Abstract

PROBLEM TO BE SOLVED: To automatically extract the part of the compressed moving image data included in a range that is extremely close to a designated point by changing both start and end positions if the pictures which are designated at the editing start and end candidate positions refer to other pictures which are excluded out of an editing range. SOLUTION: It decided whether or not a picture B is designated as a mark- out picture. The mark-out picture refers to a PCT (picture coding type) like a mark-in picture. If a picture I or P is designated as a mark-out picture, the mark-out picture is decided as the designation-out 26. The information on the decided designation-out 26 is stored in a designation-out position area. A picture B26 which is designated as a mark-out picture has the 11th order of display between its preceding picture 118 and following picture P27. Thus, the mark-out position is changed and discriminated based on the preceding and following group-of-picture information.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of editing compressed video data, and more particularly, to automatically cut out a compressed video data portion in a range as close as possible to an editing start point and an editing end point specified by a user with respect to compressed video data. The present invention relates to an editing method and an editing apparatus that can perform the editing.

[0002]

2. Description of the Related Art A moving image, which is effective as a means for transmitting information, has a much larger amount of information than a still image, and it is difficult to handle it on a computer as it is. However, in recent years, the international standard ISO1117 has been used as a moving image compression technique.
MPEG (Moving Pict)
With the improvement of the compression ratio and the reduction of the price of the secondary storage device by the Ure Experts Group, moving images can be handled by a home computer.

[0003] After the first standard, MPEG1, was announced, a broadcasting compression standard called MPEG2 was established. MPEG1 transfers images transferred at a transfer rate of about 1.5 Mbps at a resolution of about 352 × 240 images at about 30 frames per second (NTSC) or 25 frames per second (PAL).
Play around. On the other hand, MPEG2 is 4.0 to 4.0.
An image of about 720 × 480 is reproduced at a transfer rate of about 8.0 Mbps.

Normally, MPEG data is generated by compressing (encoding) analog video input from a camera or a capture board into an MPEG format. The captured MPEG data can be reproduced by a PC in which an MPEG decoder (software or hardware) is installed.

[0005] When MPEG data is captured, there is a demand not to use the captured data as it is in the same manner as normal AVI data, but to delete a part of the data or to paste an image effectively. However, since MPEG performs differential compression as described below, editing is very difficult unlike ordinary digital video.

The MPEG data multiplexes an MPEG video stream, which is data obtained by compressing video, and an MPEG audio stream, which is data obtained by compressing audio, to form an MPEG system stream. MPEG data is usually called MPEG data.
Although it is a system stream, only an MPEG video stream and an MPEG audio stream can be reproduced as MPEG data by a software decoder or the like.

When editing MPEG data, a video stream is particularly problematic. The video stream has a data hierarchical structure. The highest level of this hierarchy is the video sequence. This is the sequence header and 1
It consists of one or more GOPs (GroupOf Pictures) and a sequence end. Each GOP includes one or more pictures (corresponding to frames).

There are the following three types of pictures. These are an intra-picture compressed picture (hereinafter, I picture), a forward prediction compressed picture (hereinafter, P picture), and a forward / backward prediction compressed picture (hereinafter, B picture). An I picture is an image
It is divided into blocks of 6 × 16 pixels, and discrete cosine transform (hereinafter, DCT) is performed in each block. Thereby, the image information is concentrated on the coefficients of the low frequency components. Furthermore, the value is quantized using the fact that human vision is insensitive to high-frequency components. The information compressed by these two processes is encoded using a Huffman table.

A P picture is subjected to differential compression with reference to a temporally preceding I picture or P picture. First, a picture to be compressed is divided into macroblocks of 16 × 16 pixels. In each block, compression within a block, differential compression, and no compressed data (skip) are selected. If the motion compensation vector is the same as the block before the block to be compressed, the block can skip the compressed data. In the differential compression, a motion compensation vector is determined by performing motion compensation on an image of a compression target block with respect to pixels of the reference picture. Intra-block compression refers to performing the above-described DCT within a block to perform compression.

For a B picture, differential compression is performed with reference to an I picture that is temporally earlier and a P picture that is temporally later. The compression target picture is 16 × 1 like the P picture.
It is divided into blocks of 6 pixels. In this block unit, it is selected whether or not there is compression (intra-block compression, differential compression, compressed data) (skip). The selection method is the same as that for the P picture. As described above, highly efficient compression can be performed by using the inter-picture difference compression.

MPEG data is obtained by multiplexing moving image data and compressed audio data compressed in the above-described method in units called packets.

As described above, since the video data in the MPEG performs differential compression by referring to each other,
Since each picture cannot be separated one by one while being compressed, editing is not easy.

Means for solving this problem is disclosed in JP-A-9.
-247620. According to this, since the MPEG performs differential compression on a GOP basis, a user (editor) sets a mark-in (edit start point) and a mark-out (edit end point) by a GOP (Group Of).
A simple cut (edit) can be performed by designating the image in units of Picture.

[0014]

According to MEPG, G
The OP only needs to include one or more I-pictures, and no particular upper limit is set for the number of pictures. The number of pictures in a GOP is generally 15 (0.5 seconds) in the case of an NTSC signal, but may be 1 GOP for all pictures. In this case, all pictures are the same GO
Since it is included in P, cutting (editing) is impossible. In addition, as the number in one GOP increases, the MPEG data is cut off at a position away from the position designated by the user as mark-in or mark-out.

In order to solve this problem, it is conceivable to perform editing in units of pictures. In this method, editing is performed in units of pictures, so that editing moving image data can be extracted within a minimum necessary range. However, when a B picture is designated as mark-in or mark-out, decoding and re-encoding are always performed, and cutout is performed in a state where reproduction is possible even without a previous or subsequent picture. For this reason, there is a problem that processing time is longer in GOP units than in editing.

An object of the present invention is to provide an editing method and an editing apparatus capable of automatically extracting a compressed moving image data portion as close as possible to an editing start point and an editing end point specified by a user for compressed moving image data. is there.

[0017]

According to the present invention, in order to achieve the above object, in a method and an apparatus for editing moving image data using an editing engine, a picture designated as an editing start candidate position is outside an editing range. If another picture is referred to, the start position is changed to the reference picture. If the picture specified as the editing end candidate position refers to another picture outside the editing range, the picture is changed to the end position including the reference picture. By using this method, it is not necessary to perform decoding and re-encoding processing when editing, so that the processing time for editing can be reduced.

Also, if the MPEG data to be edited is M
If the stream is a PEG system stream, the editing start position and the editing end position of the audio stream data are changed with the change of the editing start position or the editing end position of the video stream. By doing so, it is possible to prevent a cycle with the audio stream from being shifted due to a change in the editing position of the video stream, and to perform appropriate editing processing.

Further, the start position and the end position of the editing are specified based on the editing position specification guide information displayed on the display device. By referring to the editing position specification guide information, it is possible to more appropriately specify the editing.

MPEG generated by encoder 15
The data is stored in the secondary storage device 19 or the main memory 11. When the present invention is applied to the compressed moving image editing system, the block 102 surrounded by a broken line in the system 100 shown in FIG. 1 can be omitted.

The secondary storage device 19 or the main memory 11
Is compressed by the decoder 14 when a user requests data reproduction. The expanded video data is written to the frame memory 12 and displayed on the display 13, and the audio data expanded by the decoder 14 is reproduced by the speaker 101.

Next, the structure and editing example of MPEG data will be described with reference to FIG.

The storage order data sequence 20 indicates the order of pictures in which MPEG data is stored in the secondary storage device 19 or the main memory 11. The display order data sequence 21 indicates the order of pictures in which the data decoded by the decoder 14 is displayed in the frame memory. In MPEG, since there are B pictures compressed by bidirectional predictive coding, as shown in the data string 20, two reference pictures (I or P) necessary for decoding the B pictures are used.
Picture) is stored before the B picture. This is preferable because it is not necessary to use an extra buffer to hold picture data when encoding / decoding a B picture. For this reason, the principle of the present invention is that the storage order data 20
It is easy to understand if the data stored on the medium is rearranged in the display order as shown in FIG. The display order data 21 shows such an arrangement.

In the following, in the description of the present embodiment, the editing method will be described using the display order data 21.

The user (editor) specifies the mark-in 22 and the mark-out 25 in the display order data 21 by using the editing device shown in FIG. Here, the mark-in indicates the picture at the cutout start position. Markout indicates a picture at the cutout end position. When the cut-out range is specified as in the mark-in 22 and the mark-out 25, the cut-out picture is a picture sequence of the MPEG data 23. However, if clipping is performed at this position, B4 and B5 pictures cannot be correctly decoded because they refer to 13 pictures. Also, P
Since 6 pictures are also encoded with reference to 13 pictures, they cannot be decoded correctly.

On the other hand, B16-
In the case of the picture of B26, the P26 picture following the B25 and B26 pictures refers to the P26 picture. For this reason,
Does not decode correctly.

Therefore, in order to correctly decode within the designated mark-in 22 and mark-out 25 ranges, as shown in the MPEG data 28, P6 is an I6 picture that does not refer to the preceding I3 picture,
4 and B5 are B4 and B5 pictures referring to I6,
25, B26 picture is not dependent on P27
5, It is necessary to be I26 picture. As described above, when cutting out a picture in the middle as specified, some pictures must be re-encoded again so that decoding can be performed correctly.

According to the present invention, by performing the processing shown in FIG. 3 and subsequent figures, the positions of the mark-in 22 and the mark-out 25 are automatically corrected and cut out so that re-encoding does not occur. MPEG data is 27. Actually, a picture to be cut out from the stored data sequence 20 is selected and read. When the read picture is used as a file, the read picture is arranged and stored as a data sequence 200 in the storage order.

FIG. 3 is a flowchart for explaining the overall processing of this embodiment.

First, when the process starts, in step 31,
The user designates the mark-in 22 and the mark-out 25, and the information is stored in the mark-in position area 94 and the mark-out position 95 area of the edit data table shown in FIG. Next, in step 32, the input information is checked whether the designated mark-in 22 and mark-out 25 are correct. Next, steps 33 and 34 for determining the positions of the designated in 24 and designated out 26 to be actually cut out are executed.
Further, in step 35, the compressed moving image data is cut out, and the process ends.

Next, steps 32 and 33 will be described in detail with reference to FIGS.

FIG. 4 is a flowchart for explaining the process from obtaining the input file information to checking the input information for designating the mark-in 22 and the mark-out 25.

First, in step 41, the secondary storage device 19
Checks whether the input file specified as the file to be edited stored in can be opened. Here, if it cannot be opened, an error process 47 is performed.

If the input file can be opened, it is confirmed in step 42 that the input file is either an MPEG system stream or an MPEG video stream, and the format of the file is changed to a stream in the edit data memory shown in FIG. It is stored in the name area 91. If the beginning of the input file is a back header, it is a system stream, and if it is a sequence header, it is a video stream. In step 43, the information of the header of each GOP included in all the video sequences in the stream is sequentially stored in the GOP header information storage area 92, and the total number of pictures in the input file is determined by using Time Code (TC). Is counted, and the total number is stored in the total picture number area 93 of the edit data table shown in FIG. In this embodiment, it is assumed that the total number of pictures is 1500.

Next, at step 44, mark-in 2
Check if the value of 2 is greater than 0. This means that when mark-in is designated, the time from the beginning of the video sequence is determined using the TC stored in the GOP header information to which the picture belongs, and the picture number of the GOP is determined by the picture. TR (Tempo) in the header
ral Reference). The value is determined from the information of the picture header. In the present embodiment, since the mark-in 22 is the fourth B4 picture, the result is Yes. The information is the mark-in location area 9
4 (FIG. 9).

In the case of Yes, it is determined whether the value of the mark-out 25 is equal to or less than the total number of pictures in the same manner as in the case of the mark-in 22. In this embodiment, the markout is 26,
Yes because it is less than 1500. Mark out 2
The value of 5 is stored in the mark-out position area 95 (FIG. 9).

If step 45 is Yes, step 4
The process proceeds to step 6 to check whether the value of the mark-in 22 is smaller than that of the mark-out 25 using the values stored in the mark-in position area 94 and the mark-out position area 95 in FIG. Here, since the mark-in 22 is smaller than the mark-out 25, the process proceeds to the next steps 33 and 34.

If an error occurs, the process proceeds to step 47 to wait for a correct input file, mark-in 22, and mark-out 25 to be input. Through the above processing, it is possible to confirm whether the mark-in 22 and the mark-out 25 have been correctly specified.

FIG. 5 and FIG.
2 is a flowchart showing step 33 in detail. Here, a description will be given of a process of changing the positions of the mark-in 22 and the mark-out 25 and determining the designated in 24 and designated out 26 so as to be editable without re-encoding.

In FIG. 5, at step 51, it is determined whether the marked-in picture is an I picture. The picture type is the Picture Coding Type of the picture header stored in the mark-in picture information.
(PCT). In the case of an I picture, the mark-in picture does not refer to the previous picture,
There is no need to change the specified mark-in position. Therefore, the process proceeds to step 55 where the mark-in 22 is designated
4 is assumed. The information of the confirmed designated in 24 is stored in the designated in position area 96 of the editing data table shown in FIG.

If the marked-in picture is a P picture or a B picture, the flow advances to step 52. In step 52, the GOP header information of the edit data table is searched, and the GOP to which the picture designated
, It is determined whether or not the picture designated as mark-in is displayed before the first I picture in the GOP to which the picture belongs. This is GO
P header information 92 and T of picture header information 98
The determination is made with reference to R. Or GO created before and after
The determination is made with reference to the P information.

FIG. 6 shows an example of the GOP information before and after the mark-in operation.

In field 60, G before mark-in
The OP holds the display order picture information 61, 62 and 63 in the OP, the current GOP, and the subsequent GOP. In the case of this embodiment, since there is no GOP before GOP1, the field 61
No information as shown. The field 62 that is the current GOP is one of the flags (CG) in the GOP header.
Indicates that the GOP having the mark-in is a Closed GOP. Here, the closed GOP is G
This flag indicates that the picture in the OP has not been encoded with reference to the picture in the previous GOP.

Also, this indicates that the B4 picture 63 designated as mark-in is fourth in the display order, and is preceded by an I3 picture. Using such preceding and following GOP information, it is determined whether the picture designated as mark-in is located before the I-picture in the GOP including the mark-in picture in display order.

Returning to FIG. 5, the picture designated as the mark-in in step 52 has the GOP to which it belongs in display order.
If it is before the first I-picture of
Is determined by the Closed GOP or the field 62,
In the case of a lost GOP, the process proceeds to step 55, where the mark-in picture is set to the designated in 24.

A GOP having a mark-in picture is Clo
If it is not the second GOP, the process proceeds to step 54, where G
With reference to the header information of the previous GOP in the OP header information area, the last I picture in the previous GOP is designated as the designated IN. Alternatively, the first I picture in the current GOP may be set as the designated IN.

Further, if the picture designated as mark-in in step 52 is later than the first I picture of the GOP to which it belongs in the display order, the process proceeds to step 56, and the picture is referred to by referring to the GOP header information. Let the I-picture immediately before the mark-in in the GOP to which it belongs to be the designated in. In the case of the present embodiment, since the mark-in picture (B4) is located after the I3 picture in GOP1 having the mark-in using the preceding and following GOP information, the process proceeds from step 54 to step 56, and the I3 picture is designated as the designated in 24. .

When the picture to be designated in is determined by the above processing, the process proceeds to designated out determination processing.

FIG. 10 shows a flowchart of the designated out determination process.

First, in step 1001, it is determined whether or not the picture designated for markout is a B picture. This is also the same as for mark-in-picture,
Refer to T. If the picture specified for markout is I
Alternatively, if the picture is a P picture, the flow advances to step 1004 to set the mark-out picture to the designated out 26. The determined information of the designated out 26 is stored in the designated out position area 97 of the edit data table 90 shown in FIG.

If the markout is a B picture, it is determined in step 1002 whether or not the markout 25 is the last picture by referring to the GOP header information 92 (FIG. 9). Alternatively, before and after GOP information created in advance may be used.

GO before and after mark out in this embodiment
FIG. 7 shows an example of the P information. The field 70 holds the display order picture information 71, 72, 74 in the GOP before the mark-out, the current GOP, and the GOP after the GOP. Also, the B26 picture 73 designated for markout
Is the eleventh in the display order, and it can be seen that there is an I18 picture before it and a P27 picture after it. Using such preceding and following GOP information, it is determined whether to change the mark-out position.

Returning to FIG. 10, if it is determined in step 1002 that the mark-out is the last picture in the GOP or all the pictures, the process proceeds to step 1004. If the mark-out picture is the last picture in the GOP or all pictures, the process proceeds to step 1004, and the picture is designated as the designated out 26. If the mark-out picture is not the last picture, step 100
Proceeding to No. 3, the closest I or P picture after the markout 25 is designated as the designated out 26.

In the case of the present embodiment, since the B26 picture is designated as the markout 25, step 10
02, and since it is not the last picture, the process proceeds to step 1003, where the immediately following P27 picture is determined as the designated out 26, and the process ends.

By these processes, the MPEG data string 23 specified by the mark-in 22 and the mark-out 25 is
