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 device.

Broadcasting stations that handle video data use a media asset management (MAM) system for managing video data. The MAM system supports management such as storage and editing of video data in a broadcasting station.

For example, information on the broadcast date and time for the video data that is the material of the broadcast video of the program is received from each of the plurality of terminals connected via the network, and the video data is received from the plurality of terminals based on the broadcast date and time information. There is a proposal for a storage device that determines the order in which data is received. In this proposal, by receiving video data from any of a plurality of terminals according to the determined order, it is possible to preferentially edit the video data having a short grace time until the program broadcast.

There is also a proposal for a system that supports the joint production of media configurations by multiple users. The proposal envisions a two-way project synchronization service that synchronizes the assets of a synchronous media project stored on the client with the assets of the synchronous media project stored on the server.

In addition, 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).

The video data sharing system 1 includes an information processing device 10 and a video data providing device 20. Further, 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 moving image data by the video data providing device 20 and the video data receiving device 30. The information processing device 10 may be referred to as a video data sharing device.

The information processing device 10 has a storage unit 11 and a control unit 12. The video data providing device 20 has a storage unit 21 and a control unit 22.
The storage units 11 and 21 may be a volatile storage device such as a RAM (Random Access Memory) or a non-volatile storage device such as an HDD (Hard Disk Drive) or a flash memory. The control units 12 and 22 may include a CPU (Central Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), and the like. The control units 12 and 22 may be processors that execute programs. A "processor" may also include a set of multiple processors (multiprocessors). The video data receiving device 30 also has a storage unit and a control unit (not shown), like the information processing device 10 and the video data providing device 20.

The storage unit 21 can store the first video data of the first resolution and the second video data of the second resolution generated based on the first video data for a specific video theme. .. For example, the first video data is a video captured by a first user who uses the video data providing device 20 using an image pickup device such as a camera, or a video created by a first user using a computer (for example,). , Animation, etc.) data. The second resolution of the second video data is, for example, lower than the first resolution of the first video data. Further, 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, and the like.

The control unit 22 stores the specific video data in the storage unit 21 in a state where the first video data is stored in the storage unit 21 but the second video data is not stored in the storage unit 21. Accepts the setting to share data with the information processing device 10. The control unit 22 transmits the first video data to the information processing device 10 according to the setting, and transmits the second video data to the information processing device 10 according to the addition of the second video data to the storage unit 21. Controls the transmission to.

For example, the first user can input a setting for sharing the first video data by using an input device (not shown) connected to the video data providing device 20. The control unit 22 transmits the first video data to the information processing device 10 according to the setting (step Sa1). After that, the control unit 22 controls 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 or may be generated by another computer connected to the video data providing device 20 based on the first video data.

Then, the control unit 22 controls to transmit the second video data to the information processing apparatus 10 in response to the addition of the second video data to the storage unit 21 (step Sa3). For example, the control unit 22 may automatically transmit the second video data to the information processing device 10 when the second video data is added to the storage unit 21. Alternatively, the control unit 22 transfers the second video data to the information processing device 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 received. You may send it.

The storage unit 11 stores the first video data about a specific video theme received from the video data providing device 20.
The control unit 12 controls to receive the first video data about a specific video theme from the video data providing device 20 and store it 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 device 30 in response to a request from the video data receiving device 30 for a specific video theme, and then the video data providing device. When the second video data is received from the 20th, the control for automatically transmitting the second video data to the video data receiving device 30 is performed. Here, the video data receiving device 30 is another device different from the information processing device 10 and the video data providing device 20.

For example, the control unit 12 receives a request for a specific video theme from the video data receiving device 30, and searches for the first video data stored in the storage unit 11 corresponding to the specific video theme. Then, the control unit 12 transmits the searched first video data to the video data receiving device 30 (step Sb1). At the stage of step Sb1, the second video data has not yet been received by the information processing apparatus 10. After step Sb1, the control unit 12 controls to automatically transmit the second video data to the video data receiving device 30 when the second video data is received from the video data providing device 20 (step Sb2). Further, the control unit 12 also controls to store the received second video data in the storage unit 11 for the subsequent sharing of the video data.

According to the video data sharing system 1, video data can be efficiently shared. Specifically, it is as follows.
Here, the video data held by one broadcasting station (or a video production company may be used) may be acquired by another broadcasting station and edited for broadcasting by another broadcasting station. In this case, the video data providing device 20 belongs to a certain broadcasting station (or a video production company). The video data receiving device 30 belongs to another broadcasting station. The video data for editing includes, for example, a high-resolution first video data to be edited and a low-resolution second video data used for confirming each scene in the first video data. included. When sharing video data between the broadcasting station of the provider and the broadcasting station of the provider, the existence of the video data and the editing status at the provider / provider are confirmed by the users who work at the provider / provider. At the same time, video data is provided from the provider to the provider at the discretion of the user. However, this method has a problem that it takes time to collaborate between the users of the provider / the provider and the video data cannot 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. When the information processing device 10 transmits the first video data in response to the request of the video data receiving device 30 and then receives the second video data of the second resolution of the same theme from the video data providing device 20, the information processing device 10 receives the second video data. The video data of 2 is automatically transmitted to the video data receiving device 30. As a result, it is possible to save labor in collaborating to provide video data while confirming the editing status between the user who uses the video data providing device 20 and the user who uses the video data receiving device 30, and the sharing of video data is efficient. Can be transformed into. In particular, as soon as various video data are created by the broadcasting station of the provider, 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 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 exerts the functions of the reception processing unit 120, the conversion unit 130, and the transmission processing unit 140 by executing the program stored in the RAM 102. Alternatively, the reception processing unit 120, the conversion unit 130, and the transmission processing unit 140 may be realized by hard-wired logic such as FPGA or ASIC.

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

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

The high-resolution video 114 for transmission is the edited video data obtained by editing the high-resolution material 112 by the video providing server 200. The high-resolution video 114 for transmission is created from the high-resolution material 112 by the video providing server 200.

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

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

The video providing server 200 has 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 included 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 exerts the functions of the transmission processing unit 220 and the reception processing unit 230 by executing the 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 214 for transmission. The metadata 211 is set for the high resolution material 212 by the user of the A broadcasting station 70. The high resolution material 212 is high-resolution video data acquired by the A broadcasting 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 high-resolution video 214 for transmission is video data after editing of the high-resolution material 212 by the user of the A broadcasting 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 214 for transmission stored in the storage unit 210 to the management server 100.

When the reception processing unit 230 acquires the video data of the B broadcasting 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 has a storage unit 310, a transmission processing unit 320, and a reception processing unit 330.

The storage unit 310 is realized by the storage area of the RAM or HDD included in the video receiving 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 exerts the functions of the transmission processing unit 320 and the reception processing unit 330 by executing the program stored in the RAM included in the video reception server 300. 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 metadata 311, high resolution material 312, low resolution material 313, and high resolution video 314 for transmission. The metadata 311 is the 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 high-resolution video 314 for transmission is the edited video data of the high-resolution material 312 provided by the video providing server 200. The high-resolution video for transmission 314 may be the same as the high-resolution video for transmission 214 (and the high-resolution video for transmission 114), or the same as the code-converted video 115 after transcoding by the management server 100. In some cases.

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

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

The high resolution material 212 is high-resolution video data taken by a camera provided in a baseball field. For example, the high resolution material 212 includes a three-hour video taken from the start of the match to the end of the match. In addition, the high resolution material 212 includes three highlight scenes such as home runs. The high resolution material 212 can be edited by another broadcasting station (for example, B broadcasting station 80) provided with the high resolution material 212.

The low resolution material 213 is created by reducing the resolution of the high resolution material 212 by the video providing server 200. The low resolution material 213, like the high resolution material 212, includes a three-hour video shot from the start of the match to the end of the match. By reducing the resolution, the data size of the low resolution material 213 becomes smaller than the data size of the high resolution material 212. Therefore, in the work of extracting one scene in the entire video, such as confirmation of the highlight scene, the software used for the work is better to use the low resolution material 213 than to use the high resolution material 212. The processing load is reduced and the work can be done efficiently (for example, fast).

The high resolution image 214 for transmission is generated based on the high resolution material 212. The high-resolution image 214 for transmission is an image in which, for example, three highlight scenes in the high-resolution material 212 are extracted and connected without degrading the resolution of the high-resolution material 212. Therefore, the time from the start to the end of the high-resolution video 214 for transmission is shorter than the time from the start to the end of the high-resolution material 212. The high resolution video 214 for transmission is edited so as to have a predetermined time (for example, 3 minutes or the like). If the predetermined time of the high-resolution video for transmission 214 matches the scale scheduled for the program, the B broadcasting station 80 that has received the high-resolution video for transmission 314 corresponding to the high-resolution video for transmission 214 sends. It is also possible to broadcast the high-credit resolution video 314 as it is to the viewer in the program.

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

The title of the video data is registered in the title item. Metadata is registered in the metadata item. The identification name (file name) of the file of the high resolution material is registered in the item of the high resolution material. The file name of the low resolution material is registered in the item of the low resolution material. If the low resolution material corresponding to the high resolution material does not yet exist, the item of the low resolution material is not set (indicated by the "-" hyphen symbol). The file name of the high-resolution video for transmission is registered in the item of the high-resolution video for transmission. If the high-resolution video for transmission corresponding to the high-resolution material does not yet exist, the item of the high-resolution video for transmission is not set. In the status item, a status indicating the editing status of the video data in the video providing server 200 is registered. Statuses include, for example, "not created", "editing", and "edited". "Not created" indicates that the creation of high-resolution video for transmission has not been started. "Editing" indicates that a high-resolution video for transmission is being created. "Edited" indicates that a high-resolution video for transmission has been created. In the item of the sharing flag, a sharing flag indicating whether or not to allow sharing of the video data with other broadcasting stations 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 shared flag is "FALSE".

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

This indicates that the metadata "Nagashima" is attached to the video data titled "Team G vs. Team T". In addition, the title and metadata set are compatible with high-resolution material with the file name "nagasimaS.mov", low-resolution material with the file name "nagasimaL.mov", and high-resolution video for transmission with the file name "nagasimaH.mov". Show that you do. Further, it indicates that a high-resolution video for transmission for the high-resolution material “nagasimaS.mov” has been created (status “edited”) and sharing of video data is permitted (sharing flag “TRUE”).

FIG. 7 is a diagram showing an example of a shared video management table. The shared video management table 116 is stored in the storage unit 110.

Further, 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. Further, the video providing server 200 may automatically transmit the high resolution video 213 for transmission to the management server 100 when the high resolution video 213 for transmission 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 a processing example of the management server. Hereinafter, the process shown in FIG. 10 will be described along with the step numbers.

(S21) The reception processing unit 120 receives the editing status (status) of each video data from the video provider (video providing server 200) and registers it in the shared video management table 116 stored in the storage unit 110. After that, 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 changed status in the shared video management table 116.

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

(S23) The transmission processing unit 140 transmits the searched metadata 111 (and the title) to the provider (video receiving 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 searched metadata 111 have been acquired. .. When all of the high resolution material, the low resolution material, and the high resolution video for transmission have been acquired, the transmission processing unit 140 proceeds to the process in step S34. If at least one of the high resolution material, the low resolution material, and the high resolution video for transmission has not been acquired, the transmission processing unit 140 proceeds to the process in step S25. Here, the management server 100 may have acquired all of the high-resolution material, the low-resolution material, and the high-resolution video for transmission from the video providing server 200 (for example, the user of the A broadcasting station 70 manages them in advance. When uploading to server 100, etc.).

(S25) The transmission processing unit 140 transmits a request for the high-resolution material corresponding to the metadata 111 to the video providing server 200 (request to the provider for the high-resolution material).
(S26) The reception processing unit 120 receives the high resolution material 112 (corresponding to the high resolution material 212) in response to the request from the video providing server 200 and stores it in the storage unit 110. The reception processing unit 120 registers the received information (file name including the 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 receiving 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 video providing server 200 and stores it 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 receiving server 300.

(S30) The reception processing unit 120 receives the transmission high-resolution video 114 (corresponding to the transmission high-resolution video 214) corresponding to the high-resolution material 112 from the video providing server 200 and stores it in the storage unit 110. The reception processing unit 120 registers the received information of the high-resolution video 114 for transmission 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 receiving server 300 specifies an encoding format different from the high-resolution video for transmission 114 as the encoding format for broadcasting. For example, an encoding format used for broadcasting in the video receiving server 300 is registered in advance in the storage unit 110. Alternatively, the search query in step S22 may include the encoding format desired by the video receiving 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 high-resolution video 114 for transmission to generate a code-converted video 115 converted into an encoding format used for broadcasting by the video reception server 300, and stores the code-converted video 115 in the storage unit 110.

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

(S34) The transmission processing unit 140 determines whether or not the target video data has been used by referring to the shared video management table 116 stored in the storage unit 110. 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 case where it has been used is a case where the date and time of use has been set for the target video data. The case where it has not been used is the case where the date and time of use has not been set for the target video data. Even if the date and time of use has already been set, the transmission processing unit 140 is exceptionally in step S35 when the request station of the shared video management table 116 matches the current provision destination (B broadcasting station 80). The process may proceed to (or step S36).

(S35) The transmission processing unit 140 sets the current date and time as the usage date and time corresponding to the code conversion video 115.
(S36) The transmission processing unit 140 refers to the shared video management table 116 and transmits the target video data corresponding to the searched metadata 111 to the video receiving server 300. The target video data includes the high resolution material 112 and the low resolution material 113. Further, the target video data includes a high resolution video 114 for transmission or a code conversion video 115. For example, the conversion unit 130 may transcode the high-resolution video 114 for transmission and transmit the code-converted video 115 to the video reception server 300 instead of the high-resolution video 114 for transmission.

(S37) The transmission processing unit 140 cooperates with the video providing server 200 to perform billing processing to the video receiving server 300 according to the provided video data. Specifically, the transmission processing unit 140 acquires information on the video provision fee according to the provided video from the video provision server 200, and transmits the billing information including the video provision fee to the video reception server 300 for payment processing. To execute. Then, the transmission processing unit 140 ends the processing.

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

Here, as in step S38, when the target video data has been used by another broadcasting station, the management server 100 warns the video receiving 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 the content provided to one broadcasting station is not used by another broadcasting station, it is useful in that the provision of content contrary to the contract can be suppressed.

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

In this way, in addition to the high resolution material 212 and the low resolution material 213, the high resolution video 214 for transmission or the code conversion video 115 can be smoothly shared.

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

Further, after transmitting the high resolution material 112 to the video receiving server 300, the management server 100 transmits the high resolution material 112 to the devices other than the video receiving server 300, the low resolution material 113, the high resolution video 114 for transmission, and the code conversion. Restrict the transmission of video data including video 115. As a result, it is possible to prevent the provided video data from being illegally used by another broadcasting station, contrary to a contract or the like.

Further, the management server 100 transmits to the video receiving server 300 information on the charge amount according to the transmission of the video data including the high resolution material 112, the low resolution material 113, the high resolution video 114 for transmission, and the code conversion video 115. .. As a result, in the video data sharing system, it becomes possible to smoothly charge according to the content sharing between broadcasting stations.

Next, a specific example of transmission of video data by the management server 100 will be described.
FIG. 13 is a diagram showing an example of transmission of video data (No. 1). As an example, the video receiving server 300 requests the management server 100 to search for the metadata “original”. The management server 100 searches for the metadata "original" from the shared video management table 116, and responds to the video receiving server 300 with the metadata "original", the title "team G vs. team T", and the status "editing". As a method for searching metadata, various methods such as a partial match search for a character string in a search query, an AND search for a plurality of character strings, and an OR search for a plurality of character strings can be considered. Further, the management server 100 registers "B broadcasting 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 receiving server 300 receives the searched metadata "original", the title "team G vs. team T", and the status "editing". The video receiving 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 items of high resolution material, low resolution material, and high resolution for transmission in the record are not set.

The management server 100 receives a high-resolution material file (file name “haraS.mov”) of the metadata “original” from the video providing server 200 and stores it 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 file "haraS.mov" of the high resolution material to the video receiving server 300.

The video receiving server 300 receives the high resolution material file "haraS.mov" from the management server 100 and stores it in the storage unit 310. The video receiving server 300 registers "haraS.mov" in the received video management table 315.

FIG. 14 is a diagram showing an example of transmission of video data (No. 2). The management server 100 receives a low-resolution material file (file name “haraL.mov”) of the metadata “original” from the video providing server 200 and stores it 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 receiving server 300.

The video receiving server 300 receives the low resolution material file "haraL.mov" from the management server 100 and stores it in the storage unit 310. The video receiving server 300 registers "haraL.mov" in the received video management table 315.

FIG. 15 is a diagram showing an example of transmission of video data (No. 3). The management server 100 receives a high-resolution video file for transmission (file name “haraH.mov”) of the metadata “original” from the video providing server 200 and stores it in the storage unit 110. The management server 100 registers "haraH.mov" and the 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 receiving server 300 is ".DVC" instead of ".mov". For example, as described above, the encoding format desired by the video receiving server 300 may be stored in advance in the storage unit 110, and when the management server 100 receives the metadata search query, the video receiving server 300 may store the encoding format. You may accept the specification of the encoding format.

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 the transcoded video "haraH.DVC" after the 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. Further, since the management server 100 sends the file of "haraH.DVC" to the video receiving server 300, the current date and time ("2015 / in the example of FIG. 15" is added to the item of the usage date and time of the shared video management table 116. 10/8 17:00 ") is set. The management server 100 transmits the code-converted image (transcoded video) file “haraH.DVC” and the status “edited” to the video receiving server 300.

The video receiving server 300 receives the file "haraH.DVC" of the code-converted image (transcoded video) and the status "edited" from the management server 100. Here, the video receiving server 300 stores "haraH.DVC" in the storage unit 310. The video receiving server 300 registers "haraH.DVC" as a high-resolution video for transmission in the received video management table 315. Further, the video receiving server 300 registers the status "edited" in the received video management table 315 for the video data provided this time. After that, the video receiving server 300 cooperates with the management server 100 to perform payment processing for the video provision this time.

In this way, the user of the B broadcasting station 80 can edit the high resolution material "haraS.mov" while checking each scene by using the low resolution material "haraL.mov" provided by the A broadcasting station 70. .. As one example of editing, it is conceivable to extract a plurality of highlight scenes and create a video in which the extracted plurality of highlights are combined. Alternatively, if the time of the high-resolution video for transmission "haraH.DVC" does not exceed the planned scale in the program, the user of the B broadcasting station 80 uses the high-resolution video for transmission "haraH.DVC" as it is. It may be used for broadcasting.

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

Therefore, in the video data sharing system of the second embodiment, the management server 100 holds the high resolution material 112 of the specific metadata 111 (video theme) received from the video providing server 200. Then, when the management server 100 transmits the high resolution material 112 in response to the request of the video receiving server 300 and then receives the low resolution material 113 of the metadata 111 from the video providing server 200, the management server 100 receives the low resolution material 113 from the video receiving server. Automatically send to 300. As a result, for example, it is possible to save labor in collaborating to provide video data while confirming the editing status between the user of broadcasting station A 70 and the user of broadcasting station B 80, and it is possible to improve the efficiency of sharing video data. can. In particular, video data can be shared in a timely manner (timely). Further, it is possible to efficiently charge according to the provision of video data.
