduction list by means of a pointer so that a desired reproduction list can be reliably specified and reproduced.
Further, each reproduction list is intended for reproducing each of the recording information in accordance with procedures that differs from the recording procedures when each of recording information is recorded, so that each of the recording information can be sequentially reproduced in the user desired manner.
Furthermore, each of the recording information is either the video information or the audio information, so that the video information and audio information can be reproduced all together.

In the above described embodiments, there has been described a case in which the integrated reproduction list GL is formed by employing the reproduction list of each of the recording information that has been already recorded on the DVD 1′, However, the present invention is applicable to a case of newly reproducing and acquiring a reproduction list that is not recorded on the DVD 1′.
In recording processing of the integrated reproduction list GL of the modified embodiment, as shown in FIG. 14, it is determined whether or not the integrated reproduction list is instructed to be formed at the operating portion 15 (step S10). When the result of the determination is negative (step S10; NO), processing is terminated intact. When the result of the determination is affirmative (step S10: YES), the reproduction portion of a reproduction list to be reproduced by employing the integrated reproduction list GL is specified at the operating portion 15 (step S11).
Next, it is checked whether or not the specified reproduction portion exists in a reproduction list (setting reproduction sequence information UDI) that has been already recorded on the DVD 1 (step S12). When the result of the check is affirmative (step S12: YES), processing goes to the step S14.

When it is determined that the integrated reproduction list GL has been generated at the step S15 (step S15: YES), a new reproduction list stored in the memory (not shown) is recorded in the setting reproduction sequence information UDI concerning the corresponding recording information (step 16). Further, the generated integrated reproduction list GL is recorded in the integrated navigation information area GNA in the DVD 1′ (step S17), and processing is terminated.
According to the modified recording processing described above, when a desired reproduction list as an integrated reproduction list GL does not exist on the DVD 1′, a required reproduction list is newly generated, and the integrated reproduction list GL is generated. Thus, the integrated reproduction list GL can be further generated and recorded so as to be reproduced in accordance with the more freely determined reproduction procedures.
