  The camera 15 is a camera capable of shooting a moving image, and is, for example, a Web camera or a digital video camera. In an example of the present embodiment, the camera 15 only needs to be able to record data including at least one of moving image data 150 (described later using FIG. 2 and the like) and audio data. Therefore, the camera 15 may be integrated with a microphone (not shown), or a microphone may be provided instead of the camera 15. In the following description of an example of the embodiment, it is assumed that the terminal 10 records moving image data 150 photographed by the camera 15. In addition to moving image data and audio data, other data that is meaningful in terms of time or order may be used.

The GPS sensor 16 is an example of a position information acquisition device that acquires position information of the terminal 10. The GPS sensor 16 acquires position information of the terminal 10 at the time of shooting a moving image by the camera 15 as GPS information.
The input device 17 is, for example, a mouse, a trackball, or a keyboard, and the user performs various input operations via the input device 17.

The storage device 13 is a known device that stores data in a readable / writable manner, and is, for example, a Hard Disk Drive (HDD) or a Solid State Drive (SSD). In an example of the present embodiment, the storage device 13 stores moving image data 150 captured by the camera 15, for example.
The medium reader 14 is configured so that a recording medium RM can be loaded. The medium reader 14 is configured to be able to read information recorded on the recording medium RM when the recording medium RM is mounted. In this example, the recording medium RM has portability. The recording medium RM is a computer-readable recording medium such as a flexible disk, CD (CD-ROM, CD-R, CD-RW, etc.), DVD (DVD-ROM, DVD-RAM, DVD-R, etc.). DVD + R, DVD-RW, DVD + RW, HD DVD, etc.), Blu-ray disc, magnetic disc, optical disc, magneto-optical disc, or semiconductor memory. In an example of this embodiment, the medium reading device 14 stores moving image data 150 photographed by the camera 15, for example.

  The I / F 19 is an interface device that connects the terminal 10 to the network 100 and communicates with the server 20 and an external device (not shown) via the network 100. In an example of the present embodiment, it is assumed that communication between the terminal 10 and the network 100 is disconnected due to deterioration of radio wave conditions, increase in traffic, or the like. Therefore, as the I / F 19, for example, various interface cards corresponding to the standards of the wireless local area network (LAN), the wireless wide area network (WWAN), and the telephone network 100 can be used.

  The memory 12 is a storage device including a read only memory (ROM) and a random access memory (RAM). A program such as Basic Input / Output System (BIOS) is written in the ROM of the memory 12. The software program on the memory 12 is appropriately read and executed by the CPU 11. The RAM of the memory 12 is used as a primary recording memory or a working memory.

The CPU 11 is a processing device that performs various controls and calculations, and implements various functions by executing an operating system (OS) and programs stored in the memory 12. That is, the CPU 11 functions as a recording processing unit 111, a transmission unit 112, a reception unit 113, and a reproduction unit 114 as shown in FIG.
Note that a program (data transmission program) for realizing the functions as the recording processing unit 111, the transmitting unit 112, the receiving unit 113, and the reproducing unit 114 is provided in a form recorded on the recording medium RM described above, for example. The Then, the computer reads the program from the recording medium RM via the medium reading device 14, transfers it to the internal storage device or the external storage device, and uses it. Alternatively, the program may be recorded in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provided to the computer from the storage device via a communication path.

When realizing the functions as the recording processing unit 111, the transmission unit 112, the reception unit 113, and the reproduction unit 114, the program stored in the internal storage device (the memory 12 in this embodiment) is stored in the microprocessor of the computer (this embodiment). In the form, it is executed by the CPU 11). At this time, the computer may read and execute the program recorded on the recording medium.
The recording processing unit 111 records identification information in the moving image data 150 captured by the camera 15. Specifically, the recording processing unit 111 intermittently embeds identification information in the moving image data 150 using a general technique for inserting chapters into moving image data. Further, the recording processing unit 111 stores the moving image data 150 in which the identification information is recorded in the storage device 13 or the recording medium RM. For example, the user can arbitrarily set the storage destination of the moving image data 150 in the terminal 10.

FIG. 2 is a diagram illustrating identification information recording processing and data transmission processing in the network system as an example of the embodiment. FIG. 3 is a diagram illustrating identification information in the network system as an example of the embodiment.
As illustrated in FIG. 2, the recording processing unit 111 records (embeds) a plurality (20 in the illustrated example) of identification information # 1 to # 20 at predetermined intervals in the moving image data 150.

In the following, when the moving image data 150 is illustrated, the left side of the drawing is the beginning (first) of the moving image data 150, and the right side of the drawing is the end (last) of the moving image data 150.
As shown in FIG. 3, the identification information includes, for example, user identification information (user ID; UserID), terminal ID (TerminalID), time information (DATE), and GPS information (GPSLatitudeRef, GPSLatitude, GPSLongitudeRef and GPSLongitude), and a tag It is described by.

  The user ID is an ID of a user who uses the terminal 10, the terminal ID is an ID unique to the terminal 10, the time information is information indicating the date and time when the identification information is recorded, and the GPS information is moving image data. Reference numeral 150 denotes position information of the place where the image was taken. Accordingly, the pieces of identification information are different from each other and have an order in time series. It is desirable that the minimum unit of time information includes at least seconds.

For example, in the identification information # 1, the user ID is Shira, the terminal ID is 0002, the time information is 14:40:10 on June 18, 2013, and the GPS information is 35 degrees 41 north latitude. Min 7.74 seconds / Eastern longitude 139 degrees 48 minutes 7.74 seconds.
For example, the recording processing unit 111 acquires a user ID and a terminal ID stored in the storage device 13, acquires time information from a clock (not shown) included in the terminal 10, and acquires GPS information from the GPS sensor 16. Then, the recording processing unit 111 records the acquired user ID, terminal ID, time information, and GPS information as identification information in the moving image data 150 every predetermined time (every 5 seconds in the example shown in FIG. 3). Note that the interval at which the identification information is recorded in the moving image data 150 may be set when the terminal 10 or the data transmission program is shipped from the factory, or may be arbitrarily set by the user.

That is, the recording processing unit 111 intermittently records a plurality of pieces of identification information including different time information in the data during shooting of the moving image.
The transmission unit 112 transmits the moving image data 150 in which the identification information is recorded to the server 20, for example, wirelessly.
The above processing by the recording processing unit 111 and the transmission unit 112 can be performed in real time in parallel with the shooting of the moving image data 150 by the camera 15.

  As shown in FIG. 2, the transmission unit 112 transmits (uploads) the moving image data 150 in which the recording processing unit 111 has recorded the identification information to the cloud 200 in real time (see reference numerals A11 and # 001). The cloud 200 is a computer resource configured by the server 20 and a storage device 23 described later. Hereinafter, the portion of the moving image data 150 that is transmitted in real time in parallel with the recording of the identification information may be referred to as real time transmission data.

  Here, if the communication between the terminal 10 and the network 100 is disconnected after transmitting the moving image data 150 up to the identification information # 5 during transmission of the moving image data 150 (see reference A1), the recording processing unit 111 Of the video data 150, unsent data is stored in the terminal 10. Specifically, the recording processing unit 111 stores, in the storage device 13 or the recording medium RM, the data after the last identification information # 5 that can be transmitted on the cloud 200 in the moving image data 150. Hereinafter, “data after identification information # 5” as described above includes identification information # 5. Note that the recording processing unit 111 may store not only the untransmitted moving image data 150 but also all the recorded moving image data 150 in the storage device 13 or the recording medium RM.

When the terminal 10 is reconnected to the network 100 (see symbol A2), the transmission unit 112 transmits the data after the identification information # 11 recorded immediately before the network reconnection on the cloud 200 in the moving image data 150. Is transmitted in real time (see symbol A13, # 003).
Further, in parallel with the transmission of the data indicated by reference signs A13 and # 003, the transmission unit 112 reads out, from the storage device 13 or the recording medium RM, the data that could not be transmitted due to the network disconnection from the moving image data 150, and the cloud 200 (See reference sign A12, # 002). That is, in parallel with the transmission of the real-time transmission data, the transmission unit 112 transmits data on the cloud 200 until the network after the identification information # 5 is reconnected (see symbol A2). Send to. Hereinafter, the data of the moving image data 150 that is read from the storage device 13 or the recording medium RM and transmitted is sometimes referred to as delayed transmission data. Hereinafter, the real-time transmission data and the delayed transmission data may be collectively referred to as partial data.

  Here, the beginning of the delayed transmission data # 002 is identification information # 5 recorded at the end of the real-time transmission data # 001, and the last identification information of the real-time transmission data # 001 and the first identification information of the delay transmission data # 002. Is the same (see symbol A21). The head of the real-time transmission data # 003 is identification information # 11 recorded at the end of the delay transmission data # 002. The last identification information of the delay transmission data # 002 and the first identification information of the real-time transmission data # 003 Are the same (see reference A22).

  Further, when the communication between the terminal 10 and the network 100 is disconnected (see symbol A3), the recording processing unit 111 stores untransmitted data in the terminal 10 in the moving image data 150. Specifically, the recording processing unit 111 stores, in the storage device 13 or the recording medium RM, the data after the last identification information # 14 that can be transmitted on the cloud 200 in the moving image data 150. Then, when the terminal 10 is connected to the network 100 again at a timing not shown, the transmission unit 112 reads out, from the storage device 13 or the recording medium RM, the data that could not be transmitted due to the network disconnection from the moving image data 150 to the cloud 200 (see reference A14, # 004). That is, the transmission unit 112 transmits data from the identification information # 14 to the end of shooting (the end of the moving image data 150) on the cloud 200 in the moving image data 150. Here, the head of the delayed transmission data # 004 is identification information # 14 recorded at the end of the real-time transmission data # 003, and the last identification information of the real-time transmission data # 003 and the first identification information of the delay transmission data # 004. Is the same (see symbol A23).

  That is, the transmission unit 112 transmits first data (for example, real-time transmission data # 001) that is a part of data and includes at least one piece of identification information to the server 20. In addition, when communication with the server 20 is interrupted, the transmission unit 112 is a part of the data after the identification information (for example, identification information # 5) recorded at the end of the first data after the communication is restored. The second data (for example, delayed transmission data # 002) is transmitted to the server 20.

Note that the determination of how far the moving image data 150 has been successfully transmitted when the network is disconnected may be made by the transmitting unit 112 inquiring of the server 20 after reconnection to the network, or the terminal 10 may manage the transmission progress status.
The receiving unit 113 receives (downloads) the moving image data 150 from the server 20.
When the transmission unit 112 makes an inquiry to the server 20 after reconnecting to the network to determine how far the video data 150 has been successfully transmitted when the network is disconnected, the reception unit 113 receives the video data 150 from the server 20. Receive the transmission progress.

The reproduction unit 114 performs reproduction processing of the moving image data 150 received by the reception unit 113 and causes the display device 18 to display the reproduction data.
The server 20 is a computer having a server function, and is connected to a storage device 23 so as to be communicable as shown in FIG.
The storage device 23 is a known device that stores data in a readable / writable manner, and is, for example, an HDD or an SSD. In an example of this embodiment, the storage device 23 stores moving image data 150 (a plurality of partial data) received from the terminal 10. Further, the storage device 23 stores information related to an identification information storage table which will be described later with reference to FIG. In the example shown in FIG. 1, the server 20 is connected to one storage device 23, but the present invention is not limited to this, and the server 20 is connected to two or more storage devices 23. You may do it.

The server 20 includes a CPU 21, a memory 22, and a network interface (I / F) 24, which are connected to each other via a bus (not shown) or the like.
The I / F 24 is an interface device that connects the server 20 to the network 100 and communicates with the terminal 10 and an external device (not shown) via the network 100. As the I / F 24, for example, various interface cards corresponding to the standard of the wired LAN, the wireless LAN, and the WWAN network 100 can be used.

The memory 22 is a storage device including a ROM and a RAM. A program such as BIOS is written in the ROM of the memory 22. The software program on the memory 22 is appropriately read by the CPU 21 and executed. The RAM of the memory 22 is used as a primary recording memory or a working memory.
The CPU 21 is a processing device that performs various controls and operations, and implements various functions by executing an OS and programs stored in the memory 22. That is, the CPU 21 functions as a combination processing unit 211, a transmission unit 212, and a reception unit 213 as illustrated in FIG.

  Note that programs for realizing the functions as the combination processing unit 211, the transmission unit 212, and the reception unit 213 are, for example, a flexible disk, a CD (CD-ROM, CD-R, CD-RW, etc.), a DVD (DVD). -ROM, DVD-RAM, DVD-R, DVD + R, DVD-RW, DVD + RW, HD DVD, etc.), recorded in a computer-readable recording medium such as a Blu-ray disc, magnetic disc, optical disc, magneto-optical disc, etc. Provided. Then, the computer reads the program from the recording medium via a reading device (not shown), transfers the program to the internal recording device or the external recording device, and uses it. Alternatively, the program may be recorded in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provided to the computer from the storage device via a communication path.

When realizing the functions as the combination processing unit 211, the transmission unit 212, and the reception unit 213, the program stored in the internal storage device (memory 22 in the present embodiment) is stored in a microprocessor of the computer (CPU 21 in the present embodiment). Executed by. At this time, the computer may read and execute the program recorded on the recording medium.
The receiving unit 213 receives the moving image data 150 (a plurality of partial data) from the terminal 10. Specifically, the reception unit 213 receives the real-time transmission data and the delayed transmission data transmitted by the terminal 10, attaches a file name (described later with reference to FIG. 4) to each of the received data, and stores the storage device 23. To store.

The combination processing unit 211 combines the plurality of moving image data 150 according to the time series based on the identification information.
FIG. 4 is a diagram illustrating an identification information storage table in the server as an example of the embodiment.
The identification information storage table is a table in which a plurality of identification information recorded in the moving image data 150 and the file names assigned by the receiving unit 213 are stored as records. In the example shown in FIG. 4, the identification information storage table holds 23 records of record Nos. 001 to 023. Each record is associated with a user ID, a terminal ID, a file name, time information, and GPS information.

For example, in the record No. 001, the user ID is Shira, the terminal ID is 0002, the file name is 001.xxx, and the time information is 14:40:10 on June 18, 2013, The GPS information is X1, Y1. Note that xxx at the end of the file name is an extension, and in the case of the moving image data 150, for example, MPEG, MP4, or AVI.
Here, reference numerals # 1 to # 20 attached to the left side of the record No. in the drawing indicate that each record corresponds to the identification information # 1 to # 20 shown in FIG. That is, identification information # 5 included in both real-time transmission data # 001 and delayed transmission data # 002 corresponds to both record No. 005 and record No. 006. In other words, the identification information # 5 is received in duplicate, and the same identification information is stored in record No. 005 and record No. 006. However, since the record No. 005 corresponds to the real-time transmission data # 001, the file name 001.xxx is given by the receiving unit 213, and the record No. 006 corresponds to the delayed transmission data # 002, and the file name 002.xxx. Is attached by the receiving unit 213. Also, for identification information # 11 and # 14, there are two corresponding records, respectively, as in identification information # 5.

The combination processing unit 211 extracts a plurality of pieces of identification information recorded in the partial data from the top of the partial data in the order received, and stores them in the identification information storage table. Then, for example, the combination processing unit 211 sorts the records in the identification information storage table in the order of user ID, terminal ID, time information, and file name to obtain the identification information storage table in the state shown in FIG.
The combination processing unit 211 scans in descending order from the head of the identification information storage table, and includes identification information corresponding to records having the same user ID and terminal ID and the same file name in the same partial data. It is determined as identification information. For example, the record Nos. 001 and 002 have the same user ID Shira, the same terminal ID 0002, and the same file name 001.xxx. Therefore, the combination processing unit 211 determines that the identification information # 1 and # 2 corresponding to the records No. 001 and 002 are identification information included in the same real-time transmission data # 001.

  Further, the combination processing unit 211 determines that identification information corresponding to records having the same user ID and terminal ID and the same time information and GPS information but different file names is the same identification information, The real-time transmission data including the identification information and the delayed transmission data are combined. For example, the records No. 005 and 006 have the same user ID Shira, the same terminal ID 0002, the same file name 001.xxx and 002.xxx, but the time information is June 2013 It is the same at 18: 14: 40: 30 on the 18th, and the GPS information is the same for X4 and Y4. Therefore, the combination processing unit 211 determines that the identification information # 5 corresponding to the records No. 005 and 006 is the same identification information, and combines the real-time transmission data # 001 and the delayed transmission data # 002 including these identification information. (See reference A21 in FIG. 2). Specifically, the combination processing unit 211 sandwiches the identification information # 5 next to the part before the identification information # 5 in the real-time transmission data # 001, and then follows the identification information # 5 in the delayed transmission data # 002. Connect the parts.

Note that when the user interrupts shooting, the time information and the GPS information are not the same in the two files, so the combination processing unit 211 does not combine the real-time transmission data and the delayed transmission data.
Further, the combination processing unit 211 combines the real-time transmission data including the corresponding identification information and the delayed transmission data for the record Nos. 012 and 013 and the record Nos. 016 and 017 as well as the record Nos. 005 and 006. (Refer to reference numerals A22 and A23 in FIG. 2). Then, the combination processing unit 211 obtains the moving image data 150 including all the identification information # 1 to # 20 illustrated in FIG. 2 as one moving image file.

That is, the combination processing unit 211 includes, among the plurality of data, the identification information recorded at the end of the first data (for example, the identification information # 5 of the real-time transmission data # 001 shown in FIG. 2) and the second data When the identification information recorded at the beginning (for example, identification information # 5 of delayed transmission data # 002 shown in FIG. 2) matches, the second data is combined after the first data.
The transmission unit 212 transmits (distributes) the moving image data 150 combined by the combination processing unit 211 to the terminal 10.

[A-2] Operation The identification information recording process in the terminal 10 as an example of the embodiment configured as described above will be described with reference to the flowchart (steps S11 to S15) shown in FIG.
The camera 15 starts shooting the moving image data 150 (step S11).
The recording processing unit 111 determines whether there is a recording area (step S12). For example, the recording processing unit 111 determines whether there is a free space in the storage device 13 or whether the recording medium RM is inserted in the medium reading device 14.

If there is no recording area (see NO route in step S12), the identification information recording process is terminated.
On the other hand, if there is a recording area (see YES route in step S12), it is determined whether a predetermined time (for example, 5 seconds) has elapsed (step S13).
If the predetermined time has not elapsed (see NO route in step S13), the process returns to step S12.

On the other hand, when the predetermined time has elapsed (see YES route in step S13), the recording processing unit 111 acquires identification information (step S14). For example, the recording processing unit 111 acquires a user ID and a terminal ID stored in the storage device 13, acquires time information from a clock (not shown) included in the terminal 10, and acquires GPS information from the GPS sensor 16.
The recording processing unit 111 records the acquired identification information in the moving image data 150 (step S15), and returns to step S12.

Next, a data transmission process in the terminal 10 as an example of the embodiment will be described according to a flowchart (steps S21 to S24) illustrated in FIG.
The transmission processing unit 112 determines whether the terminal 10 can be connected to the network 100 (step S21).
If the terminal 10 cannot be connected to the network 100 (see NO route in step S21), the recording processing unit 111 stores the delayed transmission data in the storage device 13 or the recording medium RM connected to the terminal 10 (step S22). ), The process returns to step S21.

On the other hand, when the terminal 10 can be connected to the network 100 (see YES route in step S21), the transmission unit 112 determines whether there is partial data to be uploaded in the terminal 10 (step S23).
If there is no partial data to be uploaded in the terminal 10 (see NO route in step S23), the data transmission process is terminated.

  On the other hand, when there is partial data to be uploaded in the terminal 10 (see YES route in step S23), the transmitting unit 112 confirms the last uploaded partial data and starts uploading the next partial data. (Step S24), the process returns to Step S21. Specifically, the transmission unit 112 confirms the transmitted identification information and transmits the identification information by duplicating the identification information.

Next, identification information storage table creation processing in the server 20 as an example of the embodiment will be described with reference to a flowchart (steps S31 to S34) shown in FIG.
The receiving unit 213 receives the moving image data 150 (a plurality of partial data) uploaded by the terminal 10 (step S31).
The combination processing unit 211 determines whether identification information is recorded in the received partial data (step S32).

If identification information is not recorded in the received partial data (see NO route in step S32), the identification information storage table creation process is terminated.
On the other hand, when identification information is recorded in the received partial data (see YES route in step S32), the combination processing unit 211 stores the identification information in the identification information storage table (step S33).

The combination processing unit 211 determines whether the received partial data is still present (step S34).
If there is no more received partial data (see NO route in step S34), the identification information storage table creation process is terminated.
On the other hand, if the received partial data still exists (see YES route in step S34), the process returns to step S32.

Next, data combining processing in the server 20 as an example of the embodiment will be described with reference to a flowchart (steps S41 to S47) shown in FIG.
The combination processing unit 211 sorts the records in the identification information storage table in the order of user ID, terminal ID, time information, and file name (step S41), and starts processing from the top of the sorted identification information storage table.

The combination processing unit 211 determines whether there are still unprocessed records in the identification information storage table (step S42).
If there are no more unprocessed records in the identification information storage table (see NO route in step S42), the data combination process is terminated.
On the other hand, if there is still an unprocessed record in the identification information storage table (see YES route in step S42), it is determined whether the user ID and terminal ID of the record are the same as the user ID and terminal ID of the previous record. (Step S43).

If the user ID and terminal ID of the record are not the same as the user ID and terminal ID of the previous record (see NO route in step S43), the data combination process is terminated.
On the other hand, when the user ID and terminal ID of the record are the same as the user ID and terminal ID of the previous record (see YES route in step S43), the combination processing unit 211 determines that the file name of the record is the previous record. It is determined whether the file name is the same (step S44).

If the file name of the record is the same as the file name of the previous record (see YES route in step S44), the process moves to the next record (step S47) and returns to step S42.
On the other hand, when the file name of the record is not the same as the file name of the immediately preceding record (see NO route in step S44), the combination processing unit 211 determines that the time information and GPS information of the record are the time information and GPS of the immediately preceding record. It is determined whether the information is the same (step S45).

If the time information and GPS information of the record are not the same as the time information and GPS information of the previous record (see NO route in step S45), the data combination process is terminated.
On the other hand, when the time information and GPS information of the record are the same as the time information and GPS information of the previous record (see YES route in step S45), the combination processing unit 211 has the same time information and GPS information. Two pieces of partial data including identification information corresponding to the records are combined (step S46). That is, the combination processing unit 211 combines the partial data with the later time after the partial data with the earlier time. Then, the process proceeds to step S47.

[A-3] Effect As described above, according to the network system 1 (the terminal 10 and the server 20) in the example of the present embodiment, the divided and transmitted data can be processed in the correct order.
Specifically, the recording processing unit 111 of the terminal 10 intermittently records a plurality of pieces of identification information including different time information in the data. Then, when the communication with the server 20 is interrupted, the transmission unit 112 receives the second data, which is the portion after the identification information recorded at the end of the first data, after the communication is restored. Is transmitted to the server 20. Thereby, the user can continue shooting without being aware of the connection to the network 100. Even when the upload completion timing to the server 20 is reversed between the first data (real-time transmission data) and the second data (delayed transmission data), the real-time transmission data and the delayed transmission data are arranged in the correct order. Can be combined.

  In addition, the receiving unit 213 of the server 20 receives a plurality of partial data in which a plurality of pieces of identification information including different time information are intermittently recorded from the terminal 10. Then, the combination processing unit 211 combines a plurality of partial data according to time series based on the time information. Specifically, the combination processing unit 211 determines that the identification information recorded at the end of the first data out of the plurality of partial data matches the identification information recorded at the beginning of the second data. The second data is combined after the first data. As a result, even when the upload completion timing to the server 20 is reversed between the first data and the second data, the first data and the second data can be combined in the correct order, and the user can upload Can play back the data immediately.

[B] Modified Examples The disclosed technique is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present embodiment. Each structure and each process of this embodiment can be selected as needed, or may be combined suitably.
[B-1] First Modification In the example of the embodiment described above, the recording processing unit 111 records the identification information in the moving image data 150 every predetermined time. However, the present invention is not limited to this. .

In the first modification of the present embodiment, the recording processing unit 111 records the identification information in the moving image data 150 when it is predicted that communication with the server 20 will be impossible.
FIG. 9 is a diagram illustrating an identification information recording process and a data transmission process in the network system as a first modification of the embodiment.
In the example shown in FIG. 9, the terminal 10 is mounted on a car 30, and the user is shooting using the camera 15 provided in the terminal 10. Further, it is assumed that there is a tunnel 40 in the travel route of the automobile 30, and communication between the terminal 10 and the network 100 is disconnected in the tunnel 40.

The recording processing unit 111 records identification information # 1 at the head of the moving image data 150 when the user starts photographing. In the example shown in FIG. 9, the identification information # 1 has the user ID Shira, the terminal ID 0002, the time information is 14:40:10 on June 18, 2013, and the GPS information is X1 and Y1.
Then, when it is predicted that the connection to the network 100 will be impossible, the recording processing unit 111 records the identification information # 2 in the moving image data 150. Specifically, the recording processing unit 111 identifies the moving image data 150 when, for example, the GPS information acquired by the GPS sensor 16 predicts that the vehicle 30 is approaching the tunnel 40 and the network disconnection (see symbol B1) is predicted. Record information # 2. In the example shown in FIG. 9, the identification information # 2 has the user ID Shira, the terminal ID 0002, the time information 14:40:20 on June 18, 2013, and the GPS information is X2 and Y3.

  For example, the storage device 13 or the recording medium RM stores, as a database, points at which network disconnection is predicted due to factors such as the tunnel 40 and areas where radio waves are weak. Then, the recording processing unit 111 predicts network disconnection by comparing the coordinates of the current location with registered coordinates on the database as needed. Further, for example, the recording processing unit 111 may check the radio wave intensity as needed, and predict network disconnection when the radio wave intensity is equal to or less than a threshold value.

The transmission unit 112 transmits real-time transmission data # 001, which is a part from the identification information # 1 to the identification information # 2 in the moving image data 150, on the cloud 200 (see reference B11).
On the other hand, the recording processing unit 111 stores, in the moving image data 150, the delayed transmission data # 002, which is the portion after the identification information # 2, in the storage device 13 or the recording medium RM of the terminal 10 (see reference symbol B12).

  Then, when the reconnection to the network 100 is predicted, the recording processing unit 111 records the identification information # 3 in the moving image data 150. Specifically, the recording processing unit 111 identifies the identification information in the moving image data 150 when, for example, the GPS information acquired by the GPS sensor 16 predicts a network connection (see reference symbol B2) when the automobile 30 leaves the tunnel 40. Record # 3. In the example shown in FIG. 9, the identification information # 3 has the user ID Shira, the terminal ID 0002, the time information is 14:40:33 on June 18, 2013, and the GPS information is X4, Y3.

  The transmission unit 112 transmits the real-time transmission data # 003 after the identification information # 3 recorded after the network connection to the cloud 200 (see reference B13). Further, in parallel with the transmission of the real-time transmission data # 003, the transmission unit 112 reads the delayed transmission data # 002 that could not be transmitted due to the network disconnection from the storage device 13 or the recording medium RM, and transmits it to the cloud 200.

Furthermore, the recording processing unit 111 records the identification information # 4 at the end of the moving image data 150 when the user finishes shooting. In the example shown in FIG. 9, the identification information # 3 has a user ID of Shira, a terminal ID of 0002, time information of June 18, 2013 at 14:40:39, and GPS information. X5, Y3.
In other words, the recording processing unit 111 determines in step S13 in the flowchart illustrated in FIG. 5 whether the connection to the network 100 is impossible or the connection is predicted to be restored.

As described above, the network system 1 (the terminal 10 and the server 20) in the first modified example of the present embodiment has the same effects as the network system 1 (the terminal 10 and the server 20) in the example of the above-described embodiment. The following effects can be achieved.
The recording processing unit 111 records the identification information in the data when it is predicted that communication with the server 20 cannot be performed. As a result, the number of pieces of identification information recorded in the data can be minimized, so that the data capacity can be reduced and the load on the network system 1 (terminal 10 and server 20) can be reduced. it can.

[B-2] Second Modification In the example of the above-described embodiment, the recording processing unit 111 records the identification information in real time in the moving image data 150 captured by the user with the camera 15, but the present invention is not limited thereto. Is not to be done.
In an example of the second embodiment, the recording processing unit 111 records identification information in the moving image data 150 previously captured by the user. In this case, the terminal 10 may not be connected to the camera 15 or the GPS sensor 16 so as to be communicable.

Specifically, the recording processing unit 111 uses, for example, the ID of the user who uploads the moving image data 150 as the user ID, the ID of the terminal used for shooting as the terminal ID, and the date and time of shooting as the time information. The position information at the time of shooting is recorded in the moving image data 150 as GPS information.
Thus, the network system 1 (terminal 10 and server 20) in the second modification of the present embodiment also has the same effects as the network system 1 (terminal 10 and server 20) in the example of the embodiment described above. The following effects can be achieved.

The user can transmit the previously captured moving image data 150 to the server 20 without being aware of the connection to the network 100.
[B-3] Third Modification In the example of the embodiment described above, the recording processing unit 111 records the identification information including the user ID, terminal ID, time information, and GPS information in the moving image data 150. However, the present invention is not limited to this.

For example, when the same user uses a plurality of terminals 10 to photograph at the same time, a plurality of partial data including time information in the same time zone is divided and exists on the cloud 200. I have no idea how to combine them.
In the third modification of the present embodiment, the recording processing unit 111 records identification information including a group ID in the moving image data 150 in addition to the user ID, terminal ID, time information, and GPS information. Here, the group ID is identification information for managing a plurality of terminals 10 together.

The combination processing unit 211 combines the moving image data 150 when the group ID, the time information, and the GPS information are the same even if the user ID or the terminal ID is different from each other in the two pieces of identification information.
As described above, the network system 1 (the terminal 10 and the server 20) in the third modified example of the present embodiment has the same effects as the network system 1 (the terminal 10 and the server 20) in the example of the above-described embodiment. The following effects can be achieved.

The recording processing unit 111 records identification information including a group ID in the moving image data 150 in addition to the user ID, terminal ID, time information, and GPS information. Thereby, even if it is the moving image data 150 image | photographed using the some terminal 10, the combination process part 211 can be combined in the correct order.
[B-4] Fourth Modification In the example of the embodiment described above, one terminal 10 performs the recording process and the transmission process of the moving image data 150 and the reproducing process of the moving image data 150. It is not limited to this.

  In the fourth modified example of the present embodiment, the first terminal 10 performs recording processing and transmission processing of the moving image data 150, and the second terminal 10 performs reproduction processing of the moving image data 150. That is, different terminals 10 perform recording processing and transmission processing of moving image data 150 and reproduction processing of moving image data 150, respectively. In this case, the CPU 11 of the first terminal 10 may not have the function as the reproduction unit 114, and the CPU 11 of the second terminal 10 may not have the function as the recording processing unit 111. good.

As described above, the network system 1 (the terminal 10 and the server 20) in the fourth modified example of the present embodiment has the same effects as the network system 1 (the terminal 10 and the server 20) in the example of the above-described embodiment. The following effects can be achieved.
Even if the terminal 10 that performs the recording process and the transmission process of the moving image data 150 and the terminal 10 that performs the reproducing process of the moving image data 150 are located at separate locations, the user can immediately reproduce the uploaded data.

[B-5] Fifth Modification In the example of the embodiment described above, the combining processing unit 211 combines a plurality of partial data into one moving image data 150, and the transmitting unit 212 transmits the combined moving image data 150 to the terminal 10. However, the present invention is not limited to this.
Also in the fifth modified example of the present embodiment, the join processing unit 211 creates a sorted identification information storage table as illustrated in FIG.

The combination processing unit 211 determines that identification information corresponding to records having the same user ID and terminal ID and the same file name is identification information included in the same partial data. In addition, the combination processing unit 211 instructs the transmission unit 212 to perform streaming distribution of the partial data including the identification information to the terminal 10.
The combination processing unit 211 determines that identification information corresponding to records having the same user ID and terminal ID, and the same time information and GPS information but different file names is the same identification information. In addition, the combination processing unit 211 instructs the transmission unit 212 to continuously distribute the partial data including these pieces of identification information to the terminal 10.

Then, the transmission unit 212 performs streaming delivery to the terminal 10 as a single moving image data 150 by continuing a plurality of partial data.
Thus, the network system 1 (terminal 10 and server 20) in the fifth modification of the present embodiment also has the same effects as the network system 1 (terminal 10 and server 20) in the example of the embodiment described above. Can do.

[B-6] Sixth Modification In the example of the embodiment described above, the combination processing unit 211 of the server 20 performs the partial data combining process, but the present invention is not limited to this.
In the sixth modified example of the present embodiment, the CPU 21 included in the server 20 does not function as the combination processing unit 211, and the reproduction unit 114 of the CPU 11 included in the terminal 10 functions in the same manner as the combination processing unit 211.

That is, similarly to the above-described exemplary embodiment, the transmission unit 112 of the terminal 10 transmits a plurality of partial data in which the recording processing unit 111 has recorded identification information.
The receiving unit 213 of the server 20 assigns a file name to each of the received partial data and stores it in the storage device 23, and the transmitting unit 112 stores the plurality of partial data stored in the storage device 23 based on a request from the terminal 10. Is transmitted to the terminal 10.

Then, the reproduction unit 114 of the terminal 10 performs the same processing as the combination processing unit 211 in the above-described exemplary embodiment to combine the plurality of partial data received by the reception unit 113 into one moving image data 150.
Thus, the network system 1 (terminal 10 and server 20) in the sixth modification of the present embodiment also has the same effects as the network system 1 (terminal 10 and server 20) in the example of the embodiment described above. The following effects can be achieved.

Since the server 20 only transmits and receives data and stores it in the storage device 23, the load on the server 20 can be reduced, and a conventional server can be used as it is without rewriting the program.
