Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording / playback apparatus suitable for application to a disk recording / playback apparatus called, for example, a DVD (Digital Video Disc or Digital Versatile Disc) recorder, and more particularly to an apparatus capable of editing recorded video.
[0002]
[Prior art]
In recent years, various recording / reproducing apparatuses for recording video data and audio data using an optical disk as a recording medium have been developed. For example, as a recording medium for recording video data, a disc-shaped recording medium developed based on the DVD standard such as DVD-R or DVD-RW is used, and about 2 hours of video data is recorded on one disc. Various disc recording / reproducing apparatuses for recording and reproducing have been commercialized.
[0003]
In the case of this type of disc recording / reproducing device, unlike a VTR device using a video tape, an arbitrary recording position on the disc can be easily accessed, so that editing work can be performed using video data recorded on the disc. It has the advantage that it can be easily performed. That is, it is relatively easy to reproduce only a necessary part or to not reproduce an unnecessary part from one video program recorded on the disc.
[0004]
Further, the data edited in this way (data relating to editing points such as a reproduction position and a reproduction unnecessary position; hereinafter, this data is referred to as editing data) is stored in some storage means, and the editing data is stored in the editing data. Based on this, it has also been proposed to control playback from another playback device. Specifically, for example, a video camera recorder capable of recording and playing back a captured video on a medium such as a video tape or a disk is prepared, and the video camera recorder is connected to a disk recording / playback apparatus. At this time, the video camera recorder is connected so that the playback state (playback start, stop, etc.) can be controlled by the disk recording / playback apparatus. First, the video data recorded on the medium in the video camera recorder is reproduced and recorded on the disc as it is by the disc recording / reproducing apparatus.
[0005]
Thereafter, the disc recording / reproducing apparatus performs editing while reproducing the disc on which the video data is recorded, and the editing data is stored in the memory in the disc recording / reproducing apparatus.
[0006]
When the edited data is obtained, the disc recording / playback device prepares another disc on which no video data is recorded, plays back the video data recorded on the medium in the video camera recorder again, and To the other disc. However, at this time, the playback position of the video camera recorder is controlled based on the edit data, and the edited position is recorded on the disc.
[0007]
By doing this, the edited video program will be recorded on the disc, and if the device that sends the video does not have an editing function or if a separate editing device is not prepared, Edit video programs. Patent Document 1 discloses a recording / reproducing apparatus that can perform such editing work.

[0009]
[Problems to be solved by the invention]
By the way, since a disk recording / reproducing apparatus such as a DVD recorder can replace a disk as a recording medium, even if editing data is stored in the memory of the disk recording / reproducing apparatus, the editing data and the apparatus are attached to the editing data. The disc video program may not match, and in such a case, editing will fail. Conventionally, however, the process of matching the edit data and the disk in such a case is left to the user's selection operation, and when the user mounts the wrong disk, the failure cannot be prevented.
[0010]
Also, with respect to a playback device (video camera recorder in the above example) that sends out the original video program, if the prepared video program does not match the video program edited by the disk recording / playback device, it will eventually be stored on the disc. When dubbing, the program will be completely different from the program edited by the user and will fail. However, even if such a failure occurs due to a mismatch on the sending side, another video program is recorded by the user by mistake. It was not possible to prevent it when the medium was installed.
[0011]
SUMMARY OF THE INVENTION An object of the present invention is to enable editing of target correct video data when editing is performed by a device on the side where video data is dubbed.
[0012]
[Means for Solving the Problems]
In the present invention, when video data transmitted from the outside is recorded on a recording medium, the specific data necessary for specifying the video data is stored and the video data recorded on the recording medium is edited. In the case where the storage means for storing the editing data is provided, recording is performed on the recording medium attached to the medium attaching means before editing the recording medium attached to the medium attaching means. The predetermined data stored in the storage unit is compared with specific data stored in the storage means, and when there is data that matches any of the specific data, this is displayed. .
[0013]
By doing in this way, when the video indicated by the specific data matches the video recorded on the recording medium, this is displayed, and the video that can be edited can be surely seen from the display.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0015]
In this example, the present invention is applied to a DVD recorder that can perform recording and reproduction on DVD-R, DVD-RW, and DVD + RW recording media, which are disc-shaped recording media developed based on the DVD standard. It is as. You may comprise so that recording and reproduction | regeneration of the discs (DVD-RAM etc.) related to DVD standards other than this can be performed.
[0016]
FIG. 1 is a block diagram showing a configuration example of a disc recording / reproducing apparatus which is a DVD recorder of this example. First, the recording system of the disk recording / reproducing apparatus 10 will be described. The disk recording / reproducing apparatus 10 of this example is configured to receive a broadcast wave obtained via the connected antenna 1 by the tuner 11. The video signal and audio signal obtained in this way are supplied to the analog / digital converter 14 via the changeover switch 12 and converted into digital data. The tuner 11 may be a tuner that receives satellite broadcast waves in addition to a tuner that receives terrestrial waves. The reception channel in the tuner 11 is controlled by the control unit 30 that controls the operation of each unit of the recording / reproducing apparatus 10. If the broadcast wave received by the tuner 11 includes auxiliary data such as electronic program information called EPG (Electric Program Guide), the auxiliary data is sent to the control unit 30. The control unit 30 stores the electronic program information in the memory 31 connected to the control unit 30 when the electronic program information is supplied. Here, the memory 31 is configured by a flash memory which is a nonvolatile memory.
[0017]
The digital data converted by the analog / digital converter 14 is supplied to an MPEG (Moving Picture coding Experts Group) encoder 15 to obtain video data and audio data encoded in the MPEG2 system. Video data and audio data encoded in the MPEG2 format are supplied to the recording / playback processing unit 18, and recording processing for recording on the disk 21 mounted on the disk tray 20 is performed by the optical pickup 19. The disc recording / reproducing apparatus 10 of this example has a configuration in which the disc tray 20 can be opened and closed by a loading mechanism, and a configuration in which the disc can be detachably mounted on the tray (that is, a configuration in which the disc can be replaced).
[0018]
Data is recorded on the disk 21 placed on the tray 20 by laser light emitted from the optical pickup 19 while being rotated by a spindle motor 22.
[0019]
The disc recording / reproducing apparatus 10 of this example also includes an input terminal 13 to which analog video signals and video signals are input, and a port 16 to which a serial bus line is connected. The resulting signal can also be recorded. The analog video signal and video signal obtained at the input terminal 13 are supplied to the analog / digital converter 14 via the changeover switch 12 and can be recorded instead of the output of the tuner 11.
[0020]
Here, the port 16 to which the serial bus line is connected is a port to which an IEEE (The Institute of Electrical and Electronics Engineers) 1394 bus line is connected, and the interface unit 17 performs transmission processing and reception processing of the IEEE 1394 method. Is executed. The interface unit 17 extracts video data and audio data from the data obtained via the bus line, supplies the data to the MPEG encoder 15, and performs recording processing as video data and audio data encoded in the MPEG2 system. Do. If the video data and audio data obtained via the bus line are already encoded in the MPEG system, the encoding by the MPEG encoder 15 is not performed.
[0021]
In addition, the IEEE 1394 bus line has a configuration in which various control data can be bidirectionally transmitted separately from stream data such as video data and audio data, and control data obtained from the outside via the port 16 to the interface unit 17. Is supplied to the control unit 30. The control data generated by the control unit 30 can also be supplied to the interface unit 17 and sent from the port 16 to the bus line side. As the control data transmitted via the bus line, for example, there is data for controlling the reproduction of the video reproducing apparatus connected via the bus line. It is also possible to detect the operating state of the counterpart device by transmitting control data.
[0022]
In addition, when video data received via the port 16 is recorded on the disc 21, title data generated under the control of the control unit 30 is recorded on the disc. The title data recorded on this disc may be stored not only on the disc but also simultaneously in the memory 31 connected to the control unit 30. Details of the title data will be described later.
[0023]
Next, the reproduction system of the disk recording / reproducing apparatus 10 of the present example will be described. Data recorded on the disk 21 can be reproduced by detecting the return light of the laser light emitted from the optical pickup 19. The output of the laser beam irradiated from the optical pickup 19 is different between the reproduction and the recording, and is a relatively strong output that can be recorded on the signal recording layer of the disk at the time of recording, and is read without changing the signal recording layer at the time of reproduction. Can be a relatively weak output.
[0024]
Based on the output from the optical pickup 19, the data reproduced from the disc is detected by the recording / reproducing processor 18, and the reproduced data is supplied to the MPEG decoder 23. The MPEG decoder 23 performs a process of decoding the video data and audio data recorded on the disk by the MPEG method, and supplies the decoded video data and audio data to the digital / analog converter 24 for analog video. Signal and audio signal.
[0025]
The analog video signal and audio signal converted by the digital / analog converter 24 are supplied to the output terminal 27 via the mixer 25. The output terminal 27 is connected to a video display device such as a television receiver and displays video on the display device. The mixer 25 is a circuit that mixes a signal for displaying characters, graphics, and the like generated by the display processing unit 26 on a screen with a reproduced video signal. Under the control of the control unit 30, the display processing unit 26 not only performs a process of displaying the recording state, the reproduction state, etc. with characters and numbers, but also displays a screen necessary for the operation when setting various modes, for example. . For example, the display processing unit 26 generates a display screen for performing a project list display described later.
[0026]
The main body of the disk recording / reproducing apparatus 10 is also provided with a display panel 32 so that a relatively simple display of the operating state, recording time, reproduction time and the like can be performed. Further, an operation key 33 is provided so that a command based on the operation of the operation key 33 reaches the control unit 30. In addition to the key 33 attached to the main body of the recording / reproducing apparatus 10, the recording / reproducing apparatus 10 can also be controlled by a remote control signal from a remote control device (not shown).
[0027]
Further, the disc recording / reproducing apparatus 10 of this example is configured so that the recorded video can be edited with respect to the disc 21 on which the video data and the like are recorded by the recording / reproducing apparatus 10, and the edited data is transmitted to the control unit. The data can be stored as project data in a memory 31 connected to 30. The edit data here is, for example, data such as the start point and end point of a section (scene) where playback is performed in each video program (or the start point and end point of a section where playback is not performed) and the playback order of each scene. It is.
[0028]
Next, a description will be given of a processing example in the case where a video program transmitted from the outside is recorded on the disc 21 using the disc recording / reproducing apparatus 10 configured as described above, and then the recorded video program is edited. To do. Here, for example, as shown in FIG. 2, a video camera recorder 40 is prepared, and an IEEE 1394 port 41 prepared in the video camera recorder 40 is connected to the port 16 of the disc recording / reproducing apparatus 10 of this example. Thus, the video program recorded on the video tape cassette mounted in the video camera recorder 40 is dubbed onto the disc by the disc recording / reproducing apparatus 10 for editing. The port 41 of the video camera recorder 40 and the port 16 of the disc recording / reproducing apparatus 10 are connected by the cable 2 of the IEEE 1394 standard. That is, one end 2 a of the cable 2 is connected to the port 41 of the video camera recorder 40 and the other end 2 b of the cable 2 is connected to the disc recording / reproducing apparatus 10.
[0029]
In this case, the video camera recorder 40 is a model that can control playback operations and the like by control data transmitted from the disk recording / playback apparatus 10 via the cable 2. As described above, the disc recording / reproducing apparatus 10 has a configuration in which the disc tray 20 can be opened and closed, and the disc can be exchanged.
[0030]
Next, after connecting as shown in FIG. 2, a video program (video data and audio data) recorded on a video tape cassette mounted on the video camera recorder 40 is stored in the disk mounted on the disk recording / reproducing apparatus 10. The flow of processing for editing the video program recorded on the disc and recorded on the disc will be described with reference to FIG.
[0031]
First, as shown in FIG. 3, the disc recording / reproducing apparatus 10 is a disc on which no video is recorded (or a disc having an unrecorded area having a capacity capable of recording a video program to be recorded; Prepare a disk and install it. Here, this disk is called disk A. Then, the video program recorded on the video tape cassette mounted on the video camera recorder 40 is reproduced, and the reproduced video data and audio data are sent to the disk recording / reproducing apparatus 10 for dubbing to be recorded on the disk A ( Step S11). Details of the dubbing process will be described later with reference to the flowchart of FIG. 4. Here, the time at which recording (dubbing) is started and the playback length of the video program are controlled in the disk recording / playback apparatus 10. The unit 30 determines that the time and reproduction length data are stored (saved) as part of the project data in the memory 31 (step S12). The time here is, for example, data of year / month / day / hour / minute / second.
[0032]
Further, not only the video data constituting the video program but also the title data of the video program is recorded on the disc A. As the title data here, time and reproduction length data obtained as part of the project data are recorded. When data relating to other video programs (for example, specific title names) is obtained, these data may also be recorded on the disc as title data.
[0033]
Thereafter, when editing the video program recorded on the disk A is started (step S13), a list of projects stored in the memory 31 of the disk recording / reproducing apparatus 10 is displayed. At this time, using the title data associated with the video program recorded on the disc A at that time and the data stored in the memory 31, the video program recorded on the disc is stored in the memory 31 as one of the project data. A process for determining whether the data matches the data stored as a section is performed, and based on the determination, a corresponding display is performed during the project list display (step S14). The determination processing here is performed in order to prevent the editing operation from being mistakenly performed when the disk A is replaced with another disk before the editing operation is performed. Details of this determination processing will be described later with reference to the flowchart of FIG.
[0034]
Then, the project selected from the project list display can be shifted to the actual editing work (step S15). In the editing work, for example, the start point and end point of each scene to be played back in the video program, the playback order of each scene, etc. are set, and the set editing data is stored in the memory 31 as project data. (Step S16). As will be described later, in step S15, the actual editing work can be limited to projects for which a match is detected in the list of projects.
[0035]
Thereafter, the disk A is taken out from the disk tray 20 of the disk recording / reproducing apparatus 10, and another recordable disk B is prepared and mounted on the disk tray 20. When there is an operation for starting dubbing of the edited video program, the control unit 30 of the disc recording / reproducing apparatus 10 sends control data for reproducing the tape to the video camera recorder 40 (step S17). The video camera recorder 40 reproduces the tape cassette based on the reception of the control data, and sends the reproduction data to the disc recording / reproducing apparatus 10. The disc recording / reproducing apparatus 10 starts recording on the disc B when it is determined that the recording is the in point from the comparison between the time code added to the reproduced data sent and the edited data, and the recording is started at the out point. When this happens, the recording is stopped (step S18). The time code is, for example, a code sent in units of frames of reproduced video data.
[0036]
By doing so, the edited video program is recorded on the disc B. As long as the project data is not deleted, another disk C, disk D,... Are prepared using the project data stored in the memory 31, and each disk C, D is prepared in the same manner as the disk B. It is also possible to dubb video programs that have been sequentially edited.
[0037]
Next, details of the processing at the time of the first dubbing to the disk A shown in FIG. 3 will be described with reference to the flowchart of FIG. In this flowchart, the disk is a disk mounted on the disk recording / reproducing apparatus 10 side, and the tape is a video tape in a video tape cassette mounted on the video camera recorder 40. First, when there is an instruction to start dubbing by a user operation (step S21), the control unit 30 performs a recording pause process for the disc (step S22). At this time, the current time data is stored in the memory 31 connected to the control unit 30 as a part of the project data (step S23).
[0038]
Thereafter, a playback start command is sent to the video camera recorder 40 to start data playback (step S24), and at the same time, recording of the disk is started (step S25). When the control unit 30 of the disc recording / reproducing apparatus 10 detects the stop of the tape (step S26), the recording of the disc is stopped (step S27), and the reproduction length of the video recorded at this time is set as a part of the project data. Is stored in the memory 31 (step S28).
[0039]
Next, the discriminating process (corresponding to the discriminating operation in step S14 in FIG. 3) of the video program recorded on the disc, which is executed before the editing operation is performed on the disc thus recorded, is shown in FIG. This will be described with reference to the flowchart of FIG. First, the user performs an operation for displaying a list of projects (step S31). The project list display is executed based on the project data stored in the memory 31 of the disk recording / reproducing apparatus 10.
[0040]
When the list display is instructed, the control unit 30 sequentially sets the project number I to be read from the memory 31 (step S32), and reads the set I-th project data from the memory 31 (step S33). Next, the title data recorded on the disc loaded at this time is sequentially read (step S34). Here, the J-th title data is read from the disc (step S35). Then, the date (year / month / day / hour / minute / second) indicated by the I-th project data is compared with the date (year / month / day / hour / minute / second) indicated by the J-th title data (step S36). If the comparison does not match, the process returns to step S34 to read another title data from the disc. If a match is detected in step S36, the playback length indicated by the I-th project data is compared with the playback length indicated by the J-th title data (step S37). If the comparison does not match, the process returns to step S34 to read another title data from the disc. In this way, all the title data recorded on the disc are sequentially compared with the project data that is a candidate at that time. Note that, as the match determination in step S36, the match determination may be performed with a certain error range (for example, about ± several seconds) instead of detecting a complete match in units of seconds.
[0041]
If a match is also detected for the playback length in step S37, a display indicating that the title matches the project is displayed in the project list (step S38), and the process returns to step S32. Then, another project data stored in the memory 31 is read out, and the same processing from step S33 to step S38 is performed on the read project data.
[0042]
When all the project data stored in the memory 31 is read in step S32, the matching process is terminated (step S39).
[0043]
FIG. 6 is a diagram showing an example of a project list displayed on the screen of a display device connected to the disc recording / reproducing apparatus 10. In this example, the project list is displayed as a “DV edit list”, and four project data are stored in the memory 31 as an example. That is, as an example of performing four project displays a, b, c, and d based on four project data. Here, in each project display a to d, a title inputted in advance is displayed in characters or the like. In addition, the total playback length for each project and the project editing date are displayed. For unedited projects, the date recorded on the disc is displayed.
[0044]
In the display example of FIG. 6, in the process shown in the flowchart of FIG. 5, two projects (corresponding to project displays b and c) out of the four project displays a to d are loaded at this time. This is a case where the title data matches with the title data recorded in. At this time, a mark e indicating a disk is displayed at the head of the two project displays b and c. Note that the condition for displaying the mark e indicating the disc is a video program dubbed onto the disc by the dubbing process as described above, and a disc on which the original video program that has not been edited is recorded is inserted. It is a case.
[0045]
As shown in FIG. 6, the process of selecting the project on which the mark e indicating the disk is displayed is performed by the user operation, and the user operation for selecting the determination key f on the screen is performed. Once played, you can move on to editing. It should be noted that when selecting a project, it may be restricted so that only projects displaying a mark e indicating a disc can be selected. Alternatively, when a project for which the mark e indicating the disk is not displayed is selected by the user operation, for example, “the corresponding disk is not loaded” is displayed to prompt the user to perform an erroneous operation. You may do it.
[0046]
In this way, it is possible to determine whether the project data stored in the memory 31 on the disc recording / reproducing apparatus 10 side matches the title data recorded on the disc mounted on the disc recording / reproducing apparatus 10 at that time. Editing work based on project data is performed, and it is possible to effectively prevent erroneous editing work.
[0047]
In the example described so far, when displaying a list of projects, the project data is compared with the title data recorded on the disc. However, it is recorded on the tape cassette on the video camera recorder 40 side. Also for the video program, it may be determined whether or not it matches the video program at the time of the first dubbing, and this may be displayed or editing may be restricted.
[0048]
FIG. 7 is a diagram showing a processing example in this case. In FIG. 7, the same step numbers are assigned to the portions corresponding to the processing shown in FIG. 3, and the processing up to the disc A discriminating processing up to step S14 is exactly the same as the processing of FIG. However, at the time of the first dubbing (step S11), the control unit 30 of the disc recording / reproducing apparatus 10 also obtains data necessary for specifying the video program reproduced on the video camera recorder 40 side, and It is necessary to memorize | store in the memory 31 as a part. As data necessary for specifying a video program reproduced on the video camera recorder 40 side, for example, there are data such as recording date and time code of video data.
[0049]
In the example of FIG. 7, the title data recorded on the disc A in step S14 is compared with the project data stored in the memory 31 on the disc recording / reproducing apparatus 10 side, and then attached to the video camera recorder 40. It is compared whether there is any video data recorded in the tape cassette that matches the project data stored in the memory 31 (step S19). If there is a match in this comparison, for example, when displaying a list of projects, a corresponding mark is displayed, and the user is allowed to select a project with the mark. Alternatively, if there is a matching project in the process, the matching project is automatically selected. Thereafter, the editing operation of step S15 is started.
[0050]
In this way, the editing operation can be performed more reliably by performing the matching determination of the video program prepared on the video transmission side. Note that the determination of the video program recorded on the tape cassette in step S19 in the process of FIG. 7 may be performed immediately before the edited dubbing in step S18.
[0051]
In the above-described embodiment, the present invention is applied to an optical disk recording / reproducing apparatus called a DVD recorder. However, the present invention can also be applied to other recording medium recording / reproducing apparatuses. For example, it may be a recording / reproducing apparatus using another disk-shaped recording medium such as a magneto-optical disk, or a recording / reproducing apparatus using a tape-shaped recording medium other than a disk or a recording medium using a semiconductor memory. Is also applicable. However, in any case, the recording medium needs to be configured to be detachable from the recording / reproducing apparatus main body.
[0052]
Further, in the above-described embodiment, recorded date (year / month / day / hour / minute / second) data and playback length data are used as data for detecting coincidence, but other data for specifying video data are used. Specific data may be used.
[0053]
In the embodiment described above, the video camera recorder as shown in FIG. 2 is used as a device for supplying video data or the like to the recording / reproducing apparatus. However, other video devices can be connected and used as a video signal source. Also good.
[0054]
【The invention's effect】
According to the present invention, this is displayed only when the video indicated by the specific data matches the video recorded on the recording medium, and editing is executed only for the correct video program based on the display. Thus, it is possible to effectively prevent a failure in which editing is performed on video data that is erroneously recorded on another medium.
[0055]
In this case, the editing process is executed only for the video data that is displayed as the matched video data, so that more effective erroneous editing prevention processing can be performed.
[0056]
Further, based on the editing data stored in the storage means, the reproduction control data for the video data supply source is generated, and the edited video data is stored in a recording medium different from the recording medium on which the video data is recorded. By performing the recording control, the edited video data can be recorded on the recording medium based on the control by the recording / reproducing apparatus.
[0057]
In addition, the video data supply source can be compared with the video data based on the specific data stored in the storage means, so that the video data can be verified more reliably. In addition, failure of editing and dubbing can be prevented.
[0058]
Further, since the specific data is data of the recording start time of the video data or the length of the video data, there is an effect that the verification can be surely performed using these data.
