Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanations of already well-known matters and duplicate explanations for substantially the same configuration may be omitted. This is to avoid unnecessary redundancy of the following description and to facilitate the understanding of those skilled in the art.

It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

FIG. 1 is a diagram showing an example of the configuration of the moving image editing system according to the embodiment. As shown in FIG. 1, the moving image editing system includes an editing server 1, a terminal 2, a virtual server 3, and terminals 4a to 4c.

The video editing system is installed in, for example, a television broadcasting station, a video production company, or the like (hereinafter, may be referred to as a broadcasting station or the like). The video editing system generates (edits) a video to be broadcast on television in response to operations of terminals 2, 4a to 4c. The moving image may be referred to as a video or an image.

The editing server 1 is an on-premises server, which is managed and operated by a broadcasting station or the like. The moving image taken by the camera is stored in the editing server 1. Further, the edited moving image is stored in the editing server 1. The unedited video shot by the camera may be referred to as the shooting material. The edited moving image may be referred to as OA (OnAir) material. OA material will be broadcast on television.

The editing file is stored in the editing server 1. The editing file includes information related to video editing, such as information for cutting out a part of the shooting material, character information to be inserted into the shooting material, and audio information to be inserted into the shooting material. In the example of FIG. 1, the editing server 1 stores the editing files P1 and P2.

The edit file is created based on the operations of terminals 2, 4a to 4c. The editing server 1 edits the moving image of the shooting material according to the editing file and generates the OA material to be broadcast on television.

The terminal 2 is an on-premises terminal, and is managed and operated by a broadcasting station or the like. The terminal 2 has a function of editing a moving image stored in the editing server 1. The terminal 2 is connected to the editing server 1 via a broadband network. For example, it is connected to the editing server 1 via a network such as a wired LAN (Local Area Network). By connecting via a broadband network, large-capacity and high-speed communication is realized.

The terminal 2 is installed in an editing room such as a broadcasting station, for example. The terminal 2 has higher specifications and higher cost than the terminals 4a to 4c. For example, the terminal 2 has a higher (more) video editing function than the terminals 4a to 4c, and is connected with a high resolution and a wide communication band, so that the cost is high. Therefore, the number of terminals 2 installed and the number of people who can perform editing work are limited.

The virtual server 3 is an on-premises server, which is managed and operated by a broadcasting station or the like. The virtual server 3 is connected to the editing server 1 via a broadband network such as a wired LAN. Further, the virtual server 3 is connected to the terminals 4a to 4c via a narrow band network such as a wireless LAN. For example, Wi-Fi (registered trademark) connection can be considered. Such a highly convenient narrow band network such as Wi-Fi is a network with a small capacity and low speed communication as compared with a wide band network connecting the terminal 2 and the editing server 1.

The communication band between the virtual server 3 and the terminals 4a to 4c is lower than the communication band between the editing server 1 and the terminal 2. Further, the communication band between the virtual server 3 and the terminals 4a to 4c is lower than the communication band between the editing server 1 and the virtual server 3.

The virtual server 3 operates a virtual client and relays the exchange of information between the terminals 4a to 4c and the editing server 1. In the example of FIG. 1, virtual clients C1 to C5 are operating.

The virtual client running on the virtual server 3 is a screen transfer type virtual client. For example, the virtual client does not download the moving image data of the shooting material and the OA material stored in the editing server 1, but plays them by streaming. The virtual client transmits the screen information streamed and reproduced to the terminals 4a to 4c.

Further, for example, the virtual client receives operation information (input data) from terminals 4a to 4c. The virtual client transmits information according to the received operation information to the editing server 1. For the transfer of screen information and operation information, for example, a protocol such as RDP (Remote Desktop Protocol) or HTTP (Hypertext Transfer Protocol) may be used.

The terminals 4a to 4c are provided with a function of editing the moving image stored in the editing server 1 by the virtual server 3. The video editing function that can be executed on the terminals 4a to 4c is lower (less) than that of the terminal 2, and simple video editing is performed.

The terminals 4a to 4c are used, for example, by employees of a broadcasting station or the like. The terminals 4a to 4c can be moved unlike the terminals 2 installed in the editing room. Employees of broadcasting stations and the like can perform simple video editing using terminals 4a to 4c, for example, in their own seats or conference rooms.

In the following, when each of the terminals 4a to 4c is not distinguished, it is simply referred to as the terminal 4. Further, in the following, the operator of the terminals 2 and 4 may be referred to as a user. The terminal 2 may be referred to as an editing terminal, an on-premise terminal, or an on-premise PC (Personal Computer). The terminal 4 may be referred to as a self-seat terminal, a self-seat PC, or a personal terminal. The communication band may be paraphrased as, for example, a communication speed.

FIG. 2 is a diagram illustrating a schematic operation example of the moving image editing system. In FIG. 2, the same components as those in FIG. 1 are designated by the same reference numerals. The virtual server 3 in FIG. 1 operates five virtual clients C1 to C5, but in FIG. 2, it operates three virtual clients C1 to C3.

As shown by the arrow A1 in FIG. 2, the terminal 4 accesses the virtual server 3.

If there is no free virtual client, the virtual server 3 notifies the terminal 4 that the terminal 4 cannot be accessed, as shown by the arrow A2.

On the other hand, if there is a free virtual client, the virtual server 3 allocates the free virtual client to the accessing terminal 4. For example, the virtual server 3 allocates the virtual client C3 to the terminal 4. As a result, the terminal 4 can indirectly access the editing server 1 via the virtual client C3.

For example, the terminal 4 receives a moving image playback operation from the user. The terminal 4 transmits the operation information of the reproduction operation received from the user to the virtual client C3 as shown by arrows A1 and A3. The virtual client C3 accesses the moving image data of the shooting material and the OA material on the editing server 1 as shown by the arrow A4 based on the operation information of the playback operation. The virtual client C3 streams and reproduces the moving image data of the captured material and the OA material on the accessed editing server 1, and transmits the streamed screen information to the terminal 4 as shown by the arrow A5. The terminal 4 displays a moving image based on the screen information transmitted from the virtual server 3 on the display device.

Further, for example, the terminal 4 receives an editing operation of the editing file on the editing server 1 from the user. The terminal 4 transmits the operation information of the editing operation received from the user to the virtual client C3 as shown by arrows A1 and A3. The virtual client C3 edits the edit file on the edit server 1 as shown by the arrow A4 based on the operation information of the edit operation.

The user can display the screen information of the moving image streamed and reproduced by the virtual server 3 on the display device of the terminal 4 and edit the editing file on the editing server 1. As a result, the user can, for example, cut out a video portion unnecessary for television broadcasting or insert characters into a moving image.

It is difficult for the terminal 4 to instruct a part of the editing contents to the editing file in the editing server 1 due to the specifications, the narrow band network, and the like. That is, the content that can be edited in the terminal 4 is less than the content that can be edited in the terminal 2.

The terminal 2 can directly access the editing server 1 as shown by the arrow A6. For example, the terminal 2 can access, download, and play back the shooting material and the OA material on the editing server 1. Further, the terminal 2 can access the editing file on the editing server 1 and directly edit the editing file. Further, the terminal 2 can instruct the editing server 1 to generate a moving image according to the editing file.

Here, the installation environment of the terminal 2 and the terminal 4 will be described. As described in FIG. 1, the terminal 2 has high specifications and high cost. Therefore, increasing the number of terminals 2 imposes a heavy burden on broadcasting stations and the like. Therefore, in the editing work, since the work requiring high specifications such as the terminal 2 is limited, we focused on utilizing an inexpensive personal terminal 4. However, it is difficult to utilize the terminal 4 outside the editing room of a broadcasting station or the like in terms of compliance because it handles confidential information such as videos related to incidents and accidents. In view of these, the video editing system shown in FIG. 1 can not only introduce a large number of personal terminals 4 at low cost by utilizing the virtual server 3, but also comply with compliance and personal terminals. Since 4, it has become possible to easily edit videos.

For example, the virtual server 3 of FIG. 1 operates a screen transfer type virtual client to stream play a moving image on the editing server 1 and transmit screen information of the played moving image to the terminal 4. As a result, the amount of data communication to the terminal 4 can be suppressed. For example, the communication band of the terminal 4 does not have to be a high band as in the terminal 2, and the cost can be suppressed. The terminal 4 may be a personal computer or the like.

Further, in the moving image editing system of FIG. 1, the communication band (one communication band) between the virtual server 3 and the editing server 1 is set to a wide band, and the communication band between the virtual server 3 and the terminal 4 is set to the virtual server 3. By using Wi-Fi or the like, which has a narrower band than the communication band with the editing server 1, an environment is provided in which a plurality of users can perform editing work using the terminal 4. As a result, the moving image editing system of FIG. 1 can reduce the cost.

Further, the virtual server 3 of FIG. 1 streams and reproduces the moving image on the editing server 1, and transmits the screen information of the reproduced moving image to the terminal 4. Further, the virtual server 3 receives the operation information from the terminal 4 and edits the editing file on the editing server 1. As a result, since the terminal 4 does not directly access the editing server 1 (because it is indirectly accessed via the virtual server 3), it is possible to suppress leakage of the moving image and the editing file to the outside. Moreover, the data of the moving image and the editing file does not remain in the virtual server 3 and the terminal 4. As a result, it is possible to suppress leakage of moving images and edited files to the outside.

FIG. 3 is a diagram showing an example of a block configuration of the editing server 1, the terminal 2, the virtual server 3, and the terminal 4.

The editing server 1 has a communication unit 11, a control unit 12, and a storage unit 13.

The display unit 25 is, for example, a display device such as an LCD (Liquid Crystal Display) and an organic EL (Electro Luminescence). The display unit 25 displays an image based on the signal output from the control unit 22.

The virtual server 3 has a communication unit 31, a control unit 32, and a storage unit 33.

The communication unit 31 communicates with the editing server 1 via a broadband network such as a wired LAN. Further, the communication unit 31 wirelessly communicates with the terminal 4 via a narrow band network such as a wireless LAN.

The control unit 32 controls the entire virtual server 3. The control unit 32 may be configured by a processor such as a CPU, for example. The control unit 32 executes a program stored in the storage unit 33, for example, and exerts a predetermined function.

For example, the control unit 32 operates a virtual client (realizes the function of the virtual client) and assigns the virtual client to the terminal 4 that has requested access. The virtual client realizes a moving image editing function by an OS (Operating System) stored in the storage unit 33 and an application for editing a moving image.

The application that edits the moving image, for example, plays the moving image on the editing server 1 by streaming based on the operation information from the terminal 4. The application for editing the moving image transmits the screen information of the streaming-played moving image to the terminal 4. Further, the application for editing the moving image generates an editing file on the editing server 1 based on the operation information from the terminal 4, and edits the editing file on the editing server 1.

The storage unit 33 stores a program for operating the control unit 32. Further, the storage unit 33 stores data for the control unit 32 to perform calculation processing, data for the control unit 32 to control each unit, and the like.

The control unit 42 controls the entire terminal 4. The control unit 42 may be configured by a processor such as a CPU, for example. The control unit 42 executes a program stored in the storage unit (not shown), for example, and exerts a predetermined function.

The input unit 43 is, for example, an input device such as a keyboard, a mouse, and a touch panel. The input unit 43 receives the user's operation and outputs a signal corresponding to the received operation to the control unit 42.

The display unit 44 is, for example, a display device such as an LCD or an organic EL. The display unit 44 displays an image based on the signal output from the control unit 42.

4A and 4B are sequence diagrams showing an operation example of the moving image editing system. The control unit 42 of the terminal 4 transmits the authentication request information to the virtual server 3 via the communication unit 41 (S1).

The control unit 32 of the virtual server 3 executes the authentication process of the terminal 4 based on the authentication request information transmitted in S1. The control unit 32 of the virtual server 3 transmits the authentication result information of the authentication process to the terminal 4 (S2). If the virtual client in the virtual server 3 is full, the terminal 4 is notified that the terminal 4 cannot be accessed as described by the arrow A2 in FIG.

In the following, it is assumed that the authentication of the terminal 4 is valid. It is assumed that the control unit 32 of the virtual server 3 assigns the virtual client C1 to the terminal 4.

When the virtual client C1 is assigned, a moving image editing screen for editing a moving image is displayed on the display unit 44 of the terminal 4. That is, the virtual client C1 transmits the screen information of the moving image editing screen to the terminal 4. The user of the terminal 4 operates an operation button or the like displayed on the video editing screen of the display unit 44 to select, for example, an editing material (video to be edited).

The control unit 42 of the terminal 4 receives the signal of the editing material selection operation from the input unit 43. The control unit 42 of the terminal 4 transmits the information of the editing material selection operation according to the signal from the input unit 43 to the virtual server 3 via the communication unit 41 (S3).

The editing material information is information for accessing the shooting material and the OA material stored in the storage unit 13 of the editing server 1, and may be, for example, a URL (Uniform Resource Locator).

When the virtual client C1 of the virtual server 3 receives the editing material information transmitted in S5, the virtual client C1 transmits the information of the target material request to the editing server 1 via the communication unit 31 (S6). The information of the target material request is the editing material information (for example, URL) transmitted from the editing server 1 in S5. That is, the virtual client C1 of the virtual server 3 accesses and reads the moving image of the shooting material or the OA material stored in the storage unit 13 of the editing server 1 based on the address information such as the URL.

The control unit 12 of the editing server 1 transmits the buffer data (material buffer data) of the moving image to the virtual server 3 via the communication unit 11 based on the information of the target material request transmitted in S6 (S7). ..

When the control unit 12 of the editing server 1 edits the editing file in S23, the control unit 12 transmits the information of the editing result to the terminal 2 via the communication unit 11 (S28). As a result, the editing result of the moving image is displayed on the display unit 25 of the terminal 2.

The input unit 24 of the terminal 2 receives an edit / save operation from the user, and outputs a signal corresponding to the received edit / save operation to the control unit 22. The control unit 22 of the terminal 2 transmits the information of the edit / save instruction according to the signal from the input unit 24 to the edit server 1 via the communication unit 21 (S29).

The control unit 12 of the editing server 1 saves the editing file being edited based on the information of the editing saving instruction transmitted in S29. The control unit 12 of the editing server 1 transmits the information of the saving result of the editing file to the terminal 2 via the communication unit 11 (S30). As a result, the display unit 25 of the terminal 2 displays that the editing file has been saved in the editing server 1, and the user of the terminal 2 can recognize that the editing file has been saved in the editing server 1.

The input unit 24 of the terminal 2 receives an operation of a moving image generation instruction from the user, and outputs a signal corresponding to the received operation of the moving image generation instruction to the control unit 22. The control unit 22 of the terminal 2 transmits the information of the moving image generation instruction according to the signal from the input unit 24 to the editing server 1 via the communication unit 21 (S31).

The control unit 12 of the editing server 1 generates a moving image based on the information of the editing generation instruction transmitted in S31 (S32). For example, the control unit 12 of the editing server 1 generates an edited moving image (OA material) according to the editing file stored in the storage unit 13. The edited video is a video file that can be viewed as a video without the original video data (shooting material) or the edited file, and is the final video to be aired. The control unit 12 of the editing server 1 stores the generated edited moving image in the storage unit 13. The edit file for generating the moving image is specified at the time of operating the moving image generation instruction.

When the control unit 12 of the editing server 1 generates a moving image according to the editing file, the control unit 12 transmits the information of the generation result to the terminal 2 via the communication unit 11 (S33). As a result, the display unit 25 of the terminal 2 displays that the edited moving image has been generated, and the user of the terminal 2 can recognize that the edited moving image has been generated.

The terminal 2 can download the moving image data of the edited moving image generated by the editing server 1. In addition, the terminal 2 can play back the downloaded edited video. On the other hand, the terminal 4 cannot send an instruction to generate a moving image according to the editing file to the editing server 1. Further, the terminal 4 cannot download the moving image data of the edited moving image generated by the editing server 1. The edited video generated by the editing server 1 may be streamed and played on the virtual server 3, and the screen information of the streamed edited video may be transmitted to the terminal 4.

Further, the terminal 4 may edit the edit file generated and edited by the terminal 2 stored in the edit server 1 via the virtual server 3.

As described above, the video editing system has an editing server 1 that edits a video according to an editing file, a terminal 2 that communicates with the editing server 1 and edits an editing file on the editing server 1, and a screen transfer type virtual client. Has a virtual server 3 that operates and communicates with the editing server 1, and a terminal 4 to which a virtual client is assigned and edits an editing file on the editing server 1. The virtual server 3 of the video editing system streams and reproduces the video on the editing server 1 on the virtual client and the communication unit 31 that wirelessly communicates with the terminal 4 at a communication speed lower than the communication speed between the terminal 2 and the editing server 1. It also has a control unit 32 that transmits screen information of the reproduced moving image to the terminal 4 via the communication unit 31.

As a result, the virtual server 3 wirelessly communicates with the terminal 4 at a communication speed lower than the communication speed between the terminal 2 and the editing server 1, so that the video editing work can be increased at low cost. Further, since the screen transfer type virtual client operates on the virtual server 3 and transmits the screen information of the moving image to the terminal 2, the leakage of the moving image can be suppressed. Further, since the virtual server 3 streams and reproduces the moving image on the editing server 1 on the virtual client and transmits the screen information of the reproduced moving image to the terminal 4, it is possible to suppress the leakage of the moving image.

Further, the communication unit 31 receives the operation information related to the video editing operation received by the terminal 4, and the control unit 32 edits the editing file on the editing server 1 according to the operation information. As a result, the edited file does not remain on the virtual server 3 and the terminal 4, so that the leakage of the moving image and the edited file to the outside can be suppressed.

Further, the control unit 32 provides the terminal 4 with less editing functions than the terminal 2. As a result, the amount of data communication between the virtual server 3 and the terminal 4 can be suppressed, and the virtual server 3 can communicate with a plurality of terminals 4 at low cost.

Further, when the editing file on the editing server 1 to be edited by the terminal 4 is being edited by the terminal 2, the control unit 32 provides the terminal 4 with screen information indicating that the editing file is being edited. It is transmitted to the terminal 4 via the communication unit 31. As a result, it is possible to suppress changes to the edited file that the user does not intend.

Further, the control unit 32 executes the authentication process of the terminal 4 and assigns a virtual client to the terminal 4. As a result, unauthorized access to the editing server 1 of the terminal 4 can be suppressed.

The virtual server 3 may be rented, for example. The rental fee may be determined by, for example, the number of virtual clients running on the virtual server 3.

In this case, the control unit 32 of the virtual server 3 may calculate the usage rates of the plurality of virtual clients. The control unit 32 of the virtual server 3 may calculate an appropriate number of virtual clients to be operated based on the calculated usage rate. Thereby, for example, the rental source of the virtual server 3 can present the optimum number of virtual clients running on the virtual server 3 to the rental destination (broadcasting station or the like).
