Embodiment

(first embodiment)

The following describes first embodiment about recording medium of the present invention.The recording medium that relates to present embodiment is a kind of rewritable DVD (following abbreviation " DVD "), can write down mobile pictorial data thereon according to the DVD-Video record standard.Fig. 1 has shown DVD1 and the pen recorder 100 that relates to present embodiment.100 pairs of broadcasted contents by the broadcast singal of terrestrial antenna 101 and parabola antenna 102 receptions of pen recorder are encoded, and the broadcasted content that is encoded is write DVD1.DVD1 is a kind of DVD of multi-user's compatibility, is shared by two users that show among the figure (user A and user B).

DVD1 has the layer structure that comprises Physical layer, file system layer, application layer etc., and the data of digital stream form by pen recorder 100 records thereon.

Fig. 2 has shown the structure (file structure) by the DVD1 on the file system layer of dotted arrow indication.In the file structure that shows in Fig. 2, DVD_RTAV (real time record audio frequency and video) catalogue is positioned at the next stage under the root directory, and the management document of having stored the AV file of several TS-VOB and having stored various types of management information is positioned under the DVD_RTAV catalogue.TS-VOB (transport stream-video object) is the data that are recorded with the transport stream form, and its VOB with the program flow form is different.The digital stream of mentioning in " claim " and the application's " summary of the invention " just is meant this TS-VOB.

Fig. 3 has shown the structure that arrives level in detail of the TS-VOB that is stored in the AV file.In the drawings, the AV file that shows among Fig. 2 is presented at as on first degree the 7th grade.Being stored in TS-VOB in the AV file is presented among Fig. 3 the 6th grade.As shown in FIG., TS-VOB obtains by being multiplexed in the video flowing and the audio stream that show on the first order.The video flowing that is positioned on the first order is multiple bar chart image data (" pi1 ", " pi2 ", " pi3 " ...) a sequence.In these pictorial data each was shown in a display cycle (being also referred to as " frame of video ").Under situation about showing with the NTSC form, a frame of video is similar to has 33 milliseconds (accurately, 1/29.97 seconds).Under situation about showing with the PAL form, a frame of video has 40 milliseconds.These pictorial data are compressed by the coding based on the correlativity between the frame.Correspondingly, the multiple bar chart image data that constitutes video flowing can be classified into 3 types image, just, use and an image of resetting on the direction in the past and " B (bi-directional predicted) image " that compresses with the correlativity of the image that will on following direction, reset, use " P (prediction) image " that compresses with the correlativity of an image of resetting on the direction in the past and do not use correlativity but " I (inside) image " that the spatial frequency characteristic corresponding to a frame in the use image is compressed.

In video flowing, the least unit of decoding is referred to as " GOP (group of picture) ".A GOP comprises at least one I image, and is the set with the multiple bar chart image data in the playback duration cycle that is similar to 1.0 seconds.In Fig. 3, the video flowing shown in the first order is divided into a plurality of GOP on the second level.The coded format that is used for pictorial data is the coded format of variable-length, so data length is according to each GOP and difference.When data are recorded in DVD when going up, the GOP sequence is divided into a plurality of parts and does not consider the size of each GOP.Separated part is stored in the PES packet sequence shown in the third level.On the other hand, the audio stream that is positioned at the right side of the first order also is divided into a plurality of parts, and separated part is stored in the PES packet sequence that shows on the third level.Shown in the third level among the figure, the divided portion of PES bag store video stream and the divided portion of audio stream.At the head end of each PES bag, with " PTS " of the decoded result that shows " DTS " that separate section will decoded sequential and demonstration separate section with the sequential that is shown.

The PES packet sequence of storage GOP sequence and the PES packet sequence of storing audio stream are by multiplexed (" tj1 " among the figure), thus the TS packet sequence shown in the formation fourth stage.Formed VOBU (Video Object Unit) shown in level V with at least one GOP with the multiplexed voice data of multiple bar chart image data.VOBU is the minimum unit that is used for access TS-VOB, and it forms by the video packets and the audio pack of arranging by the mpeg standard definition.TS-VOB shown in the 6th grade has a plurality of VOBU with the time series structure arranged.Provided description so far about the inner structure of TS-VOB.

The 3rd to the division shown in the level V and multiplexed be the distinctive feature of TS-VOB, in the DVD of routine, can't see.VOB to be recorded on conventional DVD, promptly the VOB of program flow form consists of a plurality of packets, and a PES bag directly is stored as each bag.On the other hand, for the TS-VOB of transport stream form, PES is stored as the TS bag after wrapping in and being divided into a plurality of parts.Fig. 4 has shown how the PES bag is stored as the TS bag.

Shown in the third level among Fig. 4, the TS bag is made up of TS packet header end, application field and service load.The size of TS bag is 188 bytes.The size of data of 188 bytes is big or small identical with the ATM bag that transmits on the ATM transmission path.The size of TS bag determines like this, makes that the TS bag can be with the bag that transmits by the ATM transmission path by record directly.

The service load storage is by dividing the separate section that the PES bag obtains.When PES bag was video flowing a part of, this service load was corresponding to video layer.In Fig. 4, the PES bag shown in the first order is divided into a plurality of parts shown in the second level, and each separate section is stored in the service load of the TS bag shown in the third level, shown in arrow " ct1 ", " ct2 " and " ct3 ".

The structure of TS packet header end is indicated by dotted arrow " hg1 ".Shown in arrow " hg1 ", end storage in TS packet header is used to discern the video flowing under this TS bag or " PID (Packet Identifier) " of the audio stream under this TS bag, and " Payload Unit begins indicator " that be used in reference to the starting position that is shown in the service load this PES bag, and be used for indicating application field whether to follow " application field control " after this TS packet header end of this TS bag.

When a separate section of video flowing was stored in the service load, " application field " storage was about the information of the system layer of video flowing." hg2 " is indicated as dotted arrow, and this information about system layer comprises " PCR (program clock benchmark) " and " random access indicator ".PCR is the reference value of the reference clock " STC (system time clock) " of the convection current equipment of decoding.This reference value is used to the processing that (1) multichannel is decomposed a transport stream, and (2) use transport stream to rebuild the processing of various PES streams (for example video flowing).Whether the PES bag in " random access indicator " expression service load comprises first frame of the access point of video flowing.Access point is present in the stream, and is the unit that can be decoded alone, and the random access indicator represents whether first frame (I image) of GOP exists.

Provided description so far about difference between the VOB of TS-VOB and program flow form.How the following describes TS-VOB is recorded on the DVD.A DVD comprises a plurality of ECC pieces, and the ECC piece is the posting field that mistake can be corrected.The a plurality of TS bags that constitute a transport stream are converted into the unit that is called as " capsule ", and are recorded into the ECC piece.Capsule forms by arranging a plurality of TS bags that have ATS attached to it respectively.ATS (sign time of arrival) is the information that enters the sequential of this device about the TS bag.

The following describes the inner structure of management document.Fig. 5 has shown the inner structure of management document." fs0 " is indicated as dotted arrow among the figure, management document by many vob informations (VOB#1 information, VOB#2 information, VOB#3 information ...) and many PGC information (PGC#1 information, PGC#2 information, PGC#3 information ...) form.

The content of the expansion control that will carry out when playback time is that to skip a CM district and this expansions control be unified when effective for a plurality of playback paths, the district that extend property district detecting unit 12 specifies the shown a plurality of playback paths execution expansions of many playback path information that will serve as reasons therein as shown in figure 11 to control uniformly.In order to realize that this unification specifies, extend property district detecting unit 12 produces district's marker character of the position in an extend property district that specifies the quilt appointment uniformly among the TS-VOB, and should distinguish marker character and be arranged in the vob information.Here, district's marker character produces in the following manner.Extend property district detecting unit 12 monitors the attribute of the signaling zone that constitutes digital broadcast signal and analog broadcast signal.When finding that an attribute changes, the position that extend property district detecting unit 12 detects corresponding to this change on the TS-VOB.It is contemplated that, such change be expand position that control will begin, promptly in the starting point in an extend property district.Therefore, can produce the district marker character of this detected change position, and this district's marker character is set in the vob information as an extend property district of appointment of starting point.In order to produce district's marker character, extend property district detecting unit 12 adopts to be attached to detect to be input to the PTS that the PES in scrambler 7 and the extraction unit 10 wraps when attribute changes or to be attached to when detecting attribute and changing the PTS that wraps from the PES of scrambler 7 and extraction unit 10 outputs represents to change the position.

In extend property district detecting unit 12, has CM district detecting unit 13.When a signaling zone with stereo audio attribute was inserted in the broadcast singal with monophonic audio attribute, CM district detecting unit 13 detected on the digital streams position corresponding to the change from the analogue audio frequency to the stereo audio.It is contemplated that detected change position is to skip place that the expansion control in CM district will begin, promptly have a starting point in the extend property district of attribute " CM ".Therefore, produce district's marker character of specifying an extend property district as starting point, and this district's marker character is set in the vob information with this change position.

Finish when TS-VOB write DVD, playback path information generation unit 14 selects to constitute a starting point as a unit in the TS bag of TS-VOB, and selects to constitute another terminal point as this unit in the TS bag of TS-VOB.Then, playback path information generation unit 14 produces a unit information, and this unit information has a PTS and has a PTS to come respectively as origin information and endpoint information unit in that terminal point is subsidiary in that starting point is subsidiary.By producing many unit informations and arrange many unit informations that produced in storer, playback path information generation unit 14 obtains playback path information, and produces the PGC information that comprises the playback path information that is obtained subsequently.Here should be noted that for a user-defined playback path starting point of unit and terminal point are to operate according to the user who is received by user interface section 2 to select.

Record control unit 15 realizes writing control with the buffering of mark road impact damper 5 as prerequisite.This is write to be controlled to be and waits for that mark road impact damper 5 is full of by the TS bag from demoder 7 or extraction unit 9 outputs, and, when mark road impact damper 5 is full of by the TS bag, some the TS bags in the mark road impact damper 5 are write the ECC piece of DVD.When providing the user who stops to write down and operate, the TS of accumulation bag is written in the ECC piece of DVD in the mark road impact damper 5, and the vob information and the PGC information that are stored in the residence memory 4 are written to DVD.Then, recording process finishes.

Provided explanation so far about the parts of the recording process that is used for realizing pen recorder 100.The parts of the playback procedure that is used for pen recorder 100 are described below.Such parts comprise that demoder 16, playback control module 17, extend property district are provided with unit 18 and viewing area detecting unit 19 not.

Demoder 16 comprises demultiplex unit (1), Video Decoder (2) and audio decoder (3).Demultiplex unit (1) will resolve into video data sequences and audio data sequence from the VOBU multichannel that DVD reads by driving arrangement 3.Video Decoder (2) is to video data decoding.Audio decoder (3) is decoded to voice data.Demoder 16 will output on the TV as the AV signal of the multiplex signal of video and audio frequency.

Playback control module 17 carries out indirect referencing by using access graph as master meter, calculates the address that the TS as a unit starting point on the DVD wraps.Equally, playback control module 17 calculates the address of the TS bag of the terminal point that is used as a unit on the DVD by identical indirect referencing.After the address that has calculated corresponding to the TS bag of the starting point of the unit on the DVD and terminal point, playback control module 17 instruction driving arrangements 3 read the TS bag that is present between these addresses, and the TS bag that 16 pairs of instruction decoders are read is decoded.By many unit informations that constitute playback path information being carried out this playback control, can realize playback control according to playback path information.Here should be noted that above-mentioned playback is controlled to be basic control.By reading VOBU brokenly, pen recorder 100 also can be realized special playback.For example, skip some VOBU simultaneously by reading a plurality of VOBU, rather than all TS bags of resetting, can realize fast forward playback.Equally, by reading a plurality of VOBU, can realize fast reverse playback according to the order that wraps in the reversed in order of arranging among the TS-VOB with TS.

When the content of the expansion that will carry out at playback time control is the not viewing area etc. of resetting, and expand control only to the playback path that is shown by a playback path information when effective, it wherein will be that playback path is carried out and expanded the not viewing area of controlling that the extend property district is provided with that unit 18 specifies individually.In order to realize so independent appointment, can produce district's marker character of specifying the position in this district, and it is arranged in the PGC information.District's marker character can produce in the following manner.The extend property district is provided with unit 18 and detects the user's operation that provides at the playback control period of carrying out based on playback path.When detecting a user and operate, the position that detects this user's operation on digital stream is considered to will begin to expand the position of control.Produce an appointment with the district marker character of detected position, and it is arranged in the PGC information as the extend property district of starting point.In order to produce district's marker character, the extend property district is provided with unit 18 and uses to be attached to detect and be input to the PTS that the PES in the demoder 16 wraps when the user operates, and represents detected position.

Viewing area detecting unit 19 is not arranged in the extend property district unit 18 is set.Viewing area detecting unit 19 does not detect user's operation at the playback control period of carrying out based on playback path.When detecting an operation that stops to reset, the position that detects this operation on digital stream is considered to will begin to expand the position of control.Produce an appointment with detected position as starting point and with the terminal point of playback path district's marker character as the extend property district of terminal point, and it is arranged in the PGC information.The function of viewing area detecting unit 19 is not to detect a not viewing area.Therefore, when the playback of playback path was begun or stopped by the user, viewing area detecting unit 19 did not just detect an extend property district at every turn, and produced district's marker character of specifying this extend property district.In the present embodiment, the extend property district of being detected by viewing area detecting unit not 19 is not " a playing " district, but one " not watching " district, meaning promptly comprises the district outside the district of being reset by the user.Here suppose user's recorded program when watching broadcast program, and when stopping to watch, continue record.Under such a case, from the position that the user stops to watch, arrive the district of the end of playback path, be detected as a not viewing area.For example, when user's recorded program and when when stopping to watch, continuing record when watching broadcast program, viewing area detecting unit 19 can not detect one and stops the operation that the user watches, for example cut off the operation of TV power supply, and can be a not viewing area the district's detection that begins from the position that detects this operation to TS-VOB finishes.

Provided explanation so far about the parts of pen recorder 100.These parts are computer implemented by program and decoding and this program of execution.Figure 14 and 15 is the process flow diagrams that show the process of this program.Further describe the processing of carrying out by pen recorder 100 below with reference to these process flow diagrams.For easy explanation, hereinafter hypothesis only detects CM district and viewing area not, and only the CM district and not the viewing area be set to the extend property district.

In process flow diagram shown in Figure 14, the cyclic process of being made up of to S3 step S1 is positioned at the superiors of operating process.This cyclic process is to be used for according to user's operation corresponding parts being distributed in processing.When the user who provides an opening entry process operates, detect this user's operation by user interface section 2, operating process moves on to step S4 from step S3.At step S4, record control unit 15 detect an analog broadcast signal signaling zone audio attribute and it is stored as the default audio attribute.In addition, record control unit 15 is reset to " 0 " with a sign that will be described later.In step S5, the signaling zone coding that 7 pairs of record control unit 15 command encoders are imported one by one, operating process moves on to a cyclic process of being made up of step S6 and S7 then.This cyclic process be used for making CM district detecting unit 13 analog broadcast signal continuously input during in the change of audio attribute in detection signal district.The judged result of this cyclic process in step S7 finishes when becoming "Yes".In addition, during change in the audio attribute that at every turn detects signaling zone, the operating process after having carried out the operating process of step S8 in the S14 among repeating step S6 and the S7.Step S8 is to make detecting unit 13 detected change positions in CM district be set to the beginning or end in extend property district to the operating process among the S14.Step S8 was provided with beginning or end in S14 after, the cyclic process of being made up of step S6 and S7 was returned in operating process.More specifically, when analog broadcast signal is imported continuously and continued recording process, when change that at every turn detects in the audio attribute, the beginning or end in an extend property district is set by CM district detecting unit 13.At step S9 and S12, CM district detecting unit 13 detects and is input to the PTS that the TS in the scrambler 7 wraps when the audio attribute that is attached to analog broadcast signal is changed.The change position of audio attribute is represented by this PTS.The starting point and the switching between the terminal point that change the position are set can be realized by using a sign.When the value of this sign was " 0 ", CM district detecting unit 13 was in the detected PTS of step S10 be set to the to have attribute starting point in extend property district of " CM ".Then, CM district detecting unit 13 is set to " 1 " at this sign of step S11.When the value of this sign was " 1 ", CM district detecting unit 13 was at the detected PTS of step S13 be set to the to have attribute terminal point in extend property district of " CM ".Then, CM district detecting unit 13 is reset to sign " 0 " at step S14.

When providing a user who stops recording process and operate, operating process moves on to step S16 from step S7.At step S16, record control unit 15 generation in residence memory 4 wherein be provided with the position of specifying extend property district with attribute " CM " district's marker character vob information and comprise the PGC information of the playback path information that shows the default playback path among the TS-VOB.At step S17, record control unit 15 is write DVD with vob information and PGC information.

Provided explanation so far about recording process.Utilize above-mentioned recording process, TS-VOB, vob information and PGC information are recorded on the DVD.

When the user who provides an execution playback procedure operated, operating process moved on to the cyclic process of being made up of to S22 the step S18 shown in Figure 15 from the cyclic process of being made up of to S3 step S1.The cyclic process of being made up of to S22 step S18 is to receive the various user's operations that are used for user-defined playback path information.When the user who provides an execution normal playback operates (step S18: be), playback control module 17 instruction driving arrangements 3 are carried out the dish visit that is used for normal playback in step S18.Consequently, the playback of video of TS-VOB is displayed on the TV.When the user who provides an execution fast forward playback or fast reverse playback operates (step S19: be), record control unit 15 instruction driving arrangements 3 are carried out the dish visit that is used to realize fast forward playback or fast reverse playback in step S24.Utilize the aforesaid operations process, can under high speed, realize the visit of the beginning of a part being set to the unit.When the user who provides a designating unit starting point operates (step S20: be), playback path information generation unit 14 detects and is attached to the PTS that wraps from the TS of demoder 16 outputs in step S25, and detected PTS is set to the starting point of unit information.On the other hand, when providing the operation of a designating unit terminal point (step S21: be), playback path information generation unit 14 detects and is attached to the PTS that wraps from the TS of demoder 16 outputs in step S26, and detected PTS is set to the terminal point of unit information.By repeating the aforesaid operations process, many unit informations that constitute playback path information in residence memory 4, have been produced.When providing an operation that stops playback procedure, the judged result among the step S22 becomes "Yes".Then, in step S15, playback path information generation unit 14 will comprise that the PGC information of the playback path information that forms by many unit informations that arrange to produce writes on the DVD.

Playback procedure based on the TS-VOB of user-defined playback path information and executing is described below.User-defined playback path information is made up of many unit informations, therefore, discern (being called as " j unit information ") by use variable " j " through the active cell information of the operating process of step S27 in the S33.Use variable " j " as its control variable by the cyclic process that step S27 forms to S30.Playback control module 17 is from user-defined j unit information of playback path information acquisition (step S28), and instruction driving arrangement 3 reads the VOBU (step S29) between the origin-to-destination that is present in this j unit information.16 couples of VOBU that read of demoder decode, so that output video.Control variable increases progressively in step S31.When judging that in step S30 control variable finishes when arriving unit total, when judging that perhaps having provided a user that will stop to reset operates, this cyclic process finishes.

When providing the user that will stop to reset and operate, operating process moves on to step S32 from step S30.At step S32, viewing area detecting unit 19 does not produce district's marker character, this district's marker character begins the position after an adjacent TS bag that in the end is input to the demoder in unit " j ", to the district of the terminal point of the last unit information that is positioned at playback path information, be appointed as the have attribute extend property district of " not watching ".Then, viewing area detecting unit 19 district's marker character that will produce in step S33 is not arranged in the user-defined PGC information.Utilize the aforesaid operations process, for user-defined playback path being provided with has the extend property district that attribute " is not watched ".

According to aforesaid present embodiment, have the pen recorder 100 of constructing described in the present embodiment and make that the DVD that describes can be produced in first embodiment, and therefore can promote the extensive of in first embodiment, describing of DVD to popularize.

(the 3rd embodiment)

Present embodiment has been described when having extend property district that attribute " do not watch " by being arranged on district's marker character in the PGC information when specified, the position of how to specify this extend property district on DVD.The access graph that is included in the vob information connects the size of playback duration cycle and each VOBU.Therefore, write on the address and the summation in playback duration cycle in the access graph, can discern the VOBU that a VOBU and who comprises extend property district starting point comprises extend property district terminal point by calculating.When the starting point in extend property district and terminal point are included in the same unit, comprise the VOBU of starting point and comprise the VOBU of terminal point and the VOBU that is present between these two VOBU can be read simply.Here, when starting point and terminal point were included in the different unit, it is complicated that processing will become.Figure 16 A has shown that the starting point in an extend property district and terminal point are included in the example in two continuous unit (unit #1 and unit #2) respectively.In this case, for the unit #1 of front, the VOBU that is present between the terminal point " rp2 " of the starting point " rp1 " in extend property district and unit #1 will be read.For the unit #2 of back, the VOBU that is present between the terminal point " rp4 " in the starting point " rp3 " of unit #2 and extend property district will be read.More specifically, when the extend property district comprises two borders (borders between two unit in terminal point that comprises the extend property district respectively and starting point) between the unit, the starting point that is present in the extend property district at first is read to the VOBU between the terminal point of the unit of front, then, read the starting point of the unit that is present in the back to the VOBU between the terminal point in extend property district.In other words, reading of VOBU will be performed twice.Figure 16 B shown the starting point in an extend property district and terminal point be included in respectively in three or more the continuous unit first with last unit (unit #1 and unit #5) in example.In this case, for first unit #1, the VOBU that is present between the terminal point " rp6 " of the starting point " rp5 " in extend property district and unit #1 will be read.For last unit #5, the VOBU that is present between the terminal point " rp8 " in the starting point " rp7 " of unit #5 and extend property district will be read.For being clipped in unit #2 in the middle of unit #1 and the unit #5 to unit #4, all VOBU that are present between the origin-to-destination of each unit will be read.By reading unit #1 is to unit #5 in the above described manner, the VOBU that is included in the extend property district can be read.

According to aforesaid present embodiment, though in the position in an extend property district by " to the indirect referencing of indirect referencing " when represented, the initial sum final position of the TS-VOB that reset also can easily be specified.

(the 4th embodiment)

Present embodiment discloses processing performed in the time all will carrying out at one time based on the expansion control that is arranged on the district's marker character in the PGC information and based on the expansion control that is arranged on the district's marker character in the vob information.Figure 17 has shown the inner structure of the playback control module 17 that relates to present embodiment.Playback control module 17 in the present embodiment comprises that expanding control execution unit 20 controls adjustment unit 21 with expanding.

Expand control execution unit 20 in, or in by the expansion controlled attribute district that is arranged at the district's marker character appointment in the PGC information, carry out the expansion control unique this extend property district by the expansion controlled attribute district that is arranged at the district's marker character appointment in the vob information.

Expanding control adjustment unit 21 carries out adjustment processes and solves conflict between the expansion control in the lap that might betide two extend property districts.Will be by expanding adjustment process that control adjustment unit 21 carries out based on the extend property in extend property district, priority of expansion control setting for will in each extend property district, carrying out, and carry out the expansion control with high priority exceptionally and do not carry out the expansion control with low priority.

Figure 18 has shown a not overlapping situation of a part and an extend property district with attribute " CM " (a CM district) of viewing area.In this case, expansion control adjustment unit 21 is carried out the adjustment between the expansion control that will carry out in the following manner in these two extend property districts.When as the extend property district of viewing area not with as the extend property district in CM district when overlapped, expand the expansion control setting priority that control adjustment unit 21 is controlled and will be carried out for the expansion that will carry out in the CM district in viewing area not.When being higher than the priority that is provided with for expansion control " skipping the CM district " for the priority that expands control " the not viewing area of resetting " setting, lap in these two extend property districts, execution is by the expansion control " skipping the CM district " of arrow " cy1 " expression, rather than expansion control " the not viewing area of resetting ".On the other hand, for not with the part of the not viewing area of CM area overlapping, indicated as arrow " cy2 " and " cy3 ", carry out the not expansion control of viewing area of resetting.Describe below and how priority to be set for each extend property district.In the present embodiment, the priority by the extend property district of the district's marker character appointment in the vob information is set to be higher than the priority by the extend property district of the district's marker character appointment in the PGC information, and its reason is as follows.Be based on user's operation and definition by the extend property district of the district's marker character appointment in the PGC information, so its content usually is that the user is distinctive.On the other hand, the extend property district by the district's marker character appointment in the vob information usually has general value for all users.With the distinctive expansion control of user is compared, this expansion control that has a general value for all users is given higher priority, thereby realizes expanding the coordination of control.

When the control of the expansion in the overlapping extend property district conflicted each other, this adjustment of being undertaken by expansion control adjustment unit 21 in the lap in extend property district necessitated.When the control of the expansion in the overlapping extend property district can be executed in parallel, this adjustment of expanding control adjustment unit 21 then was unnecessary.For example, when the expansion control that will carry out in the CM district does not conflict with the expansion control that will carry out in other overlapping extend property districts, the content of controlling just as the expansion in the CM district is in the time of will showing the thumbnail image of a URL or show label in the CM district, and the expansion control in the CM district can be carried out concurrently with the expansion control in other extend property districts.By distinguishing the classification information of marker character, expand control adjustment unit 21 and also can judge to expand control whether can executed in parallel (that is, whether adjustment is necessary) with reference to each.

Expanding control adjustment unit 21 is made up of the program of the process flow diagram of a realization as shown in Figure 19 and 20 and the processor of this program of decoding and carry out.Figure 19 and 20 is the process flow diagrams that show the operating process of the expansion control adjustment unit 21 that relates to present embodiment.According to this process flow diagram, carry out and to reset not that the expansion control of viewing area is general rule.Yet,, carry out the exception processing of skipping this CM district when one not when viewing area and a CM area overlapping.For easy explanation, hypothesis only detects CM district and viewing area and they are set are the extend property district not below.

In step S40, comprise have attribute " not watching " the extend property district starting point unit " i " and comprise that the unit " j " of the terminal point in this extend property district is identified.Then, operating process moves on to step S41.In step S41, carry out the judgement of whether mating about unit " i " and unit " j ".Unit " i " and unit " j " coupling mean that the viewing area is not included in the unit.

When unit " i " and unit " j " mates, in step S43, has the extend property district that attribute " is not watched " from its origin-to-destination playback unit " i ".Here, should be borne in mind that this not the viewing area may with a CM area overlapping.Step S42 is used for judging whether the extend property district is overlapping.When the starting point in a CM district was included in not in the viewing area, the playback of viewing area was not stopped exceptionally in the starting point in this CM district, and recovers at the terminal point in CM district.More specifically, in step S44, carry out to adjacent position before the starting point in extend property district from adjacent position after starting point and to reset with attribute " CM " with extend property district that attribute " do not watch ".Then, at step S45,, carry out to terminal point and to reset with extend property district that attribute " do not watch " from adjacent position after the terminal point in extend property district with attribute " CM ".When above-mentioned playback control was finished, the operating process in the process flow diagram finished.

On the other hand, as unit " i " and unit " j " when not matching, the starting point with extend property district that attribute " do not watch " in step S47 in unit " i " is carried out to the terminal point of unit " i " and to be reset.Then, at step S48, the unit after the adjacent active cell in sequence is set to unit " i ".Should remember that, when one not when viewing area and a CM area overlapping, step S47 and S48 also carry out the processing of exception here.Step S46 is used for judging whether carrying out this exception and handles.At step S46, carry out whether comprise a starting point with extend property district of attribute " CM " about unit " i ".When unit " i " comprises the starting point in CM district, will carry out exception and handle.This exception handle mainly be playback unit " i " before the CM district and part afterwards, also be the playback corresponding to the part in CM district of skipping unit " i ".

More specifically, in step S49, carry out to adjacent position before the starting point in CM district from the position after the adjacent starting point in viewing area not reset after, comprise a unit of CM district terminal point in step S50 identification.Here, identification comprises that this unit of CM district terminal point is because comprise that the unit of terminal point may not match with unit " i ".Here, the unit that comprises the terminal point in CM district is set to unit " k ".In step S51, the unit that is set to unit " k " is re-set as unit " i ".By being re-set as unit " i ", can skip the unit that is present between unit " i " and " k " in this unit that will be set to unit " k ".At last, at step S52, to the not playback of the terminal point of viewing area, the exception processing finishes from adjacent position after the terminal point in CM district in execution.

When finishing dealing with among step S48 and the S52, operating process moves on to a cyclic process of being made up of to S56 the step S53 shown in Figure 20.In this cyclic process, with the variable " i " of unit " i " as control variable.In step S55, reset by the unit (=unit " i ") of variable " i " identification.When the judged result among the step S53 became "Yes", this cyclic process finished.At step S53, carry out terminal point about extend property district and whether be included in judgement in the unit " i " with attribute " CM ".When the judged result in step S53 was "Yes", this cyclic process finished, and operating process moves on to step S57.

Step S54 is used for when the starting point in CM district is included in unit " i ", switches to exception from normal process and handles.When carrying out exception and handle, do not make variable " i " increase progressively 1, but skip those unit before the unit of a terminal point that comprises the CM district.More specifically, in step S61, carry out playback from the starting point of unit " i " to adjacent position before the starting point in CM district.Then, in step S62, identification comprises the unit " k " of the terminal point in CM district.In step S63, the unit that has been set to unit " k " is re-set as unit " i ".Also have such situation: unit when skipping many unit " i " may comprise the not terminal point of viewing area.Whether step S64 is used for judging unit " i " is to comprise the not unit of viewing area terminal point.More specifically, in step S64, carry out about unit " i " whether comprise terminal point with extend property district that attribute " do not watch ".Unit " i " is judged as and comprises that this terminal point means that then above-mentioned cyclic process will finish.Therefore, do not wait until always that the judged result among the step S53 becomes "Yes", in step S66, carry out to the terminal point of viewing area not and reset that operating process finishes then from adjacent position after the terminal point in CM district.

When unit " i " is determined when not comprising terminal point, in step S65 from adjacent position after the terminal point in CM district to the unit terminal point of " i " carry out and reset, then, the cyclic process of being made up of to S56 step S53 is returned in operating process.By repeating this cyclic process, do not comprise not reset in the viewing area one by one in the unit of CM district terminal point.

When the cyclic process of being made up of to S56 step S53 finished, operating process moved on to step S57.Step S57 is used for judging and comprises whether the unit of the terminal point of viewing area not comprises the starting point in the extend property district with attribute " CM ".When judgement comprised that the unit of the terminal point of viewing area does not comprise the starting point in CM district, the starting point of " i " was carried out to the terminal point of viewing area not and is reset from the unit in step S58.

When judgement comprises that the unit of the terminal point of viewing area does not comprise the starting point in CM district, starting point from unit " i " in step S59 is carried out playback to adjacent position after the terminal point in CM district, then, in step S60, carry out to the terminal point of viewing area not and reset from adjacent position after the terminal point in CM district.

According to aforesaid present embodiment, satisfy each individual consumer's the expansion control of watching hobby and can advantageously be merged for the expansion control that a plurality of users have a general value.Therefore, can increase the variation of resetting in controlling.

(the 5th embodiment)

Present embodiment relates to segmentation (segmentation) and detailed description (elaboration) the corresponding improvement that is used for district's marker character.For playback path, being used for Attribute Recognition is that the benchmark of an extend property is very different according to each fabricator's of pen recorder 100 consideration and business strategy.Therefore wish that further segmentation and detailed description can appear in the district's marker character that appointment is had the district of such extend property.Present embodiment discloses a DVD that can advantageously manage this district's marker character that is segmented and describe in detail eventually.

Figure 21 has shown the PGC information that relates to present embodiment and the inner structure of vob information.The difference of district's marker character of describing among the district's marker character among the figure and first embodiment is that it also has " classification information ".The classification information that newly provides in the present embodiment shows that this district's marker character is to belong to wherein to distinguish marker character for the effective classification of a plurality of fabricators, still belongs to wherein to distinguish marker character only to an effective classification of fabricator.Figure 22 has shown the content of this classification information.Marker character belongs to when wherein distinguishing marker character for the effective classification of a plurality of fabricators when the district, and classification information shows " code that the fabricator is shared ".When district's marker character belongs to when wherein distinguishing marker character only to the effective classification of fabricator, classification information shows " code unique to the fabricator " and is used to discern this fabricator " fabricator ID ".

District's marker character effectively means following situation to a plurality of fabricators.Be used to discern of a plurality of fabricator approvals of the benchmark in the extend property district corresponding by this participation dish standard with this district's marker character.And, also approve pen recorder 100 by these fabricators' manufacturings of this dish standard of participation, in extend property district, carry out the expansion control shared to these fabricators by this district's marker character appointment.

District's marker character only effectively means following situation to a fabricator.The benchmark that is used to discern the extend property district corresponding with this district's marker character is definite separately by a fabricator of this dish standard of participation.The pen recorder 100 that approval is made by other fabricators that participate in this dish standard need not carried out in the extend property district by this district's marker character appointment and expand control.In the later case, district's marker character need be identified the fabricator that it becomes effective pen recorder 100, therefore, comprises above-mentioned fabricator ID in classification information.

At playback time, pen recorder 100 is consulted included fabricator ID in vob information or district's marker character of being provided with in PGC information.When district's marker character only effectively and during the fabricator ID coupling of the fabricator ID that finds and pen recorder 100, pen recorder 100 is carried out to expand based on this district's marker character and controlled to a fabricator.When district's marker character only effectively and the fabricator ID of the fabricator ID that finds and pen recorder 100 when not matching to a fabricator, pen recorder 100 is not carried out based on the expansion of this district's marker character and is controlled.

The inner structure of the pen recorder 100 that relates to present embodiment is described below.Figure 23 has shown the inner structure of the pen recorder 100 that relates to present embodiment.The pen recorder 100 that relates to present embodiment is also to have a fabricator ID with the difference that relates to the pen recorder 100 of front embodiment and preserves unit 23, and record control unit 15 and playback control module 17 can be carried out the distinctive processing of present embodiment.

Fabricator ID preserves unit 23 and preserves the identifier unique to the fabricator of pen recorder 100.

Record control unit 15 is when producing district's marker character, and judgement is by the type of the extend property in the extend property district of this district's marker character appointment.Record control unit 15 produces the classification information that shows judged result then.More specifically, record control unit 15 judges that the extend property districts are to a plurality of fabricators effectively or only effective to a fabricator.When judging the extend property district only to a fabricator when effective, record control unit 15 is provided with the fabricator ID that is preserved unit 23 preservations by fabricator ID in classification information.

Expand control in order to carry out, playback control module 17 is consulted district's marker character of specifying the extend property district.When the classification information that is arranged in district's marker character shows this district marker character for a plurality of fabricators when effective, playback control module 17 is carried out being controlled by the unique expansion in the extend property district of district's marker character appointment.When the classification information viewing area marker character that is arranged in district's marker character only to a fabricator when effective, playback control module 17 obtains the fabricator ID that comprises in district's marker character, and with the fabricator ID that obtains with preserve the fabricator ID that preserves unit 23 by fabricator ID and compare.When two fabricator ID couplings, playback control module 17 is carried out in by the extend property district of district's marker character appointment and is expanded control.When fabricator ID did not match, playback control module 17 was not carried out and is expanded control.

According to aforesaid present embodiment,, fabricator's fabricator ID is set in district's marker character for only a fabricator effectively being distinguished marker character.Therefore, by consulting the fabricator ID of district in the marker character, can therefore be implemented in playback time and ignore district's marker character by the unique setting of other fabricators.Like this, can avoid by based on other fabricators the benchmark of unique setting and the processing carried out, the faulty operation that is caused.

(the 6th embodiment)

Present embodiment relates to the improvement under long-time executive logging data conditions on the DVD that simultaneously has 27G byte or more recording capacity.On such high capacity DVD, under the situation of NTSC broadcasting, can write down 13 hours or longer broadcasted content.Along with the appearance of this DVD, can be recorded in the form of a TS-VOB on the DVD at the program of in half a day or a day, broadcasting on the specific channel.Then, wish that such DVD can have multi-user's compatibility, make a large number of users that comprises kinsfolk and friend to enjoy the enjoyment of watching these programs by sharing this DVD.Yet under such a case, each user need find among the TS-VOB corresponding to the program of broadcasting in half a day or a day by such as the special playback of fast forward playback, and he or she wants the program watched.Even consider recently high speed processing, find this operation of such program for each user, to remain unusual trouble to the fast forward playback of DVD.

Consider this point, it is an extend property district that the extend property district detecting unit 12 that relates to present embodiment detects the part corresponding to a program of TS-VOB, and produces district's marker character of specifying the extend property district of being detected in vob information.Figure 24 has shown the inner structure of the extend property district detecting unit 12 that relates to the 6th embodiment.As shown in the figure, except CM district detecting unit 13, extend property district detecting unit 12 comprises that also program sequence changes district's detecting unit 24 and race way detecting unit 25.

Program sequence changes district's detecting unit 24 with in the digital broadcast signal, and wherein to be changed that district's (such district is called as " program sequence changes the district ") for certain content detects be an extend property district to program sequence information.The detection that is changed 24 pairs of extend property districts of detecting unit, district by program sequence is based on PSI (program specific information: by the program sequence information of Moving Picture Experts Group-2 definition) and SI (information on services: the program sequence information that is defined by ARIB-STD B-10) carry out.PSI is the information that is used to define program sequence.The example of PSI comprises PAT and PMT.PMT is the information that is used to define the flow structure of broadcast program.More specifically, pmt table is shown in a plurality of streams of the transport stream that is multiplexed into the Polymera type, and which video flowing and audio stream constitute each broadcast program.Figure 25 A has shown the example of PMT.In the figure, form by video flowing with PID=001 and audio stream corresponding to the broadcast program of PMT#1 with PID=002.Pat table shows to be used to obtain each broadcast program that the form with the transport stream of Polymera type transmits with reference to which PMT.Figure 25 B has shown the example of PAT.In the figure, the flow structure of broadcast program #1 is defined by PMT#1, and the flow structure of broadcast program #2 is defined by PMT#2.On the broadcasting channel that receives by tuner, the ID of these PMT and PAT is consulted, and detects ID that mates predetermined value or the ID that is different from previous ID.Whereby, be identified as the extend property district, produce district's marker character of specifying this extend property district, and district's marker character that will produce be arranged in the PGC information corresponding to the district of a broadcast program among the TS-VOB.By being appointed as the extend property district, can advantageously carry out the expansion control that begins to conduct interviews of broadcast program or the expansion control of skips broadcast program corresponding to the district of a broadcast program among the TS-VOB.

Race way detecting unit 25 is with in the digital broadcast signal, and the district's detection that wherein sends the interactive broadcasting program is the extend property district.The detection of being undertaken by race way detecting unit 25 to the extend property district is to realize by detecting a district that wherein sends data with the datacycle form.Datacycle is a kind of broadcasting format that identical content is used to realize interactive broadcasting that repeats to send.The identical content of repeated broadcast comprises the BML document write as with BML (broadcast markup language) and by monomedia (mono media) data of BML document reference.The data that repeat to send with the datacycle form are divided into a plurality of parts, store in the piece that is called as " DDB (downloading data block) " and with the distinctive control information that is called as " DII (download message indication) " and send.DII was sent out before DBB.And the data length of DBB is written among the DII.Therefore, race way detecting unit 25 identifies an extend property district corresponding to the datacycle in the transport stream according to DII, produce district's marker character of specifying this extend property district, and district's marker character that will produce is arranged in the PGC information.By being appointed as the extend property district with the data block that the datacycle form sends, the expansion control of data block is controlled or is skipped in the expansion that can advantageously carry out the beginning of visit data piece.

According to aforesaid present embodiment, program sequence changes the change that district's detecting unit 24 detects in the program sequence information.When detecting the signaling zone with specific program sequence properties in digital broadcast signal, program sequence changes district's detecting unit 24 and produce district's marker character of specifying corresponding to the extend property district of this signaling zone in TS-VOB.Because this point, in the TS-VOB of the time span with half a day or a day, the position of each program can be represented roughly.Therefore, the position that is stored in each program in the AV file can be discerned roughly.If the position of program can be identified, then the beginning of this program of next time visit can comprise corresponding to the playback path in the district of this program by generation and advantageously carrying out.In this case, visit each user and want the beginning of the program watched can not take long to, therefore, even when a plurality of users want to watch the content that is recorded on the DVD, each user can not feel disappointed yet.

Though having described program sequence, present embodiment changes district's detecting unit 24 detects the position of program by the change among detection PSI and the SI situation; but consideration for copyright protection; program sequence changes the district that district's detecting unit 24 also can forbid having of a sponsored program district of the signal attribute reset or have a signal attribute of restriction record (only duplicate inferior) and is considered as the extend property district, and produces district's marker character of specifying this district.

Equally, in digital broadcast signal and analog broadcast signal, a signaling zone that comprises the EPG that shows specific style type, cast and title can be regarded as the extend property district, and can produce district's marker character of specifying such district in vob information.At playback time, can plant in the extend property district and carry out the expansion control that shows such stylistic category, cast and a title.

(the 7th embodiment)

Present embodiment discloses when the reformed district of program sequence information wherein or when wherein the district that is sent out with the datacycle form of data is detected as the extend property district, the expansion control that carry out in the extend property district.In the present embodiment, to expanding control execution unit 20 and expanding control adjustment unit 21 and made improvement.Describe below and expand control execution unit 20 and expand control adjustment unit 21.

When the extend property district is wherein when the reformed district of program sequence information (program sequence change district), expand control execution unit 20 and carry out and expand control, jump over to carry out by the playback of the beginning in the extend property district of district's marker character appointment.Having a kind of situation is, the program sequence informational needs is read in advance by replay device one end.In this case, carry out the playback control that playback that program sequence changes the beginning in district jumps over and be performed, read such program sequence information in advance so that guarantee replay device one end.When the extend property district be wherein data repeat to send with the datacycle form district (race way) time, expand control execution unit 20 and carry out and expand control, only to reset with one in send a plurality of of datacycle form or many data.More than illustrated by expanding the expansion control that control execution unit 20 is carried out.Describe below and expand control adjustment unit 21.

Expand control adjustment unit 21 carry out adjustment processes solve when the extend property district that changes district or race way as program sequence when having the extend property area overlapping that attribute " do not watch ", the conflict between the expansion that will carry out in the lap in extend property district is controlled.The expansion control that will carry out after expansion control adjustment unit 21 has been carried out adjustment process is described below.

Figure 26 A has shown that a program sequence changes district and one and do not overlap each other and change the situation that the distinctive expansion control in district conflicts each other to the distinctive expansion control in viewing area not with to program sequence in the viewing area.In this case, the starting point of viewing area " my1 " is not included in the program sequence change district.The distinctive expansion control in the viewing area not starting point that is viewing area never begun to carry out resets, under the normal condition of therefore resetting never the starting point of viewing area begin to carry out.Yet the starting point of viewing area " my1 " is not included in the program sequence change district.This means not viewing area and program sequence change area overlapping.Therefore, change the distinctive expansion control in district conflict each other to the distinctive expansion control in viewing area not with to program sequence.Here, when being higher than for the priority of the distinctive expansion control setting in viewing area not when changing the priority of the distinctive expansion control setting in district for program sequence, carry out distinctive expansion control exceptionally to program sequence change district, rather than to the not distinctive expansion control in viewing area.Shown in the arrow among Figure 26 A " ty1 ", playback point is backwards to the starting point in program sequence change district, and begins to carry out playback from the starting point " hc1 " in program sequence change district.

Figure 26 B has shown that a race way and one do not overlap each other and to the distinctive expansion control in viewing area not with to the distinctive expansion control in the race way situation of conflict each other the viewing area.The distinctive expansion control in the viewing area not starting point that is viewing area never begun to carry out reset.Expand control if carry out such one, be included in this and will do not reset in the whole circulation district in the viewing area.On the other hand, be in a plurality of data blocks one of resetting to the distinctive expansion in race way control.Therefore, to these two the distinctive expansion control in district conflicts each other.Here, when the priority that is higher than for the priority of the distinctive expansion control setting in race way for the distinctive expansion control setting in viewing area not, in the lap in these two districts, carry out exceptionally the distinctive expansion control in race way, rather than to the not distinctive expansion control in viewing area.Shown in arrow " sr1 ", in a plurality of data blocks of resetting one, and the not entire portion of viewing area of not resetting, and remaining data block will be skipped shown in arrow " sr2 ".

According to aforesaid present embodiment, when the not viewing area that the playback path that be each user is provided with changes area overlapping with race way or program sequence, carry out exceptionally to change and distinguish and the control of execution based on race way or program sequence.Therefore, can verily carry out based on processing by the control information of digital broadcast transmission.

(the 8th embodiment)

In a second embodiment, by the modulation broadcast ripple and select digital broadcast signal that channel obtains, promptly the digital broadcast signal corresponding to a single program is converted into a TS-VOB.Present embodiment relate to by the modulation broadcast ripple but do not select digital broadcast signal that channel obtains, promptly corresponding to the digital broadcast signal of a plurality of programs, convert the improvement under the situation of a TS-VOB to.This TS-VOB corresponding to a plurality of programs is called as " Polymera TS-VOB ", and the pen recorder 100 that relates to present embodiment has the record that can realize this Polymera TS-VOB and the structure of playback.Figure 27 has shown the inner structure of the pen recorder 100 that relates to present embodiment.In the drawings, some parts of pen recorder 100 do not show.As an alternative, the path with dashed lines arrow " ZS1 " of Polymera TS-VOB and " ZS2 " expression." ZS1 " is indicated as arrow, and the Polymera TS-VOB that reads to mark road impact damper 5 from DVD1 is output to digital tuner 8, and then, " ZS2 " is indicated as arrow, and Polymera TS-VOB outputs to record control unit 15 from digital tuner 8.In order to realize the transmission of Polymera TS-VOB on these paths, the figure generation unit 11, playback control module 17 and the extend property district detecting unit 12 that relate to present embodiment are made distinctive improvement.

Figure generation unit 11 produces an access graph, and does not analyze the TS head end and the application field of TS bag.More specifically, figure generation unit 11 reads when being attached to each predetermined time interval from digital tuner 8 and outputs to the ATS that the TS of extraction unit 9 wraps, and produces the inlet information that the ATS and the time interval are interrelated.By repeating to produce such inlet information, the figure generation unit has produced an access graph.

The Polymera TS-VOB of playback control module 17 reading and recording on DVD, and the Polymera TS-VOB that reads outputed to digital tuner 8, shown in arrow " ZS1 ".When digital tuner 8 is selected a channel, and output during corresponding to the digital broadcast signal of a single program, shown in arrow " zs2 ", be output to demoder 16 corresponding to the digital broadcast signal of this single program.The single program that is output to demoder 16 causes its channel to be output and to be shown by the broadcast program that digital tuner 8 is selected.

When the user who digital tuner 8 is provided a channel of selection operated, extend property district detecting unit 12 obtained to show the information of this channel of being selected by the user from digital tuner 8.When Polymera TS-VOB is output and is presented on the TV, and when providing a user who stops to reset subsequently and operating, to produce specify as district's marker character of the position in the extend property district of viewing area not, its mode is with described mode is identical in a second embodiment, then, the channel that obtains from user interface section 2 is set at district's marker character.As mentioned above, when write or read Polymera TS-VOB, do not analyze the TS head end and the application field of TS bag.The starting point and the terminal point that this means the extend property district can not be represented with PTS.Therefore, extend property district detecting unit 12 uses an ATS respectively, but not uses PTS, represents the starting point and the terminal point in extend property district.In this case, in being attached to the ATS that a plurality of TS wrap, the ATS when preferably using the most approaching use PTS represents the starting point and the terminal point in extend property district respectively.The example of such ATS is to be attached to the ATS that the TS that outputs to demoder 16 when the user who provides playback operates wraps.Figure 28 has shown district's marker character, is provided with by extend property district detecting unit 12 at this district's marker character intermediate frequency Taoist monastic name.

Utilize above-mentioned processing, can produce the district's marker character that comprises channel.By will distinguishing the processing that the channel that comprises in the marker character outputs to digital tuner 8 at playback time next time, the user does not need to carry out the operation of digital tuner 8 being selected channels at playback time next time.

Though present embodiment has only been described the situation that is arranged on the district's marker character in the PGC information, nothing it should be noted that identical deletion is handled and can be carried out on the district's marker character in being arranged on vob information.In other words, the extend property district can be partially removed together along with whole deletion or the part deletion of TS-VOB.

(the tenth embodiment)

Present embodiment relates to along with the editor who moves who relates to the unit that constitutes playback path who is carried out by pen recorder 100 (being called " moving editor "), the improvement under the situation that the extend property district is edited.Figure 50 has shown the inner structure of the pen recorder that relates to present embodiment.As shown in the figure, should note as parts of the pen recorder that relates to present embodiment and the mobile edit cell 27 that provides in addition.Mobile edit cell 27 is carried out the moving process that moves the unit that constitutes playback path.The moving process of being carried out by mobile edit cell 27 waits by update area marker character, unit information to be realized.

Figure 51 A and 51B have schematically shown at four unit #1 that constitute playback path in unit #4, unit #1 have been moved to the mobile editor of adjacent position after unit #3.Shown in Figure 51 A, this playback path has shown with unit #1, unit #2, unit #3 and the tactic sequence of unit #4.By mobile unit #1 indicated in arrow " mv0 ", become the order of unit #2, unit #3, unit #1 and unit #4 by the represented sequence of playback path.Playback path is made up of the sequence of a plurality of unit, and via the one or more positions of specifying the extend property district by indirect referencing in a plurality of unit.Because the form that the indirect referencing of district's marker character is taked depends on unit sequence, therefore when being changed by the unit sequence of indirect referencing, the extend property district seems also to be changed.Yet, the district's marker character starting point and terminal point of only specifying the extend property district, so the such change in the unit sequence usually only needs the change in the sequence of many unit informations.

More specifically, the extend property district is defined by the position that its starting point and terminal point are appointed as in the discrete cell.Therefore, comprise that those unit outside the discrete cell of the starting point in extend property district and terminal point can be moved freely, and to the extend property district without any influence.For example, a unit that comprises the entire portion in extend property district can be moved out of the extend property district, a unit outside the extend property district can be by shift-in extend property district, and perhaps a unit in the extend property district can be moved to a diverse location in the extend property district.Yet, comprise the unit of starting point and comprise that the unit of terminal point can not be moved freely, when such move the starting point that the terminal point that will cause the extend property district is positioned at the extend property district before the time.The reversed order of terminal point and starting point is represented the fault of the correctness aspect in extend property district.Therefore, in the time will moving a unit, carry out about this cell moving whether cause the terminal point in extend property district and the judgement that a dot sequency is reversed.When the order of judging terminal point and starting point was reversed, mobile edit cell 27 upgraded district's marker character of specifying the extend property district, so that prevent the above-mentioned fault of the correctness aspect in extend property district.

The process of above-mentioned fault that the update area marker character is used to prevent the correctness aspect in extend property district is described below.In the time will carrying out the mobile editor of a unit, at first carry out the judgement that whether comprises the beginning or end in extend property district about the unit that will be moved.When the unit that will be moved comprises starting point, carry out the unit that whether will cause comprising starting point and be positioned at the unit judgement afterwards that comprises terminal point about cell moving.When this judged result for certainly the time, mobile edit cell 27 upgrades the origin information of start element ID and district's marker character in such a way, makes the starting point in extend property district in adjacent position after the unit that will move.By doing like this, the marginal portion in extend property district is shortened, and can be avoided but starting point is positioned at the fault of the correctness aspect in terminal point extend property district afterwards.

Figure 51 C and 51D have shown the process that moves a unit of the starting point that comprises the extend property district.Unit #1 in the drawings is in unit #4, and unit #1 comprises the starting point in extend property district, and unit #3 comprises the terminal point in extend property district.Here hypothesis comprise the unit #1 of starting point such as arrow " my1 " indicated to be moved to position between unit #2 and the unit #3.In this case, because unit #1 is positioned at before the unit #3 of the terminal point that comprises the extend property district, therefore mobile edit cell 27 update area marker character not.

The process of update area marker character when Figure 52 A and 52B have shown unit that moves the starting point that comprises the extend property district.

Here hypothesis comprise the unit #1 of starting point such as arrow " my2 " indicated to be moved to position between unit #3 and the unit #4.In this case, because unit #1 is positioned at after the unit #3 of the terminal point that comprises the extend property district, move the fault of the correctness aspect that causes the extend property district so judge this.For fear of this fault, mobile edit cell 27 is the update area marker character in such a way, makes that the starting point in extend property district is the starting point of adjacent unit #2 after unit #1.

When the unit that will be moved comprises terminal point, carry out the unit that whether will cause comprising terminal point and be positioned at the unit judgement before that comprises starting point about cell moving.When this judged result for certainly the time, mobile edit cell 27 is updated into message breath and end unit ID in such a way, makes that the terminal point in extend property district is adjacent position before the unit that will move.By doing like this, the inlet information in extend property district is shortened, and can be avoided but terminal point is positioned at the fault of the correctness aspect in starting point extend property district before.

Figure 53 A and 53B have shown the process that moves a unit of the terminal point that comprises the extend property district.Unit #1 in Figure 53 A is in unit #4, and unit #1 comprises the starting point in extend property district, and unit #3 comprises the terminal point in extend property district.Here hypothesis comprise the unit #3 of terminal point such as arrow " my5 " indicated to be moved to position between unit #1 and the unit #2.In this case, because unit #3 is positioned at after the unit #1 of the starting point that comprises the extend property district, therefore mobile edit cell 27 update area marker character not.

Here hypothesis comprise the unit #3 of terminal point such as arrow " my5 " indicated to be moved to position before the unit #1.Figure 54 A and 54B have shown the process of update area marker character when moving the unit of the terminal point that comprises the extend property district.In this case, because unit #3 is positioned at before the unit #1 of the starting point that comprises the extend property district, so this moves the fault of the correctness aspect that causes the extend property district.For fear of this fault, shown in Figure 54 B, mobile edit cell 27 is the update area marker character in such a way, makes that the terminal point in extend property district is the terminal point of adjacent unit #2 after unit #1.

According to aforesaid present embodiment, even also can prevent fault aspect the correctness in extend property district when being moved freely by the user at a unit.

Though present embodiment has only been described the situation of the district's marker character that is arranged in the PGC information, nothing it should be noted that identical mobile processing can be carried out on the district's marker character in being arranged on vob information.

And though present embodiment has only been described moving of unit, nothing it should be noted that extend property district itself also can be moved except that the unit.
