Description

  The present invention relates to a video data sharing system, a video data sharing program, a video data sharing method, and a video data sharing apparatus.

  At a broadcasting station that handles video data, a media asset management (MAM) system is used to manage video data. The MAM system supports management such as storage and editing of video data in a broadcast station.

  For example, from each of a plurality of terminals connected via a network, information on broadcast date and time for video data as a material of broadcast video of a program is received, and based on the information on broadcast date and time, video data from a plurality of terminals There have been proposals for storage devices that determine the order in which they are received. In this proposal, video data is received from any of a plurality of terminals in accordance with the determined order, so that video data with a short grace period until program broadcasting can be preferentially edited.

  In addition, there is also a proposal of a system that supports collaborative production of media configuration by multiple users. In this proposal, an interactive project synchronization service is considered which synchronizes between the assets of the synchronization media project stored in the client and the assets of the synchronization media project stored in the server.

  Furthermore, there are proposals for systems that provide users with suggestions or templates for editing and generating media assets such as video and audio based on the user's context (such as user input and user profile information).

Hereinafter, the present embodiment will be described with reference to the drawings.
First Embodiment
FIG. 1 is a diagram showing a video data sharing system according to the first embodiment. The video data sharing system 1 includes an information processing device 10 and a video data providing device 20. In addition, the video data sharing system 1 includes a video data receiving device 30. The information processing device 10, the video data providing device 20 and the video data receiving device 30 are connected to the network 2. The information processing device 10 supports sharing of video data of a moving image by the video data providing device 20 and the video data receiving device 30. The information processing apparatus 10 may be called a video data sharing apparatus.

The information processing apparatus 10 includes a storage unit 11 and a control unit 12. The video data providing device 20 includes a storage unit 21 and a control unit 22.
The storage units 11 and 21 may be volatile storage devices such as RAM (Random Access Memory) or non-volatile storage devices such as HDD (Hard Disk Drive) or flash memory. The control units 12 and 22 may include a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), and the like. The control units 12 and 22 may be processors that execute programs. The “processor” may also include a set of multiple processors (multiprocessor). Similarly to the information processing apparatus 10 and the video data providing apparatus 20, the video data receiving apparatus 30 also has a storage unit and a control unit (not shown).

  The storage unit 21 can store, for a specific video theme, first video data of a first resolution and second video data of a second resolution generated based on the first video data. . For example, the first video data may be a video captured by a first user using video data providing device 20 using an imaging device such as a camera or a video created by a first user using a computer (for example, , Animation, etc.). The second resolution of the second video data is, for example, lower than the first resolution of the first video data. The specific theme may be a genre of the first video data and the second video data, a keyword related to the contents of the first video data and the second video data, or the like.

  The control unit 22 controls the video stored in the storage unit 21 in a state in which the first video data is stored in the storage unit 21 but the second video data is not stored in the storage unit 21 for the specific video data. The setting for sharing data to the information processing apparatus 10 is accepted. The control unit 22 transmits the first video data to the information processing apparatus 10 according to the setting, and the second video data according to the addition of the second video data to the storage unit 21. Control to send to.

  For example, the first user can use the input device (not shown) connected to the video data providing device 20 to input the setting for sharing the first video data. The control unit 22 transmits the first video data to the information processing apparatus 10 according to the setting (step Sa1). Thereafter, the control unit 22 performs control to add the second video data to the storage unit 21 (step Sa2). The second video data may be generated by the video data providing device 20 based on the first video data, or may be generated by another computer connected to the video data providing device 20.

  Then, in response to the addition of the second video data to the storage unit 21, the control unit 22 performs control to transmit the second video data to the information processing apparatus 10 (step Sa3). For example, the control unit 22 may automatically transmit the second video data to the information processing apparatus 10 when the second video data is added to the storage unit 21. Alternatively, the control unit 22 sends the second video data to the information processing apparatus 10 when the second video data is added to the storage unit 21 and the input of the transmission instruction by the first user is accepted. It may be sent.

The storage unit 11 stores first video data of a specific video theme received from the video data providing device 20.
The control unit 12 receives first video data of a specific video theme from the video data providing device 20 and performs control to store the first video data in the storage unit 11.

  The control unit 12 transmits the first video data stored in the storage unit 11 to the video data receiving apparatus 30 in response to a request for a specific video theme from the video data receiving apparatus 30, and then the video data providing apparatus When the second video data is received from 20, control to automatically transmit the second video data to the video data receiving device 30 is performed. Here, the video data receiving apparatus 30 is another apparatus different from the information processing apparatus 10 and the video data providing apparatus 20.

  For example, the control unit 12 receives a request for a specific video theme from the video data receiving apparatus 30, and searches the first video data stored in the storage unit 11 corresponding to the specific video theme. Then, the control unit 12 transmits the retrieved first video data to the video data receiving apparatus 30 (step Sb1). At the stage of step Sb1, the second video data has not been completely received by the information processing apparatus 10. When the second video data is received from the video data providing device 20 after step Sb1, the control unit 12 performs control to automatically transmit the second video data to the video data receiving device 30 (step Sb2). The control unit 12 also performs control to store the received second video data in the storage unit 11 for the purpose of sharing video data thereafter.

According to the video data sharing system 1, video data can be shared efficiently. Specifically, it is as follows.
Here, video data held by one broadcast station (or a video production company) may be acquired by another broadcast station and edited for broadcast by another broadcast station. In this case, the video data providing device 20 belongs to a certain broadcast station (or a video production company). The video data receiver 30 belongs to another broadcast station. The video data for editing includes, for example, high-resolution first video data to be edited, and low-resolution second video data used for confirmation of each scene in the first video data. included. When sharing video data between the broadcasting station of the providing source and the broadcasting station of the providing destination, the presence or absence of the video data and the editing status at the providing source / providing destination are confirmed between users who work at the providing source / providing destination. Video data is provided as needed from the provider to the provider at the discretion of the user. However, in this method, it takes time to cooperate between the providing source / providing destination users, and there is a problem that video data can not be shared efficiently.

  Therefore, in the video data sharing system 1, the information processing device 10 holds the first video data of the first resolution of the specific video theme received from the video data providing device 20. The information processing apparatus 10 transmits the first video data in response to the request of the video data receiving apparatus 30, and then receives the second video data of the second resolution of the same theme from the video data providing apparatus 20. The second video data is automatically transmitted to the video data receiving apparatus 30. As a result, it is possible to save labor of cooperative work of providing video data while confirming editing status between a user who uses video data provision device 20 and a user who uses video data reception device 30, and sharing of video data is efficient. Can be In particular, as soon as various video data are created at the broadcasting station or the like that provided the video data, the created video data can be shared in a timely manner (timely).

Hereinafter, the functions of the video data sharing system 1 will be described in more detail by exemplifying a more specific system.

The video providing server 200 is provided in the A broadcast station 70 of a certain broadcaster. The video reception server 300 is provided in the B broadcast station 80 of another broadcaster. However, the B broadcast station 80 may be a local station of the same broadcaster as the A broadcast station 70 and a local station different from the local area where the A broadcast station 70 exists. The provinces may be either domestic or foreign provinces. Further, the types of the A broadcast station 70 and the B broadcast station 80 are also various, and for example, a broadcast station specialized in sports programs and a broadcast station specialized in information provision programs can be considered.

  The management server 100 is a server computer that supports sharing of video data of moving pictures in the A broadcast station 70 and the B broadcast station 80. The management server 100 also performs charge management accompanying sharing of video data. Billing occurs at a broadcast station that has acquired video data from another broadcast station (or a video production company). That is, when a certain broadcast station receives provision of video data from another broadcast station etc., the provided broadcast station may pay compensation to the other broadcast station etc. which is the provision source (eg If you receive paid video data from the broadcaster's broadcaster in

  The management server 100 may be realized by on-premise or by cloud computing. For example, each broadcast station can use video cloud computing services to provide video data with other broadcast stations without preparing hardware such as a server computer or storage having the function of the management server 100 by itself. It is easy to share

  The video providing server 200 is a server computer that stores the video data acquired by the A broadcast station 70.

  Here, each of the video providing server 200 and the video receiving server 300 cooperates with the management server 100 to both provide the video data to another broadcast station and receive the video data of the other broadcast station. Have. In the second embodiment, a case is mainly exemplified where the video providing server 200 plays a role of providing video data, and the video receiving server 300 plays a role of receiving video data. In order to easily distinguish the respective roles, server names are made separate, such as the video providing server 200 and the video receiving server 300. However, the video providing server 200 may obtain the video data provided by the video receiving server 300.

  FIG. 3 is a diagram showing an example of hardware of a management server. The management server 100 includes a processor 101, a RAM 102, an HDD 103, an image signal processing unit 104, an input signal processing unit 105, a medium reader 106, and an NIC (Network Interface Card) 107. Each hardware is connected to the bus of the management server 100. The video providing server 200 and the video receiving server 300 can also be realized using the same hardware as the management server 100.

  The processor 101 is hardware that controls the information processing of the management server 100. The processor 101 may be a multiprocessor. The processor 101 is, for example, a CPU, a DSP, an ASIC, or an FPGA. The processor 101 may be a combination of two or more elements of a CPU, a DSP, an ASIC, an FPGA, and the like.

  The RAM 102 is a main storage device of the management server 100. The RAM 102 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the processor 101. The RAM 102 also stores various data used for processing by the processor 101.

  The HDD 103 is an auxiliary storage device of the management server 100. The HDD 103 magnetically writes data to and reads data from the built-in magnetic disk. The HDD 103 stores an OS program, an application program, and various data. The management server 100 may include other types of auxiliary storage devices such as a flash memory and a solid state drive (SSD), and may include a plurality of auxiliary storage devices.

  The image signal processing unit 104 outputs an image to the display 51 connected to the management server 100 in accordance with an instruction from the processor 101. As the display 51, a CRT (Cathode Ray Tube) display, a liquid crystal display, or the like can be used.

  The input signal processing unit 105 obtains an input signal from the input device 52 connected to the management server 100, and outputs the input signal to the processor 101. As the input device 52, for example, a pointing device such as a mouse or a touch panel, a keyboard, or the like can be used.

  The medium reader 106 is a device that reads a program or data recorded on the recording medium 53. As the recording medium 53, for example, a magnetic disk such as a flexible disk (FD: Flexible Disk) or HDD, an optical disk such as a CD (Compact Disc) or a DVD (Digital Versatile Disc), a magneto-optical disk (MO: Magneto-Optical disk) It can be used. Further, as the recording medium 53, for example, a non-volatile semiconductor memory such as a flash memory card can be used. The medium reader 106 stores programs and data read from the recording medium 53 in the RAM 102 or the HDD 103, for example, in accordance with an instruction from the processor 101.

  The NIC 107 is a communication interface that communicates with the management server 100 via the network 50. The NIC 107 may be a wired communication interface or a wireless communication interface.

  FIG. 4 is a diagram showing an example of the function of the video data sharing system. The management server 100 includes a storage unit 110, a reception processing unit 120, a conversion unit 130, and a transmission processing unit 140. The storage unit 110 is realized by the storage area of the RAM 102 or the HDD 103.

  The reception processing unit 120, the conversion unit 130, and the transmission processing unit 140 are realized by the processor 101. For example, the processor 101 executes the program stored in the RAM 102 to exert the functions of the reception processing unit 120, the conversion unit 130, and the transmission processing unit 140. Alternatively, the reception processing unit 120, the conversion unit 130, and the transmission processing unit 140 may be realized by hardwired logic such as FPGA or ASIC.

The storage unit 110 stores video data and metadata 111 related to the video data.
The metadata 111 is information indicating a video theme of video data, and is, for example, a genre of video data, a keyword representing contents, or the like.

The high resolution material 112 is high resolution among video data provided by the video providing server 200. "High resolution" is an abbreviation of high resolution (Resolution).
The low resolution material 113 has a lower resolution than the high resolution material 112 among the image data provided by the image providing server 200. "Low resolution" is an abbreviation of low resolution. The low resolution material 113 is created from the high resolution material 112 by the image providing server 200.

  The high resolution transmission image 114 is image data after editing, in which the high resolution material 112 is edited by the image providing server 200. The high resolution transmission image 114 is created from the high resolution material 112 by the image providing server 200.

  The code conversion video 115 is video data after transcoding (code conversion) of the transmission high resolution video 114 by the management server 100. Transcoding is processing for converting an encoding format of video data from a first encoding format to a second encoding format. Examples of video data encoding formats include QuickTime (registered trademark) format (extension: ". Mov"), DVC (Distributed Video Coding) format (extension: ". DVC"), and MXF (Material eXchange Format) format. (The extension is ".mxf").

  The reception processing unit 120 receives the metadata 111, the high resolution material 112, the low resolution material 113, and the high resolution video for transmission 114 from the video providing server 200, and stores the metadata 111 in the storage unit 110.

  The conversion unit 130 is a transcoder that converts the encoding format of the transmission high resolution video 114 to generate a code conversion video 115. The conversion unit 130 determines the encoding format of the conversion destination according to the encoding format handled by the request source of the video data, and executes transcoding.

  The transmission processing unit 140 transmits the metadata 111, the high resolution material 112 and the low resolution material 113 received from the video providing server 200 to the video reception server 300 in response to a request from the video reception server 300. Further, the transmission processing unit 140 transmits the high resolution video for transmission 114 or the code conversion video 115 to the video reception server 300 according to the encoding format handled by the software of the video reception server 300.

The video providing server 200 includes a storage unit 210, a transmission processing unit 220, and a reception processing unit 230.
The storage unit 210 is realized by a storage area of a RAM or an HDD provided in the video providing server 200.

  The transmission processing unit 220 and the reception processing unit 230 are realized by a processor included in the video providing server 200. For example, the processor performs the functions of the transmission processing unit 220 and the reception processing unit 230 by executing a program stored in the RAM included in the video providing server 200. Alternatively, the transmission processing unit 220 and the reception processing unit 230 may be realized by hard wired logic such as FPGA or ASIC.

  The storage unit 210 stores the metadata 211, the high resolution material 212, the low resolution material 213, and the high resolution video for transmission 214. The metadata 211 is set for the high resolution material 212 by the user of the A broadcast station 70. The high resolution material 212 is high resolution video data acquired by the A broadcast station 70. The low resolution material 213 is low resolution video data generated based on the high resolution material 212 by the video providing server 200 or another computer connected to the video providing server 200. The transmission high resolution video 214 is video data after editing of the high resolution material 212 by the user of the A broadcast station 70.

  The transmission processing unit 220 sequentially transmits the metadata 211, the high resolution material 212, the low resolution material 213, and the high resolution video for transmission 214 stored in the storage unit 210 to the management server 100. The metadata 111, the high resolution material 112, the low resolution material 113, and the high resolution video for transmission 114 in the management server 100 correspond to the metadata 211, the high resolution material 212, the low resolution material 213, and the high resolution video for transmission 214, respectively. .

When acquiring the video data of the B broadcast station 80, the reception processing unit 230 receives the video data from the management server 100 and stores the video data in the storage unit 210.
The video reception server 300 includes a storage unit 310, a transmission processing unit 320, and a reception processing unit 330.

The storage unit 310 is realized by a storage area of a RAM or an HDD provided in the video reception server 300.
The transmission processing unit 320 and the reception processing unit 330 are realized by a processor included in the video reception server 300. For example, the processor executes the program stored in the RAM included in the video reception server 300 to exert the functions of the transmission processing unit 320 and the reception processing unit 330. Alternatively, the transmission processing unit 320 and the reception processing unit 330 may be realized by hard wired logic such as FPGA or ASIC.

  The storage unit 310 stores the metadata 311, the high resolution material 312, the low resolution material 313, and the high resolution video for transmission 314. The metadata 311 is metadata provided by the video providing server 200. The high resolution material 312 is high resolution video data provided by the video providing server 200. The low resolution material 313 is low resolution video data provided by the video providing server 200. The transmission high resolution video 314 is video data after editing of the high resolution material 312 provided by the video providing server 200. The transmission high resolution video 314 may be the same as the transmission high resolution video 214 (and the transmission high resolution video 114), or may be the same as the code conversion video 115 after transcoding by the management server 100. In some cases.

The transmission processing unit 320 transmits the video data stored in the storage unit 310 to the management server 100 when the video data is provided to the A broadcast station 70.
The reception processing unit 330 receives the metadata 311 provided by the A broadcast station 70, the high resolution material 312, the low resolution material 313, and the high resolution video for transmission 314 from the management server 100, and stores the information in the storage unit 310.

  FIG. 5 is a diagram showing an example of editing video data. In FIG. 5, as an example of the high resolution material 212, the low resolution material 213, and the transmission high resolution image 214 in the image providing server 200, a baseball game image is considered.

  The high resolution material 212 is high resolution video data captured by a camera provided in a baseball stadium. For example, the high res material 212 includes a three-hour video shot from the start of the game to the end of the game. Also, the high resolution material 212 includes three highlight scenes such as home runs. The high resolution material 212 can be edited by another broadcast station (for example, the B broadcast station 80) that has received the provision of the high resolution material 212.

  The low resolution material 213 is created by the image providing server 200 by reducing the resolution of the high resolution material 212. The low resolution material 213, like the high resolution material 212, includes a three-hour video shot from the game start to the game end. By reducing the resolution, the data size of the low resolution material 213 is smaller than the data size of the high resolution material 212. For this reason, software that uses low-res material 213 rather than high-res material 212 for work that extracts one scene in the entire video, such as confirmation of highlight scenes, is used for the work. Processing load is reduced, and work can be performed efficiently (for example, fast).

  The high resolution transmission image 214 is generated based on the high resolution material 212. The high resolution transmission image 214 is, for example, an image obtained by extracting and connecting three highlight scenes in the high resolution material 212 without lowering the resolution of the high resolution material 212. For this reason, the time from the start to the end of the high resolution transmission video 214 is shorter than the time from the start to the end of the high resolution material 212. The transmission high resolution video 214 is edited so as to be a predetermined time (for example, three minutes). If the predetermined time of the high resolution video for transmission 214 matches the length scheduled for the program, the B broadcast station 80 that has received the provision of the high resolution video for transmission 314 corresponding to the high resolution video for transmission 214 transmits It is also possible to broadcast the credit high resolution video 314 to the viewer within the program as it is.

  FIG. 6 is a diagram showing an example of a providing video management table. The providing video management table 215 is stored in the storage unit 210. The provided video management table 215 includes items of title, metadata, high resolution material, low resolution material, transmission high resolution image, status, and shared flag.

  The title of the video data is registered in the item of the title. Metadata is registered in the item of metadata. In the high resolution material item, the identification name (file name) of the high resolution material file is registered. In the item of low resolution material, the file name of low resolution material is registered. When the low resolution material corresponding to the high resolution material is not yet present, the item of the low resolution material is not set (represented by a “-” hyphen symbol). The file name of the transmission high resolution video is registered in the item of the transmission high resolution video. If there is no transmission high resolution video corresponding to the high resolution material, the transmission high resolution video item is not set. In the item of status, a status indicating the editing status of the video data in the video providing server 200 is registered. The status includes, for example, "not created", "editing" and "edited". "Not created" indicates that creation of a high resolution transmission image has not been started. "Editing" indicates that a high resolution transmission image is being created. "Edited" indicates that a high resolution transmission image has been created. In the item of the share flag, a share flag indicating whether to permit sharing of the video data with another broadcast station is registered. The sharing flag "TRUE" indicates that sharing is permitted. The sharing flag "FALSE" indicates that sharing is not permitted. The initial value of the sharing flag is "FALSE".

  For example, in the video management table for provision 215, the title is "Team G vs. Team T", the metadata is "Nagashima", the high res material is "nagasima S. mov", the low res material is "nagasima L. mov", for transmission Information is registered that the high resolution video is "nagasima H. mov", the status is "edited", and the sharing flag is "TRUE".

  This indicates that metadata "Nagashima" is attached to the video data titled "Team G vs. Team T". In addition, the high resolution material of the file name "nagasimaS. Mov", the low resolution material of the file name "nagasima L. mov", and the high resolution image for transmission of the file name "nagasima H. mov" correspond to the combination of the title and metadata. Indicates to do.

Next, the processing procedure of the video data sharing system will be described. First, the processing procedure of the video providing server 200 will be described.
FIG. 9 is a flowchart showing an example of processing of the video providing server. Hereinafter, the process shown in FIG. 9 will be described in order of step number.

  (S11) The transmission processing unit 220 transmits the title of the high resolution material 212 stored in the storage unit 210, the metadata 211, and the editing status of the high resolution material 212 to the management server 100. The video data to which the editing status is transmitted is limited to video data for which the sharing flag “TRUE” is set in the providing video management table 215 stored in the storage unit 210. At this timing, the transmission processing unit 220 is in a state where the high resolution material 212 is stored in the storage unit 210 but the low resolution material 213 is not stored in the storage unit 210 for the specific metadata 211. In this state, the transmission processing unit 220 includes the management server 100 with video data such as the high resolution material 212 stored in the storage unit 210 and the low resolution material 213 derived from the high resolution material 212 and the high resolution video for transmission 214. It is possible to receive a setting (sharing flag “TRUE”) shared with another server.

  In addition, when the high resolution material 212 is stored in the storage unit 210 and the sharing flag is set to “TRUE”, the transmission processing unit 220 transmits the status “not created” as the editing status to the management server 100. The transmission processing unit 220 transmits the status “editing” to the management server 100 when the editing of the high resolution material 212 is started. The transmission processing unit 220 transmits the status “edited” to the management server 100 when the editing of the high resolution material 212 is completed and the creation of the high resolution video for transmission 214 is completed.

(S12) The reception processing unit 230 receives a request for the high resolution material 212 from the management server 100.
(S13) The reception processing unit 230 transmits the high resolution material 212 stored in the storage unit 210 to the management server 100.

(S14) The predetermined video processing software in the video providing server 200 generates the low resolution material 213 from the high resolution material 212, and stores the low resolution material 213 in the storage unit 210.
(S15) When the low resolution material 213 is stored in the storage unit 210, the transmission processing unit 220 transmits the low resolution material 213 to the management server 100.

  (S16) The predetermined video processing software in the video providing server 200 receives the editing operation of the user of the A broadcast station 70 with respect to the high resolution material 212, and generates the high resolution video for transmission 214 according to the editing. Store in

(S17) When the transmission high resolution video 214 is stored in the storage unit 210, the transmission processing unit 220 transmits the transmission high resolution video 214 to the management server 100.
(S18) The transmission processing unit 220 settles the video provision charge according to the provision of the transmission high resolution video 214. The transmission processing unit 220 transmits the video provision fee to the management server 100. Then, the transmission processing unit 220 ends the process.

  As described above, the video providing server 200 detects the high resolution material 212 and the high resolution material 212 in a state where the high resolution material 212 is stored in the storage unit 210 but the low resolution material 213 is not stored in the storage unit 210. A setting for sharing the video data such as the low resolution material 213 derived from the resolution material 212 and the high resolution video for transmission 214 to the management server 100 is accepted. The image providing server 200 transmits the high resolution material 212 to the management server 100 according to the setting, and transmits the low resolution material 213 to the management server 100 according to the addition of the low resolution material 213 to the storage unit 210. . Further, the video providing server 200 transmits the high resolution video for transmission 213 to the management server 100 according to the setting, in response to the addition of the high resolution video for transmission 214 to the storage unit 210.

  Here, the video providing server 200 may automatically transmit the high res material 212 to the management server 100 when the sharing flag “TRUE” is set for the high res material 212. In addition, the video providing server 200 may automatically transmit the low resolution material 213 to the management server 100 when the low resolution material 213 is stored in the storage unit 210. Furthermore, the video providing server 200 may automatically transmit the high resolution video for transmission 213 to the management server 100 when the high resolution video for transmission 213 is stored in the storage unit 210.

Next, the processing procedure of the management server 100 will be described.
FIG. 10 is a flowchart showing an example of processing of the management server. Hereinafter, the process shown in FIG. 10 will be described in order of step number.

  (S21) The reception processing unit 120 receives the editing status (status) of each video data from the video providing source (video providing server 200), and registers it in the shared video management table 116 stored in the storage unit 110. Thereafter, the reception processing unit 120 receives the changed status from the video providing server 200 at the timing when the editing status changes, and registers the status in the shared video management table 116.

  (S22) The reception processing unit 120 receives a search of the metadata 111 (corresponding to the metadata 211) from the video reception server 300. Specifically, the reception processing unit 120 receives a search query including the metadata 111 from the video reception server 300, refers to the shared video management table 116, and searches the metadata 111 included in the search query.

(S23) The transmission processing unit 140 transmits the retrieved metadata 111 (and the title) to the provision destination (video reception server 300).
(S24) The transmission processing unit 140 refers to the storage unit 110 and determines whether or not the high resolution material, the low resolution material, and the high resolution video for transmission corresponding to the retrieved metadata 111 have been acquired. . If the high resolution material, the low resolution material, and the high resolution transmission image have all been acquired, the transmission processing unit 140 proceeds to step S34. If at least one of the high resolution material, the low resolution material, and the transmission high resolution image has not been acquired, the transmission processing unit 140 proceeds with the process to step S25. Here, the management server 100 may have already acquired the high resolution material, the low resolution material, and the high resolution image for transmission from the image providing server 200 (for example, the user of the A broadcast station 70 manages them in advance) For example, when uploading to the server 100).

(S25) The transmission processing unit 140 transmits a request for the high res material corresponding to the metadata 111 to the video providing server 200 (a request for the high res material to the provider).
(S26) The reception processing unit 120 receives the high resolution material 112 (corresponding to the high resolution material 212) according to the request from the image providing server 200, and stores the high resolution material 112 in the storage unit 110. The reception processing unit 120 registers the received information (file name including path) of the high resolution material 112 in the shared video management table 116.

(S27) The transmission processing unit 140 transmits the high resolution material 112 stored in the storage unit 110 to the video reception server 300.
(S28) The reception processing unit 120 receives the low resolution material 113 (corresponding to the low resolution material 213) corresponding to the high resolution material 112 from the image providing server 200, and stores the low resolution material 113 in the storage unit 110. The reception processing unit 120 registers the received information of the low resolution material 113 in the shared video management table 116.

  (S29) When the low resolution material 113 is stored in the storage unit 110, the transmission processing unit 140 automatically transmits the low resolution material 113 stored in the storage unit 110 to the video reception server 300.

  (S30) The reception processing unit 120 receives, from the video providing server 200, the transmission high resolution image 114 (corresponding to the transmission high resolution image 214) corresponding to the high resolution material 112, and stores the reception high resolution image 114 in the storage unit 110. The reception processing unit 120 registers the information on the received high resolution video for transmission 114 in the shared video management table 116. Further, the reception processing unit 120 registers the status “edited” for the metadata 111 in the shared video management table 116.

  (S31) The conversion unit 130 detects that the video reception server 300 has specified an encoding format different from the high resolution video for transmission 114 as the encoding format for broadcasting. For example, in the storage unit 110, an encoding format used for broadcast by the video reception server 300 is registered in advance. Alternatively, the search query in step S22 may include the encoding format desired by the video reception server 300. In the latter case, the reception processing unit 120 may store the received encoding format in the storage unit 110. The conversion unit 130 transcodes the transmission high resolution video 114 to generate a code conversion video 115 converted to an encoding format used for broadcast by the video reception server 300 and stores the code conversion video 115 in the storage unit 110.

(S32) The transmission processing unit 140 sets the current date and time as the use date and time corresponding to the code conversion video 115.
(S33) The transmission processing unit 140 automatically transmits the transcoded code conversion video 115 stored in the storage unit 110 to the video reception server 300. Then, the transmission processing unit 140 proceeds with the process to step S37.

  (S34) The transmission processing unit 140 refers to the shared video management table 116 stored in the storage unit 110, and determines whether the target video data has been used. If it has been used, the transmission processing unit 140 proceeds to step S38. If it has not been used, the transmission processing unit 140 proceeds to step S35. The used case is the case where the use date and time has already been set for the target video data. The case of not being used means the case where the use date and time is not set for the target video data. In addition, even if the use date and time has already been set, the transmission processing unit 140 exceptionally performs step S35 when the request station in the shared video management table 116 matches the present provision destination (B broadcast station 80). The process may proceed to (or step S36).

(S35) The transmission processing unit 140 sets the current date and time as the use date and time corresponding to the code conversion video 115.
(S36) The transmission processing unit 140 transmits, to the video reception server 300, target video data corresponding to the retrieved metadata 111 with reference to the shared video management table 116. The target video data includes the high resolution material 112 and the low resolution material 113. Also, the target video data includes the transmission high resolution video 114 or the code conversion video 115. For example, the conversion unit 130 may perform transcoding on the transmission high resolution video 114, and transmit the code conversion video 115 to the video reception server 300 instead of the transmission high resolution video 114.

  (S37) The transmission processing unit 140 cooperates with the video providing server 200 to charge the video receiving server 300 according to the provided video data. Specifically, the transmission processing unit 140 acquires, from the video providing server 200, information on the video providing charge according to the provided video, transmits charging information including the video providing charge to the video receiving server 300, and performs payment processing. Run Then, the transmission processing unit 140 ends the process.

  (S38) The transmission processing unit 140 transmits, to the video reception server 300 that is the request source, a warning notification that the corresponding video data has been used and can not be provided. Then, the transmission processing unit 140 ends the process.

  Here, as in step S38, when the target video data has been used by another broadcasting station, the management server 100 warns the video reception server 300 to that effect, and does not provide the video data. It is conceivable to do so. For example, when there is a contract that content provided to a certain broadcast station is not used by another broadcast station, it is useful in that the content provision against the contract can be suppressed.

  In addition, if the high resolution material 112 has been received in the case of No at step S24, the management server 100 may skip steps S25 and S26 and execute step S27. In this case, the management server 100 requests the video providing server 200 to provide low resolution material, and executes step S28. If both the high resolution material 112 and the low resolution material 113 have been received in the case of step S24 No, the management server 100 skips steps S25 and S26, executes step S27, and skips steps S28 and S29. Then, step S30 may be performed. In this case, the management server 100 requests the video providing server 200 to provide the transmission high resolution video, and executes step S30.

Next, the processing procedure of the video reception server 300 will be described.
FIG. 11 is a flowchart showing an example of processing of the video reception server. The process shown in FIG. 11 will be described below in order of step number.

  (S41) The transmission processing unit 320 transmits a search query of the metadata 311 (corresponding to the metadata 111) to the management server 100. As described above, the search query may include information in an encoding format used for broadcast in the video reception server 300.

  (S42) The reception processing unit 330 receives, from the management server 100, the metadata 311 and the title searched according to the search query. The reception processing unit 330 registers the received metadata 311 and the title in the received video management table 315 stored in the storage unit 310.

  (S43) The reception processing unit 330 receives the high resolution material 312 (corresponding to the high resolution material 112) from the management server 100, and stores the high resolution material 312 in the storage unit 310. The reception processing unit 330 registers the received information of the high resolution material 312 in the received video management table 315.

  (S44) The reception processing unit 330 receives the low resolution material 313 (corresponding to the low resolution material 113) corresponding to the high resolution material 312 from the management server 100, and stores the low resolution material 313 in the storage unit 310. The reception processing unit 330 registers the received information of the low resolution material 313 in the received video management table 315.

  (S45) The reception processing unit 330 receives the transmission high resolution video 314 (corresponding to the code conversion video 115) from the management server 100, and stores it in the storage unit 310. The reception processing unit 330 registers the information on the received high resolution video for transmission 314 in the received video management table 315.

  (S46) The reception processing unit 330 receives charging information from the management server 100. The software that performs the settlement process in the video reception server 300 performs the settlement process on the video provision fee included in the billing information. Then, the reception processing unit 330 ends the process.

In response to the addition, the transmission high resolution video 214 is transmitted to the management server 100.

  In addition, after the management server 100 transmits the high resolution material 112 (corresponding to the high resolution material 212) to the video reception server 300, the high resolution video for transmission 214 (corresponding to the high resolution video for transmission 114) from the video providing server 200. Of the transmission high resolution video 114 or the transcoded code conversion video 115 is automatically transmitted to the video reception server 300. For example, if the encoding format used for broadcast by the video receiving server 300 is the same as the encoding format of the high resolution video for transmission 114, the management server 100 provides the video receiving server 300 with the high resolution video for transmission 114. You may Thus, in addition to the high resolution material 212 and the low resolution material 213, sharing of the transmission high resolution image 214 or the code conversion image 115 can be smoothly performed.

  Further, the management server 100 converts the first encoding format of the video data to be transmitted to the video receiving server 300 into a second encoding format according to the video receiving server 300. For example, the management server 100 may convert the encoding format of the high resolution material 112 and the low resolution material 113 into an encoding format used by editing software on the B broadcast station 80 side. Thus, editing work at the B broadcast station 80 can be smoothly performed. Also, the management server 100 may convert the encoding format of the high resolution video for transmission 114 into the encoding format used for broadcasting on the B broadcast station side. As a result, the broadcasting operation on the B broadcast station 80 can be smoothly performed.

  In addition, after the management server 100 transmits the high resolution material 112 to the video reception server 300, the high resolution material 112, the low resolution material 113, the high resolution video for transmission 114, and the code conversion for devices other than the video reception server 300. Transmission of video data including the video 115 is restricted. This can prevent unauthorized use of provided video data by another broadcast station against a contract or the like.

  Furthermore, the management server 100 transmits to the video reception server 300 information of the billing amount according to the transmission of the video data including the high resolution material 112, the low resolution material 113, the high resolution video for transmission 114 and the code conversion video 115. . By this, it becomes possible to smoothly carry out billing according to the content sharing between the broadcast stations in the video data sharing system.

Next, a specific example of transmission of video data by the management server 100 will be described.
FIG. 13 is a diagram illustrating a transmission example (part 1) of video data. As an example, the video reception server 300 requests the management server 100 for a search query of the metadata “original”. The management server 100 retrieves the metadata “original” from the shared video management table 116, and responds to the video reception server 300 with the metadata “original”, the title “team G vs. team T” and the status “editing”. Note that as a metadata search method, various methods such as partial match search for a character string of a search query, AND search for a plurality of character strings, OR search for a plurality of character strings can be considered. Also, the management server 100 registers “B broadcast station” as a request station in the shared video management table 116 for the corresponding metadata “original” and the title “team G vs. team T”.

  The video reception server 300 receives the retrieved metadata “original”, the title “team G vs. team T” and the status “editing”. The video reception server 300 registers the record of the title “Team G vs. Team T”, the metadata “Original” and the status “Editing” in the received video management table 315. At this stage, the high resolution material, low resolution material, and high resolution for transmission items in the record are not set.

  The management server 100 receives the file (file name “haraS. Mov”) of the high resolution material of the metadata “original” from the video providing server 200, and stores the file in the storage unit 110. The management server 100 registers “haraS. Mov” (a file name including a path) in the shared video management table 116. The management server 100 transmits the high resolution material file “haraS. Mov” to the video reception server 300.

  The video reception server 300 receives the file “haraS. Mov” of the high resolution material from the management server 100, and stores the file in the storage unit 310. The video reception server 300 registers “haraS. Mov” in the reception video management table 315.

  FIG. 14 is a diagram of a second transmission example of video data. The management server 100 receives the file (file name “haraL. Mov”) of the low resolution material of the metadata “original” from the video providing server 200, and stores the file in the storage unit 110. The management server 100 registers “haraL. Mov” in the shared video management table 116. The management server 100 automatically transmits the low resolution material file “haraL. Mov” to the video reception server 300.

  The video reception server 300 receives the low resolution material file “haraL. Mov” from the management server 100 and stores the file “hara L. mov” in the storage unit 310. The video reception server 300 registers “haraL. Mov” in the reception video management table 315.

  FIG. 15 is a diagram illustrating a transmission example (part 3) of video data. The management server 100 receives the file (the file name “haraH. Mov”) for transmission of the metadata “original” from the video providing server 200, and stores the file in the storage unit 110. The management server 100 registers “haraH. Mov” and status “edited” in the shared video management table 116 for the video data of the metadata “original” and the title “Team G vs. team T”.

  The management server 100 detects that the encoding format used for broadcasting in the video reception server 300 is “.DVC” instead of “.mov”. For example, as described above, the encoding format desired by the video reception server 300 may be stored in advance in the storage unit 110, or when the management server 100 receives a metadata search query, the video reception server 300 The specification of the encoding format may be accepted.

  Then, the management server 100 transcodes “haraH. Mov” from the file with the extension “. Mov” to the file with the extension “. DVC”. By transcoding, the management server 100 generates a transcoded video “haraH.DVC” after code conversion (conversion from .mov to .DVC), and stores it in the storage unit 110. The management server 100 registers “haraH.DVC” in the shared video management table 116. Furthermore, since the management server 100 sends the file of “haraH.DVC” to the video reception server 300, the current date (“2015 /” in the example of FIG. Set 10/8 17:00 ”). The management server 100 transmits the file “haraH.DVC” of the image after transcoding (transcoded video) and the status “edited” to the video reception server 300.

  The video reception server 300 receives from the management server 100 the file “haraH.DVC” of the image after transcoding (transcoded video) and the status “edited”. Here, the video reception server 300 stores “haraH.DVC” in the storage unit 310. The video reception server 300 registers “haraH.DVC” in the received video management table 315 as the transmission high resolution video. Also, the video reception server 300 registers the status “edited” in the received video management table 315 for the video data received this time. Thereafter, the video reception server 300 cooperates with the management server 100 to perform payment processing for the present video provision.

  Thus, the user of the B broadcast station 80 can edit the high res material "haraS. Mov" while checking each scene using the low res material "hara L. mov" provided from the A broadcast station 70. . One example of editing may be extracting a plurality of highlight scenes and creating an image combining the extracted attractions. Alternatively, if the time of the high resolution transmission image "haraH.DVC" does not exceed the length scheduled in the program, the user of the B broadcast station 80 can directly transmit the high resolution image "haraH.DVC" for transmission. It may be used for broadcasting.

According to the video data sharing system or the management server 100 of the second embodiment, video data can be shared efficiently. Specifically, it is as follows.
As described above, video data held by the A broadcast station 70 (or a video production company) may be acquired by the B broadcast station 80 and edited by the B broadcast station 80 for broadcast. The video data for editing includes a high resolution high resolution material to be edited and a low resolution low resolution material. Here, when video data is shared between broadcast stations or between a video production company and a broadcast station, the presence / absence of video data and the editing status at the provider / destination are provided between the users of the provider / destination. In many cases, video data is provided as needed from the provider to the provider at the discretion of the user while confirming each other. However, in this method, there is a problem that it takes time to cooperate between the providing source user and the providing destination user, and video data can not be shared efficiently.

  Therefore, in the video data sharing system according to the second embodiment, the management server 100 holds the high res material 112 of the specific metadata 111 (video theme) received from the video providing server 200. Then, the management server 100 transmits the high resolution material 112 in response to the request of the video reception server 300, and then receives the low resolution material 113 of the metadata 111 from the video providing server 200, the low resolution material 113 is received Send to 300 automatically. By this, for example, it is possible to save labor of cooperative work for providing video data while confirming the editing status between the user of A broadcast station 70 and the user of B broadcast station 80, and to efficiently share video data. it can. In particular, video data can be shared timely (timely). Further, charging can be efficiently performed according to the provision of video data.

  The information processing of the first embodiment can be realized by causing a program corresponding to the control units 12 and 22 to execute the program. The information processing of the second embodiment can be realized by causing the processors of the management server 100, the video providing server 200, and the video receiving server 300 to execute programs. The program can be recorded on a computer readable recording medium 53.

  For example, the program can be distributed by distributing the recording medium 53 recording the program. Also, the program may be stored in another computer and distributed via a network. For example, the computer stores (installs) a program recorded in the recording medium 53 or a program received from another computer in a storage device such as the RAM 102 or the HDD 103, and reads and executes the program from the storage device. Good.
