Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproducing apparatus, an editing apparatus, a method for controlling a reproducing apparatus, and a method for controlling an editing apparatus.
For example, the present invention can be applied to a non-linear editing device using a recording / reproducing device having a random access function such as a hard disk device. According to the present invention, the upper limit and the lower limit of the operable range of the operator are set at the top and the bottom of all the materials.
By switching so as to correspond to the top and bottom of one material and controlling the access to the recording medium in response to the operation of this operator, the function of the recording medium that can be randomly accessed is fully exhibited and further enhanced Be able to improve usability.

[0002]

2. Description of the Related Art In recent years, in an editing site of a broadcasting station or the like, a recording / reproducing device having a random access function such as a hard disk device or an optical disk device is used instead of an editing operation using a video tape recorder which is difficult to access at random. The so-called non-linear editing work has been adopted.

That is, in this kind of editing work, 1
After recording various materials to be edited on one recording / reproducing apparatus, these materials are selected and an editing point is set while reproducing the various materials thus recorded. In the editing work, each edit cut constituting the edit result is set by setting such edit points. Further, in the editing work, an edit list describing the edit points of each edit cut and the reproduction order of each edit cut is generated, and the edit results are generated by sequentially reproducing each edit cut according to the edit list. It has been made like that.

In an editing operation using a video tape recorder, a desired material is selected and an editing point is set by operating a jog shuttle dial to rapidly feed a magnetic tape, advance a frame, or the like. Further, the editing result is previewed.

On the other hand, in an editing operation using a hard disk device or the like, a GUI (Graphical User
Interface) and a pointing device such as a mouse on this screen can be used to execute this type of processing.

[0006] As described above, although the operation in the editing operation is different, in the non-linear editing using a hard disk device or the like which can be accessed randomly, the whole picture of the material can be grasped more quickly than in the editing operation using a video tape recorder. In addition, the time required for the editing operation can be reduced because the selection of the material and the setting of the editing point can be performed quickly.

[0007]

The operation using the GUI and the pointing device has a disadvantage that the operability is inferior to the operation using the jog shuttle dial.

That is, the jog shuttle dial is a rotary operator that functions as a jog dial or a shuttle dial according to a user's selection operation. The jog dial is an operation element that changes a reproduction position in a time axis direction or a reverse direction by an amount corresponding to a clockwise or counterclockwise rotation operation amount during reproduction of a still image. The shuttle dial is an operator that changes the playback speed in accordance with the clockwise or counterclockwise rotation angle during playback at the standard playback speed.

The jog shuttle dial can intuitively grasp and process a current event in progress and an event temporally before or after the current event by such an operation. It can be considered as an operator that is extremely suitable for a process of selecting a temporally preceding and succeeding frame in the work.

[0010] Thus, it is considered that the nonlinear editing work can be made even more efficient by applying the jog shuttle dial to the nonlinear editing apparatus used for the nonlinear editing work to improve the operability.

At this time, not only the function of the video tape recorder is applied to the non-linear editing device, but also
If we could add functions that would not be possible when using magnetic tapes so that the convenience of a randomly accessible recording medium could be fully demonstrated, the usability of this type of editing device would be even greater. It is thought that can be improved.

The present invention has been made in view of the above points, and is intended to provide a reproducing apparatus, an editing apparatus, and a reproducing apparatus capable of fully exhibiting the function of a randomly accessible recording medium and further improving usability. A control method and a control method for an editing device are proposed.

[0013]

According to the present invention, there is provided a playback apparatus, an editing apparatus, a method for controlling a playback apparatus, or a method for controlling an editing apparatus. The first and second values of the time information in the reproduction result of the recording medium are set so as to correspond to the upper limit and the lower limit, and access to the recording medium is performed according to the operation direction and the operation amount of the operation element. And switches between the first and second values in response to a predetermined selection operation.

The first and second values of the time information in the reproduction result of the recording medium are set so as to correspond to the upper and lower limits of the operable range of the operator, and the operating direction of the operator and If the access to the recording medium is controlled in accordance with the operation amount, the first and second values are set to, for example, the first and last signals of the signal recorded on the recording medium, and the operation is performed in response to the operation of the operation element. Thus, the entire image can be quickly and easily grasped. At this time, by switching the first and second values in response to a predetermined selection operation, the entire material recorded on the recording medium, one material, or the like can be selected and accessed as needed.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings.

(1) First Embodiment (1-1) Configuration of First Embodiment FIG. 1 is a block diagram showing an editing apparatus according to a first embodiment of the present invention. In the editing apparatus 1, the recording / reproducing apparatus 2 is a random-accessible recording / reproducing apparatus for recording / reproducing a video signal and an audio signal accompanying the video signal (hereinafter, these are called AV signals). Operated by control.

That is, under the control of the editor 3, the recording / reproducing device 2 controls the AV signal S1 based on an analog signal or a digital signal or the data-compressed AV signal S1.
Are sequentially recorded on the recording medium 4, whereby various materials to be edited are sequentially accumulated.

The input circuit 5 performs an analog-to-digital conversion process on the AV signal S1 based on the analog signal and outputs the processed signal to the data compression circuit 6, while the A signal S1 based on the digital signal is used.
The V signal S1 is output to the following data compression circuit 6, omitting the analog-to-digital conversion processing.

The data compression circuit 6 compresses the AV signal S1 output from the input circuit 5 to a predetermined data amount and outputs it. Here, the compression format of the data compression is determined in consideration of the recording capacity of the recording medium for recording the AV signal S1, the recording / reproducing speed, the connectivity with other systems, and the like. For example, the DV format 25 [Mbps]
Alternatively, an MPEG (Moving Picture Experts Group) 2 format 50 [Mbps] or the like can be applied as needed.

In this embodiment, the data compression circuit 6 uses a method of MPEG2 to make one GOP (Group Of P
(i.e., ictures) is a single frame, and continuous frames are coded only by intra-frame coding. As a result, in the recording / reproducing apparatus 2, a desired frame can be reproduced and output more quickly than when the inter-frame encoding process is assigned.

Input / output interface (input / output I / F)
7 is an AV signal S output from the data compression circuit 6.
1 is recorded on the recording medium 4. Here, as the recording medium 4, a hard disk, an optical disk, a semiconductor memory device, or the like that can be randomly accessed is applied. In this embodiment, a hard disk is applied.

When recording the AV signal S1 in this manner, the input / output interface 7 uses a simple process to
In response to the access from the editor 3 based on the time code, the corresponding AV signal S1 is reproduced and output in a frame unit, and an address by a frame number is assigned to each frame and recorded. Here, the frame number is a number for specifying one frame by the hour, minute, second, and frame of the time code. At this time,
Under the control of the editor 3, a continuous time code is assigned to each material recorded on the recording medium 4 (that is, the continuously recorded AV signal S1), and a frame number based on the time code is assigned to record each frame.

Further, when the recording of one material by the continuous AV signal S1 is completed, the input / output interface 7 notifies the first frame number and the last frame number by data communication with the editor 3. The material list recorded on the recording medium 4 is updated by the control of the editor 3 in response to the request. Here, the material list is a table necessary for access control of each material recorded in this way from the editor 3 side, and at least the number of each continuous material, the top frame number of each material,
It consists of the last frame number.

The input / output interface 7 also edits the edit list necessary for reproducing the edited result in the editor 3 corresponding to the material list specifying each material to be edited.
In the same manner, the recording is updated on the recording medium 4 by the control of. Here, the edit list is a list necessary for accessing the material recorded on the recording medium from the editor 3 and reproducing it as an edit result, and at least a frame number for specifying an edit point set by an operator and the edit number. It is composed of a number specifying the reproduction order of a series of AV signals (that is, one edit cut) specified by points, a connection form of consecutive edit cuts, and the like.

The input / output interface 7 reproduces the material list and the edit list in response to a request from the editor 3 when the power is turned on, and outputs the material list and the edit list to the editor 3.

When the editor 3 accesses the material list and the edit list output to the editor 3 in this manner, the input / output interface 7 reads the AV recorded on the recording medium in accordance with the read command by the frame number added at the time of recording. The signal S1 is reproduced and output in frame units. Thus, in the recording / reproducing apparatus 2, when outputting the AV signal S1 according to the NTSC system, for example, the read control command is set to 1/30.
The corresponding AV signal S1 is output in response to a second cycle.

The input / output interface 7 directly inputs the data-compressed AV signal S1 from an external device and records it on the recording medium 4 in the same manner as described above.
When outputting the AV signal S1 to the external device in the format in which the data is compressed, the A signal reproduced from the recording medium 4 is used.
The V signal S1 is output directly to an external device.

The data decompression circuit 8 decompresses and outputs the AV signal S1 output from the input / output interface 7, and the output circuit 9 outputs the AV signal S1 to an external device. At this time, the output circuit 9 performs a digital-to-analog conversion process on the AV signal S1 as necessary, and outputs an analog signal.

Thus, in the recording / reproducing apparatus 2, the AV signal S1 recorded on the recording medium 4 can be reproduced and output under the control of the editor 3.

The monitor device 11 can monitor the AV signal S1 output from the recording / reproducing device 2.

The editor 3 controls the operation of the recording / reproducing apparatus 2 by the system control circuit 13 according to the operation of the operator, thereby recording various materials and updating the material list on the recording medium 4.

The editor 3 acquires the material list recorded on the recording medium 4 as necessary and develops it in a built-in memory. The editor 3 issues a control command to the recording / reproducing apparatus 2 by the operation of the operator according to the material list 14 expanded in the memory and according to the edit list 15 created by the operation of the operator, and thereby the material recorded on the recording medium 4. , Edit cuts, etc. The editor 3 instructs the recording medium 4 to record the edit list 15 at a predetermined timing.

The editor 3 displays various information necessary for creating the edit list on the display unit 16 and inputs an operator's operation through the operation panel 17.

As a result, the editing apparatus 1 assigns continuous time codes to the recording medium 4 as shown in FIG.
After recording various materials A, B, and C (FIG. 2A),
The materials A, B, and C are reproduced by the operation of the editor 3 and can be monitored by the monitor device 11. Referring to the monitoring result, an editing point is set by the editor 3 to set editing cuts a, b, c, and d (FIG. 2B), and the editing cuts a, b set in this manner are set. , C, and d, an edit list can be created, and further, edit cuts a, b, c, and d are sequentially reproduced in accordance with the edit list to output an edit result (FIG. 2C). ).

FIG. 3 is a plan view showing an example of a display screen of the display unit 16 displaying various information necessary for creating an edit list in the editor 3. On this display screen, an editing mode (EDIT MODE) area is formed at the bottom, and an assemble (ASSEM)

On the display screen, the remaining area obtained by allocating the editing processing mode is divided into two areas on the left and right from the center, and the area on the left from the center is used for displaying time information and the like on the material, and the area on the right from the center. Are assigned to display time information and the like on the editing result. In the left and right areas from the center, the corresponding items related to the material and the editing result are arranged side by side, thereby improving the usability of the operator. In the regions relating to these materials and the editing results, the corresponding regions are selectively high when outputting the reproduction results for the materials in response to the operation of the operation panel 17 and when outputting the reproduction results for the editing results. The display is made in accordance with the brightness, which also improves the usability.

Here, in the area related to the material on the left side, a display (SOURCE) indicating that it is a display section related to the material is arranged at the center and upper part of the display screen. Further, a time code display area is formed below the display.

Here, in the time code display area, a time code (00: 00: 00: 00) continuous for all the materials for the currently accessed frame (FIG. 2)
Is displayed, and the type of time code is displayed next to the time code (TC CTL U).

L) is shown, which shows that the 123rd material is currently being accessed from among the 456 materials recorded on the recording / reproducing apparatus 2. In addition, in the time code display area, a display (SCOPE) indicating the unit in which the currently accessed frame is being accessed is formed alongside the time code, and all the materials recorded in the recording / reproducing apparatus 2 are targeted. Indication indicating access that was made (AL
L), a display indicating access in units of the currently accessed material (SHOT), and a display indicating access in units of cuts by the set edit points (MARK) are arranged. The display screen displays these displays (ALL) and (SHO) in response to the operation of the operation panel 17.
T) and (MARK) are selectively displayed with high luminance.

On the display screen, information relating to the editing point is displayed below the time code display area. That is, on the display screen, a display indicating an in point (MARK IN), a display of a corresponding time code, and a display indicating an out point (M
ARK OUT) and a corresponding time code display are arranged side by side. Further, below these displays, a display indicating the length between the IN point and the OUT point (MARK DURAT).
ION), and a corresponding time code display is arranged.
On the display screen, in response to the operation of the operation panel 17, the display relating to these editing points is selectively displayed with high luminance.

On the other hand, in the region related to the editing result on the right side, a display (PROGRAM) indicating that it is a display unit related to the editing result is arranged at the center and upper part of the display screen. Further, below the display, a display area for the time code and a display area for the editing point are formed corresponding to the display on the material side. In addition, these time code display areas,
In the display area relating to the edit point, since these pieces of information are information relating to the edit result which is a set of edit cuts, “COT” is substituted for “SHOT” on the material side.
The character “UT” is assigned and displayed, and the display other than the display of this character is formed in the same manner as the display on the material side.

FIG. 4 is a plan view showing the arrangement of main operators on the operation panel 17. The operation panel 17 is configured similarly to an operation panel of an editor used for an editing device using a video tape recorder, and various operators are arranged in addition to the illustrated operators. That is, on the operation panel 17, the operator 1 for selecting a processing target
7A is arranged. Here, these controls 17A are controls (SOURCE) for selecting the material side as a processing target.
And an operator (PR for selecting the edit result side as a processing target)
OGRAM). In the editor 3, the left half and the right half of the above-described display screen are selectively displayed with high luminance in response to the operation of the operation element 17A.

On the operation panel 17, an operator 17B for selecting the object to be processed in more detail is arranged below the operator 17A for selecting the object to be processed. Here, these controls 1
7B is an operator (ALL) for selecting the entire material selected by the operator 17A or the entire editing result as a processing target;
An operator (SHOT) for selecting one of the material or the editing result selected by the operator 17A as a processing target;
The material or the editing result selected by the operation element 17A is constituted by an operation element (MARK) for processing a cut designated by the operation element of the editing point arranged below.

Correspondingly, at the bottom of the operation panel 17, an operator 17C for setting an edit point is arranged.
Here, this operator 17C is an operator (MARK IN) for setting and updating the IN point, an operator (MARK OUT) for setting and updating the OUT point, and a cut specified by the setting of the IN point and the OUT point. An operator (ENTER) registered as an edit cut.

On the operation panel 17, an operator 17D for switching the material being reproduced or the edit cut is arranged on the operator 17C at the editing point. Here, this operator 17D
Is a forward feed operator (INDEX FW) for switching the material or edit cut in the direction along the time axis and cueing.
D) and a reverse feed operator (INDEX R) for switching to a material or an edit cut in a direction going back in the time axis and cueing.
EV).

As shown by reference numeral F in FIG. 5, the editor 3 operates the forward feed operator (INDEX FWD) while selecting the material by operating the operator 17A. It is possible to sequentially switch the material in the direction of the time axis from the position being reproduced, and to perform cueing. Similarly, as indicated by the symbol R, the reverse feed control (INDEX REV) is operated to The source can be switched to the direction in which the time axis is sequentially moved back from the position being reproduced, and cueing can be performed.

On the other hand, as indicated by reference numeral F in FIG. 6, in the state where the editing result is selected by operating the operation element 17A, the operation element (INDEX FWD) of forward feed is selected.
Is operated so that the edit cut can be sequentially switched in the time axis direction from the position currently being reproduced, and a cue can be performed. Similarly, as indicated by a reference character R, a reverse feed operator (INDEX REV) ), The editing cut can be switched in the direction of going back the time axis sequentially from the position currently being reproduced, and the cue can be found. In this operation of the operator (INDEX REV), after the playback position is switched to the beginning of the currently reproduced material and edit cut by one pressing operation, the material and the material are sequentially moved back in the time axis by the subsequent pressing operation. It is made possible to find the edit cut.

On the other hand, on the operation panel 17, on the right side of an operation element 17A for selecting an object to be processed, an operation element 17E for reproduction or the like similar to a video tape recorder is arranged. That is, these controls 17E are recording controls (REC),
An operator for playback (PLAY), an operator for still image pause (STILL), an operator for rewinding (REV), and an operator for fast forward (FF) are arranged.

Thus, in this editor 3,
For example, when the material side is selected by the operation element 17A (SOURCE) and the whole is selected by the operation element 17B (ALL), when one of these operation elements 17D is operated,
The entire selected material can be fast-forwarded, rewound, reproduced, etc. in accordance with the operation element 17D.

Alternatively, for example, the operating element 17A (S
SOURCE) and the operator 17
After one material is selected by B (SHOT), when one of these operators 17D is operated, the selected 1
The same processing can be executed for one material. Further, for example, the operation element 17A (SOU
RCE) to select the material side and the operator 17B
After selecting a cut by (MARK), if any of these operators 17D is operated, the operator 17C at the edit point is operated.
Thus, the same processing can be executed for a cut that has not been registered yet.

On the other hand, for example, the operator 17A (PRO
GRAM) to select the editing result side and to operate
After selecting the whole by 7B (ALL), if any of these operators 17D is operated, the same processing is executed for the whole edited result, so-called preview, recording of the edited result on a video tape recorder, etc. are performed. It has been made executable.

For example, the operator 17A (PROGRA)
M) to select the editing result side, and to operate the operator 17B.
(SHOT), (MARK) for one edit cut, or for a cut that has been set by the edit point operator 17C for the edit result and has not been registered, fast forward and rewind according to the operator 17D. , And can be reproduced.

The operation panel 17 is used to operate the operation device 1 for reproducing or the like.
Below 7E, a mode switching operator 17G for switching the operation mode of the search dial 17F is arranged. Here, this operation element 17G is an operation element (SHT) for setting the search dial 17F to the operation mode of the shuttle dial.
L), an operator (JOG) for setting the search dial 17F to the jog dial operation mode, an operator (DMC) for reducing the degree of speed change with respect to the rotation angle and setting the search dial 17F to the jog dial operation mode, a search dial 17F is constituted by an operator (DPC) for setting the operation mode of the slider.

Here, the operation mode of the slider is such that a rotatable range is set on the search dial 17F, and the rotatable range is set to the change range of the time information in the processing target selected by the operators 17A and 17B. This is an operation mode in which the recording / reproducing apparatus 2 reproduces a processing target by setting the corresponding processing.

Correspondingly, a search dial 17F is arranged below the controls 17G on the operation panel 17, and in the search dial 17F, in the operation mode of the shuttle dial and the slider, for example, as a whole, The rotatable range is limited so that the rotation operation cannot be performed more than 270 degrees. In the operation mode of the jog dial, the limitation of the rotatable range is released by releasing the clutch disposed on the rotating shaft, and the jog dial can be freely rotated. It has been made like that. In the search dial 17F, a rotary encoder disposed on the rotating shaft constitutes an operation amount detecting means, and the operation amount is detected by the rotary encoder.

As a result, in the editor 3, FIG.
As shown in (A) and (D), for example, in a state where the material side is selected by the operation element 17A and the whole is selected by the operation element 17B, the operation mode of the search dial 17F is changed by operating the operation element 17G to operate the slider. When the mode is set, the search dial 17F is rotated in the predetermined rotation operable range so that an arbitrary frame in all the materials can be reproduced. That is, in this case, the search dial 17F can be rotated counterclockwise until it is difficult to rotate, and the first frame in all the materials can be reproduced. On the contrary, it is difficult to rotate the search dial 17F clockwise. Rotate to play the last frame of all the material.

As shown in FIGS. 7B and 7D,
For example, if the material side is selected by the operation element 17A and one material is selected by the operation element 17B, the search dial 17F is operated in accordance with the operation mode of the slider for one material to which the frame currently being reproduced belongs. Any frame in one material can be reproduced.

As shown in FIGS. 7C and 7D,
For example, when the material side is selected by the operation element 17A and the cut is selected by the operation element 17B, the cut set by the operation of the operation element 17C and not yet registered (specified by the IN point IN and the OUT point OUT). (This is a section cut). By operating the search dial 17F in accordance with the operation mode of the slider, an arbitrary frame during the cut can be reproduced.

Further, as shown in FIGS. 8A and 8D, for example, if the editing result side is selected by the operation element 17A and the whole is selected by the operation element 17B, the operation
By rotating the search dial 17F within the range in which G can be rotated, an arbitrary frame in all the edited results can be reproduced.

As shown in FIGS. 8B and 8D,
For example, when the editing result side is selected by the operation element 17A and one editing cut is selected by the operation element 17B, the search dial 1 for one editing cut to which the currently reproduced frame belongs is determined by the operation mode of the slider.
By operating 7F, an arbitrary frame in this one edit cut can be reproduced.

As shown in FIGS. 8C and 8D,
For example, when the edit result side is selected by the operator 17A and the cut is selected by the operator 17B, the operator 17C
With the operation mode of the slider, the search dial 17F is operated with respect to the cut set by the above operation and the cut which has not been registered yet (the cut in the section designated by the IN point IN and the OUT point OUT). Any frame being cut can be played.

In the operation panel 17, in addition to these controls 17A and the like, controls for registering an edit cut registered by operating the control 17B in an edit list, controls for setting a time code, and the like are arranged. These allow the editor 3 to execute the editing work desired by the operator.

In the editor 3, the system control circuit 13 controls the entire operation by executing a series of processing procedures in response to the operation of the operation elements 17A and the like.
This enables the editing apparatus 1 as a whole to execute the processing corresponding to the operation of each operation element described above.

That is, the system control circuit 13 controls the operation of the recording / reproducing device 2 in accordance with the operation of the operating element arranged on the operation panel 17, thereby recording the sequentially input AV signal S1 on the recording medium 4, and thereby The editing material is stored in the recording medium 4. In addition, a material list 14 is created, and the recording / reproducing apparatus 2 is accessed in accordance with the material list 14 to reproduce the material recorded on the recording medium 4. Further, an edit cut is created by setting an edit point based on the reproduction result, and an edit list 15 is created so that an edit result by a set of edit cuts can be output.

In this series of processing, the system control circuit 13 uses the operation element 17A for selecting a processing target.
An operator (SOURCEC) for selecting the material side as the processing target
When E) is operated, the display of the time information on the material side is selectively displayed with high luminance, and the access control of the recording medium 4 is performed according to the operation of the operator according to the material list 14.

That is, in this state, when the operator (ALL) for selecting all materials or all edit cuts as the object to be processed is operated in the operator 17B for selecting the processing object in more detail in this state, the reproduction is performed. The target is set to all the materials recorded on the recording medium 4. In this state, when the playback operation element 17E is operated in this state, the system control circuit 13 sequentially issues a read control command with a frame number added according to the material list, and continues in the order of the time code assigned at the time of recording at this frame number. Specify frames sequentially. When fast forward and rewind operators are operated in place of the playback operator 17E, control commands for reading out with frame numbers are sequentially issued in accordance with the material list 14 in the same manner.
The rewind reproduction result is output from the recording / reproducing device 2. On the other hand, in the case of the pause, the read command with the same frame number is sequentially issued, and the recording / reproducing apparatus 2 outputs the reproduction result of the still image.

On the other hand, when the operation element (SHOT) for selecting one material as the processing object is operated in the operation element 17B for selecting the processing object in more detail, the reproduction object is set to the currently reproduced material. I do. In this state, when the playback operation element 17E or the like is operated, the system control circuit 13 executes processing such as playback, pause, fast forward, and rewind for the currently reproduced material according to the material list 14. Then, a read control command to which a frame number is added is issued in the same manner as described above.

When an operator (MARK) for processing a cut is operated instead, an edit point setting operator 1
The cut set by the operation of 7C is set as a processing target. In this state, the system control circuit 13 operates such that when the playback operation element 17E or the like is operated, the processing target is played back, paused, fast forwarded, rewinded, etc. in accordance with the material list 14 and the set editing point. A read control command is issued in the same manner as described above.

When the operator (PROGRAM) for selecting an edit result as a process target is operated on the control 17A for selecting a process target, the system control circuit 13 changes the display of the time information on the edit result side to high brightness. And selectively controls the access to the recording medium 4 in response to the operation of the operator according to the edit list 15.

That is, in this state, when the operator (ALL) for selecting all materials or all edit cuts as the object to be processed is operated in the operator 17B for selecting the processing object in more detail in this state, the editing is performed. All the editing results according to the list 15 are set as reproduction targets. In this state, when the reproduction operation element 17E is operated, the system control circuit 13 sequentially issues a read control command to which a frame number is added according to the edit list 15, and sequentially successive frames in this frame number in the edit list order. specify. When the fast forward and rewind operators are operated in place of the playback operator 17E, similarly, control commands for reading frame numbers are sequentially issued according to the edit list 15 in accordance with the edit list 15, whereby the editing result is fast forwarded.
The rewind reproduction result is output from the recording / reproducing device 2. On the other hand, in the case of the pause, the read command with the same frame number is sequentially issued, and the recording / reproducing apparatus 2 outputs the reproduction result of the still image.

On the other hand, when the operator (SHOT) for selecting one material as the object to be processed is operated in the operator 17B for selecting the object to be processed in more detail, the edit cut currently being reproduced is set as the object to be reproduced. Set. In this state, when the reproduction operation element 17E or the like is operated, the system control circuit 13 executes processing such as reproduction, pause, fast forward, and rewind for the currently reproduced edit cut in accordance with the edit list 15. Then, a read control command is issued in the same manner as described above.

When an operator (MARK) for processing a cut is operated instead, an edit point setting operator 1
The cut set by the operation of 7C is set as a processing target. In this state, when the reproduction operation element 17E or the like is operated, the system control circuit 13 reproduces, pauses, fast-forwards, rewinds, etc. the processing target in accordance with the edit list 15 and the set editing point. A read control command is issued in the same manner as described above.

In the processing for these materials and the editing results, when the operator 17D for switching the material being reproduced or the editing cut is operated, the system control circuit 13 operates according to the material list 14 and the editing list 15, respectively. Depending on the mode, from the material currently being played and the edit cut,
A read control command is issued by adding a frame number designating the preceding and succeeding materials and the first frame of the edit cut, or adding a frame number designating the material currently being reproduced and the first frame of the edit cut. Accordingly, the system control circuit 13 sequentially switches the material being reproduced and the edit cut in a direction along the time axis or in a direction going back in time in response to the pressing operation of the operation element 17D.

On the other hand, an operator 17 for setting an edit point
When C is operated, a time code is recorded in a register or the like for a frame being reproduced at the time when the operator 17C is operated, and a cut is temporarily registered. An operator to register this cut as an edit cut (ENTER)
Is operated, the temporarily registered cut is registered in the edit list, and various items necessary for creating the edit list, such as a reproduction order, are accepted.

In reproducing the frame desired by the operator in this way, the system control circuit 13 sets the time code and the currently reproduced frame in all the materials in the display area corresponding to the processing target. The position of the material or the position of the currently playing edit cut during the entire edit cut is displayed on the display unit 16.

When the shuttle dial control (SHTL) is operated in a state where the material and the editing result are reproduced by operating the reproduction control 17E in this way, the system control circuit 13 causes the search dial 17F to operate. Is connected, and the operation mode of the search dial 17F is set to the operation mode of the shuttle dial. Thereby, the system control circuit 13 sets the search dial 17F to be rotatable within a predetermined angle range, and the predetermined operation amount of the search dial 17F based on the predetermined reference position is a constant speed change amount in the time information of the reproduction result. The access to the recording medium is controlled in accordance with the operation amount of the search dial 17F.

That is, the system control circuit 13 detects the operation amount at a period of 1/30 second from the rotary encoder arranged on the search dial 17F, and thereby detects the operation amount of the search dial 17F at regular time intervals. At this time, the system control circuit 13 detects the operation amount based on the rotation angle of the search dial 17F with respect to a predetermined reference position (the middle point of the movable range).

When the search dial 17F is rotated from the current position in the clockwise direction, the system control circuit 13
While reading commands are sequentially issued with intermittent frame numbers at time intervals according to this operation amount,
When the search dial 17F is rotated counterclockwise from the current position, a read command is issued by repeating the same frame number a predetermined number of times so that the frame number is reduced by a time interval corresponding to the operation amount. When the operation amount in the counterclockwise direction is equal to or more than a predetermined value, a read command is issued by setting the frame number to decrease stepwise at time intervals corresponding to the operation amount. Thus, the system control circuit 13 can easily select a desired scene by switching the reproduction speed by operating the search dial 17F.

On the other hand, when the jog dial operator (JOG) is operated while operating the playback operator 17E or displaying a still image, the system control circuit 13 causes the search dial 17F to operate. The arranged clutch is released, and the operation mode of the search dial 17F is set to the operation mode of the jog dial. Accordingly, the system control circuit 13 sets the search dial 17F so that the search dial 17F can be freely rotated, and operates the search dial 17F so that the predetermined operation amount of the search dial 17F corresponds to a constant change amount in the time information of the reproduction result. Access to the recording medium is controlled according to the operation amount. When the jog dial operator (JOG) is operated while the playback operator is operated, the system control circuit 13 sets the operation mode to the still image operation mode and accepts the operation of the search dial 17F.

That is, the system control circuit 13 detects the operation amount at a period of 1/30 second from the rotary encoder disposed on the search dial 17F, and thereby, the rotation amount of the search dial 17F at a fixed time interval is used. Detect the manipulated variable. When the search dial 17F is rotated clockwise from the current position with respect to the still image as the reproduction result, the system control circuit 13 sets the frame number from the currently reproduced frame number by the amount of operation detected in this manner. Conversely, when the search dial 17F is rotated counterclockwise from the current position, the read number is incremented and the read command is sequentially issued. The read command is issued sequentially by decreasing the frame number from the middle frame number. As a result, the system control circuit 13 changes the frame currently being played back in the direction along the time axis or in the direction going back in the time axis by the amount corresponding to the rotational operation of the search dial 17F, so that the desired frame can be easily located. Has been made.

On the other hand, the jog dial operator (J
When the following operator (DMC) is operated instead of OG),
The system control circuit 13 similarly operates the search dial 1
The operation mode of 7F is set to the operation mode of the shuttle dial. Further, the system control circuit 13 operates as compared with the case where the shuttle dial operator (SHTL) is operated.
The read commands are sequentially issued while reducing the change in the frame number so that the change in the reproduction speed with respect to the operation amount of the search dial 17F is reduced. Thereby, the system control circuit 13 reproduces, for example, a fast-moving material such as sports by so-called slow motion,
A desired frame can be selected accurately.

When the subsequent operator (DPC) is operated, the system control circuit 13 causes the search dial 1 to operate.
Connect the clutch located on the 7th floor and search dial 1
7F can rotate only a predetermined angle range clockwise and counterclockwise from the current position.

Further, the system control circuit 13 includes
For the currently reproduced processing target specified by 7A and 17B, the total number of frames is detected based on the time codes of the material list and the edit list. That is, when all the materials are being reproduced, the number of frames M from the head of the first material to the last of the last material is detected (FIG. 7A), but one material is reproduced. In this case, the number of frames N from the beginning to the end of the material is detected (FIG. 7B), and when the cut set for the material is being reproduced, the interval between the IN point and the OUT point is reproduced. Number of frames O
Is detected (FIG. 7 (C)).

When all the editing results are being reproduced,
While the number m of frames from the beginning of the first edit cut to the last of the last edit cut is detected (FIG. 8A),
When one edit cut is being played, the number of frames n from the beginning to the end of this edit cut is detected (FIG. 8B), and the cut set for the edit result is played. , The number o of frames between the IN point and the OUT point is detected (FIG. 8C).

Subsequently, the system control circuit 13 reduces the number of frames Mo to 1/2, and sets the time code at a position displaced in the time axis direction from the top of the processing target by the reduced number of frames. Is calculated. Further, the system control circuit 13 issues a read command using the frame number based on the time code calculated in this manner. Accordingly, the system control circuit 13 performs access control so as to reproduce the center frame of the currently reproduced processing target, and the center of the rotatable range which is the current position of the search dial 17F and the current reproduction position of the processing target. To correspond. When the time code is calculated for the center playback position in this way, the editing result is obtained between the edit cuts that are continuously played back.
Because the time code is not continuous, the total number of frames is calculated by adding up the number of frames for each edit cut, and the number of frames for each edit cut is subtracted from the half of the total number of frames in playback order Then, the target time code is calculated.

When the initialization is performed in this manner, the system control circuit 13 continues the processing procedure shown in FIG.
It is executed in a second cycle, so that the upper limit and the lower limit of the operable range of the search dial 17F correspond to the time information of the first and last time for the currently reproduced processing target selected by the operators 17A and 17B. And the playback position is changed in response to the operation of the search dial 17F (FIGS. 7 and 8).

That is, the system control circuit 13 proceeds from step SP1 to step SP2, where the operation amount of the search dial 17F is detected by the rotary encoder of the search dial 17F. Here, the system control circuit 1
3 detects the operation amount based on the rotation angle β based on the center of the initially set rotatable range.

Subsequently, the system control circuit 13 determines the total number of corresponding frames F (M, N, O,
m, n, o), the following formula is executed. As a result, all frames to be processed are uniformly allocated to the rotatable angle α of the search dial 17F, and the number of frames f corresponding to the rotation angle β Is calculated. Where in
t (A) is a function for converting the numerical value A into an integer.

[0088]

(Equation 1)

Subsequently, the system control circuit 13 proceeds to step SP4, calculates the frame number specified by the frame number f from the position of the initial setting, and then proceeds to step S4.
The process moves to P5, issues a read command using this frame number, and then returns to step SP2. The frame number is specified in the time axis direction from the initial setting position or in the direction going back in the time axis according to the operation direction of the search dial 17F.

Thus, in FIG. 10, the system control circuit 13 determines the relationship between the operation of the search dial 17F and the playback position, where n is the total number of frames to be processed, based on the relationship from the head position of each material. Dial 1
When 7F is fully rotated counterclockwise (sign PA
), The access control is performed so as to reproduce the first frame to be processed (frame number 1), and the search dial 17F is fully rotated clockwise (reference PB).
), The access control is performed so that the last frame (frame number n) to be processed is reproduced. Further, when the lens is rotated clockwise by an angle γ from the position fully rotated in the counterclockwise direction (indicated by PC), the number of frames k corresponding to the rotation angle γ represented by the following equation
Access control is performed so as to reproduce the frame of frame number k displaced by -1.

[0091]

(Equation 2)

Thus, the system control circuit 13 causes the top and bottom time information in the reproduction result of the recording medium 4 to be processed to correspond to the upper and lower limits of the operable range of the search dial 17F. The access to the recording medium 4 is controlled in accordance with the operation direction and the operation amount of the search dial 17F.

In this case, the system control circuit 13
In the state where the operation mode of the search dial 17F is set to the operation mode corresponding to the operation element (DPC) in this way, when the processing object is switched by the operation of the operation elements 17A and 17B for selecting the processing object, The same procedure is repeated in the same manner. That is, the system control circuit 13
Are the first and second playback results in the set playback results corresponding to the upper and lower limits of the operable range of the search dial 17F.
Is switched in response to the selection operation of these operators 17A and 17B.

Thus, the system control circuit 13 can operate the operators 17A and 17B as necessary to sequentially narrow down the processing target and easily set an editing point.

(1-2) Operation of First Embodiment In the above configuration, in the editing apparatus 1, the AV signal S 1 as the material to be edited (FIG. 1) is sequentially compressed by the data compression circuit 6. After that, a frame number based on a series of time codes is added and recorded on the recording medium 4 in frame units. Further, at this time, a material list 14 necessary for accessing the material recorded in this way is generated by the editor 3, and the material list 14 is stored in the recording medium 4.

The material recorded on the recording medium 4 in this manner is read out in frame units by a read command to which a frame number for specifying the frame of each material is added, and the data is expanded as necessary and sent to an external device. It is output and displayed on the monitor device 11. This allows the editing apparatus 1 to set an edit cut while confirming the material and execute the editing work.

In the editing cut setting operation, in the editing apparatus 1, the operator (S
When the material side is selected by the operation of “SOURCE” (FIG. 4), the processing is set to the material side, which is the access to the recording medium based on the material list 14, and the display unit 16 (FIG. 3)
In response to this selection processing, the material-side area assigned to the left half of the display screen is displayed with high luminance. In this state, for example, an operator (AL
When the operator (DPC) is selected after selecting L), the search dial 17F is set to the slider operation mode. That is, the search dial 17F is set so that it can be operated clockwise and counterclockwise within a predetermined angle range with respect to the current position, and the frame located at the center of all the materials is reproduced from the recording medium 4.

When the search dial 17F is rotated in this state, the top and bottom values of the time information in the reproduction result correspond to the upper and lower limits of the operable range of the search dial 17F. Once set, access to the recording medium is controlled in accordance with the operation direction and operation amount of the search dial 17F (FIG. 10). As a result, the editing device 1 can rotate the search dial 17F within the limited range where rotation can be performed, and can select from the first frame to the last frame to be processed. Becomes possible. As a result, the characteristics of the randomly accessible recording medium can be fully exhibited, and a desired frame can be narrowed down much more rapidly than when a jog dial or shuttle dial is operated as in the related art. In addition, it is possible to easily and quickly grasp the entire image of the material.

In this way, it is possible to set an edit cut for the frame selected in this way by operating the edit point operator 17C as necessary.

Although the frame selected in this way is a frame at a substantially desired place, if it is desired to select a frame before or after the selected frame, the operators (SHTL), (JOG), ( DMC), the operation mode of the search dial 17F is switched to the operation mode of the shuttle dial and the jog dial, and the previous and next frames are searched, so that a desired material and frame can be selected as necessary. , An edit point can be set and an edit cut can be registered.

At this time, by switching the operation mode of the search dial between the operation mode of the slider and the operation mode of the shuttle dial and the jog dial, the characteristics of the randomly accessible recording medium can be fully exhibited and the conventional video tape can be used. A desired frame can be easily selected with the same operational feeling as a jog shuttle dial by a recorder.

Although the frame selected in this way is a frame at a substantially desired place, if the user wants to select a frame of a material before or after the selected frame, the search dial 17F as a shuttle dial or a jog dial is used. Operation 17D instead of the operation of
By operating (INDEX FWD) and (INDEX REV), the operator 17D
It is possible to switch the material being reproduced in response to the operation of. In this case, a desired material can be quickly selected and searched for from many materials.

As a result, the operator 17D (IN
For the material selected by the operation of (DEX FWD) and (INDEXREV), the operator (SHTL), (JO
G) and (DMC) to select and operate the search dial 17F.
By switching the operation mode to the operation mode of the shuttle dial and jog dial, it is possible to select the desired frame as necessary by searching for the previous and next frame, set the edit point and register the edit cut It becomes possible.

At this time, if one material being reproduced is selected as a processing target by operating the operator (SHOT),
In the operation mode of the shuttle dial and the jog dial, it is possible to prevent the search dial 17F from being turned too much, thereby improving the usability.

When the operator (DPC) is selected while the desired material is selected, the search dial 1
7F is set as a slider operation mode. This time, for the selected one material, with respect to the upper limit and the lower limit of the operable range of the search dial 17F, the first value and the last value of the time information in the reproduction result are set. The values are set to correspond, and access to the recording medium is controlled in accordance with the operation direction and the operation amount of the search dial 17F.

Thus, in the editing apparatus 1, the search dial 17F can be rotated within a limited range in which the rotation operation is possible to select from the first frame to the last frame of one material. Roughly grasp,
Further, it is possible to easily and quickly select a required frame.

As described above, in the editing apparatus 1, the search dial 1 depends on the operation mode of the slider.
When the 7F is operated, by sequentially switching the processing target from one material to one material, it is possible to grasp the entire image of the material and easily narrow down the necessary frames from the entire material.

Instead of narrowing down the search dial 17F in the slide mode for all the materials as described above, after selecting the desired material by operating the search dial 17F in the operation mode of the shuttle dial and the jog dial as in the prior art. By operating the operator (SHOT) and the operator (DPC), even if the search dial 17F is set to the operation mode of the slider with the selected material as a processing target, the necessary frame is grasped by grasping the whole image of the material. In this case, after narrowing down the material in the same manner as in the operation of the conventional video tape recorder, it is possible to narrow down the frame by the slider function unique to the editing apparatus 1.

By the way, although the material is selected in this way, it may be different from the desired material. In this case, the operators 17D (INDEX FWD), (I
By operating the NDEX REV), the material to be processed can be switched to a nearby material and a desired material can be selected.
Further, a desired material can be newly selected from all the materials by operating the operator (ALL) or the like.

In this way, a frame is selected from a desired material, and the operator 17C (MARKIN), (MARK)
OUT), the cut can be temporarily registered, and further, by operating the operator (ENTER), the cut can be registered as an edit cut.

When a so-called preview is to be performed in the registration of the edit cut, the processing target is switched to the provisionally registered cut by operating the operation element 17B (MARK), and the operation element 17E (PLAY) or the like is operated. The cut can be monitored. At this time, the operation mode of the search dial 17F is set to the operation mode of the shuttle dial and the jog dial, and the preview processing can be executed in the same manner as in the editing apparatus using the conventional video tape recorder.

At this time, the operation of the operator (DPC)
The search dial 17F is set to the operation mode of the slider. This time, for the temporarily registered cut, the upper limit and the lower limit of the operable range of the search dial 17F are set.
The first value and the last value of the time information in the reproduction result are set to correspond to each other, and access to the recording medium is controlled according to the operation direction and the operation amount of the search dial 17F.

As a result, if necessary, the search dial 1
By rotating 7F, the entire image of one cut can be easily grasped. In addition, this search dial 17F
By narrowing down the processing target to all materials, one material, and one cut, after grasping the entire image of the material and narrowing down the required frame from the entire material, the result can be easily checked, Further, if necessary, the processing target can be returned to the original one material or all the materials from the cut and confirmed, or the like, so that the temporarily registered cut can be variously examined by a quick process. In this way, the characteristics of the recording medium that can be randomly accessed can be sufficiently exhibited, and the usability can be improved.

Thus, by repeating such processing, the editing apparatus 1 sequentially creates edit cuts from the material,
Further, an edit cut is created from the edit result, and these edit cuts are sequentially registered to create an edit list 15.

In the editing apparatus 1, when the editing result based on the editing list 15 created as described above is confirmed, and when an editing cut is further created based on the editing result, the processing target is edited by operating the operator (PROGRAM). The result is switched to the result, and the recording medium 4 is accessed based on the edit list 15 instead of the access based on the material list 14 on the material side. Further, in response to this selection processing, an area on the editing result side assigned to the right half of the display screen is displayed with high luminance on the display unit 16 (FIG. 3).

In this state, for example, when the operator (ALL) for selecting all the materials is selected and then the operator (DPC) is selected, the search dial 17F is set to the operation mode of the slider, and the clock is set based on the current position. Search dial 1 so that it can be operated only in a predetermined angle range
7F is set, and the frame located at the center of the edited result is reproduced from the recording medium 4.

When the search dial 17F is rotated in this state, the top and bottom values of the time information in the edited result correspond to the upper and lower limits of the operable range of the search dial 17F. Once set, access to the recording medium is controlled in accordance with the edit list 14 in accordance with the operation direction and amount of operation of the search dial 17F (FIG. 10). By rotating the editing result, it is possible to select from the first frame to the last frame of the editing result, and it is possible to easily and quickly grasp the entire image of the editing result. As a result, the characteristics of the randomly accessible recording medium can be fully exhibited, and the usability can be improved.

Even when the editing result side is to be processed, the editing apparatus 1 sequentially edit-cuts the entire frame, narrows down the desired frame, and edits the editing points in the same manner as when the material side is processed. By setting
A desired cut can be temporarily registered based on the editing result, and the temporarily registered cut can be confirmed and registered as an edited cut.

By operating the control 17E, the jog dial, and the search dial 17F as a shuttle dial, the editing result can be confirmed in the same manner as in the case of a conventional video tape recorder editing apparatus.

Further, at this time, the search dial 17F is operated in accordance with the operation mode of the slider in the same manner as in the case where the material side is to be processed, and at the same time, the operator (ALL),
The objects to be processed are sequentially narrowed down by the operations of (SHOT) and (MARK), and furthermore, the feed operator 17D (INDE)
X FWD) and (INDEX REV) can be used to switch the processing target, to easily and quickly grasp and preview the edited result, each edited cut, and the overall image of the cut generated from the edited result, Each edit cut or the like can be examined by comparing with the whole image by narrowing down. In this way, the characteristics of the recording medium that can be randomly accessed can be sufficiently exhibited, and the usability can be improved.

In the editing work, setting and previewing of such edit points occupy a large part of the editing work. Thus, the usability is improved in this way, thereby significantly reducing the time required for the editing work. Can be shortened.

(1-3) Effects of the First Embodiment According to the above configuration, the upper and lower limits of the operable range of the search dial, which is a rotary operator, are set at the top and bottom of all the materials, and By switching so as to correspond to the top and bottom of the material, and by controlling access to the recording medium in response to the operation of this operator, the entire image is easily grasped and a desired frame is quickly selected. It is possible,
As a result, the function of the recording medium that can be randomly accessed is sufficiently exhibited, the usability is further improved, and the time required for editing work can be shortened accordingly.

Further, by switching the processing target according to the material side and the editing result, not only when selecting a cut from the material but also when confirming the editing result, the entire image can be grasped by a quick and simple operation. Can be confirmed,
As a result, the function of the recording medium that can be randomly accessed is sufficiently exhibited, the usability is further improved, and the time required for editing work can be shortened accordingly.

Further, with respect to such a material and an editing result, the processing object is sequentially switched by the same operation so that a desired frame can be narrowed down. At this time, the material side and the editing result side are displayed in a corresponding display form. Is switched to display the time information and the like, the editing apparatus 1 can be used by a unified operation, and the usability can be improved accordingly.

When the search dial is set to the operation mode of the slider and the processing target is switched as described above,
Operators (INDEX FWD), (INDEX RE
By switching the processing target, which is a material and an edit cut, also by the operation V), the material and the edit cut can be quickly selected, and the function of the recording medium which can be randomly accessed is also sufficiently exhibited. The usability is further improved, and the time required for editing work can be shortened accordingly.

At this time, the use of the conventional jog shuttle dial and one operator is shared, so that the function of the recording medium which can be randomly accessed can be sufficiently exhibited and the usability can be improved. In this case, the conventional video tape recorder can be used. The same usability as the editing device can be ensured.

(2) Other Embodiments In the above embodiment, the operation mode of the jog shuttle dial is switched to the operation mode of the slider, so that one rotary operator is shared by three operation modes. However, the present invention is not limited to this, and as shown in FIG. 11, a slide-type operation element may be provided exclusively.

In this case, the position of the button 20 occupying the whole is (3) by pinching and moving the button 20 with a pointing device such as a mouse, or by moving the button 20 by operating the move buttons 21 arranged at both ends. ) Expression,
The recording medium will be accessed. In addition, it is conceivable that the feed operators (INDEX FWD) and (INDEX REV) are arranged on both sides of the move button 21. This makes it possible to provide an editing apparatus with improved usability to an operator who is accustomed to using the conventional GUI-based editing apparatus. In this case, it is conceivable that the other operators are also configured by the GUI.

In the above-described embodiment, a case has been described in which, in the operation mode of the slider, for example, when all the materials are to be processed, the corresponding frames in all the materials are displayed in response to the operation of the operating elements. However, the present invention is not limited to this.For example, when the number of target frames is large, such as when all materials are used, only the first frame of each material is operated as necessary. It may be selectively displayed in response to the operation of the child.

Further, in the above-described embodiment, the case where the operation mode of the slider is switched to the case where the frame displayed so far is switched so that the position of the search dial as the operator and the frame to be displayed correspond to each other is described. However, the present invention is not limited to this, and switches the operation mode of the slider to the operation mode of the slider without changing the displayed frame by correcting the operable range of the search dial or the like for the currently reproduced frame. Thus, the position of the search dial, which is an operator, may correspond to the frame to be displayed.

FWD), (INDEX REV) is operated,
The case of jumping to the beginning of the previous / next material or edit cut and consequently temporarily canceling the operation mode of the slider has been described. However, the present invention is not limited to this. The material and the edit cut may be switched without jumping to the operation mode of the slider by jumping to the position to be performed.

Further, in the above-described embodiment, a case has been described in which all frames to be processed are uniformly allocated to the rotatable angle of the search dial 17F, and the recording medium is accessed. The present invention is not limited to this, and the uniform assignment may be changed as needed, or may be partially changed depending on the operation speed of the operator.

In the above-described embodiment, the case where the edit list and the material list are stored and held in the recording medium has been described. However, the present invention is not limited to this, and may be held on the editor side. May be stored in a separate recording medium such as an IC card.

Further, in the above-described embodiment, the case where the processing target is switched between the material side and the editing result side has been described. However, the present invention is not limited to this, and a plurality of materials may be changed from a material recorded on one recording medium. In some cases, an editing list is created, and in addition to this, the processing target may be switched based on a plurality of editing results.

In the above-described embodiment, the case where a video signal is processed has been described. However, the present invention is not limited to this, and can be widely applied to a case where an audio signal is processed.

Further, in the above-described embodiment, the case where the present invention is applied to the editing device has been described. However, the present invention is not limited to this, and can be applied to a reproducing device such as a DVD.

[0138]

As described above, according to the present invention, the upper and lower limits of the operable range of the operator correspond to the top and bottom of all the materials, the top and bottom of one material, and the like.
