Background Art Conventionally, in a post-production field for editing editing materials in a broadcasting station or the like, tape editing using magnetic tape is generally used as a recording device for recording editing materials. Tape editing is a task of building a story of a program while selecting a scene by searching for a material tape and determining only an edit point, and dubbing to a master tape. However, since the tape editing operation must repeat the cue up through trial and error to access the desired frame of the recorded material on the tape, it takes a long time to determine the edit point. Moreover, dubbing from tape to tape is required for each cut for which an edit point is determined, and since the VTR of the raw material tape and the VTR of the master must be controlled each time, a huge time is required for the editing work. As a result, the editing worker could not be freed from the tape editing work requiring mental concentration for a long time.

In the production of news programs, press programs, and sports programs at broadcasting stations, it is required to provide viewers with the same-day events occurring in various places, that is, breaking news. In particular, in the production of such news programs, press programs, and sports programs, not only an assemble edit that combines edited scenes, but also a mosaic effect or A / B roll on the image of the edited scenes. Effects such as changing the tone of the speaker and removing ambient noise from the coverage site must be added to the sound of the edited scene.

In order to add an effect or the like, not only an editing operation for manipulating the source VTR and the master VTR but also a separate editing operation for manipulating a video switcher device or a special effect device for performing such an effect was required.

Therefore, there is a problem in the conventional editing apparatus that a video program provided to a news program, a news program, and a sports program cannot be produced quickly and quickly.

It receives through the control unit and controls the operations of the DMA controllers 61B and 61C and the SCSI protocol controllers 61D and 61E based on the control command indicated by the control signal S12. As described above, the CPU 61A generates the control signal S60 and outputs it to the data input / output block 60 to control the operation of the data input / output block 60.

In addition, the CPU 61A manages the write addresses of the disk array blocks 62 and 63 in the same way as the time code of the data to be recorded, thereby recording the address of the data indicated by the time code on the basis of the time code. It is made for easy searching. Specifically, the CPU 61A stores in a built-in memory a correspondence table in which all recording addresses of video data recorded in units of frames are recorded in the disk array block 62, and all time codes of frames to be recorded. Similarly, the CPU 61A stores in the built-in memory a correspondence table in which all recording addresses of audio data recorded in units of frames are recorded in the disk array block 63, and all time codes of frames to be recorded. Therefore, by simply specifying a time code from the outside, the recording address can be easily found by referring to the correspondence table, and video data and audio data can be quickly reproduced.

The DMA controller 61B of the video system reads the video data from the buffer memory 60C of the data input / output block 60 at the time of data writing in response to a command from the CPU 61A, and the data input / output block 60 at the time of data reproduction. Video data is written into the buffer memories 60F and 60I. In addition, the SCSI protocol controller 61D of the video system records a command from the CPU 61A, video data in units of frames accepted by the DMA controller 61B, and a time code assigned to a frame of video data at the time of data recording. The data is converted into SCSI format data S67 and sent to the disk array block 62 for video data, and the recording of the video data is instructed to the disk array block 62. FIG. When the data is reproduced, the SCSI protocol controller 61D receives the video data S67 of the SCSI format reproduced from the disk array block 62, converts it to the original data format, and sends it to the DMA controller 61B.

Similarly, the DMA controller 61C of the audio system reads audio data from the buffer memory 60K of the data input / output block 60 at the time of data writing, in response to a command from the CPU 61A, and at the time of data reproduction, the data input / output block. Audio data is recorded in the buffer memories 60M and 60P at 60. In addition, the SCSI protocol controller 61E of the audio system records a command from the CPU 61A, audio data in units of frames accepted by the DMA controller 61C, and a time code assigned to a frame of audio data at the time of data recording. The data is converted into SCSI format data S68 and sent to the disk array block 63 for audio data, and the recording of the audio data is instructed to the disk array block 63. FIG. When the data is reproduced, the SCSI protocol controller 61E receives the audio data S68 of the SCS1 format reproduced from the disk array block 63, converts it to the original data format, and sends it to the DMA controller 61C.

The disk array block 62 for video data and the disk array block 63 for audio data each comprise a disk array device having a plurality of hard disks therein, and simultaneously drive the plurality of hard disks in parallel to perform video data. I am made to record audio data. In addition, the disk array blocks 62 and 63 are designed to have redundancy when recording data, so that even when any of the hard disks in the disk array device fail, the disk array blocks 62 and 63 are recorded on the failed hard disk. It is designed to recover existing data (also called rebuild operation). In addition, a disk array device having such a data rebuilding function is generally called a Redundant Array of Inexpensive Disks (RAIP).

Here, these disk array blocks 62 and 63 will be described in detail with reference to the drawings. However, since the disk array blocks 62 and 63 basically have the same configuration, only the disk array block 62 will be described here. As shown in FIG. 9, the disk array block 62 is roughly divided into a buffer memory 62A, a disk array controller 62B, a data multiplexer 62C, a parity calculation circuit 62D, and a plurality of SCSI protocol controllers ( 62E to 62I), and a plurality of hard disks 62J to 62N.

The buffer memory 62A is a memory for temporarily storing data. The buffer memory 62A sequentially receives and stores the SCSI format data S67 sent out from the system control block 61 shown in FIG. The data transferred at 62C) is temporarily stored in accordance with the data transmission.

The disk array controller 62B is a circuit that controls the operation of the entire block, such as a recording operation or a reproducing operation, in the disk array block 62. The disk array controller 62B receives data on the control command from the system control block 61 among the data stored in the buffer memory 62A through the command data path 62P, and the command corresponding to the control command. The operation of each unit is controlled by sending data to the data multiplexer 62C, the SCSI protocol controllers 62E to 62I, and the hard disks 62J to 62N via the command data bus 62P.

The data multiplexer 62C reads data to be recorded, such as video data, from the buffer memory 62A at the time of data recording, and divides the data into respective hard disks 62J through 62M through the SCSI protocol controllers 62E through 62H. At the same time, the parity calculation circuit 62D notifies the divided data contents. When the data multiplexer 62C regenerates the data, the data multiplexer 62C collects the data reproduced from each of the hard disks 62J to 62M into one, and sends the data to the buffer memory 62A. If there is data that cannot be reproduced, the data is reproduced by the reconstruction operation based on the parity data supplied from the parity calculation circuit 62D.

The parity calculating circuit 62P calculates parity data of the data based on the data contents divided by the data multiplexer 62C at the time of data writing, and transmits the parity data to the hard disk 62N through the SCSI protocol controller 62I. Supply. The parity calculating circuit 62P sends parity data reproduced by the hard disk 62N to the data multiplexer 62C when there is data that cannot be reproduced by the hard disks 62J to 62M during data reproduction.

When the SCSI protocol controllers 62E to 62I write data, the data to be written supplied from the data multiplexer 62C or the parity data supplied from the parity calculating circuit 62P conforms to the recording format of the hard disks 62J to 62N. The data is converted into a data format, and the converted data is sent to the hard disks 62J to 62N. In addition, the SCSI protocol controllers 62E to 62I convert data reproduced from each of the hard disks 62J to 62N into a data format of the SCSI format at the time of data reproduction, and this is the data multiplexer 62C or the parity calculating circuit 62P. Send it out.

When the SCSI protocol controllers 62E to 62I detect that data reproduction cannot be performed due to a failure or the like of the hard disks 62J to 62N when the hard disks 62J to 62N are accessed, the SCSI protocol controllers 62E to 62I display the detection result. And the data reconstruction can be instructed by the disk array controller 62B to the data multiplexer 62C.

The hard disks 62J to 62N are data storage means for distributing and recording data in parallel to be recorded, such as video data. In such an example, four hard disks 62J to 62M are provided to distribute data, but the number is not particularly limited. The hard disks 62J to 62M sequentially record the data supplied from the SCSI protocol controllers 62E to 62H at the time of data recording in the desired recording area, and at the same time read the data sequentially to reproduce the SCSI protocol controllers 62E to 62H. To be sent. In this way, the plurality of hard disks 62J to 62M are provided so that data is distributed and recorded, so that even a large amount of data such as video data can be reliably recorded in the disk array block 62.

The hard disk 62N is data storage means for recording parity data calculated on the basis of data to be recorded. The hard disk 62N sequentially records the parity data supplied from the SCSI protocol controller 62I in a desired recording area at the time of data recording, and reads out the parity data sequentially and sends it to the SCSI protocol controller 62I at the time of data reproduction. In this way, the parity data calculated on the basis of the data to be recorded is recorded on a hard disk 62N different from the hard disks 62J to 62M for recording the data to be recorded. Even when data cannot be reproduced at 62J to 62M, data can be reconstructed based on the parity data.

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

In the parity calculating circuit 62P, a logic calculating means 70 as shown in FIG. 10A is provided, and the logic calculating means 70 calculates parity data. The logical operation means 70 includes data D0 allocated to the hard disk 62J, data D1 allocated to the hard disk 62K, data D2 allocated to the hard disk 62L, and a hard disk ( The data D3 allocated to 62M is added, and if the addition result is even, parity data PD having a value of "1" is output. If the addition result is odd, parity data of a value "0" is output. If the addition result is "0", the parity data PD having the value "1" is output as an even number.

Specifically, as shown in Fig. 10B, for example, when all of the data D0 to D3 are the values "0", the logic calculating means 70 becomes parity with the value "1" because the addition result is "0". When the data PD is output, and the data D0 to D2 are the value "0" and the data D3 is the value "1", the addition result is "1". ) The parity data PD shown in the diagram of Fig. 10B is also output in the same principle with respect to other data combinations. The parity data PD thus calculated is recorded on the hard disk 62N through the SCSI protocol controller 62I as described above.

If the data D2 recorded on the hard disk 62L cannot be reproduced due to a failure of the hard disk 62L at the time of reproduction, the disk array controller 62B detects that the reproduction cannot be performed by the SCSI protocol controller 62G. Is received, and the data multiplexer 62C instructs data reconstruction using parity data. As shown in Fig. 11A, the data multiplexer 62C receives the data D0 reproduced from the hard disk 62J and the data reproduced from the hard disk 62K with respect to the logical operation means 71 installed therein. D1), the data D3 reproduced from the hard disk 62M and the parity data PD reproduced from the hard disk 62N are inputted, and the reconstruction of the data D2 is performed by the logical operation means 71. To execute the operation. The logic calculating means 71 adds the input data D0, D1, D3 and the parity data PD, like the logic calculating means 70 for calculating the parity data PD, and if the addition result is even The reconstruction data D2 having the value "1" is output, and if the addition result is odd, the reconstruction data D2 having the value "0" is output.

Specifically, as shown in FIG. 11A, for example, when the data D0, D1, and D3 are the values "0" and the parity data PD is the value "1", the logical operation means 71 adds up. Since the reconstruction data D2, which becomes the value "0", is output as "1", and the data D0, D1, and PD are the value "0", and the data D3 is the value "1", the addition result is Similarly, since it becomes "1", the reconstruction data D2 which becomes the value "0" is output. The reconstruction data D2 as shown in the chart of Fig. 11B is also output with respect to the combination of other data on the same principle. As can be seen by contrasting Figs. 11B and 10B, the data D2 which cannot be reproduced is correctly restored by the failure of the hard disk 62L.

In this way, the disk array block 62 calculates the parity data PD based on the data D0 to D3 to be recorded and records the parity data PD on the hard disk 62N when data is recorded. Even when data D0, D1, D2 or D3 cannot be reproduced due to a failure of the hard disk 62J, 62K, 62L or 62M at the time of data reproduction, the data D0, which cannot be reproduced based on the parity data PD, can be reproduced. D1, D2 or D3) can be reliably restored.

Therefore, it can be easily identified.

In the log window 93, as shown in FIG. 18, a device icon 165 is displayed for each clip card to indicate from which source device the event represented by each clip card 179 is generated. do. That is, by displaying the device icon 165 for each clip card 179, it is determined whether or not the event represented by each clip card 179 is an event generated from an image of which source device. It can be easily identified.

In the program window 94, as shown in FIG. 16, a device icon 165 is displayed for each event to indicate each event registered on the timeline and an event generated from which source device. That is, by displaying the device icon 165 for each event on the timeline, the device icon 165 can easily identify whether each event is an event generated from an image of a source device.

The reason why the editing operator must recognize the source device of each event when creating the editing program is explained. The local storage device 8 used in the editing device of this embodiment uses a randomly accessible recording medium, and furthermore, has the ability to reproduce multi-channel video and audio in real time. There is no limitation as regards processing. However, in the case of a recording medium such as VTR 7 that cannot be randomly accessed, it takes time to rewind the tape in order to cue up, so that many restrictions are placed on the effect setting and program generation processing. For example, it is not possible to write a program that allows two or more events generated from the material on the tape of the VTR 7 to be closely arranged on the timeline. Similarly, a program in which two or more events generated from the tape of the VTR 7 are arranged in the base video line and the overlay video line so as to overlap in time cannot be created.

In addition, the material generated from the server is not limited in effect setting and program generation processing as in VTR. As a result, there is a limitation with respect to various types of effect settings, because there is a delay in receiving the video signal.

For the above reasons, the editing operator must recognize the source device of each event in creating the editing program.

In this way, by providing a device icon to each event, the source device can be easily recognized. Therefore, when the effect on the event is set, it can be easily determined whether the source device of the event is the VTR 7, the daily server 6, or the local storage device 8. For example, when the source device of the event to which the effect is to be added is the VTR 7, and the source device of the event set near the event on the timeline also turns out to be the VTR, either event is selected. It is possible to instruct the local memory 8 to download from the VTR 7. That is, the editing operation on the material can be more surely performed.

3. File Manager

In the editing apparatus of this embodiment, a file manager manages various data such as a material downloaded into the local storage device 8, a finished video program, a program list stored in the hard disk (HDD) of the computer 2, and a log clip. It is. That is, the registered event is managed by the file manager as one file.

In addition, the file manager manages each file to be stored in a predetermined specific folder. For example, log files are stored in the log folder, program list (EDL) files are stored in the program list folder, material files are stored in the material folder, and edits are stored to store data about the completed video program (Edited Master). The master file is to be stored in the editing master folder.

All files managed by this file manager have file information as shown in FIG. The file information includes the file name 331, the event name 332, the time point 333 of the in-point, the clip address 334 of the in-point, the time code 335 of the out-point, the clip address 336 of the out-point, and the duration 337. ), File type information 338, file position information 339, source device ID information 340, creation date and time 341, video adjustment information 342, audio adjustment information 343, text data 344, Program list names 345 and the like.

This file name 331 is data for indicating what event is generated from which file name, and the name of the source file name is registered. The source file name is registered when the source device is the local storage device 8 or the server 6, but the reel name of the tape cassette is registered when the source device is the VTR.

The event name 332 is a name that can be given arbitrarily by the editing operator. The event name is the same as the clip name already described, and only the name given to the clip displayed in the log window 93 is called the clip name, and the name given to the event displayed in the time window 95 is called the event name. It is called.

The clip address 334 of the in point and the clip address 336 of the out point represent the address of the hard disk HDD of the computer 2 in which the stamp pictures generated when marking the in and out points are stored.

The file type information 338 indicates whether the file is a file representing a log clip, a file representing a program list, a file representing a material downloaded to a local storage device, or a completed program recorded in the local storage device. Information. "Log" indicates that the file is a log clip, "EDL" indicates that the file is a program list, "Material" indicates that the file is a material downloaded to a local storage device, and "Master" indicates that file. This indicates that the program has been recorded in the local memory.

The file position information 339 is data indicating whether the file is a data file recorded on the hard disk HDD of the computer 2 or a material file in the local storage device 8. "C" represents a data file in a computer, and "L" represents a material file in a local storage device.

The source device information is information indicating on which source device the material represented by the file information is recorded. "S" indicates that the source device is the server 6, "L" indicates that the source device is a local storage device, "V" indicates that the source device is a VTR, "A" means AUX (auxiliary) material "I" has shown that it is an internal material.

4. Operation of Editing Process

4-1. Event creation processing

First, with reference to the flowchart of FIG. 20, the event creation process which is the first process of the edit process is demonstrated. In addition, the "operation of the editing operator" used by the following description means that the editing operator which operates the computer 1 has the graphic image displayed on the monitor 2B, for example, with a pointing device, such as a mouse 2D. Click, drag, and drop operations, or direct manipulation of the keyboard 2C, the mouse 2D, the dedicated controllers 4, 5, and the like.

First, in step SP301, the CPU 21 of the computer 1 selects a source device to be controlled in response to an operation of the editing operator. Specifically, when the editing operator clicks any one of the source selection buttons 102A to 102E of the viewer window 92 displayed on the monitor 2B as a GUI image, the CPU 21 selects the source device to be controlled. Will be decided. For example, when the source selection button 102A is clicked by the operator, the CPU 21 determines that the daily server 6 is selected as the source device, and when the source selection button 102B is clicked by the operator, the CPU ( 21 determines that the VTR 7 is selected as the source device, and when the source selection button 102C is clicked on by the operator, the CPU 21 determines that the local storage device 8 is selected as the source device.

In step SP302, the CPU 21 searches for a work file registered in the source device designated in step SP301 in response to the operation of the editing operator. Specifically, on the monitor 2B of the computer 1, a material search dialog 300 as shown in FIG. 21 is displayed. The dialog 300 includes, as input items, a creation date and time input table 301, a file name input table 302, a file type input table 303, an audio mode selection table 304, and a like, for inputting a creation date and time of material data. The program name input list 305 and a search execution instruction button 306 are provided. For example, if the keyword "FIRE" is input to the file name input list 302, only files in which the file name "FIRE" is included in the file name can be searched. The search condition is set by the editing operator inputting desired data in each input list of the dialog 300. Then, when the search execution button 306 is pressed by the editing operator, the CPU 21 sets the condition set in the dialog 300. Accordingly, a search process for searching for a file registered in the source device is executed.

The CPU 21 refers to the file information stored in the RAM 21B and searches for a file meeting the condition set in the dialog 300. The CPU 21 then displays the search result as a file list 310 as shown in FIG.

In step SP303, the CPU 21 selects a desired file from the file list of the search result in step SP302 in response to an instruction of the editing operator. Specifically, when the editing operator clicks on the desired file name from the file list 310, the CPU 21 selects the file designated by the editing operator.

In step SP304, the CPU 21 reproduces the video data and the audio data included in the selected file, and the reproduced video data is displayed in the viewer window 92, and the reproduced audio data is displayed in the speakers 11 and 12. Control the source device and the editing apparatus 3 selected to be played back. As an example, a case of reproducing a file recorded in the daily server 6 will be described as an example.

First, the CPU 21 supplies a control signal for reproducing the file selected in step SP303 from the daily server to the daily server 6 via the LAN 10. The daily server 6 supplies the video processing and audio data included in the designated file based on the control signal to the editing processing apparatus 3 as the digital signal S7 resulting from the SDI format standard. The supplied digital signal S7 is input to the input terminal IN1 of the matrix switcher portion 3B of the editing processor 3.

The CPU 21 uses the system control unit 3A of the editing processing apparatus 3 to activate the cross point P19 for connecting the input terminal IN1 and the output terminal OUT9 to the matrix switcher 3B. To control. As a result, the SDI format digital signal S7 supplied to the input terminal IN1 is output as the SDI format digital video signal S26 from the output terminal OUT9 and supplied to the image processing unit 3C.

The SDI format digital video signal S26 output from the output terminal OUT9 is supplied to the demultiplexer 51D of the image processing section 3C. The demultiplexer 51D extracts the digital video signal from the effective payload of the data in the SDI format, and the extracted digital video signal is output video through the switcher block 52, the special effect block 53, and the mixer block 54. It is output as a signal S31.

The digital video signal S31 output from the image processing section 3C is supplied to the input terminal IN9 of the matrix switcher section 3B again. The CPU 21 controls the matrix switcher 3B to activate the intersection point P95 for connecting the input terminal IN9 and the output terminal OUT5 via the system control section 3A of the editing processing apparatus 3. To control. As a result, the digital video signal S31 supplied to the input terminal IN9 is output to the computer 2 from the output terminal OUT5 as the digital video signal S2 via the output processor 46.

The digital video signal S2 output from the editing processing apparatus 3 is supplied to the video processor 22 of the computer 2 and displayed on the computer monitor 2B viewer window 92 via the display controller 23.

On the other hand, the CPU 21 supplies the SDI format digital signal S7 supplied to the input terminal IN1 to the audio processing unit 3D through the system control unit 3A of the editing processing unit 3, and the matrix switcher unit. (3B) is controlled. That is, the CPU 21 controls the matrix switcher 3B to activate the intersection point P111 for connecting the input terminal IN1 and the output terminal OUT11 via the system control section 3A of the editing processing apparatus 3. ). As a result, the SDI format digital signal S7 supplied to the input terminal IN1 is output not only from the output terminal OUT9 but also from the output terminal OUT11 as the digital output signal S28 to the audio processing unit 3D. do.

Since the video data is superimposed on the effective payload portion of the SDI format digital output signal S28 and the audio data is superimposed on the auxiliary data portion, the separator 56A of the speech processing unit 3D is a digital signal S28 format in the SDI format. Separate audio data only from The CPU 21 transmits the audio signal S48 separated through the system control unit 3A of the editing processing unit 3 to the speakers 11 and 12 as the output audio signals S17 and S18 through the mixer block 57. The audio processing unit 3D is controlled to supply.

In step SP305, according to the operation of the editing operator, the CPU 21 of the computer adjusts the video data and audio data reproduced from the selected source device. Specifically, when the video dedicated key 167A of the viewer window 92 is clicked by the editing operator, the CPU 21 of the computer 2 monitors the video level setting dialog 170 as shown in FIG. (2B). The editing operator can move the slider 170 with the mouse 2D to set a desired level of brightness or color.

The CPU 21 of the computer 2 stores each level set by the video level setting dialog 170 via the system control unit 3A as video adjustment information of file information. In addition, the CPU 21 processes the video signal of the image processing unit 3C so that the brightness level and color level of the video data reproduced from the selected source device become the brightness level and color level set by the video level setting dialog 170. Control circuits 52E and 52F.

The video level adjustment process described above is a process performed only when the video dedicated key 167A is clicked on by the editing operator. If such video level adjustment processing is not performed, the video signal is adjusted by default values preset as the reference brightness level and the reference color level.

On the other hand, when the audio dedicated key 167A of the viewer window 92 is clicked by the editing operator, the CPU 21 of the computer 2 monitors the audio-video level setting dialog 172 as shown in FIG. It displays on (2B). The editing operator can set the desired audio input / output level by adjusting the slider 173A and moving the fader 174A with the mouse 2D.

The CPU 21 of the computer 2 stores the audio level set by the audio-video level setting dialog 172 through the system control unit 3A as the audio adjustment information of the file information. In addition, the CPU 21 controls the mixer block 57 of the audio processing unit 3D so that the input / output level of the audio data reproduced from the selected source device becomes the input / output level of the audio data set by the audio level setting dialog 172. do.

Incidentally, the above-described audio level adjustment processing is a process performed only when the audio dedicated key 167B is clicked on by the editing operator. If such audio level adjustment processing is not performed, the audio signal is adjusted by a default value preset as a reference input / output level of the audio data.

In step SP306, the CPU 21 searches for the video material recorded in the selected source file based on the operation of the editing operator. Specifically, when the editing operator operates the device control unit 96 of the viewer window 92, the CPU 21 of the computer 2 controls the reproduction operation of the source device selected to correspond to the operation. As a result, video data of the speed specified by the editing operator is displayed in the viewer 106 of the viewer window 92.

In step SP307, the CPU 21 sets the in point and the out point based on the operation of the editing operator. Specifically, when the video image of the selected file is displayed as the moving picture in the viewer 106 by the searching process of step SP306, the editing operator searches for the video frame as in step SP306 so that the desired video frame is the viewer. When the mark in button 115 of the viewer window 92 is clicked when displayed in the viewer 106 of the window 92, the point of designation is specified at the timing when the mark in button 115 is clicked. When the mark-in button 115 is clicked, the CPU 21 responds to the click operation and uses the video data displayed in the viewer 106 at the clicked timing as a clip image (stamp picture) as a point image display unit ( 110). At the same time, the CPU 21 recognizes the time code given to the video frame at the marked point as the time code of the point.

After the point of designation is specified, the editing operator also searches for the video frame as shown in step SP306, and when the desired video frame is displayed in the viewer 106 of the viewer window 92, the mark out button 116 is clicked. The out point is specified at the timing when the mark out button 116 is clicked. When the mark-out button 116 is clicked, the CPU 21 responds to the click operation and uses the video data displayed in the viewer 106 at the clicked timing as the clip image (stamp picture) as the out point image display unit ( 112). At the same time, the CPU 21 recognizes the time code given to the video frame at the marked timing as the time code of the out point.

When the out point is specified in this manner, the CPU 21 calculates the time between the in point and the out point from the set time code of each of the set in and out points, and displays the calculated time in the DUR display field 114 on the viewer window 92. do.

In step SP308, the CPU 21 previews the period designated by the in and out points set in step SP307, based on the operation of the editing operator. Specifically, when the editing operator clicks on the preview button 117 of the viewer window 92, the CPU 21 controls the system control unit of the editing controller 3 so as to reproduce the video frame from a few seconds before the in-point to the out-of-out video frame. Through 3A), the appropriate source device (daily server 6, local memory 8 or VTR 7) is controlled.

The preview process in the editing system of this embodiment is a process performed assuming that an event generated by the process of step SP307 is registered at the position of the current line 139 of the timeline 95. In addition, the preview process does not start playback at the point in time, but starts playback from a few seconds before the point (for example, five seconds).

In other words, the preview process virtually registers an event on the timeline to start playback from a few seconds before the in-point point. Thus, before actually registering the event on the timeline, a connection between the event to be registered and the event immediately before it is registered. You can check it virtually.

If, as a result of the preview, the material itself, the setting of the in-point and the out-point, etc. are not satisfactory, the process can return to step SP301 or SP306 again.

In addition, step SP308 is not an essential process, but a process performed only when the preview button 117 is clicked by an editing operator.

In step SP309, according to the operation of the editing operator, the CPU 21 of the computer 2 determines whether or not a process for downloading the materials of the daily server 6 and the VTR 7 into the local storage device 8 is designated. Judge. Specifically, when the editing operator clicks the download button 123A in the viewer window 92, the CPU 21 determines that the download process is specified. In addition, the download process is a process that can be performed only when the daily server 6 or the VTR 7 is designated as the source device in step SP301. If download processing is designated by the editing operator, the CPU 21 opens the download processing setting dialog 320 as shown in FIG. 25 and proceeds to step SP310. On the other hand, if download processing is not specified by the editing operator, the flow advances to step SP312.

In step SP310, the CPU 21 starts the download process in accordance with the operation of the editing operator. Specifically, before the CPU 21 actually starts the download process, the editing operator first inputs the settings necessary for the download process in the download process setting dialog 320. The file name input unit 321 is a setting list for setting a new file name given to a file downloaded to the local storage device, and the start time code setting unit 322 sets the start time code of the file downloaded to the local storage device. The transmission speed setting table 323 is a setting list for setting the transmission speed transmitted from the selected source device to the local storage device.

When the editing operator enters the necessary settings in the download processing setting dialog 320 and clicks the execute button 324, the CPU 21 transfers the video data from the in point to the out point of the designated file to the local storage device 8. To download, control the source device and the edit controller 3. The CPU 21 and the editing controller of the computer 2 are exemplified below when the video data and audio data of the out point are downloaded to the local storage device 8 at the in point of the file recorded in the daily server 6. The operation of (3) will be described.

First, the daily server 6 starts reproduction from the video data and audio data of the point in time of the designated file, and converts the reproduced video signal and audio signal as a digital signal S7 resulting from the standard of the SDI format into an editing processing apparatus ( Supply to 3). The supplied digital signal S7 is input to the input terminal IN1 of the matrix switcher portion 3B of the editing processor 3.

Since the digital signal S7 reproduced from the daily server 6 must be downloaded to the local storage device 8, the CPU 21 inputs the input terminal via the system control section 3A of the editing processing device 3; The matrix switcher part 3B is controlled to activate the crossing point P 11 for connecting IN1 and the output terminal OUT1. As a result, the SDI format digital signal S7 supplied to the input terminal IN1 is output from the output terminal OUT1 as the SDI format digital signal S15 via the output processor 43.

The local storage device 8 records the digital signal S15 supplied from the editing processing device 3 on an appropriate recording medium by using a RAID algorithm. As a result, video and audio data recorded in the daily server 6 are downloaded to the local storage device 8.

On the other hand, in order to display the video signal downloaded to the local storage device in the viewer window 92 during such a download process, first, the CPU 21 inputs through the system control unit 3A of the editing processing device 3. The crossing point P 19 of the matrix switcher portion 3B is activated to output the SDI format digital signal S7 supplied to the terminal IN1 to the output terminal 9. As a result, the SDI format digital signal S7 supplied to the input terminal IN1 is downloaded to the local storage device via the output terminal S15, and at the same time, via the output terminal OUT9, the digital video signal of the SDI format ( It is supplied to the image processing part 3C as S26.

The digital video signal S26 in SDI format output from the output terminal OUT9 passes through the image processing section 3C and is again supplied to the input terminal IN9 of the matrix switcher section 3B as the output video signal S31. . The CPU 21 sets the matrix switcher 3B to activate the intersection point P95 for connecting the input terminal IN9 and the output terminal OUT5 via the system control section 3A of the editing processing apparatus 3. To control. As a result, the digital video signal S31 supplied to the input terminal IN9 is output to the computer 2 from the output terminal OUT5 as the digital video signal S2 via the output processor 46.

The digital video signal S2 output from the editing processing apparatus 3 is supplied to the video processor 22 of the computer 2 and displayed on the viewer window 92 of the computer monitor 2B via the display controller 23. .

That is, the video data reproduced from the daily server 6 is downloaded to the local storage device 8 and displayed in the viewer window 92 of the computer 2. In the editing apparatus of the present embodiment, the processing for displaying the editing material in the viewer window 92 while downloading the editing material to the local memory device 8 is called "downloading process in the background".

In step SP311, according to the instruction of the editing operator, the CPU 21 controls the editing processing apparatus 3 to perform the download processing in the background. If the editing operator clicks the cancel button 325 of the download setting dialog 320 during the download process, the download process performed as the foreground process is performed as the background process. Specifically, when the cancel button 325 of the download setting dialog 320 is clicked on by the editing operator, the CPU 21 inputs the input terminal IN1 to which digital data from the daily server 6 is supplied, and the download. The intersection point P11 of the output terminal OUT1 to be maintained is kept in an active state, but the cross point P19 between the input terminal IN1 and the out terminal OUT9 for outputting to the image processing unit 3D. Control the matrix switcher portion 3B.

As a result, the digital signal S7 reproduced from the daily server continues to be downloaded to the local storage device 8, but the supply to the image processing unit 3C and the computer 2 is stopped. In other words, when viewed from the editing operator operating the computer 2, the download process is performed in the background that the operator cannot see.

In the processing of this step SP311, if the CPU 21 controls the editing processing apparatus 3 to process the local storage device as a download, the process returns to step SP301 again while performing the download processing in the background. The process then proceeds to editing the material.

In addition, when the download operator is not specified in the background by the editing operator in step SP311, the download process in the background is performed until the download process is completed.

Next, a normal editing process in which no download process is specified in step SP309 will be described with reference to the next step SP312.

In step SP312, the CPU 21 performs a scene name setting process in accordance with an operation of the editing operator. Specifically, when the scene change button 178A of the viewer window 92 is clicked by the editing operator, the process moves to the scene name setting process (step SP313), and when the scene change button 178A is not clicked, the process goes to step SP314. Then, the clip name and the event name are created using the scene name already set in the step SP314.

The scene name setting processing in step SP313 will be described.

First, the CPU 21 opens a scene name input dialog 180 as shown in FIG. 26A on the monitor 2B. When the pull-down button 182 for displaying a list of scene names installed in the dialog 180 is selected by the editing operator, the CPU 21 monitors the list of scene names 183 as shown in Fig. 26B (2B). Mark on. The list of scene names is a list of scene names used and registered by the editing operator during the previous editing operation, and is data stored in the RAM 21b as a history list.

When a scene name is selected from the list 183 displayed by the editing operator, the CPU 21 registers the selected scene name as the scene name used in the clip generation process and the event creation process described later.

In addition, without selecting the pull-down button 182, the editing operator may directly input the scene name into the scene name input box 181 directly with the keyboard 2C. In this case as well, the CPU 21 registers the input scene name as the scene name used in the clip generation process and the event creation process described later.

The reason why such a scene name is updated in the editing apparatus of the present embodiment is explained.

In the clip creation process and the event creation process described later, clip names and event names are assigned using scene names. Specifically, the clip name and the event name are generated with "scene name" and "serial number". That is, assuming that the scene name is updated to "FIRE" in step SP313, the following clip creation process has clip names such as "FIRE001", "FIRE002", and "FIRE003". The clips are created in order. For example, suppose that the scene name is updated to "SEA" in step SP313 afterwards. Similarly, in the subsequent clip creation process, "SEA001", "SEA002", and "SEA003" are the same. Clips with clip names are created in order.

In other words, the clip registered in the log window 93 can be classified for each scene name by setting the appropriate scene name when the editing operator changes the scene of the material. So even if you have created hundreds of clips, you can easily manage those clips. In addition, when searching for the clip of the local memory device 8 in step SP302, only the relevant clip can be searched easily by making a scene name into a keyword.

In step SP314, in response to the operation of the editing operator, the CPU 21 sets the entry mode. The entry mode is a mode for determining whether to enter (register) a work where the in and out points are set in the log window or to enter (register) in the timeline window. The entry mode has two modes, a log mode that registers a work where the in and out points are set as a clip in the log window, and a time line mode which registers the work where the in and out points are set as an event in the timeline window. One mode is configured to be specified.

Specifically, when the editing operator selects the log button 122B of the viewer window 92, the log mode is selected, and when the editing operator selects the timeline button 12 (2C) of the viewer window 92, the time is displayed. Line mode is selected. If the log mode is set, the process proceeds to step SP315, and if the timeline mode is set, the process proceeds to step SP316.

In step SP315, in response to the operation of the editing operator, the CPU 21 registers the material designated as the in and out points as an event. Specifically, when the editing operator clicks on the ADD button 122A of the viewer window 92, the CPU 21 registers the material designated as the in and out points as an event. At this time, the CPU 21 generates file information as shown in Fig. 27 for indicating the registered event.

In addition, since the log mode is selected in step SP314, the CPU 21 causes the clip name to be generated based on the stamp picture of the in-point stamp of the event, the time code of the in-point, and the scene name set in step SP313. Is displayed in the log window 93 as the clip card 179. FIG.

By repeating the process of step SP315 from step SP306, a plurality of events designated by the editing operator are registered. In the log mode, a plurality of clip cards 179 representing the plurality of events can be displayed in the log window 93.

In step SP316, in response to the operation of the editing operator, the CPU 21 registers the material designated as the in and out points as an event. Specifically, as in step SP315, when the editing operator clicks on the ADD button 122A of the viewer window 92, the CPU 21 registers the material designated as the in and out points as an event. At this time, the CPU 21 generates file information for indicating the registered event, as shown in FIG.

In addition, since the timeline mode is selected in step SP314, the CPU 21 attaches the video event to the position of the current line 139 of the base video line 132A, and attaches the audio event to the base audio line 132B. ) At the current line 139.

By repeating the process of step SP316 in step SP306, a plurality of events designated by the editing operator are registered. In the timeline window, the plurality of events can be pasted to a desired position of the base video and the base audio line 132 of the timeline 95.

In addition, the event generated in the log mode and the event generated in the timeline mode are exactly the same. The only difference between the log mode and the timeline mode is that the generated event is displayed in the log window 93 as a clip card or in the timeline 95 as an event.

4-2. Program list creation processing

Next, a program list creation process for creating a program list using the events created by the event generation process of step SP301 to step SP315 will be described.

The flowchart of FIG. 27 is a figure for demonstrating the operation | movement of a program list preparation process. The flowchart shown in FIG. 27 is a flowchart when a program list is created using the event displayed as the clip card 179 in the log window 93.

First, in step SP401, the events displayed as the clip card 179 in the log window 93 are listed on the timeline. As such, there are two methods for arranging events on the timeline.

The first method is a method in which an editing operator inserts a clip card at a desired position on the timeline 95 using drag and drop using the mouse 2D. Specifically, by clicking on the clip card 179 displayed in the log window 93 with the mouse 2D, the clip card becomes active and becomes draggable. Next, when the clip card 179 is dragged and dropped to the desired position of the timeline 95, a video event corresponding to the clip card 179 is inserted at the drop position on the base video line 132A, and the base audio line is inserted. The audio event corresponding to the clip card 179 is inserted at the drop position on 132B.

The second method is a method of automatically arranging the clip card 179 on the timeline 178B using the direct entry mode. First, when the log window 93 direct entry button 180 is clicked by the editing operator, the normal mode is changed to the direct entry mode. The direct entry mode is a mode that can be arranged on the timeline by simply clicking the clip card 179 displayed in the log window 93 without dragging and dropping. Specifically, in the direct entry mode, when the editing operator clicks the clip card 179 of the log window 93, it corresponds to the clip card 179 clicked at the position of the current line 139 of the timeline 95. Video events and audio events are inserted.

Also, as the event is inserted, the current line 139 automatically moves to the position of the out point of the newly inserted event by the direct entry mode. That is, when the clip card 179 of the log window 93 is clicked in order, it is inserted in the clicked order on the right side of the timeline 95.

By using the direct entry mode in this manner, the clip card 179 displayed in the log window 93 can be attached to the timeline 95 by simply clicking without dragging and dropping. Therefore, when a large number of clip cards 179, not several, must be pasted on the timeline, the drag and drop operation for each clip card 179 can be omitted by the direct entry mode. In addition, the editing operation can be simplified and the editing time can be shortened.

In step SP402, the CPU 21 sets the mixdown of audio attached to the timeline 95 in accordance with the operation of the editing operator. The mixdown process is a process for setting the output level of four tracks set for an audio event and setting the routing for four channels of the final audio output (program out) of the four tracks.

First, when the audio mixdown dialog selection button 162 is clicked from the toolbar of the program window 94, the audio mixdown dialog 200 is displayed on the graphic user interface 90.

The dialog 200 includes four tracks T1 to T4 (or two tracks) of each audio event set in base audio (BASE), sub audio (SUB), voice over 1 (VO1), and voice over 2 (VO2). Output routing section 201 for setting how T1 to T2 are output in correspondence with the final audio output (program out) channels Ch1 to Ch4, respectively, and four tracks T1 to T4 of each audio event. A track fader section 208 for setting audio levels for the respective tracks, a fader panel assigning section 207 indicating how track faders formed in the dedicated controller 5 are assigned to the four tracks T1 to T4, and audio. By using the fader assign button 202 to open the setting dialog for allocating the four fader levers installed in the dedicated controller 5 for each track of the line, and the four fader levers installed in the dedicated controller 5. And an on / off button 202A indicating whether to turn on or off the mode for manually adjusting the audio level of each track.

In this output routing section 201, each track can be routed to a desired output channel by clicking on the crosspoint button corresponding to the desired output channel Ch1 to Ch4 position for each track T1 to T4.

For example, in the example shown in FIG. 28, the track T1 is routed to the output channel Ch1 by clicking the cross point button 201A of the track T1 of the event on the base audio line 132B. It is shown. In the same manner below, the track T2 is routed to the output channel Ch2, the track T3 to the output channel Ch3, and the track T4 to the output channel Ch4. Similarly with respect to the sub audio line 134, the voice over 1 line 138A, and the voice over 2 line 138B, the tracks T1 to T4 of the audio event of the sub audio line are respectively output channels Ch1 to Ch4. And tracks T1 and T2 of the audio event of voice over 1 to output channels Ch1 and Ch2, respectively, and tracks T1 and T2 of the audio event of voice over 2, respectively, to output channels Ch3. And Ch4).

When the manual fader button 202 formed in the dialog for setting down 200 is clicked on, a fader assignment dialog 205 as shown in Fig. 29 is displayed.

The dialog 205 stores four tracks T1 to T4 (or two tracks T1 to T2) of audio events registered in the base audio, sub audio, voice over 1 and voice over 2 of the dedicated controller 5. It has an assignment panel 206 for setting which fader levers F1 to F4 are assigned .. In the assignment panel 206, a desired fader lever set for each track T1 to T4 set in each column. By clicking the buttons corresponding to (F1 to F4), each track T1 to T4 can be assigned to any of the fader levers F1 to F4.

For example, FIG. 29 shows that the tracks T1 and T2 of the bass audio are assigned to the first fader lever F1 by clicking the buttons 206A and 206B belonging to the tracks T1 and T2 of the bass audio. have. Likewise below, this indicates that the tracks T1 and T2 are assigned to the second fader lever F2 by clicking the buttons 206C and 206D of the tracks T1 and T2 of the sub audio, and further, the buttons 206E and 206F. Click to indicate that the tracks T1 and T2 of voice over are assigned to the third fader lever F3.

When setting the audio level of the tracks T1 to T4 of each audio line, the desired audio can be set by moving the slider 208A of the track fader unit 208 up and down with the mouse 2D. Further, when the on / off button 202A is turned on, manual adjustment by the fader lever of the dedicated controller is possible. Accordingly, the editing operator can move the fader levers F1 to F4 up and down to set the desired audio level in the tracks corresponding to the fader levers. At this time, if the editing operator operates the fader lever of the dedicated controller 5, following the operation of the fader lever, the slider 208A of the track fader section 208 of the mixdown setting dialog is automatically moved. .

In the fader assignment dialog 205, the assignment of the fader levers F1 to F4 of the dedicated controller to each track T1 to T4 of each audio line BASE, SUB, VO1 and VO2 can be freely set. . Therefore, for example, when the audio to be edited is only base audio BASE, fader levers F1 to F4 may be assigned to the tracks T1 to T4 of the base audio, respectively. That is, the audio lines BASE, SUB, VO1 and VO2 and the respective tracks T1 to T4 are not physically associated with the fader levers of the dedicated controller 5, but rather are software related to each audio line. And the relationship between the tracks T1 to T4 and the fader lever of the dedicated controller 5 can be changed in any way.

When the setting of the audio mixdown is finished in step SP402, the flow advances to the next step SP403.

In step SP403, in response to the editing operation of the editing operator, the CPU 21 opens an effect setting dialog 190 for setting the effect for the event on the timeline. Specifically, when the editing operator clicks the video effect button 159 in the program window 94, an effect setting dialog 190 as shown in FIG. 30 opens.

The effect setting dialog 190 includes an effect pattern unit 191 indicating an effect pattern currently set, a preferred pattern unit 192 displaying an effect pattern with a high frequency of use, and a transition setting unit for setting a transition of the selected effect ( 193), a video / audio selection unit 195 for selecting a target (video / audio) for setting an effect, a changing unit 198 for setting parameters for changing an effect, and a key for setting parameters for key signals A setting unit 199 is provided.

In step SP404, video and audio are selected as effect setting targets. If you have effects on both video and audio at the same time, click both the "Video" and "Audio" buttons 195. If you only have effects on either video or audio, click the "Video" or "Audio" button (195). Click on any one of the

In step SP405, the editing operator selects the desired effect. As a method of selecting such an effect, an effect can be selected by either of the following three methods.

The first effect selection method is a method of setting a desired effect by directly inputting a pattern number indicating an effect. For example, when the editing operator knows the desired effect pattern number in advance, if the pattern number of the desired effect pattern is directly input to the pattern number setting unit 191 with the keyboard 2C, the desired effect corresponding to the input pattern number is obtained. Is set.

The second effect selection method is a method of selecting a desired effect from a pattern of effects frequently used by the editing operator (hereinafter, referred to as a favorite pattern). Specifically, the CPU 21 always memorizes the pattern of the effect frequently used by the editing operator, and the icon representing the pattern of the effect frequently used on the preference pattern display unit 192 of the effect setting dialog 190. It is configured to be displayed. When the editing operator clicks on the desired effect pattern from the preference pattern display unit 192, the desired effect is selected.

The third effect selection method is a method of selecting a desired effect pattern from all pattern lists. When the editing operator presses the pattern list button 194, all registered effect patterns are displayed for each type, and the desired effect is selected by clicking the desired effect pattern therefrom.

When an effect is selected by any of these methods, an icon of the selected effect is displayed on the effect pattern unit 191. The effect is selected by this.

In step SP406, the desired transition time is set for the selected effect by the editing operator. When setting the transition time for the selected effect, by inputting the transition time (transition time) of the effect selected by the transition setting unit 193A on the dialog 190 from the keyboard or by selecting a desired transition time from a plurality of preset transition times. You can set the transition time.

In step SP407, effect parameters are set for the selected effect. Specifically, the effect parameter is, for example, a parameter related to the prediction of a video transition position, a parameter related to light that is an effect such as lighting, and a trial / shadow that is an effect such as drawing a shadow or a band. Parameters related to (Shadow), parameters relating to location (Location) which is a position for setting an effect, and the like, and various parameters can be set according to the type of effect. By using the changing unit 198 of the effect setting dialog 190, various parameters related to these effects can be set. In addition, on the dialog 190, a chroma key and / or an external key can be set by clicking on the key button 199.

In step SP408, according to the operation of the editing operator, the CPU 21 controls each source device and the editing processing apparatus so as to preview the set effect. By operating the fader lever 196 or the AT button (Auto button) 197 of the dialog 190, the editing operator can preview the set effect on the screen of the viewer 106.

When the set effect is a transition effect such as a wipe effect, the background image is displayed on the viewer 106 when the fader lever 196 is positioned at the top. In addition, as the fader lever 196 is dragged by the mouse and moved from the top to the downward direction, the fader lever 196 gradually transitions to the foreground image. In the state where the fader lever 196 is located at the bottom, the foreground image is displayed on the viewer 106. This makes it possible to preview the transition effect at any speed and position by manual operation of the fader lever 196.

In addition, a foreground image is an image which is inserted into a background image by execution of an image or animation effect which appears on a screen by execution of a transition effect, and an image which makes an effect pattern buried. The background image is an image into which an effect pattern in which the foreground image is buried by the execution of an image or an animation effect that is erased from the screen by execution of the transition effect is inserted.

In addition, the editing apparatus of this embodiment has two kinds of effects, transition effects and animation effects. A transition effect is a video effect that changes two images, such as a wipe effect or a page turn effect, and an animation effect is an effect having a special effect on an image such as a three-dimensional image space conversion, a spotlight effect, a zoom-up effect, It is an effect of inserting an image having a video effect into a certain image, such as a picture-in-picture effect.

In addition, instead of the manual operation of the fader lever 196, when the AT button (Auto button) 197 is clicked, the transition from the background image to the foreground image is performed at a transition speed preset for the effect. Specifically, when the AT button 197 is clicked, the fader lever 196 first moves to the highest position first, and then automatically moves downward gradually at a constant speed. In accordance with the movement of the fader lever 196, a transition effect of transitioning from the background video to the foreground video is executed at a constant speed. As a result, the transition effect can be previewed on the viewer 106.

In the step of performing the preview processing, the effect selected in step SP503 is not yet attached to the effect line 135 of the timeline 95 by the editing operator, so it is still unknown to which event this effect is set. none. Therefore, the background image and the foreground image required for the preview processing for previewing such an effect are virtually executed using the video signal that has already been set in the image processing unit 3C of the editing processing apparatus 3. This is because the background image and the foreground image may be any image because the preview 1 of such an effect is a preview process for checking whether the transition time set in the set effect itself and the set effect parameter are appropriate.

In fact, under the control of the matrix switcher unit 3B of the editing processing apparatus 3, the signal currently supplied as the video signal S24 to the image processing unit 3C is regarded as the foreground video, and the image processing unit 3C The signal supplied as the video signal S26 is used as the background video. In short, when attempting to preview such an effect, the CPU 21 of the computer uses the signal supplied as the video signal S26 to the image processing unit 3C as the background image, and the video signal S24 to the image processing unit 3C. The editing processing apparatus is controlled to use the signal supplied as the foreground image.

As a result of the preview of step SP408, when the effect set by the effect dialog 190 is a desired effect, the flow advances to the next step SP409.

In step SP409, the CPU 21 attaches the selected effect and the foreground event related to the effect to the timeline 95 in accordance with the operation of the editing operator. Since the method of attaching the effect to the timeline is different from the transition effect and the animation effect, the method of pasting the timeline of the transition effect and the method of pasting the timeline of the animation effect will be explained respectively.

First, a method of attaching a transition effect to a timeline will be described with reference to FIGS. 31A and 36B.

When the editing operator drags the icon 191b of the selected transition effect in the preferred pattern display unit 192 of the dialog 190 on the timeline 95 with the mouse 2D, the shadow of the icon as shown in FIG. 192X is displayed on the timeline 95.

Dropping the shadow 192X of this icon to the desired position on the effect line 135 of the timeline 95 sets the transition effect 192Y as shown in FIG. 31B.

Fig. 31B shows the image of "Heli-1" and the image of "Ship2" in the effect period shown by "Mix" when the transition from the event "Heli-1" to the event "Ship2". It shows mixing. That is, when performing a mix effect, the event called "Heli-1" is designated as a background image, and the event called "Ship2" is designated as a foreground image.

In this way, when the transition effect is set between events, the out point of the event designated as the background image is automatically extended by the transition time. For example, suppose that the out point of the event "Heli-1" designated as the background image is "00: 00: 05: 00" and the transition time of the mix effect 192Y is 2 seconds. The out point of the event "Heli-1" is automatically extended only 2 seconds, and becomes "00:00:07: 00".

When executing such a transition effect, in response to a control signal from the CPU 21 of the computer, the matrix switcher 3B of the editing processing apparatus 3 outputs a video signal of a material called "Heli-1" to the output terminal OUT9. The cross point is changed so as to be set as a signal S26 outputted from the reference signal) and set as a signal S24 outputted from the output terminal OUT 7 as a video signal of a raw material called "Ship2". In addition, in response to the control signal from the CPU 21 of the computer, the image processing unit of the editing processing apparatus 3 controls the mixer 54B to execute effects in accordance with the transition time set for the mixed effect and various effect parameters.

Next, with reference to FIGS. 32-35, the method of attaching an animation effect to a timeline is demonstrated. Since the method of attaching an animation effect on the timeline varies depending on the type of the effect and the method of setting the effect for the event, the description is divided into the following first and second cases.

The first case is a case of setting an effect for giving one event a special effect such as a zoom effect or a light spot. The first case will be described with reference to FIGS. 32A and 32B.

As with the operation of pasting the transition effect on the timeline, the editing operator drags the icon 191B of the selected animation effect in the preferred pattern display 192 of the dialog 190 on the timeline 95 by the mouse 2D. Then, the shadow 192E of the icon as shown in FIG. 32A is displayed on the timeline 95. When the shadow 192E of the icon is dropped at a desired position on the effect line 135 of the timeline 95, as shown in FIG. 32B, an animation effect 192F such as a special effect is set for the event "002". do.

In addition, when executing the animation effect as shown in FIG. 32B, in response to a control signal from the CPU 21 of the computer 2, the matrix switcher 3B of the editing processing apparatus 3 generates the event " 002 ". The intersection point is switched so as to set a video signal of a raw material as a signal S26 output from the output terminal OUT9. In addition, in response to the control signal from the CPU 21 of the computer, the image processing unit 3B of the editing processing apparatus 3 executes the effect according to the transition time set in the change effect and various effect parameters. 53).

The second case is a case of setting an effect for inserting an event having an effect on a certain event, such as a picture-in-picture effect. In order to explain the second case, "When setting the effect and clip at the same time" as follows, "When the effect to be attached first is the same length as the clip to attach later" and "The clip to attach later, the same length as the effect Will be described in detail.

First, the case where the effect and the clip are set at the same time will be described with reference to FIGS. 33A and 33B.

First, when the editing operator drags the clip card 179 displayed in the log window onto the timeline with the mouse 2D, the shape 192G of the icon as shown in FIG. 33A is displayed on the timeline 95. When the shape 192G of the icon is dropped at the desired position of the overlay video line 136, the event " 007 " dragged and dropped from the log window 93 is added to the overlay video line 136 as shown in Fig. 33B. Attached. At the same time, the effect currently set in the effect setting dialog 190 is automatically attached to the effect line 135. In addition, a period corresponding to the period of the event "007" attached to the overlay video line 136 is set as the period of the effect.

In this way, as long as the desired event is attached to the overlay video line 136, the effect is automatically set on the effect line 135 of the timeline, thereby further improving operability.

When executing the animation effect as shown in FIG. 33B, in response to the control signal from the CPU21 of the computer 2, the matrix switcher unit 3B of the editing processing device 3 causes the video signal of the raw material of the event "002" to appear. Is set as the signal S26 output from the output terminal OUT 9, and the crossing point is changed so as to set the video signal of the same event "007" as the signal S24 output from the output terminal OUT7. In addition, in response to the control signal from the CPU 21 of the computer, the image processing unit 3B of the editing processing apparatus 3 executes the special effect block (to execute the effect according to the transition time set for the change effect and various effect parameters). 53).

Next, a case in which the pasted effect is the same length as the clip pasted later will be described with reference to FIGS. 34A and 34B.

First, as shown in Fig. 34B, the editing operator drags the icon 191B of the animation effect selected in the dialog 19O onto the effect line 135 of the timeline 95 with the mouse 2D, and then over the desired event. By dropping so as to attach the desired effect (192K) on the effect line 135.

Next, as shown in Fig. 34A, the editing operator drags the clip card 179 displayed in the log window onto the timeline with the mouse 2D. 33B, when the dragged clip card is dropped on the overlay video line 136 of the timeline, the desired event 192L is pasted to the overlay video line 136. As shown in FIG. The period of the effect 192K attached first is changed according to the period of the event 192L attached as the foreground image, and as a result, the effect line 135 has a period corresponding to the period of the event 192L attached later. An effect 192M is displayed. In other words, the transition period of the effect 192M is changed according to the duration of the event 192L attached later.

In this way, by automatically changing the duration of the attached effect first according to the duration of the event 192L attached as the foreground image, the editing operability can be improved because it is not necessary to reset the duration of the effect.

When the animation effect as shown in FIG. 34B is executed, in response to a control signal from the CPU 21 of the computer 2, the matrix switcher unit 3B of the editing processing apparatus 3 receives the raw material of the event "002". Video signal of the same event "002" is set as the signal S24 output from the output terminal OUT7, and the intersection point is changed so as to set the video signal of the same event "002" as the signal S26 output from the output terminal OUT9. . In addition, in response to a control signal from the CPU 21 of the computer, the image processing unit 3B of the editing processing apparatus 3 executes the switcher so as to execute effects in accordance with the transition time set for the picture-in-picture effect and various effect parameters. Block 52 is controlled.

Next, the case where the clip to be attached later is the same length as the effect of attaching it first will be described with reference to FIGS. 35A and 35B.

First, as shown in Fig. 35A, the editing operator drags the icon 191B of the animation effect selected in the dialog 190 on the effect line 135 of the timeline 95 with the mouse 2D, and then over the desired event. By dropping to make, the desired effect 1920 is attached over the effect line 135.

Next, the editing operator drags the clip card 179 displayed in the log window onto the timeline with the mouse 2D as shown in Fig. 35A. Then, as shown in Fig. 35B, when the dragged clip card is dropped to overlap the effect 1920 to which the effect line 135 of the timeline is pasted, the event 192P is attached to the overlay video line 136. The duration of the event 192N attached as the foreground image is changed according to the duration of the first attached effect 1920, and as a result, the overlay video line 136 corresponds to the duration of the first attached effect 1920. An event 192P with a duration is displayed. In other words, the out point of the event 192P is changed so that the duration of the first attached effect 1920 matches the duration of the later attached event 192P.

In this way, the operation of changing the duration of the event can be omitted by making the first attached effect period coincide with the duration of the later attached event, thereby improving the edit operability.

When executing the animation effect as shown in FIG. 35B, in response to a control signal from the CPU 21 of the computer, the matrix switcher unit 3B of the editing processing apparatus 3 sends a video signal of the raw material of the event "006". Is set as the signal S26 output from the output terminal OUT9, and the intersection point is changed so as to set the video signal of the raw material "event" as the signal S24 output from the output terminal OUT7. In addition, in response to a control signal from the CPU 21 of the computer, the image processing unit of the editing processing apparatus 3 executes the special effect block 53 so as to execute effects in accordance with the transition time set for the change effect and various effect parameters. To control.

Next, a method of attaching an effect to the timeline 95 using the timeline 95 will be described with reference to FIGS. 36A and 36B.

First, when the editing operator clicks and inputs the TL button 126 of the viewer window 92, the operator changes to the timeline control mode. The timeline control mode is a control mode in which the timeline 95 and the viewer window 92 are temporally associated with each other. Therefore, the video image corresponding to the time code of the display position of the current line 139 in the time line 95 is displayed in the viewer 106 of the viewer window 92.

When the editing operator manipulates the slider portion 120 of the device control portion 96 to retrieve the desired frame of the file, the current line 139 moves over the time line 95 accordingly. That is, when the editing operator performs device control such as playback or jog driving, the computer 2 causes the graphic user interface 90 to be displayed on the monitor 2D so that the current line 139 moves right over the timeline 95. ) And control each source device so that a video image is displayed in the viewer 106 of the viewer window 92 in conjunction with this.

Next, when the editing operator clicks the mark in button 115 at the desired position while viewing the video image displayed in the viewer 106 of the viewer window 92, the CPU 21 causes the CPU 21 to press when the mark in button 115 is pressed. A flag 166C and a mark line 166C indicating an in-point point are displayed at the position where the current line 139 is present on the timeline 95.

In the timing at which the point is marked, the point display field 110 on the viewer window 92 indicates that the point is marked in the timeline control mode, not in the stamp picture of the frame displayed in the viewer 106. An image such as flag 116C is displayed for the purpose of exiting.

When the editing operator operates the slider 120 of the device controller 96 to search for a file and clicks the mark out button 116 at a desired position, the CPU 21 presses the mark out button 116. On the timeline 95, a flag 166B and a mark line 166D indicating an out point point are displayed at the position where the current line 139 is present.

In the timing at which the out point is marked, the out point display field 112 on the viewer window 92 indicates that the out point is marked in the timeline control mode, not in the stamp picture of the frame displayed in the viewer 106. An image, such as flag 116D, is displayed to bet.

Next, as shown in FIG. 36B, the editing operator drags the desired clip card 179 from the clip card 179 of the log window 93 with the mouse 2D, and sets the mark line 166C of the set point. ) And the overlay video line 136 between the mark line 166D of the out point. As a result, an event dropped from the log window 93 is inserted between the mark line 166C and the mark line 166D on the overlay video line 136. 36B, the effect set in step SP407 is automatically inserted between the mark line 166C and the mark line 166D on the effect line 135. As shown in FIG.

If the duration of the clip dropped from the log window 93 and the duration defined by the mark line 166C and the mark line 166D are different, they are defined by the mark line 166C and the mark line 166D. Duration is prioritized. That is, the mark line 166C and the mark line 166D by correcting the time code of the out point of the clip dropped from the log window 93 in accordance with the duration defined by the mark line 166C and the mark line 166D. It is possible to match the duration of the clip dropped from the log window 93 to the duration defined by.

In addition, although an example of attaching an event to the overlay video line 136 has been described with reference to FIGS. 36A and 36B, the clip can also be attached to other lines (server audio line 134 and voice over line 138A, 138B). .

By the above operation and control, it is possible to set the section in which the foreground event relating to the effect and the effect is inserted on the timeline 95 while looking at the position of the background event already attached to the timeline on the timeline. In addition, effects and foreground events can be attached at arbitrary positions and periods, regardless of edit points such as in and out points of background events already attached on the timeline.

When the process of attaching the effect of step SP409 and the process of attaching the foreground event are finished, the process proceeds to the next step SP410.

In step SP410, under the control of the editing operator, the CPU 21 of the computer 2 executes a preview process of previewing the program created on the timeline 95. Specifically, when the editing operator clicks the preview button "PVW" 123B, the preview is started from the position of the current line 139 of the timeline 95. During the preview, video and audio corresponding to the program on the timeline 95 are reproduced from the local memory device 8 under the control of the computer 2. In addition, the editing processing apparatus 3 processes the supplied video material and audio material so that video processing and audio processing corresponding to the program on the timeline 95 are performed under the control of the computer 2. Output The CPU 21 of the computer 2 controls the display controller 23 as displayed in the viewer 106 of the viewer window 92, and at the same time the timeline 95 corresponds to the displayed image. Display controller 23 is controlled to vary the position of current line 139 on timeline 95.

Since the current line 139 is moving to correspond to the image displayed in the viewer 106 of the viewer window 92, the editing operator looks at the image displayed in the viewer 106 of the viewer window 92. The image displayed on the viewer 106 can be easily identified at which position of the program created on the timeline 95, and at the same time, to which position of the program created on the timeline 95, the viewing is finished. I can figure it out.

Next, the process of the editing processing apparatus 3 at the time of preview is demonstrated in detail with reference to FIG. 37A to 37C are diagrams showing the shape of a timeline at a timing when previewing is executed.

37 shows an example in which the transition effect "Wipe" is specified between the event E0 and the event E1. 37A to 37C are diagrams each showing the shape of the timeline at any timing during the preview execution.

37A shows a state in which the event E0 is reproduced before the effect is executed. At this time, the computer 2 controls the editing processing apparatus 3 to process the event E0 as a background event. The case where the signal of the event E0 is supplied to the input terminal IN4 of the matrix switcher part 3B of the edit processing apparatus 3 as the output signal S13A from the local memory device, for example, edit at this time The control of the processing apparatus 3 is demonstrated in more detail.

The system control unit 3A of the editing processing apparatus 3 first controls the matrix switcher unit 3B to actively perform the intersection point P49 for connecting the input terminal IN4 and the output terminal OUT9. As a result, the video signal S13A of the event E0 supplied to the input terminal IN4 is output from the output terminal OUT9 as the output video signal S26 and supplied to the image processing unit 3C.

The output signal S26 output from the output terminal OUT9 is supplied to the demultiplexer 51D of the image processing section 3C. The demultiplexer 51D extracts only the digital video signal from the payload portion of the data in the SDI format. In the image processing unit 3C, the digital video signal is output as the output video signal S32 through the switcher block 52, the special effect block 53, and the mixer block 54. As shown in FIG.

The digital video signal S32 output from the image processing section 3C is supplied to the input terminal IN10 of the matrix switcher section 3B again. The CPU 21 controls the matrix switcher unit 3B to activate the intersection point P105 for connecting the input terminal IN10 and the output terminal OUT 5 through the system control unit 3A of the editing processing apparatus 3. To control. As a result, the digital video signal S32 supplied to the input terminal IN10 is output from the output terminal OUT 5 to the computer 2 via the output processor 46 as the digital video signal S2.

The digital video signal S2 output from the editing processing apparatus 3 is supplied to the video processor 22 of the computer 2 and displayed on the computer monitor 2B viewer window 92 via the display controller 23. . As a result, the video signal of the event E0 reproduced from the local storage device 8 as the reproduction signal S13A is displayed in the viewer window.

FIG. 37B shows a state in which the preview has progressed from the state shown in FIG. 37A, and shows the timing at which the transition effect "Wipe" set between the event E0 and the event E1 starts to be executed.

At this timing, the computer 2 controls the editing processing apparatus 3 to process the event E0 as a background event and to process the event E1 as a foreground event. As described above, the signal of the event E0 is supplied as an output signal S13A from the local memory device to the input terminal IN4 of the matrix switcher portion 3B of the editing processing apparatus 3, and the event E1 Is an example of a case in which the signal is supplied to the input terminal IN5 of the matrix switcher section 3B of the editing processing apparatus 3 as an output signal S13B from the local memory device. Will be described in more detail.

Since the matrix switcher unit 3B of the editing processing apparatus 3 supplies the video signal of the event E0 to the image processing apparatus 3C, it is not necessary to control the intersection point. This is because the editing processing apparatus 3 is already controlled by the computer 2 so as to process the event E0 as a background event. Therefore, when the intersection point P49 of the matrix switcher unit 3B is made active, the input terminal is activated. This is because the video signal S13A of the event E0 supplied to IN4 is output from the output terminal OUT9 to the image processing unit 3C as the output video signal S26.

The video signal of the event E0 supplied as the output signal S26 to the image processing unit 3C is supplied to the video signal processing circuit 52F of the switcher block 52 through the demultiplexer 51D. The video signal processing circuit 52E performs a process of performing a wipe effect on the supplied video signal of the event E0 based on the wipe control signal from the wipe signal generation circuit 52B. The video signal of the wiped event E0 is supplied to the mixer circuit 54B.

Further, the key signal related to the event E0 is the matrix switcher part, like the routing process in the matrix switcher part 3B to the video signal of the event E0 and the wipe process in the video signal processing circuit 52F. The routing process in (3B) is performed, and the wipe process in the key signal processing circuit 52D is performed.

On the other hand, in order to supply the video signal of the event E1 reproduced from the local storage device 8 to the computer 2, the system control section 3A of the editing processing device 3 first inputs the input terminal IN5 and the output terminal. The matrix switcher section 3B is controlled to activate the crossing point P57 for connecting OUT7. As a result, the video signal S13B of the event E1 supplied to the input terminal IN5 is output from the output terminal OUT7 as the output video signal S24 and supplied to the image processing unit 3C. The output signal S26 output from the output terminal OUT7 is supplied to the demultiplexer 51B of the image processing section 3C. The video signal of the event E1 output from the demultiplexer 51B is supplied to the video signal processing circuit 52E of the switcher block 52. The video signal processing circuit 52E performs a process of performing a wipe effect on the supplied video signal of the event E1 based on the wipe control signal from the wipe signal generation circuit 52A. The video signal of the wiped event E1 is supplied to the mixer circuit 54B.

The key signal related to the event E1 is the same as the routing switch in the matrix switcher unit 3B for the video signal of the event E1 and the wipe process in the video signal processing circuit 52E. The routing process in 3B) is performed, and the wipe process in the key signal processing circuit 52C is performed.

The mixer circuit 54B mixes the video signal of the wiped event E1 and the video signal of the wiped event E0, and outputs the mixed signal as an output signal S32.

The digital video signal S32 output from the image processing section 3C is supplied to the computer 2 again via the matrix switcher section 3B. As a result, the video of the event E0 reproduced from the local memory device 8 and the wipe image generated based on the video of the event E1 are displayed in the viewer window 92.

FIG. 37C shows a state where the preview has progressed again from the state shown in FIG. 37B, and shows the timing when the transition effect "wipe" set between the event E0 and the event E1 ends.

When the wiping process is being performed, the computer 2 processes the event E0 as a background event and processes the event E1 as a foreground event, but at the timing at which the wipe process ends, the computer 2 processes the event E0. Instead, the editing processing apparatus 3 is controlled to process the event E1 as a background event. The control of the editing processing apparatus 3 at this time will be described in more detail.

First, since the matrix switcher 3B of the editing processing apparatus 3 does not need to supply the video signal of the event E0 to the image processing apparatus 3C and the computer 2, the input terminal IN4 which has been active so far The crossing point P49 for connecting the output terminal OUT9 is changed to active. As a result, the video signal S13A of the event E0 supplied to the input terminal IN4 is not output from the output terminal OUT9. On the other hand, since the event E1 must be processed as the background video instead of the event E0, the matrix switcher part 3B of the editing processing apparatus 3 inputs the input terminal IN5 to which the signal of the event E1 is supplied. And cross point P59 for connecting to output terminal OUT9 are made active. As a result, the video signal S13B of the event E1 supplied to the input terminal IN5 is output from the output terminal OUT9.

In this way, since the intersection point of the matrix switcher portion 3B of the editing processing apparatus 3 is automatically controlled so that an appropriate signal is output in accordance with the execution timing of the effect, the editing operator creates a desired program on the timeline 95. The video program corresponding to the created program can be automatically created as long as it is.

If the program is not satisfied as a result of the preview processing in step SP410, if modification is necessary, the process proceeds to the next step SP411. If the program is satisfied, the process proceeds to the next step SP412.

In step SP411, the CPU 21 corrects the events and effects attached to the timeline 95 in accordance with the operation of the editing operator.

When modifying an event First, in the timeline 95, an event requiring correction is double-clicked with the mouse 2D. The CPU 21 reproduces the double clicked event from the local memory device 8 and controls the local memory device 8 and the editing processing device 3 as displayed in the viewer window 92. In addition, the CPU 21 displays the video reproduced from the local storage device 8 in the viewer 106 of the viewer window 92, and simultaneously points in and out stamp pictures stored in the internal hard disk HDD. It displays on the image display part 110 and the out point image display part 120, respectively.

As in the case of creating a clip, if necessary, various parameters such as reset video and audio level of the in and out points are readjusted.

When the desired correction process ends and the editing operator clicks the ADD button 122A, the CPU 21 overwrites the information on the modified event with the information of the old event on the timeline 95 and at the same time the timeline 95 of the timeline 95. Change the display from an old event to a modified event.

In addition, when correcting an effect, first, in the timeline 95, the effect requiring correction is double-clicked with the mouse 2D. The CPU 21 opens the effect setting dialog 190 in which the double clicked effect is set.

In the same way as when the effects are set, the effect type transition time and change parameters are reset as necessary.

When the desired modification is finished and the effect setting dialog 190 is closed, the CPU 21 overwrites the information on the modified effect with the information of the old effect and at the same time changes the display of the timeline 95 from the old effect to the modified effect. do.

In step SP412, the CPU 21 creates a program list EDL according to the program created on the timeline 95, and records the EDL as a file in an EDL folder provided in the internal hard disk HDD.

In step SP412, the CPU 21 creates a completed video program according to the instruction of the editing operator. When the editing operator clicks the REC button 123D, the REC dialog shown in FIG. 38 opens. First, the editing operator selects a recording device for recording the completed video program from the local storage 8 VTR 7 and the on-air server 9 and inputs an appropriate file name. When the edit operator clicks the execute button " Execute, " the computer 2 selects the local storage device 8 and the edit processing device 3 in accordance with the program list EDL or the program on the timeline 95 as in the preview.
