2. Description of the Related Art At present, a system for reproducing an optical disc on which video (moving image), audio, etc. are recorded has been developed, and movie software and karaoke are available like an optical disc such as an LD (laser disc) or a video CD (video compact disc). It is widely used for the purpose of reproducing the information such as. On the surface of these optical discs, information indicating recorded contents such as a title is usually printed. Further, information indicating recorded contents such as a title is usually attached to the package of these optical disks. As a result, it is possible to know the recorded contents of the optical disc without reproducing the optical disc.

In recent years, internationally standardized MPEG
The DVD (Digital Versatile Disc) standard using the 2 (moving picture expert group) system and adopting AC-3 (digital audio compression) and other audio compression systems has been proposed. This DVD standard includes a playback-only DVD video (or DV
D-ROM), write-once DVD-R, and rewritable DVD-RW (or DVD-RAM).

According to the MPEG2 system layer, the standard of DVD video (DVD-ROM) is MPEG2 as a moving picture compression system and linear PC as an audio recording system.
In addition to M, it supports AC3 audio and MPEG audio. Furthermore, this DVD video standard
The sub-picture data is run-length-compressed bitmap data for subtitles, and control data (navigation data) for reproduction control such as fast-forward / rewind data search is added. In addition, this standard requires ISO96 so that data can be read by a computer.
It also supports 60 and UDF bridge formats.

An optical disk (DVD-ROM disk) used for a DVD video (DVD-ROM) is currently a 12-cm disk with one layer on one side and is about 4.7.
It has a storage capacity of GB (gigabyte). The two layers on one side have a storage capacity of about 9.5 GB, and the two layers on both sides are capable of recording a large capacity of about 18 GB (when a laser with a wavelength of 650 nm is used for reading).

On the other hand, an optical disk (DVD-RAM disk) used for DVD-RW (DVD-RAM) is
Currently, a 12 cm disc is approximately 2.6 on one side.
It has a storage capacity of GB (gigabyte), and has a capacity of 5.2 GB on both sides. DVD currently in practical use
-RAM disk is a DVD-ROM of the corresponding size
It has a smaller storage capacity than a disk. However, DVD
-Technical developments for expanding the capacity of RAM disks are constantly being made, and in the near future, DVD-RAM disks having a storage capacity of 4.7 GB or more on one side will definitely be put to practical use.

However, since the MPEG2 video file that can obtain high image quality has a large data size, the current D
With a VD-RAM disc (single-sided 2.6 GB disc or double-sided 5.2 GB disc), the recordable time is not sufficient (about 2.6 hours for a 2.6 GB disc, 5.2
About 2 hours with a GB disc).

Since the user can freely record data on the DVD-RAM disc, the information indicating the recorded contents is not normally printed on the surface of the disc. For the same reason, the package of the DVD-RAM disc usually does not have the information indicating the recorded contents printed thereon.

In order to be able to know the recorded contents of a DVD-RAM disc by just looking at the appearance, the following measures are required, for example. First, the user grasps the recorded contents recorded on the DVD-RAM disc. In addition, the user
Information indicating the recorded contents of the D-RAM disk is created.
Then, the user writes information indicating the recorded contents of the DVD-RAM disc on the surface of the disc. Alternatively, the user attaches information indicating the recorded contents of the DVD-RAM disc to the disc package.

[0010]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since the D-RAM disc does not have information about the recorded contents printed, there is a problem that the recorded contents of the optical disc cannot be known only by looking at the appearance of the disc.

Further, in order to be able to know the recorded contents of the optical disk by just looking at the outer appearance of the DVD-RAM disk, the user had to take a predetermined action on the disk.

An object of the present invention is to record an information recording medium (DVD
It is possible to easily control a device for reproducing an information recording medium useful for selectively displaying an arbitrary image with respect to the recorded contents of the information recording medium, without requiring reproduction of a RAM disk) and troublesome work. Another object of the present invention is to provide a remote control device for an information reproducing device.

[0013]

In order to solve the above-mentioned problems and to achieve the object, a first data recording area for storing a video object including image data forming a plurality of chapters, and the video object are provided. A recordable and reproducible second data recording area for storing control information necessary for managing and reproducing the image data, and a part of the second data recording area further includes the plurality of Information that enables recording and reproduction of a plurality of data indicating the storage locations of the plurality of image data so that the plurality of image data at any location of any chapter can be reproduced while skipping from the image data of the chapter A remote control device for transmitting a remote control signal to a reproducing device for reproducing a recording medium, wherein the operation unit includes the control unit. Using the first operation unit for instructing that the video data is reproduced using information, and the data indicating the storage location of the plurality of image data, the video data is reproduced while executing the skip. And a second operation unit for instructing to be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A digital information recording / reproducing system (information recording medium processing device) according to an embodiment of the present invention will be described below with reference to the drawings.

As a typical embodiment of the digital information recording / reproducing system according to the present invention, there is an apparatus for recording / reproducing a moving image encoded based on MPEG2 at a variable bit rate, for example, a DVD digital video recorder. (A specific example of this DVD digital video recorder will be described later.) FIG. 1 is a perspective view illustrating the structure of a recordable optical disc 10 used in the DVD digital video recorder.

As shown in FIG. 1, this optical disk 10
Is a pair of transparent substrates 1 each provided with a recording layer 17.
4 has a structure in which the adhesive layers 20 are bonded together. Each board 14
Can be made of polycarbonate having a thickness of 0.6 mm, and the adhesive layer 20 can be made of an ultrathin (for example, 40 μm thick) ultraviolet curable resin. These pair of 0.
By laminating the 6 mm substrate 14 so that the recording layer 17 is in contact with the surface of the adhesive layer 20, the large-capacity optical disk 10 having a thickness of 1.2 mm is obtained.

A center hole 22 is provided in the optical disk 10, and a clamp area 24 for clamping the optical disk 10 during rotational driving is provided around the center hole 22 on both sides of the disk. A spindle of a disc motor is inserted into the center hole 22 when the optical disc 10 is loaded in a disc drive device (not shown).
Then, the optical disc 10 is clamped in the clamp area 24 by a disc clamper (not shown) while the disc is rotating.

The optical disk 10 has, around the clamp area 24, an information area 25 in which video data, audio data and other information can be recorded.

A lead-out area 26 is provided on the outer peripheral side of the information area 25. In addition, the lead-in area 27 is provided on the inner peripheral side in contact with the clamp area 24.
Is provided. A data recording area 28 is defined between the lead-out area 26 and the lead-in area 27.

Recording layer (light reflecting layer) 17 in the information area 25
Recording tracks are continuously formed in, for example, a spiral shape. The continuous track is divided into a plurality of physical sectors, and these sectors are numbered consecutively. Various data is recorded on the optical disc 10 using this sector as a recording unit.

The data recording area 28 is an actual data recording area. As recording / reproducing information, video data (main image data) of movies, sub-image data of subtitles / menus, lines / sound effects, etc. are recorded. Audio data is recorded as a series of similar pits (a physical shape or phase state that causes an optical change in laser reflected light).

The optical disk 10 has a single-sided single layer and double-sided recording R
In the case of an AM disc, each recording layer 17 can be composed of a triple layer in which a phase change recording material layer (for example, Ge2Sb2Te5) is sandwiched between two zinc sulfide / silicon oxide mixtures (ZnS / SiO2).

The optical disk 10 has a single-sided single-layered R
In the case of an AM disc, the recording layer 17 on the read surface 19 side
Can be composed of a triple layer including the phase change recording material layer. In this case, the layer 17 arranged on the opposite side from the reading surface 19 does not need to be an information recording layer, and may be a simple dummy layer.

The optical disc 10 is a single-sided read type dual layer R
In the case of an AM / ROM disc, the two recording layers 17 are
One phase change recording layer (back side from the reading surface 19; for reading and writing) and one semitransparent metal reflection layer (reading surface 19
The front side when viewed from the side; only for playback).

When the optical disk 10 is a write-once DVD-R, polycarbonate is used as the substrate, gold is used as the reflecting film (not shown), and ultraviolet curable resin is used as the protective film (not shown). In this case, an organic dye is used for the recording layer 17. As this organic dye, cyanine, squarylium, croconic, triphenylmenthane dye, xanthene, quinone dye (naphthoquine, anthraquinone, etc.), metal complex dye (phthalocyanine, porphyrin, dithiol complex, etc.) and others can be used. is there.

For writing data to such a DVD-R disc, for example, the output is 6 to 12 m at a wavelength of 650 nm.
It can be performed using a semiconductor laser of about W.

The optical disk 10 is a single-sided read type dual layer R
In the case of an OM disc, the two recording layers 17 can be composed of one metal reflective layer (the back side when viewed from the read surface 19) and one semitransparent metal reflective layer (the front side when viewed from the read surface 19).

Read-only DVD-ROM disc 1
In the case of 0, a pit train is formed in advance on the substrate 14 by a stamper, a reflective layer of metal or the like is formed on the surface of the substrate 14 on which the pit train is formed, and this reflective layer is used as the recording layer 17. . In such a DVD-ROM disc 10, normally, no groove is provided as a recording track, and a pit row formed on the surface of the substrate 14 functions as a track.

In the various optical discs 10 described above, read-only ROM information is recorded in the recording layer 17 as an embossed signal. On the other hand, the substrate 14 having the recording layer 17 for reading and writing (or for write once) is not engraved with such an emboss signal, but instead is engraved with a continuous groove groove. A phase change recording layer is provided in the groove. In the case of a read / write DVD-RAM disc, the phase change recording layer in the land portion is also used for information recording in addition to the groove.

When the optical disk 10 is a single-sided reading type (whether the recording layer is one layer or two layers), the substrate 14 on the back side as viewed from the reading surface 19 need not be transparent to the reading / writing laser. In this case, the label may be printed on the entire surface of the back substrate 14.

The DVD digital video recorder, which will be described later, uses a D-RAM disc (or a DVD-RW disc) for repetitive recording / reproducing (reading / writing) and D
One-time recording / repeating playback for VD-R discs and D
The VD-ROM disc can be configured to be repeatedly played back.

FIG. 14 shows a hierarchical structure of information included in the video object set VTSTT_VOBS of FIG.

As shown in FIG. 14, each cell 84 is composed of one or more video object units (VOBU) 85. And each video object unit 8
5 is configured as an aggregate (pack row) of a video pack (V pack) 88, a sub-picture pack (SP pack) 90, and an audio pack (A pack) 91, which starts with a navigation pack (NV pack) 86. ing.
That is, the video object unit VOBU85
Is defined as a set of all packs recorded from one navigation pack 86 to immediately before the next navigation pack 86.

These packs are the minimum unit for performing data transfer processing. Further, the minimum unit for performing logical processing is a cell unit, and the logical processing is performed in this cell unit.

The navigation pack 86 is incorporated in the video object unit VOBU85 so that any angle change (non-seamless reproduction and seamless reproduction) can be realized.

Video object unit VOBU
The playback time of 85 is the video object unit VOB
This corresponds to the reproduction time of the video data composed of one or more video groups (group of pictures; GOP for short) included in U85, and the reproduction time is 0.4 seconds to 1.
It is set within the range of 2 seconds. 1 GOP is screen data that is normally about 0.5 seconds according to the MPEG standard and is compressed so as to reproduce about 15 images during that time.

Video object unit VOBU85
Contains video data, a GOP (conforming to the MPEG standard) including a video pack 88, a sub-picture pack 90 and an audio pack 91 is arranged to form a video data stream. However, regardless of the number of GOPs, the video object unit VOBU85 is defined on the basis of the reproduction time of the GOP, and the navigation pack 8 is always provided at the head of the video object unit VOBU85, as shown in FIG.
6 are arranged.

Incidentally, even in the reproduction data of only audio and / or sub-picture data, the reproduction data is constituted with the video object unit VOBU85 as one unit. For example, if the video object unit VOBU 85 is composed of only the audio pack 91 with the navigation pack 86 at the head, the video object unit V to which the audio data belongs, as in the case of the video object VOB 83 of the video data.
The audio pack 91 to be reproduced within the reproduction time of the OBU 85 is the video object unit VOBU.
It is stored in 85.

By the way, a VO having a structure as shown in FIG.
In the DVD video recorder capable of recording the video title set VTS including BS82 on the optical disc 10, this VTS
There may be a case where it is desired to edit the recorded contents after recording the TS. In order to meet this requirement, a dummy pack 89 can be inserted into each VOBU 85 as appropriate. The dummy pack 89 can be used when recording the editing data later.

As shown in FIG. 14, the video object set (VTSTT_VOBS) 82 is defined as a set of one or more video objects (VOB) 83. The video object VOB83 in the video object set VOBS82 is used for the same purpose.

The VOBS 82 for a menu is usually composed of one VOB 83, and a plurality of menu screen display data is stored therein. On the other hand, the VOBS 82 for the title set is usually composed of a plurality of VOBs 83.

Here, a VOB forming the video object set VTSTT_VOBS 82 for the title set.
If a concert video of a certain rock band is taken as an example, 83 can be considered to correspond to video data of the performance of the band. In this case, by designating VOB 83, it is possible to reproduce the concert performance music, for example, the third music of the band.

Further, the VOB 83 forming the menu video object set VTSM_VOBS stores the menu data of all the songs of the concert performance songs of the band, and according to the display of the menu, a specific song,
For example, an encore performance song can be reproduced.

In a normal video program, one VOB 83 can constitute one VOBS 82. In this case, one video stream is one VO
It will be completed at B83.

On the other hand, for example, in the case of an animation collection of multiple stories or a movie in the omnibus format, one VO
A plurality of video streams (a plurality of program chains PGC) can be provided in the BS 82 corresponding to each story. In this case, each video stream is stored in the corresponding VOB 83. At that time, the audio stream and the sub-picture stream related to each video stream are also completed in each VOB 83.

The VOB 83 has an identification number (IDN # i;
i = 0 to i) is added, and the VO is identified by this identification number.
B83 can be specified. The VOB 83 is composed of one or a plurality of cells 84. Although a normal video stream is composed of a plurality of cells, a menu video stream may be composed of one cell 84.
An identification number (C_IDN # j) is attached to each cell 84 as in the case of the VOB 83.

FIG. 15 shows a pack-type data string (pack string) obtained after being read from the optical disk (DVD-ROM or DVD-RAM) 10 and subjected to signal demodulation / error correction in a disk drive (not shown). Is illustrated. This pack row is composed of a navigation pack (control pack) 86, a video pack 88, a dummy pack 89, a sub-picture pack 90, and an audio pack 91. All of these packs are made up of data in units of 2 kbytes, like the logical sector in FIG.

The navigation pack 86 includes a pack header 110, reproduction control information / presentation control information (PCI) packet 116, and data search information (DS).
I) It contains packet 117. PCI packet 11
6 includes a packet header 112 and PCI data 113, and the DSI packet 117 includes a packet header 11
4 and DSI data 115. PCI
The packet 116 includes control data used when switching the non-seamless angle, and the DSI packet 117 includes control data used when switching the seamless angle.

Here, the angle switching means changing the angle at which the subject image is viewed (camera angle). In the example of a rock concert video, in a performance scene (same event) of the same song, a scene mainly captured by vocalists, a scene mainly captured by guitarists,
This means that you can see scenes from various angles, such as scenes captured mainly by drummers.

[0118] Angles can be switched (or changed) when the angle can be selected according to the viewer's preference and when the same scene is automatically changed and repeated in the story flow. (If the software producer / provider configured the story as such; or if the user of the DVD video recorder described below made such an edit).

When selecting an angle,
There are the following: In other words, in the case of non-seamless non-seamless playback where the angle changes when returning to the beginning of the same scene (for example, the scene at the moment when the boxer inserts a counter punch, the camera angle changes to another angle and the counter starts to be launched again) If it is played back) and the scene changes from one scene to the next, the angle changes. For example, in the case of seamless playback that is continuous in time (for example, at the moment the boxer puts in the counter and the punch comes in, the camera angle changes to another angle and the counter is eaten). (When the scene where the opponent blows is played continuously in time)
There is.

The video pack 88 has a pack header 881.
And a video packet 882. The dummy pack 89 is composed of a pack header 891 and a padding packet 890, and the padding packet 890 is composed of a packet header 892 and padding data 893. However, padding data 893 contains invalid data.

The sub-picture pack 90 has a pack header 901.
And a sub-picture packet 902. The audio pack 91 is composed of a pack header 911 and audio packets 912.

The video packet 882 of FIG. 15 includes a packet header (not shown), and a decoding time stamp (DST) and a presentation time stamp (PTS) are recorded in this packet header.
Further, each of the sub-picture packet 902 and the audio packet 912 includes a packet header (not shown), and a presentation time stamp (PTS) is recorded in these packet headers.

FIG. 16 shows the structure of one navigation pack of FIG.

That is, the 1-pack navigation pack 86 includes a 14-byte pack header 110, a 24-byte system header 111, and two packets (11
6, 117) including 2010 bytes of navigation data. The two packets forming the navigation data are the reproduction control information (PCI) packet 116 and the data search information (DSI) packet 117 mentioned in the description of FIG.

The PCI packet 116 is composed of a 6-byte packet header 112A, a 1-byte substream identifier (substream ID) 112B, and a 979-byte PCI data 113. Substream I
The data stream of the PCI data 113 is designated by the 8-bit code “00000000” of D112B.

The DSI packet 117 includes a 6-byte packet header 114A, 1-byte substream identifier (substream ID) 114B, and 101.
It is composed of 7-byte DSI data 115. 8-bit code “0000000” of substream ID 114B
1 ”designates the data stream of the DSI data 115.

The data length of one pack of the navigation pack 86 constructed in this way is equal to the logical sector 1 of FIG.
This corresponds to 2048 bytes (2 kbytes).

The pack header 110 and the system header 111 in FIG. 16 are defined by the MPEG2 system layer. That is, the pack header 110 stores the pack start code, the system clock reference (SCR), and the information of the multiplexing rate.
In 1, a bit rate and a stream ID are described.
Similarly, the packet header 112 of the PCI packet 116
Packet header 114 of A and DSI packet 117
In A, a packet start code, a packet length, and a stream ID are stored as defined in the MPEG2 system layer.

FIG. 17 shows the structure of one dummy pack shown in FIG. That is, one dummy pack 8
9 includes a pack header 891, a packet header 892 having a predetermined stream ID, and padding data 893 filled with a predetermined code. (The packet header 892 and the padding data 893 constitute the padding packet 890.) The padding data 893 of the unused dummy pack has no special meaning. The dummy pack 89 can be used as appropriate when editing the recorded contents after the predetermined recording is performed on the disc 10 of FIG.

Consider, for example, the case where a video tape recording a family trip is recorded on a DVD-RAM (or DVD-RW) disk 10 and edited by a portable video camera.

In this case, first, only the video scenes to be put together on one disc are selectively recorded on the disc 10. This video scene is recorded in the video pack 88 of FIG. Further, the voices simultaneously recorded by the video camera are recorded in the audio pack 91.

VOBU8 including this video pack 88, etc.
5 always has a navigation pack 86 at the head thereof. As shown in FIG. 15, the navigation pack 86 includes the reproduction control information PCI and the data search information DS.
Contains I. This PCI or DSI can be used to control the reproduction procedure of each VOBU (for example, it is possible to automatically connect scattered scenes or record a multi-angle scene).

After the video tape is edited and recorded on the disc 10, after-recording voices / sound effects or the like in each VOBU unit or adding background music BGM to each scene, the after-recording voice or BGM is added.
The dummy pack 89 can be recorded. Further, in the case of adding a description of the recorded contents, additional images such as additional characters and figures can be recorded in the dummy pack 89. When it is desired to insert an additional video image, the insert video can be recorded in the dummy pack 89.

The above-mentioned post-recording voice and the like are written in the padding data 893 of the dummy pack 89 used as an audio pack. In addition, the above additional explanation, etc.
It is written in the padding data 893 of the dummy pack 89 used as a sub-picture pack. Similarly, the insert video is written in the padding data 893 of the dummy pack 89 used as a video pack.

That is, the dummy pack 89 is a wild card-like pack which can be an audio pack, a sub-picture pack or a video pack depending on the purpose of use.

FIG. 18 shows a PCI packet 116 included in the navigation pack 86 arranged at the head of each VOBU 85. As shown in the figure, the PCI packet 116 is reproduction control information PCI which is navigation data for changing display contents or reproduction contents (presentation contents) in synchronization with the reproduction state of the video data in the video object unit (VOBU) 85.

Free space (recordable capacity) FR in FIG.
EE_SPACE is the same as the free capacity data in the physical format information of FIG. 11 for the unused blank disk 10. For the storage method of the free space of the disk 10, the location of the file descriptor (physical format information)
It is conceivable to store the information in the management information and the management information (VMGI_MAT). The free disk space after recording and using this disk 10 partially is FREE_SPA in FIG.
It can be written to the CE and / or the free space portion of the physical format information of FIG. 11 (here, FRE
We will write both E_SPACE and physical format information). For example, in the case of the single-sided DVD-RAM disc 10 having a capacity of 2.6 GB, information representing 2.6 GB is written in the byte positions 17 to 20 in FIG. If no recording is made on the disc 10, information indicating a value obtained by subtracting management data (including the video manager VMG) and the like from 2.6 GB is written in FREE_SPACE of FIG.

If, for example, 1 GB of video is recorded on the disk 10, the byte positions 17 to 20 in FIG.
Information is equivalent to 2.6 GB, but FREE_ in FIG.
The SPACE information is rewritten to 1.6 GB.
Such a partially recorded disc 10 is a DVD described later.
When set in the video recorder, the DVD video recorder first reads the information in byte positions 17 to 20 in FIG. 11 to detect that the set disk 10 is a 2.6 GB disk, and then in FIG. 22, FREE_SPA.
The CE information is read to detect that the free space of the set disk 10 is a 1.6 GB disk. If this disk 10 is completely erased, FREE of FIG.
_SPACE and the information of the free capacity portion of the physical format information of FIG. 11 are rewritten to be equivalent to 2.6 GB.

That is, even if the same "free space" is represented, the free space in FIG. 11 and FREE_SPACE in FIG.
Can make a difference in the content.

FIG. 29 shows the cell category C_C of FIG.
The contents of AT are shown. This cell category (C_CAT)
As shown in FIG. 29, the lower 8 bits (b0 to b7)
Indicates the number of cell commands, and the next 8 bits (b8 to b1
5) indicates the cell still time, and the next 5 bits (b16 to
b20) indicates the cell type (for example, karaoke),
The next 1 bit (b21) indicates the access restriction flag,
The next 1 bit (b22) indicates the cell playback mode (for example, moving image or still), the reserved bit is skipped, and the next 1 bit (b24) indicates the seamless angle change flag.
The next 1 bit (b25) is the system time clock ST
C discontinuity flag (whether or not STC is reset) is indicated, and the next 1 bit (b26) indicates whether the interleave placement flag (cell designated by C_PBI is in a continuous block or in an interleaved block). The next 1 bit (b27) indicates a seamless playback flag (whether or not the cell specified by C_PBI should be seamlessly played), and the next 2 bits (b2).
8 to b29) indicate the cell block type (for example, whether it is an angle block), and the last 2 bits (b30 to
b31) indicates the cell block mode (for example, whether it is the first cell in the block).

Here, the cell block mode is 00b (b
Indicates that it is not a cell in the block, 01b indicates that it is the first cell in the block, and 10b indicates that it is a cell in the block. , It is the last cell in the block when it is 11b.

Further, when the cell block type is 00b, it indicates that the cell block is not a part of the corresponding block, and it is 01
When it is b, it indicates that the corresponding block is an angle block (a block including a multi-angle cell).

If the cell block type is not 01b during the reproduction of a title including a multi-angle cell, for example, an angle mark (not shown) is kept lit.

On the other hand, if this cell block type = 01b is detected during reproduction, the angle mark (not shown) blinks (or the lighting color is changed or the shape of the angle mark is changed) indicating that the angle block is currently being reproduced. Can notify the viewer. As a result, the viewer can know that the image currently being reproduced can be reproduced at a different angle.

When the interleaved arrangement flag is 0b, it indicates that the corresponding cell is in a continuous block (a plurality of VOBUs are continuously recorded). When the interleaved arrangement flag is 1b, the corresponding cell is interleaved. Block (ILVU each containing one or more VOBUs
Is interleaved and recorded).

When the seamless angle change flag is set (= 1b), it indicates that the corresponding cell is a target for seamless reproduction, and this flag is not set (=).
0b) indicates that the corresponding cell is the target of non-seamless reproduction.

That is, the interleave arrangement flag = 1
When the seamless angle change flag = 0b in b, the non-seamless angle changeable state is set, and when the interleave arrangement flag = 1b, the seamless angle change flag = 1.
In the case of b, the seamless angle can be changed.

A media drive system having an extremely short access time (a system capable of accessing the beginning of a desired angle block within one frame period of video;
(Not necessarily limited to the optical disc drive system) is used, interleave arrangement flag = 0b,
That is, a quick angle change can be realized between a set of VOBUs (separate angle cells) that are not interleave-recorded.

Optical disc 10 having a relatively low access speed
When used as a recording medium, it is preferable to allocate one recording track of the disc for recording one interleaved block. Then jump between adjacent interleaved blocks (angle change)
Sometimes, the tracing destination of the optical head needs to be finely moved by one track in the radial direction of the disk, so that a track jump (suitable for seamless angle change) with almost no time lag becomes possible. In this case, if a track jump for one video object unit (VOBU) is performed, a maximum time lag for one rotation of the disc may occur. Therefore, the angle change accompanied by the jump in VOBU units is suitable for the non-seamless angle change.

Here, the content of the seamless angle change flag is usually determined in advance by the provider (the software producer who produces the program content of each title recorded on the optical disc 10). That is, by determining the content of the seamless angle change flag in advance, it is possible for the provider to unambiguously decide whether to make a non-seamless angle change or a seamless angle change.

However, after reading the cell data of the corresponding title set from the optical disk, the contents of the seamless angle change flag in the read data can be changed arbitrarily by the viewer (user of the DVD video recorder described later) so that the DVD video can be changed. It is possible to configure the recorder.

Since the seamless angle change flag is a flag indicating whether the angle information (not shown) written in the navigation pack 86 is a seamless angle or a non-seamless angle, the navigation pack 86 is changed when this flag is changed. It becomes necessary to correct the angle information (not shown) in (for example, change from seamless angle information to non-seamless angle information).

When the cell reproduction mode is 0b, continuous reproduction is performed in the cell, and when it is 1b, still reproduction is performed in each VOBU existing in the cell.

When the user performs recording / playback, etc., the access restriction flag can be used to prohibit direct selection by user operation. For example, by setting the access restriction flag of the cell in which the answers to the questions are recorded to 1b, it is possible to prohibit the user from pinching the answers to the questions.

The cell type can indicate the following depending on the contents of the 5 bits when the corresponding cell is created for karaoke, for example.

That is, if 00000b, the cell type is not designated, if it is 00001b, the title image of karaoke is designated, if it is 00010b, the intro of karaoke is designated, and if it is 00011b, the climax (rust).
Is designated as 00100b, the first climax singing portion is designated, and 00101b is designated as the second climax singing portion.
If it is 0b, the vocal part of the male vocal is designated,
If it is 1b, the singer part of female vocal is specified, and 0100
If it is 0b, the singing part of the mixed voice of men and women is designated, and 01
If it is 001b, the interlude (playing only the musical instrument) part is designated, if it is 01010b, the fade-in of the interlude is designated, if it is 010111b, the fade-out of the interlude is designated, if it is 01100b, the first ending performance part is designated, and if it is 01101b. The second ending performance part is designated. The content of the remaining 5-bit code can be used for other purposes.

The angle change can also be applied to the angle change of the karaoke background video. (For example, a full-length image of a singer singing a guide vocal, a close-up image of the face, a close-up image of the mouth, etc. can be seamlessly followed along the flow of karaoke music, or it can go backwards a short time to be non-seamless, and even between desired bars. The angle can be changed as desired by the viewer during repeat playback.) When the 8-bit contents of the cell still time in FIG. 29 is 00000000b, it is specified that it is not a still image, and 111111
When it is 11b, the still timeless is specified and it is 0.
In the case of 0000001b to 11111110b, the still display having the length in which the decimal number (1 to 254) designated by this content is displayed for the number of seconds is designated.

The number of cell commands indicates the number of commands to be executed at the end of reproduction of the corresponding cell.

FIG. 31 shows the disk of FIG.
The configuration of an apparatus (DVD video recorder) that records and reproduces digital moving image information at a variable recording rate by using the information having the structure described in FIG.

The apparatus main body of the DVD video recorder shown in FIG. 31 is roughly a DVD-RAM or a DVD.
-R A disk drive unit (3 that drives the disk 10 to rotate and reads / writes information from / to this disk 10
(2, 34, etc.) and the encoder unit 50 that constitutes the recording side.
And a decoder unit 60 which constitutes the reproducing side, and a microcomputer block 30 which controls the operation of the apparatus main body.

The encoder section 50 includes an ADC (analog /
Digital converter) 52, video encoder (V encoder) 53, audio encoder (A encoder)
54, a sub-picture encoder (SP encoder) 55,
The formatter 56 and the buffer memory 57 are provided.

The ADC 52 has an external analog video signal from the AV input section 42 + an external analog audio signal,
Alternatively, the analog TV signal + analog audio signal from the TV tuner 44 is input. The ADC 52 digitizes the input analog video signal with, for example, a sampling frequency of 13.5 MHz and a quantization bit number of 8 bits. (That is, each of the luminance component Y, the color difference component Cr (or Y−R) and the color difference component Cb (or Y−B) is quantized with 8 bits.) Similarly, the ADC 5
2 digitizes the input analog audio signal with a sampling frequency of 48 kHz and a quantization bit number of 16 bits.

When analog video signals and digital audio signals are input to the ADC 52, AD
C52 allows the digital audio signal to pass through.
(The contents of the digital audio signal may not be modified, and only the jitter associated with the digital signal may be reduced, or the sampling rate or the number of quantization bits may be changed).

On the other hand, when a digital video signal and a digital audio signal are input to the ADC 52, AD
The C52 allows a digital video signal and a digital audio signal to pass through (these digital signals may be subjected to jitter reduction processing, sampling rate changing processing, etc. without changing the contents).

The digital video signal component from the ADC 52 is sent to the formatter 56 via the video encoder (V encoder) 53. The digital audio signal component from the ADC 52 is sent to the formatter 56 via the audio encoder (A encoder) 54.

The V encoder 53 has a function of converting an input digital video signal into a digital signal compressed at a variable bit rate based on the MPEG2 or MPEG1 standard.

Further, the A encoder 54 has a function of converting the input digital audio signal into a digital signal (or linear PCM digital signal) compressed at a fixed bit rate based on the MPEG or AC-3 standard. .

When a DVD video signal having a data structure as shown in FIGS. 14 and 15 is input from the AV input section 42 (for example, a signal from a DVD video player with an independent output terminal of a sub video signal), or A DVD video signal with a data structure is broadcast, which is the TV tuner 4
In the case of being received at 4, the sub video signal component (sub video pack) in the DVD video signal is input to the sub video encoder (SP encoder) 55. The sub-picture data input to the SP encoder 55 is arranged in a predetermined signal form and sent to the formatter 56.

The formatter 56 has a buffer memory 57.
Using as a work area, the specified signal processing is performed on the input video signal, audio signal, sub-picture signal, etc., and the recording conforms to the format (file structure) described with reference to FIGS. The data is output to the data processor 36.

Here, a brief description will be given of the contents of standard encoding processing for creating the recording data. That is, when the encoding process is started in the encoder unit 50 of FIG. 31, parameters necessary for encoding the video (main image) data and the audio data are set. Next, the main video data is pre-encoded using the set parameters, and the distribution of the optimum code amount for the set average transfer rate (recording rate) is calculated. In this way, the main video is encoded based on the code amount distribution obtained by the pre-encoding. At this time, audio data encoding is also executed at the same time.

As a result of the pre-encoding, if the data compression amount is insufficient (if the desired video program does not fit on the DVD-RAM disk or DVD-R disk to be recorded), there is an opportunity to pre-encode again. If the source of the recording is a repeatable source, such as a videotape or video disc, then a partial re-encoding of the main video data is performed, and the re-encoded part of the main video data is pre-encoded earlier. The replaced main video data portion is replaced. By such a series of processing, the main video data and the audio data are encoded, and the value of the average bit rate required for recording is significantly reduced.

Similarly, the parameters necessary for encoding the sub-picture data are set, and the encoded sub-picture data is created.

The main video data, audio data and sub-video data encoded as described above are combined and converted into the structure of the video title set VTS.

That is, main video data (video data)
The cell is set as the minimum unit of, and cell reproduction information (C_PBI) as shown in FIG. 28 is created. Next, the configuration of cells constituting the program chain as shown in FIG. 8, attributes of main video, sub-video and audio, etc. are set (some of these attribute information are obtained when each data is encoded). Information is used), information management table information including various information (VMGI_MAT in FIG. 22)
Or VTSI_MAT) of FIG. 24 is created.

The encoded main video data, audio data and sub video data are subdivided into packs of a fixed size (2048 bytes) as shown in FIG.
Dummy packs are appropriately inserted into these packs.
In packs other than the dummy pack, PTS may be used as appropriate.
Time stamps such as (presentation time stamp) and DTS (decode time stamp) are described. For the PTS of the sub-picture, a time arbitrarily delayed from the PTS of the main picture data or audio data in the same reproduction time zone can be described.

Each data cell is arranged while the navigation pack 86 is arranged at the head of each VOBU 85 so that the data can be reproduced in the order of the time code of each data, and is composed of a plurality of cells as shown in FIG. VO
B83 is configured. A VOBS 82 in which one or more VOBs 83 are collected is formatted in the structure of the VTS 72 in FIG.

When the DVD reproduction signal is digitally copied from the DVD video player, the contents of the cell, program chain, management table, time stamp and the like are determined from the beginning, and it is not necessary to create them again. (However, to configure the DVD video recorder so that the DVD playback signal can be digitally copied,
Electronic watermarks and other copyright protection measures must be taken. ) The disc drive unit for reading / writing information (recording and / or reproducing) from / to the DVD disc 10 includes a disc changer unit 100, a disc drive 32, a temporary storage unit 34, and a data processor 36.
And a system time counter (or system time clock; STC) 38.

The temporary storage unit 34 is used for the disk drive 32.
Buffering a fixed amount of data (data output from the encoder unit 50) written to the disk 10 via the disk 10 or data reproduced from the disk 10 via the disk drive 32 (input to the decoder unit 60). Data) to be buffered.

For example, when the temporary storage unit 34 is composed of a semiconductor memory (DRAM) of 4 Mbytes, an average of 4 M
It is possible to buffer recording or reproducing data for about 8 seconds at a recording rate of bps. When the temporary storage unit 34 is composed of a 16-Mbyte EEPROM (flash memory), it is possible to buffer record or reproduction data for about 30 seconds at an average recording rate of 4 Mbps. Further, when the temporary storage unit 34 is composed of a 100-Mbyte ultra-compact HDD (hard disk), it is possible to buffer the recorded or reproduced data for 3 minutes or more at an average recording rate of 4 Mbps.

[0229] Temporary storage section 34 is used for disc 1 during recording.
When 0 is used up, it can be used for temporarily storing recording information until the disc 10 is replaced with a new disc.

Further, when the high speed drive (double speed or more) is adopted as the disk drive 32, the temporary storage section 34 temporarily stores the data read extra than the normal drive within a fixed time. Is also available. If the read data at the time of reproduction is buffered in the temporary storage unit 34, the reproduction data buffered in the temporary storage unit 34 is switched and used even when an optical pickup (not shown) causes a reading error due to vibration shock or the like. This makes it possible to prevent playback video from being interrupted.

Although not shown in FIG. 31, if the DVD video recorder is provided with an external card slot, the EE
PROM can be sold separately as an optional IC card.
If the DVD video recorder is provided with an external drive slot or a SCSI interface, the above HDD can be sold separately as an optional expansion drive.

Under the control of the microcomputer block 30, the data processor 36 shown in FIG. 31 supplies the DVD recording data from the encoder section 50 to the disc drive 32 and the DVD reproduced from the disc 10.
The playback signal is taken out from the drive 32, or the disc 1
Management information recorded in 0 (directory record of FIG. 13, VMGI_MAT of FIG. 22, VTSI_M of FIG. 24)
(AT, etc.) is rewritten, or the data (file or VTS) recorded on the disk 10 is deleted.

The microcomputer block 30 has M
It includes a PU (or CPU), a ROM in which a control program and the like are written, and a RAM that provides a work area necessary for executing the program.

The MPU of the microcomputer block 30 uses the RAM as a work area in accordance with the control program stored in the ROM to detect the free space, the recording amount (recording pack number), the remaining amount, which will be described later. Warnings, recording mode change instructions, and other processing are executed.

Of the execution results of the MPU 30, the contents to be notified to the user of the DVD video recorder are displayed on the display unit 48 of the DVD video recorder or on the monitor display as an on-screen display.

It should be noted that the MPU 30 includes the disk changer unit 100, the disk drive 32, the data processor 36,
The timing for controlling the encoder unit 50 and / or the decoder unit 60 can be executed based on the time data from the STC 38 (the recording / playback operation is normally executed in synchronization with the time clock from the STC 38). However, other processing may be executed at a timing independent of the STC 38).

The OSD data output from the MPU 30 is input to the separator 62 of the decoder unit 60, passes through the V decoder 64 (is not particularly decoded) and is input to the video processor 66. Then this O
SD data is superimposed on the main video, which is the AV output unit 46.
Is supplied to an external monitor TV connected to. Then, the warning text is displayed together with the main video.

A printer interface P1 is connected to the MPU 30. Further, the printer P2 is connected to the printer interface P1. The printer P2 prints out an image based on various data reproduced from the optical disk 10 to a predetermined place (optical disk, label attached to the optical disk, cartridge containing the optical disk, etc.).

FIG. 32 shows an example of the appearance of the apparatus main body 200 of the DVD video recorder shown in FIG. 31 and an example of its front panel.

When the user presses the open / close button 5g of the remote controller 5 which will be described later with reference to FIG. 33, the disc tray inlet 202 of FIG. 32 opens to the front.

On this disc tray, D used for recording
A VD-RAM or DVD-RW disk (disk with cartridge) 10 or DVD-R disk (bare disk) 10 is set.

Subsequently, when the user presses the open / close button 5g of the remote controller 5, the disc tray inlet 202 is closed, and the disc (for example, DVD-RW) 10 set in the tray is set in the main body 20 of the apparatus.
It is drawn into the disk drive 32 in 0.

Then, the disk drive 32 automatically starts up, and first, the physical format information (including disk structure data, blank disk free space data, etc.) of FIG. 11 is read by the MPU 30, and then FIG.
2 video manager information management table (including information FREE_SPACE indicating substantial free space and others)
And the video title set information management table of FIG. 24 (PLA indicating whether or not a particular title set has been reproduced).
Y_END Flag, ARCHIVE Flag indicating whether a particular title set is in a permanent storage state, etc.) is read by the MPU 30.

Then, in the case where the set disk 10 is an unused DVD-RW disk (or DVD-RAM disk), in the DVD video recorder display section (liquid crystal or fluorescent display panel) 48 of FIG.
The item “D-RW” is conspicuously displayed. Also, the recording time is displayed as 00 (hour): 00 (minute): 00 (second), and the recording title / chapter is also displayed as 00-00 (If recorded even once, this recording title /
The chapter display changes like 01-01).

If the device default or user setting is recording mode = MPEG2 and average recording bit rate = 4 Mbps, the display unit 48 displays
The items "MPEG2" and "4 Mbps" are displayed conspicuously.

Further, when recording on the set disk 10 progresses and the remaining recordable time on the disk 10 becomes short (for example, 5 minutes left), the MPU 30 detects this and the display unit 48 displays The "DISK TO BECHANGED" item prompting you to replace the disc is conspicuously displayed.

The front panel of the DVD video recorder main body 200 further has a power switch button and an open / open button.

It is assumed that the disc changer unit 100 of FIG. 31 is not built in (the disc changer unit 100 is connected to the device main body 200 of FIG. 32 by an SCSI cable or the like as an optional external device). In this case, the “DISK TO BE C” on the display unit 48 is displayed shortly before the disk 10 set in the apparatus main body is used up during recording.
"HANGED" starts to flash or blink. After that, when the remaining capacity of the disc 10 becomes zero, the recording is automatically continued for one or more DVD-RW discs 10 set in the external disc changer unit 100.

Alternatively, it is possible to prepare two or more DVD video recorders, connect each MPU 30 with a communication cable in a daisy chain, and perform relay recording using two or more DVD video recorders. In this case, it is also possible to say that "the first recorder records MPEG2 / average bit rate 4 Mbps for 1 hour and the second recorder records MPEG2 / average bit rate 2 Mbps for 2 hours".

When relay recording is performed by the plural DVD video recorders as described above, "MPA on recorder A" is used.
