Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing method and apparatus suitable for application to, for example, an integrated editing machine, an editing system, etc., and an editing method and apparatus.

[0002]

2. Description of the Related Art A VTR is generally used as a device for recording digital or analog video and audio signals on a recording medium. However, personal computers, workstations, etc. (hereinafter referred to as computers)
In the image processing using, the technique of recording video and audio signals on a hard disk, an optical disk, or the like has become common. Along with this, an editing apparatus has been proposed which can record a reproduced video and audio signal reproduced by a VTR on a hard disk.

FIG. 11 shows an example of such an editing apparatus. The editing apparatus shown in FIG. 11 converts analog video and audio signals reproduced by a VTR into digital video and audio signals by an AD converter. The digital video and audio signals obtained by the conversion can be recorded on the hard disk in the disk drive together with the time code. The configuration and operation of the conventional editing apparatus will be described below with reference to FIG.

An interface circuit 7 is connected to the reproducing VTR 2 shown in FIG. 11, and a disk drive 8 is connected to the interface circuit 7. The reproducing-side VTR 2 is configured by connecting two recording / reproducing heads 3 and 4 to one and the other fixed contacts 5a and 5b of a switch 5, and connecting a movable contact 5c of the switch 5 to a VTR main body 6. . Then, in the VTR 2, the two recording / reproducing heads 3 and 4 are switched by a switching pulse for head switching.

The interface circuit 7 is not shown,
An AD converter for converting the analog video and audio signals supplied from the reproducing VTR 2 into digital data;
SCSI (Small Computer) for supplying the output of the AD converter to the disk drive 8.
Systems Interface) interface circuit.

Next, the operation will be described.

As shown in FIG. 11, the video tape cassette 1 is set in the reproducing VTR 2. Playback side V
When TR2 is in the reproduction state, analog video and audio signals are reproduced from the video tape cassette 1. The reproduced analog video and audio signals are converted into digital video and audio signals by the AD converter of the interface circuit 7.

The digital video and audio data from the A / D converter is then supplied to the disk drive 8 via the SCSI interface circuit and recorded on the hard disk disk in the disk drive 8.
The SCSI interface circuit controls data transfer processing between the A / D converter and the disk drive 8 and between the disk drive 8 and the output terminal 9.

As described above, when digital video and audio data is recorded on the hard disk, unlike the VTR, there is no need to perform rewinding or fast-forwarding operations on the medium, so the time required to access the necessary data is compared with the VTR. In addition, the hard disk does not deteriorate like magnetic tape even if the same place is accessed many times.

Therefore, for example, a digital multi-effector (DM) is connected to the output terminal 9 of the interface circuit 7.
E) and the audio mixer are connected, the digital video data from the hard disk drive 8 is processed by the DME, and the digital audio data from the hard disk drive 8 is processed by the audio mixer, as described below. An efficient editing environment can be provided to the operator.

That is, since it is possible to access desired data at high speed as many times as possible, in the editing work, for example, the DME or the voice mixer can be repeatedly used until the operator can perform the editing processing that he or she is satisfied with. Editing work using can be redone. Moreover, the operator operates the VTR as if using the VTR,
By rewinding or fast-forwarding the magnetic tape many times, it is not necessary to perform the work of setting the position of the magnetic tape to a desired reproduction start point or a position before and after this point.

Also, for example, a recording side VTR is connected to the output terminal 9 of the interface circuit 7, and the digital video and audio data from the hard disk drive 8 is recorded in the video tape cassette set in the recording side VTR. Thus, for example, even when so-called single material is integrated, desired data to be recorded can be accessed at high speed. Therefore, as in the case of using a VTR,
By manipulating R to rewind and fast forward the magnetic tape many times, it is possible to set the position of the magnetic tape to a desired reproduction start point or a position before and after this point. I'm done.

The applicant has previously displayed the first and second points of the image data of a predetermined unit on the display means, and the first and second points of the predetermined unit displayed on the display means. By designating the image data by the designating means and displaying the time code data of the image data of the first or second point designated by the designating means, the state of the related equipment, and the identification number by the control means, the editing efficiency is improved. Editing device that can improve the usability as well as
For example, it is possible to change the contents of the edit files EDL1 to EDLn by deleting, copying, moving, and exchanging the position of the image data in edit units displayed on the screen using a pointing device or a keyboard. You can perform editing work without performing any troublesome work such as playing and rechecking, checking the memory address etc. with the keyboard etc. and entering it, thereby improving the efficiency of editing work. We propose an editing device that can be done (Japanese Patent Application No. 5-874).
No. 13).

[0014]

By the way, in general,
Since the video and audio signals are edited in the editing system based on the time code, when the device shown in FIG. 11 is used in the editing system, it can be reproduced by the VTR 2 on the reproducing side. It is necessary to make it possible to use the time code of the obtained video and audio data when editing. Therefore, if the time code is also recorded when recording the video and audio data on the disc, the time code can be obtained together with the video and audio signals when the disc drive 8 is in the reproduction state. Timecode can sometimes be used.

However, when the video and audio data and the time code reproduced by the reproducing VTR 2 are recorded on the disk set in the disk drive 8, the time code of the video and audio data recorded in a certain area of the disk is It is very likely that the time code of the video and audio data recorded in the other area of the disc overlaps.

This is the case when material cuts respectively recorded in a plurality of video tape cassettes are sequentially recorded on the disks of the disk drive 8 or some material tapes recorded on one video tape cassette. It is conceivable that the material cut timecodes already exist.

Generally, when recording video and audio signals on a video tape cassette, a continuous time code from the recording start point to the recording end point is given from itself or another apparatus (for example, editing controller). Will be recorded. Therefore, when recording a desired material cut from a plurality of video tape cassettes on a disc, naturally, the time code of one material cut and the time code of another material cut overlap.

Therefore, if the timecodes of the material are duplicated, if the material is accessed by the timecode,
For example, there is an inconvenience that editing cannot be performed normally, such as when the intended material cannot be edited.

Of the video and audio signals recorded on one or a plurality of video tape cassettes, the video and audio signals of a desired length from the position of an arbitrary time code are used as one material. When the operation of recording the material on the disc is repeated, there is almost no possibility that the time codes among the plurality of materials recorded on the disc are all continuous.

For example, of the video and audio signals recorded on one video tape cassette, time code 0
0H (hour), 00M (minute), 00S (second), 00F
(Frame) to time code 00H, 01M, 30
Video and audio signals up to S and 00F are specified, this is recorded on the disc as material A, and time code 01H and 0
Time code 01H, 03 from 0M, 00S, 00F
Specify video and audio signals up to M, 20S, 00F,
When this is recorded on the disc as the material B, the end time code of the material A and the start time code of the material B are not continuous.

That is, when the video and audio signals of a desired period are designated among the video and audio signals recorded on the video tape cassette, and the signals are recorded on the disk as a material, they are recorded on the disk. The time code between the materials is not continuous unless the material is specified so that the time code is continuous between the plurality of created materials.

Therefore, at the time of editing, the VTR 2 on the reproducing side
To access the recorded video and audio signals of the video tape cassette set to, for example, the video and audio data recorded on the disc can be specified only by specifying any other time code from any time code. Will be very difficult to access.

Therefore, by specifying a file name, as is done in a personal computer, for example,
It is conceivable that the time code may not be used at all, for example, by reproducing the video and audio data recorded on the disc.

However, editing and managing video and audio signals without using the time code is technically difficult at present (alternative to the time code is difficult to realize). Further, it is almost impossible to realize even from a practical point of view (time code is widely used in general and business).

If the capacity of the disc is increased and all the video and audio signals from the VTR 2 on the reproducing side are continuously recorded on the disc, the time code of the video and audio signals recorded on the disc is Since the continuity is not lost, the material can be designated by the time code at the time of editing, as if the VTR 2 on the reproducing side is accessed.

However, recording all the video and audio signals on the disk in this way not only consumes the recording capacity of the disk, but also uses a hard disk drive having the maximum recording capacity (for example, 1 GByte) as a SCSI. Even if a maximum of eight devices are connected via the interface, the recording capacity of the video tape cassette is far short, depending on the recordable time of the video tape cassette. In other words, it is almost impossible to record all the video and audio signals recorded on the video tape cassette on the disk, and also record the video and audio signals that are not likely to be used on the disk. Not only wastes the recording capacity of the disk, but also cannot improve access to video and audio data.
This also concerns the following issues.

When the video and audio data reproduced from the disc is edited by a DME or a mixer,
If the editing is to be redone, the original material is searched from the disc and the editing is redone again. Making it possible to access the original material at higher speed when searching from the disc is an essential issue in editing work, and there is a demand for a device that can search the material at higher speed. It is the current situation.

Therefore, the video and audio signals from the reproducing VTR 2 are recorded on the disc as much as possible, and only the video and audio data used for editing are erased from the video and audio data recorded on the disc. It is also conceivable to record the video and audio signals from the VTR 2 on the reproducing side again in the recording area on the disc which has become recordable. According to this, by erasing the edited video and audio data one by one, the recording capacity of the disc may be small, and the recording area of the disc may be effectively used.

However, if it becomes necessary to reuse the video and audio data that has been erased from the disc by re-editing, the video and audio signals from the reproducing VTR 2 are erased and recorded again. It will have to be recorded in the area. In other words, the method of erasing the video and audio signals used for editing one by one from the disc increases the internal processing and the work performed by the operator who performs the editing, which is not preferable from the viewpoint of editing efficiency.

The present invention has been made in consideration of the above points, and when a medium for recording video and audio is a disk, the disk can be used efficiently and the management of the video and audio data recorded on the disk is possible. The recording and reproducing process using the video and audio data recorded on the disc can be simplified and the editing process can be performed at high speed, thereby making it possible to simplify and downsize the device or system. An attempt is made to propose a reproducing method and its apparatus, an editing method and its apparatus.

That is, the material ID generation unit 26 gives a material ID “V048-00” having a value larger than the upper digit of the material ID given to the material that has not been subjected to the effect processing. Here, the lower digit is set to "00" because it is the first material obtained by performing the special effect and the audio processing. Therefore, if this material is processed multiple times, twice or three times, the material ID generation unit 2
In 6, the lower digit is set to “01” and “02”.

Next, the address search unit 20 changes the memory unit 2
By referring to the address management table 29 of No. 7, the address of the smallest value in the free area on the disk set in the disk drive 57 is detected, and the detected address data is supplied to the control unit 32. Then, the data length discriminating unit 24 obtains the recording data length based on the time code at the start and end of the process stored in the memory 28 of the memory unit 27.

Then, the control unit 32 controls the material ID generation unit 2
The material ID “V048-00” from No. 6 is stored in the address management table 29 of the memory unit 27, and the address data supplied from the address search unit 20 is used as a recording start address in the address management table 29 of the memory unit 27.
Then, the data length data from the data length discriminating unit 24 is stored in the address management table 29 of the memory unit 27, and the time code data at the start of processing stored in the memory 28 of the memory unit 27. Is read, and the read time code data is stored in the address management table 29 as material recording start time code data. still,
As for the reel ID data, when the reel ID data of the material as the A roll and the reel ID data of the material as the B roll are the same, the reel ID data is stored in the storage area of the reel ID data of the address management table 29. After reading both reel ID data from the address management table 29, the material ID “V0
It is stored in the reel ID storage area of 48-00 ".

Simultaneously with the above processing, the control section 32 supplies the recording start address data and the recording data length data of the material ID "V048-00" to the disk controller 56 via the input / output terminal 38. The disk controller 56 controls the disk drive 57, and the video data as the A roll and the video data as the B roll, which are read from the buffer memory 81 of the input interface circuit 53, are read by the disk set in the disk drive 57. Record the processed part of the.

As a result, as shown in FIG. 10, the video data as the A roll of the material ID "V025-01" and the video data as the B roll of the material ID "V026-02" are subjected to the special effect processing. The resulting processed video data is recorded on the disc. Along with this, a new material ID "V048-" is added to this video data.
00 ”and management information such as a recording start address, recording data length, material start time code, reel ID, etc. are added to the material ID“ V049-00 ”which is the special effect processing portion of the video data Vd shown in FIG. Video data, material ID
Video data of "V050-03", material ID "A048
-00 ”voice data and material ID“ A072-00 ”
The audio data of is also recorded on the disc in the same manner as described above.

Therefore, as compared with the case where the AB roll editing is performed with the material as the A roll and the material as the B roll and all the edited video and audio data obtained as a result are recorded on the disc, The recording capacity can be greatly saved.

Next, the part on which the special effect and the sound processing are applied is recorded on the disc separately from the original material, and new management information is added to the part on which the special effect and the sound processing are applied, so that the address can be obtained. When the video data Vd and the audio data Ad are registered in the management table 29, the registered video data Vd and the audio data Ad are read from the disk, and the read video and audio data are set in the recorder 62 shown in FIG. A case of recording on a video tape cassette will be described. Video data to be recorded Vd
The audio data Ad and the video data Vd and the audio data Ad given the material ID shown in FIG. 10 will be described as an example.

The video data Vd and the audio data Ad are reproduced from the disc in the order shown in FIG. 10, and the reproduced video data Vd and the audio data Ad are set in the recorder 62 shown in FIG. If you want to record to a video tape cassette, the following procedure is required.

That is, the operator sequentially designates the material IDs of the video and audio data recorded on the disc through the operation panel 66 of the operation unit 65 so that the material ID data shown in FIG. Create a file. This file is stored in the medium set in the medium drive 64e of the editing controller 64. The operator can create the file by sequentially inputting a plurality of material ID data using the operation panel 66 of the operation unit 65 so that an intended editing result can be obtained.

The editing controller 64 reads out the file data of the file name input by the operator, that is, a plurality of material ID data from the medium of the media drive 64e, and temporarily reads the plurality of read material ID data.
Stored in AM64d and stored multiple material IDs
The data is supplied to the system controller 63. The control unit 32 of the system controller 63 stores the material ID data supplied from the editing controller 64 via the input / output terminal 33 in the memory 28 of the memory unit 27.

Subsequently, the control unit 32 controls the same material I as the plurality of material ID data supplied from the editing controller 64.
The recording start address data, recording data length data, and material start time code data of D data are read from the address management table 29 of the memory unit 27, and the read recording start address data, recording data length data, and material start time code data are associated with each other. Each material I of memory 28

The control unit 32 controls the material ID "V025-0.
The new recording data length of the material ID “V025-01” is obtained from the recording data length given to the 1 ”and the recording data length of the material ID“ V048-00 ”which is the special effect processing part. The new recording data length of “V025-01” will be described with reference to FIG.
It is the number of sectors consumed by the video data from the beginning of "-01" to the beginning of the material ID "V048-00".

Next, the control unit 32 controls the material ID "V048".
The time code of the last part of the material ID “V048-00” is obtained from the material start time code and the recording data length given to −00 ”, and the obtained time code and the material ID“ V026-02 ”are given. The new recording data length and recording start address of the material ID “V026-02” are obtained from the recorded material start time code, and the newly obtained recording data length and recording start address are set to the material “V0
26-02 "is rewritten as the recording data length and the recording start address given to" 26-02 ".
Use the newly obtained time code as the material ID “V026-0
It is rewritten as the material start time code given to 2 ".

As a result, the memory 28 of the memory unit 27 is
Material ID “V0 among the multiple material IDs stored in
The recording data length data assigned to 25-01 ", the recording start address assigned to the material ID" 048-02 ", the recording data length data, and the material start time code are rewritten respectively. However, the address management table 29 The management information stored in the file remains unchanged because the operator can sequentially specify the material IDs in the same manner as described above, and create a file for editing any number of times.

By the above procedure, the video data before and after the special effect processing portion, the recording start address, the recording data length data and the material start time code data which are respectively given to the audio data before and after the audio processing portion are stored in the memory. Rewritten on 28. Therefore, in the example of FIG. 10, the material ID
The recording data length data of “V028-01” is rewritten, the recording start address of the material ID “V033-03”,
The recording data length data and the material start time code are rewritten, the recording data length data of the material ID "V033-05" is rewritten, the recording start address, the recording data length data and the material start time code of the material ID "V034-02" Is rewritten, and the material ID is “A026-01”

The recording start address, recording data length data and material start time code data of "A034-01" are rewritten.

By the way, in FIG. 10, the material ID "A
Unlike other parts, the sound data of "060-02" has material ID "A048-0" as a sound processing part at both ends thereof.
0 "and" A072-00 "are arranged. Therefore, originally, the data length of the audio data of the material ID" A060-02 "is the material ID" A048-00 "and" FA ".
Assuming that the length is the sum of the data lengths of "072-00", first, the material ID "048-00" and the material ID
Focusing on “A060-02”, the material ID “A060-0
The recording start address, the material start time code, and the recording data length of 2 ”are obtained, and the obtained recording start address, the material start time code, and the recording data length are used as the material ID
The recording start address of "-02", the material start time code and the recording data length are rewritten, and then the material ID "A0
The new recording data length of the material ID "A060-02" is obtained by focusing on the material 60-02 "and the material ID" A072-00 ".

By the above processing, the recording start address, the recording data length data, the material start time code data, which are respectively given to the plurality of material ID data, on the other hand, the edit controller 64 indicates to the recording machine 62 that recording is temporarily stopped. Provides a recording / reproduction control signal. As a result, the recorder 62
Is in a recording suspended state.

Control unit 32 of system controller 63
Reads the recording start address data of the material ID “V025-01” of the video data to be reproduced first from the memory 28 of the memory unit 27, and the read recording start address data is input via the input / output terminal 38 to the disk controller 56. Supply to. Subsequently, the control unit 32 of the system controller 63 reads out the recording start address data of the material ID “A052-02” of the audio data to be reproduced first from the memory unit 28, and outputs the read recording start address data to the input / output terminal.

Further, the control section 32 of the system controller 63 supplies the switching control signal to the switch 61 via the output terminal 40, and the movable contact 61 of the switch 61 is supplied.
d is connected to the fixed contact 61b. Then, the calculation unit 30 of the system controller 63 obtains a value (final address) L obtained by adding the recording start address data and the recording data length data for each material to be reproduced, and obtains the reproduction end point of one material, As a result, the disk drive 57 is controlled via the disk controller 56.

The disk controller 56 controls the disk drive 57 based on the recording start address data supplied from the system controller 63. As a result, the material I from the disk of the disk drive 57 is initially used.
The video data of D "V025-01" is reproduced, and then the audio data of material ID "A052-02" is reproduced.
The reproduced video data of the material ID “V025-01” and the reproduced audio data of the material ID “A052-02” are supplied to the output interface circuit 58 via the disk controller 56 and the bus 54, respectively.

The editing controller 64 supplies a recording / reproducing control signal indicating the start of recording to the recording machine 62, and changes the recording machine 62 from the recording paused state to the recording state. As a result, the video and audio data supplied to the recorder 62 is recorded in the video tape cassette set in the recorder 62. still,
Since the video data and the audio data are sequentially reproduced from the disc, there is a time lag, but the disc controller 56 controls the disc drive 57, the system controller 63 controls the FIFO memory 91 of the output interface circuit 58, or the output interface circuits 96 and 1.
It is supplied to the recording machine 62 after the timing is controlled by the control of 00. By the procedure described above, the video and audio data to which the other material IDs shown in FIG. 10 are added are sequentially recorded in the video tape cassette set in the recorder 62. Therefore, video tape
The edited video and audio data is recorded in the cassette.

As described above, in this example, the reproducing device 51
Video and audio data reproduced from, or a desired portion is cut from externally input video and audio data, and video and audio data as material obtained by cutting are recorded on the disc, respectively, and the video and audio recorded on the disc are recorded. Management information such as a material ID, a recording start address, a recording data length, a material start time code, and a reel ID is added to each data, and this management information is assigned to each material in the address management table 29.
Since it is stored in the memory, it is possible to easily manage the material, and it is possible to perform editing work using time code. Can be well served.

When changing the length or the like of the material once recorded on the disc, the material itself is not recorded again on the disc, but new management information is added to the changed material, Since the new management information is stored in the address management table 29, the recording capacity of the disc can be greatly saved, and the video and audio data itself does not have to be recorded again on the disc. , Can be done efficiently.

When the two materials are subjected to special effects and audio processing, only the video and audio data of the processed parts are newly recorded on the disc, and the management information is added to the newly recorded materials. As a result, the recording capacity of the disc can be greatly saved as compared with the case where all the video and audio data including those other than the processing portion are recorded on the disc.

Also, an edit file can be easily created by inputting the material ID of the material to be edited, and the edit controller 64 and the system controller 63 are automatically moved from the disk by designating the file. Since it is possible to access and record the reproduced material in the recorder 62, it is possible to improve the editing efficiency, simplify the editing work, and improve the editing accuracy.

[Embodiment 2] In the above-mentioned Embodiment 1, the video and audio data as the material is recorded with the sector as a delimiter. Generally, the recording capacity of one sector of the disc is 256 bytes. Since it is often set to 512 bytes, there is a high possibility that the video and audio data as a material will not fit in just N sectors. Therefore,
When there is a surplus in the last recording sector, byte number data indicating how many bytes of video and audio data are recorded may be obtained from the last recording sector number and added to the address management information. In this case, the last recording sector number of the first material becomes the recording start sector number of the next material, but the byte count data from the last recording sector of the first material is stored in the address management information. For example, it is possible to use the disk more effectively without generating an unused area in the sector.

[Third Embodiment] In the first embodiment, after the edit file is designated, the system controller 63
The case has been described where the corresponding management information is read from the address management table 29, the read management information is changed, and the disc is accessed based on the changed recording start address and recording data length. The edit controller 64 may supply the edit file data to the system controller 63 after the edit file is created by the controller 64, the management information is obtained from the system controller 63, and the obtained management information is changed.
