Description

Signal processing device and signal processing method

The present invention relates to a signal processing apparatus and a signal processing method, and is suitably applied to, for example, a news program production broadcasting system.

So far, as one of the news program production broadcasting systems, there is a system configured as shown in FIG.

The news program production broadcasting system 1 configured as described above includes first and second AV audio and video servers 2 and 3 for recording / playback of AV (audio and / or video) data on an array of hard disk drives (HDDs), A plurality of editing apparatuses 4A-4N, a system control unit 5 for controlling the entire system, and a data storage device 6 in which various kinds of data are stored. Then, the uncompressed or low-compressed audio video data D1A-D1N transmitted from the field collecting data for the article through the transmission circuit or reproduced from the data tape is supplied to the first AV server 2 through multiple channels. do.

In this respect, the first AV server 2 inputs the audio video data D1A-D1N of one of the multiple systems specified among the audio video data D1A-D1N to be supplied under the control of the system control unit 5 and Each of them is stored in a designated address position of the recording / reproducing unit as they are set in the file.

Audio and video data D1 of each file stored in the first AV server 2 can be continuously read for several files from the first AV server 2 using respective editing apparatuses 4A-4N, respectively. The images based on the read audio video data D1 can be displayed on the monitors of the editing devices 4A-4N, respectively.

In addition, the operator can define the editing execution order for producing the news video for broadcasting by editing the audio video data D1 and visually confirming the image monitor displayed on the editing apparatuses 4A-4N (hereinafter, such as The list may be referred to as an editing decision list EDL), and the EDL may be registered in the editing apparatuses 4A-4N and executed.

In fact, when executing the EDL, the editing apparatuses 4A-4N read the first AV server 2, and also read the necessary audio and video data D1 by editing based on the EDL, and again the second AV server 3 Audio video data (D2A-D2N) obtained by editing the processing for the "

At this time, the second AV server 3 captures the edited audio-video data D2A-D2N to be supplied under the control of the system control unit 5, sets those data to a file, and designates the address position of the recording / reproducing unit. Store in

Thereafter, the audio and video data D2A-D2N stored in the second AV server 3 is reproduced and decompressed at a necessary time based on the management information in the data storage device 6, and is broadcasted to a broadcast device (not shown). And is broadcast through the broadcast apparatus under the control of the system control unit 5.

Therefore, in the news program production broadcasting system 1, the audio and video data D1A-D1N obtained by collecting the data can be edited according to a desired state and broadcasted at a predetermined time.

However, according to the above-described news program production broadcasting system 1, if the contents of the audio video data D1A-D1N obtained by collecting data and registered in the first AV server 2 can be confirmed by many people, EDL can be formed by more people, taking into account that the efficiency of news program production and the characteristics of news videos obtained by editing can be further improved.

However, according to the news program production broadcasting system 1 thus configured, the number of editing apparatuses 4A-4N that can be connected to the first AV server 2 is determined by the data transmission capacity of the first AV server 2. Since it can be determined, it is difficult to systematically increase the number of editing apparatuses 4A-4N.

In addition, in the case where such a system is realized, it has been considered that the editing operation can be executed more efficiently when automatic editing based on EDL is executed in the editing executor. However, depending on the editing executor that can be considered at present, the EDL should be assigned to the editing executor taking into account the order of the editing process, which causes difficulties by the operator, thereby causing problems in further improving the efficiency of the editing operation. Let's do it. In addition, EDL can handle editing processes such as audio split editing, voice over editing, or image effect editing (e.g., mosaic, page turn and wipe). In the case of inclusion, the operator has to perform a complex task, such as controlling the audio video data input to the edit executor, which causes problems in further improving the efficiency of the edit operation.

Further, as a conventional news program production broadcasting system, there is an apparatus configured as shown in FIG. In comparison with the conventional news program production broadcasting system of Fig. 1, since the reference / reading devices 7A-7N are connected to the output side of the second AV server 3, the second AV server ( Audio video data D2A-D2N stored in 3) and an image based thereon may be displayed on a monitor. Therefore, the operator reads the audio video data D2A-D2N from the second AV server 3 using the reference / reading devices 7A-7N before it is transmitted to the broadcasting device, and reads an image based on the data. By displaying, the editing results of the news video can be visually checked before being actually broadcasted.

Therefore, in the news program production broadcasting system 1, the audio video data D1A-D1N obtained by the data collection can be edited in a desired state and broadcasted at a predetermined time.

However, in the news program production broadcasting system 1 thus constructed, since the system is quite large, each device is installed in a separate place, for example, each editing device 4A-4N It is installed in an editing room, and each reference / reading device 7A-7N is respectively installed in a sub-adjustment room.

Thus, in the event that program production staff and people work in related fields at a place other than the sub-control room, for example, if a program producer and a news draft producer want to reference and read an edited video, they When it is necessary to stop work, they have to go to the sub-control room and their work efficiency is greatly reduced. Therefore, in recent years, in order to obtain high efficiency, the need for increasing the number of reference / reading apparatuses 7A-7N and installing them in various places increases the need for checking video editing results in each place. It is becoming.

However, in such a news program production broadcasting system 1, the number of reference / reading apparatuses 7A-7N that can be connected to the second AV server 3 depends on the transmission capacity of the second AV server 3. As determined by, the number of reference / reading devices 7A-7N could not be easily increased.

In addition, there is an apparatus configured as shown in Fig. 3 as a conventional news program production broadcasting system 1. This apparatus has an audio booth 11 connected to the input means of the first AV server 2, and the telephone 12 and the tape recorder 13 connected to the editing apparatus 4N. It is different from the device shown in 1. In order to superimpose a voice such as a narration via the audio video data D1A-D1N, the audio data D11 is obtained using a microphone of the audio booth, which is the first AV server 2 such as an audio file. Are stored in. This audio file is registered in the data storage device 6 and, when edited simultaneously, is read by the editing devices 4A-4N and combined with the audio video data D1A-D1N.

In addition, the voice obtained by the telephone interview is supplied once to the editing apparatus 4A-4N as an external audio input of the editing apparatus 4A-4N after being recorded once via the telephone 12, and the audio and video data ( D1A-D1N).

In the field of news production of a broadcasting station, a correspondent (reporter) prepares a draft of a story for superimposing on audio video data D1A-D1N by using a communication terminal composed of a personal computer. Therefore, if the voice story by the draft story can be inputted according to the draft input when the draft is input into the communication terminal, the editing operation can be executed more easily.

An object of the present invention is to provide a signal processing apparatus and a signal processing method which can improve the efficiency of the program production work.

It is another object of the present invention to provide a signal processing apparatus that can more easily execute an editing operation in the case of combining audio with collected material consisting of video signals and / or audio signals.

(1) Configuration of news program production broadcasting system

Fig. 4 is an overall view of a news program production broadcasting system, which includes an off-line EDL forming system 22 for forming an EDL (Edit Decision List: a list in which edit execution order is defined), each of which is edited. Broadcast list forming system 23 for forming a list in which transmission time of audio and video data is defined (hereinafter referred to as an on-air list) and a news draft and an order of use of the draft, off-line EDL formation The on-line edit transmission system 24 for executing the edit processing based on the EDL formed in the system 22, the storage 25 for storing necessary audio video data, and the whole news program production broadcasting system 20 A system control unit 26 for controlling, an off-line EDL forming system 22, a broadcast list forming system, an on-line editing transmission system 24, a repository 25, and a system Control unit 26 is connected through a LAN (local area network) (27).

In such a news program production broadcasting system 20, data including audio and / or video data transmitted from a field collecting data or from a satellite communication circuit through a transmission circuit or reproduced from a data tape by a video tape recorder. D10 (hereinafter referred to as AV data) is supplied via multiple channels, the daily buffer 30 of the on-line editing transmission system 24 and the input buffer device 31 of the off-line EDL forming system 22. Is entered. In the following description, each AV data D10 is supplied under uncompressed or low compressed (e.g., Moving Picture Experts Group (MPEG) 2 4: 2: 2P @ ML (ITU-R recommendations) conditions). Assume

The daily server 30 is mainly composed of a recording / reproducing unit for recording and reproducing the AV data D10 on a non-linear accessible recording medium forming an array of HDDs, and a compression decompression unit represented by MPEG2, and enables high-speed data input / output. Then, the AV data D10 selected from the multiple AV data D10 to be supplied under the control of the system control unit 26 is captured and set in a file and stored at the address position selected in the recording / reproducing unit. The AV data D10 input to the daily server 30 is actually multiple inputs, but for simplicity of explanation, Fig. 4 shows the case of one input. Of course, we can see that there is nothing wrong with one input.

On the other hand, the input buffer device 31 can continuously capture AV data D10 of the same system as the daily server 30 from the respective AV data D10 to be supplied. When the captured AV data D10 is high-speed data, the input buffer device 31 not only time-divisions into multiple channels, but also expands each channel of the AV data D10 in real time, respectively. The AV data D11 of the result of the transmission is transmitted to the encoder unit 32, respectively. When the captured AV data D10 is real-time speed data, the AV data D10 is directly transmitted to the encoder unit 32.

The encoder unit 32 continuously captures each AV data D11 (or D10) to be supplied, and captures the captured data using a prescribed compression system such as a Joint Photographic Experts Group (JPEG) system. The high compression encoding is performed at about 2 Mbps, and the resulting high compression coded data d12 is transmitted to the clip server 33.

The clip server 33 has a structure substantially the same as that of the daily server 30, and includes a recording / playing unit for recording / reproducing high compression coded data D12 on a non-linear accessible recording medium forming an array of HDDs. Under the control of the system control unit 26, the input high compression coded data D12 is continuously captured and set in a file, and stored in an address position selected in the recording / reproducing unit.

Then, each file data (high compression coded data D12) stored in the clip server 33 can be read in a plurality of EDL forming apparatuses 34A-34N each connected to the clip server 33.

In fact, when forming an EDL, if a command for reading a desired file is input by an operator, each of the EDL forming apparatuses 34A-34N is connected to the system control unit 26 via the clip server 33 and the LAN 27. ) Is continuously accessed, and the high compression coded data D12 of the file corresponding to the clip server 33 is continuously read.

In addition, the EDL forming apparatuses 34A-34N decode the high compression coded data D12 read out from the clip server 33, and display an image of the result based on the AV data on the monitor.

At this point, the operator controls the clip server 33 via the EDL forming apparatus 34A-34N to perform the desired operation (eg, play, rewind or fast advance) by the clip server 33. In addition, at this point, the operator visually confirms the image displayed on the monitor of the EDL forming apparatus 34A-34N, for example, in-points and out-pointers. EDL can be formed by entering various pieces of information needed to edit points.

In addition, the EDL forming apparatus 34A-34N reads and decodes the corresponding high compression coded data D20 from the clip server 33 based on the formed EDL, and can edit the AV data of the result based on the EDL, and can be edited. The results can be displayed on the monitor, whereby the operator can check the edited results based on the EDL.

Thereafter, the EDL data (hereinafter, referred to as EDL data) formed in the EDL forming apparatuses 34A-34N are successively transferred from the EDL forming apparatus 34A-34N to the system control unit (through the clip server 33 and the LAN 27). 26, and is registered as a database in the external storage device 35 under the control of the system control unit 26.

On the other hand, the broadcast list forming system 23 includes an external storage device 37 for storing various types of data such as a broadcast list and used as a database, and a database management device for managing data stored in the external storage device 35 ( 36, a plurality of personal computers 39A-39N, each connected via a database management device 36 and a network 38, each item of each news program to be read by the broadcast list and the announcer, It may be formed using personal computers 39A-39N.

Then, the respective data for the broadcast list and the draft thus formed are registered as a database of the external storage device 37 under the control of the database management device 36, and the data of the broadcast list (hereinafter referred to as broadcast list data) is It is supplied to the system control unit 26 via the LAN 27, and is registered in the external storage device 35 as a database.

Then, the system control unit 26 controls the on-line edit transmission system based on the broadcast list data and the EDL data registered in the external storage device 35.

In particular, the system control unit 26 always monitors the operating status of the EDL executor 40A-40N having a plurality of editing apparatuses connected to the daily server 30 of the on-line editing transmission system 24, and the EDL When one of the executors 40A-40N finishes the editing process, the EDL data stored in the external storage device 35 prior to the broadcast is read based on the broadcast list data, and the LAN 27 ) To the EDL executor 40A-40N.

The EDL executors 40A-40N control the daily server 30 based on the EDL data to be supplied from the system control unit 26, and are stored by the daily server 30 in the uncompressed stored in the daily server 30. Alternatively, necessary AV data D10 is continuously read from the low-compressed AV data D10. In addition, when the AV data D10 is low compressed, the EDL executors 40A-40N decode the data, and then edit the AV data D10 in a specified state based on the supplied EDL data. The resulting AV data (D13A-D13C) are transmitted to the broadcast server 41, respectively.

In this regard, the manually operated editing device 42 is connected to the daily server 30, and the operator reads the AV data D10 stored in the daily server 30 using the editing device 42, and the AV. Data D10 can be edited. The resulting AV data D13D is transmitted to the broadcast server 41.

The broadcast server 41 includes a recording / reproducing unit for recording or playing back the edited AV data D13A-D13D on non-linearly accessible recording media such as HDD and MO, and is input under the control of the system control unit 26. The captured AV data (D13A-D13D) are continuously captured and stored in the address position designated on the recording medium.

Then, the transmission time of each file data (the edited AV data D13A-D13D) stored in the broadcast server 41 is connected to the LAN 27 based on the broadcast data stored in the external storage device 35. Controlled by 49 and, upon reaching a designated time, read from the broadcast server 41 under the control of the system control unit 26, and transmit it to the broadcast device of the next stage (not shown), and in the news program Video material and audio material to be broadcasted are transmitted.

Therefore, in the news program production broadcasting system 20, the editing process is based on the EDL formed in the off-line EDL forming system 22, and the uncompressed or low-compressed AV data in the on-line editing transmission system 24 ( The resultant AV data D13A-D13D, which is executed using D10), can be transmitted to the broadcast apparatus based on the broadcast list, and news audio and video edited in a designated state can be broadcast at a specified time. .

In addition to the above, in the case of the news program production broadcasting system 20, a near line server 43 having a recording / reproducing unit for recording and / or playing back AV data on a recording medium is inexpensive.

D13A-D13D are transmitted to the near line server 43, and they may be stored in the near line server 43.

In addition, the AV data D10 and D13A-D13D stored in the near line server 43 can be transmitted to the daily server 30 under the control of the system control unit 26, whereby the on-line editing transmission system 24 The storage capacity of the input stage can be increased without increasing the storage capacity of the daily server 30 having a large number of expensive and non-linear accessible recording media.

Moreover, the near line server 43 is connected to the cassette autochanger 44 of the storage 25 via a prescribed interface such as SCSI (small computer interface), and under the control of the system control unit 26, the storage 25 AV data (D10, D13A-D13D) of the near line server 43 is transferred to the cassette automatic exchanger 44 of the < RTI ID = 0.0 > and < / RTI > (D10, D13A-D13D) can be recorded. Therefore, in the news program production broadcasting system 20, necessary AV data can be stored as material.

In this regard, various management data relating to the contents of the AV data D10 and D13A-D13D are supplied from the system control unit 26 to the database management device 45 provided to the storage 25 via the LAN 27. These management data are then provided to the external storage device 46 and stored as a database under the control of the database management device 45.

Further, at this point in time, under the control of the system control unit 26, the draft data corresponding to the AV data is stored from the database management device 36 of the broadcast list data forming system 23 via the LAN 27 and stored in the storage 25. The draft data can be transmitted to the database management device 45, and the draft data can be registered in the database of the external storage device 46 under the control of the database management device 45.

In addition, the AV data D10 and D13A-D13D recorded on a recording medium such as a magnetic tape stored in the storage 25 can be reproduced by the cassette auto changer 44, and the off-line EDL forming system 22 The input buffer device 31 and the daily server 30 of the on-line edit transfer system 24.

(12) Schedule management by system control unit

The following describes schedule management of editing processing executed by the system control unit 26. This schedule management is divided into two types. One is to assign the registered EDL to the EDL executor, and the other is to assign server output to the EDL executor. These points will be described next in succession with reference to the drawings. In the following description, the four EDL executors 40A-40N provided are connected to the daily server 30.

First, the internal configuration of the daily server 30 will be described with reference to FIG. In Fig. 17, corresponding parts of Fig. 4 are provided with the same reference numerals, and 30 shows the daily server as a whole, which largely includes the control unit 30A, the server storage 30E, and the router 30C. do.

The control unit 30A is a control means for controlling the operation of the daily server 30, and the data recording command and the server output allocation command from the system control unit 26 or the data reproduction from the EDL executor 40A-40D. Receiving the commands, and in accordance with those commands, the control unit 30A controls the operations of the server storage 30E and the router 30C. For example, to the server storage unit 30E, the control signal S50 is output in accordance with the data recording command from the system control unit 26, so that the control unit 30A performs the recording operation of the AV data D10. Instruct. Further, to the server storage unit 30E, the control signal S50 is output in accordance with the data reproducing command from the EDL executors 40A-40D to instruct the reproducing operation of the AV data D10. Further, the control signal S50 is output to the router 30C to instruct the switching operation of the signal route in response to the server output allocation command from the system control unit 26.

The server storage unit 30E is a recording / playing unit having a recording medium composed of an array of several hard disks, and receives the control signal S50 from the control unit 30A, and inputs AV data ( D10). In addition, the server storage unit 30E receives the control signal S50 from the control unit 30A, reads a desired portion of the AV data D10 from the recording medium, and stores the AV data D10 (or D10B-D10F). Output as In the example shown in Fig. 2, the server storage unit 30E has six output ports, and six kinds of AV data D10A-D10F can be reproduced simultaneously and output separately. The six output ports of the server storage unit 30E are connected to the input terminals IN1-IN6 of the router 30C, respectively, and the reproduced AV data D10A-D10F can be input to the router 30C.

The router 30C is a signal route switching means having several signal routes inside, and selects a desired signal from the various signal routes to receive the control signal S51 from the control unit 30A, thereby providing input terminals IN1-IN6. The AV data D10A-D10F inputted to the output terminal is output to the desired output terminals OUT1-OUT8. In particular, in the router 30C, the input signal route connected to the input terminals IN1-IN6 and the output signal route connected to the output terminals OUT1-OUT8 are arranged in a matrix, and the desired input signal route and the desired output signal are arranged in a matrix. The route may be connected at the intersection of the input signal route and the output signal route. The AV data D10A-D10F input to the input terminals IN1-IN6 may be output to the desired output terminals OUT1-OUT8.

The output terminals OUT1-OUT8 of the router 30C are also output to the output terminals of the daily server 30, and in the example shown in Fig. 2, among the output terminals OUT1-OUT8, the output terminals OUT1 and OUT8 are output. OUT2 is connected to EDL executor 40A, output terminals OUT3 and OUT4 are connected to EDL executor 40B, output terminals OUT5 and OUT6 are connected to executor 40C, and output terminals OUT7 and OUT8 is connected to the executor 40D.

Thus, if the signal route is controlled by the router 30C as described above, for example, as shown in Fig. 17, the two output ports of the server storage 30E are connected to the EDL executor 40A. AV data D10A and D10B can be supplied to the executor 40A, and one output port 1 of the server storage 30E is assigned to the EDL executor 40B, thereby providing AV data ( D10C may be supplied to the EDL executor 40B, and the output port of one (1) of the server storage unit 30E is allocated to the EDL executor 40C, so that the AV data D10D is stored in the EDL executor ( 40C), and assigns two (2) output ports of the server storage unit 30E to the EDL executor 40D so that the AV data D10E and D10F can be supplied to the EDL executor 40D. Can be. In this regard, the signal supply example shown by the dotted line is one example, and there may be another signal supply example.

The EDL executors 40A-40D edit the AV data reproduced from the daily server 30 based on the EDLs supplied from the system control unit 26, respectively, and execute an editing process of confirming the edit contents indicating the EDLs. The resultant AV data D13A-D13D are output to the broadcast server 41, respectively. In this case, the EDL executors 40A-40D are suitable for executing various kinds of editing processing based on the EDL, and are typical editing processing, for example, voice division editing and full voice editing, or image signals as audio editing processing. There are image effects that apply special effects such as mosaics and page turns or wiping.

Moreover, the EDL executors 40A-40D, when two server outputs are simultaneously provided by a server output assignment executed under the control of the system control unit 26 (e.g., when two AV data are input), A / B When performing roll editing (for example, switch editing, insertion editing, or duplicate editing), a real-time editing process using 2 AV data input is executed. In addition, when one server output is allocated by the server output allocation executed under the control of the system control unit 26, in the case of executing A / B roll editing, the EDL executors 40A-40D are set to 2 in the proper order. By reading the AV data and storing the AV data first input to the buffer, and using the next input AV data and the stored AV data, the EDL executors 40A-40D execute the editing process rather than real time.

In this regard, in the news program production broadcasting system 20, the editing processing execution plan, for example, the schedule is controlled by the system control unit 26 as described above, and based on such management, Assign EDL registered to each EDL executor 40A-40D, and assign server output to each EDL executor 40A-40D. In the external storage device 35 connected to the system control unit 26, a program called an EDL execution management manager is stored, and when the system control unit 26 is started, the program is stored in the system control unit 26. Proceed to the memory area. Therefore, in the system control unit 26, when the EDL execution management manager is started, the schedule job of the editing process is executed by the EDL execution management manager.

The EDL execution management manager reads the execution priority information indicating the execution priority of the EDL registered by the operator in advance based on the broadcast list stored in the external storage device 35, the read broadcast list and the execution priority information. Register the registered EDLs arranged according to the output schedule time or execution order (this list indicates the final priority of the EDL execution). Next, the EDL execution management manager executes an EDL assignment task by allocating the EDL executors 40A-40 to the EDL execution schedule list according to the execution priority, and simultaneously executing the EDL assignment task. Are assigned to the EDL executors 40A-40D according to the edits shown by EDL and execution priority of the EDL. Then, after such an assignment operation, the EDL execution execution manager transmits the EDL data to the EDL executors 40A-40D, and the EDL executor 40A-40D executes the editing process.

At this point, the scheduling task to be executed by the system control unit 26 will be described in more detail with reference to the flowchart shown in Figs. 18-20. First, in the case of performing A / B editing, the scheduling process will be described with reference to FIG. In step SP2 coming from step SP1, the EDL will be formed by the EDL forming apparatuses 34A-34N in the next step SP3, when the formed EDL is registered in the external storage device 35 as a database. The system control unit 26 executes the schedule list forming job, and moves to next step SP4. In particular, in step SP4, the EDL execution manager reads the broadcast list and execution priority information from the external storage device 35 and according to the output schedule time or execution priority based on the broadcast list and the execution priority information. Arrange the registered EDLs and register them in the EDL execution schedule list.

Then, in the next step SP5, the EDL execution management manager captures the use state of each executor 40A-40D, and assigns the EDL executor 40A-40D to the EDL registered in the EDL execution schedule list. In the next step SP6, the EDL execution management manager captures the usage status of the server output (ie, the output port of the server storage 30E) and executes the EDL executor to perform A / B roll editing of the server output for two ports. Assign to

In the next step SP7, the EDL Execution Management Manager delivers the EDL data to each EDL Execution 40A-40N. Next, in the next step SP8, each EDL executor 40A-40N executes an editing process based on the delivered EDL data, and delivers the displayed AV data D13A-D13D to the broadcast server 41. . When each process is completed with this management, the system control unit 26 moves to the next step SP9 and ends the process.

Next, when executing the interruption process, the schedule process will be described with reference to FIG. First, in step SP11, if the EDL having a high priority is registered in the EDL execution schedule list while entering in step SP10 and all EDL executors 40A-40N are operating, the system control unit 26 Go to the next step SP12 and execute the abort process. In particular, in step SP12, the EDL execution management manager obtains the conditions of each EDL executor 40A-40D in operation, temporarily stops the operation of the EDL executor executing the EDL having the lowest priority, and temporarily Stop the execution of the EDL. Then, the EDL execution management manager sends the high priority EDL to the EDL executor, which causes the EDL executor to execute the EDL.

Next, in step SP13, the EDL execution management manager sends the suspended EDL to the empty EDL executor when each of the respective EDL executors completes the editing process, and when a blank occurs in the EDL executor, which is the EDL. To run With this management, each process is completed, the system control unit 26 moves to step SP14, and ends the interruption process.

Next, when the server output is not sufficient, the schedule process will be described with reference to FIG. First, when the EDL is formed by the EDL forming apparatuses 34A-34N at step SP21 coming in at step SP20, the EDL formed at the next step SP22 is registered in the external storage device 35 as a database, The system control unit 26 moves to the next step SP23 to execute the schedule list forming job. In particular, in step SP23, the EDL execution management manager reads the broadcast list and reads the execution priority information based on the broadcast list and the execution priority information from the external storage device 35 and outputs an output schedule time or execution priority. The registered EDLs are arranged according to the ranking, and they are registered in the EDL execution schedule list.

In step SP24, the EDL execution management manager captures the use conditions of each EDL executor 40A-40N, and assigns the EDL executors 40A-40D in the proper order to the EDL registered in the EDL execution schedule list. Next, in the next step SP25, the EDL execution management manager captures the occupation conditions of the server output (ie, the output port of the server storage 30E), and outputs the server output to each EDL executor 40A-40N. Allocate a server. In this case, if the server output is less than the number needed to run all the EDLs (that is, if the server output is insufficient), then the server output for 2 ports is assigned to the EDL executor to run the high priority EDL, and high priority. Run the EDL with in real time, assign the server output for a port to the EDL executor, or run an EDL with a lower priority. Then, it executes the low priority EDL. Thus, high priority EDLs can be processed quickly.

In step SP26, the EDL execution management manager checks the progress conditions of the editing process, and when the blank occurs in the server output, the execution of the EDL having a low priority is executed because the execution of the high priority EDL is completed. Allocate server output for two ports to the EDL executor, and switch the editing process to be executed in real time rather than in real time. Therefore, when each processing is completed, the system control unit 2 moves to the next step SP27 to complete the processing.

(13) operation of schedule management
