(2) Internal Configuration of Computer In this section, the internal configuration of the computer 2 will be specifically described. As shown in FIG. 2, the computer 2 includes a system bus 5 for transmitting command data and video data, a CPU 10 for controlling the entire computer, and first and second units for performing image processing and the like on an input video signal. 2 video processors 11 and 12, a display controller 13 for managing video data displayed on the monitor 2b and a graphic display for a GUI, an HDD interface 15 for controlling a local hard disk drive (local HDD) 15a, An FDD interface 16 for controlling a two-disk drive (FDD) 16a, a mouse (cursor control device) 2d,
Pointing device interface 1 that generates a control command based on commands from a pointing device such as a dedicated controller 2e and a keyboard 2c.
7. It has an external interface 18 provided with a software driver for performing data communication based on the communication format of the hybrid recorder 3 and the RS-422.

The system bus 5 is a bus for communicating video data, command data, address data, and the like inside the computer 2, and transmits an image data bus 5a for transmitting video data and a command data. And a command data bus 5b. The CPU 10 and the first
And the second video processors 11, 12, the display controller 13, the HDD interface 15, and the FDD interface 16 are connected to each other.
The second video processors 11, 12, the display controller 13, the HDD interface 15, and the FDD interface 16 transmit video data via the image data bus 5a.

On the other hand, the command data bus 5b has a CP
U10, first and second video processors 11, 12,
Display controller 13, HDD interface 15,
The FDD interface 16, the pointing device interface 17, and the external interface 18 are connected to each other (that is, all blocks in the computer 2 are connected), and command data and addresses are transmitted via the command data bus 5b. It is designed to transmit data.

The CPU 10 is a block for controlling the entire computer 2 and includes a ROM 10a storing an operating system of the computer 2, and a RAM 10b storing an uploaded application program and the like. When activating the computer 2, the CPU 10 executes a software program based on the operating system stored in the ROM 10a. When the application program is executed under the operating system being started, the CPU 10 first reads the application program recorded on the hard disk of the hard disk drive 15a and uploads the application program to the RAM 10b. Execute the program.

The first video processor 11 receives the first video signal V2 input to the computer 2,
This is a block for performing data conversion on the first video signal V2 and temporarily buffering the converted video data. Specifically, the first video processor 11 includes a processor controller 11a for controlling the whole of the video processor 11, and a data converter for converting the received analog composite video signal V2 into digital component video data. And a frame memory 11c for temporarily storing video data of several frames transmitted from the data converter 11b.

The processor controller 11a controls the data conversion operation of the data conversion unit 11b by transmitting a control signal to the data conversion unit 11b, and transmits a control signal to the data conversion unit 11b. The data converter 11b extracts a time code from the composite video signal V2. Further, the processor controller 11a sends a control signal to the frame memory 11c to thereby control the frame memory 11c.
The read / write timing and read / write address of c are controlled. Incidentally, regarding the read timing, the processor controller 11a controls the read timing of the frame memory 11c so that the time code transmitted to the display controller 13 and the video data (frame data) correspond to each other.

The data converter 11b converts the analog composite video signal V2 into a component video signal based on a control signal from the processor controller 11a, and then converts the analog component video signal into digital video data. The time code is extracted when converting an analog component video signal into digital video data. The digitally converted video data is sent to the frame memory 11c, and the extracted time code is sent to the processor controller 11a.

Here, the time code is encoded and inserted in two lines of 14H and 16H or 12H and 14H in the vertical blanking period of the composite video signal V2, and is called a so-called VITC (Vertical Interval Time C).
ode). Therefore, when the time code is extracted from the composite video signal V2, when the analog signal is converted into digital data, it can be easily extracted by decoding only the digitally converted time code in the vertical synchronization period. it can. Incidentally, this time code is added when the video signal V2 is output in the hybrid recorder 3.

The frame memory 11c includes a data converter 11
b temporarily stores the video data supplied from b. The read / write timing of the frame memory 11c is controlled by the processor controller 11a as described above. The frame memory 11c is composed of two frame memories and has a total storage capacity of 4 Mbytes. The video data stored in the frame memory 11c is video data consisting of 1520 pixels × 960 pixels, and the frame memory 11c is capable of storing such video data for two frames.

The video data of 1520 pixels × 960 pixels stored in the frame memory 11c is read based on the read control of the processor controller 11a. The video data read from the frame memory 11c is video data of 1520 pixels × 960 pixels, that is, video data whose data amount is thinned out to be 380 pixels × 240 pixels, not video data of all pixels. Here, thinning out the data amount simply means reducing the amount of video data to be read out by reducing the sampling rate for reading out video data from the frame memory 11c to 1/4.
The video data of 380 pixels × 240 pixels read in this way is sent to the display controller 13 via the image data bus 5a.

The second video processor 12 has exactly the same configuration as the first video processor. That is, the video processor 12 is provided with a processor controller 12a for controlling the entire video processor 12.
And the received analog composite video signal V3
Is converted into digital component video data, and a frame memory 12c for temporarily storing several frames of video data transmitted from the data conversion unit 12b. The difference between the first video processor 11 and the second video processor 12 is that the composite video signal V2 is input to the first video processor 11, and the second video processor 1
2 is that the composite video signal V3 is input.

Here, the composite video signal V2 is converted into the input video signal V inside the hybrid recorder 3.
Since the video signal is a video signal in which a time code is superimposed in one vertical synchronization period, the input video signal V input in real time
1 is the same video signal in time. That is, the video data stored in the frame memory 11c is the same video data as that obtained by digitizing the input video signal V1. On the other hand, the composite video signal V3
Is a video signal reproduced from the hybrid recorder 3 according to a command from the computer 2. Therefore, the composite video signal V3 is an asynchronous video signal which is not temporally related to the input video signal V1.

This will be described in detail below. When the operator designates reproduction of desired video data to the computer 2, the computer 2 sends a reproduction command of the video data to the hybrid recorder 3. The hybrid recorder 3 reproduces video data specified by an operator in response to a reproduction command from the computer 2. The hybrid recorder 3 stores a time code corresponding to the video data on a frame basis, and reproduces the time code of the reproduced video data based on the correspondence. Then, the hybrid recorder 3 superimposes the reproduced time code during the vertical synchronization period of the reproduced video data, and converts the resulting video data into an analog composite video signal V3 so that the video data can be transmitted to the computer 2. This is sent to the computer 2 concerned. Since the composite video signal V3 is a video signal reproduced in accordance with an instruction from the operator, the input video signal V1
Are signals that are asynchronous in time.

The composite video signal V3 supplied to the second video processor 12 is supplied to the data converter 12b and the frame memory 12c in the same manner as the composite video signal V2 supplied to the first video processor 11. After predetermined signal processing is performed through the display controller 13 as digital video data of 380 pixels × 240 pixels.

c, video data from the frame memory 12c of the second video processor 12, and CPU
10 are stored based on the timing control signal from the memory controller 13a. The image data stored in the VRAM 13b is stored in a VRA based on a timing control signal from the memory controller 13b based on the internal synchronization of the computer.
The data is read from M13b and is graphically displayed on the monitor 2b. The graphic display displayed on the monitor 2b in this manner becomes a graphic display for the GUI. Here, the image data sent from the CPU 10 to the VRAM 13b is, for example, image data of a window, a cursor, a scroll bar, or the like. By displaying these plural types of image data on the monitor 2b, a graphic display for a GUI can be obtained.

Next, the program view area 42 displayed below the time line display area 40 will be described. In the timeline display area 40, the length of the event display area is basically changed according to the length of each event, so that the length of each event can be visually easily understood. However, since the clip image data of each event is not displayed, it may be difficult to understand what kind of image each event is. Therefore, in the case of the editing system 1, by providing the program view area 42, it is possible to easily understand what kind of image each event is in even in the timeline mode.

The program view area 42 has a view area 42a, a program call button 42b, a send button 42c, and a return button 42d.
The view area 42a is an area for displaying clip image data of the in point or the out point of each event. The sequence of the clip image data displayed in the view area 42a matches the sequence of the events of the program created in the timeline display area 40. As a result, the sequence of events of the program created in the timeline display area 40 can be easily confirmed by the clip image data, and the sequence of images in the program can be easily confirmed. . Incidentally, each clip image data displayed in the view area 42a is image data generated by thinning out the clip image data in the event display area 29, and its image size is displayed in the event display area 29. It is about half the size of clip image data.

The program call button 42b is a button used for inputting a program call instruction for calling an event displayed in the picture mode program display area 30 into the timeline display area 40 and the view area 42a. When the program call button 42b is clicked, a program call is instructed, and the events displayed in the program display area 30 in the picture mode can be called into the timeline display area 40 without changing the arrangement order. Similarly, the same clip image data as the arrangement order of the program display area 30 is called and displayed in the view area 42a. Since the program call button 42b is provided so that a program call can be instructed, a program generated in another mode can be easily called into the timeline mode, and a program generated in another mode can be called. However, it is possible to easily edit the time alignment.

Send button 42c and return button 42d
Is a button used to advance or return the display of the clip image data in the view area 42a. If the created program consists of a plurality of events, not all clip image data can be displayed in the view area 42a. In such a case, all the clip image data can be displayed by operating the forward button 42c or the return button 42d to advance or return the clip image data to the front.

(4) Clip Image Data Management Method Next, a method for storing clip data, event data, and program data will be described. However, the clip data referred to here includes data for displaying the clip image data in the clip display area 28 and data for storing the clip image data. The same applies to event data and program data.

First, the first management record data for clip data, event data and program data will be described with reference to FIG. One piece of the first management record data is provided for each of the clip data, the event data, and the program data. That is, the first management record data for clip data is stored in the clip display area 28.
Is data for managing all the clipped image data displayed in. The first management record data for event data is data for managing all clip image data displayed in the event display area 29. The first management record data for the program data is stored in the program display area 30.
Is data for managing all the clipped image data displayed in. In this embodiment, the first management record data has only one first management record data for clip data, one event data, and one program data.

The first management record data is

The pointer to the data linked before is data indicating a pointer of the management record data linked before the first management record data. If there is no previously linked management record data, its own pointer is stored. The pointer to the data linked later is data indicating a pointer of the management record data linked after the first management record data. If there is no management record data linked later, its own pointer is stored.

The display horizontal size for one page is data indicating the maximum display number of clip image data displayed in the horizontal direction in each of the clip display area 28, the event display area 29, and the program display area 30. is there. In this embodiment, since each of the clip display area 28, the event display area 29, and the program display area 30 can display eleven clip image data, the display horizontal size for one page is "11".
Is stored in the respective first management record data.

The display vertical size for one page is data indicating the maximum display number of clip image data displayed in the vertical direction in each of the clip display area 28, the event display area 29, and the program display area 30. is there. In this embodiment, the clip display area 28, the event display area 29, and the program display area 30 all display only one clip image data.
Data indicating “one” as the display vertical size for the page is stored in each of the first management record data.

The display position on the screen is data for indicating in which display area the clip image data is displayed. In this embodiment, the clip display area 28 is provided at the lower part of the screen, and the event display area 2 is provided at the middle part of the screen.
9, and a program display area 30 is provided in the upper part of the screen. In the case of the first management record data for clip data, data indicating "lower" is stored as the display position on the screen, and for the first management record data for event data, the display position on the screen is " Data indicating "middle tier" is stored,
In the case of the first management record data for program data, data indicating "upper" is stored as a display position on the screen.

The display head position is the clip display area 2
8. In each display area of the event display area 29 and the program display area 30, this is data for indicating from which position the display of the clip image data is started. In this embodiment, 11 is displayed in the clip display area 28.
Clip image data, one in the event display area 29
One clip image data, program display area 30
Since 11 pieces of clip image data are respectively displayed, a total of 33 pieces of clip image data can be displayed. The display positions are managed by numbering the total of 33 display positions in order from the top on the screen. For example, the display positions of the program display area 30 are numbers “1” to “1”.
The display position of “1”, the display position of the event display area 29 are determined to be the display positions of numbers “12” to “22”, and the display position of the clip display area 28 is determined to be the display positions of numbers “23” to “33”. ing. Therefore, in the case of the first management record data for clip data, data indicating "23" is stored as the head of the display position, and in the case of the first management record data for event data, "12" is stored as the display head. In the case of the first management record data for program data, data indicating "1" is stored as the display head position. The total number of links is data indicating the total number of management record data linked after the first management record data.

Next, the second management record data for clip data will be described with reference to FIG. The second management record data for the clip data is data for managing the clip image data displayed in the clip display area 28 for each clip image data. Accordingly, the same number of pieces of second management record data for clip data as the number of clip image data displayed in the clip display area 28 exists. The second management record data for clip data includes a pointer to previously linked data, a pointer to later linked data, an attribute, a clip image data handle, a clip type, and a time code. Data and an index number of the clip image data.

The pointer to previously linked data is data indicating a pointer to management record data linked before this second management record data. In the second management record data, since the first management record data or the second management record data always exists beforehand, the pointer of the data linked earlier is always stored. The pointer to the data linked later is data indicating the pointer of the management record data linked after the second management record data. If there is no management record data linked later, its own pointer is stored.

The attribute is data indicating whether the second management record data is for clip data, event data, or program data. The clip image data handle is data indicating an address at which the clip image data is stored. Accordingly, by referring to the clip image data handle in the second management record data corresponding to the desired clip image data, the address where the clip image data is stored can be obtained. The clip type is data indicating whether the clip image data managed by the second management record data is in-point clip image data or out-point clip image data.

The time code data is data indicating the time code of the clip image data managed by the second management record data. The index number of the clip image data is an index number given to the clip image data. This index number is a number sequentially assigned to all marked clip image data regardless of generation of an in point, an out point, and an event. That is, the number is the same as the clip number displayed on the clip number display section 28d. All the clip image data are managed by this index number.

Next, the second management record data for event data and program data will be described with reference to FIG. The second management record data for event data is stored in the event display area 2
9 is data for managing the clip image data displayed for each clip image data. Therefore, there are as many second management record data items for event data as the number of clip image data displayed in the event display area 29. Similarly, the second management record data for program data is data for managing the clip image data displayed in the program display area 30 for each clip image data. Therefore, the same number of pieces of second management record data for program data as the number of clip image data displayed in the program display area 30 exists.

The second management record data for event data and program data includes a pointer to previously linked data, a pointer to later linked data, an attribute, an event number, and a title. , Subtitle, in-point clip image data handle, in-point clip type, in-point time code data, in-point clip image data index number, out-point clip image data handle, and out It has a point clip type, an out point time code data, an index number of an out point clip image data, a slow type, a symbol type, and a symbol time code data.

The pointer to the data linked earlier, the pointer to the data linked later, and the attribute are the same as those of the second management record data for the clip data described above, so that they will be described here. Is omitted. The event number is a number assigned to the event in the order in which the event was generated. This event number is displayed on the event number display section 29d. The titles and subtitles are titles and subtitles given in advance to registered events, and are stored in actual characters. The title is displayed on the title display section 29g.

The IN point clip image data handle is data indicating the address where the IN point clip image data is stored. Accordingly, by referring to the in-point clip image data handle in the second management record data corresponding to the desired in-point clip image data, obtaining the address where the in-point clip image data is stored. Can be. The in-point clip type is data indicating whether the in-point clip image data managed by the second management record data is the in-point clip image data or the out-point clip image data. It is. In this case, since all of the clip image data is in-point, data indicating the in-point is stored. The in-point time code data is data indicating the time code of the in-point clipped image data managed by the second management record data. The index number of the in-point clip image data is the index number assigned to the in-point clip image data. Similarly to the index number in the second management record data for clip data described above, the index number of the clip image data at this in point is marked regardless of generation of the in point, out point, and event. This is a number sequentially assigned to all clip image data.

The out-point clip image data handle is data indicating an address at which the out-point clip image data is stored. Accordingly, by referring to the out-point clip image data handle in the second management record data corresponding to the desired out-point clip image data, obtaining the address where the out-point clip image data is stored. Can be. The out-point clip type is data indicating whether the out-point clip image data managed by the second management record data is the in-point clip image data or the out-point clip image data. It is. In this case, since the clip image data is all out point data, data indicating the out point is stored. The out-point time code data is data indicating the time code of the out-point clipped image data managed by the second management record data.
The index number of the out-point clipped image data is the index number assigned to the out-point clipped image data. Similar to the index number in the second management record data for clip data described above, the index number of the clip image data at this out point is marked regardless of generation of the in point, out point and event. This is a number sequentially assigned to all clip image data.

The slow type is data indicating whether the event or program managed by the second management record data controls the playback speed using the playback speed setting area 25 or the normal playback speed. It is. The symbol type is data indicating whether or not there is clip image data defined as a symbol during the period between the in-point and the out-point of the event managed by the second management record data. Here, the symbol means representative clip image data for representing the event. The symbol time code data is the time code of clip image data set as a symbol.

Next, how clip image data is managed using the above-described first management record data and second management record data will be described.
This will be described with reference to specific examples shown in FIGS. First, the “marking” line shown in FIG. 9 indicates whether the marking was performed at the in point or the out point. In this example, IN, IN, OUT, I
N, OUT, IN, IN, IN, OUT, IN, OU
This means that marking was performed 15 times T, IN, IN, IN, IN. "Index number (INDEXNO.
The row of “)” indicates the index numbers assigned to the clipped image data of the marked in-point and out-point. This index number is a number that is sequentially assigned to all marked clipped image data regardless of the IN point and the OUT point. Accordingly, as shown in FIG. 9, index numbers "1" to "15" are sequentially assigned to each marked clipped image data. The line of "clip number (clip NO.)" Indicates the clip number displayed in the clip number display area 28d of the clip display area 28. Note that the clip number displayed in the clip number display area 28d is the same as the index number.
The line of “event number (event NO.)” Indicates the event number displayed in the event number display area 29d of the event display area 29. This event number is a number that is automatically assigned in the order of event generation, regardless of the index number and the clip number.

FIG. 10 is a diagram showing which clip image data is displayed in the clip display area 28, the event display area 29, and the program display area 30 when marking is performed as shown in FIG. In the clip display area 28, the clip image data of the index number "1", the clip image data of the index number "6", the clip image data of the index number "7", the clip image data of the index number "12",

That is, the clip image data of the index number “2” is displayed as the event of the event number “1”, the clip image data of the index number “4” is displayed as the event of the event number “2”, and the event of the event number “3” is displayed. The clip image data of the index number "8" is displayed as the event number, and the clip image data of the index number "10" is sequentially displayed as the event of the event number "4".

The clip image data is not displayed in the program display area 30 simply by designating the IN point and the OUT point. In this example, it is assumed that a program as shown in FIG. 10 is created by replacing the four events displayed in the event display area 29. The program is a program that is consecutive in the order of the event of the event number “2”, the event of the event number “4”, and the event of the event number “1”. Accordingly, in the program display area 30, the clip image data of the index number "4" registered as the event of the event number "2", the clip image data of the index number "10" registered as the event number "4", the event The clip image data of the index number “2” registered as the number “1” is displayed.

FIG. 11B shows the event display area 29.
2 shows how clip image data displayed in the table is managed. The management record data 102 is the first management record data for event data. As shown in FIG. 6, the first management record data 102 has data for managing the entire area of the event display area 29 and the position of the clip image data displayed in the event display area 29. I have. Management record data 20 linked after the first management record data 102
2 is second management record data for event data. As shown in FIG. 8, the second management record data 202 includes in-point clip image data indicated by index number “2” and out-point clip image data indicated by index number “3”. Has data for management. Specifically, the second management record data 202
Stores the in-point clip image data handle indicating the address where the in-point clip image data indicated by the index number "2" is stored, and the out-point clip image data indicated by the index number "3". And an out-point clip image data handle indicating the address at which the data is stored.

Similarly, after the second management record data 202, the second clip image data at the in-point with index number "4" and the second clip image data at the out-point with index number "5" are managed. The management record data 204 is linked, and the second
After the management record data 204, the second management record data 208 for managing the in-point clip image data with the index number "8" and the out-point clip image data with the index number "9" is linked. After the second management record data 208, the clip image data of the in point of the index number "10" and the index number "1"
The second management record data 210 for managing the out-point clip image data of "1" is linked.

FIG. 11A shows the program display area 3
10 shows how clip image data displayed at 0 is managed. The management record data 103 is first management record data for program data. As shown in FIG. 6, the first management record data 103 is stored in the program display area 3
0, and data for managing the position of the clip image data displayed in the program display area 30.

After the first management record data 103 for the program data, the second clip image data for managing the in-point clip image data with the index number “4” and the out-point clip image data with the index number “5” is managed. Is linked to the second management record data 204.

After the data 210, the second management record data 20 for managing the in-point clip image data of the index number "2" and the out-point clip image data of the index number "3".
2 are linked.

Here, FIG. 11B showing the management of event data is compared with FIG. 11A showing the management of program data. Clip image data with index number “2”, clip image data with index number “4”, and index number “1”
The order of storage of the clip image data “0” is shown in FIG.
There is no change between (B) and FIG. 11 (A).
That is, this means that the storage position of the clip image data has not been changed at all. The difference between FIG. 11B and FIG. 11A is that the link order of the second management record data has been changed. That is, in the editing system 1, when changing the display order of events, instead of changing the storage position of the clip image data representing the event, the link order of the second management record data that directly manages the clip image data is changed. To change. Thereby, in the editing system 1, there is a special effect that the display order of events can be changed at high speed.

The change of the display order of the clip image data displayed in the clip display area 28 is not limited to the change of the display order of the events. For example, even if the display order of the clip image data is changed by deleting or newly adding the clip image data,
Instead of actually moving the storage position of the clip image data, it is only necessary to modify the link information of the second management record data (that is, the pointer portion to the data linked before and after) to change the link order. The display order can be easily changed.

Next, the marking operation from the first marking to the fifteenth marking will be specifically described below including the operation of each circuit block. Before you start marking,
The first address of the area for storing the work data secured in the RAM 10b already has the first management record data 101 for clip data and the first management record data 10 for event data.
2 and first management record data 103 for program data. However, since there is no second management record data linked to any of the first management record data, its own address is stored in the “pointer to data linked later”.

[First Marking (In Point)] When the first marking is performed, clip image data of 95 pixels × 60 pixels is formed by controlling the reading from the frame memory 11c. The formed clip image data is stored in the free area of the RAM 10b as the clip image data of the index number "1". Simultaneously with the storage, the formed clip image data is displayed in the clip display area 24a. At this time, the second management record data 201 for managing the clip image data is temporarily stored in a register in the CPU 10, but is not stored in the RAM 10b. The reason is that at this point, it is unclear to which management record data the second management record data 201 is linked.

[Second Marking (In Point)] When the second marking is performed, the clip image data of the index number "2" is similarly formed, and the RAM 10b
Is stored in the empty area of At this time, the IN point is marked twice consecutively, so that the incremental display area 24 is displayed.
The clip image data of the index number “1” displayed in “a” is not used as an event. Therefore, the clip image data of the index number “1” displayed in the increment display area 24a is
It is moved to the clip display area 28. Further, by the second marking, it is determined that the second management record data 201 for managing the clip image data with the index number “1” is linked to the first management record data 101 for the clip data. Therefore, as shown in FIG. 11C, the second management record data 201 temporarily stored in the register of the CPU 10 is linked to the first management record data 101 so that the RAM 10
b.

On the other hand, the clip image data of the index number “2” generated by the second marking is newly displayed in the increment display area 24a instead of the clip image data of the index number “1”. 1
Similarly to the second marking, the second management record data 202 for managing the clip image data of the index number “2” is newly temporarily stored in a register in the CPU 10.

[Third Marking (Out Point)] When the third marking is performed, the clip image data of the index number "3" is similarly formed, and the RAM 10b
Is stored in the empty area of Since the third marking is an out point, an event is formed in which the clip image data of the index number "2" is set as the in point and the clip image data of the index number "3" is set as the out point. Accordingly, the clip image data of the index number "2" displayed in the increment display area 24a is copied to the event display area 29 while being displayed in the increment display area 24a. Further, by this third marking, it is determined that the second management record data 202 for managing the clip image data of the index number “2” stored in the register is linked to the first management record data 102 for event data. Is done. Therefore, FIG. 11 (B)
As shown in the figure, the second management record data 202 temporarily stored in the register of the CPU 10
Is stored in the RAM 10b so as to be linked to the first management record data 102.

On the other hand, the clip image data of the index number “3” generated by the third marking is newly displayed in the out-clip display area 24d. The second management record data 202 for managing the clip image data with the index number “3” is
Since the link to the first management record data 102 has been determined, it is not stored in the register in the CPU 10.

[Fourth Marking (In Point)] When the fourth marking is performed, the clip image data of the index number "4" is similarly formed, and the RAM 10b
Is stored in the empty area of Simultaneously with the storage, the formed clip image data is displayed in the clip display area 24a. Similarly to the first marking, the second management record data 204 for managing the clip image data of the index number “4”.
Is temporarily stored in a register in the CPU 10.
Since the clip image data of the index number "3" displayed in the out-clip display area 24d has already been stored, the out-clip display area 24d
Cleared from.

[Fifth Marking (Out Point)] When the fifth marking is performed, the clip image data of the index number "5" is similarly formed, and the RAM 10b
Is stored in the empty area of Similarly to the third marking, since the fifth marking is an out point, an event in which the clip image data with the index number “4” is set as the in point and the clip image data with the index number “5” is set as the out point. It is formed. Therefore, the clip image data of the index number "4" displayed in the increment display area 24a is copied to the event display area 29 while being displayed in the increment display area 24a. In addition, the index number “4” stored in the register is obtained by the fifth marking.
Is determined to be linked to the previously stored second management record data 202. Accordingly, as shown in FIG. 11B, the second management record data 204 temporarily stored in the register of the CPU 10 is linked to the second management record data 202 so as to be linked to the RAM 10b.
Is stored.

On the other hand, the clip image data of the index number "5" generated by the fifth marking is newly displayed in the out-clip display area 24d. The second management record data 204 for managing the clip image data with the index number “5” is
Since the link to the second management record data 202 has been determined, it is not stored in the register in the CPU 10.

[Sixth Marking (In Point)] When the sixth marking is performed, clip image data of index number "6" is formed in the same manner and the RAM 10b
Is stored in the empty area of Simultaneously with this storage, the formed clip image data of the index number "6" is displayed in the clip display area 24a. Similarly to the fourth marking, the second management record data 206 for managing the clip image data of the index number “6” is temporarily stored in a register in the CPU 10. The index number “5” displayed in the out-clip display area 24d is displayed.
Since the clip image data is already stored, it is cleared from the out-clip display area 24d.

[Seventh Marking (In Point)] When the seventh marking is performed, clip image data of index number "7" is similarly formed, and the RAM 10b
Is stored in the empty area of In this case, since the IN point was marked twice in succession, the increment display area 2
The clip image data of the index number “6” displayed in 4 a is moved to the clip display area 28. By the seventh marking, the second management record data 206 stored in the register of the CPU 10 is linked to the second management record data 201 as shown in FIG. Is stored. On the other hand, the formed clip image data of the index number “7” is
It is displayed in the clip display area 24a. In addition, similarly to the sixth marking, the index number “7”
The second management record data 207 which manages the clip image data of FIG. 1 is temporarily stored in a register in the CPU 10. Hereinafter, the ninth to fifteenth markings are performed in the same manner as the first to seventh markings, and thus description thereof is omitted.

(5) Configuration of Hybrid Recorder Next, the hybrid recorder 3 will be described with reference to FIG. As shown in FIG. 12, the hybrid recorder 3 includes a hard disk drive (HDD) 300 that can perform recording and reproduction of an input video signal V1 apparently almost simultaneously, and recording and reproduction on the hard disk drive 300. And a video tape recorder (VTR) 301 for backing up the video data. This makes it possible to reproduce the video at the decisive moment while constantly recording the video, for example, during sports broadcasting, and to record the video on the hard disk drive 300. Alternatively, even if a reproduction error occurs, the video at the crucial moment is not missed by the backup of the video tape recorder 301, so that the recording and the reproduction can be surely performed.

The configuration of such a hybrid recorder 3 will be specifically described below. First, the hybrid recorder 3 is provided with an interface section 302 based on the RS-422 communication protocol. The interface section 302 starts recording from the external interface 18 of the computer 2 and starts recording. Control commands such as recording end, reproduction start, reproduction end and the like are received. This interface part 3
02 transfers the received control command to the CPU 303. The CPU 303 is control means for controlling the overall operation of the hybrid recorder 3, and the interface unit 302
The operation of each unit is controlled in accordance with the control command received from. As a result, the hybrid recorder 3 records the input video signal V1 or reproduces the recorded video signal to output a reproduced video signal V3.

First, a video signal V 1 continuously supplied from a source side of a video camera or the like is input to a first switch 304. A video signal output from the decoder 305 is also input to the first switch 304. The first switch 304 selects a video signal to be recorded on the hard disk drive 300 and the video tape recorder 301 based on a control signal from the CPU 303.
, And selects one of the video signals output from the encoder 306. Since the video signal V1 is normally recorded, the video signal V1 is selected as the first switch 304. By the way, the decoder 305
Is selected when the video signal recorded on the hard disk drive 300 is transferred to the video tape recorder 301 for recording.

[0128] The encoder 306 is connected to the first switch 30.
4 is converted into a digital video signal, and the digitized video signal is converted to an MPEG standard (Moving Picture coding Ex.
perts Group), and outputs the coded video signal to the second switch 307 and the video tape recorder 301.
The second switch 307 has a video tape recorder 3 in addition to the encoded video signal output from the encoder 306.
The video signal output from 01 is input. This second
The switch 306 selects a video signal to be supplied to the hard disk drive 300 based on a control signal from the CPU 303. The switch 306 includes an encoded video signal output from the encoder 306 and a video tape recorder 301
And selects and outputs any one of the video signals output from. Normally, the hard disk drive 30
Since 0 records an encoded video signal, the encoded video signal is selected as the second switch 307. By the way,
When selecting a video signal output from the video tape recorder 301, the video signal recorded on the video tape recorder 301 is transferred to the hard disk drive 300.
And recording.

The video signal selected by the second switch 307 is input to the input buffer memory 308.
The input buffer memory 308 stores a video signal, for example, 1
It has enough storage capacity for 5 frames,
The input video signal is temporarily stored. The hard disk drive 300 has a hard disk array in which a plurality of hard disks are connected in an array, and thus has a sufficient storage capacity for the video signal V1. This hard disk drive 300 has a CPU 303
When a recording operation is instructed by the control signal from the CPU, the video signals stored in the input buffer memory 308 are sequentially read out and stored in the hard disk array in frame units. The hard disk drive 300 has a CPU 3
03, when a reproduction operation is instructed by a control signal, C
The video signal at the location specified by the PU 303 is read from the hard disk array and reproduced. The reproduced video signal is output to an output buffer memory 309 having a storage capacity of, for example, 15 frames and temporarily stored. The output buffer memory 309 sequentially reads out the temporarily stored video signals and stores the read out video signals in the third switch 3.
Output to 10

Here, the hard disk drive 300
The recording and reproducing operations will be specifically described below. In the hybrid recorder 3, the recording and reproducing operations of the hard disk drive 300 are all performed by the CPU.
303. The CPU 303 assigns a time code to each video frame of a video signal to be recorded based on the time code output from the time code generation unit 313, and assigns a recording address to each video frame of the video signal. And C
The PU 303 stores the assigned time code and recording address as a correspondence table. During the recording operation, the CPU 303
Indicates a recording address and a recording command to the hard disk drive 300. Thus, the hard disk drive 300 records the video signal at the designated recording address. On the other hand, when the video signal to be read out is specified by the time code from the computer 2 during the reproducing operation, the CPU 303 refers to the above-mentioned correspondence table and checks where the video frame of the specified time code is recorded (that is, the CPU 303). Check the recording address). Then, the CPU 303 instructs the hard disk drive 300 of the recording address checked together with the reproduction command. Thereby, the hard disk drive 300 reproduces the video signal from the designated address and reproduces the video signal requested by the computer 2. In this way, the CPU 303 stores the correspondence between the time code and the recording address as a correspondence table, so that even if the reproduction position is designated by the time code from the computer 2, the designated reproduction position is promptly reproduced. be able to.

The time code generator 313 described above
Supplies an external time code (EXT. TC) to the CPU 303 as the time code when the external time code (EXT.TC) is supplied from the outside, and generates the time code by itself when the external time code is not supplied. CPU
303.

Next, the input buffer memories 30 provided on the input side and the output side of the hard disk drive 300 are described.
8 and the role of the output buffer memory 309 will be described. The two buffer memories 308 and 309 are buffer members for apparently performing the recording operation and the reproducing operation of the hard disk drive 300 in parallel. The hard disk drive 300 has an input buffer memory 308
Can perform the recording operation at least twice as fast as the speed at which the video signal is taken in, and can perform the reproducing operation at least twice as fast as the speed at which the output buffer memory 309 reads out the video signal. ing. Therefore, if the buffer memories 308 and 309 are provided on the input side and the output side, the input buffer memory 3
08 is capturing a video signal, the hard disk drive 300 can perform a reproducing operation to store the video signal in the output buffer memory 309, and while the output buffer memory 309 is reading the video signal, the hard disk drive 300 can read the video signal. 30
8 to perform a recording operation by reading a video signal. Therefore, the hard disk drive 300
If the buffer memories 308 and 309 are provided on the input and output sides of the hard disk drive 300, the recording operation and the reproducing operation of the hard disk drive 300 can be apparently performed simultaneously.

The description of each part will be continued by returning to FIG. As described above, the encoded video signal output from the encoder 306 is also supplied to the video tape recorder 301. The video tape recorder 301 is provided for backing up the hard disk drive 300, and performs a recording operation or a reproducing operation based on a control signal from the CPU 303. For example, when the hard disk drive 300 is performing a recording operation, the hard disk drive 300 operates for recording back-up.
01 records a video signal input in parallel with the recording operation of the hard disk drive 300 on a video tape.
When the hard disk drive 300 is performing a reproducing operation in response to an instruction from the CPU 303, the hard disk drive 300 operates for playback back-up, so that a video signal of the same video frame as the video signal reproduced by the hard disk drive 300 is recorded on the video tape. Playback and output.

The recording and reproducing operations of the video tape recorder 301 are also managed by the CPU 303 as in the case of the hard disk drive 300, but in the case of a video tape recorder, the position is determined by an address like a hard disk drive. Because it cannot be specified, CPU3
03 indicates the time code itself instead of the address information. That is, the video tape recorder 301 performs recording by adding a time code given from the CPU 303 at the time of recording, and determines a read position based on the time code specified by the CPU 303 and performs a reproducing operation at the time of reproduction.

The video signal reproduced from the video tape recorder 301 is input to the third switch 310 in the same manner as the video signal reproduced from the hard disk drive 300. The third switch 310 is a CPU 303
Is to select a video signal to be output as the reproduced video signal V3 based on the control signal from the CPU. That is, the third switch 310 is connected to the hard disk drive 30.
0 and the video tape recorder 30
One of the video signals reproduced in step 1
The selection is made based on the control signal from 303. Normally, a video signal reproduced by the hard disk drive 300 is selected. The case where the video signal on the video tape recorder 301 side is selected means that an error has occurred in the video signal on the hard disk drive 300 side.

The video signal selected by the third switch 310 is supplied to the decoder 305. The decoder 305 decodes a video signal that has been compression-encoded in frame units, and decodes an input video signal based on the MPEG standard. The decoder 30
Reference numeral 5 converts the decoded digital video signal into an analog video signal, and outputs this to the first time code adding unit 311.

The first time code adding unit 311 outputs the CP
Based on the time code supplied from U303, a time code is added to the vertical synchronization period of the video signal output from decoder 305. However, if the video signal output from the decoder 305 is a video signal reproduced by the video tape recorder 301, the time code has already been added, so the time code is not added, and the video signal is output by the hard disk drive 300. A time code is added only for a reproduced video signal. The time code added to the video signal matches the time code assigned at the time of recording. The video signal to which the time code is added by the first time code adding unit 311 is output to the outside as the reproduced video signal V3 and is also sent to the computer 2.

The hybrid recorder 3 outputs the input video signal V1 in addition to the reproduced video signal V3.
Is output. The video signal V2 is a video signal obtained by adding a time code to the input video signal V1 by the second time code adding unit 312. In this case, the second time code adding unit 3
Reference numeral 12 adds a time code to the vertical synchronization period of the input video signal V1 based on the time code output from the CPU 303, and outputs this as a video signal V2.
At that time, the second time code adding unit 312 adds the time code to the video signal V1 so that the correspondence between the time code and the video frame to which the time code is added becomes the same as the video signal V3. This is because, for example, when a time code “00: 01: 23: 45” is added to a certain video frame in the first time code adding unit 311, the same video frame as the video frame that matches the video frame in the video signal V 1 is used. Time code "0
0: 01: 23: 45 ".

As described above, the hybrid recorder 3 transmits the video signal V1 to the hard disk drive 300.
While the video signal V3 can be reproduced from the hard disk drive 300, so that the recording operation and the reproduction operation can be performed almost simultaneously. In the case of the hybrid recorder 3, a video tape recorder 301 is provided for backing up the hard disk drive 300, so that even if any trouble occurs on the hard disk drive 300 side, the recording and reproducing operation can be performed reliably. It has been done.

(6) Reproduction speed setting (6-1) Reproduction speed setting area Next, the reproduction speed setting of the event will be described. In the editing system 1, the event playback speed can be set in frame units using the playback speed setting area 25 in either the picture mode or the timeline mode. This makes it possible, for example, to set slow playback for an event at the moment when a home run is hit in a baseball broadcast, and to perform slow playback of the event of the home run scene to more realistically express the movement of butter and the whereabouts of the ball Can be provided to the viewer. In addition, since the playback speed can be set in frame units, for example, a relatively slow slow playback can be set in a scene where a pitcher throws a ball, and a relatively slow slow playback can be set in a scene at the moment when a butter hits a ball. By setting a different slow playback in the event, more powerful video can be provided to the viewer.

Here, this point will be specifically described with reference to FIG. First, the reproduction speed setting area 25 shown in FIG. 13 becomes operable by clicking the reproduction speed setting button 22h in the timing display area 22. The playback speed setting area 25 includes a learn button 25a, a speed fit button 25b, a normal playback speed setting button 25c, and an event number display section 25.
d, event duration display 25e, timeline scale display 25f, time runner display 25g, point display 25h, in-point timecode display 25i, and out-point timecode display 25j.
And a remaining memory indicator 25k.

The learn button 25a is a button used to set a reproduction speed by using a dedicated controller 2e described later. After the learn button 25a is clicked, when the playback speed information is input using the dedicated controller 2e, the speed information is stored, and the playback speed of the event is set. Speed fit button 25b
Is a button used for automatically setting the reproduction speed by inputting the length from the in-point to the out-point (so-called duration) from the keyboard 2c.
After the speed fit button 25b is clicked, if a duration value is input from the keyboard 2c, an optimum reproduction speed is automatically set based on the duration value.

The normal playback speed setting button 25c is used to cancel the setting of the playback speed. When the normal playback speed setting button 25c is clicked after designating the event for which the playback speed is set, the set playback speed is canceled and the normal playback speed, that is, the normal speed is set. The event number display section 25d is an area for displaying an event number of a specified event. The displayed event number is the same as the event number displayed on the event number display section 29d of the event display area 29.

The event duration display section 25e
The length of the specified event from the in point to the out point,
That is, it is an area for displaying the duration. The event duration display section 25e displays the duration in frame units. The timeline scale display section 25f is an area indicating a scale, ie, a scale, for visually representing the duration of a specified event. The scale displayed on the timeline scale display section 25f is a frame unit.

When the playback speed is set by the dedicated controller 2e to be described later,
Or, a position display unit that displays which position in the event is currently set or reproduced when previewing the event for which the reproduction speed is set. An icon 25ga in the form of a running human is displayed on the time runner display section 25g, and the current setting is made according to the display position of the icon 25ga based on the scale of the timeline scale display section 25f. Alternatively, the position in the event being played can be specified. Therefore, the operator can easily understand which position is set or reproduced visually based on the position of the icon 25ga. Also, in this case, the icon 25ga sequentially moves along the scale from the in point to the out point along with the progress of the setting or reproduction. At this time, the icon 25ga is set in accordance with the set reproduction speed. Since the moving speed of the event changes, the operator can easily visually confirm which part of the event has the higher reproduction speed and which part has the lower reproduction speed.

The point display section 25h is an area indicating whether there is another in point or out point set during the editing operation between the in point and the out point of the designated event. In the point display section 25h, when such another in point or out point exists, the pointer 25ha is displayed at the position. Thus, the operator can easily grasp the existence of another editing point based on the presence or absence of the pointer 25ha. The in-point time code display section 25i and the out-point time code display section 25j are areas for displaying the time codes of the in-point and out-point of the selected event, respectively.

The memory remaining amount indicator 25k clicks the learn button 25a, sets the playback speed using the dedicated controller 2e, and sets the playback speed to the CPU 10.
This area indicates the remaining amount for the maximum learn duration when stored in the RAM 10b. Since the storage area allocated for setting the playback speed for one event is predetermined, the remaining capacity can be easily calculated by checking the remaining capacity of the storage area. By providing such a memory remaining amount indicator unit 25k, the remaining amount of the memory can be visually recognized, so that it is possible to prevent the setting of the reproduction speed exceeding the maximum learn duration time.

(6-2) Dedicated Controller Next, the dedicated controller 2e used for setting the reproduction speed will be described with reference to FIG. As shown in FIG. 14, the dedicated controller 2e includes a search dial 400, which is a rotary encoder, in addition to a plurality of operation buttons.

A variable button 413 is a button pressed when the search dial 400 is to be operated in the variable mode or when the motion control lever 401 is to be operated. When the variable button 413 is pressed once, the right variable indicator 414 is turned on and the search dial 400 is set to the variable mode. Is enabled, and when pressed again, the left and right variable indicators 414 are turned off and the search dial 400 is turned off.
And the motion control lever 401 becomes unusable.

The preview button 415 is a button used to preview a selected event or program. When the preview button 415 is pressed while an event or program is selected, a playback start command of the event or program is output to the hybrid recorder 3, and the video signal of the event or program is displayed on the playback video screen 23a. .

The cursor button 416 is an up button,
A button for moving a cursor when selecting clip image data in the clip display area 28, the event display area 29, or the program display area 30. The button comprises four buttons: a down button, a left button, and a right button. is there. Enter button 417 has 2
Types of functions are assigned. One is a function of inputting a registration instruction when registering a new event from the in point to the out point set in the playback video marking area 27 (same as the new event button 33 displayed on the monitor 2b). The other is a function for inputting a transmission instruction when transmitting a selected event or program.

The search dial 400 is a rotary encoder for inputting reproduction speed information according to the rotation operation of the operator. The search dial 400 operates in the three modes of the shuttle mode, the jog mode, and the variable mode by pressing the shuttle button 411, the jog button 412, and the variable button 413 as described above. First, in the shuttle mode, depending on the rotational position of the search dial 400, the speed increases from -100 times to +10 times.
Playback speed information up to 0x speed can be input. In this mode, the search dial 400 is in a click state at the position of a still image, + 10 × speed and −10 × speed. Also, in the jog mode, reproduction speed information from -1x speed to + 1x speed can be input depending on the rotation position of the search dial 400. Also, in the variable mode, it is possible to input reproduction speed information from -1 times speed to +3 times speed depending on the rotational position of the search dial 400. In this mode,
The search dial 400 is in a click state at the position of a still image and +1 times speed. A jog mode in which a fine playback speed can be set by narrowing the control range in this way, a shuttle mode in which a wide range of settings can be set by a coarse playback speed setting, and a variable mode in which the setting range on the plus side is widened are selected. With such a configuration, the operator can switch the reproduction speed according to his / her desired reproduction speed and freely set the reproduction speed.

The motion control lever 401 is a slide encoder for inputting reproduction speed information according to a slide operation by an operator. By sliding the motion control lever 401 up and down, it is possible to input reproduction speed information from a still image to +1 times speed. The motion control lever 40
A range expansion button 401a is provided on both sides of the device 1. The reproduction speed information that can be input by pressing the range expansion button 401a can be expanded to a range from -1x speed to + 3x speed. As described above, since the playback speed information from the still image to the +1 times speed can be input by the motion control lever 401, the operator can freely set the playback speed within the range. Further, as a mechanism for inputting playback speed information, a search dial 400 of a rotary operation type and a motion control lever 401 of a slide operation type are provided, so that an operator can select a user-friendly one and input the playback speed information. Input can be performed, and usability can be improved.

The exclusive controller 2 described here
e, instruction information input from various operation buttons, the search dial 400 and the motion control lever 40.
The playback speed information input from 1 is sent to the CPU 10 via the pointing device interface 17. As a result, the CPU 10 performs an operation control according to the instruction information and performs a reproduction operation according to the reproduction speed information for the designated event. When the learn button is pressed, the CPU 10 sets the playback speed information in the RAM 1 as the playback speed of the specified event.
0b.

By the way, when storing the reproduction speed information,
For example, it is stored in a data format as shown in FIG. That is, speed data is stored for each video frame from the in point to the out point of the designated event. The speed data is stored in the search dial 400 or the motion control lever 401.
And digital data decoded by the pointing device interface 17. During reproduction, the CPU 10 reads out the speed data stored in this format and controls the reproduction speed. At that time, the CPU 10 performs an operation of v = 10 ^{(N / 32-2)} , where N is the speed data and v is the playback speed,
The value obtained as a result is defined as the reproduction speed. Therefore, for example, when the speed data N is "64", the reproduction speed is "1.0", and when the speed data N is "32", the reproduction speed is "0.1".

(6-3) Setting Method of Reproduction Speed Next, a setting procedure for setting the reproduction speed using the reproduction speed setting area 25 will be described. First, there are roughly three methods for setting the reproduction speed. The first method is to input reproduction speed information (speed data) from the keyboard 2c without using the dedicated controller 2e. This is a method of inputting information (speed data), and the third method is a method of inputting reproduction speed information using the dedicated controller 2e without specifying an event.

In the case of the first method, a desired event whose reproduction speed is to be set is specified from the event display area 29 by performing a click operation. Next, the reproduction speed setting button 22h in the timing display area 22 is clicked. Thus, the designated event number and the duration are displayed in the reproduction speed setting area 25. Next, the speed fit button 25 in the reproduction speed setting area 25 is set.
Click b. As a result, the playback speed information can be input from the keyboard, and the operator inputs the playback speed information. In this case, the reproduction value is not actually input, but a duration value is input. By this operation,
The optimum playback speed according to the duration value is automatically set for the event. After that, if the event is to be previewed, the preview button 32 may be clicked. To save the set playback speed, the new event button 33 or the replace button 34 may be clicked.

In the case of the second method, a desired event whose reproduction speed is to be set is specified from the event display area 29 by performing a click operation. Next, the reproduction speed setting button 22h in the timing display area 22 is clicked. Thus, the designated event number and the duration are displayed in the reproduction speed setting area 25. Next, the learn button 25a in the reproduction speed setting area 25 is clicked. As a result, the playback speed can be set, and the playback speed information is input by operating the motion control lever 401 or the search dial 400 of the dedicated controller 2e. The input playback speed is determined by the CPU.
10 are sequentially stored in the RAM 10b. Thereafter, if the setting of the reproduction speed is to be ended, the mark-out button 27f of the reproduction video marking area 27 or the mark-out button 410 of the dedicated controller 2e is pressed at the position to be ended, and the setting of the reproduction speed ends. In order to save the set playback speed, the new event button 33 or the replace button 34 may be clicked.

In the case of the third method, first, the learn button 402 of the dedicated controller 2e is pressed at a desired position while watching the playback video screen 23a of the playback video display area 23. As a result, the in-point is set and the playback speed can be set.
By operating the motion control lever 401 or the search dial 400, the playback speed information may be input.
The input reproduction speed is stored in the RAM 10b of the CPU 10.
Are sequentially stored. Thereafter, if the setting of the reproduction speed is to be ended, the mark-out button 27f of the reproduction video marking area 27 or the mark-out button 410 of the dedicated controller 2e is pressed at the position to be ended, and the setting of the reproduction speed ends. In order to save the set playback speed, the new event button 33 or the replace button 34 may be clicked.

(7) Pre-roll mode Next, the pre-roll mode provided in the editing system 1 will be described. Usually, when generating an event, the operator clicks the mark-in button 24c and the mark-out button 24f of the recording video marking area 24 while watching the video data displayed on the recording video screen 21a, and enters and exits. Indicate a point. As a result, in the editing system 1, the video data from the designated in point to out point is registered as an event. To confirm the registered event, the operator clicks and designates the event displayed in the event display area 29, and then clicks the preview button 32. As a result, the playback operation of the event is started, and video data from the in point to the out point of the event is displayed on the playback video screen 23a.

By the way, when instructing the in point of the event, the operator operates the mark-in button 24c while watching the video data displayed on the recording video screen 21a to designate the in-point. Due to a delay in the operation of the in button 24c, the in point may be specified after the scene to be registered as an event. For example, when registering a scene in which a home run is hit in a baseball broadcast as an event, it is generally desirable to register as an event a period from when the pitcher throws the ball to when the ball hit by the butter stands in. Since it is not known whether or not it is a home run scene until the ball hit by the butter stands in,
Inevitably, it is delayed to indicate the in point. Such an event whose in point is delayed does not include an important scene, so the event must be corrected.

Therefore, in the case of the editing system 1, the reproducing operation is automatically started from a position a predetermined time before the position of the in point designated by the operator, so that the marking point can be easily corrected. A pre-roll mode is provided. The pre-roll mode will be specifically described below. First, the time used in the pre-roll mode, that is, the time for shifting the reproduction start point forward from the in point specified by the operator (hereinafter, this is referred to as a key-up time) can be freely set in the environment setting of the menu. It has been made like that. When setting the key-up time, an environment setting prepared as a menu is called, and a key-up item in the environment is selected. By selecting this key-up item,
A screen for setting up a key as shown in FIG. 16 is displayed on the screen. On this setup screen, if the user clicks on the set time display area 500 and then inputs the time to be set as the setup time from the keyboard in units of seconds, the time is displayed in the set time display area 500 and is provisionally set.

When a button in a desired direction among the jog buttons 501 next to the set time display area 500 is clicked, the time shifts in that direction in units of seconds, so that the jog button 501 is used. Then, the user may input a queue time. When the setting button 502 is clicked after the input of the setup time in this manner, the time displayed in the set time display area 500 is formally registered as the setup time.
Specifically, the input key-up time is stored in the RAM 10
b is stored in the storage area for environment setting data. In addition,
When the cancel button 503 is clicked, the time displayed in the set time display area 500 is reset.
It is now possible to enter a new setup time. By the way, when the setting button 502 is clicked, the keyboard setting screen automatically disappears from the screen.

When the pre-roll button 22g in the timing display area 22 is clicked in the state where the key-up time is set in this way, the activation of the pre-roll mode is instructed. Starts. In addition,
To cancel the pre-roll mode, the pre-roll button 22g is clicked again to instruct the end of the pre-roll mode.
2g turns off and the pre-roll mode is released.

When the operator clicks the mark-in button 24c of the recorded video marking area 24 in the state where the pre-roll mode is activated, the in-point is specified, and the clipped image data specified as the in-point is displayed in an increp mode. It is displayed in the area 24a. At the same time, the set up time is read out, and as shown in FIG. 17, the time code at the position shifted by the up time from the time code at the position designated as the in point is calculated. .
By outputting a playback command to the hybrid recorder 3 with the calculated time code position as a playback start point, the editing system 1 automatically starts a playback operation from the playback start point. Since the reproduced video signal V3 is displayed on the reproduced video screen 23a, the operator can easily correct the IN point by clicking the mark-in button 27c of the reproduced video marking area 27 while watching the reproduced video screen 23a. can do. After that, if the mark-out button 27f is clicked to indicate an out point and the new event button 33 is clicked, video data in a section from the in point to the out point is registered as an event.

If the pre-roll mode is activated in advance in this way, for example, when a ball hit by a batter stands in during baseball broadcasting, the mark-in button 2
Even when the in point is designated by clicking 4c, the reproduction operation is automatically performed from a position a predetermined time before the in point, so that the reproduction side mark-in button 27c is clicked while watching the reproduction screen. The in-point can be easily corrected only by designating the in-point. For example, if the in point is corrected when the pitcher throws the ball, an event including a desired scene, such as the moment when the butter hits the ball, can be easily created in real time.

(8) Work Data Folder In this section, the work data folder will be described. In the editing system 1, work data related to events, programs, and the like generated by the editing operation is usually stored in the RAM 10b. However, when the application program is ended to end the editing operation, The work data is downloaded to a hard disk drive 15a provided inside the computer 2 and stored on the hard disk in the hard disk drive 15a. At this time, the work data is stored in a hierarchical structure called a folder.

Here, this point will be specifically described with reference to FIG. As shown in FIG. 18, work data relating to events, programs, and the like are stored in a hierarchical structure called a folder. This folder is
It is almost the same as the directory in MS-DOS or the like, and the work data folder 600 is the highest hierarchy.
Lower folders 601 to 603 are formed below the hierarchy of the work data folder 600, and each data file is stored while being managed in a hierarchical structure. Note that the work data folder 600 uses this editing system 1
Is formed on the hard disk drive 15a by the computer 2 when the computer is started.

First, the clip image data displayed in the clip display area 28, the event display area 29, the program display area 30, or the like is stored as a clip image file below the hierarchy of the clip folder 601 formed below the work data folder 600. Are stored in units of clip image data. The content of the clip image file is the clip image data itself, and video data indicating the clip image is written. As the file name of the clip image file, as shown in parentheses, a name obtained by adding an extension ".pic" to an index number assigned to each clip image data is used.

The symbol image data registered as a representative clip image in the event is the symbol folder 60 formed below the work data folder 600.
The symbol image files are stored in units of symbol image data below the second layer. Video data indicating a symbol image is written as the contents of the symbol image file. As a file name of the symbol image file, as shown in parentheses, a name obtained by adding an extension “.pic” to an event number including the symbol image is used.

In the work data relating to the program, the lower-order folder is not formed, and the work data
It is stored as a program file below the layer of 00.
In this program file, the event numbers of the events constituting the program are written in order, and by referring to the program file, it is possible to know which event the program is formed by. You can do it. As the file name of the program file, a name obtained by adding an extension ".dat" to "PROG" indicating that the file is a program file is used.

In the work data relating to the event, the lower folder is not formed, and the work data folder 60 is directly formed.
It is stored as an event file below the level of 0. In this event file, the clip numbers of the in point and the out point are sequentially written for each event number. The clip number can be found. As the file name of the event file, a name obtained by adding the extension “.dat” to “EVNT” indicating the event file is used.

The work data relating to the clip image data is also stored directly as a clip file under the hierarchy of the work data folder 600 without forming a lower folder. In this clip file, the index number and time code of the clip image data are written in order for each clip number, and by referring to the clip file, each clip image data is stored in the image of which index number. It is possible to know whether it is formed by data. As the file name of the clip file, a name obtained by adding the extension “.dat” to “CLIP” indicating that the file is a clip file is used.

Speed data indicating the playback speed of an event set using the playback speed setting area 25 (FIG. 1)
5) is stored as a slow data file under the hierarchy of the slow data folder 603 formed below the work data folder 600 in units of events. In this slow data file, speed data as shown in FIG. 15 is written for each frame, and by referring to the slow data file, the reproduction speed set for the event is set. You can get to know. As the file name of the slow data file, as shown in parentheses, a name obtained by adding an extension ".dat" to an event number assigned to each event is used.

Thus, in the editing system 1,
When ending the application program, work data relating to events, programs, and the like generated by the editing operation are stored in a hierarchical structure on the hard disk of the hard disk drive 15a. As a result, when the application program is restarted, these work data stored on the hard disk are read out and the program display area 3 is read.
The same clip image data as before termination can be displayed in 0, the event display area 29, etc., and the state before application program termination can be restored. Also, by storing the work data in this manner, the work data is read out later and the EDL (edit / edit
An editing list such as a decision list can be output.

(9) Description of Operation of Computer In this section, the operation of the computer 2 in each process will be described using a flowchart. The flow chart used in the following description is basically a CPU 10
Is explained.

[Initial Operation] First, an initial operation of the computer 2 will be described with reference to FIG. First step SP
When the execution of the application program is designated by the operator at 1, the CPU 10 of the computer 2
Starts operation. In the next step SP2, since the application program is stored on the hard disk of the hard disk drive 15a, the CPU 10 uploads the application program to the operation RAM 10b provided in the CPU 10.

At the next step SP3, the CPU 10
The application program uploaded to the AM 10b is executed. In the next step SP4, the CPU 10
Secures a memory area in the RAM 10b for storing a plurality of clipped image data, edited data, and the like generated by an editing operation to be performed. At this time, the first management recorder for clip data, event data and program data as shown in FIG. 11 is also generated in the RAM 10b. Next step SP
In 5, the CPU 10 generates a work data folder for storing work data relating to a program or an event to be generated by an editing operation to be performed on the hard disk of the hard disk drive 15a.

At the next step SP6, the CPU 2 displays a graphic display for the GUI on the monitor 2b.
Reference numeral 10 transfers the graphic data to the VRAM 13b in real time in synchronization with the internal clock of the computer 2. As a result, in the next step SP7, the VRAM
The same graphic as the graphic data stored in 13b is displayed on the monitor 2b. Next step S
In P8, the CPU 10 determines whether to display the video signal V2 on the recording video screen 21a. This determination is made based on the designation of the video display by the operator.
If the video display is not specified, it is determined that the editing operation is not to be performed, the process proceeds to step SP16, and the process ends. In the normal case, since there is a video display designation for performing the editing operation, the process proceeds to step SP9 and shifts to the display processing of the video signal V2.

At step SP9, the CPU 10 instructs the hybrid recorder 3 to output the video signal V2 by outputting an RS-422 control command to the hybrid recorder 3. The hybrid recorder 3 that receives this generates a video signal V2 by adding a time code to the input video signal V1 and sends it to the computer 2. In the next step SP10, the composite video signal V2 input to the data converter 11b is input.
, And converts the composite video signal V2 into digital component video data. The converted video data is input to the frame memory 11c and is temporarily stored in frame units. The extracted time code data is supplied to the processor controller 11a, and is sent out to the CPU 10 via the processor controller 11a.

In the next step SP11, the video data stored in the frame memory 11c is stored in the VRAM 13
b. The video data to be transferred is video data reduced to 380 × 240 pixels because the number of samples read from the frame memory 11c is reduced. At this time, by arbitrating the image data bus 5a, image data for GUI in addition to video data is transferred from the CPU 10 to the VRAM 13b. Also at this time VRAM
By updating the video data stored in the monitor 13b in real time, the video data can be displayed on the monitor 2b in real time.

In the next step SP12, the VRAM 13
The image data and video data stored in b are displayed on the monitor 2b in real time. Next step SP1
In 3, it is determined whether or not the video data displayed on the recording video screen 21 a is to be recorded in the hybrid recorder 3.
The PU 10 makes the determination. This determination is made based on the click operation of the recording start button 31a by the operator.
That is, if the recording start button 31a is clicked, it is determined that video data is to be recorded, and the process proceeds to the next step SP14. If the recording start button 31a is not clicked, it is determined that video data is not to be recorded, and the process proceeds to step SP16. finish.

[0187] At step SP14, the CPU 10 sends a recording start command to the external interface 18.
The external interface 18 receiving this converts the recording start command into a communication format conforming to the RS-422 standard and sends it to the hybrid recorder 3. Thereby, the hybrid recorder 3 starts the recording operation of the input video signal V1. In the next step SP15, the recording operation was started by the hybrid recorder 3, so that
The CPU 10 determines that all the initial settings have been completed, and ends the procedure of the initial operation as shown in this flowchart.

[Marking on Recording Side] Next, the marking using the recording video marking area 24 will be described with reference to the flowchart shown in FIG. Note that this marking can be more easily understood by referring to the description of FIGS. 9 to 11. First, when the procedure of the initial operation shown in FIG. 19 is completed, this marking operation can be performed, and the process is started from step SP20.
In step SP21, the CPU 10 determines whether or not a new marking has been made. The determination as to whether or not the marking has been made is made based on whether or not the mouse 2d is clicked in a state where the cursor is positioned within the area of the mark-in button 24c or the mark-out button 24f of the recording video marking area 24. At that time, an interrupt command is generated by the click operation of the mouse 2d.
The CPU 10 determines the marking according to the generation of the interrupt command. If the result of this determination is that the mark-in button 24c has been clicked, it is determined that the in-point has been designated and the process proceeds to step SP22. If the mark-out button 24f has been clicked, it has been determined that the out-point has been designated. Then, it proceeds to step SP30.

At step SP22, clip image data of the IN point is generated. The in-point clipped image data is generated by reading the video data stored in the frame memory 11c into the VRAM 13b. At this time, since the data amount is thinned out to 1/16 by reducing the number of read samples, clip image data having an image size of 95 pixels × 60 pixels is generated. At step SP23, the in-point clipped image data stored in the storage area for the clip display area of the VRAM 13b is read out and displayed in the clip display area 24a.

In step SP24, the CPU 10 determines whether or not the marking in step SP21 is the first in-point marking. As a result, if it is the first marking, the process returns to step SP21, and if it is the second or more marking, the process proceeds to step SP25. In step SP25, the CPU 10 determines whether or not the clip image data marked earlier is the clip image data of the IN point. As a result, if the clip image data previously marked is the clip image data at the in point, the process proceeds to step SP26, and if the clip image data previously marked is the clip image data at the out point, the process proceeds to step SP27. Proceed to.

At step SP26, the clip image data of the in point marked earlier is moved to the clip display area. That is, since the IN point is marked twice consecutively, the clip image data previously marked is not used as an event, and the clip display area 2
Moved to 8. At this time, as shown in FIGS. 9 to 11, the second management record data for the clip image data moved to the clip display area 28 is generated.

On the other hand, in step SP27, the CPU 10
Determines whether an event has been generated based on the clip image data of the out point marked earlier. As a result, if the event has been generated by the previous marking, the process proceeds to step SP29. If the event has not been generated by the previous marking, the process proceeds to step SP28. At step SP28, the clip image data of the out point displayed in the out clip display area 24d by the previous marking is moved to the clip display area 28. This is because the clip image data of the out point generated by the previous marking is not used as an event, but may be used in the future, so that it is left as a marking history.
On the other hand, at step SP29, the clip image data of the out point displayed in the out clip display area 24d is cleared. In this case, the clip image data displayed in the out-clip display area 24d is
Since it is already used as an out point for the event,
This is because there is no need to display any more.

On the other hand, since the marking of the out point is detected by the judgment in step SP21, step S
When the process proceeds to P30, clip image data of the out point is generated here. The clip image data at the out point is also generated by reading the video data stored in the frame memory 11c into the VRAM 13b. Also in this case, the data amount is reduced to 1 /
By thinning out to 16, clip image data of 95 × 60 pixels is generated. In step SP31, the VRAM
The out-point clip image data stored in the storage area for the out-clip display area 13b is read out and displayed in the out-clip display area 24d.

In the next step SP32, the CPU 10
Determines whether the marking at step SP21 is the first out point marking. as a result,
If it is the first marking, return to step SP21,
If it is the first or later marking, the process proceeds to step SP33. In step SP33, the CPU 10 determines whether or not the clip image data marked earlier is the clip image data of the IN point. As a result, if the clip image data marked earlier is the clip image data of the in point, the process proceeds to step SP34, and if the clip image data marked earlier is the clip image data of the out point, the process proceeds to step SP36. Proceed to.

At step SP34, the CPU 10 registers, as an event, a section from the previously marked in point to the later marked out point. In this way, in the editing system 1, when the out point is marked after the in point, it is automatically registered as an event. At this time, as shown in FIGS. 9 to 11, the second management record data relating to the event is generated. In the next step SP35, the generated clip image data of the in point of the event is copied to the event display area 29, and the clip image data is displayed in the event display area 29.

On the other hand, in step SP36, the CPU 10
Determines whether an event has been generated based on the clip image data of the out point marked earlier. As a result, if the event has been generated by the previous marking, the process proceeds to step SP38. If the event has not been generated by the previous marking, the process proceeds to step SP37. In step SP37, the out-point clip image data generated by the previous marking is moved to the clip display area 28. This is because the clip image data of the out point generated by the previous marking is not used as an event, but may be used in the future, so that it is left as a marking history. On the other hand, at step SP38, the in-point clipped image data displayed in the incremental display area 24a is cleared. This is because the event is generated by the clip image data displayed in the clip display area 24a and the clip image data of the out point previously marked, so that the clip image data displayed in the clip display area 24a is This is because there is no need to display it any more because it will not be used in the future.

Step SP26, step SP28, step SP29, step SP35, step SP37
Alternatively, when the processing of step SP38 ends, the CPU 10
Proceeds to step SP39, where it is determined whether or not to end the marking operation. If the marking operation is to be continued, the process returns to step SP20 to repeat the processing, and if the marking operation is to be ended, the process proceeds to step SP20.
Proceeding to 40, the process ends.

[Marking on Reproducing Side] Next, in the case where marking is performed using the reproduced video marking area 27 while watching the video signal V3 reproduced from the hybrid recorder 3, the flowchart shown in FIGS. It will be described using FIG. First of all, this marking
The process starts from a state where clip image data is already stored. Step SP5 entered from step SP50
In step 1, the CPU 10 determines whether clip image data in the clip display area 28 has been designated. At this time, when the mouse 2d is double-clicked (two consecutive click operations) while the cursor is at the display position (28a) of the clip image data, the CPU 10 determines that the clip image data has been designated. As a result, if the clip image data is specified, the specified clip image data is displayed in the reproduction video marking area 27 in the next step SP52. That is, if the in-point clip image data has been designated, it is displayed in the clip display area 27a, and if the out-point clip image data has been designated, it is displayed in the out-clip display area 27d.

In the next step SP53, the CPU 10
Refers to the time code of the designated clip image data, and sends a control command for still reproduction of the video data of the time code to the external interface 18. The external interface 18 that receives this,
The still playback command is converted into a communication format of the RS-422 standard and transmitted to the hybrid recorder 3. Thus, the hybrid recorder 3 checks the recording address by referring to the correspondence table between the time code and the recording address based on the received time code, and reads out the video data from the position of the recording address, thereby obtaining the designated video data. To play. This video data is sent to the second video processor 12 in the computer 2 as a video signal V3.

In the next step SP54, the time code is extracted from the video signal V3 in the second video processor 12, and image processing for converting the video signal V3 into digital component video data is performed. Note that the converted video data is
Is temporarily stored in the frame memory 12c in the video processor 12. In the next step SP55, the still playback video data stored in the frame memory 12c is reduced to 380 pixels × 240 pixels and then VR
Transfer to AM 13b. In the next step SP56, the reproduced video data stored in the VRAM 13b is displayed on the reproduced video screen 23a. In this case, the hybrid recorder 3 transmits not the real-time video data but only the still video data corresponding to the designated clip image data.
In a, a still image is displayed.

At the next step SP57, the CPU 10
Determines whether playback of the still video data displayed on the playback video screen 23a has been instructed.
At this time, if the preview button 32 is clicked while still video data is displayed on the playback video screen 23a, the CPU 10 determines that playback has been instructed. As a result, when a reproduction instruction is given, the CPU 10 sends a reproduction start command to the external interface 18 in the next step SP58. Upon receiving this, the external interface 18 sends the playback start command to the R
The communication format is converted to the S-422 standard communication format and transmitted to the hybrid recorder 3. As a result, the hybrid recorder 3 reads out the video data in order from the recording address corresponding to the video data displayed on the playback video screen 23a, thereby performing normal playback following the video data displayed on the playback video screen 23a. Generate video data. The reproduced video data is a video signal V
3 as the second video processor 1 in the computer 2
2 is sent.

At the next step SP59, the CPU 10 determines whether or not marking has been performed. The determination as to whether or not marking has been performed is determined by the playback video marking area 27.
Mark-in button 27c or mark-out button 27
This is performed based on whether or not the mouse 2d is clicked in a state where the cursor is located in the area f. At this time, since an interrupt command is generated by the click operation of the mouse 2d, the CPU 10 determines the marking according to the generation of the interrupt command. As a result of the determination, if the mark-in button 27c is clicked, it is determined that the in-point has been designated, the process proceeds to step SP60, and if the mark-out button 27f is clicked,
It is determined that the out point has been designated, and the flow advances to step SP63.

At step SP60, clip image data of the IN point is generated. The in-point clipped image data is generated by reading the video data stored in the frame memory 12c into the VRAM 13b. At this time, since the data amount is thinned out to 1/16 by reducing the number of read samples, clip image data having an image size of 95 pixels × 60 pixels is generated. In the next step SP61, the VRAM 13b
The in-point clipped image data stored in the storage area for the clip display area is read out and displayed in the clip display area 27a. Next step SP
At 62, the in-point clipped image data previously marked and displayed in the clip display area 27a is moved to the clip display area 28. It should be noted that the marking is not made first, and the incremental display area 27a
This processing is not performed if the clip image data has not been displayed in the first step. When the processing in step SP62 ends, the CPU 10 proceeds to step SP70.

On the other hand, if the processing has proceeded to step SP63 for marking the out point, clip image data of the out point is generated here. The clip image data at the out point is also generated by reading the video data stored in the frame memory 12c into the VRAM 13b. Also in this case, when reading, the data amount is set to 1
By thinning out to / 16, clip image data of 95 pixels × 60 pixels is generated. In step SP64, VRA
The clip image data of the out point stored in the storage area for the out clip display area of M13b is read out and displayed in the out clip display area 27d.

At the next step SP65, the CPU 10
Determines whether the previously marked clip image data is clip image data of the IN point. As a result, if the clipped image data previously marked is the clipped image data at the in-point, step SP6 is executed.
The process proceeds to step SP67 if the previously marked clip image data is the clip image data at the out point. In step SP66, the CPU 10
Determines whether to register as a new event.
This determination is made by the operator using the new event button 3
3 is performed based on the click operation. If the new event button 33 is clicked and an event registration is instructed, the process proceeds to step SP68. If the new event button 33 is not clicked and no event registration is instructed, the process proceeds to step SP67.

In step SP68, the CPU 10 registers a section from the in point to the out point as an event. As described above, in the editing system 1, when the OUT point is marked after the IN point and the new event button 33 is clicked, the section from the IN point to the OUT point is registered as a new event. At this time, as shown in FIGS. 9 to 11, the second management record data relating to the event is generated. In the next step SP69, the generated clip image data of the in point of the event is displayed in the event display area 2.
9 and the clip image data is displayed in the event display area 29. When this process ends, the CPU
10 proceeds to the next step SP70.

On the other hand, if the processing proceeds to step SP67 because the clip image data generated by the previous marking is the clip image data of the out point, the processing proceeds to step SP67. The clip image data is moved to the clip display area 28. This processing is not performed if the marking has not been made first and the clip image data has not been displayed in the out-clip display area 27d. When this process ends, the CPU 10 proceeds to step SP70. At step SP70, the CPU 10 returns to the playback video screen 23a.
It is determined whether or not an instruction to stop the reproduction of the video data displayed in is given. This determination is made by the dedicated controller 2e
Is determined based on whether or not the stale button 408 is pressed. If playback stop has not been instructed, the process returns to step SP59 and repeats the process. If playback stop has been instructed, the process proceeds to the next step SP71. At step SP71, the CPU 10 sends a reproduction stop command to the external interface 18. The external interface 18 having received this command sends the playback stop command to the RS-42.
The data is converted into a communication format of two standards and transmitted to the hybrid recorder 3. This enables Hybrid Recorder 3
Stops the reading operation of the video data and stops the reproducing operation. When the processing in step SP71 ends, the CP
U10 moves to step SP72 and ends the marking process.

[Trimming] Next, the process of designating the generated event to change the in point or the out point, that is, so-called trimming, will be described with reference to the flowchart shown in FIG. It is assumed that this flowchart starts from a state where an event has already been generated. First, step SP81 entered from step SP80
In, the CPU 10 determines whether or not the clip image data in the event display area 29 has been designated. At this time, when the mouse 2d is double-clicked (two consecutive click operations) while the cursor is at the display position (29a) of the clip image data, the CPU 10 determines that the clip image data has been designated. as a result,
If the clipped image data is specified, in the next step SP82, the CPU 10 refers to the time code of the specified clipped image data, and outputs a reproduction command for still reproduction of the video data of the time code to the external interface. The data is sent to the hybrid recorder 3 via the face 18. Based on this playback command, the hybrid recorder 3 plays back the designated video data to generate playback video data, so that playback video data corresponding to the designated clip image data is displayed on the playback video screen 23a. You.

At the next step SP83, the CPU 10 determines whether or not the shuttle button 23b of the reproduced video display area 23 has been pressed. This determination is made based on whether or not the mouse 2d is clicked while the cursor is at the position of the shuttle button 23b. As a result, if the shuttle button 23b has been pressed, the process proceeds to the next step SP84, where the CPU 10
It is determined whether 3b has been dragged. This decision
The operation is performed based on whether or not the shuttle button 23b has been moved by moving the cursor while the shuttle button 23b is clicked. As a result, if the shuttle button 23b is dragged, the process proceeds to the next step SP85, where the CPU 10 calculates the moving direction and distance of the cursor. Then, the CPU 10 calculates the time code of the designated video data based on the obtained direction and distance and the time code of the video data currently displayed on the reproduced video screen 23a. Specifically, if it is the right direction, the time code of the designated video data is calculated by adding the time code of the moving distance to the time code of the currently displayed video data, and if it is the left direction, The time code of the designated video data is calculated by subtracting the time code of the moving distance from the time code of the currently displayed video data.

[0210] At the next step SP86, the CPU 10 sends a reproduction command for reproducing the video data of the obtained time code to the hybrid recorder 3 via the external interface 18. Next step SP
At 87, the hybrid recorder 3 reproduces the video data of the designated time code based on the reproduction command, and the reproduced video data of the designated time code is displayed on the reproduced video screen 23a.

At the next step SP88, the CPU 10 determines whether or not marking has been performed. The determination as to whether or not marking has been performed is determined by the playback video marking area 27.
Mark-in button 27c or mark-out button 27
This is performed based on whether or not the mouse 2d is clicked in a state where the cursor is located in the area f. As a result of the determination, if either the mark-in button 27c or the mark-out button 27f is clicked, the process proceeds to step SP89, and if neither is clicked, the process returns to step SP83 to repeat the processing. Step SP89
Then, the marked clipped image data is generated. This clipped image data is stored in the frame memory 12c.
Is generated by reading out video data stored in the VRAM 13b. At this time, since the data amount is thinned out to 1/16 by reducing the number of read samples, clip image data having an image size of 95 pixels × 60 pixels is generated.

In the next step SP90, the VRAM
The clip image data stored in 13b is read out and displayed in the clip display area 27a or out clip display area 27d of the reproduction video marking area 27. Specifically, if it is marked as an in point, the clip image data is displayed in the clip display area 27a, and if it is marked as an out point, the clip image data is displayed in the out clip display area 27d. . Next step SP91
Then, the CPU 10 determines whether or not the new event button 33 has been pressed. This determination is made based on whether or not the mouse 2d is clicked in a state where the cursor is located at the position of the new event button 33. As a result, if the new event button 33 has been pressed, step S
Proceeding to P92, if the new event button 33 has not been pressed, proceed to step SP94.

At step SP92, the in-point or out-point is replaced with the clip image data marked at step SP88, and this is registered as a new event. For example, if the in point is marked in step SP88, the section from the new in point to the already registered out point is registered as a new event, and the out point is marked in step SP88. For example, the section from the already registered IN point to the new OUT point is registered as a new event.
At this time, as shown in FIGS. 9 to 11, second management record data relating to the event is newly generated. In the next step SP93, the clip image data of the in point of the new event is displayed in the event display area 29. When this process ends, the CPU 10 moves to the next step SP97 and ends the trimming process.

On the other hand, if the flow proceeds to step SP94 because the new event button 33 has not been pressed, the CP
U10 determines whether or not the replace button 34 has been pressed. This determination is made based on whether or not the mouse 2d is clicked in a state where the cursor is located at the position of the replace button 34. As a result, the replace button 34
If the button has been pressed, the process proceeds to step SP95. If the replace button 34 has not been pressed, the process proceeds to step SP95.
Returning to P83, the process is repeated. In step SP95, the CPU 10 sets the in-point or the out-point in step SP95.
Replace with the clip image data marked at 88. That is, in this case, the content of the second management record data relating to the event is simply replaced with the marked in-point or out-point clipped image data, and the content of the original event is not registered but a new event is registered. Just update. In the next step SP96, the updated clip image data of the in point of the event is displayed at the position of the original event in the event display area 29. When this process ends, the CPU 1
In step SP97, the process proceeds to the next step SP97, and the trimming process ends.

[Program Creation] Next, a process for creating a program using the generated events will be described with reference to a flowchart shown in FIG. It is assumed that the flowchart starts from a state in which an event has already been generated. First step S
In step SP101 entered from P100, CP
U10 determines whether an event has been designated. At this time, the CPU 10 moves the cursor to the event display area 29.
When the mouse 2d is double-clicked (two consecutive click operations) in the display position (29a) of the clip image data, it is determined that the event has been designated. As a result, when an event is specified, in the next step SP102, the CPU 10 sets the specified event to an active state, that is, a movable state.

At the next step SP103, the CPU 10
Determines whether the cursor has been moved while the mouse 2d is still clicked, that is, whether the mouse 2d has been dragged. As a result, if dragged, in the next step SP104, the moving direction and distance of the cursor are calculated. In the next step SP105, the CPU 1
0 changes the display position of the clip image data of the designated event based on the calculated direction and distance.
Note that this step SP103 to step SP105
Since the processing up to this step is performed promptly, the clip image data of the event appears to move on the screen of the monitor 2b together with the cursor.

At the next step SP106, the CPU 10
Determines whether the click button of the mouse 2d is released, that is, whether the click is released. If the result of this determination is that the click has not been released, step S
Returning to P103, the process is repeated, and if the click is released, the process proceeds to the next step SP107, where the position of the cursor when the click is released is calculated.
In the next step SP108, based on the calculated cursor position, the CPU 10 determines whether or not another event is displayed on the right side of the display position of the event specified by the cursor position. As a result, if another event is displayed on the right side, step SP1
09, and if no other event is displayed on the right side, the process proceeds to step SP110. Step SP10
In step 9, the CPU 10 moves the display position of another event displayed on the right side further to the right side so that the specified event can be inserted. When this is over, C
PU10 moves to step SP110.

At step SP110, the CPU 10
Program display area 30 designated by cursor
In the upper position, the clip image data of the specified event is displayed. In the next step SP111, the CPU
Step 10 updates the data content of the second management record data relating to the program in accordance with the event insertion by step SP110. Specifically, the pointer portion to the data linked before or after in the second management record data is corrected. Note that there is no second management record data for the newly inserted event, so that this is newly generated. When this process ends, the CPU 10 moves to the next step SP112 and judges whether or not to continue the program creation process, and if so, proceeds to step SP101.
If the processing is repeated, and the program creation processing is to be ended, the processing moves to step SP113 to end the processing.

[Pre-Roll] A pre-roll operation for automatically starting a reproduction operation from a position a predetermined time before a next designated marking point and correcting the marking point will be described with reference to flowcharts shown in FIGS. 25 and 26. Will be explained. It is assumed that the flowchart starts from a state where the hybrid recorder 3 has started the recording operation of the video signal V1 and a state where the video signal V2 is displayed on the recording video screen 21a. First, step S entered from step SP120
In P121, the CPU 10 determines whether or not the activation of the pre-roll mode is set. This decision
Pre-roll button 22 in timing display area 22
This is performed based on whether or not g has already been clicked and activation of the pre-roll mode has been designated. Next step S
In P122, the CPU 10 determines whether or not the above-described key-up time has already been set as the pre-roll time in the environment setting. This determination is made in the RAM 10b
This is performed based on whether or not the storage time for environment setting data in the storage area is stored. As a result of these determinations, if activation of the pre-roll mode is instructed and the pre-roll time is set, the CPU 10
Proceeds to the next step SP123.

In step SP123, the CPU 10
Mark-in button 2 in recording video marking area 24
It is determined whether or not 4c is clicked to mark the in-point. As a result, if marking of the in-point has been performed, the process proceeds to the next step SP124, where clip image data of the in-point is generated. In addition,
The clip image data is generated by reading video data stored in the frame memory 11c into the VRAM 13b. At this time, since the data amount is thinned out to 1/16 by reducing the number of read samples, clip image data having an image size of 95 pixels × 60 pixels is generated.

In the next step SP125, the VRA
The clipped image data stored in M13b is read out and displayed in the incremental display area 24a of the recorded video marking area 24. Next step SP12
At 6, the CPU 10 calculates a time code for the key-up. Specifically, while referring to the time code of the clip image data at the designated IN point and referring to the set up time, the position shifted from the designated IN point by the time corresponding to the up time (that is, the reproduction time). Calculate the time code of (start point). In the next step SP127, the CPU 10 issues a reproduction command for reproducing video data in real time from the position of the calculated time code to the external interface 18.
To send to. External interface 18 receiving this
Converts the playback command into a communication format conforming to the RS-422 standard and sends it to the hybrid recorder 3.
As a result, the hybrid recorder 3 sequentially reads the video data from the recording address corresponding to the designated time code, thereby generating reproduced video data starting from the position of the designated time code. This video data is sent to the second video processor 12 in the computer 2 as a video signal V3.

At the next step SP128, the time code is extracted from the video signal V3 in the second video processor 12, and image processing for converting the video signal V3 into digital component video data is performed. The converted video data is temporarily stored in the frame memory 12c in the second video processor 12. In the next step SP129, the reproduction video data stored in the frame memory 12c is reduced to 380 × 240 pixels, and
Transfer to M13b. In the next step SP130, the reproduced video data stored in the VRAM 13b is displayed on the reproduced video screen 23a. As a result, real-time video data starting from a position earlier by the key-up time than the in point designated by the operator is displayed on the reproduced video screen 23a.

At the next step SP131, the CPU 10
Judge whether or not marking has been performed. The determination as to whether or not the marking has been performed is determined by the playback video marking area 27.
Mark-in button 27c or mark-out button 27
This is performed based on whether or not the mouse 2d is clicked in a state where the cursor is located in the area f. as a result,
If the mark-in button 27c is clicked,
It is determined that the in-point has been designated and the process proceeds to step SP132. If the mark-out button 27f has been clicked, it is determined that the out-point has been designated and step SP1 has been performed.
Proceed to 35.

At step SP132, clip image data of the IN point is generated. The in-point clipped image data is generated by reading the video data stored in the frame memory 12c into the VRAM 13b. At this time, since the data amount is thinned out to 1/16 by reducing the number of read samples, clip image data having an image size of 95 pixels × 60 pixels is generated. In the next step SP133, the VRAM 13
The in-point clipped image data stored in b is read out and displayed in the clip display area 27a.
In the next step SP134, the clip image data of the IN point, which has been marked before and was displayed in the clip display area 27a, is moved to the clip display area 28. Note that this processing is not performed if the marking has not been previously made and the clip image data has not been displayed in the clip display area 27a. When the processing in step SP134 ends, the CPU 10 proceeds to step SP142.

On the other hand, when the process proceeds to step SP135 for marking the out point, the clip image data of the out point is generated here. The clip image data at the out point is also generated by reading the video data stored in the frame memory 12c into the VRAM 13b. Also in this case, clip image data of 95 pixels × 60 pixels is generated by thinning out the data amount to 1/16 at the time of reading. In step SP136, V
The out-point clip image data stored in the RAM 13b is read out, and the out-clip display area 27d is read out.
Will be displayed.

At the next step SP137, the CPU 10
Determines whether the previously marked clip image data is clip image data of the IN point. As a result, if the clipped image data marked earlier is the clipped image data at the IN point, step SP1 is executed.
The program proceeds to step SP139 if the previously marked clipped image data is the clipped image data at the out point. At step SP138, the CP
U10 determines whether or not to newly register as an event. This determination is made based on a click operation of the new event button 33 by the operator. If the new event button 33 is clicked and event registration is instructed, the process proceeds to step SP140. If the new event button 33 is not clicked and event registration is not instructed, the process proceeds to step SP139.

In step SP140, the CPU 10
The section from the in point to the out point is registered as an event. At this time, as shown in FIGS. 9 to 11, the second management record data relating to the event is generated. In the next step SP141, the generated clip image data of the in point of the event is copied to the event display area 29, and the clip image data is displayed in the event display area 29. When this process ends, the CPU 10 proceeds to the next step SP142.

On the other hand, if the processing proceeds to step SP139 because the clip image data generated by the previous marking is the clip image data of the out point, the processing proceeds to step SP139. The clip image data is moved to the clip display area 28. This processing is not performed if the marking has not been made first and the clip image data has not been displayed in the out-clip display area 27d. When the processing in step SP139 is completed, the CPU 10 proceeds to step S139.
Proceed to P142. In step SP142, the CPU 10
Determines whether the stop of the reproduction of the video data displayed on the reproduction video screen 23a has been instructed. As a result, if the reproduction stop is not instructed, step S
Returning to P131, the process is repeated, and when the reproduction stop is instructed, the process proceeds to the next step SP143. In step SP143, the CPU 10 issues a playback stop command to the hybrid recorder 3 via the external interface 18.
To send to. Thereby, the hybrid recorder 3 stops the read operation of the video data and stops the reproduction operation.
When the process of step SP143 ends, the CPU 1
In step SP144, the process proceeds to step SP144, and the preroll process ends.
