Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing apparatus, and is suitable for an editing apparatus and an editing method for extracting a necessary portion of an editing material and editing the extracted material.

[0002]

2. Description of the Related Art Conventionally, material data obtained by a cameraman capturing a material image with a video camera or the like is recorded on a magnetic tape and edited by an editing device. In this case, the editing operator visually confirms the material video recorded on the magnetic tape while reproducing the magnetic tape using the reproducing device of the editing device, extracts a portion necessary for the editing work, and records the portion on another medium ( By downloading the data, edited data including only necessary video and audio is obtained.

[0003]

By the way, when a photographer uses a video camera to capture a material image, the photographer records the scene on a magnetic tape for a scene that is determined to be necessary for later editing work. Make a note of the time code when it is done.

An editing operator loads a magnetic tape on which material data is recorded in a reproducing apparatus in an editing operation, locates a scene determined to be necessary by the cameraman based on the time code noted by the cameraman, and searches for a scene. After confirming the contents of the scene, this is recorded as a necessary material on another medium.

However, in the method in which the photographer informs the editing operator of the recording position of the scene determined to be necessary by writing the memo, the editing operator operates the reproducing apparatus for each scene indicated by the time code to search for the cue. There is a problem that complicated work such as performing is required.

The present invention has been made in view of the above points, and an object of the present invention is to propose an editing apparatus and an editing method in which editing work is easier and more accurate.

[0007]

According to the present invention, in order to solve the above-mentioned problem, identification data is detected by performing high-speed access to a tape-shaped recording medium, registered in a predetermined file, and stored in a predetermined file. Since the editing list of the material data is created using the registered identification data, it is not necessary to access the material data of the tape-shaped recording medium in the editing work for creating the editing list. Therefore, the operation of creating the edit list is simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

(1) Tape Format FIG. 1 shows a recording pattern of a magnetic tape 1 on which a material video imaged by a video camera is recorded. At the center of the magnetic tape 1, a digital video signal and an audio signal are recorded by a rotary head. Is recorded on the inclined track TD. Note that the inclined track TD includes an area TDV in which a digital video signal is recorded and an area TDA in which a digital audio signal is recorded. On one edge of the magnetic tape 1, an audio track (longitudinal track) TA on which an analog audio signal is recorded by a fixed head.
Is generated. At the other edge of the magnetic tape 1, a control track (longitudinal track) TC on which a control signal is recorded by a fixed head is generated, and a time code signal is recorded by a fixed head at a position adjacent to the control track. The generated time code track (longitudinal track) TT is generated.

The time code signal (LTC) recorded on the time code track TT is, as shown in FIG.
One frame area consisting of 80 bits is configured as one unit. This one frame area includes a synchronization signal area for recording a synchronization signal and a time code (HH: M).
Eight time code recording bit areas for recording M: SS: FF, user's bits (D1D2: C1)
C2: B1B2: A1A2) and eight user bits recording areas.

More specifically, the "Hour" information of the time code is recorded in two bit areas (H, H) represented by bits 48 to 51 and 56 to 59, and the "Hour" information of the time code is set to "Mi".
The "nute" information is recorded in two bit areas (M, M) represented by bits 32 to 35 and 40 to 42, and the "Second" information of the time code is bits 16 to 19 and 24 to 26.
Are recorded in two bit areas (S, S) represented by
The “Frame” information of the time code includes bits 0 to 3, 8,
9 are recorded in two bit areas (F, F).

A start code, a mark identification code, a data serial number code, and a checksum code are recorded in the eight user's bit recording areas. The start code is bits 60-6
3, two bit areas (D1, D2,
D2), the mark identification code is stored in bits 44 to
47, 36 to 39 (C1, C2
The data serial number recorded in 2) is bits 28 to 31,
Two bit areas (B1, B2,
2), the checksum code is stored in bits 12 to
15, two bit areas (A1, A
Recorded in 2).

The start code is composed of 1 bit consisting of 80 bits.
In the frame, it is a code indicating that the area where the time code information is recorded and the user's area start, and "OFFh" data is always recorded.

The mark identification code is a code for representing the type of mark data. By the photographer (Re
When "c start mark" is marked, "20h" is recorded as mark identification data, and when "shot mark 1" is marked by a cameraman, "21h" is recorded as mark identification data,
When "shot mark 2" is marked by the cameraman, "22h" is recorded as mark identification data. When "edit mark 1" is marked by an editing operator who operates the editing apparatus, "23h" is recorded as mark identification data,
When the edit operator marks “Edit mark 2”, “24” is used as mark identification data.
h "is recorded.

The mark identification code is recorded not only for one frame at the moment when the marking is designated by the cameraman or the editing operator, but is recorded continuously for 20 frames from the moment when the marking is designated. . For example, if the time code is "01:12:20:
It is assumed that the shot mark 1 is marked by the cameraman at the timing represented by “05”. In this case, the time code "0"
1: 12: 20: 05 "to the time code" 01: 1
During the 20 frames up to 2:20:24, the data of "21h" continues to be recorded on the time code track as a mark identification code.

The reason why the same mark identification code is recorded continuously for as long as 20 frames is to ensure that the editing apparatus described later can read this mark identification code. A read error may occur when attempting to reproduce information from this timing track due to a tape data defect or bit error. In such a case, if the mark identification code is written only in the time code "01: 12: 20: 05", the mark information may not be obtained from the tape. There is. When the tape is run at high speed, C
In some cases, data of all frames cannot be searched due to the processing capability of hardware such as a PU. Even in such a case, the time code “01:12:20:
If the mark identification code is written only in the “05” part, mark information cannot be obtained from the tape, and as a result, it is possible that the same important scene cannot be searched. is there.

However, according to the format shown in FIG. 2, during 20 frames from the marked timing,
Since the same mark identification code is recorded, even if the mark identification code recorded in the first frame cannot be read, by reproducing the mark identification code recorded in the subsequent frame,
The mark identification code can be reliably searched. Even when the tape is run at such a high speed that the data of all the frames on the time code track cannot be accessed, it is sufficient if at least one of the 20 frames can read the mark identification code. The identification code can be retrieved from the tape.

The data serial number code is data indicating the number of the frame from the beginning in 20 consecutive frames. For example, in the above-described example, the data serial number of the frame having the time code “01: 12: 20: 05” is “01” indicating the first frame.
Is recorded and the time code "01: 12: 20: 24"
"20" indicating that the frame is the twentieth frame is recorded as the data serial number of the frame.

The reason why the data serial number code is stored is to obtain the time code of the first frame, that is, the time code at the time of marking. For example, it is assumed that the data of the eighth frame can be read out of the data of 20 frames recorded on the time code track by the high-speed tape running by the high-speed reproduction. The time code of the eighth frame read is 01: 12: 20: 12,
The data serial number code is “08”. From these two data, the first time code is easily expressed as “01: 1
2:20:05 ".

Display marker information corresponding to each marker.

Each marker information display section 223A, 223B,
As shown in FIG. 8, tape identification display portions 224A, 224B, 224C,... 223C indicate the type of the magnetic tape 1 on which the respective markers are recorded.
And stamp images 221A and 221 corresponding to each marker
B, 221C,...
A, 222B, 222C,..., And a marker type display section 225A, 225B, 225 for displaying the type of each marker
C,..., Time code display sections 226A, 226B, and 2 displaying the time code at the position where the marker is added.
26C,... Are provided.

For example, in FIG.
3A is the one in which the marker represented by the marker information display section 223A is recorded in the tape number “Reel 0001”, and the stamp image 2 at the position where the marker is added.
Reference numeral 21A denotes an image displayed on the stamp image display section 222A, and the type of the marker is a recording start mark RSM, and the time code "2:30:30" is displayed as marker information.

On the other hand, the editing operator operates the keyboard 122 or the mouse 121 to operate the Files panel PN.
When the display by the marker list table 230 is selected by clicking the selection button 229 of L2, the system controller 114 selects each marker information display field 231A of the marker list table 230 shown in FIG.
231B, 231C,... Displays marker information corresponding to each marker.

The marker list table 230 includes the marker information display columns 231A and 231 of the marker list table 230.
B, 231C,..., A tape identification display section 232 for identifying and displaying the magnetic tape 1 on which the markers displayed are recorded.
, A marker number display unit 233 indicating the order of addition of each marker by a number, a marker type display unit 234 displaying the type of each marker, and a time code display displaying a time code at the position where each marker is added Unit 235, a stamp image flag display unit 236 for displaying whether or not a stamp image corresponding to each marker has been captured, and an editing operator operating the keyboard 122 or the like to input desired information for each marker. A memo display unit 237 for displaying memo information is provided.

For example, in FIG.
1A, the marker represented by the marker information display field 231A is recorded in the tape number “Reel 0001”, the type of the marker is a recording start mark RSM, and the marker at the position where the marker is added. The time code is “2 minutes 30 seconds 05”, indicating that the stamp image corresponding to the marker has been captured and the memo information corresponding to the marker has not been input.

Incidentally, when the marker is scanned while the magnetic tape 1 is being reproduced at high speed or fast-forwarding / rewinding, if the scanning speed is 20 times or more, it is difficult to capture the stamp image. The stamp image flag display section 236 displays “absence” indicating that no stamp image has been captured, whereas the stamp image approximate to the marker position is captured when the scan speed is 20 × or less. As a result, the stamp image flag display section 236 displays “approximation” indicating that a stamp image at an incorrect approximate position with respect to the marker position is captured.

In particular, when the recorded magnetic tape 1 is loaded into the tape recording / reproducing unit 50 and the editing operator clicks the marker scan button 207A or 207B on the GUI screen to designate a marker scan operation, the hybrid recorder The 100A tape recording / reproducing unit 50 scans the magnetic tape 1 at a high speed of 20 times or less in the direction designated by the clicked marker scan button, and searches for a marker.

In this case, when the editing operator clicks the marker scan button 207A or 207B, the GUI 120 displays a dialog box shown in FIG. 9 on the GUI screen, and either or both of the marker scan and the periodic sample are displayed. Wait for it to be specified. At this time, when the editing operator clicks, for example, both the marker scan button 216 and the periodic sample button 217, the system controller 114 responds to this, and as shown in FIG. While searching at the following high speed,
Capturing sample images CP _S in the memory 125 together with a time code for each time period T. When the sample image CP _S with such stamp corresponding to each marker image CP _M and Constant Sample is taken in the memory 125, GU
In the marker list 230 on the I screen, “approximate” is displayed on the stamp image flag display unit 236 as shown in FIG. 11 and the marker type display unit 234 corresponding to the sample image captured by the regular sample is displayed. Indicates "SAM".

Thus, as shown in FIGS. 7 and 11, for the marker for which "None" or "approximate" is displayed in the stamp image flag display section 236 of the marker list 230, the editing operator sends the marker search on the GUI screen. By clicking the / return button 206A or 206B, a stamp image of a required marker can be cue-up at an accurate position and captured.

In this case, when the editing operator clicks the marker search forward / return button 206A or 206B on the GUI screen, the system controller 11
4 displays a dialog box 210 shown in FIG. 12 on the GUI screen on the monitor display screen, and the editing operator
A marker to be searched is selected from 11, 212, and 213. The number of selectable markers may be one or plural. Incidentally, the state shown in FIG. 12 shows a state in which the recording start mark RSM and the first shot mark GSM1 are selected as search targets by the editing operator clicking the search target specification buttons 211 and 213 in the dialog box 210.

In this way, the editing operator specifies the marker to be searched in the dialog box 210 on the GUI screen, and then
When the “0” execution button 214 is clicked, the system controller 114 causes the marker search forward / return button 206A or 206 currently clicked by the editing operator from the current position P1 as shown in FIG.
The recording start mark RSM and the shot mark GSM1 are searched in the direction corresponding to B.

Accordingly, the system controller 114 starts searching for a marker from the current position P1 in FIG. 13 in a direction corresponding to the marker search sending button 206A clicked by the editing operator, and searches for a shot mark GSM2 not selected at this time. After passing through, the shot mark GSM1 selected at this time is queued up. At this time, the system controller 114
In the video window 203 of the panel PNL1, a stamp image of the cue-up shot mark GSM1 and a display character "GSM
1 "is displayed.

The system controller 114 repeats the cue-up for the mark selected in this manner, so that the image at the cue-up mark position is stored as a stamp image in the stamp image storage area 118 of the memory 125 of the editing controller 100B. It is updated and registered as a stamp image of a marker to which a stamp image has not been captured or an approximate stamp image has been captured. Incidentally, the time code is accurately captured when capturing the marker. Accordingly, the stamp image and the time code are brought into a state in which the update registration of the accurate stamp image matches.

Thus, in the stamp image flag display section 236 of the marker list 230, "none" indicating that no stamp image has been captured and "approximate" indicating that an approximate stamp image has been captured are shown in FIGS. The stamp image corresponding to the time code of the marker is registered by accurately cueing up each marker position and taking in the stamp image by the above-described accurate search operation for the item No. 13, and the display thereof is sequentially displayed as “Yes”. Switch to.

The stamp image stored in the stamp image storage area 118 in this way differs from the time code DT stored in the time code storage area 117 in the acquisition timing from the hybrid recorder 100A.
Reference numeral 14 denotes that the time code DT is corrected in advance, so that the corrected time code (file time code) DT stored in the time code storage area 117 is the time code of the stamp image stored in the stamp image storage area 118. Will match.

Incidentally, the stamp image taken into the stamp image storage area 118 is a stamp image at a timing delayed from the timing at which the marker RSM is detected by the time required for the process of taking the stamp image, and the GUI 120
Displays an "approximate" character as the stamp image flag 236 on the GUI screen (FIG. 11) to inform the editing operator that the stamp image is a stamp image at a slightly different timing with respect to the marker. It has been done.

Therefore, by confirming the display, for example, by performing the marker search operation described above with reference to FIG. 13 or accessing a specific marker, an accurate stamp image can be captured.

Thus, in the memory 125 of the editing controller 100B, marker information (marker type, time code and stamp image) recorded on the magnetic tape 1 is set.

Here, while the editing controller 100B is downloading material data (video signal and audio signal) from the magnetic tape 1 to the hard disk, the editing operator may set a marker in the marker Log file (memory 125) by himself. Has been made. In this case, the editing operator operates the control unit 1 of the editing controller 100B.
By operating the fifteen mark-in buttons 115A, the system controller 114 of the editing controller 100B stores the marker type in the marker type storage area 116 of the memory 125. In the case of this embodiment, the marker set by operating the mark-in button 115A of the control unit 115 is preset so as to be the shot mark GSM1. By the way, the control unit 11
By operating the 5 mark-out button 115B, the shot mark GSM2 is set.

In this manner, the marker type storage area 116
Is set in the edit controller 10
The system controller 114 of 0B sends a request signal CONT321 of the file time code to the hybrid recorder 100A.

The system controller 60 of the hybrid recorder 100A returns the time code DT held in the time code data holding unit 33 to the editing controller 100B in response to the request signal CONT321 by putting it on the response signal CONT322. Editing controller 100B
Of the time code DT returned from the hybrid recorder 100A,
Thereafter, a preset correction value “+ α” is added in accordance with the timing of capturing the stamp image captured from the hybrid recorder 100A, and this is stored in the time code storage area 117 of the memory 125 as a file time code.

Subsequently, the system controller 60 of the hybrid recorder 100A sends the video reproduced at this time from the tape recording / reproducing unit 50 to the editing controller 100B as a stamp image.
It is stored in the stamp image storage area 118 of the memory 125.
The stamp image stored in the stamp image storage area 118 in this way differs from the time code DT stored in the time code storage area 117 in the acquisition timing from the hybrid recorder 100A.
Reference numeral 14 denotes that the time code DT is corrected in advance, so that the corrected time code (file time code) DT stored in the time code storage area 117 is the time code of the stamp image stored in the stamp image storage area 118. Will match.

[0139] Thus, the hybrid recorder 1
Each time a marker is detected at 00A, the decoder unit 80
Even if the video being processed is not held as a still image in the above, the system controller 114 stores the stamp image approximate to the marker and the time code corrected to exactly match the stamp image in the memory 125, You can register to the Log file.

The marker log file (memory 12
When registration of information (marker type, time code, and stamp image) for each marker in 5) is completed, the GUI 1
20 displays a GUI screen as shown in FIG. 18 on the monitor.

In this case, the GUI 120 displays the stamp image of each marker on the stamp image display screen section 220 of the GUI screen. The GUI 120 displays marker display selection buttons 301, 302, and 303 on the GUI screen. When the editing operator clicks one of these buttons, the GUI 120 displays the stamp image of the marker corresponding to the clicked button. Only the marker information display section) is displayed. For example, when the editing operator clicks a marker display selection button 301 for specifying the recording start mark RSM, the GUI 120 displays only the stamp image (marker information display unit) of the recording start mark RSM on the stamp image display screen unit 220, and When the editing operator clicks on the marker display selection button 302 for designating the shot mark GSM1, the GUI 120
Indicates the shot mark GSM on the stamp image display screen section 220.
When only the stamp image (marker information display unit) is displayed and the editing operator clicks the marker display selection button 303 for specifying the shot mark GSM2, the GUI 120 displays the stamp image display screen unit 220.
Only the stamp image of the shot mark GSM2 (marker information display section) is displayed.

In the state where the stamp image (marker information display unit) is displayed on the stamp image display screen unit 220, the editing controller clicks any one of them, and the system controller 114 causes the clicked stamp image to be displayed. The magnetic tape 1 or the hard disk can be queued up at the position. In this case, the cue-up image is displayed in the video window 203 of the Viewer panel PNL1.

When the editing operator clicks and selects two stamp images from the stamp image display screen section 220, the system controller 114 transmits the material data between the markers corresponding to the selected two stamp images to the time stamp. It can be set as edit material data on the line. For example, in FIG. 18, when the editing operator selects the marker information display sections 223B and 223C and designates a desired position on the timeline, the system controller 114 uses the material data between these two markers as the edited material data in the timeline. Can be set on.

Further, as shown in FIG. 19, when a stamp image of a plurality of types of markers is displayed on the stamp image display screen section 220 on the GUI screen, the system controller 114 connects the stamp image display screen section 220 adjacent to the stamp image display screen section 220. The shot marks GSM1 and GSM2 are displayed as one group, and these groups can be set at desired positions on the timeline as one piece of editing material data by the operation of the editing operator.

Also, as shown in FIG. 20, when stamp images of a plurality of types of markers are displayed on the stamp image display screen 220 on the GUI screen, the system controller 114 sets the shot marks on the stamp image display screen 220. Two recording start marks RSM sandwiching GSM1 or GSM2 are displayed as one group, and these groups can be set at desired positions on the timeline as one piece of editing material data by the operation of the editing operator. Thereby, the shot mark GSM1
Alternatively, between the recording start marks RSM on which GSM2 has been set can be set as editing material data (event).

(5) Operation and effect of the embodiment In the above configuration, the editing operator views the GUI screen displayed on the display screen of the monitor and operates the keyboard 12
By operating the mouse 2 or the mouse 121 and inputting a command to search or scan a marker recorded on the magnetic tape 1 of the tape recording / reproducing unit 50 of the hybrid recorder 100A, the system controller 114 of the editing controller 100B causes the hybrid recorder 100A to In response, the search or scan command is transmitted.

[0147] The system controller 60 of the hybrid recorder 100A searches the magnetic tape 1 loaded in the tape recording / reproducing section 50 at a high speed from the beginning according to the command.

In this high-speed search, the tape recording / reproducing section 50 sequentially searches for markers recorded in advance on the magnetic tape 1, detects them in the marker detecting section 55, and takes them into the RAM 37A. Then, the system controller 60 sends the captured marker to the editing controller 100B at a predetermined timing, and stores the marker in the memory 125. The marker information stored in the memory 125 is registered in the marker Log file.

As described above, when the marker on the magnetic tape 1 is registered in the memory 125 (marker log file), the editing operator stores information (marker type, time code and stamp image) on the marker registered in the marker log file. Using the record list list display section 260 (FIG. 1)
4) and edit list creation on the timeline (FIG. 6) can be performed.

Therefore, by temporarily reading the marker and the information related to the marker from the magnetic tape 1 and registering the information in the marker Log file as described above, when a record list or an edit list on the timeline is created,
An edit list can be easily created without reading the material data on the magnetic tape 1 each time.

When the editing operator creates the edit list on the record rest or the timeline in this way, the system controller 114 responds to the operation of the edit operator to display the edit list on the record rest or the timeline created at this time. The editing material data required for editing on the magnetic tape 1 is recorded on the hard disk.

Thus, edited data is created on the hard disk in accordance with the record list created by the editing operator using the marker Log file and the edit list on the timeline.

According to the above configuration, a marker is searched from the magnetic tape 1 and registered in the marker log file, and information (marker type, time code and stamp image) on the marker registered in the marker log file is searched. Is used to create a record list or an edit list on the timeline, so that the editing operator can edit the magnetic tape 1 in the editing work for creating the edit list.
Editing work can be completed without accessing the above material data. Thus, the editing operation can be performed more easily.
