Description

  The present invention relates to a media management method and a storage apparatus that are applied to store removable media such as optical disks and configure an archive system in a broadcasting station.

  Conventionally, a cart machine using a video tape cassette has been used to store a large amount of broadcast video and audio information (hereinafter referred to as material as appropriate). However, when storing digitized material and producing a program, a medium that can be randomly accessed is desirable. As a result, media such as an optical disk, a hard disk, and a semiconductor memory are used instead of the tape cassette.

As shown in FIG. 15, the conventional storage system has a configuration in which a disk recorder 201 and an editor 202 are connected by a digital interface such as IEEE (Institute of Electrical and Electronics Engineers) 1394. The disk recorder 201 is loaded with the disk 203, records data on the disk 203, and reproduces data from the disk 203.

  The disk 203 has a phase change recording type optical disk in a cartridge and has a shutter. A laser having a wavelength of 405 nm is used, and has a capacity of 23.3 GB in the case of a single-layer optical disk with one recording layer and 50 GB in the case of a two-layer optical disk with two recording layers. Commercial camcorders that use such discs as recording media (a video camera with a built-in recorder and a trade name) have been put into practical use. The disk 203 described above records, for example, a material photographed by a camcorder.

Compressed high-resolution video / audio data is recorded in a predetermined file format on the disk 203 to enable high-speed file transfer. Furthermore, additional information of recorded video such as date, time, various comments, and ProxyAV data (low bit rate video / audio data) that can be used for offline editing are recorded as metadata on the optical disc 203.

  By utilizing the metadata, unified management of video data, simple and high-speed search, efficient operation, and the like are possible. Further, the editor 202 can directly access the data on the disc 203 via the digital video interface. Data recorded on the disk 203 has a file structure shown in FIG. For example, “C001.XML” indicates one file, for example, an XML (eXtensible Markup Language) format file. A file is high-resolution video / audio data corresponding to a scene, a cut, and the like, and is called a clip. A content (program) is a collection of clips.

  The flowchart shown in FIG. 17 shows the process flow of the conventional storage system. The disk recorder 201 detects that the disk 203 has been inserted (step S1). A disk insertion is notified to the upper editor 202 (step S2).

  In step S3, it is determined whether or not there is a request from the editor 202. If it is determined that there is a request, in step S4, the disc 203 is reproduced, data is read from the disc 203, and the reproduced data is transferred to the editor 202 in file units. The file structure as shown in FIG. 16 is displayed on the display unit of the editor 202. When the operator of the editor 202 designates a desired clip, the clip information is transmitted to the recorder 201 and designated by the recorder 201. Play the recorded clip.

  Step S5 determines whether or not there is a transfer request, and a transfer request is generated by specifying a clip. In step S6, the designated clip is transferred, and a series of processing ends.

The editor 202 can edit using ProxyAV data with a small amount of data, and can be configured to use, for example, a personal computer and a disk drive. Therefore, the material acquired by the camcorder can be edited outside of the news gathering site. When editing news material, cut editing is performed in which clips are connected in order. Further, editing information representing the editing result is recorded on the disk 203 as metadata. The disc 203 on which the material is recorded in this way is stored in the archive system of the broadcasting station.

  When related materials are recorded on a plurality of discs (hereinafter appropriately referred to as source discs), cut editing is performed using the plurality of source discs. The editing information includes information for identifying a disc to be used (hereinafter referred to as a disc ID as appropriate) and information indicating a section of AV data to be used (represented by a time code). The same editing information is written for a plurality of source disks. A plurality of source disks are stored in a broadcast station archive system. The host system of the archive system uses a plurality of source disks, performs editing according to the editing information recorded on the source disk, and creates an edited disk (hereinafter referred to as a destination disk as appropriate).

  Conventionally, in a cart machine using a tape cassette, managing a cassette number for identifying each cassette is described in Patent Document 1 below.

JP-A-7-262757

  Furthermore, when registering video materials recorded on a disc in the archive management device, the metadata recorded at the time of shooting on the disc is used for grouping, and the editing device accesses based on the groove as follows. It is described in Patent Document 2.

JP-A-10-333687

  Conventional storage devices that use tape cassettes or disks have only performed passive processing on the host system. For example, in step S2 in the flowchart of FIG. 17, when a disc is inserted, the recorder 201 only notifies the host system of the ID of the inserted disc. Even in the one described in Patent Document 2 that performs grouping, the host system accesses information stored in the archive system, and the archive system performs passive processing on the host system. It was.

  For this reason, since the host system controls the archive system, there has been a problem that the processing speed and the processing efficiency are not sufficiently improved. As described above, when a plurality of source disks in which relevant news material and editing information are recorded are inserted into the archive system, the host system receives the editing information. Editing is performed by the host system controlling a disk drive that reproduces a plurality of source disks and a disk drive that creates a destination disk according to the editing information.

  Accordingly, an object of the present invention is to provide a media management method and a storage apparatus that can solve the above-mentioned conventional problems by performing an editing process according to editing information in the storage apparatus.

In order to solve the above-described problem, the present invention includes a step of loading a recording / playback unit with one or a plurality of source media used for editing and a destination disk on which editing results are recorded;

3. Configuration and Operation of Storage Device As shown in FIG. 1, a storage device (also called a disk cart system or a disk changer) 100 according to an embodiment of the present invention can be opened and closed on one surface of a box-shaped case 101. A door 102 is provided. In the case 101, a predetermined number of, for example, 20 disks can be stored in each storage unit, a disk storage shelf 103, a drive block for recording / reproducing the disk, a transport block for transporting the disk, a power source, a control unit An electric block or the like in which a computer or the like is stored is disposed.

  The storage apparatus 100 handles removable media such as disks, card-like semiconductor memories, and removable hard disks. In one embodiment, a disk is used. The disc has a phase change recording type optical disc in a cartridge and has a shutter, and is suitable for broadcasting business from imaging in a harsh environment to archiving for a long time. A laser with a wavelength of 405 nm is used for writing / reading the disc, and has a capacity of 23.3 GB in the case of a single-layer optical disc and 50 GB in the case of a double-layer optical disc.

  Camcorders (recorders are integrated video cameras and trade names) that use such discs as recording media have been put into practical use. Furthermore, a portable recorder connected to the camcorder with IEEE1394 has been put into practical use. This recorder has been commercialized as a recorder that can cut and edit the material in the disc and has the function of saving the edited result (edit information defining the start position and length) to the disc as an SMI file in the metadata. Yes. The same editing can be performed not only by the recorder but also by a personal computer and a disk drive in which predetermined application software is installed. Further, a bar code label is affixed to the surface of the cartridge of the disc, and the disc can be managed by the disc ID represented by the bar code.

  Compressed high-resolution video / audio data (High Res file) is recorded on the disc. Furthermore, additional information of recorded video such as date, time, various comments, a Proxy file (low resolution file) that can be used for offline editing, and the editing information described above are recorded on the optical disc 203 as metadata.

  For example, news material photographed by a camcorder is recorded on a disc. Often, material shot on the same day, material shot at the same location, material shot for the same incident, etc. are recorded on one or more discs. A cameraman or the like performs cut editing on such a disc with a recorder having an editing function or a personal computer and a disc drive. That is, editing information includes disc identification information (hereinafter referred to as a disc ID as appropriate) for specifying the disc on which the original material is recorded, and address information such as a time code for specifying the section to be pasted in the original material. Included. The editing information recorded on the plurality of discs on which the original material is recorded is the same.

  An outline of the operation of the storage apparatus 100 will be described with reference to FIG. As shown by arrow A in FIG. 2A, the disk storage shelf 103 can be moved in the horizontal direction, and the disk storage shelf 103 is positioned on the door 102 side (front side) and retracted as shown in FIG. 2B. In other words, a state of being located on the back side in the vicinity of the electric block 104 can be taken.

  The transport block 105 can be moved up and down as indicated by an arrow B, and as shown in FIG. 2A, a lower state located in the vicinity of the drive block 106 as a recording / reproducing unit, and as shown in FIG. 2B, The upper state of the disk storage shelf 103 that has been raised and retracted and located on the front side can be taken. As will be described later, a plurality of, for example, three drive blocks 106a, 106b, and 106c are provided as the drive block 106 that performs recording / reproduction with respect to the disc. When it is not necessary to distinguish the three drive blocks, they are simply referred to as drive blocks 106.

  In normal times, when the transport block 105 is stopped without moving up and down, the disk storage shelf 103 includes the back side (front side) of the door 102 as shown in FIG. Located on the operator side). The disk can be exchanged (inserted / removed) with respect to the disk storage shelf 103 by opening and closing the door 102. The transport block 105 is waiting in front of the drive block 106.

  When the disk is transported from the predetermined shelf (specified by the bin number) of the disk storage shelf 103 to the drive block 106 by the instruction from the application software, the disk storage shelf 103 is moved from the operator side position to the rear position shown in FIG. 2B. Moving. The transport block 105 is moved from the position in front of the drive block 106 to the position in front of the disk storage shelf 103 as shown in FIG. 2B. Then, the disk designated from the upper level is taken from the disk storage shelf 103. Next, the transport block 105 is lowered and moved to a position in front of the drive block 106. A disk is inserted from the transport block 105 into the drive block 106.

  In the drive block 106, when the recorded or reproduced disk is transported to the original bin number shelf of the disk storage shelf 103, the disk storage shelf 103 is moved to the rear position. The disk ejected from the drive block 106 is taken in by the transport block 105, and the transport block 105 is raised and moved to a position in front of the disk storage shelf 103 (see FIG. 2B). Then, the disk is inserted from the transport block 105 into the original shelf of the disk storage shelf 103. The transport block 105 is lowered and moved to a position in front of the drive block 106. The disk storage shelf 103 is moved to the operator side.

  As shown in FIG. 3, the electric block 104 includes an application computer 111, a controller (computer) 112, and a hard disk 113. The hard disk 13 stores a database such as disk attribute information and format information stored in the storage device 100.

The application computer 111 is connected to the editor (NLE) 121 and AV (Audio Visual) server 122 of the host system via a LAN (Local Area Network) such as Gigabit Ethernet (registered trademark) 123. The application computer 111 is preinstalled with interface software, and can exchange data with other devices on the network in a file format (for example, MXF format).

  The editor 121 performs editing using the material from the storage apparatus 100. The AV server 122 receives a material from the storage apparatus 100 and generates a material for transmission. Although not shown, a content server, archive (large-capacity storage), etc. may be connected as a higher system in addition to these.

  From the host system, the storage apparatus 100 appears as an ftp server. The host system can grasp the file system of the disk storage device 100.

  The controller 112 controls the movement of the drive unit 114 such as a motor and a solenoid that drives the mechanism (the disk storage shelf 103 and the transport block 105) of the storage apparatus 100 as described above, and also records / records the drive block 106. Control playback operation. Drive blocks 106A, 106B, 106C and a drive unit 114 are connected to the controller 112. Data recorded / reproduced by the drive blocks 106A, 106B, and 106C is transmitted via the LAN 123. For example, the reason why three drive blocks are provided is to support parallel access from a plurality of host devices. Further, cut editing is performed in the storage apparatus 100 as described later using a plurality of drive blocks.

4). Example of File Structure and Editing Information FIG. 4 shows the file structure in one embodiment of the present invention. A disk is specified by the disk ID, and property information MEDIAPRO.XML of the disk is described. FIG. 5 is an example of MEDIAPRO.XML. MEDIAPRO.XML shows the relationship between ProavID, which is the ID of the disc, and umid, which is the ID of the clip.

  E0001E01.SMI is included as editing information. FIG. 6 is an example of E0001E01.SMI. As shown in FIG. 6, a plurality of values specifying each section cut out from the original material and connected in order are described. The multiple values are shown in FIG. 7 and described below.

umid: A unique ID of the target clip name. The clip unit or a part of the section in the clip is the editing unit.
clipBegin: The beginning position of the clip to be clipped. It is represented by a frame count value counted from the beginning of the clip (that is, a time code value).
clipEnd: The end position of the section to be clipped. It is represented by a frame count value counted from the beginning of the clip (that is, a time code value).

5). Process Flow of One Embodiment A process flow of one embodiment of the present invention will be described with reference to FIGS. This operation is performed under the control of the application computer 111 and the controller 112.

  In step S11 in the flowchart of FIG. 8, the door is opened, the disk is inserted into the shelf (bin) of the disk storage shelf, and the door is closed. In step S12, the barcode attached to the cartridge of the inserted disc is read. The bar code represents the disc ID of the disc. The disc ID is recorded as data on the disc in addition to the barcode. In one embodiment of the present invention, the source disk and the destination disk on which the original material is recorded are identified by the disk ID recorded on the disk.

  In step S13, the disk storage shelf and the transport block perform the operations described above, and the inserted disk is transported to the drive block by the transport block and loaded into the drive block. In step S14, the management file and metadata of the disc loaded with the drive block are read.

  In step S15, it is determined whether or not there is a disk management file that is management data used in the storage apparatus. If it is determined that there is a disk management file, the attribute of this disk is determined to be an archive disk recorded in the storage apparatus and managed in the storage apparatus. In step S16, it is registered in the database as an archive disk. In step S17, the disk is returned to the original bin number shelf of the disk storage shelf.

  As described above, the disk storage shelf moves to the rear position, the transport block takes in the disk ejected from the drive block, the transport block rises and moves to the position in front of the disk storage shelf, and the disk is moved from the transport block. The disc is returned to the disc storage shelf. Thereafter, the transport block is lowered and moved to a position in front of the drive block. The disk storage shelf is moved to the operator side.

  If it is determined in step S15 that there is no disk management file, the attribute of the disk is recognized as an autoinjection disk in step S18. The auto-injection disc is a disc recorded on the outside of the storage device, for example, by a camcorder, and has the purpose of automatically importing the recorded information into the storage system.

  In step S19, the presence or absence of an SMI file is determined. As described above, the SMI file is editing information including a clip ID for specifying a section used for editing in a clip of an original material and address information (start position and end position). Such editing information is a result of editing using a portable recorder or a personal computer and a disk drive.

  If it is determined in step S19 that there is no SMI file, the setting file setting is checked in step S20, and processing is performed according to the setting. The setting file is created when the user opens and sets the menu screen in advance. As an example, the following three settings are possible.

  If the first setting has been made, the processing shown in step S21 is performed. That is, by transferring Discs.STS from the storage device to the host system, the host system (server) set to have inserted the autoinjection disk from the outside is notified. This is a notification only process.

  If the second setting has been made, the process of step S22 is performed. In other words, the proxy file of the low resolution file obtained by compressing the High Res file (high resolution file) is transferred to the set higher system (server) by ftp. For example, the editor of the host system that has received the Proxy file performs editing work and creates editing information. The storage apparatus is controlled so that the storage apparatus performs partial reproduction in accordance with the created editing information, and an MXF file of a part necessary for the main editing is acquired by partial reproduction.

  If the third setting has been made, the process of step S23 is performed. That is, the High Res file (MXF file) is transferred to the higher system (server) set by ftp. The third setting is applied to a system that immediately incorporates an MXF file without editing using the Proxy file.

A user displays a menu screen and operates a device such as a mouse to create a setting file for the application computer 111. The setting file defines the above three processes (modes). That is, only the notification process (step S21), Proxy
A file transfer process (step S22) and a High Res file (MXF file) transfer process (step S23) are defined. The setting file defines the operation when the disk is inserted into the storage device and the transfer destination of data in the disk.

  If it is determined in step S19 that there is an SMI file, in step S24, the disc is played, the SMI file is extracted, and editing information is extracted from the SMI file. In the next step S24, editing such as cut editing is performed according to the extracted editing information. As a result of the cut editing, a destination disc on which the editing result is recorded is created. In step S17, the disk is returned to the original bin number shelf of the disk storage shelf.

  The editing process in step S24 is performed in the order shown in FIG. In step S31, a disc (source disc) on which necessary source audio / video data is recorded is inserted into the drive. From the editing information, the disk ID of one or more source disks can be known. Since there are multiple drives, if there are multiple source disks, when the first source disk is inserted into one of the drives, another source disk is inserted into another drive. And all source disks are inserted into the drive.

  In step S32, one necessary destination disk is inserted into the drive. The destination disk may be newly inserted from the outside, or may be previously inserted into one of the storage shelves.

  In step S33, part or all of the AV (video / audio) data of the source disk is sequentially copied to the destination disk in accordance with the editing information. That is, cut editing is performed. In step S34, it is determined whether there is unprocessed editing information. If there is no unprocessed editing information, the process ends. If it is determined that there is unprocessed editing information, the process returns to step S31. Then, after step S31, the same process as described above is repeated.

6). Specific Example of Editing Process In order to facilitate understanding of the embodiment of the present invention, an example of the editing process shown in FIG. 10 will be specifically described. The section recorded on the source disk DISC1, for example, clip CLIP003 is recorded on the destination disk DISC3. Next, the clip CLIP004 recorded on the source disk DISC2 is recorded on the destination disk DISC3. Further, the clip CLIP005 recorded on the source disk DISC1 is recorded on the destination disk DISC3. As a result, CLIP003, CLIP004, and CLIP005 are sequentially recorded on the destination disk DISC3.

  When performing such editing, the operator selects one of the source disks and stores the disk in the disk storage shelf 103. As shown in FIG. 11, the source disk DISC3 is inserted from the disk storage shelf 103 into the drive block 106A. Since the editing information is recorded as metadata on the source disk DISC1, the editing information is extracted, and the editing information is stored in the memory of the controller 112, for example. The state where the source disk DISC1 is loaded in the drive block 106A is continued.

  Next, the operator selects the source disk DISC 2 and inserts it into the disk storage shelf 103. The controller 112 knows that the source disk DISC2 is a disk used for editing based on the editing information. As shown in FIG. 12, the source disk DISC2 is loaded into the drive block 106C under the control of the controller 112, and the loaded state is continued.

  Next, the operator selects the destination disk DISC 3 and inserts it into the disk storage shelf 103. For example, the controller 112 detects that the disk DISC3 is a blank disk, and the DISC3 is loaded into the drive block 106B under the control of the controller 112 as shown in FIG. 13, and the loaded state is continued. Note that a plurality of disks may be stored in advance in a disk storage shelf, and then it may be determined by the control of the controller 112 whether each disk is a disk used for editing. In this case, it is not necessary for the operator to sort the disks.

  Then, as shown in FIG. 14, the controller 112 controls the drive blocks 106A, 106B, and 106C, and as shown in FIG. Cut editing that connects CLIP005 and CLIP005 in sequence is performed, and a destination disk DISC3 is created.

  As described above, since the editing process is performed in the storage apparatus, the optimum distributed process can be performed. Since the functions are distributed between the host system and the storage device and converted into objects, the entire system is simplified and the quality is improved. Since distributed processing can be optimized locally, processing and response are faster.
