Description

  The present invention relates to a content editing system, an editing server device, a content editing method, and a program, and more particularly, to a content editing system, an editing server device, a content editing method, and a program for editing content stored in a server with a client device.

  Digital video content (hereinafter simply referred to as video content) stored on the hard disk of a content server accessible via a public line or network is digitally edited from a personal computer or workstation located at a remote location ( Hereinafter, it is simply referred to as editing.

  For example, a moving image editing system disclosed in Patent Document 1 edits content by remote operation from a terminal device. More specifically, the moving image editing system receives a series of editing instructions from the terminal device, edits the moving image based on the editing instructions, and returns the editing result to the terminal device. The user completes editing while repeating transmission of a new editing instruction based on the editing result and reception of the editing result.

In addition, an editing mode is also conceivable in which content is downloaded to a client via a communication network, the content is edited by the client, and the edited content is uploaded.
JP 2002-369130 A (page 4-6, FIG. 1-3)

In the moving image editing system disclosed in Patent Document 1, it is necessary to transmit the moving image content edited by the server device to the terminal device so that the user can issue a next editing instruction. For this reason, when editing is repeated for the same content, a large amount of data is transmitted from the server device to the client device. In addition, when editing requests are simultaneously received from a large number of users, processing waits in the server device, and it takes time for each user to obtain an editing result.
In the mode of editing on the client device, a large amount of data is transmitted from the client device to the server device. In particular, when a communication network such as an ADSL (Asymmetric Digital Subscriber Line) line is used as the communication network, the communication speed of the uplink is slower than the communication speed of the downlink, the edited content is transferred from the client device to the server device. It took a lot of time to transfer.

  Also, when the playback time of moving image content is long, the moving image content is high quality, or the communication speed from the server device to the client is slow, the transfer time of the content from the server device to the client becomes long. For this reason, there has been a problem that the editor waits for a long time after issuing an editing request for moving image content until the editing can be started.

  These problems are not limited to the type of content to be edited.

  The present invention has been made in view of the above problems, and provides a content editing system, an editing server device, a content editing method, and a program with a small amount of data transmitted and received between the editing server device and the client device. Objective.

  Embodiments according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a content editing system 1 according to an embodiment of the present invention includes an editing server 100 and clients 200A, 200B,..., 200N connected to the editing server 100 via a communication network C. Prepare. Hereinafter, the client 200 will be referred to when the clients are not distinguished. In FIG. 1, three clients are shown, but any number of clients may be used.

  The communication network C is, for example, a public ADSL (Asymmetric Digital Subscriber Line) communication network based on a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol).

  The editing server 100 receives a content editing request from the client 200, and requests the requesting client 200 to reduce the amount of data from the requested content data (hereinafter simply referred to as “content”) without any problem in editing. Send. Then, the editing content data indicating the instruction of the editing operation performed on the content is received from the client 200, and the same editing operation is performed on the content stored in the editing server 100.

  The configuration of the editing server 100 is shown in FIG. As illustrated, the editing server 100 includes a control unit 110, a storage unit 120, an input control unit 130, an output control unit 140, and a communication control unit 150.

  The controller 110 includes, for example, a central processing unit (CPU) and a storage device (RAM (Random Access Memory)) serving as a work area. Based on the operation program stored in the storage unit 120, the control unit 110 executes server-side editing processing and the like while controlling each unit.

  The storage unit 120 is configured by a storage device such as a hard disk device, and stores various operation programs executed by the control unit 110, contents to be edited by the content editing system 1, and the like. As illustrated in FIG. 3, the storage unit 120 includes a content storage unit 121, a client information storage unit 122, and a program storage unit 123.

  As shown in FIG. 4, the content storage unit 121 stores a plurality of versions (reduced version 1, reduced version 2,...) In which the bit rate of the content to be edited is changed. Here, the content edited by the content editing system 1 according to the embodiment of the present invention is moving image data in the MPEG (Motion Picture Experts Group) -4 format (ISO / IEC 14496-2). Also, the bit rate refers to the amount of data necessary for reproducing content for 1 second. For example, using the bit rate of the content for distribution as a basic version, several types of reduced versions with reduced display resolution (number of pixels, number of colors), encoding efficiency, frame rate, etc. are prepared.

  Returning to FIG. 3, the client information storage unit 122 stores client information indicating the operating environment of the client 200 connected to the content editing system 1. As shown in FIG. 5, the client information is stored in the form of a table and includes “client identifier”, “communication speed information”, “processing capability information”, and the like.

  Here, the “client identifier” is identification information that identifies the clients 200A, 200B,. “Communication speed information” includes information indicating the communication speed from the editing server 100 to each client 200. “Processing capacity information” is information indicating the processing capacity of each client 200. For example, the number of CPU clocks provided in the client 200, the screen resolution of the output device connected to the client 200, and the storage capacity of the client RAM. The storage capacity of the auxiliary storage device, information indicating the type of graphic card, and the like are stored.

  Returning to FIG. 3, the program storage unit 123 stores an operation program of the control unit 110. In the operation program, in addition to an arbitrary OS (Operating System: basic software) that controls the basic operation of the editing server 100, a communication program with the client 200 and a server-side editing process described later are realized in cooperation with the OS. Editing server program, etc.

  Returning to FIG. 2, the input control unit 130 is connected to an input device 13 such as a keyboard or a pointing device. The input control unit 130 receives an instruction to the control unit 110 input from the input device 13 and transmits the instruction to the control unit 110.

  For example, an output device 14 such as a display device or a printer is connected to the output control unit 140. The output control unit 140 outputs the processing result of the control unit 110 to the output device 14 as necessary.

  The communication control unit 150 includes a communication device such as a NIC (Network Interface Card) or a router, and controls communication between the editing server 100 and the client 200 via the communication network C.

  Returning to FIG. 1, the clients 200 </ b> A, 200 </ b> B,..., 200 </ b> N receive content from the editing server 100, perform video editing on the received content, and edit the history of editing operations performed during video editing. Send to. The configuration of the client 200 is shown in FIG. Since the configurations of the clients 200A, 200B,..., 200N are the same, the configuration of the client 200A is shown as a representative.

  As illustrated, the client 200 (200A) includes a control unit 210, a storage unit 220, an input control unit 230, an output control unit 240, and a communication control unit 250.

  The control unit 210 includes, for example, a CPU, a storage device serving as a work area, and the like. Based on the operation program stored in the storage unit 220, the control unit 210 executes client-side editing processing, which will be described later, while controlling each unit.

  For example, the storage unit 220 includes a storage device (RAM, hard disk, etc.). The storage unit 220 stores an operation program of the control unit 210 (including an editing client program unique to the present embodiment), editing content, editing history information that records editing operation procedures for the content, and the like.

  Here, the editing client program is a program for performing editing operations for video editing such as scene deletion, replacement, and special effects (for example, superimpose, fade-out, etc.) in units of GOP (Group Of Pictures). is there.

Further, as shown in FIG. 7, the edit history information includes “procedure identifier”, “start time”, “end time”, “edit content specifying information”, and the like.
Here, the “procedure identifier” is identification information that specifies an instruction of an editing operation performed on the content by the editor with the client 200, and is information that specifies the order of the editing operation. The “start time” and “end time” are information that identifies which part of the content the editing operation performed on the content is. In the present embodiment, a time code before the start of content editing is stored. Note that it is also possible to specify the number of frames from the beginning of the picture before the start of editing (the number counted in the basic version). The “editing content specifying information” is information indicating the content of the editing operation performed on the part from the “start time” to the “end time” of the content or the position specified by the “start time” of the content. There are also editing operations that are not associated with “start time” and “end time”, such as editing operations to which the procedure identifier 4 is assigned. Further, in FIG. 7, “edit content specifying information” is described in natural language for easy understanding, but actually, it is described as information of “edit content specifying information” in the control unit 210. In order to facilitate interpretation of the contents, the contents described by using a dedicated description language, markup language, etc., editing instructions of the editing server 100 and the client 200 corresponding to the editing operation, and the like are stored.

  Returning to FIG. 6, for example, an input device 23 such as a keyboard or a pointing device (mouse) is connected to the input control unit 230. The input control unit 230 receives an instruction to the control unit 210 input from the input device 23 and transmits it to the control unit 210.

  For example, an output device 24 such as a display device or a printer is connected to the output control unit 240. The output control unit 240 outputs the processing result of the control unit 210 to the output device 24 as necessary.

  The communication control unit 250 includes a network card, for example, and receives content to be edited by the client 200 from the editing server 100. In addition, the editing history information indicating the content of the editing operation performed on the received content is transmitted to the editing server 100.

  Hereinafter, the editing process will be described with reference to FIGS. FIG. 8 is a flowchart for explaining the editing process. FIG. 9 shows an example of a screen displayed on the output device 24 in the editing process.

  The editor operates the client 200 to issue a content editing request instruction to the editing server 100. Upon receiving the editing request instruction, the client 200 transmits information specifying the content requested to be edited and the editing request to the editing server 100 (step S201).

  Upon receiving the content editing request, the editing server 100 locks the designated content (FIG. 8, step S101). Here, the object to be locked may be all of a plurality of versions of the content or only a specific version (for example, the basic version of FIG. 4).

  Then, the control unit 110 identifies the request source client, searches the client information stored in the client information storage unit 122, and selects a version to be transmitted to the request source client based on the search result. More specifically, communication speed information and processing capability information are extracted from the client information regarding the requesting client, and the content transfer time is less than a threshold (for example, 30 seconds), which is higher than the screen resolution described in the processing capability information. Select one of the plates with a smaller display resolution. The control unit 110 reads the selected version from the content storage unit 121, and transmits the selected version to the client 200 that has requested the content editing via the communication network C (step S102).

  When the content is received (step S202), the control unit 210 operates the editing client program and displays an editing screen as shown in FIG. 9, for example.

  In the editing screen 400 shown in FIG. 9, an area 401 for displaying a picture in the content being edited, an area 402 for indicating the time axis of the content, a portion of the content with a mark, and the like are displayed. There are buttons for inputting an instruction to change a picture (rewinding, fast-forwarding, etc., and a mark or slider arranged in the area 402 also performs this function) and a section to be edited. An area 404 where buttons for inputting editing instructions for content are arranged, an area 405 indicating the current editing position, an end button 406 for the editor to notify the editing client program of the end of editing, etc. Has been.

  The editor operates the input device 23 (for example, a mouse) of the client 200 and clicks a button or the like arranged on the editing screen 400 to input an editing instruction for the content. Then, the control unit 210 receives the input editing instruction (step S203). The control unit 210 identifies the clicked position on the editing screen 400, determines which editing operation is instructed according to the identified position on the screen, and which part of the content is the target of the editing operation. Identify. Then, it is determined whether or not the received editing operation instruction is an editing end instruction (step S204). If the received editing operation instruction is not an editing end instruction (step S204: NO), the control unit 210 generates one-time editing history information based on the instructed editing operation and the content portion, and the storage unit It adds to 220 (step S205). Further, the control unit 210 performs the input editing operation on the content stored in the storage unit 220 (step S206). The edited content is stored in the storage unit 220. Then, the control unit 210 updates the display content such as the area 402 indicating the time axis of the content, the content portion with the mark, and the like according to the updated content. For example, when a part of the content is deleted by the editing operation, the control unit 210 adjusts the display position of the slider and the mark displayed in the area 402 according to the length of the content after the change, and the current The numerical value indicating the editing position of the area 405 indicating the editing position is changed. Then, control unit 210 waits to accept a request for a new editing instruction. The process returns to step S203.

  When the editor repeatedly inputs content range designation and editing operation instructions and then clicks the end button 406 to instruct the end of editing the content (FIG. 8, step S204: YES), the control unit 210 The editing history information stored in the storage unit 220 is transmitted from the communication control unit 250 to the editing server 100 via the communication network C (step S207). Here, when the control unit 210 scans the editing history information from the top and finds an instruction (undo) to cancel the immediately preceding editing operation, the control unit 210 cancels the immediately preceding editing operation and the immediately preceding editing instruction. Is deleted from the editing history information. For example, referring to FIG. 7, the control unit 210 determines that the editing operation to which the procedure identifier 4 is assigned is undo, and determines the editing operation to which the procedure identifiers 3 and 4 are assigned from the editing history information. delete.

  When the editing history information is received from the client 200 (step S107), the control unit 110 of the editing server 100 applies the editing operation included in the received editing history information to each version of the content stored in the content storage unit 121 in the order of instructions. On the other hand, the first editing operation is applied (step S108), and the editing operation performed in the client 200 is traced.

  The control unit 110 stores and updates each edition of the edited content in the content storage unit 121 (step S109). Finally, the control unit 110 releases the lock applied to the content and ends the editing process (step S110).

  As described above, according to the content editing system of the present embodiment, the editing server 100 causes the client 200 to send a version of content whose communication time from a plurality of versions of the content to the requesting client 200 is equal to or less than a threshold value. Select and send. The client 200 performs various editing operations on the received content. The client 200 transmits data representing the editing operation performed on the content to the editing server 100. The editing server 100 edits each version of the content stored in the content storage unit 121 according to the editing operation indicated in the data representing the received editing operation. For this reason, it is possible to reduce the data transfer amount and time from the editing server 100 to the client 200 as compared with the case of sending high-quality content.

  Further, the amount of information transmitted from the client 200 to the editing server 100 is reduced as compared with the case where the content itself as the editing result is returned to the editing server 100. Furthermore, the client 200 collectively transmits editing operations performed by the editor to the editing server 100. For this reason, the editing server 100 collectively executes editing operations for content. For example, when the editing client program supports cancellation (undo) of the immediately preceding editing operation, the editing server 100 does not perform a useless editing operation when tracing the editing operation performed on the client 200 side. I'm sorry.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

  For example, the content editing system 1 according to the present invention can be applied to audio content. In this case, the editing server 100 prepares the sampling rate, the quantization bit, and the coding efficiency changed. Furthermore, the present invention may be applied to contents that simultaneously handle images and / or sounds and texts.

  Moreover, although the said embodiment demonstrated and assumed the scene edited with respect to a single content, it can apply to the edit which combined two or more content. In this case, the client 200 requests content from the editing server 100 as much as necessary for editing. The editing server 100 may store a plurality of contents in the content storage unit 121. In this case, the editing server 100 and the client 200 handle content by distinguishing the content by a file name or the like, for example.

  Further, when receiving an editing request, the editing server 100 determines a bit rate at which the content is to be transmitted based on the communication speed and processing capability of the requesting client 200, and converts the content to the bit rate. You may make it transmit. In this case, since it is not necessary to store different versions of the content in the content storage unit 121 in advance, the types of editable content can be increased.

  Further, every time an instruction for an editing operation is received, data representing the instruction for the editing operation may be transmitted from the client 200 to the editing server 100. Alternatively, data representing an instruction for editing operation may be transmitted during editing. In this case, the control unit 210 is explicitly instructed by the editor to transmit data indicating an instruction for an editing operation, or automatically transmitted at regular intervals. In addition, the control unit 210 clears the editing history information when transmitting data representing an editing operation instruction.

  Further, the client 200 may delete the content stored in the storage unit 220 after the editing is completed (after step S207).

In addition, the editing server 100 may store each version of the content in the content storage unit 121 as each version of another content instead of updating each version in step S109.
In step S109, the editing operation is performed on all of the plurality of versions prepared for the content. However, the editing operation is performed only on a specific version (for example, the basic version in FIG. 4), and the other versions are processed. (Reduced versions 1 to 3 in FIG. 4) may be recreated by bit rate conversion.

  Further, the processes in steps S108 and S109 shown in FIG. 8 need not be performed immediately after the process in step S107. For example, the editing server 100 may edit content by nighttime batch processing. If comprised in this way, the edit server 100 can edit a content when processing is vacant, and it is useful for load distribution.

  Further, the control unit 210 may transmit the data generated for the content editing operation together with data indicating a method for applying the data to the content. In this case, the editing server 100 edits the content stored in the content storage unit 121 based on the received data generated for the editing operation and the data indicating how to apply the data to the content.

  In the above embodiment, the editing server 100 and the client 200 are connected by the communication network C whose downlink communication speed is faster than the uplink communication speed. However, the configuration of the communication network C is limited to this. Absent.

  Note that the content editing system 1 in each of the above embodiments can be realized using a normal computer system, not a dedicated system. For example, a program for executing the above operation is stored in a computer-readable recording medium (FD, CD-ROM, DVD, etc.) and distributed, and the program is installed in the computer to execute the above processing. The editing server 100 and the clients 200A, 200B,..., 200N may be configured. Alternatively, it may be stored in a disk device of a server device on a network such as the Internet and downloaded to a computer, for example.

  Further, when the above-described function is realized by sharing between the OS and the application or by cooperation between the OS and the application, only the part other than the OS may be stored in the medium.

  It is also possible to superimpose a program on a carrier wave and distribute it via a communication network. For example, the program may be posted on a bulletin board (BBS, Bulletin Board System) on a communication network and distributed through the network. Then, the above-described processing may be executed by starting this program and executing it under the control of the OS in the same manner as other application programs.
