DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editing apparatus for performing editing by using a plurality of video tape recorders in a broadcasting station, for example.

[0002]

2. Description of the Related Art In conventional video tape editing, for example, so-called electronic editing of a video tape, necessary video signals and audio signals are sequentially recorded from an original tape on a recording tape (master tape). Things.

As an editing system for performing this electronic editing, one 1: 1 editing system is used for both the original and master VTRs, or a plurality of original and master VTRs are prepared, and a post-production switcher and a mixer are controlled to control the master. There is an apparatus that processes a recording signal during editing and recording on a tape to enable an advanced montage effect, audio mixing, and the like.

FIG. 4 shows a so-called A, B-roll editing system as an example of an editing system.

In FIG. 4, reproduced VTRs 100, 1
01 (A-roll VTR, B-roll VTR) is connected to the post-production switcher 102, and the signal from the VTR 100 or 101 switched by the post-production switcher 102 is sent to the master VTR 103 for recording. The editing device 10
Reference numeral 4 denotes a control signal based on a preset editing list (editing data), which is transmitted to each of the VTRs 100, 101, and 103.
And sends it to the post-production switcher 102. As a result, the operations of the VTRs 100, 101, 103 and the switcher 102 are controlled based on the edit list and automatic editing is performed.

Here, the feature of the A, B-roll system using two reproduction VTRs shown in FIG. 4 is that a post-production switcher is provided, so that a high degree of perfection can be expected by making full use of video processing. That is.

In the control (edit control) of the electronic editing system as described above, usually,
A so-called list management process based on a program list (edit list) is performed.

[0008] In the list management processing, the clean-up processing means, for example, a signal from the A-roll original VTR followed by a B-roll original VT.
In the case of recording the signal from R, when the in-point of the B-roll is before the out-point of the A-roll, the out-point of the A-roll is changed to the B-roll. The processing is such that the program is automatically changed to match the in-point.

[0009]

The electronic editing system includes the original VT for A-roll.
In addition to the R and B-roll original VTRs, there are also editing systems that simultaneously use the C-roll original VTRs.

The C-roll original VTR operates in synchronization with the master VTR. For example, a signal from the C-roll original VTR is transmitted to the A,
B- Used for editing such as insertion during roll editing.

However, the conventional editing apparatus has a data structure in which list processing is not easily performed on the C-roll. For example, the conventional editing data of the C-roll is only written in a so-called NOTE statement. Therefore, when editing content is changed,
The operator had to perform the work of rewriting data one by one. For this reason, the cleanup processing of the C-roll edit data is extremely difficult.

In view of the above, the present invention has been proposed in view of the above-mentioned situation.
It is possible to detect the overlap of the edit data when cleaning up the edit data of the C-roll, and to automatically correct and edit the time code of the edit data according to the type of the overlapping portion, thereby facilitating the cleanup processing. It is an object of the present invention to provide an editing device capable of performing the following.

[0013]

SUMMARY OF THE INVENTION An editing apparatus according to the present invention has been proposed in order to achieve the above-mentioned object.
Means for taking in data of the in-point and out-point of the edited data and the in-point and out-point of the second edited data; and a switching section for switching between the first edited data and the second edited data. A judging means for judging whether or not there is an overlap; and, based on the judgment result of the judging means, when the front part of the second edit data overlaps the rear part of the first edit data, the first edit Only the data at the out point of the data is corrected based on the data at the in point of the second edit data, and if the rear part of the second edit data overlaps the front part of the first edit data, the first Only the data at the in-point of the edit data is corrected based on the data at the out-point of the second edit data, and if the second edit data overlaps the inside of the first edit data, the second Based on the in and out point data of the edited data A correction means for correcting the in-point and out-point data of the first edit data; and an editing means for editing the master tape based on the in-point and out-point data of the edit data corrected by the correction means. Things.

That is, the editing apparatus of the present invention detects the overlap of the edit data, and according to the type of the overlap portion, not only the A-roll edit data and the B-roll edit data but also the C-roll edit data in the edit control. This makes it possible to automatically perform a list management process (for example, a cleanup process, which is one of the list management processes).

[0015]

According to the editing apparatus of the present invention, A-roll and B-roll
Since the overlap of each piece of edit data corresponding to the C-roll is detected together with the roll, and the time code of the edit data is automatically corrected and edited (that is, the cleanup process is performed) according to the type of the overlap portion, the edit is performed. The contents can be easily changed.

[0016]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the editing apparatus according to the embodiment of the present invention uses an A-roll player (V
TR) 10 and reproduction signals from a B-roll player (VTR) 11 via a switcher 12 to a recorder (VTR).
13 (or recording), and a C-roll player (VT) that starts in synchronization with the recorder 13
R) 19, and further comprising an editing controller 14 for controlling the editing device, wherein the editing controller 14 edits each of the editing data corresponding to the A-roll, B-roll, and C-roll. The relationship between the IN point, the OUT point, and the edit type is compared, and each edit data is corrected based on the comparison result.

That is, in the editing apparatus shown in FIG.
A-roll player 10, B-roll player 11, and C
-Each reproduction signal of the roll player 19 is connected so as to be supplied to the switcher 12. The switcher 12 switches and outputs a reproduction signal of each material of the A-roll, B-roll, and C-roll according to a control signal from an editing controller 14 that controls each component based on editing data. . Also, this switcher 12
For example, a predetermined video conversion process (for example, a so-called dissolve process, a wipe process, or the like) is performed on a video signal or the like sent from each of the players based on the edit data to form a special effect image. Is possible. The output from the switcher 12 is the recorder 1
Sent to 3.

Further, the A-roll players 10, B
The -roll player 12, the C-roll player 19, and the recorder 13 are also controlled by the control signal from the editing controller 14 based on the editing data, such as reproduction start or recording start. Specifically, the operations of each player and the recorder are controlled based on the time code for the player and the time code for the recorder, which are part of the editing data. In this embodiment, a time code is used for each frame.

As described above, the operation of each player, recorder and switcher is controlled by the control signal from the editing controller 14 based on the editing data, thereby enabling automatic editing.

Further, the monitor 18 is, for example, the switcher 12
The monitor 18 allows the operator to watch, for example, a video being edited.

Here, in the configuration of the present embodiment, for example, when the above-described cleanup processing is performed, the following operation is performed.

First, it is assumed that the edit data has already been created, and that the edit data is stored in the edit data storage memory 15 built in the edit controller 14. First, the control panel 17 performs, for example, a dialogue on execution of the cleanup processing to start the execution of the cleanup processing.

In the cleanup processing section 16 for performing the cleanup processing, the A-roll and the B-roll stored in the memory 15 for storing the edited data are based on the input edited data inputted from the control panel 17. , C-roll edit data is processed for each page, for example. That is, as shown in a flowchart described later, the relationship between the in-point and out-point of each edit data corresponding to the A-roll, B-roll, and C-roll and the edit type is compared, and based on the comparison result, Modify the edit data. Thereafter, all the processes of the specified page of the corrected edit data are performed.

FIG. 2 shows the above A-roll, B-roll and C-roll.
9 shows a flowchart of a correction in a cleanup process of editing data of a role.

[0026] In FIG. 2, in point of the edit ED ₁ is edited data in step S1 in the editing list I
Capture data of N ₁ and OUT point OUT ₁ (time code etc.), taking in the edit ED ₂ of the in-point IN ₂ and OUT point OUT ₂ of the data which is input edit data in step S2 (time code etc.).

In step S3, the above-mentioned edit ED ₁
And from the data of ED _2, to determine whether or not the overlap is in the editing data. If it is determined in step S3 that there is no overlap, the flow advances to step S8 to execute an editing process. If it is determined in step S3 that there is an overlap in the edited data, the process proceeds to step S4, and the state of the overlap (overlap type) is determined in step S4.

Here, as the overlap type, as the simplest example, three types of overlap types as shown in FIG. 3 can be considered. That is, as shown in FIG. 3, edited in the rear of the edit ED ₁ ED ₂
Edit ED ₁ with Type P _R with overlapping front
Can be considered of the type P _F to the rear of the edit ED ₂ overlaps the front, and a type P _C that editing ED ₂ overlaps the inside of the edit ED _1. In addition, not only these, but also complicated overlapping states in which these are compounded together exist, but here, these three types will be described in order to simplify the description.

In step S4 of the above flowchart,
The type of the overlap of the edited data is the type P _R , P
_F, it is determined which one of the P _C.

[0030] In this step S4, when it is determined that the type P _R, the process proceeds to step S5. At the step S5, the edit ED ₁ OUT point OUT
Only _1, modified (to modify the time code) based on the in-point IN ₂ edit ED ₂ to.

If it is determined in step S4 that the type is P _F , the process proceeds to step S6. At the step S6, based on the out-point OUT ₂ of the edit ED _2, in point IN ₁ of the edit ED _1, for example, A- roll-in point, B- IN point of the roll, the C- roll-in point Perform a shift backward (time code correction).

[0032] In step S4, when it is determined that the type P _C is set based the OUT point OUT ₁ of the edit ED ₁ In point IN ₂ edit ED _2, further editing ED ₁ In point IN ₁
The set on the basis of the out-point OUT ₂ of the edit ED ₂ (modification of the time code).

Thereafter, in step S8, actual editing (recording in the recorder 13) is executed.

As described above, according to the editing apparatus of the present embodiment, in the editing control, the list including the editing data of not only the A-roll player 10 and the B-roll player 11 but also the C-roll player 19 is included. Since the management process (for example, the cleanup process, which is one of the list management processes) is performed, the operator must rewrite the data one by one even when the edited content is changed. There is no need to perform this, and therefore, the above-mentioned cleanup processing becomes very easy.

[0035]

As described above, in the editing apparatus of the present invention, the overlap of the edit data is detected, and if only the A-roll edit data and the B-roll edit data are used in the edit control according to the type of the overlapped portion, Since the list management process (for example, a cleanup process, which is one of the list management processes) including the C-roll editing data is automatically performed, even if the editing content is changed, the operator is not required. Does not need to rewrite data one by one,
The cleanup process becomes very easy.
