[Description of overall editing system configuration]
The overall configuration of the editing system will be described with reference to FIG. FIG. 1 conceptually shows the hardware configuration of the entire editing system.

The editing system includes a computer 1 and a hard disk array 2. The computer 1 is installed with an application program for editing video data sent to the computer. This application program installed on the editing computer is a program that can operate under the operating system of the computer. This application program includes a GUI (Graphical User Interface) for generating control commands.

The hard disk array 2, plural hard disks are connected in an array. The hard disk array 2 is apparently controlled so that recording and reproduction are performed simultaneously. In other words, the real-time video signal can be reproduced from the hard disk while the input real-time video signal is recorded.

  The computer 1 and the hard disk array 2 are connected by a communication cable based on the communication format of the RS-422 interface. The communication format of the RS-422 interface is a communication format that can simultaneously transmit / receive a video signal and a control command.

  The input video signal V1 input to the editing system is a composite video signal photographed by a video camera or the like, or a composite video signal transmitted from a VTR. This composite video signal is a signal transmitted in accordance with the SDI (serial digital interface) format. On the other hand, the video signal V2 or V3 output from the editing system is also a composite video signal transmitted according to the SDI format. Of course, the video signal input / output to / from the editing system may be a component video signal. Similarly, the video signal input / output to / from the editing system is not limited to a digital video signal but may be an analog composite video signal.

Further, by using the GUI displayed on the monitor of the computer 1, a control command for editing can be generated. The generated control command is transmitted to the hard disk array 2 as an RS-422 control command, and reproduction control of the hard disk array 2 is performed. The reproduced video signal V3 is displayed on the monitor of the computer 1 and sent to the outside.

[Description of Internal Configuration of Computer 1]
Next, the internal configuration of the computer 1 will be described in detail with reference to FIG. The computer 1 includes a system bus 5 for transmitting control signals and video signals, a CPU 10 for controlling the entire computer, a first video processor 11 and a second video processor 12 for performing image processing on the video signals, A display controller 13 for controlling graphic display for video signals and GUI displayed on the video monitor 14, an HDD interface 15 for controlling a local hard disk drive (local HDD) 15a, and a floppy (registered trademark) disk drive 16a. Control data is generated based on commands from a pointing device such as an FDD interface 16 for controlling, a cursor control device (generally called a mouse) 17a, a control panel 17b, and a keyboard 17c. In computing device interface 17 and includes an external interface unit 18 having a software driver for performing data communication based on the communication format of the hard disk array 2 and RS-422.

  The system bus 5 is used for communication of video data, command data, and address data in the computer 1, and includes an image data bus 5a for transmitting video data and a command data bus for transmitting control signals. 5b. The image data bus 5a is connected with the first and second video processors 11 and 12, the display controller 13, the HDD interface 15, and the FDD interface 16, respectively. Accordingly, the first video processor 11, the second video processor 12, the display controller 13, the HDD interface 15, and the FDD interface 16 are connected via the image data bus 5a, and video data is transmitted between the blocks. It can be performed. On the other hand, a CPU 10, a first video processor 11, a second video processor 12, a display controller 13, an HDD interface 15, an FDD interface 16, a pointing device interface 17 and an external interface unit 18 are connected to the command data bus 5b. Yes. That is, all the blocks inside the computer 1 are connected via the command data bus 5b. The CPU 10 is a block for controlling the entire computer. The CPU 10 includes a ROM 10a that stores the operating system of the computer 1 and a RAM 10b that uploads and stores application programs recorded on the hard disk 15a. When starting up the computer 1, the CPU 10 executes a software program based on the operating system stored in the ROM 10a. When the application is executed under this operating system, the CPU 10 reads the application program recorded on the hard disk of the hard disk drive 15a and uploads it to the RAM 10b.

  The first video processor 11 receives the first composite video signal V2 input to the computer 1, converts the data for the first composite video signal V2, and temporarily buffers the converted composite video signal. It is a block to do. Specifically, the first video processor 11 includes a processor controller 11a that controls the entire video processor 11, a data converter 11b that converts the received analog composite video signal into digital component video data, and data conversion A frame memory 11c that temporarily stores video data for several frames sent from the unit 11b.

  The processor controller 11a sends a control signal for data conversion to the data converter 11b and sends a control signal for extracting a time code from the composite video signal V2 input to the data converter 11b to the data converter 11b. . The processor controller 11a outputs a control signal for controlling the read / write timing and the read / write address of the frame memory 11c. Specifically, the processor controller 11a controls the read timing of the frame memory so that the time code sent to the display controller 13 corresponds to the video data (frame data).

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

  Next, how the time code is transmitted and extracted will be described. This composite video signal V2 is an analog composite video signal in which a time code is superimposed in the vertical synchronization period of the input video signal V1. This time code is a signal inserted into two lines of 14H and 16H or 12H and 14H in the vertical blanking period, and is called a so-called VITC (Vertical Interval Time Code). In this embodiment, a time code generated by a time code generator synchronized with an external on-air system is used as this time code. However, a time code generator is provided inside the hard disk array 2 and is generated by the internal generator. Time code may be used. In the present embodiment, the time code thus encoded is superimposed on the composite signal. When extracting the time code from the composite video signal, it is possible to easily extract the time code by decoding only the digitally converted time code in the vertical synchronization period when converting the analog signal to digital data. it can.

  In the frame memory 11c, video data converted into digital data is temporarily stored. The read / write timing of the frame memory 11c is controlled by the processor controller 11a. The frame memory 11c is composed of two frame memories (having a capacity of 1 Mbyte), and has a total capacity of 4 Mbytes. The video data stored in the frame memory 11c is video data composed of 1520 pixels × 960 pixels, and video data for two frames can be stored in the frame memory. 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 not video data of 1520 pixels × 960 pixels, that is, video data in which the amount of data is thinned out so as to be 380 pixels × 240 pixels. Here, thinning out the data amount simply means that the sampling rate for reading video data from the frame memory 11c is set to ¼ to reduce the read video data amount. The read video data of 380 pixels × 240 pixels is sent to the display controller 13 via the image data bus 5a.

  The second video processor 12 has the same configuration as that of the first video processor. That is, a processor controller 12a that controls the entire video processor 12, a data converter 12b that converts the received analog composite video signal into digital component video data, and a video for several frames sent from the data converter 12b. And a frame memory 12c for temporarily storing data.

It is.

  Since the composite video signal V2 is a video signal in which the time code is superimposed in the vertical synchronization period of the input video signal V1 in the hard disk array 2, it is the same video signal in time as the input video signal input in real time. That is, the video data stored in the frame memory 11c is the same video data as the video signal obtained by digitizing the input video signal.

  The composite video signal V3 is a video signal reproduced from the hard disk array in accordance with an instruction from the computer 1. Therefore, the composite video signal V3 is a video signal that is not temporally related to the input video signal V1. This will be described in detail below. When the operator instructs the computer 1 to reproduce desired video data, the computer 1 outputs a reproduction command to the hard disk array 2.

The data is transmitted to the display controller 13 as data.

  The display controller 13 is a control block for controlling data displayed on the monitor 14. The display controller 13 includes a memory controller 13a and a VRAM (Video Random Access Memory) 13b. The memory controller 13a controls the read / write timing of the VRAM 13b according to the internal synchronization inside the computer 1. In this VRAM 13b, the video data from the frame memory 11c of the first video processor 11, the video data from the frame memory 12c of the second video processor 12, and the image data from the CPU 10 are supplied with a timing control signal from the memory controller 13a. Is stored based on The image data stored in the VRAM 13b is read from the VRAM 13b by the timing control signal from the memory controller 13b based on the internal synchronization of the computer and is displayed on the video monitor 14 as a graphic. The graphic display displayed on the monitor 14 in this way 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 such as a window, a cursor, or a scroll bar. By displaying these plural types of image data on the monitor, a graphic display for GUI can be obtained.

  The clip number display portion 28d displays a clip number assigned to the clip image data displayed in the clip image data display area 28a. This clip number is a number automatically assigned to clip image data in the order in which the clip image data is marked.

  The forward button 28e and the return button 28f are used when the clip image data display in the clip display area 28 is advanced or returned backward. When a large number of clip image data is generated, all clip image data cannot be displayed on the monitor in the clip display area. At such time, all the clip image data can be displayed on the monitor by operating the forward button 28e and the return button 28f to advance or return the clip image data forward.

  The event display area 29 is provided in the clip image data of the event generated by sequentially clicking the mark IN button 24c and the mark OUT button 24f provided in the recording video marking area 24, and the reproduction video marking area 27. This is an area for displaying clip image data of an event marked by clicking the mark IN button 27c and the mark OUT button 27f in order. For one event, clip image data of either the in-point clip image data or the out-point clip image data is displayed. Similar to the clip display area 28, the event display area 29 includes a clip image data display area 29a, a time code display unit 29b, a clip type display unit 29c, an event number display unit 29d, a forward button 29e, and a return button. 29f and an event title display section 29g.

  The clip type display unit 29c displays data indicating whether the clip image data of the event displayed in the clip image data display area 29a is the In point or the Out point. When IN-point clip image data is displayed as the clip image data of the event, the characters “IN” are displayed in the clip type display portion. If it is desired to display out-point clip image data instead of in-point clip image data, clicking this clip type display portion 29c displays out-point clip image data. Thereafter, each time the clip type display portion 29c is clicked, the display of the IN point clip image data and the OUT point clip image data is switched.

  In the event number display section 29d, an event number assigned to the generated event is displayed. The event number is a number automatically assigned to the event in the order in which the event is generated, and is a number that has nothing to do with the clip number.

  In the event title display portion 29g, the title attached to the event is displayed as a character.

  In the program display area 30, a copy of the clip image data of the event displayed in the event display area 29 is displayed. By dragging the clip image data of the event displayed in the event display area 29 and copying it to the program display area 30, the events displayed in the event display area 29 can be rearranged freely. When rearranging the clip image data in the program display area 30, the clip image data of the event displayed in the program display area 30 is dragged and is moved again to another place in the program display area 30. By moving, events can be rearranged freely. In this case, the event is moved, not copied. Similar to the event display area 29, the program display area 30 is a clip image data display area 30a, a time code display section 30b, a clip type display section 30c, an event number display section 30d, a forward button 30e, and a return button. 30f and an event title display section 30g.

  The recording start button 31 a and the recording end button 31 b are buttons for sending control commands for recording start and recording end to the hard disk array 2. When the recording start button 31a is clicked, the CPU 10 grasps that the recording start button 31a has been pressed and instructs the external interface 18 to output a recording start command. The external interface 18 converts a command from the CPU 10 into a recording start command (REC START command) defined by the RS 422 and sends it to the hard disk array 2. The hard disk array 2 starts recording the input video signal V1 on the hard disk in response to the received recording start command. When the recording end button 31b is clicked, the CPU 10 detects that the recording end button 31b has been pressed, and instructs the external interface 18 to output a recording end command. The external interface 18 converts a command from the CPU 10 into a recording end command (REC STOP command) defined by RS-422 and sends it to the hard disk array 2. In response to the received recording end command, the hard disk array 2 ends the recording of the input video signal V1 on the hard disk.

  The preview button 32 is used when previewing a selected event or program. When an event or program is designated, clip image data of the designated event or program is displayed on the playback video screen 23a in a still picture (STILL) state. At this time, when the preview button 32 is clicked, the CPU 10 detects that the preview button has been pressed, and instructs the external interface 18 to output a reproduction start command. The external interface 18 converts a command from the CPU 10 into a playback start command (PLAY START command) defined by RS-422 and sends it to the hard disk array 2. In response to the received playback start command, the hard disk array 2 starts playback of the composite video signal V3 from the hard disk.

  The new event button 33 is used when creating a new event. The new event button 33 is clicked when an event in which the in point and the out point are changed with respect to the event designated by the operator is registered as another new event.

The replace button 34 is used when it is desired to change the In point and Out point of the selected event. For the specified event by Opereta, an event that in-point and out-point has been changed, rather than another new event, click this replace button 3 4 when replacing a the specified event.

  The delete button 35 is used to delete a selected event or program. The deleted event or program is discarded in the recycle box 26.

[Description of Clip Image Data Management Method]
Next, a method for storing clip data, event data, and program data will be described. Here, the clip data includes data for displaying the clip image data in the clip display area 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 first management record data is provided for each of clip data, event data, and program data. That is, the first management record data for clip data is data for managing all clip image data displayed in the clip display area 28. 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 program data is data for managing all clip image data displayed in the program display area 30. In this embodiment, the first management record data has only one first management record data for clip data, event data, and program data.

  The first management record data includes a pointer to previously linked data, a pointer to linked data, a display horizontal size for one page, a display vertical size for one page, a screen It has data on the upper display position, the display head position, and the total number of links.

  The pointer to the data linked before is data for 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 recorded.

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

  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 display area of the clip display area 28, the event display area 29, and the program display area 30. In this embodiment, since 11 clip image data can be displayed in each of the clip display area 28, the event display area 29, and the program display area 30, "11" is indicated as the display horizontal size for one page. Data is recorded in each 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 display area of the clip display area 28, the event display area 29, and the program display area 30. In this embodiment, since only one clip image data can be displayed in both the clip display area 28, the event display area 29, and the program display area 30, data indicating “one” as the display vertical size for one page is displayed. It is recorded in 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, on the screen, a clip display area 28 is provided in the lower stage, an event display area 29 is provided in the middle stage, and a program display area 30 is provided in the upper stage. Therefore, if it is the first management record data for clip data, data indicating “lower” is recorded as data indicating the display position on the screen, and if it is the first management record data for event data, the screen Data indicating “middle stage” is recorded as data indicating the upper display position. If the first management record data is for program data, data indicating “upper stage” is recorded as data indicating the display position on the screen. The

The Viewing head position, the clip display area 28, in each display area of the event display area 29 and the program display area 30, a data for indicating whether the display of the clip image data is started from which position. In the present embodiment, 11 clip image data in the clip display area 28, 11 clip image data in the event display area 29, and 11 clip image data in the program display area 30 can be displayed. Clip image data can be displayed. The display positions are managed by assigning numbers to the 33 display positions in order from the top on the screen. For example, the display position of the program display area 30 is the display position of the numbers 1 to 11, the display position of the event display area 29 is the display position of the numbers 12 to 22, and the display position of the clip display area 28 is the display position of the numbers 23 to 33. It is decided so. Therefore, if it is the first management record data for clip data, data indicating “23” is recorded as data indicating the display head position, and if it is the first management record data for event data, the display head position is displayed. As data indicating “12”, data indicating “12” is recorded, and in the case of the first management record data for program data, data indicating “1” is recorded as data indicating the display head position.

  The total number of links is data indicating how many management record data are 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 clip data is data for managing the clip image data displayed in the clip display area 28 for each clip image data. Therefore, the same number 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 linked data, an attribute, a clip image data handle, a clip type, and a time code. Data and an index number of clip image data.

  The pointer to previously linked data is data indicating a pointer of management record data linked before the second management record data. Since the first management record data or the second management record data always exists in the second management record data, the pointer of the data linked before is always recorded.

  The pointer to data linked later is data indicating a pointer of management record data linked after the second management record data. If there is no management record data linked later, its own pointer is recorded.

  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 where the clip image data is recorded. Therefore, the address where the clip image data is stored can be obtained by referring to the clip image data handle in the second management record data corresponding to the desired clip image data.

  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 clip image data is an index number assigned to clip image data. This index number is a number that is sequentially assigned to all marked clip image data regardless of the generation of the IN point, OUT point, and event. That is, it is the same number as the clip number displayed in the clip number table portion 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 data for managing the clip image data displayed in the event display area 29 for each clip image data. Therefore, the same number of second management record data for event data as the number of clip image data displayed in the event display area 29 exists. 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 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 linked data, an attribute, an event number, a title, and a subtitle. In-point clip image data handle, In-point clip type, In-point timecode data, In-point clip image data index number, Out-point clip image data handle, Out-point clip It has a type, out-point time code data, out-point clip image data index number, slow type, symbol type, and symbol time code data.

  Since the pointer to the data linked before, the pointer to the data linked later and the attribute are the same as those of the second management record data for clip data described above, description thereof will be omitted.

  The event number is a number assigned to the event in the order of generation. This event number is displayed in the event number display part 29d.

  A title and a subtitle are a title and a subtitle given in advance to a registered event, and are stored as actual characters. The title is displayed on the title display section 29g.

  The in-point clip image data handle is data indicating an address where the in-point clip image data is recorded. Therefore, the address at which the In-point clip image data is stored can be obtained 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. it can.

  The In-point clip type is data indicating whether the In-point clip image data managed by the second management record data is In-point clip image data or Out-point clip image data. It is. Here, data indicating all in-point clip image data is stored.

  The in-point time code data is data indicating the time code of the in-point clip image data managed by the second management record data.

  The index number of the IN-point clip image data is an index number assigned to the IN-point clip 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 the in point is marked regardless of the generation of the in point, the out point, and the event. It is a number assigned to all clip image data in order.

  The out-point clip image data handle is data indicating an address where the out-point clip image data is recorded. Therefore, by referring to the clip image data handle of the out point corresponding to the second management record data corresponding to the clip image data of the desired out point, the address where the clip image data of the desired out point is stored is obtained. be able to.

  The out-point clip type is data indicating whether the out-point clip image data managed by the second management record data is in-clip image data or out-point clip image data. is there. Here, data indicating all out-point clipped image data is stored.

  The out-point time code data is data indicating the time code of the out-point clip image data managed by the second management record data.

  The index number of the out-point clip image data is an index number assigned to the out-point clip 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 of the out point is marked regardless of the generation of the in point, the out point, and the event. It is a number assigned to all clip image data in order.

  The slow type is data indicating whether the event or program managed by the second management record data is set to playback speed control using the playback speed setting area 25 or normal playback control. .

  The symbol type is data indicating whether or not clip image data defined as a symbol exists in the period of the In point and the Out point of the event managed by the second management record data. The symbol means representative clip image data for representing the event.

  The symbol time code data is a time code of clip image data set as a symbol.

  Next, how the clip image data is managed using the first management record data and the second management record data described above will be described with an example.

  With reference to FIGS. 7, 8, 9A, 9B, and 9C, a method for managing clip image data will be described in detail.

  The “marking” row shown in FIG. 7 indicates whether the marking is performed with IN or OUT. In this example, it means that marking is performed 15 times in order from the left: IN, IN, OUT, IN, OUT, IN, IN, IN, OUT, IN, OUT, IN, IN, IN, IN. In the row of “INDEX No.”, index numbers assigned to the clipped image data of the marked in and out points are shown. This index number is a number assigned to all the clipped image data marked in order without regard to the IN point and OUT point. Therefore, as shown in FIG. 7, index numbers 1 to 15 are sequentially assigned to the marked clip image data. In the row of “Clip No.”, the clip number displayed in the clip number display area 28d of the clip display area 28 is shown. The clip number displayed in the clip number display area 28d is the same number as the index number. In the “Event No.” line, an event number displayed in the event number display area 29 d of the event display area 29 is shown. 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. 8 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, clip image data with index number 1, clip image data with index number 6, clip image data with index number 7, clip image data with index number 12, clip image data with index number 13, index number 14 The clip image data are displayed in order.

  In the event display area 29, the four created events are displayed. Clip image data with index number 2 is displayed as an event with event number 1, clip image data with index number 4 is displayed as an event with event number 2, and clip image data with index number 8 is displayed as an event with event number 3. The clip image data of index number 10 is displayed in order as the event of event number 4.

  In the program display area 30, clip image data is not displayed only by specifying the IN point and OUT point. In this example, it is assumed that a program as shown in FIG. 8 is created by exchanging four events displayed in the event display area 29. The program is a program that is serialized in the order of event number 2 event, event number 4 event, and event number 1 event. Accordingly, in the program display area 30, the clip image data with index number 4 registered as the event with event number 2, the clip image data with index number 10 registered as the event with event number 4, and the event with event number 1 are registered. The clip image data with the index number 2 is displayed.

  9A, 9B, and 9C are diagrams showing how clip image data is managed by the first management record data and the second management record data.

  FIG. 9C shows how clip image data displayed in the clip display area 28 is managed. The management record data 101 is first management record data for clips. As shown in FIG. 4, the first management record data 101 for the clip includes data for managing the entire area of the clip display area 28 and the position of the clip image data displayed in the clip display area. Have.

  Management record data 201 linked after the first management record data 101 is second management record data for clips. The second management record data 201 is data for managing clip image data with index number 1. As shown in FIG. 5, the second management record data 201 has a clip image data handle for indicating an address where the clip image data with index number 1 is stored.

  Management record data 206 linked after the second management record data 201 is second management record data for clips. The second management record data 206 is data for managing the clip image data with the index number 6, and has a clip image data handle for indicating the address where the clip image data with the index number 6 is stored. is doing.

  Similarly, the second management record data 206 is linked with the second management record data 207 for managing the clip image data with the index number 7, and the second management record data 207 is followed by the index number. The second management record data 212 for managing the clip image data of 12 is linked, and after the second management record data 212, the second management record data for managing the clip image data of the index number 13 213 are linked, and second management record data 214 for managing clip image data of index number 14 is linked after the second management record data 213.

FIG. 9B shows how clip image data displayed in the event display area 29 is managed. The management record data 102 is first management record data for events. As shown in FIG. 4, the first management record data 102 includes 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. ing.

  Management record data 202 linked after the first management record data 102 is second management record data for an event. As shown in FIG. 6, the second management record data 202 is used to manage in-point clip image data indicated by index number 2 and out-point clip image data indicated by index number 3. I have data. Specifically, the second management record data 202 includes an in-point clip image data handle indicating the address of the in-point clip image data indicated by index number 2 and an out-point clip indicated by index number 3. It has an out-point clipped image data handle indicating the address of the image data.

  Similarly, after the second management record data 202, the second management record data 204 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 linked. After the second management record data 204, the second management record data 208 for managing the clip image data of the In point with the index number 8 and the clip image data of the Out point with the index number 9 is linked. After the management record data 208 of the second index, the second management record data 210 for managing the clip image data of the IN point of the index number 10 and the clip image data of the OUT point of the index number 11 is linked.

  FIG. 9A shows how clip image data displayed in the program display area 30 is managed. Management record data 103 is first management record data for a program. As shown in FIG. 4, the first management record data 103 includes data for managing the entire area of the program display area 30 and the position of clip image data displayed in the program display area 29. ing.

  After the first management record data 103 for the program, the second management record data 204 for managing the clip image data at the index number 4 and the clip image data at the index number 5 is linked. The second management record data 204 is linked with the second management record data 210 for managing the clip image data at the index number 10 and the clip image data at the index number 11 after the second management record data 204. After the management record data 210 of 2, the second management record data 208 for managing the in-point clip image data of index number 2 and the out-point clip image data of index number 3 is linked.

  Here, FIG. 9B showing management of event data is compared with FIG. 9A showing management of program data. The order of storing the clip image data of index number 2, the clip image data of index number 4, and the clip image data of index number 10 is not changed at all between FIGS. 9A and 9B. That is, this means that the storage position of the clip image data is not changed at all. A difference between FIG. 9A and FIG. 9B is that the link order of the second management record data is changed. In other words, according to the present invention, in order to change the display order of events, the storage order of clip image data representing events is not changed, but the link order of second management record data that directly manages clip image data. To change. Therefore, the display order of events can be changed at high speed.

  The same applies to the change in the display order of the clip image data displayed in the clip display area 28 as well as the change in the display order of the events. For example, even if the display order of clip image data is changed by deleting or newly adding clip image data, it is not necessary to actually move the storage position of the clip image data, and the second management record data You only need to change the link information.

  Next, the first marking to the 15th marking will be described in order.

  First, before starting the marking, the first management record data 101 for clip data and the first management record data for event data are already included in the start address of the area for storing work data in the RAM 10b. 102 and first management record data 103 for program data are generated. However, since there is no second management record data to which any management record data is linked, its own address is stored in “pointer to data linked later”.

a) First marking (In point)
When the first marking is performed, clip image data of 95 pixels × 60 pixels is formed by controlling reading from the frame memory 11e. The formed clip image data is stored in the empty area of the RAM 10b as clip image data of index number 1. Simultaneously with this storage, the formed clip image data is displayed in the in-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 and is not stored in the RAM 10b. This is because at this time, it is unclear to which management record data the second management record data 201 is linked.

b) Second marking (In point)
When the second marking is performed, similarly, the clip image data with the index number 2 is formed and stored in the empty area of the RAM 10b. At this time, since the IN point has been marked twice in succession, the clip image data with index number 1 displayed in the in clip display area 24a is not used as an event. Accordingly, the clip image data with the index number 1 displayed in the in-clip display area 24 a is moved to the clip display area 28. Also, by this second marking, it is determined that the second management record data for managing the clip image data of index number 1 is linked to the first management record data 101 for clip data. Therefore, as shown in FIG. 9C, the second management record data 201 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 101.

  On the other hand, the clip image data with the index number 2 generated by the second marking is newly displayed in the in-clip display area 24a. Similar to the first marking, the second management record data 202 for managing the clip image data of index number 2 is temporarily newly stored in a register in the CPU 10.

c) 3rd marking (out point)
When the third marking is performed, the clip image data with the index number 3 is similarly formed and stored in the empty area of the RAM 10b. Since this third marking is an out point, an event is formed in which the clip image data with index number 2 is the in point and the clip image data with index number 3 is the out point. Accordingly, the clip image data of index number 2 displayed in the in-clip display area 24a is copied to the event display area 28 while being displayed in the in-clip display area 24a. Further, by this third marking, the second management record data 202 for managing the clip image data with the index number 2 stored in the register is linked to the first management record data 102 for event data. It is determined. Therefore, as shown in FIG. 9B, the second management record data 202 temporarily stored in the register of the CPU 10 is stored in the RAM 10 b so as to be linked to the first management record data 102.

  On the other hand, the clip image data with the index number 3 generated by the third marking is newly displayed in the out clip display area 24d. Since the second management record data 202 for managing the clip image data with the index number 3 is determined to be linked to the first management record data 102, it is temporarily stored in a register in the CPU 10. It will never be remembered.

d) Fourth marking (in point)
When the fourth marking is performed, similarly, clip image data with index number 4 is formed and stored in the empty area of the RAM 10b. Simultaneously with this storage, the formed clip image data is displayed in the in-clip display area 24a. Similarly to the first marking, the second management record data 204 for managing the clip image data with the index number 4 is temporarily stored in a register in the CPU 10. Note that the clip image data with the index number 3 displayed in the out clip display area 24d has already been recorded, and is thus cleared from the display area 24d.

e) 5th marking (out point)
When the fifth marking is performed, the clip image data with the index number 5 is similarly formed and stored in the empty area of the RAM 10b. Similar to the third marking, since the fifth marking is an out point, an event is formed with the clip image data with index number 4 as the in point and the clip image data with index number 5 as the out point. Accordingly, the clip image data with the index number 4 displayed in the in-clip display area 24a is copied to the event display area 29 while being displayed in the in-clip display area 24a. Also, by this fifth marking, it is determined that the second management record data 204 for managing the clip image data with the index number 4 stored in the register is linked to the second management record data 202 stored previously. Is done. Therefore, as shown in FIG. 9B, the second management record data 204 temporarily stored in the register of the CPU 10 is stored in the RAM 10 b so as to be linked to the second management record data 202.

  On the other hand, the clip image data with the index number 5 generated by the fifth marking is newly displayed in the out clip display area 24d. Since the second management record data 204 for managing the clip image data with the index number 5 is determined to be linked to the second management record data 202, it is temporarily stored in a register in the CPU 10. It will never be remembered.

f) 6th marking (In point)
When the sixth marking is performed, similarly, clip image data of index number 6 is formed and stored in an empty area of the RAM 10b. Simultaneously with this storage, the formed clip image data with index number 6 is displayed in the in-clip display area 24a. Similarly to the fourth marking, the second management record data 206 for managing the clip image data with the index number 6 is temporarily stored in a register in the CPU 10. Note that the clip image data with the index number 5 displayed in the out clip display area 24d has already been recorded, and is thus cleared from the display area 24d.

g) 7th marking (In point)
When the seventh marking is performed, similarly, clip image data of index number 7 is formed and stored in an empty area of the RAM 10b. Since the IN point is marked twice in succession, the clip image data of index number 6 displayed in the in clip display area 24 a is moved to the clip display area 28. Further, by the seventh marking, the second management record data 206 stored in the register of the CPU 10 is stored in the RAM 10b so as to be linked to the second management record data 201 as shown in FIG. 9C. Remembered. On the other hand, the formed clip image data of index number 7 is displayed in the in-clip display area 24a. Similarly to the sixth marking, the second management record data 207 for managing the clip image data with the index number 7 is temporarily stored in a register in the CPU 10.

Hereinafter, the 9th to 15th markings are performed in the same manner as the 1st to 7th markings, and thus the description thereof is omitted.

[Description of hard disk array 2]
Next, the hard disk array 2 will be described with reference to FIG. FIG. 10 shows the overall configuration of the hard disk array 2.

The CPU 70a is a central processing circuit for controlling all blocks of the hard disk array 2. CPU70a receives a control command based on the communication protocol of RS-422 which is externally supplied to the system controller, according to the command, DMA controller 70c, 70 e, and, SCSI controllers 70d, controls the 70f. Further, the CPU 70a receives the time code from the time code generator 70b or the external time code (Ext. TC) supplied from the outside to the system controller 70, and uses the received time code data as the video data input / output unit 71 and the audio data. This is supplied to the input / output unit 74. Furthermore, it has an internal RAM that stores all the video data recording addresses stored in the video hard disk 73 in units of frames and all the time codes of the recorded frames in association with each other. Similarly, all recording addresses of audio data stored in units of frames in the audio hard disk 76 are associated with all time codes of recorded frames and stored in the same RAM. Therefore, video data and audio data can be easily reproduced from the hard disk simply by specifying the time code from the outside.

  The DMA controller 70c controls the read timing when reading the video data from the buffer memories 72b and 72e provided in the video data processing unit 72 according to the command from the CPU 70a, and writes the video data to the buffer memories 72b and 72e. Control the write timing.

  The SCSI controller 70d converts the control command from the CPU 70a, the video data in frame units received from the DMA controller 70c, and the time code data associated with the frame video data into SCSI communication commands, and a hard disk for video data 73. The video data reproduced from the hard disk 73 is converted from the SCSI communication command and supplied to the DMA controller 70c.

  The DMA controller 70e controls read timing when audio data is read from the buffer memories 75b and 75d provided in the audio data processing unit 75 in accordance with a command from the CPU 70a, and writes the audio data to the buffer memories 75b and 75d. Control the write timing.

Also, the audio data reproduced from the hard disk 76 is converted from the SCSI command and supplied to the DMA controller 70e.

  The input system of the video data input / output unit 71 extracts a synchronizing signal of the input video signal V1, and also converts a decoder 71a that converts the input video signal V1 into a component signal, and an A / A that converts an analog component video signal into a digital video signal. D conversion circuit 71b. The output system of the video data input / output unit 71 includes a D / A conversion circuit 71d for converting the reproduced video signal of the first channel supplied from the video data processing unit 72 into analog, and the reproduced video signal of the first channel as a composite signal. Encoder 71c which converts the output composite video signal to a vertical synchronization signal on which the time code is superimposed based on the phase of the external synchronization signal (Ext. Sync) supplied to the system controller 70. A D / A conversion circuit 71f that converts the second channel playback video signal supplied from the video data processing unit 72 into analog, and converts the second channel playback video signal into a composite signal and outputs the composite The video signal is externally supplied to the system controller 70. Based on the phase of the signal (EXT.SYNC), composed of an encoder 71e to impart vertical synchronizing signal time code is superimposed.

  The input system of the video data processing unit 72 includes a compression unit 72a that compresses the video data supplied from the video data input / output unit 71 in units of frames based on the JPEG standard, and a write command from the DMA controller 70c. A buffer memory 72b that stores video data from the compression unit 72a and supplies the compressed video data to the expansion unit 72c or the DMA controller 70c based on a write command from the DMA controller 70c. The output system of the video data processing unit 72 receives the compressed video data from the buffer memory 72b, decompresses the compressed video data, and outputs the compressed video data as the first channel video data, and the compressed video data from the buffer memory 72e. And a decompression unit 72d for decompressing the compressed video data and outputting it as video data of the second channel. The video processing unit 72 includes a buffer memory 72b that stores video data for the first channel and a buffer memory 72e that stores video data for the second channel. The buffer memories 72b and 72e are composed of a FIFO memory and have a capacity capable of storing video data for 15 frames.

  Similarly to the video data input / output unit 71, the audio data input / output unit 74 includes a decoder 74a that converts the input audio signal A1, an A / D conversion circuit 74b that converts an analog audio signal into digital audio data, and audio data processing. A D / A conversion circuit 74d for converting the reproduced audio data supplied from the unit 75 into analog; and an encoder 74c for converting the analog audio signal supplied from the D / A conversion circuit 74d into the audio signal A2. .

  The audio data processing unit 75 compresses the audio data supplied from the audio data input / output unit 74 and stores the audio data from the compression unit 75a based on the control command from the DMA controller 70e. A buffer memory 75b for supplying compressed audio data to the DMA controller 70e, a buffer memory 75d for receiving audio data reproduced from the DMA controller 70e and outputting it to the decompressing unit 75c, and receiving reproduced audio data from the buffer memory 75d for receiving compressed audio It has a decompression length 75c for decompressing data.

  Next, recording and reproduction operations of the hard disk array will be described.

  The video signal supplied to the video data input / output unit 71 is subjected to predetermined input / output processing and supplied to the video data processing unit 72. The video data compressed by the compression unit 72a of the video data processing unit 72 is supplied to the buffer memory 72b. The video data supplied to the buffer memory 72b is sent to both the DMA controller 70c and the decompression circuit 72c in response to a read command from the DMA controller 70c. The CPU 70a sends a recording address to the SCSI controller 70d so as to associate the time code data supplied from the time code generator 70b with the video data supplied to the DMA controller 70c. The SCSI controller 70d supplies a recording command and video data to the hard disk 73 so as to record the video data received from the DMA controller 70c at an address designated by the CPU 70a.

  On the other hand, the video data supplied to the decompression circuit 72 c is decompressed as video data of the first channel and sent to the video data input / output unit 71. The video data input / output unit 71 superimposes the time code supplied from the CPU 70a on the vertical synchronization period of the supplied video data and sends it as a composite video signal V2.

  Next, playback processing of the hard disk array 2 will be described.

  When a reproduction command according to the RS-422 communication protocol is sent to the hard disk array 2, the CPU 70a outputs the reproduction command to the hard disk 73 via the SCSI controller 70d. The reproduced video data is stored in the buffer memory 72e in accordance with the write timing of the DMA controller 70c. The video data read from the buffer memory 72e is decompressed as video data of the second channel by the decompression circuit 72d and sent to the video data input / output unit 71. The video data input / output unit 71 superimposes the time code supplied from the CPU 70a on the vertical synchronization period of the supplied video data and sends it as a composite video signal V3.

  Here, the reason why the recording process of the input video signal V1 and the reproduction process of the video signal V3 can be performed simultaneously will be described. While the DMA controller 70c outputs a read command to the buffer memory 72b, a video signal is recorded from the buffer memory 72b to the hard disk 73, and the DMA controller 70c writes a write command to the buffer memory 72e. Is output, the video signal recorded by the hard disk 73 is reproduced, and the reproduced video data is supplied to the buffer memory 72e. That is, transfer of recorded video data to the hard disk 73 is buffered by the buffer memory 72b, and transfer of video data reproduced from the hard disk 73 to the video data input / output unit 71 is buffered by the buffer memory 72e. Apparently, it seems that the recording process of the input video signal V1 and the reproduction process of the video signal V3 are performed simultaneously. Strictly speaking, since the recording operation and the reproducing operation of the hard disk 73 are performed alternately, the recording operation and the reproducing operation are not simultaneous.

[Description of computer operation]
The initial operation of the computer 1 will be described with reference to FIG.

  First, in step SP1, it starts when an operator designates execution of an application program.

  In step SP2, since this application program is stored in the local hard disk 15a, the CPU 10 uploads the application program to the operation RAM 10b provided in the CPU 10.

  When uploading to the RAM 10b in the CPU 10 is completed in step SP3, the CPU 10 executes the application program.

  In step SP4, a memory area of the RAM 10b is secured. The reason for securing this memory area is to store each piece of data in the RAM 10b since a plurality of clip image data and editing data are generated by the editing operation. In step SP4, the first management record data for clip data, event data, and program data shown in FIGS. 9C, 9B, and 9A is recorded in the RAM 10b.

  In step SP5, a work folder for storing a program, event data and the like generated by the editing operation by the computer 1 is generated. The generated work holder is recorded on the local hard disk 15a.

  In step SP6, in order to display a graphic display for GUI on the monitor 14, the CPU 10 transfers the graphic data to the VRAM 13b in real time in synchronization with the internal clock of the computer.

  In step SP7, the same graphic as the graphic data stored in the VRAM 13b is displayed on the monitor 14.

  In step SP8, it is confirmed whether or not the input video signal V2 is displayed on the recording video screen 21a. If there is no designation of video display, it is determined that no editing operation is performed, the process proceeds to step SP16, and the process ends. In the normal case, since the input video signal V2 needs to be displayed on the recording video screen 21a in order to perform the editing operation, the process proceeds to step SP9.

  In step SP9, an RS-422 control command is output to the hard disk array 2 so that the video signal V2 is output to the computer 1. When the hard disk array 2 receives a control command from the computer 1, the hard disk array 2 generates a video signal V 2 as a video signal for the first channel from the input video signal V 1 and sends it to the computer 1.

In step SP10, the data converter 11b extracts a time code from the composite video signal V2 supplied to the computer 1, and converts the input composite video signal into digital component video data. Converted video data is temporarily stored in the frame memory 11 c in frame units. The processor controller 11a sends the time code data extracted by the data converter 11b to the CPU 10.

In step SP11, the video data stored in the frame memory 11c is transferred to the VRAM 13b. The video data to be transferred is video data of 380 pixels × 240 pixels because there is little sampling from the frame memory 11c. The data to be transferred this time, in this VRAM13b is not only video data from the frame memory 11c, the video data from the frame memory 11 c is transferred in the area where the video data is displayed, the graphics for the GUI In the area where is displayed, the image data bus 5a is arbitrated so that the image data is transferred from the CPU 10. Further, the data stored in the VRAM 13b is updated in real time, whereby the video data can be displayed on the monitor 14 in real time.

  In step SP12, graphic data and video data stored in the VRAM 13b are displayed on the monitor 14 in real time.

  In step SP13, it is determined whether or not the hard disk array 2 starts recording the video data displayed on the recording video screen 21a. In order to start recording, the “START” button 31a is clicked.

  In step SP14, when the start of recording is designated, the CPU 10 sends the command to the external interface 18. The external interface 18 converts the communication format to the RS-422 standard and sends it to the hard disk array 2.

  In step SP15, since the recording is started by the hard disk array 2, it is determined that all the initial settings have been completed, and this flow is ended.

[Description of first marking operation]
Next, the marking operation will be described in detail with reference to FIG. Note that the flow shown in FIG. 12 all explains the operation of the CPU 10. Further, this marking operation can be better understood with reference to the description of FIGS.

  When the flow shown in FIG. 11 ends, it is determined that this marking operation can be performed, and step SP20 is started.

  In step SP21, it is determined whether or not a new marking has been performed. Whether or not marking has been performed is determined by whether or not the mouse is clicked when the cursor is positioned in the area of the mark-in button 24c or the mark-out button 24f. This determination is based on an interrupt command supplied to the CPU 10. If the mark-in button 24c is clicked, it is determined that an IN point has been designated, and the process proceeds to step SP22. If the markout button 24f is clicked, it is determined that an out point has been designated, and the process proceeds to step SP30.

  In step SP22, IN-point clip image data is formed. This IN-point clip image data is data formed when the video data stored in the frame memory 11c is read out to the VRAM 13b, and is 1/16 of the video data recorded in the frame memory 11c. Sampling rate is reduced to be a quantity. The clip image data is composed of 95 pixels × 60 pixels.

  In step SP23, the clip image data stored at the position of the in-clip display area 24a of the VRAM 13b is displayed in the in-clip display area 24a according to the data read from the VRAM 13b.

  In step SP24, it is determined whether or not the IN-point clip image data marked in step SP21 is the first marking. If it is the first marking, the process returns to step SP21. If it is the second or more marking, the process proceeds to step SP25.

  In step SP25, it is determined whether or not the previously marked clip image data is IN-point clip image data. If the previously marked clip image data is in-point clip image data, the process proceeds to step SP26. If the previously marked clip image data is out-point clip image data, the process proceeds to step SP27. move on.

  In step SP26, the in-point clip image data marked earlier is moved from the in-clip display area 24a to the clip display area 28. That is, in this case, it means that the IN point is continuously marked twice. For the second management record data formed at this time, it is preferable to refer to the description of FIGS.

  In step SP27, it is determined whether or not an event has been generated based on the previously marked out point. If an event has been generated by the previous marking, the process proceeds to step SP29. If an event has not been generated by the previous marking, the process proceeds to step SP28.

  In step SP28, the clip image data of the out point marked first and displayed in the out clip display area 24d is moved to the clip display area 28. This is because the previously marked out point is determined to be clip image data that is not used to generate an event.

  In step SP29, the clip image data displayed in the out clip display area 24d is cleared. Since the clip image data displayed in the out clip display area 24d is already registered as the out point of the event, it is not necessary to move to the clip display area 28.

  Returning to step SP21, the case where the out point is marked in step SP21 will be described. When the out point is designated, the process proceeds to step SP30.

  In step SP30, out-point clipped image data is formed. The out-point clipped image data is data formed when the video data stored in the frame memory 11c is read into the VRAM 13b, and is 1/16 of the video data recorded in the frame memory 11c. Sampling rate is reduced to be a quantity. The clip image data is composed of 95 pixels × 60 pixels.

  In step SP31, the clip image data stored at the position of the out clip display area 24d of the VRAM 13b is displayed in the out clip display area 24d according to the reading of the data from the VRAM 13b.

  In step SP32, it is determined whether or not the clip image data of the out point marked in step SP21 is the first marking. If it is the first marking, the process returns to step SP21. If it is the second or more marking, the process proceeds to step SP33.

  In step SP33, it is determined whether or not the previously marked clip image data is IN-point clip image data. If the previously marked clip image data is in-point clip image data, the process proceeds to step SP34. If the previously marked clip image data is out-point clip image data, the process proceeds to step SP36. move on.

  In step SP34, an event is registered. In this way, when the OUT point is marked after the IN point, it is automatically registered as an event. The description of the second management record data created for event registration can be better understood with reference to the description of FIGS.

  In step SP35, the clip image data of the in-point of the generated event is copied to the event display area 29.

  Step SP36, step SP37, and step SP38 are the same as step SP27, step SP28, and step SP29, and thus description thereof is omitted.

  In step SP39, it is determined whether or not to end marking. Until the marking is completed, the flow shown in FIG. 12 is repeated.

[Explanation of second marking operation]
13A and 13B show a flow when an event is created from a video signal reproduced from the hard disk array 2.

  This flow starts from a state where clip image data is already stored.

  In step SP41, it is determined whether or not clip image data has been designated. The clip image data is designated when the mouse is double-clicked (clicked twice in succession) while the cursor is in the display position of the clip image data.

  In step SP42, when clip image data is specified, if the specified clip image data is in-point clip image data, the in-clip display area 27a is used, and if it is out-point clip image data, the out-clip display area 27d is specified. Is displayed.

  In step SP43, the CPU 10 refers to the time code of the designated clip image data, and outputs a control command to the external interface 18 so as to perform still reproduction of the video data of the time code. The external interface 18 converts the still playback command into the RS-422 protocol and sends it to the hard disk array 2. The hard disk array 2 refers to the received data related to the time code and the storage address of the video data, and the video data that is still reproduced from the hard disk 73 is transmitted as the video data of the second channel.

  In step SP44, the video data sent from the hard disk array 2 is received, and predetermined image processing is performed in the second video processor 12.

  In step SP45, the still playback video data stored in the frame memory 12c is transferred to the VRAM 13b so as to be 380 pixels × 240 pixels.

  In step SP46, the reproduced video data stored in the VRAM 13b is displayed on the reproduced video screen 23a. Since the hard disk array 2 is still video data, not a real-time video signal, only a still image is displayed on the playback video screen 23a.

  Next, in step SP47, it is determined whether or not playback is designated for the still video data displayed on the playback video screen 23a. When the “PREVIEW” button 32 is clicked with the still video data displayed on the playback video screen 23a, it is determined that the playback operation is started.

  In step SP48, a reproduction start command is output to the hard disk array 2 via the external interface 18. The hard disk array 2 receives the playback start command and sends normal playback video data to the computer 1.

  In step SP51, it is determined whether or not marking has been performed. Whether or not marking has been performed is determined by whether or not the mouse has been clicked when the cursor is positioned in the area of the mark-in button 27c or the mark-out button 27f. This determination is based on an interrupt command supplied to the CPU 10. If the mark-in button 27c is clicked, it is determined that an IN point has been designated, and the process proceeds to step SP52. If the markout button 27f is clicked, it is determined that an out point has been designated, and the process proceeds to step SP55.

  In step SP52, in-point clip image data is formed. This IN-point clip image data is data formed when the video data stored in the frame memory 12c is read out to the VRAM 13b, and is 1/16 of the video data recorded in the frame memory 12c. Sampling rate is reduced to be a quantity. The clip image data is composed of 95 pixels × 60 pixels.

  In step SP53, the clip image data stored at the position of the in-clip display area 27a of the VRAM 13b is displayed in the in-clip display area 27a according to the data read from the VRAM 13b.

  In step SP54, the IN-point clip image data marked earlier and displayed in the in-clip display area 27d is moved to the clip display area 28.

  In step SP55, out-point clip image data is formed. The out-point clipped image data is data formed when the video data stored in the frame memory 12c is read out to the VRAM 13b, and is 1/16 of the video data recorded in the frame memory 12c. Sampling rate is reduced to be a quantity. The clip image data is composed of 95 pixels × 60 pixels.

  In step SP56, the clip image data stored at the position of the out clip display area 27d of the VRAM 13b is displayed in the out clip display area 27d according to the reading of the data from the VRAM 13b.

  In step SP57, it is determined whether or not the previously marked clip image data is IN-point clip image data. If the previously marked clip image data is IN-point clip image data, the process proceeds to step SP58. If the previously marked clip image data is OUT-point clip image data, the process proceeds to step SP59. move on.

  In step SP58, it is determined whether or not to newly register as an event. When the “NEW EVENT” button 33 is clicked, it means that a new event is registered.

  Step SP59 performs the same processing as step SP28.

  In step SP60, an event is registered. In this way, marking of the OUT point is performed after the IN point, and when the “NEW EVENT” button 33 is clicked, it is registered as an event. The description of the second management record data created for event registration can be better understood with reference to the description of FIGS.

  In step SP61, the clip image data of the in-point of the generated event is copied to the event display area 29.

  In step SP62, it is determined whether or not playback stop of the video data displayed on the playback video screen 23a is designated. If stop is designated, the process proceeds to step SP63.

  In step SP63, a stop command is output to the hard disk array 2 and the process ends.

  The present invention relates to an editing system. For example, this is suitable for materials that require speediness such as sports broadcasts and news reports. It can also be used in computer graphic devices.
