2. Description of the Related Art In recent years, a next-generation disk medium having the same diameter as a conventional CD (compact disk) but having a storage capacity several times to several ten times that of a CD has been put into practical use. As the next-generation disc medium, for example, a DVD
-ROM disc (DVD Specifications for Read-Only
There is a read-only optical disc compliant with Disc, and as a recordable and reproducible disc, a DVD-RW disc (re-recordable disc compliant with DVD Specifications for Rewritable Disc) and a DVD-RAM disc (DVD Specifications for Random Access Memory) Di
There are rewritable discs that are sc compliant). In addition, a standard for recording video data on a DVD-RW disc or a DVD-RAM disc has been established.
By utilizing the large capacity, a method of recording a high-quality moving image and still image, performing various editing, and playing back is provided.

The above-mentioned DVD-RW disc or DVD
-Standard for recording video data on a RAM disk (hereinafter abbreviated as DVD-RW / RAM disk) (VIDEO
According to the RECORDING standard (hereinafter abbreviated as DVD-VR), video data is recorded as a VOB (Video Object), and original management data for reproducing all VOB groups in the recording order, an original PGC (Orig).
internal program chain) and user-defined management data for playing all or part of the VOB selected by the user in an arbitrary order, user-defined PGC (User Defined P
GC) is defined. There can be only one original PGC and multiple user-defined PGCs on the disc. Therefore, the user can perform the favorite reproduction by using the user-defined PGC edited according to the taste.

In addition, a standard document ("DVD Specifications for
Rewritable / Re-recordable Discs, Part3 VIDEO RECORDI
NG, Version 1.0 "), a plurality of files are recorded as files on the DVD-RW / RAM in the DVD-VR standard. The structure is shown in FIG. 11. The DVD_RTAV directory is under the root directory. , VR_ for recording all recording / playback management data such as original PGC and user-defined PGC underneath.
Record the MANGR.IFO file. Also, the moving image data is stored in the VR_MOVIE.VRO file, the still image data is stored in the VR_STILL.VRO file, and the additional audio data accompanying the still image is VR_AUDI.
It is recorded in the O.VRO file.

As described above, since the actual reproduction data and the recording / reproduction management data are recorded separately, an arbitrary reproduction procedure can be constructed by the user-defined PGC without changing the reproduction data. In addition, VR_STI
Each still image data in the LL.VRO file is MPEG
It is recorded as an MPEG intra image conforming to the Video standard.

FIG. 12 is a structural conceptual diagram of the original PGC. When recording moving image data on a disc according to the DVD-VR standard, for example, when recording one TV program,
The series of moving image data is stored in one program (Pr
The program is composed of one or a plurality of cells. In general,
The program is composed of a plurality of cells when the program is paused during recording, or when the middle part of the program is deleted by editing after recording.

Each cell is associated with one VOB. Each VOB is a unit which is recorded as a program stream conforming to the MPEG-2 system and continuously reproduced. The program and cell structure is the original PGC recording / playback management data, and the VOB group is the moving image data itself. The program first recorded on the disc is Program 1 in FIG. 12, and each time the program is additionally recorded, the program 2, 3, ... To play the original PGC,
This is equivalent to reproducing all the programs recorded on the disc in the order of program numbers, that is, in the order of recording. It is also possible to specify and reproduce a specific program on the original PGC.

On the other hand, FIG. 13 shows a conceptual diagram of the structure of the user-defined PGC. VO recorded as original PGC
An arbitrary part of the B group is registered as a cell for the user-defined PGC to configure the user-defined PGC. Each cell refers to all or part of any VOB. For example, commercials of VOB recorded as original PGC or unnecessary scenes may be cut, or two or more programs (prog
It is suitable for applications such as connecting and playing a part of ram).

Reproduction of the newly defined user-defined PGC corresponds to continuous reproduction of all cells in the PGC. There is no program hierarchy in the user-defined PGC. That is, it can be interpreted that the user-defined PGC itself corresponds to one program called the original PGC. Table 1 shows specific definition contents of original and user-defined PGC information (PGCI).

[0010]

[Table 1] As shown in Table 1 above, PGCI is PGC_GI indicating general information of PGC, one or more PGIs (in the case of original PGC, not defined by user-defined PGC) defining auxiliary information of each program, in PGC. Search pointer CI_SRP of each cell information and each cell information M_C
I (for a moving picture cell; S_CI for a still picture cell).

Next, the contents of each element in Table 1 will be described.
In PGC_GI, PG_Ns that stores the number of programs in PGC and CI_S that stores the number of CI_SRP.
RP_Ns is defined. For user-defined PGC,
Since there is no program, PG_Ns is zero.

There are as many PGIs as indicated by PG_Ns. In each PGI, C that indicates the number of cells in the program
_Ns, primary text information (PRM_TXTI) that records text information related to the program, item text information (separately recorded as a separate data structure in VR_MANGR.IFO instead of PGCI) related to the program, and search pointer number (IT_T
XT_SRPN), representative still image information (REP_PICTI) that specifies the position of a still image representing a program, and the like are defined.

There are as many CI_SRPs as indicated by CI_SRP_Ns. Each CI_SRP is composed of the head address CI_SA of the cell information CI. M_CI consists of cell general information M_C_GI and zero or more cell entry point information M_C_EPI. In M_C_GI,
Cell type C_TY, number of cell entry points C_
EPI etc. are defined. In M_C_EPI, the entry point type EP_TY (A and B, A is PRM)
_TXTI not present, B has PRM_TXTI), entry point playback time EP_PTM, and primary text information (PRM_T) regarding the entry point.
XTI) is defined.

Here, the entry point is a structure for designating an arbitrary time within the cell and enabling access to a program or an arbitrary intermediate point of the cell. 12 and 13 show examples of entry points (arrows indicated by EP) designated in the cell.

When reproducing a still image cell,
S_CI is used instead of M_CI (the contents of S_CI are omitted here). Therefore, the original PG
When a moving image and a still image are recorded on C, they are mixed for each cell. On the user-defined PGC, it is possible to mix moving picture cells and still picture cells for each cell.

A function of reproducing three types of data in association with each other is desired, but conventionally, there is no method of integrally recording and reproducing these three types of data on one medium based on a single standard. .

The second problem is that the moving picture data and the still picture data are mixed on the original PGC and cannot be handled separately from the viewpoint of the user. The third problem is that the unit of editing is a cell, not a program or song that is familiar to the user. The fourth problem is that the supported still image format is an MPEG intra image instead of the currently commonly used JPEG. The fifth problem is that if there is no hierarchy above the program on the original PGC, such as groups, and the user has recorded many programs, the original PG
It is difficult to access a specific program on C.

Next, the concept of the moving picture program set (video program set), audio program set and still picture program set of the present invention will be described with reference to FIG. Each program set has a structure for managing moving image data, audio data, or still image data recorded on a disc in the order of recording.

In the video program set (corresponding to V_PR_SET in FIG. 1) shown in FIG. 4A, a plurality of video programs (moving image programs) are recorded in the order of recording,
The video program number (V_PRN) is assigned in the order of recording. For example, V_PR # 1 is recorded under the V_PR_SET directory as V_pr1.dat.

The recorded video programs are grouped in the order of recording and can belong to one video group. The video group is suitable for grouping and managing a plurality of programs recorded by the user. Here, as an example, 2 related to an event
One video program V_PR # 1 and V_PR # 2 belong to the first group V_GR # 1 and three video programs V_PR # 4 and V_ related to another event
PR # 5 and V_PR # 6 are connected to the second group V_GR # 2
Belong to. The video program V_PR #
Although 3 is specified in V_GR # 0 of group number 0, if this V_GR # 0 is specified, it is treated as an independent program that does not belong to any group and is independent of the preceding and succeeding programs. For example, if the television broadcast is simply air-checked and recorded on a daily basis, the group number 0 is designated. Information necessary for grouping and reproducing video programs is recorded in V_PR_IFOT.

As shown in FIG. 4B, an audio program set (corresponding to A_PR_SET in FIG. 1)
A plurality of audio programs are recorded in the recording order, and an audio program number (A_PRN) is assigned in the recording order. For example, A_PR # 1 is A_PR1.da
It is recorded under the A_PR_SET directory as t.

The recorded audio programs are grouped in the order of recording and can belong to one audio group. The audio group is suitable for grouping and managing a plurality of programs recorded by the user. Here, as an example, three programs A_PR # 1 and A_P related to a certain music album are used.
R # 2 and A_PR # 3 belong to the first group A_GR # 1 and three programs A_PR # 4, A_PR # 5 and A_PR # 6 related to different music albums belong to the second group A_GR # 2. ing.

In the case of an audio program,
Due to its nature, it is better not to specify the group number 0. This is because most audio programs are copied from existing media, and it is easier to understand if a group is composed of multiple songs (programs) (a hierarchical structure of groups / programs). This is because.

The programs in the audio group include
Track numbers are assigned in order of recording, with the first program in the group being 1. The user can access each program in the audio program set by audio group number and track number. Information required for grouping and playing audio programs is A
Recorded in _PR_IFOT.

As shown in FIG. 4C, a plurality of still picture programs are recorded in the order of recording in the still picture program set (corresponding to S_PR_SET in FIG. 1) and still picture program numbers (S_PRN) are recorded. Shaken in order. For example, S_PR # 1 is S_PR1.jpg
It is recorded under the PR_SET directory.

The recorded still picture programs are grouped in the order of recording and can belong to one still picture group. The still image group is suitable for grouping and managing a plurality of programs recorded by the user. Here, as an example, three programs S_PR # 1, S_PR # 2, and S_PR # 3 related to a certain trip are used.
Belong to the first group S_GR # 1 and three programs related to different trips S_PR # 4 and S_PR #
5 and S_PR # 6 belong to the second group S_GR # 2.

In the case of a still picture program, it is better not to specify the group number 0 because of its nature. This is because in the case of still images, it is rare that only one image is recorded, and it is almost the case that several images are continuously shot or recorded, so a hierarchical structure of group / still image group is always used. This is because it is easier for the user to understand. Of course, the group number 0 may be designated. Information necessary for grouping and reproducing still picture programs is recorded in S_PR_IFOT.

Next, a configuration example of the play list will be described with reference to FIG. FIG. 5 shows an example of the structure of a playlist. FIG. 1A is an example of a playlist that reproduces all or part of a plurality of video programs (moving image programs). When playing a part of the video program, the Start Address and End Ad in Table 5 are used.
The section to be reproduced is designated by the address.

Each video program belongs to one user-defined program. Each user-defined program has a user-defined program number UD_PRN in the order of reproduction.
(User Defined Program number) is assigned. Figure 5
In the example of (A), the whole video program V_PR # 2 and a part of V_PR # 4 are reproduced as UD_PR # 1, and each part of the video programs V_PR # 6 and V_PR # 1 are reproduced as UD_PR # 2. It

FIG. 5B shows an example of a play list in which the play order of a plurality of audio programs is changed and played. Although not shown, it is also possible to set to reproduce a part of the program as in the case of FIG. Each program is a user-defined program and UD_PRN
Is shaken. In the example of FIG. 5B, audio programs A_PR # 3, A_PR # 4, A_PR # 1 and A_
UD_PR # 1, UD_ for each program of PR # 2
PR # 2, UD_PR # 3 and UD_PR # 4 are allotted. Although not shown, it is possible to include a plurality of audio programs in one user-defined program (corresponding to linking of songs).

FIG. 5C shows an example of a playlist for connecting and reproducing programs for video (moving picture), audio and still picture. In this example, UD_P for each program
An R number is assigned, and each program is played as a user-defined program.

FIG. 5D shows an example of a playlist for simultaneously reproducing the audio program and a plurality of still picture programs. In this example, one audio program A
_PR # 1 and four still image programs S_PR # 1 to S
By shaking one UD_PR # 1 as one user-defined program with _PR # 4 as one lump, four still images are sequentially reproduced during the reproduction time of the audio program A_PR # 1.

Although not shown in FIG. 5, it is naturally possible to create another type of playlist by using any combination of (A) to (D). All playlist information is recorded in PR_IFOT.

Next, an embodiment of the recording method of the present invention will be described. FIG. 6 shows a flowchart of an embodiment of the recording method according to the present invention. In the figure, the user first selects which of the video (moving image), audio, and still image programs is to be recorded (step S1). Then, the recording of the data of the selected program is started by the user's start instruction (step S2). continue,
The recording device stores a certain amount of input data to be recorded, encodes it as necessary, formats it into a predetermined format, and records it on a recording medium (step S3).

Subsequently, it is determined whether or not the input data to be recorded is still image data (step S4), and when it is not still image data, that is, when it is video data (moving image data) or audio data, recording ends. Until that is done, recording of a certain fixed amount of input data is repeated at step S3 (steps S5, S3,
4). In the case of a still image, step S3 is performed only once for one program of still image data (one image). When the recording is completed, the original management data X_PR_IFO (X is any one of V, A, and S) is recorded on the recording medium based on the recording result (step S6).

When already-encoded data, for example, compression-coded data is input, the encoding process is bypassed. When it is determined in step S4 that the recording data is still image data, the process bypasses step S5 and proceeds to step S6. Based on the recording result, S_PR_I which is the original management data.
The FO is recorded on the recording medium.

When it is determined in step S4 that the recording data is still image data, the reason for not determining the end of recording in step S5 is that in the case of audio data or video data, recording is performed after the user instructs recording start. While it is common to continue recording until the end is instructed, in the case of still image data (when recording one still image program), after the user instructs the start of recording,
This is because it is not necessary to wait for a recording end instruction because the recording is completed when the still image data is recorded.

Next, an example of a playlist creating / updating method in the recording method according to the present invention will be described with reference to the flowchart shown in FIG. User can play the playlist (P
L) is newly created or a new user-defined program (UD_PR) is added to the existing PL (step S11), and subsequently, a mode (UD_PR_mode) of the user-defined program is selected (step S1).
2).

Next, the value of the selected user-defined program mode (UD_PR_mode) is "011b".
It is determined whether or not (composed of audio and still image) (step S13). If it is other than "011b", select a program to be registered in the playlist, which is one of video (moving image), audio, and still image (step S1.
4) If the selected program is video (video) or audio, specify the start point and end point as necessary,
If the selected program is a still image, the display mode (Display_mode) and the display period (Display_duration) are designated (step S15).

On the other hand, in step S13, UD_PR_mo
When it is determined that the value of de is '011b' (consisting of audio and still image), an audio program is selected, and a start point and an end point are designated if necessary (step S16), and then reproduced at the same time. The still image program to be selected is selected, and the display mode (Display_mode) and the display period (Display_duration) are designated (step S17).

As described above, one user-defined program (U
The setting of D_PR) is completed. When the setting of another user-defined program (UD_PR) is continued (No in step S18), the process returns to step S12.
When the creation / editing of all playlists is completed (Yes in step S18), PL_IFO is recorded or updated in the recording medium (step S19), and the process is ended. Although not shown, it is also possible to modify (edit) an existing playlist user-defined program by a similar method.

Next, an embodiment of the recording apparatus of the present invention will be described. FIG. 8 shows a block diagram of an embodiment of a recording apparatus according to the present invention. This recording device is a recording device related to FIG. 6 and FIG. 7, and assumes an optical disc as a recording medium. In FIG. 8, video data (moving image data), audio data, and still image data are input to a video encoder 11, an audio encoder 12, and a still image encoder 13, respectively, and stored and encoded as needed. Each data extracted from the video encoder 11, the audio encoder 12, and the still image encoder 13 is supplied to the formatter 14 and converted into a predetermined format as a file in program units, and then a signal suitable for recording by the disc writing unit 17. It is converted into a form and recorded on the optical disc 20 using the optical head 19.

When the recording of the above-mentioned three kinds of contents is completed, the original management data is formed on the management data memory 16 based on the recording result, which is also recorded on the optical disk via the disk writing section 17 and the optical head 19. 20. As described above, this original management data is used for audio data for separately managing each program group of three types of contents, reproducing each program group in the recording order, and managing by dividing into groups. Management data for video data and still image data.

For all of the above processing, the host MPU
Control from 15 is done. When the video data includes audio, audio recording can be simultaneously processed via the audio encoder 12. Generally, video data and audio data are multiplexed and recorded on the optical disc 20.

The formatter 14 is used when the still image data input from the still image encoder 13 is in a format other than JPEG, or when the still image encoder 1 is used.
When an analog still image signal is input without passing through 3, the input signal is converted into a JPEG image and formatted.

On the other hand, when creating a playlist, 3
Two encoders 11, 12 and 13 and a formatter 14
Does not operate, the playlist information is created by the processing on the user interface circuit 18, the host MPU 15, and the management data memory 16, and the disc writing unit 17
And is recorded on the optical disc 20 via the optical head 19. As described above, in the present embodiment, three types of contents of video data (moving image data), audio data, and still image data are recorded on the same optical disc 20, and the reproduction order described with reference to FIG. Since the designated playlist is also recorded, it is possible to obtain the optical disc 20 capable of integrally reproducing the recorded three types of contents by the playlist.

Since the still image data to be recorded is compatible with JPEG which is generally used at present, the optical disk 20 which can easily capture a still image from another system and output it to another system. Can be obtained. In addition, since the original management data (program list) is recorded so as to have a group hierarchy, the content management on the optical disk 20 can be separated for each content by the user, and it is easy to understand, and the optical disk is a large-capacity recording medium. Even when a large amount of data is recorded on the optical disc 20, it is possible to obtain the optical disc 20 which makes it easy to search for a target program and can realize a function of reproducing in units of groups.

In FIG. 8, an analog or digital interface (IEEE1394 or the like) is used as a data input form.
However, other than this, it is also possible to receive and record content from a server on a communication network / broadcasting network via the Internet or the like. For example, electronic music distribution (EMD)

In FIG. 9, the content from the server 34 is received by the protocol receiving section 35 via a network such as the Internet. Since the received data is generally formatted into a form suitable for distribution,
The delivery format decoder 36 decodes the delivery format as required, and then supplies the formatter 37. The formatter 37 converts the received data extracted from the distribution format decoder 36 into a predetermined format. The received data may include at least one of video data, audio data, and still image data.

The data converted into a predetermined format by the formatter 37 is converted into a signal form suitable for recording by the disk writing section 17 and recorded on the optical disk 40 by using the optical head 19. Note that in FIG. 9, data that is not supplied from the server 34 can be supplied via the video encoder 11, the audio encoder 12, and the still image encoder 13.

Next, an embodiment of the reproducing apparatus of the present invention will be described. FIG. 10 shows a block diagram of an embodiment of a reproducing apparatus according to the present invention. In FIG. 10, the host MPU 25 determines whether to reproduce a program or a playlist according to an instruction from the user via the user interface circuit 24, and writes necessary management data from the disk to the management data memory 26.

Next, the host MPU 25 writes the video, audio, or still image formatted data recorded on the optical disc 21 from the optical disc 21 to the optical head 22 and the disc reading section 23 according to the information in the management data memory 26. After being read out via the, and supplied to the format decoder 28 to solve the format, it is decoded by the video decoder 29, the audio decoder 30, or the still picture decoder 31 to obtain a reproduction output signal. If the video data contains audio data, play the audio
This can be done simultaneously via the audio decoder 30.

In the case of still image reproduction, all the still image data in the user-defined program retrieved from the disk reading section 23 is temporarily loaded into the still image memory 27, and the appropriate still image memory 27 is loaded. Still image data can be input to the format decoder 28 at the timing. In particular, UD_PR_mode is' 011
In the case of b '(audio and still image), it is necessary to load all the still image data into the still image memory 27 before reproducing the audio program.

In the reproducing apparatus shown in FIG. 10, the transmitting device 32
Playback video data (moving image data) output from the video decoder 29, and the audio decoder 3
The reproduced audio data output from 0 and the reproduced still image data output from the still image decoder 31 are transmitted by the transmission device 32.
And then converted to the delivery format here,
It is distributed (transmitted) via a network such as the Internet according to a predetermined protocol.

The present invention is not limited to the above embodiments, and the method shown in FIGS. 6 and 7 and the respective devices shown in FIGS. 8, 9 and 10 can be implemented. It is also possible to realize it with a computer program (software). Further, the present invention is a video (moving image). A method of recording and reproducing three types of contents of audio and still images on a recording medium, and a recording / reproducing method that handles a part of the three types of contents, while exhibiting unique effects regarding the recording medium itself.
