Abstract

PROBLEM TO BE SOLVED: To perform editing work improved in convenience with operability similar to a conventional linear editor while effectively utilizing a feature capable of non-linear editing. SOLUTION: In an A/V server, editing data are managed in the style of 'edit data page (page for short)' as a pair of IN point and OUT point in material data and data to be prepared and 'program' as the integration of this page. The page data are composed of the information of device names, file names and editing points of a recorder and a player for each page and these data for each page are integrated for all pages. A page number for identifying a page is expressed as continuous information such as serial numbers, assigned according to the order of preparation for the unit of a page. According to the time order of IN points in the data to be prepared, the A/V server changes only the page number and prepares the program in which the page data are rearranged.

Alternatively, a plurality of video / audio data recording / reproducing apparatuses for recording and / or reproducing (hereinafter, referred to as recording / reproducing) audio data (hereinafter, referred to as video / audio data) are provided.
There is an increasing demand for recording and reproducing audio data at the same time, and for reproducing while recording.
In order to satisfy such requirements, for example, a recording medium such as a hard disk (hereinafter, referred to as HD) or the like, which can be accessed randomly, is used, and a video server (or an AV server) that records and reproduces video and audio data on the recording medium. (Audi
o and / or Video) server) is becoming popular.

In general, a video server in a broadcasting station requires a high data transfer rate due to demands on image and sound quality of video / audio data to be recorded / reproduced on / from a recording medium. In order to record data, a recording medium needs to have a large capacity.

[0004] Therefore, an attempt has been made to increase the data transfer rate and increase the capacity by using a data recording / reproducing device including a plurality of HD devices capable of storing video / audio data and performing parallel processing. Attempts have been made to record parity data in the HD so that reliability can be ensured even if any HD device fails.

The data recording processing, data reproduction processing, and editing processing in the video server 200 will be described below.

The video server 200 records data input from the outside in the following manner.

In the video server 200, the data input to the input terminal 218 is input to the encoder 214 via the selector 213 provided in the data input / output unit 211 of the recording port 210, and is encoded into a predetermined format. The encoded data is recorded on port 2

The data recorded in 0 _n−3 , 310 _n−2 , 310 _n−1 and 310 _n is reproduced and output to the outside.

That is, in the video server 200, one of the reproduction ports 220, 230, 240
The HDD array 300 is accessed during the time slot allocated by the time slot generation circuit,
It requests the D array 300 to reproduce data. H
In the DD array 300, the video data writing / reading processing unit 302 includes the HDDs 310 ₁ , 310 ₂ ,.
The data and parity data divided and recorded into 10 _n−3 and 310 _n−2 are read, the divided data is unified, and error detection and error correction are performed based on the parity data. Play the data. Also, the audio data write / read processing unit 303

Play audio data from the DD. The reproduced video / audio data is buffered in the buffer 301,
The data is read and transferred via the data bus 320 to the reproduction port that has issued the reproduction request.

Here, assuming that the reproduction port 220 has made a reproduction request, for example, the HDD array 300
Is output to the buffer 223 provided in the data management unit 221 via the data bus 320. The data input to the buffer 223 is buffered by the buffer 223 and then converted to serial data by the P / S 224. The serial data is input to a decoder 226 provided in the data input / output unit 222, decoded, supplied to an output terminal 228 via a selector 227, and output to the outside.

Also, such a video server 200

DD 310 ₁ , 310 ₂ ,..., 310 _n-3 , 31
The data reproduced from 0 _n-2 , 310 _n-1 and 310 _n can be edited.

For example, when editing data input from the outside via the input terminal 218, the video server 2
00 inputs data to the editing unit 251 of the editing manager 250 via the selector 213 provided in the data input / output unit 211 of the recording port 210. Also, H
DD 310 ₁ , 310 ₂ ,..., 310 _n-3 , 31
When editing the data reproduced from 0 _{n -2} , 310 _n-1 , 310 _n , the video server 200 sends the data to the editing unit via the selector provided in the data input / output unit of the reproduction port that reproduced the data. 251 is input with data. Editing part 25

The editing process is performed using the video effector 260 as needed.

The editing unit 251 sends the edited data to the recording port 210 and the reproduction ports 220 and 23.
0,240.

For example, the editing unit 251 sets the recording port 210
If the data is output to the video server 200,
By performing the same as the above-described recording process processing, data _{HDD310 1, 310 2, ···,} 310 n-3, 3
Recorded in _{10 n-2, 310 n-} 1, 310 n. When the editing unit 251 outputs data to the playback ports 220, 230, 240, the video server 200 outputs the output terminals 228, 238 of the playback ports 220, 230, 240.
248 outputs data to the outside.

Further, the video server 200 can perform so-called non-linear non-destructive editing for retaining information such as an editing point without outputting edited data.
Therefore, the video server 200 is characterized in that it is possible to perform post-adjustment of editing points, which is difficult with a device that edits each cut, such as a so-called linear editing device that has been conventionally used. That is, the video server 200 sets H corresponding to the IN point and the OUT point of the material data and the created data.

In such a video server 200, a GUI (Graphical User) using a timeline is used so that the user can intuitively perform editing work.
Interfece). Video server 20
0, the control panel 2
The user performs an operation necessary for editing data by using 70.
At this time, the control panel 270 graphically displays various information necessary for data editing on the display unit. The user edits the data based on the graphical information displayed on the display unit of the control panel 270.

For example, HDDs 310 ₁ , 310 ₂ ,.
In the case of rearranging and reproducing a plurality of material data recorded in 310 _n-3 , 310 _n-2 , 310 _{n- 1} and 310 _n , the user is connected to, for example, an A / V server. Using a mouse (not shown) or the like, a graphic indicating desired material data displayed on the display unit of the control panel 270 is dragged and pasted on a desired time portion on the graphic indicating the timeline. Video server 200
A series of material data arranged on the timeline in this way is reproduced in the order of time.

[0053]

By the way, in a so-called linear editing apparatus which has been used in the past, the time indicating the IN point and the OUT point of the material data and the I time of the created data have been described.
The edit point information such as the time indicating the N point and the OUT point is represented by a numerical value, and the user can use the UI on which the character information is displayed.
(User Interfece), editing was done for each cut.

However, the video server 20 described above
In editing using the GUI at 0, a graphic is mainly displayed on the display unit of the control panel 270 as described above, so that the user performs an editing operation based on this graphical information. .

Therefore, like the video server 200,
Editing by the GUI to help the user intuitively perform the editing work is difficult for a user who is familiar with the conventional linear editing apparatus in terms of the speed of the editing work and the ease of learning the operation method. It was rather inconvenient.

For example, it is possible to perform so-called EDL (Edit Decision List) by performing off-line editing using an inexpensive linear editing apparatus capable of outputting only low-resolution video, and then perform on-line editing using an expensive editing apparatus. However, in this case, editing was not actively performed using the created EDL.

As described above, in the conventional nonlinear editing apparatus and linear editing apparatus such as the video server 200, further improvement in the convenience of the editing work is desired.

The present invention has been made in view of such circumstances, and has the same operability and convenience as a conventional linear editing apparatus, while taking advantage of the feature that a conventional video server allows non-linear editing. An object of the present invention is to provide an editing apparatus, a data recording / reproducing apparatus, and an editing information creating method capable of performing excellent editing work.

A display unit for displaying information, an input operation unit for inputting related information, and a page data creation order for each page data that is edit information in page units created according to the operation content of the input operation unit. Edit list creation means for creating edit list information by allocating continuous identification information according to the edit data. The edit list creation means edits creation data created by editing material data described in page data.

In the A / V server 1, once the recorder device and the player device are designated in this manner, when the reproduction designation switch 153 is subsequently pressed, for example, the port designated by the player is changed to the port designated by the player. Here, the reproduction port 20 is automatically selected, and becomes a controllable state as the current port.

Subsequently, the A / V server 1 creates a program in steps S4 to S8. First, in the A / V server 1, step S4
In, an edit point is set. At this time, in the A / V server 1, when the user presses the mode switch 164, the mode is switched to the material mode, and material data to be used for editing is loaded into the reproduction port 20. At this time, the display unit 1 of the control panel 80
Reference numeral 80 designates a playback port 20 in the source material name display section 185.
, The name of the file opened is displayed, and a predetermined name is displayed on the destination material name display section 187. The name displayed on the destination material name display section 187 can be changed later to an arbitrary name. If the material data has already been loaded into the reproduction port 20, there is no need to perform this procedure.

Thereafter, in the A / V server 1, the user presses the mode switch 164 again to shift to the edit mode, and presses the reproduction designation switch 153 to set the current port to the reproduction port 20. At this time, the display section 180 of the control panel 80 displays the current port display section 181 as shown in FIG.
“P1” indicating 0 is displayed, and the name of the file opened by the reproduction port 20 is displayed in the current port material name display section 182.

Then, in the A / V server 1, an editing point of the material data opened at the reproduction port 20 is set. The editing point is set using, for example, one of the following four methods.

As a first method, the user searches the point to be set as the IN point by rotating the search dial 170, and the image of the point is displayed on the IN point stamp picture display section 193. By pressing the IN point designation switch 160 to set the IN point, the user searches the point to be set as the OUT point by rotating the search dial 170, and the image of the point is displayed on the OUT point stamp picture display section 194. In the state,
There is a method of setting the OUT point by pressing the OUT point designation switch 161.

As a second method, the user searches the point to be set as the IN point by rotating the search dial 170, and the image of the point is displayed on the IN point stamp picture display section 193. The IN point display section 18 is operated by the rotary encoder 171 for cursor operation.
The user moves the cursor to the position No. 9 and presses a setting switch (not shown) to set the IN point. Then, the user searches the point to be set as the OUT point by rotating the search dial 170, and the image of the point is the OUT point stamp picture. While being displayed on the display unit 194, the OUT point display unit 190 is operated by the rotary encoder 171 for cursor operation.
There is a method of setting the OUT point by moving the cursor upward and pressing a setting switch (not shown).

As a third method, the user operates the rotary encoder 171 for cursor operation to display the IN point display section 18.

Then, the cursor is moved to the OUT point display section 190 by the rotary encoder 171 for cursor operation. There is a method in which the user moves and presses a dialog display switch (not shown) to input a time code to the displayed dialog and set an OUT point.

As a fourth method, after setting the IN point or the OUT point by using any of the above-described methods, the user moves the cursor on the duration display section 191 by the rotary encoder 171 for cursor operation, and There is a method of automatically setting an OUT point or an IN point by inputting a time code into a displayed dialog by pressing a dialog display switch not to be displayed.

When the edit point is set by such a method, the time code is displayed on the IN point display section 189 when the IN point is set, and the time code is displayed on the OUT point display section 190 when the OUT point is set. You. Also, I
At the time of setting each of the N point and the OUT point, the respective time codes are displayed on the current time display section 183. Further, when the setting of both the IN point and the OUT point is completed, the duration is displayed on the duration display section 191.

In the A / V server 1, after setting the editing point of the material data of the reproduction port 20 in this way,
The user presses the recording designation switch 154 to set the current port to the reproduction port 30, and sets the edit point of the created data in the same manner.

In the A / V server 1, when three points are set out of the IN point and the OUT point of the player port and the recorder port, the edit start switch 162 and the preview start switch 163 blink, and the editing and The preview can be executed. Then, in the A / V server 1, when an editing point is set, the control unit 195 of the control panel 80 creates page data, for example, editing information as shown in FIG. In the A / V server 1, the control unit 195 of the control panel 80 creates internal status information as shown in FIG. This internal status information is rewritten according to the situation, for example, when the current port is changed.

Subsequently, in the A / V server 1, in step S5, a preview of the editing section is performed. A /
In the V server 1, when the user presses the preview start switch 163, the preview is started. In the A / V server 1, the preview start switch 163 is turned on during the preview.

When the user presses the preview start switch 163, the control panel 1

At 96, the data is converted into a VFL, and the VFL is sent to the main body together with various commands described later.

The A / V server 1 receives these VFLs and commands by the I / F 92 of the timing manager 90, and transmits the VFLs to the file management unit 101 of the file manager 100 to temporarily store the VFLs and commands. And writes the data to the HDD array 110 via the CPU, and transmits a command to the CPU 53 of the editing manager 50. This command
Specifically, the command includes a command for cueing up to the pre-roll point, a reproduction command for reproducing data, and a stop command for stopping reproduction of data at the post-roll point. The A / V server 1
Based on the VFL and these commands, the video / audio data from the pre-roll point to the IN point is output from the output terminal 54 to a monitor (not shown) using the reproduction data on the recorder side, and the video / audio data from the IN point to the OUT point is output. The data is output from the output terminal 54 to the monitor using the reproduction data on the player side, and the video / audio data from the OUT point to the post-roll point is output from the output terminal 54 using the reproduction data on the recorder side.
Output to monitor.

In the A / V server 1, when the preview is interrupted, the preview can be interrupted by pressing the stop instruction switch 159 of the control panel 80.

After previewing the editing section in this way, the A / V server 1 corrects the editing point in step S6 as necessary. First, in the A / V server 1, the user specifies the reproduction designation switch 153.
Alternatively, by pressing the recording designation switch 154, a device whose editing point is to be corrected is selected. At this time, the pressed switch of the reproduction designation switch 153 or the recording designation switch 154 is turned on. Then, in the A / V server 1, the user sets the I / O according to the edited editing point.
N point designation switch 160 or OUT point designation switch 16
By operating a trim (not shown) of the control panel 80 while pressing 1, the minute correction of the edit point is performed. In the A / V server 1, when this trim is operated, the time code displayed on the current time display section 183 and the IN point display section 189 or the OUT point display section 190 changes one frame at a time. Thus, in the A / V server 1, the time code at the edit point can be increased or decreased and corrected. In the A / V server 1, the IN point designation switch 160 or the OUT point designation switch
By operating the rotary encoder 171 for cursor operation while holding down the point designation switch 161, the time code at the edit point can be increased or decreased to correct it. To delete an edit point, a delete switch (DELETE) (not shown) provided in the control panel 80 is used.
TE) while holding down the IN point designation switch 160 or O
By pressing the UT point designation switch 161, the corresponding edit point can be deleted.

Subsequently, in the A / V server 1, in steps S7 and S8, editing is executed and the editing result is confirmed. In the A / V server 1, when the user presses the edit start switch 162, editing is executed. In the A / V server 1, the editing start switch 162 lights up during editing. In the A / V server 1, when the editing is executed, the results of the steps so far are created as page data as shown in FIG. 13 by the control unit 195 of the control panel 80, and the page data is stored in the memory 197. Hold. Then, the control panel 80 uses the I / F 196 to convert the page data held in the memory 197 by the control unit 195 into a VF.
After that, the VFL is transmitted to the main body together with various commands described later.

The A / V server 1 receives these VFLs and commands by the I / F 92 of the timing manager 90, and transmits the VFLs to the file manager 101 of the file manager 100 to temporarily store them, or the file manager 101 And writes the data to the HDD array 110 via the CPU, and transmits a command to the CPU 53 of the editing manager 50. This command
Specifically, the command includes a command for cueing up to the pre-roll point, a reproduction command for reproducing data, and a stop command for stopping reproduction of data at the post-roll point. The A / V server 1
Based on the VFL and these commands, video / audio data from the pre-roll point to the post-roll point is output to the monitor (not shown) from the output terminal 54 using the reproduction data on the recorder side, and the video / audio data from the IN point to the OUT point is output. The audio data is output to the monitor from the output terminal 54 using the reproduction data on the player side, and the video / audio data from the OUT point to the post-roll point is output from the output terminal 54 to the monitor using the reproduction data on the recorder side.

After executing the editing and confirming the result of the editing in this way, the control panel 80 displays the information on the next page on the display unit 180.

In the A / V server 1, step S4
Steps S8 to S8 are performed for each page, and all page data constituting one program is created. The page data finally obtained in this way is, for example, as shown in FIG. That is, the page data is composed of the information of the device name, the file name, and the editing point in the recorder and the player for each page, and the data for each page is accumulated for all pages.
Then, on the page next to the last page, an end code is added to the file name part of the recorder. A page number, which is identification information for identifying a page, is represented by continuous information assigned to each page in accordance with the creation order of page data such as a serial number. In the page data shown in the figure, the file name on the player side is the same for all pages,
Of course, different files may be used as the material data. On the other hand, it goes without saying that the file name on the recorder side must be the same for all pages.

In the A / V server 1, after creating all the page data, the page data is corrected in step S9 as needed. That is, the A / V server 1 can correct the page data at any time even after the program is created. Here, in the case of a mode other than the edit mode, the user shifts to the edit mode by pressing the mode switch 164 first. In the A / V server 1, the user presses the back space switch 167 or the forward space switch 168 to display a desired page on which the page data is to be corrected on the display unit 180. Then, in the A / V server 1, the editing point is corrected in the same manner as the method previously described in step S6, and if necessary, a preview is performed in the same manner as in step S5. By pressing 162, the editing is executed. The execution of this editing is performed first in step S7.
And the same processing as in step S8.

By doing so, the A / V server 1 creates page data in which the correction is reflected.

Further, the A / V server 1 can perform editing in page units as shown in step S10. That is, in the A / V server 1, a new page can be inserted between pages that have already been created, or a page that has already been created can be moved.

Here, consider a case where page data composed of four pages as shown in FIG. 16 is created. This page data is created by adding the fourth page after creating the third page, and the information of the edit point in the fourth page recorder is between the first page and the second page. It is in. In this case, the page
The relationship with a completed package, which is a so-called complete package, is as shown in FIG. As described above, when the creation order of the page data is not created in the order on the time axis, the created page data is not arranged in chronological order, and it is difficult to capture the image of the complete packet. . Therefore, in such a case, for example, it is difficult to search for an arbitrary page in the complete package.

Therefore, the A / V server 1 has an automatic renumbering function for automatically correcting and rearranging the page numbers in chronological order of the information of the editing points in the recorder at the time of editing, regardless of the order of generating the page data. Have.

In the A / V server 1 described above, when performing editing in page units, the user presses the above-described insert mode switch 165 to change the page according to the editing point of the new page. Specify whether to insert or overwrite the existing page. At this time, “INS” or “OVL” indicating whether the mode is a mode for inserting a page or a mode for overwriting is displayed on the insertion mode display section 192 of the display section 180 of the control panel 80.

Here, the case where the page data shown in FIG. 16 is created in the “INS” mode will be described.
In this case, when the user presses the edit start switch 162,
The A / V server 1 first executes steps S7 and S8
The same editing process as that described above is performed, and the page numbers are renumbered in the order of the edit points in the page data recorder, as shown in FIG. This situation is represented by the relationship between the page and the complete packet, as shown in FIG. That is, the A / V server 1 operates the auto-renumbering function with the execution of the editing, and sets the second and third pages in FIG. 16 to the third and fourth pages, respectively, and sets the fourth page in FIG. Insert as page number.
