Information recording medium recording information recording device, information recording method and recording control program {INFORMATION RECORDING APPARATUS, INFORMATION RECORDING METHOD AND INFORMATION RECORDING MEDIUM IN WHICH RECORDING CONTROLLING PROGRAM IS RECORDED}
[11] TECHNICAL FIELD The present invention relates to the technical field of an information recording apparatus, an information recording method, and an information recording medium on which a recording control program is recorded. More specifically, the information recording apparatus records information such as music information or image information on a recording medium; An information recording method and a technical field of an information recording medium having recorded thereon a recording control program for information recording.
[12] In recent years, the recording capacity has increased in the optical disc field. Accordingly, a reproduction-only optical disk (digital video display, DVD) in which a movie or the like is compressed and recorded has become popular.
[13] In this case, there are approximately two types of recording methods for recording information such as movies (usually called contents) on a large capacity optical disc.
[14] The first recording method is a recording method called an authoring method irrelevant to real time. The reproduction control information (also referred to as navigation information in the DVD standard) for controlling the reproduction type of the information to be recorded is formed in advance on the hard disk or the like with respect to all the above-mentioned information in consideration of the relationship between the information and the reproduction control information. One reproduction control information and corresponding information main body (content) are collected and recorded on an optical disc in a DAO (disc-at-once) manner.
[15] Further, as the second recording method, for example, an information main body that propagates through television broadcasting is received, the information main body is recorded on an optical disc in real time, and reproduction control information and the like related to the information main body are generated, There is a recording method for recording on an optical disc as a file different from the file.
[16] The reproduction-only DVD described above records the reproduction control information and the corresponding information main body generated based on the authoring method among the two methods described above regardless of the real time. In this case, instead of recording the information or the like directly on the above-described reproduction DVD, the reproduction control information and the information main body are recorded on the disc for mass production of the reproduction-only DVD in which the information is recorded, and then generated based on the disc. A copy process is performed using a stamper disk. Therefore, the above-mentioned reproduction-only DVD is manufactured in large quantities.
[17] On the other hand, recently, DVD-R (DVD-Recordable, DVD that can be recorded only once) and DVD-RW (DVD-Re-Recordable, DVD that can be recorded many times) are manufactured as recordable DVD. As for the DVD-RW, a video recording standard using the above-described second recording method is established, and an application standard is planned for the DVD-R.
[18] In addition to the above-mentioned DVDs, CDs (compact discs), CD-Rs (CD-Recordables), CD-RWs (CD-Rewritable, CDs) can be manufactured as optical discs popularized at present. It is common for one information reproducing apparatus to be formed to reproduce each of these optical discs in order to improve compatibility.
[19] However, when comparing playback-only DVDs to DVD-Rs and DVD-RWs, playback-only DVDs generate, collect, and record non-real-time playback control information and information bodies, whereas DVD-Rs and DVD-RWs do not. In real time, the reproduction control information and the information main body are generated and recorded as independent files. Therefore, a problem in that information recorded on DVD-Rs and DVD-RWs cannot be reproduced by using an information reproducing apparatus for reproducing information on a reproduction-only DVD, or playback-only DVDs for reproducing information recorded on DVD-Rs and DVD-RWs. There has been a problem that a large-scale change of the dragon information reproducing apparatus is required.
[20] SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and the problem to be solved by the present invention is that information can be reproduced by an information reproducing apparatus for a reproduction-only optical disc in which information is recorded in real time, when information is recorded in real time.

[53] Preferred embodiments of the present invention will be described with reference to the drawings.
[54] The embodiment described below is applied to an information apparatus for recording record information such as an image on a DVD-R as a recordable recording medium on a DVD video standard code. The DVD video standard is a recording format standard for information such as movies on a reproduction-only DVD (the corresponding standard name is "JIS X6241 120mm DVD reproduction-only disc standard").
[55] (I) Embodiment of the DVD Video Standard
[56] Before the embodiment is described in detail, the above-described DVD video standard supported as a recording format in the information recording apparatus of this embodiment will be briefly described with reference to Figs.
[57] 1 and 3 also illustrate the physical recording format in the DVD video standard. 2 illustrates a structure of a group of pictures (GOP) in the DVD video standard. 4 illustrates a logical format in the DVD video standard.
[58] As shown in Fig. 1, a DVD1 having recorded information according to the DVD video standard has a lead-in area LI at its maximum inner circumference and a lead-out area LO at its maximum outer circumference. Has Video information and audio information are divided into a plurality of video title sets (VTSs) 3 (VTS # 1 to VTS #n) having ID (identification) numbers between the maximum inner circumference and the maximum outer circumference and recorded respectively.
[59] In this case, the VTS means a set (integrated) batch-related titles having the same number of audio information and sub-picture information (i.e., information of a sub-picture such as a subtitle such as a movie), or the same attributes such as means and corresponding language. These titles are works that producers, such as movies, want to present to viewers. More specifically, for example, different titles are recorded for a plurality of movies that are the same as one movie and have subtitles in different languages or the like. In addition, even the same movie can record theatrical edition and the special edition in different titles.
[60] Also, the video manager 2 is recorded just before the area for recording the VTS3. The VMGI (Video Manager Information) recorded as the video manager 2 includes, for example, information related to all video information and audio information recorded on the DVD1. For example, a menu indicating the name of each title, information for preventing piracy or an access table for accessing each title, and backup information of such information are included.
[61] In addition, between the video manager 2 and the lead-in area LI, a file system showing the volume information 4 for identifying the entire information recorded on the DVD1, the video manager 2, and the data file structure in each VTS 3; Record the information (5).
[62] One VTS 3 is recorded with the control data 11 at the head and divided into a plurality of VOBs 10 each having an ID number. The portion consisting of a plurality of VOBs 10 is called a VOB set (VOBS). An entity portion is called a VOB set in order to distinguish the control data 11, which is another data constituting the VTS 3, and the plurality of VOBs 10 including the substance of video information and audio information.
[63] In the control data 11 recorded at the head of the VTS 3, PGCI (Program Chain Information, Program Chain) including various information about a program chain which is a logical segment in which a plurality of cells (cells will be described later) are combined. Information such as information) and backup information thereof are recorded as VTSI (Video Title Set Information). Alternatively, in addition to the control information, the respective VOB 10 records the actual part of the video information and audio information (video or audio itself other than the control information).
[64] In addition, one VOB 10 is composed of a plurality of cells 20 each having an ID number. One VOB 10 is composed of a plurality of sets of cells 20 so that one cell 20 is not divided into two VOBs 10.
[65] One cell 20 is composed of a plurality of VOB units (VOBU) 30 each having an ID number. The VOB unit 30 refers to unit information including each of image information, audio information, and sub-picture information.
[66] Therefore, one VOB unit 30 includes a navigation pack 41 for storing control information for controlling data included in the VOB unit 30, video data 42 as image information, audio data 43 as voice information, and the like. It consists of sub-picture data 44 as sub-picture information. Only video data is recorded as the video data 42 and only audio data is recorded as the audio data 43. Alternatively, only the graphic data such as characters or the graphic as the sub-picture are recorded as the sub-picture data 44. In addition, it is defined as a standard in which there are eight kinds of audio that can be recorded on DVD1 and 32 kinds of sub-pictures that can be recorded.
[67] Alternatively, the reproduction time corresponding to the one VOB unit 30 (the reproduction time corresponding to the data recorded between the one navigation pack 41 and the adjacent navigation pack 41) has a length in the range of 0.4 seconds to 1 second. Record to have. Therefore, the navigation pack 41 is necessarily detected once in the range of 0.4 to 1 second during reproduction.
[68] Also, in one VOB unit 30, the navigation pack 41 must exist at the head thereof. However, each video data 42, audio data 43 and sub-picture data 44 need not be located in the VOB unit 30. Alternatively, when located in the VOB unit 30, the number or order thereof can be set arbitrarily.
[69] Each segment of video data 42, audio data 43, and sub-picture data 44 shown in FIG. 1 is generally referred to as a pack P. FIG.
[70] That is, in one VOB unit 30, the video data 42, the audio data 43, and the sub-picture data 44 are divided into packs P and recorded. In addition, the pack P which recorded the video data 42 is called a video pack, the pack P which recorded the audio data 43 is an audio pack, and the pack P which recorded the sub picture data 44 is called a subpicture pack. . In addition, read start time information called an SCR (System Clock Reference) is recorded in a pack header recorded at the head of each pack (P). The SCR indicates the read start time on the reproduction time axis when data contained in each pack P is read from a track buffer in an information reproducing apparatus for reproducing information recorded on DVD1 and input to each buffer is started. Alternatively, for each pack P described above, video data 42, audio data 43 or sub-picture data 44 are normally recorded for each packet as a recording unit obtained by further subdividing the pack P. FIG. However, according to the DVD1 of the present embodiment, one pack P generally consists of one packet.
[71] As a result, the navigation pack 41 includes DSI data 51 including search information (e.g., an address on the DVD1 in which the video and audio to be reproduced and displayed) is searched for searching for video and audio to be played and displayed. And PCI data 50 including information on playback display control in the case of displaying the video or audio searched according to the DSI data 51. The DSI data 51 and the PCI data 50 are recorded by forming a DSI packet and a PCI packet as packets PT, respectively.
[72] In addition, all video data 42 included in one VOB unit 30 includes one or a plurality of group of pictures (GOPs).
[73] The DSI data 51 and the PCI data 50 will be described later in detail.
[74] Alternatively, the PCI data 50 includes highlight information that defines the display or operation when the viewer selects a specific selection item. According to the highlight information, for example, a change in the screen display related to item selection in an image (menu screen) indicating an item to be selected by the viewer, a display position to be changed according to the selection, and a command for the selected item (i.e., for the selected item). Command indicating the operation to be performed).
[75] Image information for displaying a frame, a selection button, and the like necessary for constructing and displaying a menu screen is recorded as the sub-picture data 44, which is the above-mentioned sub-picture information.
[76] The above-described GOP is a single minimum picture unit determined by the MPEG (Moving Picture Expert Group) 2 method, which is an image compression method employed when recording video information on DVD1 of the present invention. When the video data 42 included in the GOP is to be displayed at the head of each GOP, the reproduction display time information called PTS (Presentation Time Stamp) indicating the reproduction time on the reproduction time axis is recorded.
[77] Next, an overview of the MPEG2 system will be described. In general, frame images before and after one frame image in a continuous frame image are often similar to each other and have a mutual relationship. In the MPEG2 scheme, based on a plurality of frame images transmitted at several frame intervals, separate frame images existing among the plurality of frame images are generated by an interpolation operation based on a motion vector of the original image or the like. In this case, when recording a separate frame image, by recording only the information on the difference and the motion vector between the plurality of frame images, the separate frame image can be predicted with reference to the recorded information, and the separate frame image during reproduction Can play. Therefore, the image can be compressed and recorded.
[78] In addition, the outline of the above-described GOP will be described with reference to FIG. 2. 2 shows an example of a plurality of frame pictures for constructing one GOP. 2 shows a case where one GOP 52 is composed of 12 frame pictures. [The number of frame pictures included in one GOP 52 is not constant in the MPEG2 system.] In a frame picture, a frame picture indicated by reference numeral "I" called an I picture (Intra-coded picture) is used. The complete frame image can be reproduced with only its own image. Alternatively, a frame picture denoted by "P" called a P picture (Predictive-coded picture) is decoded by a difference from a predicted picture compensated and reproduced according to an already decoded I picture or another P picture. It is a generated predictive image. Alternatively, the frame picture indicated by the symbol "B", referred to as a B picture (Bidirectionally predictive-coded picture), is a future I picture or a future P recorded on an optical disc as well as an already decoded I picture or P picture. It is a predictive image reproduced for prediction using a picture. 2 shows the prediction relationship (interpolation relationship) between the pictures by an arrow.
[79] In addition, the general MPEG 2 scheme used in the DVD1 according to the present invention adopts a variable ratio scheme in which the amount of data included in each GOP 52 is not constant. That is, since each picture included in one GOP 52 corresponds to a fast moving video, when the correlation between each picture is small, the amount of data for constructing each picture increases. Therefore, the amount of data contained in one GOP 52 also increases. On the other hand, since each picture included in one GOP 52 corresponds to a moving picture with little movement, when the correlation between each picture is large, the amount of data for constructing each picture is also reduced, so that one GOP 52 The amount of data included in the) also decreases.
[80] In the recording format having the hierarchical structure described above with reference to Fig. 1, each segment is manufactured and set freely according to the intention of the producer to record. Reproduction in various segments can be achieved by reproducing according to the logical structure described later for each segment.
[81] A physical data structure of the above-described DSI data 51 and PCI data 50 will be described with reference to FIG. 3.
[82] First, as shown in FIG. 3, the PCI data 50 is composed of general information 55 as the main body of the PCI data 50 and other information 56 as the remaining information.
[83] In addition, the general information 55 includes the navigation pack relative position information 70 which is the relative recording address information at the head of the VOB 10 of the navigation pack 41 described above, and the VOB unit 30 including the navigation pack 41. VOBU playback start time information 71 indicating the playback start time on the playback time axis of the VOBU, VOBU playback end time information 72 indicating the playback end time on the playback time axis of the VOB unit 30, and other information 73 as the remaining information. Is done.
[84] The DSI data 51 includes general information 75 serving as the main body of the DSI data 51, VOB information 76 which is information about the VOB 10 to which the navigation pack 41 belongs, and the VOB unit to which the navigation pack 41 belongs. VOBU search information 77 indicating the recording position on the DVD1 of another VOB unit 30 reproduced before and after 30, and other information 78 which is the remaining information.
[85] The general information 75 includes navigation pack relative position information 85 similar to the navigation pack relative position information 70 described above, and a VOBU identification number 86 for identifying the VOB unit 30 to which the navigation pack 41 belongs. ) And other information 87 which is the remaining information.
[86] Further, the VOB information 76 includes the VOB playback start time information 80 and the VOB 10 indicating the playback start time on the playback time axis of the VOB 10 to which the VOB unit 30 including the navigation pack 41 belongs. The VOB playback end time information 81 representing the playback end time on the playback time axis and other information 82 which is the remaining information.
[87] As the VOBU search information 77, as shown in FIG. 3, the recording position on the DVD1 of the next VOB unit 30 and the one preceding VOB unit 30 of the VOB unit 30 to which the navigation pack 41 belongs is set. The positional information is included as a list indicating the positional information indicating and the positional information indicating the recording position on the DVD1 of another VOB unit 30 to be reproduced in the range of 120 seconds to 120 seconds before the start time of the VOB unit 30.
[88] The logical format (logical structure) obtained by combining the information recorded in the physical segments shown in FIG. 1 or 3 will be described with reference to FIG. Alternatively, instead of actually recording the information on the DVD1 in the logical structure shown in FIG. 4, the information (access information) for combining and reproducing each data (particularly the cell 20) shown in FIG. 1 with the logical structure shown in FIG. Or time information, etc.) are recorded on the DVD1, particularly in the control data 11.
[89] For clarity, the lower layer of FIG. 4 will be described. By selecting and combining a plurality of cells 20 in the above-described physical structure in FIG. 1, one program 60 is logically constructed according to the intention of the producer. This program 60 is also the smallest logical unit that can be accessed by the system controller of the information reproducing apparatus described above by identifying segments and using commands. Alternatively, since the viewer can freely select and view one cell 20 or a plurality of cells 20, the producer can define the program 60 as the minimum unit. This unit is called PTT (Part of Title).
[90] In addition, since one program 60 is logically performed by selecting a plurality of cells 20, one cell 20 may be used as the plurality of programs 60. That is, a so-called producer who reproduces one cell 20 in a plurality of different programs 60 may use the cell 20 excessively.
[91] The number of one cell 20 is treated as a cell ID number when the cell 20 is handled in the physical format shown in FIG. On the other hand, when the cell 20 is handled in the physical format shown in Fig. 4, the number of cells 20 is treated as a cell number in the description order in PGCI described later.
[92] By combining a plurality of programs 60, one PGC (Program Chain) 61 is logically made according to the intention of the producer. The above-described PGCI is defined in units of the PGC 61. In the PGCI, when reproducing each program 60, the regeneration order of the cells 20 for each program 60 (a specific program number is assigned to each program 60 according to the regeneration order). The address which is the recording position on the DVD1 of the cell 20, the number of the head cell 20 to be reproduced by one program 60, the reproduction method of each program 60, and various commands (each PGC 61 or each cell 20). Command) which can be indicated according to the manufacture of each). In the case of recording information on DVD1 according to the present embodiment, a manufacturer can play one of the normal playback, random playback, and shuffle playback for each PGC 60 in order to reproduce the program 60 during playback. Select. Since random reproduction is performed using random numbers, the same program 60 can be reproduced many times. The shuffle play is a random play using a random number similar to the above-described random play. However, since the program 60 is played only once, the same program 60 is not played back many times.
[93] The recording position of the PGCI on the DVD1 is in the above-described control data 11 (see Fig. 1). However, when the PGCI is related to a menu in the video manager 2, the recording position of the PGCI is located in the control data (not shown) included in the video manager 2.
[94] In addition, one PGC 61 may include data such as a real image and an audio in a combination of the program 60 (that is, a combination of the cells 20) in addition to the above-described PGCI.
[95] In addition, in one PGC 61, the cell 20 as described above in the description of the program 60 may be redundantly used. (I.e., the same cell 20 is used as another PGC 61.) Alternatively, a method of reproducing the cell 20 in the order stored in the DVD1 with respect to the cell 20 to be used. In addition to the method, the producer may reproduce the cell 20 irrespective of the order in which the cells 20 are stored on the DVD1 (for example, to play the cell 20 recorded later first) (discontinuously arranged). Cell playback method) can be selected.
[96] One title 62 is logically composed of one or more PGCs 61. For example, this title 62 is a unit corresponding to a movie, and is information that a producer wants to provide to the viewer of DVD1.
[97] One VTS 63 is logically composed of one or more titles 62. The titles 62 included in the VTS 63 each have a common attribute. For example, with respect to one and the same movie, the movie has a different language corresponding to each title 62. Alternatively, the information corresponding to one VTS 63 shown in FIG. 4 corresponds to the information included in one VTS 3 shown in FIG. That is, all information logically contained in the VTS 63 shown in FIG. 4 is recorded on the DVD1 as one VTS3.
[98] In accordance with the logical format described above, the producer defines information segmented in the physical structure, thereby forming a title (movie, etc.) that the viewer can watch.

[102] The DVD-R according to the present embodiment includes an optical disc capable of recording only once, using the dye film as the recording film. In the plan view, the DVD-R has a center hole CH at its center for fixing the DVD-R to a spindle motor for rotating the DVD-R in the information reproducing apparatus or the information recording apparatus. The DVD-R further has a non-recording area 110 in which recording information therefrom cannot be recorded in the inner periphery, a recordable area PA in which the recording information can be recorded, and an end area EA in which the recording information cannot be recorded in the outer periphery. .
[103] In addition, the recordable area PA includes a beam intensity test area 111 for recording test information for setting the light beam intensity used for recording the record information, data of the set light beam intensity, and management data described later in the recording process. A file system which is information indicating a file structure of the management data area 112 to be recorded, the lead-in area LIA in which recording start information and the like, which are read out at the start of reproduction of the recorded information, are recorded during the recording process of the recording information. File system information area (FS) in which the information is recorded, data area (DA) in which the actual recording information is recorded, and lead-out area (LOA) in which the end information for reading out the recorded data at the end of reproduction is recorded in the recording process. Is done.
[104] The management data area 112 also includes an identification information area 115 in which identification information for identifying the DVD-R 1R itself with other DVD-Rs is updated, and management data necessary for the recording process described later can be updated. It comprises a first management data area (116 _{- 1)} to n-th managing data area (116 _-n) for recording each time. The maximum value of n described above is "699".
[105] In addition, one management data area 116 is composed of a link area LA in which information on connection with an adjacent management data area is recorded, and 14 management data small areas MD. Here, the fourteen management data small areas MD refer to the first management data small areas MD1 to 14th management data small areas MD14, each of which records information constituting a part of the management data area 116, which will be described later.
[106] (III) An embodiment of the information recording and reproducing apparatus
[107] According to this embodiment, recording information based on the above-described DVD video standard is recorded on a DVD-R (1R) or a DVD-RW in real time, and at the same time, the recorded information is reproduced from a DVD-R (1R) or a DVD-RW. An information recording / reproducing apparatus for the above is described with reference to FIGS.
[108] 6 is a block diagram showing the outline structure of the information recording / reproducing apparatus according to the present embodiment. 7 is a flowchart showing information recording processing according to the present embodiment. 8 is a diagram showing a change of the DVD-R 1R during the information recording process according to the present embodiment. 9 is a diagram showing a change of the above-described management data recorded in the information recording process of the embodiment.
[109] As shown in Fig. 6, the information recording / reproducing apparatus S according to the present embodiment includes a pickup 120 as a first recording means, a second recording means and a third recording means, a modulator 121, a formatter. (formatter) 122, video encoder 123 which is an encoding device, audio encoder 124, system controller 125 as securing means and second securing means, unit information forming apparatus, higher unit information forming apparatus, format information generation Device, Memory 127, Demodulator 128, Video Decoder 129, Audio Decoder 130, Servo Integrated Circuit (IC) 131, Spindle Motor 132, Manipulator 133 ), A multiplexer 134, and a demultiplexer 135. The system controller 125 also includes a navigation information generator 126 as an address information generating device for generating the above-mentioned navigation pack 41 and the like.
[110] Next, the outline operation of each part is demonstrated.
[111] First, the spindle motor 132 rotates the loaded DVD-R 1R at a preset rotation speed in accordance with the spindle control signal Sss from the servo IC 131.
[112] On the other hand, the video information Sv as the recording information to be recorded in the data area DA of the DVD-R 1R is externally input and then input to the video encoder 123.
[113] The video encoder 123 performs an encoding process at a fixed code rate preset for the video information Sv based on the control signal Scv from the system controller 125, and generates an encoded video signal Sev. Output to the multiplexer 134. Specifically, for example, the encoding process is a compression encoding process of the MPEG2 system described above, and uses a coding rate at which the playback time of one VOB unit 30 is 0.5 seconds. 0.5 second corresponds to the playback time of 15 video frames in the NTSC (National Television System Committee) method.
[114] On the other hand, audio information Sa, which is recording information to be recorded in the data area DA of the DVD-R 1R, is input from the outside and then input to the audio encoder 124.
[115] The audio encoder 124 performs an encoding process at a fixed coding rate preset on the audio information Sa based on the control signal Sca from the system controller 125, and generates an encoded audio signal Sea. To the multiplexer 134. Specifically, for example, the encoding process is the above-described compression encoding process of the MPEG2 system, and the coding rate is used such that the reproduction time of one VOB unit 30 is 0.5 seconds as in the case of the video information Sv.
[116] Therefore, the multiplexer 134 superimposes (or multiplexes) the image information and the audio information included in the encoded video signal Sev by a predetermined process, and generates an overlapping signal Smx and outputs it to the formatter 122.
[117] The multiplexer 134 passes the above-described encoded audio signal Sea as it is to form an overlapping signal Smx.
[118] The formatter 122 selects the navigation information signal Snd from the navigation information generator 126 described later and the above-described superimposition signal Smx based on the control signal Scf from the system controller 125 in FIG. 1 or 3. After combining so as to be in the format of the physical format shown in Fig. 2, a format signal Smt is generated and output to the modulator 121.
[119] Each recording information input to the formatter 122 as the superimposition signal Smx is transmitted to the system controller 125 as the recording information signal Sfm at a preset timing for use in the generation of the navigation information described above by the navigation information generator 126. Output
[120] The modulator 121 performs a preset modulation process (specifically, for example, 8-16 modulation process) on the format signal Smt, generates a modulated signal Sfe, and outputs the modulated signal Sfe to the pickup 120. do.
[121] Therefore, the pickup 120 generates the light beam B whose intensity is modulated by the modulation signal Sfe, and irradiates the light beam B on the information track in the information recording surface (not shown) of the DVD-R 1R. The above-described navigation information included in the modulated signal Sfe and the feet corresponding to the respective recording information are formed on the information track. Next, the navigation information and each record information are recorded on the DVD-R 1R in the format of the physical format shown in Figs.
[122] The deviation of the direction perpendicular to the information recording surface and the horizontal direction between the condensing position of the light beam B and the above-described information track is not shown in the pickup 120 in accordance with the pickup servo signal Ssp output from the servo IC 131. This is solved by moving the objective lens (the objective lens for condensing the light beam B) in the vertical direction and the horizontal direction, that is, focus servo control and tracking the servo control.
[123] Accordingly, the servo IC 131 generates the above-described spindle control signal Sss and the pickup servo signal Ssp in accordance with the control signal Ssc from the system controller 125, so that they are respectively obtained by the spindle motor 132 and the pickup ( 120).
[124] On the other hand, when reproducing the recording information or the like already recorded on the DVD-R 1R, the pickup 120 generates a light beam B for reproduction having a predetermined intensity and irradiates the information track having the above-described pits, Accordingly, a detection signal Spp corresponding to the recording information or the like is generated and output to the demodulation unit 128.
[125] Therefore, the demodulation unit 128 performs demodulation processing corresponding to the modulation processing in the above-described modulation unit 121 with respect to the detection signal Spp, and generates a demodulation signal Spd and outputs it to the demultiplexer 135.
[126] When the demodulation signal Spd includes video information, the demultiplexer 135 separates image information and audio information included in the video information, generates a separation signal Sdmx, and outputs the separated signal Sdmx to the video decoder 129.
[127] On the other hand, when the demodulation signal Spd includes audio information, the demultiplexer 135 passes the demodulation signal Spd as it is and outputs it to the audio decoder 130.
[128] The video decoder 126 performs decoding processing corresponding to the encoding process of the fixed code rate in the video encoder 123 described above with respect to the separated signal Sdmx based on the control signal Scdv from the system controller 125. Then, the decoded video signal Sdv is generated and outputted to an external monitor or the like.
[129] In addition, the audio decoder 130 performs encoding processing of the fixed code rate on the audio encoder 124 with respect to the demodulated signal Spd including the audio information based on the control signal Scda from the system controller 125. Corresponding decoding processing is performed to generate a decoded audio signal Sda, which is then output to an external amplifier or the like.
[130] On the other hand, when the user executes an operation for executing the recording process or the reproduction process in the information recording / reproducing apparatus S, the operation unit 133 generates an operation signal Sin corresponding to the operation to generate a system controller. Output to 125.
[131] In addition, the navigation information generator 126 performs each of the above-described navigations to be recorded on the DVD-R 1R during recording processing described later under the control of the system controller 125 based on the operation signal Sin and the recording information signal Sfm. The previous navigation information signal Snd including the information is generated and output to one of the input terminals of the formatter 122.
[132] Therefore, the formatter 122 described above superimposes the recording information in the superimposition signal Smx and the navigation information in the navigation information signal Snd, and includes a format signal Smt including recording information having the physical format shown in FIGS. 1 and 3. )
[133] In parallel with this operation, the system controller 125 exchanges information required by the memory signal Sm with the memory 127, and controls each control signal Scv, Sca, Scf, Ssc, Scdv, Scda for controlling each operation. ) Is generated and output to the corresponding constituent members.
[134] 6 to 9, an information recording process according to the present embodiment which mainly executes the system controller 125 in the information recording / reproducing apparatus S will be described.
[135] In the following description, as shown in Fig. 8A, the case where recording information is recorded on the DVD-R 1R in real time so that the recording format becomes the same as the reproduction-only DVD1 in which the two VTSs 3 are recorded will be described. .
[136] According to the information recording process of this embodiment, as shown in Fig. 7, the type of the optical disc initially loaded into the information recording / reproducing apparatus S is determined according to a known method. (Step S1)
[137] If the optical disc of the above-identified type is a DVD-RW capable of being rewritable many times (step S1, RW), the recording process is executed on the DVD-RW based on the above-described video recording standard (step S20), and the process ends.
[138] On the other hand, when the optical disc loaded in the determination of the step S1 is a DVD-R (1R) (step S1, R), as shown in the first diagram from the left in Fig. 8B, it corresponds to the DVD video standard on the DVD-R (1R). A reservation of the first recording area 98 is secured as an area. (Step S2) The first recording area 98 includes the volume information 4 of the DVD video standard, the file system information 5, the above-described VMG 12A constituting the video manager 2, and the VOBS 2B for menus. This is an area for recording information corresponding to (VOBS as a set of image information or audio information for displaying a necessary menu) and backup VMGI 2C.
[139] When the reservation of the first recording area 98 is secured, the reservation of the second recording area 99 corresponds to the DVD video standard on the DVD-R 1R as shown on the left side of FIG. Secured in the area. (Step S3) The second recording area 99 is an area for recording information corresponding to the first VTSI 90A, and the first VTSI 90A is a VTSI corresponding to the first VTS 3 in the DVD video standard. .
[140] As a result, the remaining recordable area PA after the second recording area 99 becomes the undetermined third recording area 99.
[141] Once the reservation of the first recording area 98 and the second recording area 99 is completely secured, a parameter indicating the number of the VOB 10 to be recorded as the first VTS 3 on the system controller 125 is then obtained. Initialize (Step S4) The relative position information of the navigation pack to be included in the VOB 10 is also initialized on the system controller 125. (S5 step)
[142] When the end of each initialization, and records the following data to the management area the first management data (M1) shown in Fig. 9 in the fourth managing data small area (MD4) in the first management data area _(116-1) in 112 . Therefore, the reserved first recording area 98 and second recording area 99 are recorded. (Step S6) In the first management data M1, "0h (h represents hexadecimal notation.)", Which is the first address of the first recording area 98, and ", which is the first address of the second recording area 99, are referred to. 600h "and" 630h "which are the head addresses of the undetermined third recording area 99 are respectively recorded in the corresponding area. At this time, since the final recording positions of the first recording region 98, the second recording region 99, and the undetermined third recording region 99 are undetermined, all areas corresponding to the final recording position are zero data ( zero data).
[143] When recording of the first management data M1 is completed, the process of step S6 and the first navigation pack 41 as the first VTS 3 are additionally generated in the navigation information generator 126 to generate an undetermined third. It records in the recording area 99. Since the encoding process of the present invention is performed at a fixed coding rate so that the playback time of one VOB unit 30 is always 0.5 seconds, the recording position of each VOB unit 30 is also fixed as a result. Therefore, the navigation pack 41 can be generated and recorded before recording the actual portion of the record information.
[144] When recording of the first navigation pack 41 is finished, the actual recording information is then encoded at the fixed coding rate as described above, and the information encoded following the first navigation pack 41 is recorded in the undetermined third recording area 99. do. (Step S7).
[145] Then, it is checked whether or not the encoding process and the recording process of recording information corresponding to one VOB unit 30 have been completed. (Step S8) If not complete (step S8, NO), the coding process and the recording process are continued. On the other hand, when the encoding process and the recording process of the recording information corresponding to one VOB unit 30 are completed (step S8, YES), a value corresponding to the data amount of one VOB unit 30 until then is obtained. After adding to the value of the navigation pack relative position information, the navigation pack relative position information value is changed on the system controller 125 to the following navigation pack relative position information value (step S9), and 60 VOB units 30 are added. Check whether the recording has finished. (S10 step)
[146] If the recording of the 60 VOB units 30 has not been completed (step S10, NO), the process returns to step S6 to record the next VOB unit 30. On the other hand, when recording is completed (step S10, Yes), the identification number of the VOB 10 is updated. (S11 step)
[147] When the above processing is completed, the VOB 10 including 60 VOB units 30 having a reproduction time of all 0.5 seconds, that is, the reproduction time of 30 seconds is formed in the undetermined third recording area 99.
[148] After the step S11 is finished, it is checked whether or not an operation indicating to stop the recording process for the DVD-R 1R is executed during the above-described recording process (step S12). (Step S12) If the above operation is not performed (step S12, NO), the process returns to step S5 described above and the process is executed in steps S5 to S11 described above.
[149] On the other hand, when an operation indicating to stop the recording process for the DVD-R 1R is executed (step S12, Yes), next, the undetermined third recording area 100 and the second recording area 99 are determined. Run the process. (Step S13, S14)
[150] In this step S13, the second backup first VTSI 90C is recorded from the left in FIG. 8B following the step S11. Record the following, the management data area, the second management data (M2) as shown in Figure 9 in a fourth managing data small area (MD4) in the second management data area _(116-2) in 112. In addition, the above-mentioned first management data M1 is invalidated. Therefore, the recording of the completion of the first recording process (first recording process of the VTS 3) to the unconfirmed third recording area 100 is recorded. More specifically, in the second management data M2, "0h", which is the first address of the first recording area 98, "600h", which is the first address of the second recording area 99, and an undetermined third recording area ( &Quot; 630h ", which is the head address of 100, is respectively recorded in the corresponding area. At the same time, "659 + slh"("sl" is the size of the address area occupied by the first VOBS 90B), which is the final address of the backup first VTSI 90C, and the head of the undetermined fourth recording area 100A. Each address "660 + s1h" is recorded in the corresponding area. At the end of step S13, the final recording positions of the first recording region 98, the second recording region 99, and the new undetermined fourth recording region 100A are undetermined and thus correspond to this final recording position. All areas are zero data.
[151] In step S13, the process returns to the second recording area 99 to record the original first VTSI 90A (which has the same contents as the backup first VTSI 90C described above). Record the Thereafter, the management data area, the third management data (M3) shown in Figure 9 in a fourth managing data small area (MD4) in the third managing data area _(116-3) in 112. In addition, the second management data M2 described above is invalidated. Therefore, the completion of the recording process (recording process of the first VTSI 90A) for the second recording area 99 is recorded. More specifically, in the third management data M3, " 0h " of the first address of the first recording area 98, " 600h " of the first address of the second recording area 99, undetermined third recording area 100 The head address " 630h " At the same time, "659 + s1h" which is the final address of the backup first VTSI 90C, "660 + s1h" which is the first address of the undetermined fourth recording area 100A, and the final address of the second recording area 99 are used. &Quot; 629h " (finishes the recording processing of the first VTSI 90A) is recorded in the corresponding areas, respectively. At the end of step S14, the final recording positions of the first recording area 98 and the fourth recording area 100A are undetermined, and therefore all areas corresponding thereto are referred to as zero data.
[152] After finishing the processing in step S14, it is checked whether or not new recording processing for the DVD-R 1R should be started. (Step S15) According to the present embodiment, the second VTS 3 is also recorded (step S15, yes), so that the number of the VTS is updated to "2" at the next position (step S17), and the previous step S3 is performed. The processing is returned to execute the processing of steps S3 to S14 for the second VTS 3 described above.
[153] In the series of processes for the second VTS 3, first, as shown third from the left in FIG. 8B, it corresponds to the second VTSI 91A which is the VTSI corresponding to the second VTS 3 in the DVD video standard. An area (recording area) for recording information to be recorded is reserved in an area corresponding to the DVD video standard on the undetermined fourth recording area 100A. The reserved area is defined as a new fourth recording area 101. (Step S3) For the sake of simplicity, the reservation securing process of the fourth recording area 101 is shown as "second recording area reservation" in FIG.
[154] As a result, the remaining recordable area PA after the new fourth recording area 101 is defined as the undetermined fifth recording area 100B.
[155] After the reservation of the fourth recording area 101 is secured, steps S4 to S13 are executed to execute the second VOBS 91B and the backup agent in the undetermined fifth recording area 100B and the fourth recording area 101. The 2 VTSI 91C and the second VTSI 91A are recorded in this order.
[156] ₉ in the fourth management data small area MD4 in the fourth management data area 116-4 in the management data area 112 before recording the navigation pack 41 in the undetermined fifth recording area 100B. The fourth management data M4 shown is recorded. In addition, the third management data M3 described above is invalidated. Therefore, the reservation made by the fourth recording area 101 is recorded. In the fourth management data M4, "0h" which is the head address of the first recording area 98, "600h" which is the head address of the original second recording area 99 (first VOBS 90A), and original. "630h" which is the head address of the third recording area 100 (the first VOBS 90B and the backup first VTSI 90C), and "659 + s1h" which is the last address of the backup first VTSI 90C. "660 + s1h" which is the head address of the fourth recording area 101 and "690 + s1h" which is the head address of the new undetermined fifth recording area 100B are respectively recorded in the corresponding area. When the step S5 ends twice, the final recording positions of the first recording area 98, the fourth recording area 101, and the new undetermined fifth recording area 100B are undetermined, and thus corresponding All areas are called zero data.
[157] Further, in claim 2 VTSI fourth managing data small area (MD4) in the fifth managing data area _(116-5) in the after end of recording (91A), the management data area 112 for indicating a recording position information of each recording area Fifth management data (not shown) is recorded.
[158] At this time, the second VOBS 91B, the backup second VTSI 91C, and the second VTSI 91A are recorded in the corresponding areas as shown in the second to the right of FIG. 8B.
[159] If the above-described determination of step S15 is made again and a new recording process is not started (step S15, NO), it is then checked whether or not the end process (so-called final process) should be executed again. (Step S16) If it is determined that the termination process should not be executed (step S16, NO), the process returns to step S15. On the other hand, when it is determined that the termination process should be executed (step S16, Yes), next, in the above-described first recording area 98 in which the reservation is secured in step S2, the volume information 4 of the DVD1 (DVD video standard), Information corresponding to the file system information 5, the above-described VMCI 2A constituting the video manager 2, the VOBS 2B for menus, and the backup VMGI 2C is recorded. Record the Thereafter, the management data area, the sixth managing data area, the fourth area, the sixth managing data source management data (not shown) that indicates the position of each recording area in the (MD4) in the _(116-6) in 112 The first recording area 98 is closed. (Step S18) The previous start information to be recorded in the lead-in area LIA and the previous end information to be recorded in the lead-out area LOA are recorded (step S19) to complete all the recording processes.
[160] After completing the processing up to step S18, as shown in the first diagram on the right in FIG. 8B, recording processing of recording information according to real time in the DVD-R (1R) is performed in a recording format conforming to the DVD video standard. To complete. Therefore, the recording information recorded on the DVD-R 1R can be reproduced by using an information reproducing apparatus for reproducing the recording information on the reproduction-only DVD according to the DVD video standard. If the recording of the volume information 4 and the file system information 5 in the first recording area 98 is not completed, the information cannot be reproduced by the above-described information reproducing apparatus.
[161] As described above, when the information recording process is performed with the information recording / reproducing apparatus S of the present embodiment, the second recording area 99 and the fourth recording area 101 are reserved in advance, and then the record information and the respective VTSIs are reserved. The recording information and each VTSI can be recorded on the DVD-R (1R) while reliably complying with the DVD-Video standard.
[162] Moreover, since each recording area can be reserved and secured while recording the management data M and referencing this, each recording area can be reserved and secured accurately and reliably.
[163] In addition, since the recording information is composed of a plurality of VTSs, the VTSI corresponding to each VTS can be recorded while reliably complying with the DVD video standard.
[164] Furthermore, after recording all the recording information and all the VTSI on the DVD-R (1R), the VMGI 2A is recorded in the first recording area 98. Therefore, the VMGI 2A which accurately reduces the entire recording information is accurately generated and recorded. can do.
[165] Moreover, since each backup VTSI is recorded together with each original VTSI, even if any failure occurs in the detection of the original backup VTSI at the time of reproducing the record information, the backup VTSI can be reliably detected and the information can be continued.
[166] In the above-described embodiment, the case where DVD-R (1R), which is a DVD that can be recorded only once, is used as a recordable recording medium will be described. However, in addition to the above, the record information can be recorded in the above-described order as a recordable recording medium using the above DVD-RW, which is a DVD that can be recorded many times.
[167] In addition, a program corresponding to the flowchart shown in FIG. 7 is recorded on a flexible disk or a hard disk as an information recording medium, and read by using a personal computer (PC). It can be operated as (125).
[168] As described above, since the information and the reproduction control information are recorded after the reservation control information area is reserved in advance, the information and the reproduction control information on the recordable recording medium while reliably complying with the recording format for the reproduction-only recording medium. Can be recorded.
[169] Therefore, information can be recorded with respect to the recordable recording medium so that the information reproducing apparatus using the reproduction-only recording medium that is currently generalized can be reproduced.
[170] In addition, since the reservation control information area can be secured while recording the management information and referring to the management information, the reservation control information area can be secured accurately and securely.
[171] Further, since the information is composed of a large number of unit information and the reproduction control information is unit control information recorded for each unit information, unit control information corresponding to each unit information can be recorded while reliably complying with a recording format for a reproduction-only recording medium. Can be.
[172] Then, after all the information and all the unit control information have been recorded on the recordable recording medium, the entire control information is recorded in the entire control information area, whereby the entire control information for reducing the overall information can be accurately generated and recorded.
[173] In addition, since the backup reproduction control information is recorded together with the original reproduction control information, when the recorded information is reproduced, even if any failure occurs in the detection of the original reproduction control information, the backup reproduction control information is reliably detected. The reproduction of the information can be continued.
