It has advantages that magnetic tape devices do not have in that it can perform ultra-high-speed search and detailed editing in frame units.

When editing with this kind of non-linear disk device, especially when performing editing (non-linear editing) taking advantage of the non-linear characteristics, a graphical user interface is displayed on the screen of the editing apparatus, and this user interface is displayed. While interacting, using a pointing device such as a mouse to select, cut out, and paste a scene (also referred to as a cut; represented by a scene in this specification), FIT / FILL (when the length of the edit section is different) Editing operation such as adjusting the playback speed of a material to adjust its length. FIT is shortened and FILL is lengthened.)

[0004] According to this, information such as IN / OUT points for each scene (hereinafter referred to as "edit information") on an editing device.
Can be generated, and the non-linear disk device can reproduce an editing destination material (hereinafter, referred to as a “destination material”) from an editing source material (hereinafter, referred to as a “source material”) based on the editing information.

Conventionally, the above-mentioned editing information is called an EDL (Edit Decision List or Edit Data List) file in which information such as IN / OUT points is arranged for each scene and collected into one text file. Things were used. That is, for each scene, the specific information of the source material (such as a file name) in which the scene is recorded, the specific information of the destination material (such as a file name), and the information of the IN / OUT points of the source material and the destination material (Time code, etc.) and other editing information (video / audio channel, editing mode, and other information necessary for editing) are described in text characters and combined into one file.

[0006]

However, the above-mentioned conventional editing information is a text file in which information of each scene is put together and can be handled only in file units. When re-editing the already-edited information (text file), the information in the file is decomposed, the necessary scene information is extracted, inserted, or moved, etc., and then the original file information is restored. In this case, it is necessary to reassemble (reconstruct), and there is a problem that the processing load on the editing apparatus is correspondingly large.

Therefore, an object of the present invention is to make it possible to handle information for each editing unit (for example, scene) independently and individually, thereby facilitating reconstruction of the editing information and improving the editing apparatus. The object is to reduce the processing load.

The length of the destination material is increased by the section length between the IN point and the OUT point of the new page. -Overlay mode A new page is inserted according to the IN / OUT points input to the recorder of the new page. In this mode, the length of the destination material does not change. Splitting a page Divide one page into two pages. For example, if the original page is A and the divided pages are a1 and a2,
The IN point of page A is the IN point of page a1, and the OUT point of page A is the OUT point of page a2. And
The OUT point of page a1 and the IN point of page a2 are division points. Delete page (CUT) Delete an arbitrary page. Deleted pages are stored in a buffer inside the unit (but only for one page). Using the data in this buffer, a new page can be inserted (in the insert mode) or pasted (in the overlay mode) at an arbitrary position. Move Page Move the position of any page. The target page is deleted and stored in the buffer, and a new page is inserted (in the insert mode) or pasted (in the overlay mode) at a desired position using the data in the buffer. (6) End of Editing (Step S7) Press the lit PLAYER button or RECORDER button to end the editing.

<Pages and Programs> Next, "pages" and "programs" which are the points of the present invention will be described. In general, the final purpose of editing is to select and combine necessary scenes from source materials shot and recorded in a studio, a video location, or the like, to create a destination material having intended contents. FIG. 5 is a conceptual diagram of editing one scene. In the figure, a desired scene portion is between an editing start point (hereinafter referred to as “SRC.IN”) and an editing end point (hereinafter referred to as “SRC.OUT”) of a source material. The video / audio information of this section (or one of video information and audio information; hereinafter, referred to as “video / audio information”) is designated as a destination material specified section, that is, a destination material editing start point (hereinafter, “DST.IN”). ") And the end point of editing (hereinafter" DS
T. OUT ").
Editing of one scene is performed. As a result, "SR
C. IN "," SRC.OUT "," DST.IN ",
Editing information including “DST.OUT”, “source material name”, “destination material name”, and other information necessary for editing (information such as an editing channel and an editing mode) is generated. Play and output the destination material based on the information. Specifically, a non-linear disk device is
The SRC. Of the source material specified by the source material name. IN and SRC. OUT is output to the destination material DST. IN and DST. It is inserted between OUT and reproduced, and the destination material after the reproduction is output.

In the present invention, the editing information is managed by the concept of "page" in scene units. In FIG. 5, an edit data page (hereinafter, simply referred to as “page”) is schematically shown. The page 60 corresponds to the unit editing information described in the gist of the invention, and one page 60 is
"SRC.IN" of one scene in the above example,
“SRC.OUT”, “DST.IN”, “DST.O”
"UT", "source material name", "destination material name" and other information necessary for editing, as well as page identification information and link information to other pages (corresponding to the related information described in the summary of the invention) including.

FIG. 6 shows an example of the structure of the page 60. The page number (PAGE.NO), the source material name (SRC.NAME), and the source material editing start point (SRC.IN) which are the identification information of the page are shown. Including. Further, it includes an editing end point of the source material (SRC.OUT), an editing start point of the destination material (DST.IN), and an editing end point of the destination material (DST.OUT).
Further, other information necessary for editing, for example, editing mode information (MODE) such as insert and overlay, and editing channel information (CHANNN) such as video and audio channels.
EL) and link information to other pages, for example, the forward page number (FROM.
NO) and information such as the rear page number (TO.NO). In addition, other information such as a destination material name may be included.

FIG. 7 shows an example of the structure of a program 61 composed of a plurality of pages 60. In FIG. 7, one program 61 is composed of n-1 pages 60 from page numbers 0 to n.
Is configured. The program 61 here
Means completely different from the above-described control program (the control program executed by the CPU 31 of the main unit 30 and the control unit 55 of the non-linear disk device 50). That is, the control program describes the control processing procedure in a predetermined development language, but the program 61 is a set of pages 60 describing editing information, and is not a command for instructing a CPU or the like to perform a control operation. No difference. In this specification, "program"
In this case, it means such “a collection of pages 60 describing editing information”. In FIG. 7, the page 60 of page number 0 and page number n is a special page including only the page number and link information. These two pages are non-editable pages and are used as start pages when following the links of the pages. For example, when tracing a page by forward reproduction, the page of page number 0 becomes a start page, and when tracing a page by reverse reproduction, the page of page number n becomes a start page. In this specification, the page with page number 0 is particularly called a “top anchor page”, and the page with page number n is called a “last anchor page”.

FIG. 8 is a conceptual diagram showing page links. Now, as shown, page numbers 2 to 7
Assuming that there is a program including pages 60_2 to 60_7, these pages are indicated in link information (FROM.NO, TO.NO; these correspond to related information described in the gist of the invention) of each page. Combined in order. That is, taking a forward reproduction link as an example, the page 60_2 is stored in the FROM. In accordance with the value of page number 1 (not shown) in accordance with the value of “1” (“1”), the TO. Link to page 60_3 of page number 3 according to the value of NO ("3"). Similarly, page 60_3 links to page 60_5, and page 60_
5 links to page 60_4, page 60_4 links to page 60_6, and page 60_6 links to page 60_
Link to 7. As a result, as shown by the arrow line in the figure, a series of page links is performed. Since this link is the order of the scenes in the destination material itself, it corresponds to the editing intention based on the information of one program. The reproduction and output of the destination material can be performed without any trouble.

Here, as described above, when one unit of editing information is handled as a “page” and a group of pages is handled as a “program”, the merit of editing information as compared with the conventional EDL is smaller. The point is that the editing procedure can be simplified.

FIGS. 9 to 11 are conceptual editing diagrams showing one example. First, a case where an arbitrary scene is deleted (CUT) will be described. In FIG. 9, pages 60_1 to 60_4
Of the destination material 62, the section B and the page 60_2, the section B and the page 60_2, the section C and the page 60_3, and the section D of the destination material 62.
And page 60_4 correspond to each other.
Now, for example, when deleting the section C of the destination material 62, the page 60_3 corresponding to the section C is deleted from the program, and all the sections on the rear side in the editing order time axis direction (in the illustrated example, the section 60_3). D) corresponding to each page (in the example shown, page 60_4).
IN and DST. OUT, that is, in the illustrated example, the DST. IN and DST. IN and the DST. OUT is recalculated, and
Link information of page 60_2 and page 60_4 (FRO
M. NO, TO. NO) (page 60_1 → page 60_2 → page 60_4). In addition,
It is desirable to temporarily store the data of the deleted page 60_3 in a storage area such as a buffer. This is because a so-called CUT & PASTE (cut and paste) operation can be performed by using the stored data when inserting (or pasting) a page described later.

FIG. 10 shows an example in which the data of the page 60_3 stored in the buffer or the like is inserted into an arbitrary position (between the section A and the section B in the figure) of the destination material 62 in the insert mode. In this case, sections after the insertion position (section C, section B, and section D in the example shown).
Of each page 60_3, 60_2, 60_4 corresponding to
ST. IN and DST. OUT is corrected, and the link information (FRO) of the page 60_1 corresponding to the section immediately before the insertion position (section A in the illustrated example) and the pages 60_3, 60_2, and 60_4 corresponding to the section subsequent to the insertion position.
M. NO, TO. No) only needs to be updated.

FIG. 11 is a conceptual diagram of FIT / FILL. As mentioned earlier, FIT is source material 6
3 is an editing operation for reducing the length of the target material 64 and inserting it into the target section 63a of the destination material 64.
Is an editing operation for extending the length of the source material 64 and inserting it into the target section 64a of the destination material 65. According to the concept of the page of the present invention, the DST. By adjusting OUT, such FIT /
The operation of FILL can also be performed flexibly.

Therefore, as described above, according to the present invention, a scene can be deleted, moved, inserted or pasted, or an editing operation such as FIT / FILL can be performed in page units. This eliminates the need for decomposition processing (which is decomposed into page units from the beginning), and has the beneficial effect of reducing the processing load on the editing device.

The main functions of this embodiment are functionally realized by an organic combination of a hardware asset including a microcomputer and software assets such as an OS and various control programs. Since the hardware resources and the OS can be general-purpose ones, the essential items indispensable for the present invention are that the editing information for each scene is substantially applied by applying the concept of “page” and “program”. It can be said that it is concentrated in the function part to manage. Therefore, the present invention
All of the functional parts for managing the editing information for each scene by applying the concept of the “page” and the “program” or all the main parts thereof are digitized and stored, a floppy disk, an optical disk, a compact disk, a magnetic tape, a hard disk or Includes recording media such as semiconductor memories or components containing these recording media (unit products, finished products, or semi-finished products). In addition, the recording medium or the component includes not only a recording medium or a component on a distribution channel itself but also a recording medium or a component on a network that provides only recorded contents.

According to the present invention, unit edit information generating means for generating unit edit information for each edit unit, and relation information generating means for generating relation information indicating a connection relationship between the unit edit information are provided. Since the unit editing information and the related information are managed as a set of information, individual and direct operations can be performed on each unit editing information, and the connection of each unit editing information can be performed. Since the unit editing information is specified by the related information, it is possible to correct necessary information associated with the above operation for other unit editing information other than the operation target. Therefore, information for each editing unit can be handled independently and individually, whereby reconstruction of the editing information can be facilitated and the processing load on the editing device can be reduced.
