Embodiment

Embodiments of the invention are described with reference to the accompanying drawings.Following explanation is used for embodiment, wherein, the present invention is used to an information reproducing device, this device can (i) normal playback as the musical works that is recorded in the message unit on the DVD that is exclusively used in KARAOKE, (ii) in advance a plurality of musical workss be scheduled to and (iii) according to the order of being scheduled to these musical workss of resetting.

(I) embodiment of DVD

At first, before an embodiment of explanation information reproducing device of the present invention, illustrate that a kind of form and a kind of logical organization and a kind of work of a DVD, this DVD are used among the embodiment and comprise video information and the recorded information of audio-frequency information is recorded thereon referring to figs. 1 through Fig. 3.

At first, use Fig. 1 that a kind of record format of the recorded information on the DVD is described, this recorded information comprises video information and audio-frequency information (comprising music information).

As shown in Figure 1, a DVD 1 as a carrier has an introducing district LI and partly has a draw-out area LO at its most peripheral in its interior circumferential portion, video information and audio-frequency information are recorded in therebetween, so that they are divided into a plurality of VTS 3, each VTS 3 has a unique ID (sign) number (that is VTS#1 to VTS#n).

At this, VTS (video title set) 3 is one group of (bag) title (each all is a product or works that author or producer plan to offer spectators), they are relevant each other (for example, the attribute that is included in audio-frequency information in the title and image subsection information (that is, for example the information of the image subsection of caption) is identical as numbering, explanation, corresponding language etc.).More particularly, film is identical but a plurality of films that language that dub is different can be recorded as different titles respectively, and perhaps, even under the situation of identical film, the arenas version can be recorded as different titles respectively with specific version.

As shown in Figure 1, write down a Video Manager 2 in the front in VTS 3 residing zones.As the information that is recorded in this Video Manager 2, for example, write down be recorded in DVD 1 on all videos information relevant with audio-frequency information, for example be used to enter the menu of each title; Be used to prevent the information of bootlegging; Be used for directly entering the access list of each title, or the like.

Each VTS 3 is recorded into it and is divided into a plurality of VOB (object video) 10, each have ID numbering (VOB#1, VOB#2 ...), and have the control data 11 that is arranged on VOB 10 fronts.

At this, as shown in Figure 1, data that are made of a plurality of VOB 10 partly are confirmed as a VOB group (VOBS).Determine this VOB group so that a part that constitutes VTS 3 is used as the VOB 10 of the substantial portion of video and audio-frequency information and distinguishes mutually with the control data 11 of another part of formation VTS 3.

In the control data 11 of the front that is recorded in VTS 3, writing down for example information of PGCI (program chain information), this information is and resembles by a plurality of elements (should " element " will be described in detail later) being made up the relevant various information of a program chain the logical gate that obtains.

In each VOB 10, except control information, also write down the substantial portion of video and audio-frequency information (that is, video and audio-frequency information itself rather than control information).

And then a VOB 10 is made of a plurality of elements 20, each all have ID numbering (element ID#1, element ID#2 ...).

At this, a VOB 10 is constituted as by a plurality of element 20 and is finished, and an element 20 is not crossed over two VOB 10.

Then, VOB 10 is made of a plurality of VOB elements (VOBU) 30, its each all have an ID numbering (element VOBU#1, element VOBU#2 ...).

At this, VOB 30 is message units, and each all comprises video information, audio-frequency information and image subsection information.

A VOB 30 comprises: a navigation bag 41, the control information that is used for storing its controlling object that is included in VOB 30 and is video data etc.; Video data 42 as video information; A voice data 43 and a sub-image data 44 as image subsection information as audio-frequency information.At the moment, video data 42, voice data 43 and sub-image data 44 all are called the performance data.

At this, as video data 42, only having write down video is pictorial data.As voice data 43, only having write down audio frequency is voice data.And then, as sub-image data 44, only write down graph data for example as a character and a figure of image subsection.

By the standard declaration defined of DVD: on DVD 1, can write down 8 kinds of audio frequency, on DVD 1, can write down 32 seed images.

And writing task carries out like this: the playback duration length corresponding with a VOB unit 30 (that is, and be recorded in a navigation bag 41 and next navigation wrap the corresponding playback duration length of data between 41) is between 0.4 to 1 second.At this, why being no less than 0.4 second reason with a VOB unit 30 corresponding these playback duration length is in order to reduce the memory capacity of memory buffer, this memory buffer is called as PCI (expression control information, presentation control information) impact damper in following information reproducing device.Be that permissible time delay of the length that is used for decoding processing in Video Decoder is defined as 1 second with the no more than 1 second reason of a VOB unit 30 corresponding these playback duration length why, this is by the prescribed by standard of MPEG2 (Moving Experts Group 2) method (being compressed and being recorded as basis with video information of being write down etc. on DVD 1).Therefore, navigation bag 41 is always once detected every 0.4 to 1 second at playback time.

And then, on the beginning position of a VOB unit 30, always there is navigation bag 41.On the other hand, can not have video data 42, voice data 43 and sub-image data 44 simultaneously in a VOB unit 30, perhaps, even exist simultaneously under the situation of these bags in a VOB unit 30, the quantity of bag and the order of bag can freely determine.

At this, the discrimination unit separately of video data 42 shown in Figure 1, voice data 43 and sub-image data 44 is called as a bag P.Just, in a VOB unit 30, video data 42, voice data 43 and sub-image data 44 are divided into bag P respectively and are recorded in wherein.The bag P that is recorded in the video data 42 is called as a video packets.The bag that is recorded in the voice data 43 is called as an audio pack.The bag that is recorded in the sub-image data 44 is called as the frame image bag.

And then, in the bag stem that is recorded in each bag P beginning, write down and be called as reading the start time of SCR (system clock reference), this reads the time that the bright memory buffer that begins from following information reproducing device of playback time countershaft subscript in the middle of the start time reads in the data that comprise among each bag P.Each parcel that is further segmented by bag P comes recording video data 42, voice data 43 and sub-image data 44 as a record cell.In the DVD 1 of present embodiment, a bag P generally can be made of a parcel.

At last, navigation bag 41 has: a DSI (data search information) data 51, these DSI data 51 comprise the search information (specifically, writing down video or the residing address of audio frequency that search information for example will show or carry out voice output on DVD 1) of wishing to show or carry out a video image or an audio sound of voice output in order to search for; With a PCI (performance control information) data 50, with an information that shows that control is relevant, its information with DSI data 51 was that the basis is searched for when this pci data 50 was included in display video image or output audio sound.At this moment, DSI data 51 and pci data 50 constitute a DSI parcel respectively and a PCI parcel is used as parcel group PT and is carried out record.

And then all are included in a video data among the VOBU 30 and are made up of a GOP group (group of picture) at least.

In pci data 50, comprise high brightness information, from option, select one spectators and determine that one shows or work when selecting order.For example, by high brightness information, be provided with particular image platform (being so-called menu image platform) and go up the change of the relevant visual platform demonstration of selected option and the display position that will change at an option, select for spectators, and be provided with and the corresponding instruction of this option (that is the corresponding instruction that will carry out) with this option.

In sub-image data 44, writing down the video information that is used to constitute and show a frame, a selector button etc., need constitute and display menu image platform with it as image subsection information.

And then above-mentioned GOP is a minimum image cell, and it can independently be reset and be determined by the standard based on MPEG 2 methods.In the present embodiment, these MPEG 2 methods are a kind of being suitable for the video information recording image compression method of the time to the DVD 1.In the front of each GOP, writing down and reset to show temporal information, it is called as PTS (the performance time marking) and at the bright playback duration that is used for being presented at the included video data 42 of relevant GOP of playback time countershaft subscript.

At this, the overview of MPEG 2 methods has been described.That is, in general, in the successive frame image, the front of a frame image and the frame image of back often are similar mutually and have common relation.MPEG 2 methods are a kind of such methods: this point is paid attention in suggestion, the interpolation based on motion vector etc. by raw image is calculated, be transmitted and they are divided into several or several frames mutually in time on the basis at a plurality of frame images, be present in a frame image between a plurality of frame images.In the case, if this frame image will be recorded, only write down just enough with respect to the information of a difference vector of a plurality of frame images and a motion vector so that at playback time this frame image of resetting, this frame image is by setting up from a plurality of frame images corresponding to these vectors.Thus, this packed record can be realized this image.

And then the scheme of foregoing description GOP illustrates with reference to Fig. 2.Fig. 2 has represented to constitute the example of a plurality of frame images of a GOP.In Fig. 2, the situation that GOP 52 is made up of 12 frames (in MPEG 2 methods, the quantity that is included in a frame image among the GOP52 is not fixed) has been described as an example.In these frame images, be called as I image (intraframe coding image) by the represented frame image of label " I ", be defined as and can be used as the frame image that a complete frame image is reset by using its oneself picture information.Be called as P image (predictive coded image) by the represented frame image of label " P ", be defined on the I image of having decoded or other visual bases the frame image of decoding and predicting or take place by the difference of the predictive image that a quilt compensated and reset.Be called as B image (bi-directional predictive coding image) by the represented frame image of label " B ", be defined as by use the I image decoded or P image and in time will with relevant B image corresponding be recorded in the frame image that I image on the CD or P image are predicted or reset.In Fig. 2, represent the relation (that is, relation in compensation) of each image in prediction with arrow.

MPEG 2 methods of using in the DVD 1 of present embodiment have been utilized a kind of variable bit rate method, and wherein, the data volume that comprises in each GOP is not constant.Promptly, each image that comprises in a GOP 52 is corresponding with a motion video, and its movement velocity is quite fast and each mutual relationship between visual is smaller, in the case, constituting each visual data volume increases, and the data volume that comprises in a GOP 52 is also increased.On the other hand, each image that comprises in a GOP 52 is corresponding with a motion video, and its movement velocity is quite slow and each mutual relationship between visual is bigger, in the case, constitute each visual data volume and reduce, and the data volume that comprises in a GOP 52 is also reduced.

In the record format with sandwich construction shown in 1, each level is divided and can freely be provided with according to author's intention so that on the basis of the level of these settings executive logging.Reset by on the basis of the logical organization described later that is used for each division, carrying out, just can carry out diversified playback.

Below, illustrate by by the information that physical division write down shown in Figure 1 being made up a kind of logical format (logical organization) that is constituted with reference to Fig. 3.In fact this information be not that the logical organization with Fig. 3 is recorded on the DVD 1.But as an alternative, the information by in logical organization shown in Figure 3, they being made up each data that (especially element 20 being made up) reset shown in Figure 1 (for example, access information or temporal information) be recorded on the DVD 1, especially be recorded in the control data 11.

In order more clearly to describe, lower level describes from Fig. 3.Intention by a plurality of elements 20 in the physical arrangement of selecting and be used in combination Fig. 1 explanation according to the author logically constitutes a program 60.

This program 60 also is the logical block of a minimum, and its level is divided and can be confirmed by the system controller of following replay device, and can be by using an instruction to carry out access by system controller.

For the author, also can be defined as a minimum unit to the set of one or more programs 60, can also select to watch or listen to that it is called as PTT (ParT of Title) by spectators' freedom.Usually, this PTT can be called as chapters and sections.

Because by selecting a plurality of elements 20 logically to constitute a program 60, a plurality of programs 60 can be used an element jointly, promptly carry out " selecting to use " of so-called element 20, wherein, an element 20 is reset in a plurality of different programs 60.

At this, for the quantity of each element 20, on physical format shown in Figure 1, to treat in the element 20, its quantity is looked at as element ID numbering (indicating with element ID#) in Fig. 1.On the other hand, treat on logical format shown in Figure 3 in the element 20, its quantity is looked at as the element numbering by the order of describing among the following PGCI.

Then, by making up a plurality of programs 60, logically constitute a PGC (program chain) 61 according to author's intention.Above-mentioned PGCI (program chain information) is defined by the unit of PGC 61.This PGCI comprises information indication: the playback order of each program 60 in each program 60 of playback (according to this playback order, give each program 60 specify a unique program number (#1, #2 ...); Address as each element 20 of the record position on the DVD 1; Element numbering at the element 20 of the beginning of a program 60 will at first resetting; The playback method that is used for each program 60 is { for the author, can select a kind of playback method to be used as at the employed playback method of playback time from following method: (i) random playback is (by the random playback of using random number to carry out, and identical program 60 can repeatedly be reset), (it is a random playback of using random number to be carried out by with the method identical with random playback (ii) to upset playback, but a program 60 is only reset once rather than is reset repeatedly), (iii) circulation reset (it is the playback of repeatedly resetting a PGC 61) and (iv) circulation reset with random playback or upset the combination of playback; And various navigation instructions (for example, for each program 60 and each element 20, the author specifies the instruction of playback order etc. can for the playback of above-mentioned performance data (for example video data 42, voice data 43 and sub-image data 44), and it is called as " navigation instruction " below).

The record position of PGCI on the DVD 1 can resemble and be in (referring to Fig. 1) in the control data 11 above-mentioned, perhaps be in the control data (not shown) in the Video Manager 2, if suitable substance P GCI and menu relevant (referring to Fig. 1) in the Video Manager 2.

In PGC 61, comprise that the video of essence and voice data etc. are used as the combination (in other words, the combination of element 20) rather than the above-mentioned PGCI of program 60.

And, in a PGC 61, as illustrated before explanation, can carry out the selection utilization (that is, identical element 20 is by a plurality of different PGC 61 common utilizations of using) of element 20 for program 60.

Because the method for playback element 20 is used, except with in the recording channel on DVD 1 with record reset in proper order element 20 method (promptly, the method of resetting the continuous element of arranging) outside, the author can also select a kind of with the order of record sequence independence on DVD 1 reset element 20 method (promptly, the method of the element of the discontinuous layout of resetting, for example, the method for the element 20 of first playback of recorded on the recording channel of back).

Like this, title 62 in logic by one or more PGC 61 (PGC#1, PGC#2 ...) constitute.For example, this title 62 is the unit corresponding to a film, and is that the author is desirable to provide the complete information to the spectators of DVD1.At this, comprise the above-mentioned PTT of a title 62 for each, to be included in the additional PTT numbering of order on this title 62 (below be called PTTN).

At last, VTS 63 in logic by one or more title 62 (title #1, title #2 ...).The title 62 that is included among this VTS 63 has identical attribute mutually.For example, same film of different language is corresponding to separately title 62.

The information among the VTS 63 shown in Figure 3 of being included in is corresponding to the information that is included among the VTS 3 shown in Figure 1.That is, all information that are included among the logic VTS shown in Figure 3 63 are registered as a VTS 3 in DVD shown in Figure 11.

In Video Manager shown in Figure 12, comprised video manager information, this video manager information comprises that search information (search pointer) is to search for each title 62 etc.And then, in this video manager information, comprised the table information that is referred to as a Title Search Pointer Table.In this Title Search Pointer Table, comprise (i) Title Search Pointer Table information, the numbering of wherein having described the title search pointer (promptly, the numbering of included title 62 in DVD 1), (ii) title search pointer (to the title search pointer of each title) has wherein been described the PTT (each comprises one or more programs 60) that is included in each title 62.

Because the author specifies on the DVD 1 with the physical arrangement divided information according to the logical format of foregoing description, has then formed the title of watching for spectators (for example, film images).

At this, above-mentioned video manager information, PGCI, pci data 50 and DSI data 51 are commonly referred to as navigation data, and it is as the playback control information.

The group of being made up of a plurality of PGC 61 of title 62 of being used to reset is called as one " Title area ", and it has been reset by the VOBS that uses the title that comprises in VTS 63.A group that is used for a plurality of PGC 61 of replayed menus or message is called as " Video Manager area ", and it has been reset by the VOBS that uses the menu in the Video Manager 2.A group that is used for a plurality of PGC 61 of replayed menus is called as " video title set menu area ", and it is included in the VOBS of the menu among the VTS 63 by use and has been reset.Above-mentioned video manager menu zone and above-mentioned video title set menu area are commonly referred to as one " menu area ".

And then an empty PGC 61 who writes down for the PGC61 that is inserted in the following information reproducing device as DVD 1 time decision and is at first reset is called as one " at first play area ".

The Overall Steps owing to predetermined playback of present embodiment at first, is described with reference to Fig. 7.

As shown in Figure 7, in owing to predetermined playback, at first the primary power of discriminant information replay device is (the step S1) that connects or cut off.If (the step S1: be) that cut off, processing leaves it at that.If not (the step S1: not), then judge a kind of interrecord structure (that is the sandwich construction of the recorded information of DVD 1) (step S2) of the musical works that on DVD 1, is write down that cuts off.For example, in this step S2, judge each musical works be recorded on the DVD 1 record whether like this: title 62 or title 62 corresponding with musical works is made of a plurality of program 60, and each program 60 only comprises a musical works.Thus, judge whether the prearranged signals Sr from operating unit 75 has indicated title 62 or program 60.

Then, judge whether that order begins to reset and imported owing to predetermined playback (step S3) from operating unit 75.If it is transfused to (step S3: be), begin to carry out (step S4) by the playback of the indicated musical works of this order, and workflow enters into step S5.

On the other hand, (step S3: not), workflow does not enter into step S5 because predetermined playback is transfused to if order begins to reset.

Then, at step S5, the predetermined key that is not illustrated by operating operation unit 75, numerical key etc. are specified the predetermined musical works that will reset, and the playback of musical works that should be predetermined begins to carry out, if there are not other titles reset (step S5) at this moment.

Then, judge whether to cancel this predetermined operation and whether be transfused to operating unit 75.If this cancellation operation is transfused to, this predetermined being cancelled.If the cancellation operation is not transfused to, (step S6) carried out in this playback continuously.

Then, if because predetermined playback is not performed, the playback of the musical works that has begun in step S4 is carried out continuously.If, handles according to the search that is used for the predetermined music works that describes in detail below and search for next scheduled musical works (referring to Figure 12), and the playback of this next one musical works begins (step S7) because predetermined playback is performed.

Below, with reference to Fig. 8 to Figure 12 detailed process in each step in the master routine shown in Figure 7 is described continuously.

At first, come among the description of step S2 deterministic process with reference to Fig. 8 to the sandwich construction of the recorded information among the DVD1.

As shown in Figure 8, in deterministic process, judge at first whether DVD 1 is replaced (step S10) to the sandwich construction of recorded information.(step S10: not), owing to do not need to change the sandwich construction of the recorded information among the DVD 1 that has judged, then workflow enters step S3 (returning) if do not change.On the contrary, if it has been replaced (step S10: be),, then need read the various control datas (step S11) on the DVD 1 owing to must rejudge the sandwich construction of recorded information.In the various control datas of in this step, being read, comprise above-mentioned Video Manager 2.At this moment, description is read in the system controller 74 as the Title Search Pointer Table at the numbering place of the title search pointer of the numbering that is recorded in the title 62 on the DVD 1 with to the title search pointer that each title 62 is described the numbering place of the chapters and sections that write down.

Then, whether the numbering of judging the title 62 confirmed equals or exceeds " 6 " (step S12).If equal or exceed " 6 " (step S12: be), the numeral of importing by the numerical key of operating unit 75 is confirmed to be the numbering of indicating this title 62, above-mentioned numeral is included among the prearranged signals Sr that is input to thereafter in the system controller 74, and workflow enters next procedure S3 (returning).

On the other hand, by the judgement among the step S12, if the numbering of title 62 is less than " 6 " (step S12: not), whether the maximal value of judging the numbering (being the numbering of the chapters and sections of each title 62) of the next chapters and sections that are identified (=PTT can illustrate identical thing below) is equal to, or greater than " 6 " (step S13).If the numbering of chapters and sections is less than " 6 " (step S13: not), workflow enters step S14, is confirmed to be the numbering of expression title 62 in this numeral of importing by the numerical key of operating unit 75, and and then enters step S3 (returning).

By the judgement among this step S13, if the maximal value of the numbering of chapters and sections is equal to or greater than " 6 " (step S13: be), the numeral of importing by the numerical key of operating unit 75 is confirmed to be the numbering (step S15) of indicating these chapters and sections, above-mentioned numeral is included among the prearranged signals Sr that is input to thereafter in the system controller 74, and workflow enters next procedure S3 (returning).

The meaning (being the numbering of confirmation form indicating topic 62 or chapters and sections 60) of the implication of confirming the numbering imported by numerical key from step S12 to step S15 then, is described in above-mentioned processing with reference to Fig. 4 B.

As described above, under the situation of the DVD 1 that is exclusively used in KARAOKE, a title 62 only is made of a musical works usually.But a title 62 can be made of each combination that comprises a plurality of chapters and sections 60 of a musical works.

Promptly, shown in Fig. 4 B like that, if be equal to, or greater than " 6 ", each title 62 only is made of a musical works, if and in these titles 62, only comprise a title 62 of forming by two chapters and sections, because the major part of title 62 only is made of a musical works respectively, in the predetermined or search of playback time, be preferably in the numeral that the numeral of importing by numerical key from viewpoint affirmation easily in the playback procedure is the numbering of expression title 62 thus.

On the other hand, even the numbering of title 62 is less than " 6 ", only there is a title 62 to form by each a spot of chapters and sections that only the constitute chapters and sections of (promptly less than " 6 ") by a musical works, it is confirmed to be the DVD 1 that is exclusively used in KARAOKE, wherein, even the musical works that is write down is quite a lot of, a title 62 is corresponding to a musical works.Like this, under these circumstances, in the predetermined and search of the unit of using musical works, preferably the numeral of also importing by numerical key from viewpoint affirmation easily is to represent the numeral of the numbering of title 62.

Thereby, in the processing of step S2, if the numbering of title 62 is equal to, or greater than " 6 " (step S12: be), because DVD 1 is assumed to be the DVD 1 that is exclusively used in KARAOKE, wherein have many each musical workss that write down corresponding to a title 62, the numeral of importing by numerical key is confirmed to be the numeral (step S14) of the numbering of expression title 62.

On the other hand, if the numbering of title 62 is less than " 6 " (step S12: not), if and the maximal value of the numbering of the chapters and sections 60 of each title 62 is less than " 6 " (step S13: not), because DVD 1 is assumed to be the DVD 1 that is exclusively used in KARAOKE, several each musical works that write down corresponding to a title 62 are wherein only arranged, and the numeral of importing by numerical key is confirmed to be the numeral (step S14) of the numbering of expression title 62.

And then, if the numbering of title 62 less than " 6 " (step S12: not) and if the maximal value of the numbering of the chapters and sections 60 of each title 62 be equal to, or greater than " 6 " (step S13: be), because DVD 1 is assumed to be the DVD 1 that is exclusively used in KARAOKE, wherein have many each musical workss that write down corresponding to a title 62, the numeral of importing by numerical key is confirmed to be the numeral (step S15) of the numbering of expression chapters and sections 60.

Employed threshold value " 6 " is the value that the quantity according to the general musical works on the DVD 1 of record KARAOKE musical works decides in step S12 and step S13.

Among Fig. 8 in step S12 and step S13 employed threshold value be not limited in this value " 6 ".For example, can use any natural number between 5 to 10 as this threshold value.

Come predetermined implementation among the description of step S5 below with reference to Fig. 9 and Figure 10.

As shown in Figure 9, in predetermined implementation, at first, judge in operating unit 75, to have operated to be used to start the predetermined key (step S40) that predetermined input is handled.If (step S40: not), workflow enters step S6 (returning) because the processing of the predetermined replay of present embodiment is not performed then in not operation.Otherwise if predetermined key has been operated (step S40: be), information reproducing device S is set under the predetermined input mode (step S41).Like this, import the musical works (step S42) that to reset owing to be scheduled to by operating unit 75.

In this step S42, more specifically, represent the title identifier or the numbering of section of musical works that will be scheduled by the numerical key input.If title identifier of being imported or the numbering of section imported are really as the title identifier among the DVD 1 or numbering of section and exist, then this title identifier imported or numbering of section are stored in ending place of the predetermined music works inventory in the storer of not representing, and, the input that is used for next predetermined music is accepted, and so repeats.

When the end of input of the musical works that is used to be scheduled to (step S42), the musical works of being imported is according to predetermined order reset (step S43).The details of this operation in step step S43 will be described later.

Then, when predetermined being performed, the predetermined input mode that has been set up in step S41 is cancelled (step S44), and workflow enters next procedure S6 (returning).

The process of resetting predetermined musical works in step S43 is described below with reference to Figure 10.

As shown in Figure 10, in predetermined implementation, at first, judge whether information reproducing device S is set under the predetermined executive mode (step S50).If be under the predetermined executive mode (step S50: be), workflow enters step step S44 (returning).On the other hand, (step S50: not), the working method of information reproducing device is switched under the predetermined executive mode (step S51) under the predetermined executive mode if not being in.Then, judge (I) whether resetting title 62 or chapters and sections 60 or (ii) this playback whether finish or suspend (step S52).If this playback finishes or suspend (step S52: be), workflow enters step S54 so that start because predetermined playback.On the other hand, if reset (step S52: not), zone (for example menu area) (step S53) except that above-mentioned Title area judges whether to reset.

Then, reset that (step S53: not), workflow enters step S44 (returning) if in above-mentioned steps S4 or following step S54, begun the Title area of the playback carried out.On the other hand, if reset in the zone except that above-mentioned Title area (step S53: be), this playback is stopped, and first predetermined musical works on the predetermined music works inventory of search in storer on the DVD 1, so that start because predetermined playback (step S54), and workflow enters step S44 (returning).

Suitable speech, even have only when being under an embargo but under the situation that the search carried out owing to the interruption of playback after suspending is allowed to, the search that is used for the predetermined music works is activated at step S54 under the situation that in detected navigation data ND, allows this search or when search.At this moment, if search and stop all to be under an embargo just can not be carried out because the playback of being scheduled to.Therefore, cancelled predetermined executive mode under these circumstances.

Come predetermined cancellation process among the description of step S6 below with reference to Figure 11, at first, judge whether information reproducing device S is set under the predetermined executive mode (step S60).(step S60: not), because information reproducing device S carries out normal a playback, then workflow enters step S7 (returning) under the predetermined executive mode if not being arranged on.On the other hand, if be arranged under the predetermined executive mode (step S60: be), whether the not clear key of expression of decision operation unit 75 (being used for order cancellation because predetermined playback) is operated (step S61).If this clear key is operated (step S61: be), because because predetermined playback will finish, workflow enters step S69, is cancelled in this predetermined executive mode, and then enters step S7 (returning).

By the judgement of step S61, (step S61: not), whether the not stop key of expression of decision operation unit 75 is operated (step S62) if clear key is not operated.If stop key is operated (step S62: be), because because predetermined playback will finish, workflow enters step S69, and then enters step S7 (returning).

On the other hand, judgement by step S62, if stop key is not operated (step S62: not), judge that whether the assorted cold dishes list is shown (step S63) by the not operation of the Menu key of expression of operating unit 75, this assorted cold dishes list is a kind of menu information that is included in the above-mentioned menu area, and, this assorted cold dishes list is the menu on the DVD 1 of being recorded in that removes outside the menu that is stored in advance among the information reproducing device S (for example, not being recorded under the situation on the DVD 1 or at employed menu under the situation that various settings are carried out with respect to information reproducing device S at this menu information).If the assorted cold dishes list is shown (step S63: be), because because predetermined playback will finish, workflow enters step S69, and then enters step S7 (returning).

On the other hand, by the judgement of step S63, (step S63: not), whether judgement is present mode (step S64) to the predetermined of each chapters and sections if assorted cold dishes Dan Wei is shown.If (step S64: not), workflow enters step S67 should predeterminedly to represent present mode.Otherwise, be present mode (step S64: be) if be somebody's turn to do predetermined, judge according to an operation in the operating unit 75 whether a chapter search (that is the detection of the beginning of each chapters and sections) is performed (step S65).If this chapter search is performed (step S65: be), workflow enters step S69, and owing to upcoming being cancelled to each musical works enters step S7 (returning).

On the other hand, by the judgement of step S63, if assorted cold dishes Dan Wei is shown (step S63: not), judge predetermined whether carrying out (the step S64) to each chapters and sections.(step S64: not), workflow enters step S67 if should predetermined not carry out.Otherwise,, judge whether to carry out a chapter search (that is the detection of the beginning of each chapters and sections) (step S65) according to an operation of operating unit 75 if should predetermined carry out (step S64: be).If this chapter search is performed (step S65: be).Workflow enters step S69, owing to the upcoming cancellation to each musical works enters step S7 (returning).

Then, by the judgement of step S65, if chapter search is not performed (step S65: not), judge whether that the navigation instruction that detects the playback of issuing another chapters and sections in the title of resetting from DVD 1 is used as navigation data ND (step S66).If this navigation instruction is detected (step S66: be), this predetermined executive mode is cancelled, so that carry out the playback (step S69) that has reflected the musical works of the author's of institute's playback of recorded information intention among the DVD 1.Then, workflow enters step S7 (returning).On the other hand, if do not detect navigation instruction (the step S66: not) of the playback of issuing another chapters and sections, { it is that a search to each title is handled to judge whether to carry out title search, in more detail, be search (that is, the detection of the beginning of each title) to the beginning of each title, and owing to read the next stage existing problems in advance, then under the recorded information situation that for example role participates in playing etc., it can be forbidden by navigation data ND } (step S67).If this title search is performed (step S67: be), because because of predetermined playback will finish, then workflow enters next procedure S7 (returning) by step S69.

On the other hand, judgement by step S67, if title search is not performed (step S67: not), judge whether to detect the navigation instruction of the playback of issuing another title except that the title that comprises these chapters and sections and as navigation data ND (step S68), these chapters and sections are reset because of predetermined from DVD 1.If it is detected (step S68: be), predetermined executive mode is cancelled, so that carry out the playback (step S69) that has reflected the musical works of the author's of institute's playback of recorded information intention among the DVD 1.Then, workflow enters step S7 (returning).On the other hand, if do not detect the navigation instruction (step S68: not) of the playback of issuing another title, workflow enters step S7, so that carry out the playback (returning) be scheduled to continuously.

Suitable speech, in the processing of step S69 shown in Figure 11, after predetermined executive mode is cancelled, carry out the processing of resetting according to the navigation data ND that is reset from DVD 1 with normal mode.

At last, come the search of the musical works that is used to be scheduled among the description of step S7 to handle with reference to Figure 12.
