Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information processing apparatus, method, and program, and more particularly, to an information processing apparatus, method, and program that enable editing to be started easily and quickly.
[0002]
[Prior art]
In recent years, due to the increase in capacity and the improvement in data transfer speed, an optical disk can be used as a recording medium of a video camera for broadcasting. For example, the recording capacity of an optical disc on which video and audio data are recorded by a blue-violet light emitting diode is about 23 GB in a single-sided, single-layer recording method, and the data transfer speed (recording rate) depends on the compression ratio. , But also reaches 50 Mbps or more.
[0003]
Depending on the shooting using such an optical disc and a broadcast video camera, the captured video may be compressed at a relatively low compression ratio so as not to cause deterioration in image quality. Also, proxy video data (low-resolution video data) compressed at a high compression rate and the like are recorded on the optical disc (Patent Document 1).
[0004]
Note that, with regard to the fetched voice, proxy audio data (voice data) having a high compression ratio is created as necessary in addition to the main line voice data.
[0005]
The proxy video data and the proxy audio data are data for performing so-called non-linear editing, which are generally performed in recent years, and are taken as a material for editing after being taken into a personal computer. That is, when performing non-linear editing on a personal computer or the like, the processing capacity is insufficient, so that the above-described main line data at a high recording rate cannot be directly used as a material for editing.
[0006]
As described above, editing performed using proxy video data as a material is sometimes referred to as proxy editing. This proxy editing is performed as a simple edit at a shooting site, for example. The result of the proxy editing is transmitted via a network to a studio device that creates final broadcast data, for example, separately from main line data delivered in a state recorded on an optical disk. Then, in the studio, main line data is edited based on the result of the proxy editing, and final video data for broadcasting is created.

[0039]
FIG. 1 is a diagram showing an optical disk device 1 to which the present invention is applied, and an optical disk 2 which is a recording medium detachable from the optical disk device 1.
[0040]
The optical disk device 1 is, for example, a device for performing simple editing at a shooting site, and has an optical disk 2 on which video and audio data captured by a video camera (not shown) is recorded. The photographed optical disc 2 records main video data (video data) as well as proxy video data that is converted to low-resolution data. Also, proxy audio data and the like obtained by further compressing the main line audio data (audio data) are created when necessary by the video camera and recorded on the optical disk 2.
[0041]
The proxy video data and the proxy audio data are used as proxy editing data for the user of the optical disc apparatus 1 as an editor to perform proxy editing (FIG. 2) or logging (FIG. 3). Hereinafter, when it is not necessary to individually distinguish the proxy video data and the proxy audio data, they are collectively referred to as proxy data.
[0042]
That is, as shown in FIG. 2, the video and audio captured by the video camera are relatively captured on the obtained captured optical disk 2 so that the video and audio are not deteriorated. A main video / audio data file 11 for storing main video data and main audio data with a large data amount and a high recording rate, which is obtained by compressing at a low compression ratio, and compressing the main video data and main audio data to a higher level. A proxy video / audio data file 12, a metadata file 13, and a still image list 14 that store proxy video data and proxy audio data with a small data amount and a low recording rate, which are obtained by compressing at a rate, are recorded. I have.
[0043]
When the optical disk device 1 on which such data is recorded is mounted in the state where an automatic copy mode described later is set, for example, the optical disk device 1 selects one of the main video / audio data file 11 through the still image list 14. When the proxy video / audio data file 12 is copied, the related metadata file 13 and still image list 14 are automatically read out without any operation from the user, and are a recording medium that incorporates them. Copy (record) to HDD (Hard Disk Drive).
[0044]
Thereafter, the user performs proxy editing using the proxy video data and the proxy audio data recorded on the HDD as a material (State 2).
[0045]
For example, in the proxy editing, using the proxy video data and the proxy audio data as a material, a video scene required for final editing in the final process is selected from one or more shot video scenes. An IN point and an OUT point are set for the selected video scene, and an operation of extracting a range of a video to be used is performed.
[0046]
The editing information 15 as a result of the proxy editing is transmitted, for example, via the Internet or the like to a device at an editing place where main line editing of main line video data and main line audio data is performed. The editing information 15 includes, for example, information indicating an IN point or an OUT point that specifies a range used in broadcasting or the like.
[0047]
On the other hand, the main line video / audio data file 11 is delivered to an editing place where main line editing is performed, for example, while being recorded on the optical disk 2. After that, the main line editing of the main line video / audio data file 11 is performed based on the editing result represented by the editing information 15 generated by the optical disk device 1 (State 3), and the final edited video data, audio Data is created.
[0048]
In such editing, since the proxy video data and the proxy audio data processed by the optical disc device 1 in the proxy editing are data having a relatively low recording rate and a small data amount, the optical disc device 1 performs the main editing. It is not necessary to prepare the processing capacity of the apparatus. In addition, by using the optical disk device 1, simple editing can be performed on the spot immediately after shooting.
[0049]
Further, for example, when the automatic copy mode is set, the user who performs proxy editing simply mounts the optical disk 2 on the optical disk device 1 and records the proxy video / audio data file 12 required for proxy editing. And the metadata file 13 and the still image list 14 can be recorded on the HDD of the optical disc device 1 along with the recording, so that proxy editing can be started easily and quickly. . That is, the user does not need to operate the optical disk device 1 after mounting the optical disk 2 on the optical disk device 1 to select a file to be taken by himself.
[0050]
The still image list 14 is obtained from predetermined metadata described in the metadata file 13 as described later in detail.
[0051]
FIG. 3 is a diagram illustrating an example of a data flow in the case where logging is performed instead of the above-described proxy editing at a shooting site. In State 2 of FIG. 3, data is read from the optical disk 2 to the optical disk device 1. Logging is performed using the proxy video / audio data file 12, the metadata file 13, and the still image list 14. This logging is an editing operation that is simpler than proxy editing, such as simply selecting only necessary video scenes.
[0052]
The editing reference information 21 indicating the result of the logging is transmitted to a device that performs the main editing, for example, via a network, and is referred to in the main editing (State 3) using main line video data and main line audio data as materials.
[0053]
In the above description, the metadata file 13 related to the proxy video / audio data file 12 is automatically copied along with the copying, but, for example, only one of the main video / audio data files 11 is recorded. When the main video / audio data file 11 is copied, the related metadata file 13 may be automatically copied. That is, the metadata file 13 may be automatically copied with the copying of any of the main line video / audio data file 11 and the proxy video / audio data file 12.
[0054]
FIG. 4 is a block diagram showing a configuration example of the optical disk device 1 that performs the above proxy editing and logging.

[0070]
Here, data recorded on the optical disc 2 will be described.
[0071]
First, terms related to data recorded on the optical disc 2 will be described.
[0072]
The “metadata” is supplementary information related to certain data such as video data, for example, and is used by an editor to confirm the contents of data or to search for a predetermined frame at the time of editing. For example, shooting date and time, shooting location, various memos, and the like are added to video data and the like as metadata. The metadata includes, for example, clip metadata added for each video data of one clip and frame metadata added for each frame. At least a part of the metadata recorded on the optical disk 2 is taken into the HDD 46 of the optical disk device 1.
[0073]
The “clip” is, for example, a continuous video section from the start of one recording to the end of recording by a video camera.
[0074]
FIG. 6 is a diagram illustrating an example of the structure of a directory (folder) of data recorded on the optical disc 2 and a file.
[0075]
As shown in FIG. 6, the ROOT directory stores a PROAV directory that stores video data corresponding to one program, and a configuration table data file that stores metadata of data in the PROAV directory.
[0076]
The PROAV directory stores an index file (INDEX.XML), a file in which the index file is copied (INDEX.RSV), a disc information file (DISCINFO.XML), and a file in which the disc information file is copied (DISCINFO.RSV). Is done.
[0077]
The index file is a file for managing recorded clips and edit lists over the entire disc, and is described in, for example, an XML (extensible Markup Language) -based language. The disc information file is a file that describes the attributes of the optical disc 2, the reproduction start position, and the like.
[0078]
The PROAV directory also stores a clip directory (CLPR) and an edit directory (EDTR).
[0079]
A directory corresponding to each clip is stored in the clip directory. The edit directory stores edit list data indicating the playback order and playback range of video data and audio data. In this edit list, information indicating the positions of the IN point and the OUT point set for the clip is described. A plurality of edit lists may be added to one clip.
[0080]
FIG. 7 is a diagram showing an example of a file stored in the clip directory (the directory whose name is “C0001” in FIG. 6). In FIG. 7, the parentheses added to the right of the file indicate the contents of the file and are not included in the file name.
[0081]
A file named “C0001C01.SMI” shown at the top of the clip directory is a set of independent multimedia objects (video or audio objects) with respect to time behavior, layout on the screen, or other information. Is a file describing, for example, SMIL (Synchronized Multimedia Integration Language) in association with the multimedia object.
[0082]
The file to which the name “C0001V01.MXF” is set is a file that stores main line video data.
[0083]
The files named “C0001A01.MXF” to “C0001A08.MXF” are files that store main line audio data. One channel of audio data is recorded in each file.
[0084]
The file with the name “C0001S01.MXF” is a file that stores proxy video data. That is, the proxy video data stored here is obtained by compressing the main line video data stored in the file named “C001V01.MXF” at a higher compression rate. This is the data of the recording rate.
[0085]
The file to which the name of “C0001M01.XML” is set is a file that stores clip metadata added to this clip (clip of “C0001”) and is described in an XML-based language.
[0086]
The clip metadata includes an essence mark, which is feature information of a frame, set for a predetermined frame constituting video data during shooting or after simple editing.
[0087]
For example, the frame in which the essence mark is set by the essence mark is a frame at which shooting is started, a frame at which shooting is completed, a frame at which a volume greater than a predetermined threshold is detected at the time of shooting, This indicates that the frame has been flashed during shooting. The essence mark is used, for example, when an editor specifies a certain frame at the time of editing.
[0088]
In addition, the clip metadata includes a still image list which is a list of information such as a time code which designates a frame representing the clip.
[0089]
For example, in editing performed later, the frames specified in the still image list are displayed as a list of still images (representative images) on the editing screen, so that the editor can easily grasp the contents of the clip. be able to. The frame specified by the still image list is, for example, the top frame of a clip, a frame on which an essence mark is set, and the like.
[0090]
The file with the name “C0001R01.BIM” is a file that stores the frame metadata set for each frame of this clip. In this example, the frame metadata is described in a BIM (binary format for metadata) format obtained by converting a file in an XML format into a binary format. Thus, the frame metadata is described in a file different from the clip metadata. Therefore, data necessary for editing, such as only clip metadata or only frame metadata, can be specified in file units.
[0091]
For example, as frame metadata, LTC (Linear Time Code) which is a time code characterizing video data of a frame in which frame metadata is set by predetermined time information such as year, month, day, hour, minute, and second. A user bit indicating the signal characteristics of the image signal of the frame, a UMID (Unique Material Identifier), which is the only ID set in the referenced data, which is the only ID in the world, and a GPS indicating the position where the image was captured by the video camera (Global Positioning System) information and the like.
[0092]
The file in which the name of “C0001I01.PPF” is set is a file in which information on the frame structure is described.
[0093]
Returning to the description of FIG. 5, the optical disk data reading unit 92 reads a proxy video data file, for example, “C0001S01.MXF” in FIG. 7 from the optical disk 2 on which various data are recorded in the above structure. A file to which a name is set and a file to which a name of “C0001M01.XML” which is a clip metadata file is set are read. As described above, the clip metadata file also includes the still image list.
[0094]
It should be noted that a file storing proxy audio data obtained by compressing main audio data at a high compression rate and an index file (FIG. 6) generated as necessary and recorded on the optical disk 2 are also appropriately read by the optical disk data reading unit 92. Is read.
[0095]
The data read by the optical disk data reading unit 92 is output to the control unit 93.
[0096]
Based on the index file supplied from the optical disk data reading unit 92 and the data supplied from the HDD data reading unit 95, the determination unit 111 of the control unit 93 records the proxy data recorded on the optical disk 2 also on the HDD 46. It is determined whether it has been performed. When determining that the proxy data recorded on the optical disk 2 is not recorded on the HDD 46, the determination unit 111 controls the optical disk data reading unit 92 to read the proxy data. At this time, the read proxy data is output from the control unit 93 to the writing unit 96 and stored in the HDD 46.
[0097]
If necessary, metadata such as clip metadata and frame metadata used in editing later are output from the control unit 93 to the writing unit 96 together with the proxy data, and are recorded in the HDD 46.
[0098]
The XML interpreting unit 112 of the control unit 93 interprets the file read from the optical disc 2 and described in the XML-based language, and outputs the interpretation result to the writing unit 96 and the representative image generating unit 97. As described above, the clip metadata file including the still image list is described in an XML-based language (FIG. 7), and the representative image is generated by the representative image generation unit 97 based on the interpretation result.
[0099]
The editing control unit 113 of the control unit 93 edits proxy data (proxy editing) based on an operation from the user.
[0100]
The mode setting unit 94 sets the automatic copy mode or cancels the setting, and outputs information indicating the state of the setting at that time to the optical disk data reading unit 92.
[0101]
The HDD data reading unit 95 reads data recorded in the HDD 46 and outputs, for example, information (management information such as an index file) for managing the data recorded in the HDD 46 to the control unit 93.
[0102]
The writing unit 96 includes various types of data used in editing, such as proxy data supplied via the control unit 93, interpretation results of a file described in an XML-based language, and a representative image generated by the representative image generating unit 97. The data is written to the HDD 46.
[0103]
Based on the proxy video data recorded in the HDD 46, the representative image generation unit 97 obtains data of a frame specified by the still image list and a frame (part of video data) in which an essence mark is set. The data is compressed by, for example, a JPEG (Joint Photographic Expert Group) method to generate a representative image. The representative image data generated by the representative image generation unit 97 is output to the writing unit 96. The representative image may be generated based on main line video data. For example, when a representative image is generated based on main line video data, the data of the frame is read by the optical disk data reading unit 92 and output to the representative image generating unit 97 via the control unit 93.
[0104]
Also, the representative image is not limited to a still image, and a video obtained from proxy data, for example, for a few seconds, may be displayed on the editing screen as a representative image.
[0105]
Next, the operation of the optical disk device 1 having the above configuration will be described.
[0106]
First, with reference to the flowcharts of FIGS. 8 and 9, the processing of the optical disk device 1 for copying data recorded on the optical disk 2 to the built-in HDD 46 will be described.
[0107]
This process is started when the photographed optical disk 2 is mounted on the drive 38 and the detection unit 91 detects that.
[0108]
In step S1, the optical disc data reading unit 92 sets the automatic copy mode based on the output from the mode setting unit 94 when the detection unit 91 detects that the photographed optical disc 2 is mounted on the drive 38. It is determined whether it has been performed.
[0109]
If the optical disc data reading unit 92 determines in step S1 that the automatic copy mode has not been set, it ends the process, and if it determines that the automatic copy mode has been set, the process proceeds to step S2.
[0110]
In step S2, the optical disk data reading unit 92 reads an index file (for example, a file named “INDEX.XML” in FIG. 6) recorded on the optical disk 2. As described above, in the index file read here, information for managing data recorded on the optical disc 2 is described. The index file is output to the control unit 93, and its description is interpreted by the XML interpreting unit 112.
[0111]
Here, the configuration table data file and the edit list file (for example, files under the “EDTR” directory in FIG. 6) in FIG. 6 are read out as appropriate, and the optical disk 2 is read based on the information described in those files. May be determined. For example, in a case where simple editing has already been performed on another device and the IN point and the OUT point are described in the edit list, only the proxy data in the range specified by the list is read out by a read process (for example, It is read by step S8).
[0112]
In step S3, the HDD data reading unit 95 reads an index file which is information for managing data recorded on the HDD 46. For example, similarly to the optical disk 2, the HDD 46 also stores an index file for managing the recorded proxy file and the file name and update date and time of the metadata. The index file read by the HDD data reading unit 95 is output to the control unit 93.
[0113]
In step S4, the determination unit 111 of the control unit 93 refers to the interpretation result of the index file read from the optical disc 2 by the XML interpretation unit 112, and sets “1” to a variable N representing a clip to be determined. I do.
[0114]
Also, in step S5, the determination unit 111 refers to the index file and determines the proxy file of the N-th clip (first in the case of a process performed after step S4) recorded on the optical disc 2, Get the file name and update date and time.
[0115]
For example, as shown in FIG. 6, when folders “C0001” to “C0003” are stored in the clip directory, the clip with the name “C0001” is set as the first determination target clip. It is said. Then, “C0001S01.MXF”, which is the file name of the file storing the proxy data in FIG. 7 and stored in the “C0001” directory, and the update date and time (time stamp) added thereto are obtained from the index file. Is done.
[0116]
In step S6, the determination unit 111 determines whether or not the proxy file having the file name and the update date and time read in step S5 is already recorded in the HDD 46 based on the index file read from the HDD 46 in step S3. Judgment. That is, in the index file read from the HDD 46, the file name and the update date and time of the proxy file already recorded in the HDD 46 are described, and the file name and the update date and time read from the optical disc 2 are described therein. It is determined whether or not there is a match.
[0117]
When the determining unit 111 determines that the proxy file having the file name and the update date and time read from the optical disk 2 is recorded in the HDD 46 in step S6, the process proceeds to step S7, and the value of the variable N is incremented by one. Thereafter, the process returns to step S5 to execute the subsequent processing.
[0118]
Therefore, if the variable N is set to “1” and the clip with the name “C0001” is to be determined, then the variable N is set to “2” and the value Is set as the determination target, and the processing after step S5 is performed.
[0119]
On the other hand, in step S6, the determination unit 111 determines that the proxy file having the file name and the update date and time read from the optical disc 2 is not recorded in the HDD 46 or has the same file name, but the update date and time is different. If it is determined that they are different, the process proceeds to step S8, where the optical disk data reading unit 92 is controlled to read the proxy file of the Nth clip and the metadata file (clip metadata file, frame metadata file).
[0120]
Therefore, when “1” is set to the variable N and a clip with the name “C0001” is set as a determination target, “C0001S01.MXF” in FIG. 7 that is a proxy file of the clip is used. , A file with the name “C0001M01.XML”, which is a clip metadata file, and a file with the name “C0001R01.BIM”, which is a frame metadata file.
[0121]
The read proxy file and metadata file are output to the writing unit 96 via the control unit 93, and are written (recorded) in the HDD 46 by the writing unit 96 in step S9. At this time, the index file that manages the data recorded in the HDD 46 is also updated, and information such as the file names of the newly written proxy file and metadata file and the update date and time is registered in the index file. The proxy video data in the proxy file recorded on the HDD 46 is also output to the representative image generation unit 97.
[0122]
As a result, the proxy file and the metadata file not recorded in the HDD 46 or the newly updated proxy file and the metadata file are recorded in the HDD 46 without the user himself specifying the file.
[0123]
In step S10, the interpretation unit 112 of the control unit 93 controls the HDD data reading unit 95 to read the clip metadata file among the metadata files recorded on the HDD 46 and interpret the clip metadata described therein. Then, an essence mark and a still image list are obtained. As described above, the clip metadata file described in the XML-based language includes an essence mark indicating a feature of a frame set at the time of shooting or a predetermined frame by simple editing thereafter, for example, A still image list for designating the first frame of the clip as a representative image is included.
[0124]
In step S <b> 11, the interpretation unit 112 outputs the metadata file converted into a file format that can be processed by another device, which is the interpretation result, to the writing unit 96 and causes the HDD 46 to record the metadata file.
[0125]
As described above, when the optical disk 2 is mounted on the optical disk apparatus 1, for a file described in a language such as an XML base, which needs to be interpreted before performing processing, the description is interpreted. Since the result is recorded in the HDD 46, it is not necessary to interpret the metadata when actually starting the editing. That is, the metadata is interpreted when the start of the editing is instructed, and the user needs to interpret the metadata by the optical disc device 1 as compared with the case where the editing using the metadata is performed after the editing is completed. Editing can be started quickly by the amount of time.
[0126]
The information on the essence mark and the still image list interpreted by the interpreting unit 112 is supplied to the representative image generating unit 97.
[0127]
In step S12, the representative image generation unit 97, based on the essence mark and the still image list information supplied from the interpretation unit 112, transmits the proxy video data (a plurality of GOPs (Group Of Pictures) supplied from the control unit 93). ), The GOP including the first frame of the clip and the GOP including the frame in which the essence mark is set are decoded. That is, the representative image generation unit 97 includes, for example, the first frame of the clip or the frame to which the essence mark is set from the proxy video data encoded by the MPEG2 method so that the frame can be stored as a still image. Decode the GOP.
[0128]
Also, in step S13, the representative image generation unit 97 obtains, from the data obtained by decoding in step S12, only the data of the first frame of the clip or the data of only the frame in which the essence mark is set, and performs JPEG Create a representative image by compressing it. The created representative image data is output to the writing unit 96, and is recorded on the HDD 46 in step S14.
[0129]
As described above, since the representative image is created in advance and stored in the HDD 46, the optical disc apparatus 1 creates the representative image based on the data recorded in the HDD 46 when the start of editing is instructed, and Compared to the case where the list is displayed on the edit screen, the list of representative images can be displayed on the edit screen more quickly than the time required for creating the representative image. That is, the user can quickly start editing on the editing screen on which the list of representative images is displayed.
[0130]
Note that the representative image is not limited to one created by the method described here. For example, the picture type (I (Intra) picture, P (Predictive) picture, B (Bidirectionally predictive) picture) of each frame is described in a predetermined file, and the frame in which the essence mark is set is the I picture. Is specified by the file, the representative image generating unit 97 sets the data of the frame as representative image data without decoding the entire GOP. That is, since an I picture is a picture (frame) to be intra-coded (encoded) without referring to another picture, when a frame whose picture type is an I picture is a representative picture, the entire GOP is decoded. No need.
[0131]
In step S15, the determination unit 111 determines whether the process of recording the proxy file and the metadata file of all the clips recorded on the optical disc 2 in the HDD 46 and the process of creating the representative image of the clip have been completed. If it is determined that the processing has not been completed, the process returns to step S5, and the subsequent processing is repeatedly executed. That is, the target clip is switched, and a process of recording the proxy file and the metadata file of the newly targeted clip in the HDD 46 and a process of creating a representative image are performed.
[0132]
On the other hand, when the determination unit 111 determines in step S15 that the processing has been completed for all the clips recorded on the optical disc 2, the processing ends.
[0133]
The above processing is performed every time the optical disk 2 is mounted. Therefore, even if a plurality of optical discs 2 are used for shooting, the user can automatically mount proxy files, metadata files, and the like used for editing simply by mounting them on the optical disc device 1 sequentially. The data can be loaded into the optical disk device 1.
[0134]
Next, with reference to the flowchart of FIG. 10, the editing process of the optical disc device 1 performed on the proxy file recorded on the HDD 46 by the process described with reference to FIGS. 8 and 9 will be described.
[0135]
When the start of editing is instructed, in step S31, the editing control unit 113 controls the HDD data reading unit 95 to read the data of the representative image from the HDD 46, and based on the acquired data, displays the editing screen. A list of representative images is displayed in a predetermined area. Thus, the user who edits can check the first frame of the clip and the frame to which the essence mark is set, and can grasp the contents of the video of the proxy file recorded in the HDD 46.
[0136]
In addition, the user can start editing more quickly than when a representative image is created after instructing the start of editing and a list of representative images is displayed.
[0137]
In step S32, the edit control unit 113 edits the proxy data based on an instruction from the user. For example, the edit control unit 113 performs processing such as setting an IN point and an OUT point in proxy data, and setting an essence mark in a predetermined frame. In this editing, the interpreted metadata recorded in the HDD 46 together with the proxy data in the above-described processing is used. The editing result by the editing control unit 113 is appropriately reflected in proxy data and metadata recorded in the HDD 46.
[0138]
In step S33, the editing control unit 113 determines whether or not the user has instructed to end the editing. If it is determined that the instruction has not been instructed, the process returns to step S32 and repeats the editing based on the user's instruction. .
[0139]
On the other hand, when it is determined in step S33 that the end of the editing has been instructed, the editing control unit 113 ends the processing.
[0140]
Information (edit information 15 in FIG. 2) representing the edit result created by the above processing is transmitted to, for example, a device that edits the main line data via a network. Thereafter, the main line data is edited based on the information of the editing result.
[0141]
In the above description, when the optical disk 2 is loaded in the state where the automatic copy mode is set, the proxy file and the metadata file are automatically loaded into the optical disk device 1. In such a state, such data may be taken in according to an instruction from the user.
[0142]
Next, with reference to the flowcharts of FIGS. 11 and 12, a description will be given of a process of the optical disc apparatus 1 for copying (recording in the HDD 46) a proxy file, a metadata file, and the like in response to an instruction from a user.
[0143]
In step S41, the optical disk data reading unit 92 determines whether or not the user has instructed to copy the proxy file recorded on the optical disk 2 mounted on the drive 38, and waits until it determines that it has been instructed. I do.
[0144]
For example, the operation unit 41 of the optical disc apparatus 1 is provided with a manual copy start button which is operated when instructing the start of copying, and the optical disc data reading unit 92 operates the copy start button by the user. If it is determined that the start of copying has been instructed, the process proceeds to step S42.
[0145]
The processing after step S42 is the same as the processing after step S2 described with reference to FIGS. That is, predetermined clips are sequentially targeted (step S44), and it is determined whether or not a proxy file of the clip has already been recorded in the HDD 46 (step S46). Also, proxy files and metadata files not recorded in the HDD 46, and representative images created based on them are recorded in the HDD 46 (steps S49 and S54). If it is determined that the saving to the HDD 46 has been completed, the processing is terminated.
[0146]
As described above, since the copy can be started when the copy start button is operated, the user can easily record a predetermined file to be used for later editing in the HDD 46 of the optical disc device 1 without selecting the copy by himself. Can be done.
[0147]
The editing process described with reference to FIG. 10 is also performed in the optical disk device 1 in which the data used for editing is recorded on the HDD 46 as described above.
[0148]
FIGS. 13A and 13B are diagrams showing a configuration example of a copying system to which the present invention is applied.
[0149]
In FIG. 13A, the optical disk device 1 and the personal computer 201 are connected via a cable 202 (communication path) such as a cross cable, an IEEE 1394 cable, and a USB (Universal Serial Bus) cable.
[0150]
When the optical disk 2 is mounted on the optical disk device 1, the proxy file and clip metadata file recorded on the optical disk 2 are automatically transferred to the personal computer 201, as in the case of the optical disk device 1 alone. In addition, an automatic copy mode, which is a function of loading data into a built-in HDD, is provided.
[0151]
When the optical disc 2 is mounted on the optical disc apparatus 1 connected via the cable 202 in the state where the automatic copy mode is set, the personal computer 201 controls the optical disc apparatus 1 to record the data on the optical disc 2. Read the proxy file or metadata file, obtain the data via the cable 202 according to TCP / IP (Transmission Control Protocol / Internet Protocol), FTP (File Transfer Protocol), etc. To record. The data recorded on the HDD is used in editing performed by the user. Therefore, in this example, the device that the user edits is the personal computer 201, and the editing is not performed by the optical disc device 1.
[0152]
In FIG. 13B, the optical disk device 1 and the personal computer 201 are connected via a network 203 such as a LAN (Local Area Network) which is a communication path.
[0153]
13B, similarly to the case of FIG. 13A, when the optical disk 2 is mounted on the optical disk device 1, the proxy file, the metadata file, and the like recorded on the optical disk 2 are read by the optical disk device 1, and the network 203 Is recorded on the HDD of the personal computer 201 connected via the.
[0154]
As described above, when the optical disk 2 is loaded into the optical disk device 1, the file used for editing is automatically copied to the HDD of the personal computer 201, so that the user does not need to select the file to be copied by himself. Editing can be easily performed using the personal computer 201.
[0155]
Naturally, the optical disc device 1 and the personal computer 201 may be connected by wireless communication of various standards such as IEEE802.11a instead of a wired cable. Further, a plurality of optical disc apparatuses 1 may be connected to one personal computer 201.
[0156]
As in the case of the optical disc apparatus 1 of FIG. 1, in a series of processes of the personal computer 201 for recording the proxy file and the metadata file in the HDD, the interpretation of the files that need to be interpreted at the start of the editing process is performed in advance. The result of the interpretation is recorded in the HDD, and a representative image is created in advance based on the still image list, the essence mark, and the like, and recorded in the HDD.
[0157]
FIG. 14 is a block diagram illustrating a configuration example of the personal computer 201.
[0158]
The CPU 211 controls the entire operation of the personal computer 201 according to a program stored in the ROM 212 or a program loaded from the HDD 218 to the RAM 213. The RAM 213 also stores data and the like necessary for the CPU 211 to execute various processes.
[0159]
The CPU 211, the ROM 212, and the RAM 213 are mutually connected via a bus 214. The input / output interface 215 is also connected to the bus 214.
[0160]
The input / output interface 215 includes an input unit 216 including a keyboard, a mouse, and the like, a display including an LCD (Liquid Crystal Display), an output unit 217 including a speaker, an HDD 218 including a hard disk, and the like. An optical disk device interface 219 as an interface is connected. That is, data read from the optical disk 2 by the optical disk device 1 and transmitted, for example, via the cable 202 in FIG. 13A is received by the optical disk device interface 219, supplied to the HDD 218 via the input / output interface 215, and recorded. Is done.
[0161]
The communication unit 220 is connected to the input / output interface 215. The communication unit 220 performs a communication process via a network, and transmits, for example, information indicating a result of editing the proxy data by the user to a device that performs the main editing.
[0162]
A drive 221 is connected to the input / output interface 215 as necessary, and a magnetic disk 222, an optical disk 223, a magneto-optical disk 224, or a semiconductor memory 225 is appropriately mounted. Is installed in the HDD 218 in accordance with.
[0163]
FIG. 15 is a block diagram showing an example of a functional configuration realized by executing a control program by the CPU 211 of FIG.
[0164]
The recording control unit 241 realized in the personal computer 201 is the same as the recording control unit 81 shown in FIG. 5 except that a communication control unit 251 is provided. That is, the detecting unit 252, the optical disk data reading unit 253, the control unit 254, the mode setting unit 255, the HDD data reading unit 256, the writing unit 257, and the representative image generating unit 258 in FIG. The reading unit 92, the control unit 93, the mode setting unit 94, the HDD data reading unit 95, the writing unit 96, and the representative image generation unit 97 correspond to each other. In FIG. 15, a detailed description of the configuration corresponding to the configuration in FIG. 5 is omitted as appropriate.
[0165]
The communication control unit 251 controls the optical disk device interface 219 to control communication with the optical disk device 1. The detection unit 252 detects, via the communication control unit 251, that the optical disk 2 is mounted on the drive 38 of the optical disk device 1, and outputs information indicating that the optical disk 2 is mounted to the optical disk data reading unit 253.
[0166]
The optical disk data readout unit 253 has the automatic copy mode set by the mode setting unit 255 similarly to the optical disk data readout unit 92 in FIG. 5, and detects that the optical disk 2 is mounted on the drive 38 of the optical disk device 1. When detected by 252, the proxy file, the metadata file, and the like recorded on the optical disk 2 are read out by the optical disk device 1 via the communication control unit 251 to acquire the data. The proxy file and the metadata file acquired by the optical disk data reading unit 253 are supplied to the writing unit 257 via the control unit 254, and written to the HDD 218 as data used for editing.
[0167]
Next, for example, the processing of the personal computer 201 in the copying system of FIG. 13A will be described. Similar processing is also performed by the personal computer 201 in the copying system of FIG. 13B.
[0168]
First, the processing of the personal computer 201 for copying data recorded on the optical disc 2 will be described with reference to the flowcharts of FIGS. This process is basically the same as the process of the optical disc device 1 described with reference to FIGS. 8 and 9, and a duplicate description will be omitted as appropriate.
[0169]
If it is determined in step S71 that the automatic copy mode is set, the optical disk data reading unit 253 proceeds to step S72, and based on the output from the detection unit 252, the optical disk device connected via the cable 202. It is determined whether the optical disk 2 is mounted on the first drive 38.
[0170]
The optical disk data reading unit 253 proceeds to step S73 when the detection unit 252 detects that the photographed optical disk 2 is mounted on the drive 38 of the optical disk device 1 in step S72, and the optical disk 2 is recorded on the optical disk 2. Read the index file and get it.
[0171]
That is, at this time, a predetermined read command is transmitted from the communication control unit 251 to the optical disk device 1 based on the instruction of the optical disk data read unit 253. In response to receiving the command, the data of the index file read by the optical disk device 1 is output from the computer interface 45 (FIG. 4) of the optical disk device 1 to the cable 202, and the optical disk device of the personal computer 201 Received at interface 219. The index file data received by the optical disk device interface 219 is output to the control unit 254.
[0172]
In step S74, the HDD data reading unit 256 reads an index file that manages data recorded in the HDD 218, and outputs it to the control unit 254.
[0173]
In step S75, the determination unit 271 of the control unit 254 refers to the information described in the index file supplied from the optical disc device 1, and sets “1” to a variable N representing the number of a clip to be determined. Then, the process proceeds to step S76, and the file name and the update date and time of the proxy file of the N-th clip (first in the case of processing performed after step S75) recorded on the optical disk 2 are acquired.
[0174]
In step S77, the determination unit 271 determines whether the proxy file having the file name and the update date and time acquired in step S76 is already recorded in the HDD 218 based on the index file read from the HDD 218, If it is determined that the information has not been recorded, the process proceeds to step S79.
[0175]
In step S79, the determination unit 271 controls the optical disk data reading unit 92 to cause the optical disk device 1 to read the proxy file of the N-th clip and the metadata file that is the incidental information of the clip, and read the proxy file. Fetch proxy file and metadata file. Also in this case, a predetermined read command is transmitted from the communication control unit 251 to the optical disk device 1 via the cable 202, and a proxy file and a metadata file are transmitted from the optical disk device 1 according to the command. .
[0176]
The proxy file and the metadata file obtained from the optical disk device 1 via the cable 202 are output to the writing unit 257 via the control unit 254, and are recorded on the HDD 218 by the writing unit 257 in step S80. At this time, the description of the index file recorded in the HDD 218 is also updated, and the information such as the file name and the update date and time of the written proxy file and metadata file is stored in the index for managing the data recorded in the HDD 218. Registered in the file.
[0177]
As a result, the proxy file and the metadata file read by the optical disk device 1 and supplied via the cable 202 are automatically stored in the HDD 218 of the personal computer 201 without the user performing any operation such as specifying the file. Is recorded.
[0178]
At this time, the proxy video data is supplied from the control unit 254 to the representative image generation unit 258.
[0179]
In step S81, the interpretation unit 272 of the control unit 254 interprets the clip metadata (for example, the file whose name is “C0001M01.XML” in FIG. 7) among the metadata recorded in the HDD 218, and A still image list is acquired, and the process proceeds to step S82, where an interpretation result including information such as an essence mark and a still image list is output to the writing unit 257, and is recorded on the HDD 218.
[0180]
The information of the essence mark and the still image list interpreted by the interpreting unit 272 are also output to the representative image generating unit 258. In step S83, the representative image generating unit 258 outputs the essence mark supplied from the interpreting unit 273. The GOP of the proxy video data including the head frame of the clip and the GOP of the proxy video data including the frame in which the essence mark is set are decoded based on the information of the still image list.
[0181]
In step S84, the representative image generation unit 97 obtains the data of the first frame of the clip or the data of the frame in which the essence mark is set from the data obtained by decoding in step S83, and Is generated, and the process advances to step S85 to cause the HDD 218 to record it.
[0182]
As described above, similar to the case of the above-described optical disk device 1 alone, since the representative image is created in advance and stored in the HDD 218, the representative image is created based on the data recorded in the HDD 218 when the start of editing is instructed. Is created and the user promptly starts editing on the editing screen in which the list of representative images is displayed, compared to the case where the list is displayed on the editing screen. be able to.
[0183]
In step S86, the determination unit 271 determines whether or not the processing of recording the proxy file and the metadata file of all the clips recorded on the optical disc 2 in the HDD 218 and the processing of creating a representative image of the clip have been completed. Is determined, and if it is determined that the processing has been completed, the processing is terminated.
[0184]
The above processing is performed each time the optical disk 2 is mounted on the optical disk device 1 and detected by the detection unit 252 of the personal computer 201. The proxy file and the metadata file used for editing are transmitted to the cable 202. Automatically recorded on the personal computer 201 connected via the PC.
[0185]
Next, with reference to the flowcharts of FIGS. 18 and 19, for example, the personal computer 201 that copies data recorded on the optical disc 2 mounted on the optical disc device 1 of FIG. The processing will be described. This processing corresponds to the processing of the optical disk device 1 described with reference to FIGS.
[0186]
That is, in step S101, the optical disk data reading unit 253 determines whether or not the optical disk 2 is mounted on the drive 38 of the optical disk device 1 based on the output from the detection unit 252. Proceeding to S102, next, it is determined whether or not the user has instructed to copy a proxy file or the like recorded on the optical disk 2.
[0187]
For example, if it is determined that a predetermined copy start button has been operated and that the user has instructed to copy a proxy file or the like, the optical disk data reading unit 253 proceeds to step S103.
[0188]
The processing after step S103 is the same as the processing after step S73 described with reference to FIGS. That is, it is determined whether or not the proxy file of the target clip is recorded on the HDD 218 (step S107). If it is determined that the proxy file is not recorded, the proxy file or meta file read by the optical disc device 1 is determined. A data file or the like is supplied to the personal computer 201 via the cable 202 and recorded on the HDD 218 (step S110). Also, a representative image created based on the proxy file or the metadata file is recorded in the HDD 218 (step S115), and in step S116, it is determined that the saving of the proxy file and the like to the HDD 218 has been completed for all clips. If so, the process ends.
[0189]
As described above, the copy start button and the like are provided, and the copy is started when the copy start button or the like is operated, so that the user can read the predetermined file read by the optical disc apparatus 1 connected via the cable 202. Can be taken into the HDD 218 of the personal computer 201.
[0190]
The editing process described with reference to FIG. 10 is performed based on the data captured as described above.
[0191]
20 and 21 show another copy process performed by the optical disc device 1.
[0192]
That is, in the above, it is determined whether the automatic copy mode is set (for example, FIGS. 8 and 9) or whether an instruction to copy a proxy file is given (for example, FIGS. 11 and 12). In the above, a case has been described in which copying of a proxy file or the like is performed by the optical disk device 1 and the personal computer 201 only by judging either one of them. In the processing of FIGS. 20 and 21, both judgments are appropriately performed. The same processing is executed by the personal computer 201 as well.
[0193]
This process is executed at a predetermined timing when, for example, the power is turned on from off (when the power is turned on) or when the power is turned on (the state where the power is already turned on).
[0194]
In step S131, the detection unit 91 determines whether the optical disk 2 has been mounted or whether the optical disk 2 has already been mounted on the drive 38. If not, the detection unit 91 waits until it determines that the optical disk 2 has been newly mounted. I do.
[0195]
In step S131, for example, the detecting unit 91 determines that the optical disk 2 is newly mounted in the state where the power is turned on, or that the optical disk 2 is already mounted in the drive 38 when the power is turned on. If so, the process proceeds to step S132. Therefore, the user mounts the optical disk 2 in the drive 38 while the power is on, or mounts the optical disk 2 in the drive 38 and turns on the power (switching from off to on). ), And the subsequent processing can be executed.
[0196]
In step S132, the optical disc data reading unit 92 determines whether or not the automatic copy mode is set based on the output from the mode setting unit 94.
[0197]
If the optical disk data reading unit 92 determines in step S132 that the automatic copy mode has not been set, the process proceeds to step S133 to copy the proxy file recorded on the optical disk 2 mounted on the drive 38. It is determined whether or not the instruction has been made by the user, and the process waits until it is determined that the instruction has been made. That is, when the automatic copy mode is not set, even if the optical disk 2 is newly mounted, the copy of the proxy file or the like is not performed until a user's instruction is given.
[0198]
In step S133, for example, when it is determined that the copy start button provided on the operation unit 41 has been operated and an instruction to start copying has been given, the optical disk data reading unit 92 proceeds to step S134.
[0199]
If the optical disk data reading unit 92 determines in step S132 that the automatic copy mode is set, the process proceeds to step S134.
[0200]
The processing after step S134 is the same as the processing after step S2 in FIGS. 8 and 9, for example. That is, predetermined clips are sequentially targeted (step S136), and it is determined whether or not a proxy file of the clip has already been recorded in the HDD 46 (step S138). Also, proxy files and metadata files that are not recorded in the HDD 46, and representative images created based on them are recorded in the HDD 46 (steps S141 and S146). If it is determined that the saving to the HDD 46 has been completed, the processing is terminated.
[0201]
Since the proxy file or the like is imported as described above, when the automatic copy mode is set, the user simply mounts the optical disk 2 on the optical disk device 1 or sets the automatic copy mode. If not set, the proxy file and metadata are automatically loaded into the HDD 46 by simply loading the optical disk 2 into the optical disk device 1 and operating the copy start button without directly specifying the file. be able to.
[0202]
Naturally, the user may directly specify the proxy file (for example, the proxy file of “C0001S01.MXF” in FIG. 7) and record it on the HDD 46. At this time, the metadata corresponding to the proxy file designated by the user is automatically taken into the HDD 46, so that the user can easily start editing using the automatically taken metadata. can do.
[0203]
In the above, the processing of the optical disk device 1 on which the optical disk 2 photographed by the video camera has been mounted and the personal computer 201 connected via the cable 202 has been described. A function (a function of transferring a proxy file, a metadata file, or the like to a device for editing) may be provided in the video camera itself.
[0204]
For example, a proxy file or a metadata file is automatically transferred to a personal computer or the like connected to the video camera via wired or wireless communication at the timing when the shooting with the video camera is completed or in real time during shooting. The user can operate the personal computer to easily and quickly start editing by being transmitted and recorded on the built-in HDD.
[0205]
