Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing method and system suitable for application to, for example, an editing system.

[0002]

2. Description of the Related Art Conventionally, for example, at a broadcasting station, a work for editing a material to be broadcast and recording it on a video tape cassette is performed. For example, a work for editing and recording a plurality of commercial (CM) materials in one video tape cassette to create a so-called single CM tape, for editing and recording the materials used in one program in a video tape cassette for broadcasting Editing work (for sending) corresponds to this.

Usually, a video tape cassette containing the original material is called a material tape or the like. Play this video tape cassette as a material tape on the VTR,
Various signal processing is performed on the reproduced signal, and the material signal obtained by performing this signal processing is recorded in a video tape cassette used for broadcasting to create a video tape cassette for broadcasting.

FIG. 16 is a block diagram showing an example of a conventional editing system. The conventional editing system will be described below with reference to FIG.

In FIG. 16, 1 is a video tape cassette as a material tape, and 13 is a video tape cassette for broadcasting. The video tape cassette 1 as a material tape is set in the reproduction side VTR 2, and the broadcast video tape cassette 13 is set in the recording side VTR. When the reproducing VTR 2 is in the reproducing state, the video signal is reproduced from the video tape cassette 1 and supplied to the DME (digital multi-effector) 7 for processing.
The processed video signal is recorded in the video tape cassette 13 set in the recording side VTR 8. In this example, an example using the DME 7 is shown, but if a tape for broadcasting is simply created, a system using an editor may be used, and the video and audio output terminals of the playback side VTR 2 may be used. It is also possible to connect the video and audio output terminals of the recording side VTR 8.

That is, in the editing system shown in FIG. 16, the video tape cassette 1 as a material tape is reproduced by the reproducing VTR 2, and the DME 7 performs special effect processing on the reproduced signal output at the normal transfer speed. Then, the reproduction signal subjected to the special effect processing is supplied to the recording-side VTR 8 at a normal transfer rate and recorded in the broadcast video tape cassette 13 set in the recording-side VTR 8.

In the reproducing-side VTR 2 shown in FIG. 16, the reproducing head 3 is connected to one fixed contact 5a of the switch 5 for head switching, and the reproducing head 4 is the other fixed contact 5b of the switch 5 for head switching. Connected to V
The movable contact 5c of the switch 5 is selectively connected to one or the other fixed contact 5a or 5b by a switching signal from a system controller (not shown) of the TR main body 6.

The reproducing VTR 2 is an analog VTR,
Or, even if it is a digital VTR, the playback side VT
The video and audio signals output from R2 are supplied to the DME 7 at a transfer rate based on 60 fields / sec in the NTSC system and 50 fields / sec in the PAL system. To explain using an analog VTR, the video signal output from the playback VTR 2 is NTSC.
The transfer rate is 60 fields / second in the method and 50 fields / second in the PAL method. In this example, DME7
Is an analog video and audio input terminal as an input terminal,
It is assumed to have digital video and audio input terminals.

Then, in the DME 7, the playback side VT
Various processes such as a special effect such as a mosaic effect, image movement, reduction, enlargement, and rotation are performed on the video signal from R2. This processing is, for example, 60 if the NTSC method
Field / second, and in the PAL system, 50 field / second is used as a reference. The output of this DME7 is the recording side V
The VTR body 1 of the recording side VTR 8 supplied to the TR 8
In 2, the analog or digital signal processing for predetermined recording is performed and then recorded in the set video tape cassette 13.

In the recording side VTR 8 as well, as in the reproducing side VTR 2, the recording head 9 is connected to one fixed contact 11a of the head switching switch 11, and the recording head 10 is fixed to the other fixed contact 11b of the head switching switch 11. It is connected to the. The movable contact 11c of the switch 11 is selectively connected to one or the other fixed contact 11a or 11b by a switching signal supplied from a system controller (not shown) of the VTR main body 12. This recording also has the same timing as above, that is, NT
60 fields / sec for SC system, 50 for PAL system
It is done on a field / second basis.

By the way, in the system as shown in FIG. 16, so-called A / B roll editing, that is, two images (A roll and B roll) obtained by reproducing with two reproducing machines are mixed and wiped. In the case of performing editing such that the two screens are combined to freely switch back and forth, another VTR 2 on the reproducing side must be connected to the DME 7 in addition to the VTR 2 on the reproducing side. That is, the playback VTR 2 and the added playback VT
The video and audio data as the A roll and the video and audio data as the B roll reproduced by R are processed by the DME 7, and the processed video and audio data are recorded in the video tape cassette set in the recording side VTR 8. To do so.

The applicant has previously displayed the first and second points of the image data of a predetermined unit on the display means, and the first and second points of the predetermined unit displayed on the display means. By designating the image data by the designating means and displaying the time code data of the image data of the first or second point designated by the designating means, the state of the related equipment, and the identification number by the control means, the editing efficiency is improved. Editing device that can improve the usability as well as
For example, it is possible to change the contents of the edit files EDL1 to EDLn by deleting, copying, moving, and exchanging the position of the image data in edit units displayed on the screen using a pointing device or a keyboard. You can perform editing work without performing any troublesome work such as playing and rechecking, checking the memory address etc. with the keyboard etc. and entering it, thereby improving the efficiency of editing work. We propose an editing device that can be done (Japanese Patent Application No. 5-874).
(See No. 13).

[0013]

As is apparent from the above, when performing A / B roll editing in the conventional editing system, a VTR for A roll reproduction and a VTR for B roll reproduction are provided.
Then, two VTRs for reproduction must be prepared.

In addition, in the editing system using the VTR shown in FIG. 16, another reproducing side VTR is prepared in addition to the reproducing side VTR2, the reproducing side VTR2 is used for A roll reproduction, and the newly arranged reproducing side VTR is used. When performing the A / B roll for the B roll, when it becomes necessary to redo the processing performed by the DME 7, the playback side VTR 2 is operated again and the playback side VT is operated.
Set the position of the magnetic tape of the video tape cassette set in R2 to the beginning of the material as the A roll,
The other VTR on the reproducing side is operated to set the position of the magnetic tape of the video tape cassette set on the VTR on the reproducing side to the beginning of the material as the B roll, and then the processing by the DME 7 is not performed again. Will not happen.

That is, in the case where the editing system using the VTR is used for reworking or rehearsal (practice before the main editing, etc.), the operation for setting the magnetic tape to the head position of the material, and the operation of the VTR for the material used A waiting time for the process to move to the beginning position of is required. Such operation and waiting time are necessary because the device for reproducing and recording is the VTR. Therefore, it is very difficult to improve the editing work efficiency in the editing system using the VTR, and an editing system capable of improving the editing work efficiency has been desired.

Further, in the editing system using the digital VTR, since the amount of data is much larger than that of the analog VTR, it is particularly difficult to improve the editing efficiency, and it has been desired to improve the efficiency.

Further, during the editing work, it is necessary to always pay attention to the recordable time of the video tape cassette set in the recording side VTR 8,
When the recordable time of the video tape cassette becomes "0", the operator must prepare a new video tape cassette and set the prepared new video tape cassette in the recording side VTR8. .

Further, in the editing system as shown in FIG. 16, the VTR on the reproducing side and the VTR on the recording side are uniquely determined. That is, the reproducing VTR 2 shown in FIG. 16 is a reproducing VTR, and the recording VTR 8 is a recording VTR. And DME
7 input terminal is connected, and the input terminal of the playback side VTR2 and D
It is necessary to connect the output terminal of ME7. Of course, it is a condition that the reproducing side VTR 2 can record and the recording side VTR 8 can reproduce.

That is, in the editing system as shown in FIG. 16, once the devices are connected, the input / output paths of the video and audio data to be edited are uniquely determined, and the input / output in the system or There was a drawback that the usage of the device could not be changed easily.

Further, when the editing system as shown in FIG. 16 is remodeled to compensate for the various drawbacks described above, it is difficult to achieve compatibility with existing equipment.

The present invention has been made in consideration of the above points, and the editing of A / B rolls and the like can be performed easily and at high speed, and it is not necessary to worry about the recordable time of the recording medium. Good editing work can be performed even with a VTR, and various input / output paths of video and audio data in the system can be easily changed to make various edits, and compatibility with existing equipment is ensured. An attempt is made to propose a possible editing method and its system.

It is sequentially supplied to the disk array controller 115 via 42 and b43. At this time, the movable contact 131c of the switch 131 is connected to one fixed contact 131a by the switching signal from the system controller 33. When the movable contact 131c of the switch 131 is connected to one fixed contact 131a, the video and audio data sequentially supplied to the disk array controller 115 is supplied to the sixth cache 137 via this switch 131. The video and audio data supplied to the sixth cache 137 is stored in the sixth cache 137.

The video and audio data stored in the sixth cache 137 is supplied to the recorder 24 after being read from the sixth cache 137. The recording machine 24 is brought into a recording state by a control signal from the system controller 33. Then, the video and audio data read from the sixth cache 137 of the data controller 20 by this is recorded on the video tape cassette set in the recorder 24 so as to form an inclined track.

In the above description of the operation, the video and audio data P1 as the A roll and the video and audio data P2 as the B roll are once supplied to an external video and audio processing device and the like. After performing various kinds of processing with the processing equipment, the disk drives 22, 23, 30, and 3 are again used.

It is recorded in the area Ar3 of 23a, 30a, 31a, 34a, 35a, 42a or 43a.

By the way, under the above conditions, for example, the video and audio data P1 is recorded on the disks 22a, 23a, 30.
The area Ar1 of a, 31a, 34a, 35a, 42a, or 43a is read out sequentially during the reproduction time S1.
It is stored in the cache 124, and the first cache 1

The video and audio data P1 read from the first cache 124 by accessing at the reproduction time S1 and the reproduction time S2, respectively.
Must be able to output without interruption.

That is, the disks 22a, 23a, 30
a and 31a, 34a, 35a, 42a, and 43a, the video and audio data P1, which is read from the area Ar1 and output via the first cache 124, the disks 22a, 2

Read from the area Ar2 of 3a, the second cache 12
6, video and audio data P2 output via 6 and video and audio data Ri output via the fourth cache 132
In order to make n each a continuous data string, it is necessary to satisfy the following conditions.

This is because the disks 22a, 23a, 30a, 31a, 34a and 35 are read / write time Tr / w.
a, 42a, and 43a are read from the areas Ar1 and Ar2, and the first cache 124 and the second cache 12 are read.
The data amount of the video and audio data P1 stored in 6 covers the period until the next read / write time Tr / w, and the data amount of the video and audio data Rin stored in the fourth cache 132 is as follows. This is to cover the period up to the read / write time Tr / w.

That is, considering the video and audio data P1, the storage data amount CA1 of the first cache 124> the reproduction data amount in the period TS1 = (read / write time T
r / w) × total transfer speed DDspeed> {3
× (seek time Tseek + read / write time Tr /
w)} × VTR data transfer speed PDspeed.

When the above conditions are actually set and calculated, the read / write time Tr / w = 1.06 × (seek time Tseek).

Here, the seek times Tseek are the same, and the disk drives 22, 23, 30, 31, 3 are the same.
Each disk 22a, 23 according to 4, 35, 42 and 43
a, 30a, 31a, 34a, 35a, 42a and 43
The read / write time Tr / w for a is also equal.

For example, the seek time Tseek is set to 40 mse
When set to c, the read / write time Tr / w is 4
It will be 2.4 msec. In this case, each cache capacity is 0.0424 × (20 MByte / sec) = 0.85.
More than MByte. In other words, seek time 40mse
The amount of data that can be read or written during c is 1.
If the storage capacity is 06 times larger, the reading of the next data can be covered. Also, under this condition, it means that channel chC, channel chD and channel chE are used.

In the above example, the first cache 12
Although the description has been centered on No. 4, the same applies to the second cache 126 and the fourth cache 132. The video and audio data P2 are read / written at the read / write time Tr / w by the disks 22a, 23a, 30a, 31a, 34a, 35.
read from area Ar2 of a, 42a or 43a,
This second cache 1 is stored in the second cache 126.
When the video and audio data P2 is read from 26,
In order to cover the next read time from the area Ar2, that is, the next read / write time Tr / w, under the above-mentioned conditions, 0.85 MByte or more as in the first cache 124. Becomes

Similarly, the video and audio data Rin is converted into the fourth data.
The fourth cache 132 is stored in the cache 132.
In order to cover the next read time from this area Ar3, that is, the next read / write time Tr / w, when the video and audio data Rin is read from , Which is equal to or larger than 0.85 MByte as the first cache 124.

a, 30a, 31a, 34a, 35a, 42a and 43
The read / write time Tr / w for a is also equal.

For example, the seek time Tseek is set to 40 mse
When set to c, the read / write time Tr / w is 8
It will be 7.39 msec. The cache capacity in this case is 0.0897 × (20 MByte / sec) = 1.7.
9 MBytes or more. In other words, seek time 40ms
If the storage capacity is 2.18 times larger than the amount of data to be read or written during ec, the reading of the next data can be covered. Also, under this condition, channels chA, chB, ... C
This means that 4 channels out of hF are used.

In FIG. 7, three channels are fixed,
Switch the remaining one channel to switches 131, 136 and 142.
The selection is in operation. Therefore, when the switch 142 is turned on, it can also be used as a C roll. That is, the additional reproduction video and audio data P3 is transferred to the disk drives 22, 23, 30, 31, 34, 35, 42 and 4.
It is also possible to read the data from the No. 3, output it via the seventh cache 139, supply it to an external video and audio processing device (not shown), and use it as the C roll video and audio data P3.

In the above example, the first cache 12
4 has been mainly described, but the same applies to the second cache 126, the third cache 128, and the fourth cache 132. The video and audio data P2 is read / written at the read / write time Tr / w by the disks 22a, 23a, 30.
When the video and audio data P2 is read from the area Ar2 of a, 31a, 34a, 35a, 42a, or 43a and stored in the second cache 126, and the video and audio data P2 is read from this second cache 126, the next read from this area Ar2 is performed. Time, that is, the next read / write time Tr /
In order to be able to cover up to w, in the case of the above-mentioned condition, it is 1.7 like the first cache 124.
9 MBytes or more.

Similarly, the video and audio data Rin as the complete editing material are read / written at the read / write time Tr / w by the disks 22a, 23a, 30a, 31a, 34a, 3a and 3a.
When reading out from the area Ar3 of 5a, 42a, or 43a, storing it in the third cache 128, and reading the video and audio data Rin from this third cache 128, the next read time from this area Ar3, that is, In order to cover the read / write time Tr / w, it is 1.79 MBytes or more under the above-mentioned conditions, like the first cache 124.

Similarly, the video and audio data Rin is converted into the fourth data.
The fourth cache 132 is stored in the cache 132.
In order to cover the next read time from this area Ar2, that is, the next read / write time Tr / w, when the video and audio data Rin is read from , As with the first cache 124, the capacity is 1.79 MBytes or more.

It is recorded in the area Ar3 of 3a, 30a, 31a, 34a, 35a, 42a, or 43a, and the fifth cache 13
The video and audio data stored in No. 4 is the disk drive 22, 23, 30, 31, 34, 35, 42 or 43.
Discs 22a, 23a, 30a, 31a, 34a,
It is recorded in the area Ar1, Ar2 or Ar3 of 35a, 42a or 43a.

By the way, under the above conditions, for example, the video and audio data P1 is recorded on the disks 22a, 23a, 30.
The area Ar1 of a, 31a, 34a, 35a, 42a, or 43a is read out sequentially during the reproduction time S1.
It is stored in the cache 124, and the first cache 1

Is stored in the first cache 124, and when the video and audio data P1 is read from the first cache 124,
The video and audio data P1 read from the first cache 124 by accessing at the reproduction time S1 and the reproduction time S2, respectively.
Must be able to output without interruption.

That is, the disks 22a, 23a, 30
a and 31a, 34a, 35a, 42a, and 43a, the video and audio data P1, which is read from the area Ar1 and output via the first cache 124, the disks 22a,

n, the video and audio data Rin output via the fourth cache 132, and the video and audio data Pin output via the fifth cache 134 are set as continuous data strings, respectively, which satisfy the following conditions. There is a need.

This is because the disks 22a, 23a, 30a, 31a, 34a, 35 are read / written during the read / write time Tr / w.
Areas Ar1, Ar2 and Ar of a, 42a and 43a
3, the data amount of the video and audio data P1, P2, and Rin stored in the first cache 124, the second cache 126, and the third cache 128 covers the period until the next read / write time Tr / w. ,
And fourth cache 132 and fifth cache 134
That is, the data amount of the video and audio data Rin and Pin stored in the above section covers the period until the next read / write time Tr / w.

That is, considering the video and audio data P1, the storage data amount CA1 of the first cache 124> the reproduction data amount in the period TS1 = (read / write time T
r / w) × total transfer speed DDspeed> {5
× (seek time Tseek + read / write time Tr /
w)} × VTR data transfer speed PDspeed.

When the above conditions are actually set and calculated, the read / write time Tr / w = 5.92 × (seek time Tseek).

Here, the seek times Tseek are the same, and the disk drives 22, 23, 30, 31, 3 are the same.
Each disk 22a, 23 according to 4, 35, 42 and 43
a, 30a, 31a, 34a, 35a, 42a and 43
The read / write time Tr / w for a is also equal.

For example, the seek time Tseek is set to 40 mse
When set to c, the read / write time Tr / w is 23
It will be 7 msec. In this case, each cache capacity is 0.
237 × (20MByte / sec) = 4.74MBy
te or more. That is, 5.92 is larger than the amount of data that can be read or written during the seek time of 40 msec.
With double the storage capacity, it is possible to cover the reading of the next data. Further, this condition means that 5 channels out of the channels chA, chB, ..., chF are used.

In FIG. 7, three channels are fixed,
Switch the remaining channels to switches 131, 136 and 142.
The selection is in operation. Therefore, it is a condition that the movable contact 131c of the switch 131 is connected to the other fixed contact 131b and the switch 136 is turned on for use.

In the above example, the first cache 12
4 has been mainly described, but the same applies to the second cache 126, the third cache 128, and the fourth cache 132. The video and audio data P2 is read / written at the read / write time Tr / w by the disks 22a, 23a, 30.
When the video and audio data P2 is read from the area Ar2 of a, 31a, 34a, 35a, 42a, or 43a and stored in the second cache 126, and the video and audio data P2 is read from this second cache 126, the next read from this area Ar2 is performed. Time, that is, the next read / write time Tr /
In order to be able to cover up to w, under the above-mentioned conditions, it is 4.7 as in the first cache 124.
4 MByte or more.

Similarly, the video and audio data Rin as the completely edited material are read / written at the read / write time Tr / w at the disks 22a, 23a, 30a, 31a, 34a, 3a, 3a.
When reading out from the area Ar3 of 5a, 42a, or 43a, storing it in the third cache 128, and reading the video and audio data Rin from this third cache 128, the next read time from this area Ar3, that is, In order to be able to cover the read / write time Tr / w, under the above-mentioned conditions, it becomes 4.74 MBytes or more as in the first cache 124.

Similarly, the video and audio data Rin is converted into the fourth data.
The fourth cache 132 is stored in the cache 132.
In order to cover the next read time from this area Ar3, that is, the next read / write time Tr / w, when the video and audio data Rin is read from As with the first cache 124, the capacity is 4.74 MBytes or more.

Similarly, the video and audio data Pin is set to the fifth
The fifth cache 134 is stored in the cache 134.
