Abstract

PROBLEM TO BE SOLVED: To provide an optical disk on which moving picture data can be recorded so that various types of processing can be applied to the connection part of reproduction sections while assuring recovery at the time of edit failure. SOLUTION: A part close to the terminating end of a preceding reproduction section and a part close to the front end of the succeeding reproduction section are duplicated, and the duplicate portions are designated by Temp Cell information. Cell information which specifies the preceding reproduction section contains a Temp Cell FLAG. When this flag is set to ON '1', the flag shows the reproduction of the portion before the part close to the terminating end of the preceding section and the portion after the part close to the front end of the succeeding section via the duplicate portion designated by Temp Cell information. When this flag is set to OFF '0', the flag shows the reproduction of the preceding section and the succeeding section without any change.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a DVD-RAM, DVD-R,
The present invention relates to a recording / reproducing apparatus for recording / reproducing an optical disc such as a DVD-RW and a DVD + RW, and more particularly to an improvement in editing moving picture data recorded on an optical disc.

[0002]

2. Description of the Related Art In moving image editing, the risk of losing the original moving image due to editing mistakes and the like is constantly increasing. When realizing video editing with consumer devices used by the general public, as well as professional devices used by video production professionals, such loss must be avoided. In recent years, DVD recording devices that have appeared on the market have a function of temporary editing in addition to main editing, in view of such demands. Temporary editing is an editing operation in which pointer information specifying picture data to be a start point and an end point of a playback section is defined according to a user's operation. Differently, the feature is that there is no processing for the original moving image. Since there is no processing for the original moving image, if the editing fails, the editing operation can be repeated as many times as possible, and even a beginner of video editing can work on video editing with peace of mind.

[0003]

By the way, provisional editing can be used for moving image editing with a sense of security, but cannot guarantee that video display will not be interrupted when switching playback sections. This is because the two playback sections are arranged apart from each other on the disc, and it is necessary to randomly access the two playback sections.

[0004] Moving image data recorded on a DVD is MPEG-based based on inter-frame correlation with preceding and following picture data.
It contains a large amount of picture data that has been compression-encoded according to the standard, and it is assumed that these will be sequentially reproduced from the beginning at the time of decoding. When the pointer information is defined in plurality by the temporary editing and two or more playback sections are designated, the picture data located at the end of the preceding one of the two playback sections and the picture data located at the beginning of the subsequent one are included. Are initially encoded with other picture data and are assumed to be sequentially reproduced, and it is difficult to continuously reproduce the reproduction sections, and the above-described preceding reproduction section and subsequent reproduction section are connected. Then, many breaks in the moving image appear.

On the other hand, in moving images of movies and TV broadcasts in which the general public has a lot of opportunities to come into contact, various schemes for visual effects are applied to link the reproduction sections, and reproduction as a result of temporary editing is performed. The section is far from the perfection of the edited product produced by the professional, and makes the user feel unsatisfactory. The object of the present invention is to guarantee recovery in case of editing failure,
An object of the present invention is to provide an optical disk capable of recording moving image data so that various processing can be performed in connection of reproduction sections.

[0006]

The object of the present invention is to provide moving picture data, at least two pieces of playing section information for specifying at least two playing sections in the moving picture data, and a portion near the end of the preceding playing section in the moving picture data. And a duplicated portion obtained by duplicating the vicinity of the front end of the subsequent playback section, and a flag are recorded. The duplicated portion is a portion to be processed, and the flag is Is set to ON, indicating that a portion of the preceding playback section before the end vicinity and a portion of the subsequent playback section after the leading end are played back via the duplicated portion, and set to OFF. This is achieved by an optical disk indicating that the preceding reproduction section and the subsequent reproduction section are sequentially reproduced without passing through the duplication portion.

[0007]

Next, the PGCI table will be described. PG
The CI table includes a plurality of pieces of Playlist information. Playlist information
(Abbreviated as "PLI" in FIG. 3) is an array of CELL information, and is a playback list that instructs the playback apparatus to sequentially play back playback sections. CELL information (abbreviated as “CELLI” in FIG. 3) is pointer information indicating a playback section set based on a temporary editing operation by the user. In the temporary editing, the start point (In point) of the playback section and the end point (Out
The operation for specifying the point is performed. CELL information includes "VOBI_SRP" indicating the target VOB, "Cell_Start_PTM" which is a time code designating picture data to be an In point in the picture data included in the VOB, and Out of the VOB included in the VOB. Includes a time code “Cell_End_PTM” that specifies picture data to be a point. This time code has a time accuracy of a video frame which is a display period of the picture data, and the CELL information is expressed by the time accuracy of the video frame.

The order of CELL information in Playlist information is as follows.
It means the order of the playback section. In other words, in the playlist information, CE
If the CELL information is stored in the order of LL information # 1, # 2, # 3, the corresponding playback sections # 1, # 2, # 3 are "# 1", "#
2 "and"# 3 ". FIG.
FIG. 4 is a diagram schematically showing how a playback section is specified by CELL information #x and # x + 1. As shown in FIG.
The playback section is defined by a three-layer structure of VOB-VOB information-CELL information. The user is the CE in this figure
For the LL information #x, set the In point and Out point of the playback section #x, and for the CELL information # x + 1, set the In point and Ou of the playback section # x + 1.
It is assumed that the t point has been set. CELL information #x specifies this playback section #x. VO in this CELL information #x

Cell_End_PTM at x + 1 indicates the Out point of playback section # x + 1, as indicated by arrow vy6. Playlist information is
With such an array of CELL information, the CELL information is treated as one edited product.

The picture data specified by the CELL information contains a large amount of picture data that has been compression-coded according to the MPEG standard based on the inter-frame correlation with the preceding and following picture data. This compression encoding is performed on the assumption that all the picture data constituting the VOB (VOBU) are sequentially reproduced from the head at the time of decoding. On the other hand, as shown in FIG. 5, the continuous reproduction of the picture data located at the end of the preceding one and the picture data located at the head of the succeeding one of the two or more designated playback sections is the same as the above-mentioned initial period. This is contrary to expectations. Therefore, continuous reproduction of a plurality of reproduction sections specified by the play list information becomes difficult, and in the connection of the preceding reproduction section and the subsequent reproduction section, many breaks in a moving image or the like appear. Since the image reproduction is interrupted each time the reproduction section is switched, the edited product defined by the playlist information is, at worst, a patchy edited product.

Some processing is required for the above-mentioned joints in order to eliminate interruptions and to show a highly completed edited product. There are types of processing methods for making the connection of playback sections look smooth, such as seamless connection, fade-out connection, fade-in connection, and cross-fade connection. FIGS. 6A to 6D are diagrams for explaining each of a plurality of types of processing. In the present specification, the portions to be processed are referred to as “near the end of the preceding reproduction section” and “near the front end of the subsequent reproduction section”. 6A to 6D, it is assumed that the vicinity of the end includes four pieces of picture data such as picture data PC1 to PC4, and the vicinity of the leading end includes four pieces of picture data such as picture data PC5 to PC8.

FIG. 6 (a) shows a seamless connection. In this figure, the last picture data PC4 in the vicinity of the end of the preceding reproduction section is reproduced, and then one video frame is added to the beginning of the subsequent reproduction section. First picture data in the neighborhood
This is a connection mode in which the PC 5 is displayed, and is a processing method that eliminates a discontinuity in reproduction visually. FIG. 6B shows a fade-out connection. In this figure, the brightness of the picture data belonging to the vicinity of the end is gradually reduced in the order of the picture data PC1 to PC3, and the picture data PC4 is displayed with the lowest brightness. This is a connection mode of displaying.

FIG. 6C is a diagram showing a fade-in connection. In this figure, picture data PC4 near the end is shown.
Is reproduced, the picture data PC5 in the vicinity of the front end is displayed with the lowest brightness, and then the picture data PC6 to PC8 are displayed in increasing order of brightness. FIG. 6D shows a cross-fade connection. The picture data PC1 to PC4 belonging to the vicinity of the end are displayed while gradually decreasing the brightness similarly to FIG. 6B. On the other hand, picture data PC5 to PC8 belonging to the vicinity of the front end are shown in FIG.
Display while gradually increasing the brightness as in the case of. Picture data PC1, picture data PC5, picture data PC2
And composite data such as picture data PC6, picture data PC3 and picture data PC7, picture data PC4 and picture data PC8, and subsequent playback when picture data PC4 should be displayed with the lowest brightness The picture data PC8 of the section is made to appear. The above is the processing method for making the connection between the two playback sections look smooth.

Naturally, the processing referred to in the present specification is not only processing for realizing the visual effect of making the connection of the reproduction sections look smooth, but also for compositing computer graphics and animation, and telop. Etc.
All processes involving data operations on VOBs are included in the category. How to set the vicinity of the end and the vicinity of the tip will be described.

FIGS. 7A and 7B are diagrams showing how to set the vicinity of the end and the vicinity of the tip when the processing method is a seamless connection. In FIG. 7A, the VO including the Out point of the preceding reproduction section in the preceding VOB # x
BU # (Out) to the next VOBU from the BUBU are set as the near-end part.
The VOBU including the point is defined as the vicinity of the tip.

The reason for re-encoding up to the next VOBU is to maintain synchronized playback with audio data. Since the picture data is compressed and coded based on the correlation with other picture data, the picture data is not reproduced immediately after being read from the DVD, but is waited for the subsequent picture data to be reproduced. In most cases, this must be done. Therefore, the picture data is stored in the buffer in the playback device from the time it is read from the DVD until it is played back, and the storage period in this buffer is a maximum.
Can be one second. On the other hand, the audio data is stored in the buffer in the playback device for a short period of time, if at all, or very short, so the picture data in the GOP and the audio data read from the DVD one second after the reading of the GOP itself Synchronous playback may occur.

Since the audio data read from the DVD after one second from the reading of the picture data is often one or two VOBUs ahead of the picture data, the picture data included in a certain VOBU is , That VOBU
Has a dependency with the VOBU one or two VOBUs subsequent to the VOBU.
Because of such a dependency, re-encoding is performed up to two VOBUs ahead.

The grounds for determining the vicinity of the terminal end and the vicinity of the tip in this manner are based on the prior art US Pat.
Since it is described in Japanese Patent Publication No. 8,140, refer to this publication for details. Also, in the case of seamless connection, the continuous length of the preceding playback section needs to be longer than a predetermined length. This is because if the continuous length of the preceding playback section is short, sufficient data is not accumulated in the buffer due to the playback of the preceding playback section, so that the buffer underflow occurs during a disk seek caused by random access from the preceding playback section to the subsequent playback section. Is caused.

On the other hand, in processing of types such as fade-out connection, fade-in connection, and cross-fade connection, FIG.
As shown in FIG. 7A, in addition to the VOBU shown in FIG.
The VOBU j points before the VOBU including the Out point is near the end, and the VOBU k times after the VOBU including the In point is near the front end. The numbers j and k are in a range where a visual effect such as a fade-in connection, a fade-out connection, and a cross-fade connection is exerted, and also depends on the user's sensibility as to how to apply the visual effect. In other words, it can be said that the number is fluid. It is customary that the near-end portion and the near-end portion are different from each other.
U # (Out) only, VOBU # (In) including the In point near the tip
Only. The above is the outline of the processing for VOB. It should be noted here that the provisional editing is based on the principle that no processing is performed on the original VOB, so that these processing techniques cannot be directly applied.

Therefore, in the present embodiment, a portion near the end of the preceding playback section and a portion near the front end of the subsequent playback section in the VOB are copied, and the copied portion is written on a DVD for processing. FIG. 8 is a diagram showing a duplicate portion written for data processing. In the figure, duplication is performed as indicated by arrows Cy1 and Cy2. VOB # z in this figure
Is the VOBU # (Ou including the Out point near the end of the preceding playback section
t) to the next two VOBUs), VOB # z
+1 indicates a portion near the leading end of the subsequent playback section (VOBU # (I

It can be seen that VOB information #z and # z + 1 are written as shown in FIG. 4 and Temp_Cell information #z and Temp_Cell information # z + 1 are written as shown by arrows by3 and by4. From this, the duplicate part is VOB-V
A playback section is defined by a three-layer structure of OB information and CELL information. These VOBs #z and # z + 1 are different from other VOBs in that they are specified by a special type of cell information called “Temp_Cell information”. Temp_Cel
l information is a CELL that specifies a playback section to be linked and played between a preceding playback section specified by certain preceding CELL information in the Playlist information and a subsequent playback section specified by the following CELL information. Information. Temp_Cel
lBecause the VOBs #z and # z + 1 specified by the information #z and # z + 1 are duplicated portions that can be respectively processed, the VOBs #z and # z + 1 must be specified in the Temp_Cell information. In the preceding playback section #x
After the end of the reproduction of the reproduction section and before the start of the reproduction of the subsequent reproduction section # x + 1, a copy portion that can be processed can be reproduced.

Next, the data structure of the Temp_Cell information and the Tem
The data structure of CELL information when p_Cell information is set will be described with reference to FIG. FIG. 10 shows the first
FIG. 11 is a diagram illustrating a data structure of CELL information of playlist information according to the embodiment, and FIG. 11 schematically illustrates how a VOB is specified in the CELL information and Temp_Cell information illustrated in FIG. FIG. Differences between the internal configuration of the playlist information in FIG. 10 and the playlist information shown in FIG. 3 are shown in bold frames wk1, wk2, and wk3. In FIG. 10, in addition to the CELL information # 1 to #N shown in FIG. 3, the playlist information includes Temp_Cell information # 1 to #M (Tem
p_CellI). As shown in the bold frame wk3, the Temp_Cell information is “VOBI_SRP” indicating the corresponding VOB.
"Cell_Start_" indicating the start point of the playback section in the VOB

FIG. 11 shows how M and Cell_End_PTM are set.
Arrow cy1, cy2, cy3, cy4. Temp_Cell information #z
Cell_Start_PTM designates the first picture data of VOB # z as indicated by an arrow cy1 in FIG.
l_End_PTM specifies the same picture data as the Out point specified by the user, as indicated by arrow cy2. Temp_
Cell_End_PTM in Cell information # z + 1 specifies the last picture data of VOB # z + 1 as indicated by arrow cy3, and Cell_Start_PTM is the same as the In point specified by the user as indicated by arrow cy4 VOB # z + 1
Is specified for Since VOB #z and # z + 1 are originally a duplicated part near the end of the preceding reproduction section and a duplicated part near the front end of the subsequent reproduction section, Cell_End_ of Temp_Cell information #z
The PTM specifies the same picture data as the Cell_End_PTM of the CELL information #x, and the Cell_Start_PTM of the Temp_Cell information # z + 1 specifies the same picture data as the picture data specified by the Cell_Start_PTM of the CELL information # x + 1. It is.

Next, the data structure of the CELL information in FIG. 10 will be described. In the CELL information in FIG. 10, "VOBI

This is the difference from the CELL information shown in.

"Temp_Cell_SRP" is pointer information indicating the destination Temp_Cell information when passing through the Temp_Cell information. By this Temp_Cell_SRP, CEL in FIG.
The link sy1 from the L information #x to the Temp_Cell information #z is explicitly specified. Temp_Ce via via to Temp_Cell information
It is Temp_Cel that stipulates the link relationship by ll_SRP.
l Duplicate part specified by information (VOB # z and VOB # z + 1)
However, it is based on the possibility of being integrated into one VOB by processing, or being divided into three or more. For example, if VOB # z + 1 is integrated with VOB # z, Temp_Cell information #z
New VOB # in Cell_Start_PTM and Cell_End_PTM
What is necessary is just to update to cover the whole of z, and delete Temp_Cell_SRP contained in Temp_Cell information # z + 1.

When VOB # z + 1 is divided into VOB # z + 1 and VOB # z + 2, Temp_Cell information # z + 1 is replaced with Temp_Cell information # z + 1, # z + 2.
Divided into Temp_Cell information for playback section in VOB # z + 1
Specify at # z + 1 and set the playback section at VOB # z + 2 to Temp_Cell
Information # z + 2, these Temp_Cell information # z + 1, # z + 2
The link between them may be defined by Temp_Cell_SRP. Integration /
Since the VOB of the duplicate part that may be divided is specified in the Temp_Cell information that defines the link relationship, if the duplicate part is integrated or divided, only the Temp_Cell information needs to be updated and the CELL information can be updated. No need to update. Therefore, the trouble of updating at the time of processing can be minimized.

"Trimming_Start_PTM" is a time code indicating picture data located immediately after the front end vicinity. “Trimming_End_PTM” is a time code indicating picture data located immediately before the end vicinity. Trimming
_Start_PTM and Trimming_End_PTM are provided for Temp
This is to prevent the same content from being reproduced twice when passing through the _Cell information. That is, Cell_E of CELL information #x
nd_PTM sets the Out point near the end
Cell_Start_PTM of information # x + 1 is
Since the In point is specified, the Out specified by the user
Points and In points are doubly specified by CELL information and Temp_Cell information. In this case, from the beginning near the end to the Out point,
In addition, the portion from the In point to the end of the vicinity of the front end is reproduced twice. So Trimming_End_PTM and Trimming_Start
The _PTM specifies the picture data located immediately after the front end portion and the picture data located immediately before the end end portion. In FIG. 11, Cell of CELL information #x
_End_PTM specifies the range of the broken line bs1. Meanwhile CELL
Trimming_End_PTM of information #x specifies the last picture data of VOBU # (PreEdge) located immediately before the end vicinity as shown by arrow gy1. Cell_S of CELL information # x + 1
tart_PTM specifies the range of the dashed line bs2. Meanwhile CELL
Trimming_Start_PTM of information # x + 1 designates the first picture data of VOBU # (PostEdge) located immediately after the vicinity of the front end as indicated by arrow gy2. Due to the designation immediately before / after, even when the reproduction is performed via the Temp_Cell information, the duplicate reproduction can be avoided.

As described above, in the data structure of FIG.
When not passing Temp_Cell information, Cell_End_PT
Based on M, Cell_Start_PTM, the entire preceding reproduction section and subsequent reproduction section are reproduced so as to include the vicinity of the end indicated by broken lines bs1 and b2 and the vicinity of the front end. Triming_End_PTM, Trimming_Start when passing through Temp_Cell information
Based on _PTM, it indicates that reproduction is to be performed from the vicinity of the leading end of the subsequent reproduction section up to immediately before the end vicinity of the preceding reproduction section.

“Effect_Type” indicates what kind of visual effect processing has been performed on the VOB specified by the Temp_Cell information. The types of visual effects here include the seam lace connection, the fade-in connection, the fade-out connection, and the cross-fade connection described above. "Temp_Cell_FLAG" indicates that, by being set to "0 (off)", a transition is made directly to succeeding CELL information without going through Temp_Cell information,
By being set to “1 (ON)”, it indicates that the process proceeds to the subsequent CELL information via the Temp_Cell information. Te
As a specific case where mp_Cell_FLAG is set to `` 0 '', if there is not enough space on the DVD to write the duplicated part (1), the duplicated part can be written and processing such as re-encoding Going, but the result is not good and you do not want to regenerate (2). Conversely T
As a specific case in which emp_Cell_FLAG is set to “1”, there is a case where the processing on the duplicated part is successful and the user wants to go to Temp_Cell information specifying the duplicated part on which the processing has been performed.

The presence of Temp_Cell_FLAG allows Te

Second, the right end of the rail gu1 is considered to be 01: 30: 00.00 seconds, and the position of the slide bar gu2 on the rail gu1 is expressed in hours, minutes, and seconds.
Here, assuming that the slide bar gu2 exists at an intermediate position of the rail gu1, 00: 45: 00.00 seconds is the Play point.

Thereafter, the picture data specified by the time code is displayed in the reproduction window gu3. As a result, an arbitrary Play point in the playback section is specified by the operation of moving the slide bar gu2. Then step S
The process proceeds to a loop process consisting of steps 1 to S4. If the desired Play point is not specified by the moving operation on the slide bar gu2, the user specifies the slide bar gu2 again in step S1, and performs the moving operation again in steps S5 to S6, thereby setting the Play point. Fine-tune the position.

It is assumed that the Play point desired by the operator has been designated through the fine adjustment, and the IN button gu4 has been pressed. In this case, in step S8, the Play point is designated as the In point, and in step S9, a mark is displayed at the position designated as the In point on the rail gu1. Step S10
Then, the time code indicating the In point is displayed in the format of hour: minute: second, and in step S11, the thumbnail of the picture data at the In point is displayed in the In point thumbnail gu7. Through the above process, the In point is set. After the In point is set, the slide bar gu2 is specified, the operation to move this slide bar gu2 is performed again, and if the OUT setting button is specified, the Out point is set through the same procedure as the In point Is done.

When the In point and the Out point are set through the above steps, the playback section is determined. Thereafter, the processing shifts to the loop processing of steps S1 to S4, and it is assumed that the section specifying button gu6 is designated. If the section identification button gu6 is designated, step S3 becomes Yes and step S3
It moves to 12. In step S12, the target VOB
Is generated in VOBI_SRP, the In point is specified in Cell_Start_PTM, and the Out point is specified in Cell_End_PTM.

The reason for specifying the vicinity of the end and the vicinity of the tip based on the type of the visual effect is that the portion to be processed may be different for each aspect of the visual effect. When applying visual effects such as fade-in connection, fade-out connection, cross-fade connection, rather than automatically setting the processing range,
It is desirable to allow the user to specify a range in which processing is performed by interactive operation. If the vicinity near the end and the vicinity near the tip are specified,
In step S17, it is determined whether or not the size obtained by adding the near-end portion and the near-end portion exceeds a predetermined size of the DVD. This is because the provisional editing according to the present embodiment involves recording of a duplicated portion, so that the DVD is not full when the free area of the DVD is small. As a criterion for determining the predetermined size, for example, a value obtained by subtracting the data size of 5 to 10 VOBUs from the free space of the DVD is desirable. If step S17 is determined to be Yes, the Te of Cell information # 1 to #n is determined in step S18.
mp_Cell_FLAG is set to “0”, and the processing of this flowchart ends.
