The disk array block 62 for video data and the disk array block 63 for audio data are each composed of a disk array device having a plurality of hard disks therein. Video data and audio data are recorded. The disk array blocks 62 and 63 are designed to record data with redundancy when recording data, so that even if one of the hard disks in the disk array device fails, the failed hard disk can be used. The recorded data can be restored (also referred to as a reconstruction operation). Incidentally, a disk array device having such a data reconstructing function is generally equipped with a RAID (Re-
dandantArray of Inexpensive Disks).

Here, such disk array blocks 62 and 63 will be specifically described with reference to the drawings. However, since the disk array blocks 62 and 63 have basically the same configuration, only the disk array block 62 will be described here. As shown in FIG. 9, the disk array block 62 is roughly divided into a buffer memory 62A and a disk array controller 62.

It is made up of

The buffer memory 62A is a memory for temporarily storing data. The buffer memory 62A sequentially receives and stores the SCSI format data S67 transmitted from the system control block 61 shown in FIG. Is temporarily stored with the data transmission.

The disk array controller 62B is a circuit for controlling the entire operation of the disk array block 62, such as the recording operation and the reproducing operation. The disk array controller 62B receives data related to a control command from the system control block 61 among the data stored in the buffer memory 62A via a command data bus 62P, and sends command data corresponding to the control command to the command data bus 62P. Multiplexor 62C, SC
The operation of each unit is controlled by transmitting the data to the SI protocol controllers 62E to 62I and the hard disks 62J to 62N.

At the time of data recording, the data multiplexer 62C reads data to be recorded such as video data from the buffer memory 62A, distributes the data to the hard disks 62J to 62M via the SCSI protocol controllers 62E to 62H, and distributes the distributed data. The content is notified to the parity operation circuit 62D. When reproducing data, the data multiplexer 62C combines the data reproduced from each of the hard disks 62J-62M into one and sends it to the buffer memory 62A, and if there is any data that could not be reproduced due to damage to the hard disks 62J-62M. For example, based on the parity data supplied from the parity operation circuit 62D, the data is reproduced by a reconstruction operation.

At the time of data recording, the parity calculation circuit 62P calculates parity data of the data based on the data contents distributed by the data multiplexer 62C, and transfers the parity data to the hard disk 62N via the SCSI protocol controller 62I. Supply.
When reproducing data, if there is data that cannot be reproduced from the hard disks 62J to 62M during data reproduction, the parity operation circuit 62P sends the parity data reproduced from the hard disk 62N to the data multiplexer 62C.

The SCSI protocol controller 62E ~
62I is a data multiplexer 62C when recording data.
And the parity data supplied from the parity operation circuit 62P is converted into a data format suitable for the recording format of the hard disks 62J to 62N, and the converted data is converted to the hard disk 62.

Incidentally, if the SCSI protocol controllers 62E to 62I detect that the data cannot be reproduced due to a failure of the hard disks 62J to 62N when accessing the hard disks 62J to 62N, the SCSI protocol controllers 62E to 62I transmit the detection result to the disk array. Controller 62

2C can be instructed to reconstruct data.

The hard disks 62J to 62N are data storage means for distributing recording data such as video data and recording the data in parallel. In this example, four hard disks 62J to 62M are provided to distribute data, but the number is not particularly limited. The hard disks 62J to 62M are used for storing the SCSI protocol controllers 62E to 62H during data recording.
Is sequentially recorded in a desired recording area, and at the time of data reproduction, the data is sequentially read and
It is sent to the CSI protocol controllers 62E to 62H. By providing a plurality of hard disks 62J-62M and distributing and recording data, the disk array block 62 can reliably record even large-capacity data such as video data. Can be.

The hard disk 62N is data storage means for recording parity data calculated based on data to be recorded. This hard disk 62N

Is sequentially recorded in a desired recording area, and at the time of data reproduction, the parity data is sequentially read and read by the SCSI protocol controller 62I.
To send to. As described above, the parity data calculated based on the data to be recorded is recorded on a hard disk 62N different from the hard disks 62J to 62M for recording the data to be recorded. Even when the data cannot be reproduced from 62J to 62M, the data can be reconstructed based on the parity data.

Here, the principle of the data reconstruction will be described. First, among the data allocated by the data multiplexer 62C, the data allocated to the hard disk 62J is D0, the data allocated to the hard disk 62K is D1, the data allocated to the hard disk 62L is D2, and the data allocated to the hard disk 62M. Is D3, and the parity data calculated by the parity operation circuit 62P is PD.

In the parity operation circuit 62P, FIG.
A logical operation means 70 as shown in FIG. 1A is provided, and the logical operation means 70 calculates parity data. This logical operation means 70
The data D0 allocated to the hard disk 62J, the data D1 allocated to the hard disk 62K, the data D2 allocated to the hard disk 62L, and the data D3 allocated to the hard disk 62M are added.
If the addition result is an even number, parity data PD with a value "1" is output, and if the addition result is odd, parity data with a value "0" is output. Incidentally, when the addition result is “0”, the parity data PD having the value “1” is output assuming that the addition result is an even number.

Specifically, as shown in FIG.
For example, when the data D0 to D3 are all “0”, the logical operation means 70 adds “0” because the addition result is “0”.
When the data D0 to D2 are the value “0” and the data D3 is the value “1”, the addition result becomes “1”, so the parity data PD having the value “0” is output. Output. Hereinafter, the parity data PD as shown in the table of FIG. 10B is output for other data combinations based on the same principle. The parity data PD calculated in this manner is recorded on the hard disk 62N via the SCSI protocol controller 62I as described above.

Then, the parity data PD reproduced from the hard disk 62N is input, and the logical operation means 71 executes an operation for reconstructing the data D2. The logical operation means 71 receives the input data D0, D1, and D similarly to the logical operation means 70 for calculating the parity data PD.
3 and the parity data PD are added, and if the addition result is an even number, reconstructed data (D2) having a value “1” is output;
If the addition result is an odd number, the reconstructed data (D
Output 2).

More specifically, as shown in FIG.
For example, when the data D0, D1, and D3 have a value of “0” and the parity data PD has a value of “1”, the logical operation means 71 adds “1” to the reconstructed data (“0”). D2), and the data D0, D1, and PD have the value “0”.
When the data D3 has the value "1", the addition result is also "1", so that the reconstructed data (D2) having the value "0" is output. Hereinafter, reconstructed data (D2) as shown in the chart of FIG. 11B is output for other combinations of data based on the same principle. FIG. 11B and FIG.
As can be seen by comparing 0 (B), the data D2 that could not be reproduced due to the failure of the hard disk 62L has been accurately restored.

As described above, in the disk array block 62, at the time of data recording, data D0 to D
3, the parity data PD is calculated on the basis of the parity data PD, and the parity data PD is recorded on the hard disk 62N.
Data D0, D due to 2K, 62L or 62M failure
Even if the data D1, D2, or D3 cannot be reproduced, the data D0, D0,
D1, D2 or D3 can be reliably restored.

(2-8) Setting of In Point and Out Point Next, setting of the in point and the out point for the events arranged on the time line 95 of the program window 94 will be described. The setting of the IN point and the OUT point for the event on the timeline 95 is executed under the control of the CPU 21 in accordance with the setting procedure of the IN point and the OUT point by the video editing application software shown in FIGS.

That is, the procedure for setting the IN point and the OUT point is as follows. First, in step SP21, the source selection button 1 of the view window 100 displayed on the monitor 2B is displayed.
By selecting and clicking one of 02A to 102E, a predetermined source device is selected under the control of the CPU 21 in step SP22. Here, in the next step SP23, it is determined whether or not the source device selected under the control of the CPU 21 is the daily server 6 or the local storage 8, and if the source device is the daily server 6 or the local storage 8, the process proceeds to step SP24. .

At step SP24, when the source selection button 102 corresponding to the selected daily server 6 or local storage 8 is clicked again, the CPU 21
Of the daily server 6 on the editing screen 90
Alternatively, a file list 103A of the material stored in the local storage 8 is displayed. In the following step SP25, one of the file names displayed in the file list 103A is clicked to select an editing material. As a result, the editing material is set.

Next, at step SP26, when the TL button 126 displayed on the view window 92 is clicked on, the device to be controlled by the CPU 21 is moved to the timeline 95 at step SP7. Setting of the IN point and the OUT point for the edited material is started by an input operation on the timeline 95 via the.

At this time, the CPU 2
Under the control of 1, the now line 139 is displayed, and the clip image of the event corresponding to the time code at the display position of the now line 139 is displayed on the screen of the viewer 106.

Here, in step SP23, when the CPU 21 determines that the selected source device is another source device of the daily server 6 or the local storage 8, the process proceeds to step SP28, where the further selected source device is the VTR 7. Whether there is a CP
This is determined by U21. If it is determined that the selected source device is the VTR 7, the process proceeds to step SP6, and executes the processes of steps SP26 and SP27.

Subsequently, at step SP29, a desired position of the file is searched by moving the now line 139 to a desired position on the time line 95 via the slider section 120 of the device control section 96. At this time, the now line 13 on the timeline 95
9 is displayed in red, and the movable range of the now line 139 is also displayed in different colors. Thereby, the moving range and the position of the now line 139 can be easily confirmed.

Here, the program on the timeline 95 is reproduced in the shuttle mode or the like under the control of the device control section 96, thereby obtaining the viewer 1
On 06, an image at the position of the now line 139 can be displayed, and at the same time, a time code can be displayed in the time code display field 106.

Here, when the mark-in button 115 is click-input at a desired position while referring to the clip image and the time code, the control of the CPU 21 proceeds to step SP3.
Moving to 0, the in-point is set at the time code position corresponding to the display position of the now line 139 for the event set on the time line 95. At this time, under the control of the CPU 21, a stamp image (for example, a picture of a flag, etc.) of the in-point of the event is displayed in the in-point image display column 110 on the viewer window 92, and at the same time, an in-point time code display column 111 of the event is displayed. Indicates the time code of the In point.

At step SP31, the program on the timeline 95 is reproduced under the control of the device control section 96, and the viewer 106
While monitoring the image displayed above and the time code displayed in the time code display field 108, the user clicks the mark-out button 116 with the desired time code. As a result, control of the CPU 21 proceeds to step SP32, and an out point is set at a time code position corresponding to the display position of the now line 139 with respect to the event set on the time line 95. At this time, the out-point display column 1 on the viewer window 92 is controlled by the CPU 21.
12 is a stamp image of the out point of the event (for example,
A flag picture) is displayed, and at the same time, the time code of the out point is displayed in the out point time code display field 113.

Next, in step SP33, the CPU 2
The event time between the in point and the out point is calculated from the time code of the in point and the out point set for the event on the timeline 95 under the control of the first control, and the event time is displayed in the DUR display column on the view window 92. Displayed at 114.

Next, in step SP34, for example, a clip CL of an event to be inserted between the in-point and the out-point of the event on the time line 95 is input to the log window 9.
3 and dragging it, and dropping it near the IN point or OUT point of the timeline 95. As a result, an event corresponding to the clip CL to be inserted between the IN point and the OUT point of the time line is pasted under the control of the CPU 21 in step SP35.

Here, in step SP28, when it is determined that the selected source device is another source device of the VTR 7, it is determined that the selected source device is the auxiliary input unit AUX or the internal input INT, and the processing step is performed. Is moved from step SP28 to step SP35, and the image information to be inserted, which is input from the auxiliary input unit AUX or the internal input INT, between the IN point and the OUT point of the time line 95, is pasted at a predetermined position on the time line 95.

[0189] In this manner, by reading from the source device on the view window 92 and setting the in-point and out-point, the pasting of the edited material cut out on the timeline 95 is completed. The procedure for setting the out point ends.

In step SP35, FIG.
In the following four cases as shown in FIG. 8, the clip CL is set between the in point (shown as mark-in in the figure) and the out point (shown as mark-out in the figure) of the event set on the timeline 95. A material (hereinafter, simply referred to as a clip material) can be attached.

That is, as a first case, there are cases where an in point and a mark out are set on the timeline 95, and only a mark in is set for a clip. In this case, the markout of the clip material that has not been set is determined by the CPU 21 based on the timeline and the time codes of the in point and the out point of the clip material.
Is set in accordance with the mark-out set on the timeline 95 by the arithmetic processing of.

Here, if the markout of the clip material is not enough for the markout of the timeline 95, and if there is room in the length of the clip material read out in the view window 92, the markout of the clip material is controlled by the CPU 21. When the markout of the clip material exceeds the markout of the timeline 95, the markout of the clip material is shortened according to the markout of the timeline 95. Is set.

In the second case, the time line 9
5 only mark-in is set and the clip CL
In some cases, mark-in and mark-out are set. In this case, the markout of the timeline 95 is set by the CPU 21 to a value corresponding to the markout of the inserted clip material based on the time codes of the in point and the out point of the timeline and the clip.

In the third case, mark-in and mark-out are set for the clip material, and only the mark-out is set on the timeline 95. In this case, the mark-in of the timeline 95 is set by the CPU 21 in accordance with the mark-in of the inserted clip based on the time code of the mark-in of the clip.

As a fourth case, mark-in and mark-out are set on the timeline 95, and mark-in and mark-out are set for the clip material. In this case, the timeline 95
If the CPU 21 determines that the length between the mark-in and mark-out of the above event matches the length between the mark-in and mark-out of the clip material, the clip material is just entered on the timeline. It is pasted as it is between the point and the out point.

On the other hand, when the CPU 21 determines that the length between the mark-in and mark-out of the event on the timeline 95 does not match the length between the mark-in and mark-out of the clip material. ,
The length of the clip material that does not match is reset by the CPU 21 in accordance with the mark-in or mark-out set on the timeline 95.

Thus, while monitoring the event image displayed on the viewer 106, the timeline 9 is input by a simple input operation via the device control section 96.
5, an in point and an out point can be set for the event read out.

Further, a clip material to be inserted between the IN point and the OUT point of the event set on the time line 95 can be pasted by a simple input operation using a mouse. At this time, the time code of the IN point and the OUT point of the clip material to be pasted on the event on the timeline 95 is matched with the timecode of the IN point and the OUT point set for the event on the timeline 95 by the arithmetic processing of the CPU 21. Can be set and pasted automatically.

(2-9) Pasting of Event on Timeline Here, the clip CL registered in the log window 93 is pasted on an event on the timeline 95, and an effect is added to the event. The case of editing will be described.

In the video effect editing, first, in the log window 93, the quick entry button 180
By clicking (FIG. 16), the registration mode can be set for the clip material corresponding to the clip CL displayed on the log window 93. The log window 9 in which the registration mode is set in this way
In step 3, the clip material of the clip material to be edited is clicked and selected with the mouse 2D in the order in which the clip material is to be edited, so that the clip material of the clip material selected under the control of the CPU 21 becomes the base video line 132A and the base The audio line 132B is sequentially arranged at the position of the now line 139.

In this case, when one event is placed at the position of the now line 139 of the time line 131, the now line 139 moves to the position of the out point of the event. Then, the clip C that you want to line up with the mouse 2D
When L is clicked, the clip material corresponding to the clip CL is arranged at the moved now line 139. Hereinafter, the now-clip clip material of the clip CL is moved to the now line 139 behind the clip material.
Arranged in position.

When the events are arranged on the time line 95 in this manner, all the lines of the time line 95 can be previewed from the position of the now line 139 by the preview button 123B of the function key. This preview operation is performed by the all-stop button 1
Canceled by clicking 23C. The events on the timeline 95 can be recorded in the local storage 8 by clicking the REC button 123D of the editing picture 90.

As described above, the clip materials displayed in the log window 93 are arranged on the timeline 95 by a simple operation of clicking with the mouse 2D in the order in which the clip materials are arranged. The editing operation for arranging on the line 95 can be greatly simplified, and the editing efficiency can be improved.

(2-10) Effect Setting Using Dialog In the editing apparatus 1, the animation effect or two animation effects in which the effect video is applied to the event video arranged on the base video line 132A on the timeline 95 are used. The transition effect is switched by applying the effect at the turn of the event. Here, when applying the effect to the event pasted on the timeline 95, first, the video effect
By clicking the button 159, an effect setting dialog 190 as shown in FIG. 29 is displayed on the editing screen 90.

When effects are to be applied to the events arranged on the timeline 131, a desired effect pattern is selected in this dialog 190 and pasted on the effect line 135 on the timeline 95. In this case, as a method of selecting an effect pattern, first, the pattern number of a desired effect pattern is input to the pattern number setting unit 191 by the keyboard 2C.
There is a method of selecting by pressing the enter key after inputting more numeric keys. Secondly, about 10 types of bitmaps that graphically represent images of frequently used effect patterns (hereinafter referred to as “favorite patterns”).
There is a method in which the desired effect pattern is displayed on the pattern display section 192 and clicked to select a desired effect pattern from the fiber pattern display section 192. Incidentally, as a favorite pattern, a page turn 19 for switching the background screen to the foreground screen so as to turn the page when switching the screen.

2B or the like is set.

After selecting an effect pattern to be set for an event on the timeline 95 by either the first or second method described above, the transition setting unit 193A on the dialog 190
Enter the transition time (transition time) of the effect and press the enter key, or click the desired transition time from the transition button 193B in which several typical transition times are set. Select and set the time.

After the effect type and the transition time to be set for the event are determined in the dialog 190 in this way, the desired information in the fiber pattern display section 192 of the dialog 190 is determined by, for example, the above-described second method. As shown in FIG. 30A, the pattern bit map 192X of the transition effect is dragged by the mouse 2D, and is moved to the effect line 135 above the event to be switched by applying the effect on the time line 95. Drop. As a result, for example, as shown in FIG. 30B, a transition effect, Mix192X 'can be set for the event of the baseline 132.

When an animation effect is added to an event on the timeline 95, first, the TL button 126 is clicked in the view window 92 to change the control target of the device control section 96 to the timeline 95. Transfer to At the same time, an event (base event) on the baseline 132 at the now line 139 is read out to the view window 92, and
Can be subject to device control. Here, when device control such as playback and jog is performed, the now line 139 moves on the time line 95, and in conjunction with this, a base event on the view window 92 is displayed on the view 106.

Here, at a predetermined position on the timeline 95, the mark-in button 115 and the mark-out button 1
By inputting 16 by clicking, an in point and an out point are set for the event. As a result, FIG.
As shown in FIG.
Bitmaps 166A and 166B corresponding to the IN point and OUT point are displayed at a position on 7 and mark lines 166C and 166D are displayed on the timeline 95. Thus, the baseline 1 of the timeline 95
At 32, the insertion range of the effect event can be set.

Next, a desired clip CL is selected from the clips CL in the log window 93, dragged with the mouse 2D, and dropped close to the mark line 166C at the in-point position set on the timeline 95. Here, in the dialog 190, for example, the animation effect is clicked and selected by the mouse 2D from, for example, the favorite pattern display section 192.
As a result, as shown in FIG. 31B, the animation effect (in this case, the picture-in-picture (Pin) in this case) selected from the fiber pattern display section 192 is positioned at the in-point of the overlay video line 136.
The event EF0 of P)) can be pasted.

(2-11) Registration of pattern bit map When registering a fiber pattern in the fiber pattern display section 192, first, a pattern list button 194 is clicked, so that a bit map of a plurality of effect patterns is obtained. Displays a graphically displayed list (not shown), and reads out a desired effect to be registered in the fiber pattern display unit 192 as a fiber pattern from the list. Alternatively, by inputting a pattern number of a desired effect pattern into the pattern number setting section 191 with ten keys, the bit map of the effect pattern is read out to the bit map display column 195, and the bit map thus read out is used by the mouse 2D. By dragging and dropping at a desired position on the fiber pattern display section 192, it is registered in the fiber pattern display section 192.

Thus, the operator can set the time line 9
5, a desired effect pattern is dragged by the mouse 2D from among a plurality of effect patterns registered in the favorite pattern display section 192 displayed on the same screen as that at the desired position of the event on the timeline 95. The effect can be quickly set for the event by a simple operation of dropping.

(2-12) Setting of Transition Effect Next, a case where a transition effect and an animation effect are actually set for an event set on the timeline 95 will be described.

For example, as shown in FIG. 32A, if there is a now line 139 at the switching position of two events E0 and E1 arranged on the time line 95, C
When the PU 21 determines, the CPU 21 sets each event E0
First, based on the event data of E1 and E1, the event E0 located on the left side of the event E1 on the timeline 95 is set to the background, and then the event E0 is set.
Search for the out point.

Next, the event E1 located on the right side of the event E0 is set to the foreground, and the in point of the event E1 is searched. Thus, when a transition effect is applied to the position of the now line 139 on the timeline 95, the background and foreground for each event can be automatically set, and the switching position of the events E0 and E1 can be read. Therefore, the state of the transition effect at the switching position can be immediately confirmed on the viewer 106.

As shown in FIG. 32B, when CPU 21 determines that there is a now line 139 between events E1 on time line 95 and there is no target event on overlay line 136, control by CPU 21 After setting the event E1 to the background and searching the position of the now line 139 of the event E1, the now line 139 of the event E1 is set to the foreground. As a result, the now line 139 on the time line 95 is obtained.
When the transition effect is applied to the position E, the background and the foreground for the event E1 can be automatically set, and the event E1 can be set.
By reading the switching position of the switching position, the state of the transition effect at the switching position is displayed in the viewer 106.
You can see it immediately above.

(2-13) Animation Effect Setting As shown in FIG. 32C, the NOW line 139 is located at the start position of the animation effect Cut on the timeline 95, and the effect line is located on the overlay line 136. When the CPU 21 determines that there is an event E2 to be processed, the event E1 is controlled by the CPU 21.
Is set to the background and the out point of the event E1 is searched. Further, under the control of the CPU 21,
The event E2 on the overlay line 136 is set to the foreground, and the in point of the event E2 is searched. As a result, the nowline 13 on the timeline 95
When applying animation effect to position 9,
Background and foreground settings for each event can be made automatically, and the event E1
By reading out the IN point of the event E2 and the IN point of the event E2, the state of the animation effect at the position where the effect is applied can be immediately confirmed on the viewer 106.

As shown in FIG. 32D, the now line 1 is located at a predetermined position in the animation effect Cut.
39, and the CPU 21 determines that there is an event to be effected on the overlay line 136, the event E1 is set to the background under the control of the CPU 21, and the now line 1 of the event E1 is set.
The position of 39 is searched. Next, the event E2 is set to the foreground, and the position of the now line 139 of the event E2 is searched. As a result, the event E1 arranged on the timeline 95 as described above corresponds to the event E1.
When applying an animation effect using 2,
The background and foreground settings for each event can be set automatically, and the NOWLINE 1
By reading the position of 39, the now line 139
View the state of the animation effect at the position 1
06 can be confirmed immediately.

Further, as shown in FIG. 32E, an effect can be applied to a single event, for example, A
When the CPU 21 determines that there is a now line 139 in the middle of a roll effect section (indicated as “Mirror” in the figure), the event E1 is set to the background by the control of the CPU 21 and the now line 139 of the event E1 is set. The position is searched, and the position of the now line 139 of the event E1 is set to the foreground.
Thus, when the animation effect by the A roll effect is applied to the event E1 on the time line 95, the background and the foreground for the event E1 can be automatically set, and the position of the now line 139 is read. By the way,
The state of the animation effect at the now line 139 can be immediately confirmed on the viewer 106.

(2-14) Manual Transition Operation of Effects Here, for example, as shown in FIGS. 32A and 32B, the event E0 and / or the event E1 to which the transition effect is applied Foreground and back ground are set for
The effect pattern is displayed in the dialog 190 (FIG. 29).
By operating the fader lever 196, test reproduction can be performed on the screen of the viewer 106.

In this case, a background is displayed on the viewer 106 when the fader lever 196 is located at the uppermost position. Further, as the fader lever 196 is dragged by the mouse and moved from the top to the bottom, the transition effect pattern displayed on the viewer 106 shifts to the foreground in accordance with the transition effect pattern. I will do it. When the fader lever 196 is located at the lowest position, a foreground is displayed on the viewer 106.

As a result, the event of the transition effect can be reproduced at an arbitrary speed by manual operation of the fader lever 196.

When the AT button (Auto button) 197 is clicked in the transition effect setting state, the feeder lever 19 is first activated.
6 moves to the uppermost position, then gradually moves to the lower position, and transitions at the set transition time. Thus, the transition effect can be automatically reproduced on the viewer 106.

Similarly, as shown in FIGS. 32 (C) to 32 (E), after setting the foreground and background for events E1 and E2, the effect pattern number is set by selecting the effect pattern number. Animation
The effect pattern can be test-reproduced on the screen of the viewer 106 by operating the fader lever 196 of the dialog 190.

In this case, when the fader lever 196 is located at the uppermost position, the background 106 in which the animation effect has not been performed is displayed on the viewer 106. Further, as the fader lever 196 is dragged by the mouse and moved from the top to the bottom, the display image of the viewer 106 shifts to the state of the animation effect. When the fader lever 196 is located at the lowest position, the viewer 106 displays the event of the animation effect in which the foreground and the back ground are set.

As a result, the event of the animation effect can be reproduced at an arbitrary speed by manual operation of the feeder lever 196.

When the AT button 197 is clicked in the animation effect setting state,
First, the fader lever 196 moves to the uppermost position,
Thereafter, it gradually moves to the lower position, and transitions at the set transition time. Thus, the animation button can be automatically reproduced by the AT button 197 under normal reproduction conditions.

Here, in parameter setting section 198 provided in dialog 190, the edge of the switching position is designated.
Parameters for (Edge), parameters for lighting (lighting effect), parameters for trial / shadow (effects such as shadows and bands), and positions for setting effects Various parameters that can be added to the effect, such as parameters related to the location (Location), can be set by clicking a button corresponding to each parameter.

[0229] Further, on the dialog 190, the key button 199 is clicked to enter the chroma mode.
(Chroma) key and / or External key can be set.

(2-15) Modifying an Effect When modifying an event for which an effect has been set, a dialog 190 is opened by double-clicking the modified effect event with the mouse.
The effect parameters that have already been set are displayed in the dialog 190. Here, for example, if the already set effect is a transition effect like “Wipe” shown in FIG. 33A, when the effect event is double-clicked, the event E0 is set to the background. The out point of E0 is searched, and the event E1 is set to the foreground, and the in point of event E1 is searched. As a result, the position of the now line 139 on the time line 95 is immediately set to the out point of the event E0 and the in point of the event E1 for which the transition effect is set, and
It can be confirmed on the viewer 106.

For example, if the already set effect is an animation effect like “Mosaic” (mosaic) shown in FIG. 33 (B), double-clicking the effect event causes the event E1 to become the background. Is set, the in point of the event E1 is searched, and the event E2 is set to the foreground, and the out point of the event E1 is searched.

As a result, the position of the now line 139 on the time line 95 can be immediately set to the in point of the event E1 or E2 in which the animation effect is set.

Thus, when the dialog 190 is opened,
Foreground and background are automatically set for the event to be video-effected on the base line 132, and the end point of the foreground of the event and the start point of the background are automatically searched.

(2-16) Effect Expression Method Here, an effect expression method set for an event on the timeline 95 will be described.

The effects set on the timeline 95 are roughly divided into a transition effect and an animation effect which are used when two events are switched. The transition effect is further divided into a transition system and a transition effect. Divided into flip / tumble systems.

That is, as shown in FIG. 34A, of the transition effects, in the case of the transition system, the base video line 132A of the time line 95 is used.
In addition to displaying the events E1 and E2 as a reference,
The effect EF1 corresponding to the length of time for effecting the effect on the effect line 135 provided on one line of the base video line 132A is displayed together with the effect type name. Further, the boundary between the event E1 and the event E2 is represented by oblique lines. This makes it easy to visually recognize that the cut has been switched from the event E1 to the event E2. Incidentally, transition effects include wipes, page turns, and the like.

As shown in FIG. 34B, in the case of the flip / tumble system in the transition effect,
As in the case of the transition system, a reference event E is displayed on the base video line 132A of the timeline 95.
1 and E2 as well as the base video line 1
Effect line 135 provided on one line of 32A
EF2 according to the length of time to effect
Is displayed together with the effect type name of the effect EF2. Further, the boundary between the event E1 and the event E2 is represented by oblique lines. As a result, it is possible to easily visually recognize that the cut switching from the event E1 to the event E2 is performed by flip / tumble. Further, in the case of the flip / tumble system, since the event image is rotated three-dimensionally with reference to the center line of the image, the internal video (Internal Video) when the image is rotated exactly 90 ° cannot be seen. The effect IV in the overlay line 122
Are displayed.

Next, in the animation effect, a video effect applied to an event applies an effect to one event, or inserts an event having an effect into a predetermined event. The effect is further divided into a standard animation system and a modifiable system (= effect type).

That is, as shown in FIG. 34C, in the case of a standard animation system such as a picture-in-picture system in which an effect event is inserted into a reference event, the base event E1 The event E2, which is displayed on the line 132A and is inserted into the effect, is displayed on the overlay line 13A.
6 is displayed. In this case, at the position where the video effect is applied on the base video line 132A, the state where the animation effect is applied to the event is displayed by displaying a vertical line. It has been done. In this way, the reference event and the insertion event are displayed on separate lines, and a vertical line is displayed at the position where the animation effect is applied. It can be easily visually identified that the effect insertion event is being inserted. In this case, the effect type used for the insertion event is indicated in the effect line 135 by the effect E.
By displaying it as F3, the type of effect for the event can be easily identified visually.

As shown in FIG. 34 (D), in the case of a modi? Ed system in which mosaic processing or the like is performed on one event, events E1 and E2 serving as references are used as base video data.
The effect is displayed on the line 132A, and the effect to be inserted is displayed on the effect line 136 as the effect EF3. In this case, base video line 1

(2-18) Effect Setting Procedure The effect setting for the events arranged on the timeline 95 follows the effect setting procedure by the video editing application software as shown in FIG. 39 and FIG. This is executed under the control of the CPU 21.

That is, in the effect setting procedure, first, in step SP40, the event to which the effect is to be added is arranged on the base video line 132A on the timeline 95 (FIGS. 17 and 18). Here, in step SP41, by clicking on the effect button 159 on the program window 94, a dialog 190 (FIG. 29) for performing various effect settings is displayed on the screen.

Next, in step SP42, a desired pattern is clicked and selected from the effect pattern / bit map displayed on the favorite pattern / display section 192 on the dialog 190. As a result,
The number of the selected pattern is output and displayed in the pattern number column 191A of the pattern number setting section 191 under the control of the CPU 21.

For the effect pattern, if the desired pattern number is already known, the desired pattern number is directly input from the keyboard 2C into the pattern number field 191A of the pattern number setting section 191 and then the enter key is clicked. Can also be selected.

At this point, the CPU 21 determines whether the effect set for the event is an animation effect or a transition effect, and in the next step SP43, the video effect is the animation effect. Step SP to follow in case
Go to 44. In step SP44, first, by pressing the mark-in button 115 and the out button 116 on the viewer 106 at desired positions on the timeline 95, an in-point and an out-point are set for the event, and A range to be effected is designated (FIG. 31A).

Next, at step SP45, the clip CL selected at step SP42 is pasted on the timeline 95 by drag and drop.
As a result, a new event “New Event” is pasted on the overlay video line 136 of the timeline 95 as shown in FIG. When the overlay event is pasted on the overlay video line 136 in this manner, the effect line 1 of the timeline 95 is output.
A selected effect, for example, a picture-in-picture "PinP" is also pasted on 35. As a result, an animation effect can be set for the event of the base video line 132A. (FIG. 31
(B)).

Thus, an animation effect can be set between the in-point and the out-point of the event pasted on the timeline 95 by a simple operation of drag and drop using the mouse 2D.

When the animation effect is set for the event in this manner, step SP46 is executed.
Then, the dialog 190 is closed, and the routine proceeds to the next processing step SP47.

Here, in step SP43, the CPU
If the effect set for the event is determined to be a transition effect by C.21,
The process proceeds to step SP48 under the control of the PU 21, and after setting a transition time using the dialog 190,
In the next step SP49, the selected effect is added to the timeline 95 by drag-and-drop.
Paste on top (FIG. 30 (A)). As a result, the selected effect is pasted on the effect line 135 of the timeline 95, and the base video line 1
A transition effect can be set for the event of 32A (FIG. 30). Thus mouse 2
A transition effect can be set for an event pasted on the timeline 95 by a simple operation of drag and drop using D.
Thereafter, the processing step moves to step SP46.

When the dialog 190 is closed in step SP46, it is next determined in step SP47 whether or not the effect set for the event is to be corrected. If the effect set for the event is to be corrected here, the process moves to step SP50, deletes the effect event once set, returns to step SP41, and executes the video effect setting procedure again from step SP42. cure.

If it is determined in step SP47 that the effect set for the event is not to be modified, the effect setting for the event is completed, and the effect setting procedure ends. This makes it possible to easily set an animation effect or a transition effect for the event read on the timeline 95.

(3) Operation of Embodiment In the above configuration, first, the monitor 2 of the computer 2
By selecting and clicking one of the source selection buttons 102A to 102E on the viewer window 92 displayed on B, a predetermined source device is selected, and a desired editing material, that is, a program, is selected from the source device. Can be read.

Here, a simple operation of dragging a predetermined clip material on the log window 93 and dropping it near the in-point set in the program on the timeline 95 allows the in-point and out-point of the program on the timeline 95. A desired event can be pasted between points.

In this case, as shown in FIG. 23, for example, as a first case, when the in point and the out point are set on the timeline 95 and only the in point is set in the clip material, the timeline and the CPU based on the time code of each of the in and out points of the clip material
The out-point of the clip material is set in accordance with the out-point set in the timeline 95 by the arithmetic processing of 21.

As a second case, the time line 95
When only the in point is set above and the in and out points are set in the clip material, the timeline 9
The CPU 21 sets the out point of the inserted clip material on the basis of the time codes of the in point 5 and the in point and out point of the clip.

As a third case, an in point and an out point are set for a clip, and a time line 95 is set.
When only the OUT point is set above, a value corresponding to the IN point of the inserted clip is set as the IN point of the timeline 95 by the arithmetic processing of the CPU 21 based on the time code of the IN point of the clip. You.

Further, as a fourth case, time line 9
5, the in-point and the out-point are set on the clip 5 and the in-point and the out-point are set for the clip, and the length between the in-point and the out-point of the event on the timeline 95 and the length of the clip material When the CPU 21 determines that the two match, the clip CL is pasted as it is between the IN point and the OUT point on the timeline.

On the other hand, if the CPU 21 determines that the lengths of the IN and OUT points of the event on the timeline 95 do not match the length of the clip material,
The length of the clip material is reset according to the in-point or out-point on the timeline 95 by the arithmetic processing of U21.

[0275] Thus, the CPU 21 performs arithmetic processing based on the time code information of the in point and / or the out point of the clip material to be inserted and the time code information of the in point and / or the out point of the event on the time line 95. ,
By setting the length of the clip material or the in-point and / or out-point of the event on the timeline 95,
A desired clip material can be easily attached on top.

(4) Effects of the Embodiment According to the above configuration, the editing material input from the source device is read out and graphically displayed as an event on the timeline 95 in the form of a band according to the length of the editing material. This allows the user to visually confirm the approximate program length and position.

Further, the program on the timeline 95 can be reproduced via the device control section 96, and the image of the program and the time code at the position of the now line 139 displayed on the timeline 95 during the reproduction can be respectively viewed. This can be confirmed by using the time code 106 and the time code display field 108.

Thus, while checking the image and the time code of the program on the time line 95, the mark-in button 115 and / or the mark-out button 116 are click-inputted to the program by a simple method of inputting the program into and out points. Can be set.

Further, when the clip material is read from the log window 93 and pasted on the timeline 95,
Based on the time code information of the clip material and the time code information of the in-point and / or the out-point set on the time line 95, the length of the clip material is reset by the arithmetic processing of the CPU 21, or By re-setting the time code of the in point and / or the out point on the 95, the insertion event can be reliably pasted at a predetermined position on the time line 95.

(5) Other Embodiments In the above-described embodiment, when a clip material, which is program information of an edit cut, is read out from the log window 93 as a file and is pasted on the timeline 95, the edit area is used.
