Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an editing method and apparatus for editing, for example, video and audio files recorded on a disk-shaped recording medium.

[0002]

2. Description of the Related Art In recent years, in order to realize easy and quick editing of video and audio, a large-capacity disk-shaped recording medium (for example, a hard disk or the like, hereinafter simply referred to as a disk) capable of randomly accessing a recording medium has been proposed. To) is used. Video and audio data are recorded on the disc in a file format. When editing, the recorded video and audio data files are read and edited. Note that editing using a disk is called non-linear editing, as opposed to normal linear editing using a magnetic tape.

[0003]

By the way, in the non-linear editing of video and audio using the above-mentioned disc, there are three items (1) to (3) below, for example, a black video in which a normal video does not exist. Non-video signal part consisting of
Processing (that is, non-picture processing),
A process of generating a non-speech signal portion (hereinafter referred to as silence) in which normal speech does not exist (that is, silence processing) is required.

(1) When starting reproduction of a disk, a slight rise time is required for a stable transition from the stop state to the reproduction state. Therefore, the leading portion of the editing program is not reproduced stably for this rising time. In such a case, it is necessary to insert a discarded blank portion irrelevant to the main editing program before the beginning of the editing program.

(2) When editing only audio or video only, it is necessary to record a no-picture / no-voice signal in advance over the entire editing section, and then insert the audio or video signal.

(3) When changing video / audio at an arbitrary position in the editing program to no picture / no sound, a no picture / no sound signal is required.

As described above, conventionally, when the non-picture / silent processing is required as described in the above three items, a non-picture / silent signal is generated from an external signal source and recorded on a disk each time. Is used to perform the imageless / silent processing. Such a situation is complicated, and is not preferable in a situation where quick editing is desired.

Accordingly, the present invention has been made in view of such a situation, and eliminates the need for performing non-picture / silent processing each time editing is performed in a non-linear editing using a disc, thereby enabling simple and quick editing. It is an object of the present invention to provide an editing method and an apparatus for realizing the above.

[0009]

According to the editing method and apparatus of the present invention, a specific file that cannot be easily erased is recorded in a disk-shaped recording medium in advance, and when an editing program is created, the specific file is stored in a specific portion of the editing program. The above-mentioned problem is solved by automatically inserting a specific file.

That is, according to the present invention, a non-picture / silent file is recorded in advance as a specific file on a disk-shaped recording medium, and the non-picture / silent file cannot be easily deleted by an editing operator. In addition, at the time of editing that requires non-picture / silent processing, non-picture / silent processing can be automatically performed.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall configuration of an editing apparatus according to an embodiment for realizing the editing method of the present invention.

In FIG. 1, a video signal, an audio signal and the like are supplied to an input terminal 1 as a recording signal to be recorded on a disc.
Sent to

The file storage unit 2 has, as a main component, a hard disk drive using, for example, a hard disk as a disk-shaped recording medium, and stores the video and audio signals supplied from the input terminal 1 in a file format (for example, (Files F1, F2, F3,...). Recording in the file format in the file storage unit 2 is performed by recording address control by the recording control unit 4, while reproduction in the file format is performed by reproduction address control by the reproduction order control unit 5.

The edit data processing unit 6 creates, updates, and changes an edit list (edit list: EDL), and stores the list in the edit list storage unit 7. The edit data processing unit 6 associates management information of file recording by the recording control unit 4 with the edit list, and performs editing based on the edit list.
Based on the file management information and the edit list, the reproduction order control section 5 determines the file reproduction order.

As a result, the file storage unit 2 outputs an editing program formed by reproducing the files in the reproduction order based on the edit list.
This editing program is sent from the terminal 3 to the subsequent stage as a reproduction signal. For example, when the editing device 10 is used in a broadcasting station, the editing program is sent to a broadcasting device and broadcasted as the latter-stage configuration, or is recorded on another recording medium (for example, a magnetic tape or the like). become. It should be noted that the editing program for which the final editing has been completed in this way may be called complete packet data.

By the way, the editing apparatus 1 according to the present embodiment
0, on the disk of the file storage unit 2,
For example, a non-picture / silent file (no-picture / silent file FB) having a length of about 5 seconds to 30 seconds is recorded in advance. The non-picture / silent file FB cannot be easily consciously handled by the operator of the editing apparatus 10, and
Therefore, the file is basically a file that cannot be deleted, and is read only when the editing apparatus 10 itself determines that it is necessary. In order to realize such erasure and the like, the file name of the non-picture / silence file FB is unique and cannot be used by the editing operator.

When the editing apparatus 10 itself determines that it is necessary, for example, as described in the above three items,
This is when no picture / silence processing is required. That is, the editing apparatus 10 (1) does not generate a picture / silence within a slight rise time (the foremost part of the editing program) from the stop state at the time of starting the disk reproduction to the stable transition to the reproduction state. When creating a blank portion, (2) When editing only audio or video first, and recording a non-picture or silence signal in an undefined editing section where no audio or video is recorded, (3) When the video / audio at an arbitrary position in the editing program is changed to non-image / silent, the non-image / silent file FB is automatically read.

FIG. 2 shows a first embodiment of the present invention in which a blank portion with no picture / sound is automatically created at the top of the editing program as in the above item (1). An example of a read file (FIG. 2A) and an example of an editing program (FIG. 2B) are shown.

When performing editing as shown in FIG. 2, the edit data processing unit 6 creates an edit list as shown in FIG. 3, and stores the edit list in the edit list storage unit 7. I do. Note that the cut numbers in FIG. 3 correspond to scene numbers, and the edit points indicate edit in points and out points in the file.

That is, when an editing program is created in which the points P1 and P2 of the file F1 and the video and audio data of the points P3 and P4 and P5 and P6 of the file F2 are linked according to the editing list as shown in FIG. ,
The editing device 10 determines whether the file F1 and the file F2
Prior to the editing of the file F1, the non-picture / silent data of the points PA to PB of the non-picture / silent file FB are automatically read out as shown in FIG. Points P3 to P4 of file F2
By reading and connecting the video and audio data of P5 and P5 to P6, an editing program as shown in FIG. 2B is generated.

In other words, the editing program shown in FIG. 2B is further before (the foremost part) the head of the editing program composed of the files F1 and F2 to be actually sent to the subsequent stage. , A blank portion composed of non-picture / silent data of the non-picture / silent file FB is arranged.

At this time, the editing operator can edit and operate only the editing program portion consisting of the file F1 and the file F2, and is completely conscious of the blank / silent file FB in the blank portion where editing and operation are impossible. Editing is done without doing anything.

As described above, according to the editing apparatus of the first embodiment, when creating an editing program consisting of the file F1 and the file F2, the blank portion consisting of the non-picture / silence is arranged at the forefront. By doing so, for example, when the reproduction is started from the disk stopped state, it is possible to secure a rising time from the stop state to the stable reproduction state. In other words, in the editing apparatus according to the present embodiment, when the reproduction is started from the disc stop state, the reproduction is started from a state of waiting in the margin, so that the file F1 actually output to the outside is output. A stable playback state is achieved at the beginning of the editing program including the file F2 and the file F2, and therefore, it is possible to supply a favorable editing program to the subsequent stage.

In the first embodiment described above, (1)
No picture at the top of the editing program corresponding to the item
Although the description has been given of the case where the silent blank portion is arranged, as described above, the silence / silence file FA is stored in the file storage unit 2 in advance, as in the second embodiment described below. In addition, it is possible to automatically perform the imageless / silent processing of the items (2) and (3).

FIG. 4 shows a second embodiment in which, when only audio or video is edited first as in the above item (2), undefined editing in which no audio or video is recorded is performed. An example in which no picture or no sound signal is recorded in a section is shown. FIG. 4 shows an example in which only a video is edited first, and a silent signal is recorded in an undefined editing section in which no audio is recorded. FIG. 4A shows an example of a read file, and FIG. (B) shows an example of the editing program.
Further, in the example of FIG. 4, as in the example of FIG. 2, a non-picture / silent file is arranged at the forefront of the editing program.

In order to realize editing of only audio or only video as in the example of FIG.
, An edit list is created for each of the video and audio, and the edit list storage unit 7 stores the edit lists for each of the video and audio. If there are, for example, four channels of audio, the edit list is composed of a total of five images and four channels of audio. The contents of each of the edit lists composed of video and audio, and no-picture / silent files are substantially the same as those in FIG. 3, but in the example of FIG. And files corresponding to silence are marked with an A to distinguish them.

In FIG. 4, for example, when audio is not defined and an editing program is created by connecting only the video data of points P3 _{V to} P4 _V and P5 _{V to} P6 _V of the video file F2 _V , the editing device 10 prior to editing the file F2 _V for the video, no-picture / silence file FB _V as shown in (a) of FIG. 4, the point of FB _a PA
_{V ~PB V,} PA _{A ~PB A} automatically reads the non-image / silence data, connect then reads the video data of the video file F2 _V point P3 _V to P4 are brought _V and P5 _V ~P6 _V.

[0029] At the same time, the editing apparatus 10, the portion of the audio that is not defined in the edit section reads silence data PA _A ~PB _A silence file FB _A automatically, defined within the edit section Insert it into the part for audio that has not been done. The length of the editing program for the video, when longer than the length of the silence file FB _A is such that will lead repeat the silent file FB _A.

[0030] The even edit operator when the second embodiment is only capable of editing and manipulation editing program portion of the file F2 _V for the video, silence was not the margin portion and the defined Cannot be edited and operated, and no picture / silent files FB _V , F
This means that B _A was edited without any awareness.

According to the editing apparatus of the present embodiment in the example of FIG. 4, audio is not defined, and the video file F
In case of creating an editing program from only 2 _V of video data, by automatically repeating linked inserting the silent data of silence file FB _A to the audio portion not defined above, silence file FB of limited size _{From A} , it is possible to create a silent background of any length. In the above-described example, the audio portion is described as the undefined portion, but the same applies even if the undefined portion is a video portion.

Also, in the example of FIG. 4, a case where a silent (or no-picture) file is inserted into an undefined portion corresponding to the item (2) has been described. When the video / audio at an arbitrary position in the editing program is changed to no image / no sound as in
_V, it is possible to make use of the FB _A.

As described above, in the editing apparatus according to the first and second embodiments of the present invention, in the non-linear editing using the disc, the editing apparatus automatically uses the previously recorded non-picture / silent file. By arranging the non-picture / silent section at the top (margin) or undefined portion of the editing program, the editing operator can record the non-picture / silent without consciously recording the non-picture / silent signal. Can be created on an editing program. As a result, a stable reproduction output of the leading portion of the editing program can be obtained, and a blank / silent background creation operation prior to independent editing of video / audio can be omitted.

Next, in the above-described embodiment, an example has been given in which the data of the non-picture / silence file FB is arranged in the foremost portion or the undefined portion outside the editing program when the editing program is created. As a third embodiment of the invention,
