[Embodiment]
Next, the basic configuration content of the embodiment of the present invention will be described.

As shown in FIG. 1, a content editing system 1 according to an embodiment of the present invention includes an editing server 100 that holds moving image content (hereinafter referred to as “content”) to be edited, and an editing server via a communication network 300. 100, and a content client 200 (200 </ b> A, 200 </ b> B,..., 200 </ b> N) that performs editing processing of content sent from the editing server 100.
Hereinafter, the client device 200 is referred to when the client device is not particularly distinguished. In FIG. 1, three client devices are shown, but any number of client devices may be used.

  Here, the format to be edited by the content editing system 1 is not particularly limited, but in the present embodiment, moving image data in the MPEG (Motion Picture Experts Group) -4 format (ISO / IEC 14496-2) is taken as an example. I will explain to you.

  Here, as shown in FIG. 2, the moving picture data in the MPEG-4 format classifies data for one screen into an I picture, a P picture, and a B picture by an encoding method.

An I picture is encoded alone. Further, in the P picture, a residual between an image predicted from the immediately preceding I picture or P picture on the time axis and its own image is encoded. Further, in the B picture, a residual between an image predicted from the immediately preceding picture and the immediately following picture on the time axis and itself is encoded.
Here, GOP (Group Of Picture) is defined from the I picture to the picture immediately before the next I picture on the time axis (past side to future side). GOP is a unit of encoding.
The communication network 300 is a public 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 device 200, and transmits compressed data of a scene section used for editing the requested content to the requesting client 200.
Then, an instruction for editing operation performed on the content is received from the client 200, and the editing operation is reflected on the content stored in the editing server 100.

Here, the internal configuration of the editing server 100 will be described.
As illustrated in FIG. 3, the editing server 100 includes a communication control unit (editing data transmission unit) 150 that performs transmission / reception of information related to moving image editing with the client device 200 via the communication network 300, and a storage unit 120. A control unit (editing data generating means) 110 is provided that reads out data of a section designated by an editing request from content stored in advance and generates editing data corresponding to the data.
Further, the control unit 110 edits the corresponding content stored in the storage unit 120 based on the editing instruction information indicating the editing content by the client device 200 with respect to the editing data (stored content editing unit).

  Further, the editing server 100 receives input information input by the operator using the input device 13 and transmits the input content to the control unit 110, and the processing execution content by the control unit 110 is controlled by the program. The output control unit 140 is configured to output to the output device 14 such as a display device.

  The control unit 110 includes, for example, a central processing unit (CPU) and a storage device (RAM: Random Access Memory) serving as a work area, and is executed based on an operation program stored in the storage unit 120. By performing the processing, editing data generation processing and editing processing on the editing server 100 side are realized while controlling each unit.

  The storage unit 120 is composed of 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.

  The operation program stored in the storage unit 120 includes, in addition to an arbitrary OS (Operating System) that controls the basic operation of the editing server 100, an editing process on the editing server 100 side in cooperation with the OS. Includes editing server programs.

  For example, an input device 13 such as a keyboard or a pointing device is connected to the input control unit 130, and an instruction to the control unit 110 input from the input device 13 is received and transmitted 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, and the processing result of the control unit 110 is output 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 with the client device 200 performed via the communication network 300.

  Each of the client devices 200A, 200B,..., 200N receives editing data from the editing server 100, performs non-linear video editing operations on the received data, and edits information indicating the history of editing operations performed. Send to server 100.

  The clients 200A, 200B,..., 200N have the same internal configuration. Therefore, hereinafter, the internal configuration of the client 200A will be described as a representative.

  As shown in FIG. 4, the client apparatus 200 </ b> A includes a communication control unit (edit instruction information transmitting unit) 250 that performs transmission / reception of information related to moving image editing with the editing server 100 via the communication network 300, and the editing server 100. An output control unit (preview display means) 240 for outputting the sent editing data as a preview display to an output device (display device or the like) 14 installed in advance, and an editing operation for the preview display on the output device 14 And a control unit (editing operation means) 210 that records the contents of the editing operation as editing instruction information.

Further, the client device 200A transmits an editing instruction for a preview display input from an editor (a user of the client device 200A) to the control unit 210, and an operation process in the control unit 210 is realized. A storage unit 220 that stores and holds application programs and the like is provided.
The control unit 210 executes the editing operation based on the editing instruction notified from the input control unit 230.

  The control unit 210 includes, for example, a CPU and a storage device that serves as a work area. Based on an operation program stored in the storage unit 220, the control unit 210 controls each unit and performs an editing operation on the client device 200 described later. Perform.

  For example, the storage unit 220 includes a storage device such as a RAM, a hard disk, and an SSD. The recorded editing history information is stored.

  The client device 200 executes an editing client program, which is one of operation programs, to perform video editing such as scene deletion, replacement, and special effects (for example, superimpose, fade-out, etc.) on the content. Various editing operations are performed.

  It should be noted that these various editing operations when the editing client program is executed are performed in GOP units. Thus, for example, editing data can be edited without performing processing such as expansion and recompression on the editing data created in the MPEG-4 format.

As shown in FIG. 5, the edit history information is table information including columns indicating “reproduction order number”, “content identifier”, “start time”, “end time”, and “edit content specifying information”. .
Here, “playback order number” indicates the order in which playback is performed on each moving image, and “content identifier” indicates a unique numerical value (content specifying information) assigned to each moving image content.
The “start time” and “end time” are information for indicating a start point and an end point of a certain range in the moving image content, that is, specifying which part in the moving image content.

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.

In addition, as shown in FIG. 4, for example, an input device 23 such as a keyboard or a pointing device (mouse) is connected to the input control unit 230 of the client device 200.
Further, the input control unit 230 receives an instruction command or the like to the control unit 210 input from the input device 23 and transmits it to the control unit 210.

  For example, it is assumed that 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 or the like that is communicably connected to the communication value network 300, and receives the content edited from the editing server 100 and edited in the client device 200.
In addition, the communication control unit 250 transmits editing history information indicating the content of the editing operation performed by the client device 200 to the received content to the editing server 100.

Here, FIG. 6 shows a data model conceptual diagram of the editing data generated by the editing server 100 and transmitted to the client device 200.
Here, data called Backbone is prepared in order for the client device 200 to perform reproduction, preview reproduction, fast forward, and rewind in a simulated manner locally (FIG. 6).
Each Backbone indicates the corresponding moving image scene in GOP units.

  In addition to the high-quality video data (lane # 0) that is the original image, the video scene data includes preview playback data (lane # 1) and compressed data for fast-forward (compressed data that is downloaded by the client device 200). 2x speed: Lane # 2, 4x speed: Lane # 3, 8x speed: Lane # 4), preview reverse playback data (Lane # 5), compressed data for rewinding (fast rewinding) (2x speed: Lane #) 6, 4 × speed: Lane # 7, 8 × speed: Lane # 8).

  As a result, only a necessary scene section can be transmitted as compressed data to the client apparatus 200, and the client apparatus 200 can perform various preview reproductions using the Backbone data.

Here, FIG. 7 shows the concept of a data model used by the client device 200 during the editing operation.
In FIG. 7, the client apparatus 200 holds preview data (playlist) indicating the Backbone as editing information.
As a result, the editor (the operator of the client device) can proceed with the editing operation while performing preview reproduction at any time.

  A moving image compression rate when handling editing data in units of GOP will be described. For example, when a moving image composed of image data with a resolution of 1920 × 1080 is generated, the transmission speed is about 1000 Mbit / sec.

  On the other hand, when each image data having a resolution of 1920 × 1080 is compressed by JPEG to generate a moving image, the moving image is about 200 Mbit / sec, and a moving image having a resolution of 1920 × 1080 is compressed by MPEG-2. In this case, it is about 10 Mbit / sec.

  Therefore, even if eight data including the preview data (FIG. 6: Lane # 1 to Lane # 8) are generated, the total is 80 Mbit / sec, and the size of the editing data is still smaller than other methods. It can be suppressed small.

  As described above, according to the present embodiment, it is possible to effectively reduce the waiting time during editing processing, the waiting time for editing processing, communication delay, and the like until the editing data is sent from the server device. Therefore, the content in the server device can be edited with a small processing waiting time in the client device.

[Description of Operation of Embodiment]
Next, operation processing contents in the content editing system 1 according to the embodiment will be described.

  First, when a content editing request is received from the client device 200, the editing server 100 reads out content data of a category corresponding to the content of the editing request, and generates editing data corresponding to the content data (editing). Data editing step), this editing data is transmitted to the client apparatus 200 which is the source of the editing request (editing data transmission processing step).

The client device 200 outputs the editing data sent from the editing server 100 as a preview display, and performs an editing operation on the preview display (stored content editing step).
Next, the client device 200 records the contents of the editing operation as editing instruction information, and transmits this editing instruction information to the editing server 100.

  Finally, when the editing server 100 receives editing instruction information indicating editing contents for the content held by the editing server 100, the editing server 100 performs editing on the content based on the editing instruction information.

Here, with respect to the editing data generation step, the editing data transmission processing step, and the stored content editing step, the execution contents may be programmed and executed by the computer of the editing server 100.
In addition, the program may be recorded on a non-transitory storage medium such as a DVD, a CD, or a flash memory. In this case, the program is read from the recording medium by a computer and executed.

[Explanation of editing processing function]
Next, editing processing in the content editing system 1 of the present embodiment will be specifically described based on the flowchart of FIG.

First, a content editing request including content specifying information for specifying content to be edited by the client device 200, a necessary scene section corresponding to each content to be edited, and an editing request message indicating a request for editing the content is sent to the editing server 100. Transmit (step S201).
Here, the content specified by the content specifying information may be one or plural.

  Next, the editing server 100 that has received the content editing request extracts the content specified by the content specifying information and the data of the necessary scene section for each content in GOP units, and generates (pseudo) editing data. (Step S101). Then, the communication control unit 150 transmits the editing data to the client 200 that is the transmission source of the content editing request via the communication network 300 (step S102).

When the client device 200 receives the editing data (step S202), the control unit 210 activates the editing client program and outputs and displays the editing screen on the output device 24.
As a result, the client apparatus 200 is set to the editing input acceptance state.

  Here, the editor operates the input device 23 (for example, a mouse) of the client 200 to input an editing instruction for the content by performing an input operation on a button or the like arranged on the editing screen. The controller 210 receives the input editing instruction (step S203).

  The control unit 210 identifies the clicked position on the editing screen, and identifies which editing operation is instructed or which part of the content is the target of the editing operation according to the identified position on the screen. (Specify editing instructions). 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 (NO: step S204), the control unit 210 displays the editing operation instruction indicating the editing operation content input by the operator and the editing operation target content. The editing history information for one time is generated based on this part, and additionally stored in the storage unit 220 (step S205). Here, the control unit 210 enters a standby state in order to accept a request for a new editing instruction.

The operation processing step returns to the step before step S204, and the editor performs the content editing and content editing operation instruction input repeatedly on the client device 200 as the content editing operation, and then the client device 200 The end of content editing is instructed (FIG. 8, step S204: YES).
Here, the control unit 210 transmits the editing history information stored in the storage unit 220 from the communication control unit 250 to the editing server 100 via the communication network 300 (step S206).

When the communication control unit 150 of the editing server 100 receives the editing history information sent from the client device 200 (step S106), the control unit 110 is stored in the storage unit 120 in the order of instructions included in the received editing history information. Editing operations using the content that is currently in use.
Thus, new content is generated by editing the content, stored in the storage unit 120, and the editing process is terminated (step S107).

As described above, in the content editing system 1 according to the present embodiment, the editing server 100 generates editing data and transmits it to the client device 200, and the client device 200 performs various editing using the received editing data. Perform the operation.
Next, the client 200 transmits data (instruction information) representing the editing operation performed on the content to the editing server 100.

  The editing server 100 uses the content stored in the storage unit 120 as a material, and edits / generates the content according to the editing operation indicated in the data representing the received editing operation.

  For this reason, the amount of information transmitted from the editing server 100 to the client 200 is greatly reduced as compared with the case where all data of the content used for editing is transmitted because the data of only the necessary scene section is compressed and transmitted.

  Further, the amount of information transmitted from the client 200 to the editing server 100 is reduced as compared with the case where the edited content data itself is returned to the editing server 100.

  Thereby, in this embodiment, when the editing server 100 receives a content editing request from the client device 200, the editing server 100 compresses the data of the required scene section of the requested content and transmits it to the requesting client device 200. On the client device 200 side, the editor inputs an editing instruction for the content to the client device 200, and the client device 200 displays a preview of the editing content based on the editing instruction.

  Here, the client apparatus 200 stores the editing instructions in the storage unit, and collectively transmits the editing instructions to the editing server 100 when the editing work is completed. The editing server that has received the editing instruction edits the content by tracing the editing operation performed on the client, so that the editing server 100 can execute an editing operation equivalent to the editing operation performed on the client device 200.

  Further, in this embodiment, the editing operation and preview display are performed locally using the editing data, and the final operation instruction information is sent to the server side to finish the editing operation. Since data transmission to the client device does not occur and processing is not performed on the server device during the editing operation, there is no waiting for processing each time the editing operation is performed. It is possible to effectively reduce the operation waiting time for the client device user to perform.

  In addition, from the server side, only the content data of the scene section used for editing is sent to the client device after compressing the resolution / reproduction bit rate with the inter-frame compressed data, so that the communication amount can be reduced. For this reason, it is possible to effectively reduce or shorten the communication time required for transferring the moving image data used for editing from the server device to the client device.

  Further, since the editing operation is completed by transmitting the editing operation history information from the client device to the server device after the editing operation, it is not necessary to transfer the edited video content itself from the client device to the server device. Thereby, the amount of communication data from the client device to the server device can be effectively suppressed.

About the above-mentioned embodiment, it is as follows when the summary of the novel technical content is put together.
In addition, although one part or all part of the said embodiment is put together as follows as a novel technique, this invention is not necessarily limited to this.
